COMPUTINGCENTER

In early August, Computing Centerstaff installed the most significant hard -ware upgrades to GLADSTONE andDARKWING in several years. These newsystems provide dramatic improve-ments in p erformance and storage ca-pacity over the older hardware theyare replacing.

Each n ew system is a Sun E5500 with160 GB of storage for u sers directories.The new DARKWING has 8 400mhz CPUs

and 4 GB of RAM. The new GLADSTONEhas four 400mhz CPUs and 2 GB ofRAM. This represents app roximately afourfold increase in raw computingpow er as well as disk capacity for eachsystem. There is plenty of room forfuture CPU and disk expansion onthese new systems, too.

Disk I/ O w ill be much faster becausethe system now uses hardw are RAID

disk trays. These disk interfaces sup -port u p to 40 Mb/ sec transfer rates, aneightfold increase in I/ O speed s fordisk access. Both system s make use ofgigabit ethernet network interfaces,wh ich operate at 10 times the speed ofthe older 100 megab it ethernet cards.

The new systems run the Solaris 2.7operating system that supp orts a true

64-bit instruction set (as opposed to32-bit instructions on the old systems).To take advan tage of this, use the newSun Workshop 5.0 Comp ilers that arealso now installed on the systems.

Because of the additional storage avail-able, the standard u ser disk quota hasbeen increased from 10 MB to 20 MB onboth system s. Mail delivery has beenstandardized to d eliver to users hom edirectories on DARKWING as it alreadyis configured on GLADSTONE. Thisshould imp rove performance as wellas eliminate the need to track a sepa-rate mail quota on DARKWING.

Many compute-intensive, third-partyapplications are supported on bothDARKWING an d GLADSTONE, includingmatlab, SA S, SPlus, Mathematica, andSPSS. Over time, many of the app lica-tions supp orted on the ALPHAclusterwill be moved to these Sun systems(see page 16).

Major UNIX Upgrades!s

UOnet and Oregon Gigapop GetSign ificant Boost from 3ComThis Jun e, the Un iversity of Oregonscompu ter network and high-speed net-working infrastructure received a bigboost from 3Com, the leading pro-

vider of campus networking solutions.

3Com, an Internet2 corporate partner,donated $100,000 to finance a ten foldboost in the core speed of the camp usnetwork (UOnet), and to provide gi-gabi t hardware for the OregonGigapop, wh ich p rovides high-speedconnectivity to Oregon s research in-stitutions.

The UO is one of approximately 150un iversities participating in Internet2

and the Abilene Network, a nation-wide fiber-optic network that re-searchers a re us ing to push thebounds of high-performance com-

pu ting on the Internet and developthe next generation of Internet ap-plications. 3Com s gift is being u sedto up grade UOn et from fast ethernetspeed s (100 megabits per second) togigabit ethernet speed s (1,000 mega-bits per second)roughly 18,000times faster than a home desktop(56K) modem that connects persona lcomp uters to the Internet.

The UOs participation in the AbileneNetwork is partially funded by grants

New systems providedramaticimprovements instorage capacity andnetwork performance

Faculty /St affFaculty and staff are eligible for ac-

counts on either DARKWING or OREGONor both.

D ARKWING. DARKWING is a large sha redSun Enterprise 5500 system runningSolaris 2.7 (Sun's vers ion of UNIX). Forinformation on its configuration, seethe ar ticle in th is issue on page 2.

OREGON .OREGON is a large Compaq(formerly Digital Equipment Corpor-ation) 7630 system ru nn ing OpenVMS/AXP. OpenVMS/ AXP is a uniqueoperating system that is notbased onUN IX; its comm and s are actually mostreminiscent of MS DOS. It is the sam eope r a t i ng sys t em used on t heun iversity's adm inistrative computersystems.

For most faculty and staff, eitherDARKWING or OREGON will work fine forroutine email purp oses and for servingtypical web pages. Beyond that, sys-tem choice is prim arily a matter of per -sonal preference, as long as the soft-ware you wan t to use is installed on the

system you pick (see the software charton the following page).

If you do establish accounts for your-self on both DARKWING an d OREGON,please be sure to rou tinely check youremail on both systems, or forward youremail from you r less pr eferred accoun tto your favorite account. Passwordsand files are not shared betweenDARKWING an d OREGON.

Undergraduate Students

Undergraduate student accounts areautomatically created on GLADSTONE.GLADSTONE is a Sun Enterp rise 5500 ma-chine and , like DARKWING, it run s Solaris2.7, Sun's version of UNIX.

GLADSTONE accounts can be used forelectronic mail, serving personal webpages. Beginning this year, we're also

offering an expanded range of aca-dem ic software on GLADSTONE, such asSA Sand Mathematica.

Und ergraduate stu dents can also self-authorize themselves for an OREGONaccoun t if they p refer OpenVMS overUNIX, or if they simp ly wan t a secondaccount to u se as a backup .

Graduate StudentsGradu ate stud ents automatically haveaccounts c rea ted for them onDARKWING; how ever, if they w ish, theycan also self-authorize accounts onGLADSTONE an d OREGON.

Other Syst emsYou m ay also see these other systemsmentioned from time to time:

DONALD and DAISY.DONALD and DAISYarelarge Compaq administrative systemsrunning OpenVMS/ AXP. The p rimaryapp lication running on these systemsis BANNER, an administrative appli-cation environment based on Oracle, apopu lar large system d atabase.

DONALD an d DAISY share d isk, printersand some other resources with OREGON,but access to DONALD an d DAISY is re-stricted to staff members w ho are p er-forming administrative tasks likegrade processing and payroll.

ALPHA. ALPHA is the nam e for a clusterof five Comp aq 500 workstations that(prior to DARKWING's upgrad e) has beenused exclusively for computationallyintensive academic computing jobs.Machines in the ALPHAcluster runComp aq Tru64 UN IX (formerly DEC

UNIX). Individual members of theA L P H Acluster have water-relatednam es, such as hotspring, thunderstorm,river, downpour, and geyser.

ALPHA use will be gradually phasedout th rough the end of 1999, at wh ichtime most comm ercial third p arty soft-ware w ill be moved from ALPHA ontoDARKWING.

User d irectories on DARKWING are ex-ported to the ALPHA systems, so you'llsee all your files from DARKWING on theALPHA workstations automatically,and any changes you make on eitherDARKWING or ALPHA will autom aticallybe reflected on the oth er system.

However, because DARKWING runs adifferent version of UNIX than ALPHA,(Solaris vs. Tru64 UN IX), you cann otcompile your p rogram on one systemand then r un it on the other (i.e., if youwan t to run your FORTRAN p rogramon DARKWING, compile it on DARKWINGand ru n it on DARKWING).

No m ail or w eb service is provided onthe ALPHAcluster.

To log on to machines in theA L P H A c lus te r , use your normalDARKWING username and password (nospecial authentication is required forDARKWING users to be ab le to log in onthose systems). Note tha t if you log invia ssh to the ALPHAcluster, you m ustdesignate a specific system (e.g.,hotspring, thunderstorm, river, down-

pouror geyser) rather than logging in

directly on alpha.uoregon.edu (thecluster's gen eric name).

D OLLY: DOLLY is an experimentalBeowulf cluster, one of two in theOregon University System. It consistsof 14 Pentium Pro nodes connectedvia a p rivate fast ethernet network toa nod e controller, and run s the PVMand MPI message passing libraries ontop of Redhat Linux.

If you are a faculty member or gradu -ate student interested in gaining ac-

cess to DOLLY to run PVM or MPIcodes, please contact Hans Kuhn([email protected]) for moreinformation.

What About NT?The Computing Center does not cur-rently provide accounts on any N T-based system.

Your Com putin g Account: Wh at LargeYour UO computing account gives you access to one or more large timesharing systems. To help youchoose the system that best suits your needs, weve described each of them in some detail below .

What About Dialin

Access?

In addi t ion to your account onOREGON , DARKWING or GLADSTONE, youmay also get a modem account an d

password so that you can dial infrom off campu s to the University'smodem pool.

Note that our modem pool is rela-tively small and is intend ed for useno more than a couple of hours aday p er user (or 14 hou rs a week). Ifyou need dedicated or near dedi-cated access, you w ill want to contacta commercial Internet Service Provider(ISP). One list of ISPs is available athttp://www.thelist.com/

What About Class/Depart ment al

Account s?

If you are teaching an u nd ergradu-

ate class and your students needaccess to software available only onDARKWING, temporary accounts (so-called ST student accounts) canbe created for their use. The courseinstructor should contact ConnieFrench, the Computing Center ac-counts clerk, for m ore informationabout d oing this.

If you are a departm ent or un iversity-recognized institute, lab, or organiza-tion, you can arrange for a depart-

men tal accoun t. Such accoun ts are of-fered solely to provide an authorita-tive and u nchanging home for depart-men tal web pages and official depart-mental email, and must be officiallyrequested by the person responsible

for the accoun t. Modem accounts w illnot be created for departmentaluserids.

DSL Modem Tech n ology Prom ises

Since DSL is a relatively new technol-ogy, many people still have generalquestions about what it is and w hat it

can do. This article attempts to answ ersome of those questions and d escribessome of the DSL options now avail-able locally.

Sowhat is DSL?

DSL stands for Digital SubscriberLine. In a nutshell, its a new mod emtechnology for allowing high-speedInternet access to homes and small busi-nesses over existing telephone wires.

The nam e DSL comes from tw o termsthat together d escribe the techno logy:digital and subscriber lines. Thefirst term refers to the fact that DSLdata transmission is based on digitalencoding (i.e., data is represented asones and zeroes); while subscriberlines is the phone companies his-toric term for their customer wiring.The key d ifference between a DSL mo-dem and a traditional modem is thatthe DSL modem op erates at very highspeed and utilizes digital signaling.

Why should you care?

DSL could be of interest to certainindividuals or small businesses wh ohave a p ressing n eed for a high-speedconnection to the Internet, and whoare eligible for the ser vice. DSLs per -formance can be ten tim es faster thanthat o f existing V90 or 56K modem sand , depend ing on the type of service

that is purchased, even faster than that.The cost of DSL is typ ically a fraction ofother trad itional high-speed wide-areatechnologies, such as ISDN, T1, orFrame Relay, and DSL service is rap-

idly becoming available in a num ber ofcities throu ghou t the U.S.

The promise of DSL is to extend high-speed Internet access all the way to thehom e or small business for a relativelymod est price. This can enable activitieslike telecommu ting, videoconferencing,file sharing, web serving, or any othernetwork activity that depends on analways-on connection, and a connec-tion that has a bandwidth greater thanwh at has p reviously been available us-ing traditional dialup technology.

Who is eligible?

In general, only customers wh o arewith in 2-3 miles of a phon e compan yscentral office are able to receive theservice. DSL is distance-limited, so

people in remote areas should notexpect to be able to subscribe. Thebest way to find out if you are withinrange is to check w ith the ph one com-pan y prov iding the service. Locally,USWest is the only curren t provid er;how ever, other comp etitive local ex-change carriers may also begin toprovide service in the near future.USWest maintains a web site athttp://megawot.uswest.com/availability/

There are other institutions that candeploy DSL technology. In specialcases, the University of Oregons Net-work Services has utilized DSL toestablish connections from nearby off-campus bu ildings to the campus net-work. These arrangements are typi-cally only considered when the cus-tomer h as a direct affiliation with theuniversity and has ad equate fund ingto support the service.

What is an ISP in terms

of DSL service?

There are usually two entities in-volved in a complete DSL servicepackage: one that prov ides the DSLcircuit, and another that provides

Intern et services. These en tities canbe the same company or two differ-ent companies. You can purchaseyour DSL modem and order yourDSL line from USWest, and theywill direct you r traffic either to th eirown Internet Service Provider ,USWest .Net , or to a qua l i f i edInternet Service Provider (ISP) ofyour choosing.

The key differencebetw een a DSL

modem and atradit ional modem

is that the DSLmodem operates at

very high speed andutilizes digital

signaling

s The promise of D SL isto extend high-speedInternet access all theway to the home orsmall business for arelatively modest price

How fast is D SL?The speeds achieved u sing DSL dependon a number of factors. Currently, atypical USWest DSL connection has adownload rate limit of 640Kbps (kilo-bits-per-second) and an up load limit of272Kbps. Actua l perform ance will varydep ending on the current utilization ofthe intervening network and the per-formance of the sending and receivingmachines involved in the file transfer.File downloads at rates of 40 to 50 KB/ s(kilo-bytes-per-second) are not un com-mon. Faster rates can be obtained bypurchasing higher levels of service atadditional cost.

In general, an ISP provides servicessuch as an IP address for your com-pu ter and the routing of your traffic tothe Internet. ISPs can also provideemail accoun ts and other services, such

as web page hosting and n ews serveraccess. In the simplest case, USWestcan act as both your DSL line providerand your ISP. In this case, your ph onebill, DSL line charges, and ISP chargeswould all come from the same com-pany. There are also a nu mber of com-peting ISPs, such as The Pond andWillamette.Net. A complete list of par-ticipating ISPs is prov ided by USWestat http://www.uswest.com/products/data/dsl/isplist.html

Why would I choose oneISP over another?

While you will generally have onlyone choice in terms of who is prov id-ing you r DSL line (USWest), you m ighthave a number of choices when itcomes to selecting an ISP. The serv icesoffered by each ISP vary widely, socare should be taken when makingthis choice. Youll need to consider anu mber of factors, including availableband width to the Internet, routing to-pology, the provisioning of static or

dynam ic IP add resses, email accoun ts,disk space for web p ages, and dom ainname registration for business use.

The easiest way to determine whichservices are offered is to call the ISPand talk to a customer service repre-sentative. In any case, it is usually nottoo d ifficult to sw itch to a d ifferent ISPor to u pgrad e to a higher level of ser-vice at some later date if you decidethat additional services are required.See page 10 for a discussion of alterna-

tive services.

What happens to my

phone line?

DSL has adequate capacity to carrytelephone voice traffic along with datatraffic. The two types of traffic areintegrated at the DSL modem, andthen later split apart at the phone

companys central office. The twochannels coexist amicably, and it isnever the case that you w ont be ableto use your p hone because someone isusing the computer, or v ice versa.

In order to protect telephone devices(which opera te on lower frequencies)from the higher frequencies of theDSL da ta chann el, small filters mustbe pu t inline between the telephoneand the DSL mod em. Once the filtersare in place, the phone operates asusual.

How much does it cost?

Initial setup of a DSL connection w illrequire a DSL mod em and the instal-

lation of the modem and inline ph onefilters. Installation is relatively sim ple,and this charge is usually waived ifperformed by the customer. The costof the modem will vary, dependingon the availability of pr omotiona l dis-counts. Likewise, initial setup costscan vary from $0 to $450, depend ingon the type of hardware, method ofinstallation, and availability of pro-motional discounts.

For example, the Cisco 605 internal

mod em is sometimes provided at nocost. If you p erform you r own instal-lation, this can end up being a nocost setup. Other typical scenariosmight involve p urchasing the exter-nal modem for either $50, $100, or$300. If the customer chooses on-site

installation by a USWest technician,this can ad d a cost of $150.

The monthly charge for DSL line ser-vice also may vary. Depending on the

bandw idth and the type of service youchoose, the cost can be $20, $30, $65,and up per month. For an always-onconnection with a dow nload speed of640Kbps (kilo-bits-per-second) andupload speed of 272Kbps, the $30/month charge is typical.

The mon thly charge for ISP service istypically $20 a m onth for basic service.For higher level services that includestatic IP add resses or web hosting, ex-pect to pay $35 a month or more. Inadd ition, you w ill continue to p ay stan-dard charges for phone service if yourphone line is incorporated into yourDSL service.

So the overall monthly cost for DSLservice, including ISP, will be on theorder of $50 a mon th for a typ ical instal-lation. For users w ho need a faster con-nection to the Internet and the expandedservice capabilities that DSL can pro-vide, these types of charges are notunreasonable.

What is bridged-mode

versus PPP-mode?Another differentiating factor betw eenISPs is w hether they accept DSL trafficthat is in bridged mod e or in PPPmode. The primary differences be-tween these two mod es of operationare explained below.

Bridged Mode. In bridged m ode, thecomputer is assigned an IP address,but the packets from the customersmodem are dumped directly on theISPs Local Area Network (LAN). Theadvantage of this technique is that it

makes the custom er app ear to be local;that is, services that requ ire broadcast-ing or non -IP pro tocols can operate asthey normally would, assuming theISP accepts or r outes an y of these pro-tocols. The disadvantage is that theISP then has to process all of this extratraffic, so this can p lace a greater loadon the ISPs LAN.

PPP Mode. Things are not quite sostraightforward in PPP mod e. In thismod e, the DSL modem is assigned anIP add ress and a route to an IP add ress

at the ISP. Typically, the customerscomputer also requires an IP add ress.In this case, the d ata thats sent to theISP must first be routed by the DSLmod em. Most ISPs will only accept IPtraffic in this configuration; neitherbroad casts nor other non-IP pro tocolswill be allowed . The advantage is thatthe ISP is not burdened with broad-cast traffic or the handling of non-IPprotocol traffic, so th eir overall LANperformance may improve. The dis-advantage, generally, is the extra com-

plexity involved in the IP add ress con-figur ation of the custom ers compu terand DSL mod em.

What is NAT?In the gen eral case, the choice betweenbridged-mode and PPP-modewou ld be of little concern to the aver-age DSL user. But if you chooseUSWest as your ISP, in the serviceofferings that are of lower cost you

will not only be required to use PPP,youll also be required to use some-

thing called NAT. NAT stands forNetwork Address Translation. Its amethod of conserving IP addresses byusing nonroutable private IP ad-dresses on internal computers. NATcan also be used as a m ethod for hid-ing internal computers from remoteconnections to make them mor e secure.

Drawbacks. As you might expect, theNA T method sacrifices some usab ility.

The DSL modem can easily translaterequests originating from the customer

site going to outside services. When aconnection is initiated from the cus-tomer site, the DSL modem automati-cally translates from the private ad-dress of the customer compu ter to theDSL modem addressthe public ad-dress that the rest of the w orld sees.

But for connections initiated from a re-mote site, the private address assignedto the customer computer is nonrou tableby anything other than the customersown DSL modem . So it becomes d ifficultto offer services from the customer site to

remote u sers. Since the customers com-pu ter add ress is nonrou table, the remotesite has no way to make the initial con-nection to the customer ad dress (for ex-ample, hosting a web server or setting u pan FTP site becomes a real challenge).

NAT can also imp act many of the morecomplex IP network protocols that carryIP addresses in them as part of theirdata. NetMeeting conferencing proto-col is one su ch examp le. PPTP, a secu-rity protocol, is another example of aprotocol that has trou ble working w ithNAT. NAT also performs poorly onservices that are UDP based (i.e., notconnection oriented ), such a s IRC serv-ers and gam e servers.

So while NAT can be good for overallnetwork performance and good forthose who w ant the add ed security of anonrou table IP ad dress, it can imp ose aburden on those who want to offerservices from their computer. Users

wh o want to offer web pages or anFTP server wou ld be challenged . And

the loss of the ability to u se serviceslike N etMeeting, IRC, or gam e serv-ers can be significant to some u sers.

Are there N AT alternatives?A num ber of workarounds or alterna-tives to NAT d o exist. The most obv i-ous of these is to choose one of thehigher-cost ISP service packages fromUSWest that provides static routableIP addresses. USWest classifies theseservice offerings, wh ich d o not involvethe use of NAT at the customer site, as

Office or Business packages.Another alternative is to choose anISP that offers bridged-mod e service.Some ISPs offer both bridged-modeservice and a static routable IP ad-dress for the customer computer aspar t of their base offering. This can bean attractive option, assuming th e ISPalso provides adequate service inother areas, such as routing topologyand overall bandwidth.

The more savvy user can make modi-

fications to the settings of the DSLmod em to allow NAT to successfullypass specific protocols. People r eferto this technique as setting NATrules. Because this p rocess can some-times be complex, and because eventhe IP address of the modem maychange over time, this is not the easi-est approach and may not alwaysachieve the desired goals.

Another way to get around N AT is topurchase the Cisco 605 internal DSLmodem card instead of the Cisco 675

external modem. The use of the inter-nal modem card eliminates the needfor NAT, since the card itself hand lesall of the netw ork traffic. While the IPaddress used by the card may stillchange from time to time, NAT willnever be involved . The use of an inter-nal card d oes involve some trade-offs,however. You m ay not wan t to attemptthis method at a site where more thanone computer will be connected.

Over the summer, the VMSclusters

mail transport software w as upgrad edto PMDF v. 5.2, affecting both p asswordand mail folder conventions. Thesechanges are described below, w ith tipson how to avoid p roblems.

VMS Passw ordExpiration EnforcedSince the upgrade, both IMAP (InternetMail Access Protocol) and POP (PostOffice Protocol) mail servers now en-force VMS passw ord expiration. This

means that w hether youre using IMAPprograms (e.g., Mulberry, Eudora Pro,Netscape Communicator, Outlook Express)or POP programs (e.g., Eudora), youwon t be able to access your m ail if yourpassword has expired.

To set a new password under VMS,you have tw o choices:

1. Log in to VMS vi a Telnet and fo l-

low the steps in the password change

dialogue. (The p assword change willtake effect imm ediately.)

2. Log into the A UTHORIZE systemvia Telnet and submit a password

change request. (To use AUTHORIZE,you must know your BANNER ID/SSN and your six-digit PAC n um bers,and there may be as much as a 15-minute delay before the passwordchange takes effect.)

Once you have changed your pass-word , set your m ail program to recog-nize it. This procedure varies accord-

ing to which mail program you u se.The main thing to keep in mind is thatif you instruct your m ail program tosave your password (so you wonthave to typ e it in each time you try toaccess your m ail), you mu st remem-ber to reset it every 180 days, when itexpires on VMS.

Password Problems? If youre stillhaving password trouble, call 346-4403 for assistance.

Intrusion DetectionAnother new feature of the upgradeis that both IMAP and POP serversnow enforce intru sion detection. This

means that a VMS account is lockedfor a period of time following fivefailed login attemp ts. While this fea-ture is designed to p rotect you, youcould inad vertently lock your self outof your mailbox if you typ e the wron gpassword five times in a row .

Mail Folder SetupVMS mail folder conven tions can be abit tricky. While the new PMDF IMAPserver supports hierarchical folders,we d ont recommen d u sing them be-

cause they can cause problems. Itsalso important to avoid using rootfolder p aths (e.g., folder names w ith a/ or ~ character in them).

If youre using an IMAP program su chasMulberry or Outlook Expressand areexperiencing problems accessingsome of your mail folders, contactMicrocomputer Services (346-4412,[email protected]) for help.

SecurityThe VMS upgrade has the ad ded featureof protecting p lain text passwords from

detection as they are transmitted acrossthe netw ork by IMAP and POP clients, iftheclient supp orts it. Transport Layer Se-curity (TLS) also secures the contents ofemail communications.

Outlook Express 5 an d 2000 fully sup-port TLS for IMAP, POP, and SMTPclients. Netscape Commun icator 4.621supp orts it for IMAP and SMTP but notfor POP; andEudora Lite an dEudora Prodo n ot supp ort it at all.

What is the cost?

Are the most up-to-date dataanalysis and graphical techniquesavailable?

Where can I find technical supp ort?

Do I need p ortability, or will astationary workstation suffice?

Statistics packages at the UO easily m eetmost of these requirements. Considerthree major state-of-the art statistics pro-gramsSA S, SPSS, and Splus:

wh atever software you select, always,always, always DOCUMENT YOURWORK! Its extremely important tokeep a current record of what you did,and wh y. Preserving your steps in asyntax file can save you a g reat deal oftime and confusion in the long ru n.

Beware of Quick and Easy

SolutionsWhile easy point-and-click methodsare available with some PC versions ofstatistics program s, these method s failto automatically document your stepsinto a syntax file. This approach isapp ealing bu t treacherous, because youcan easily lose track of your sequence ofsteps or the formulas you applied. Italso takes more time to rep eat a similaranalysis later on or to transfer the da tato another u ser withou t confusion. Thisis particularly true of recent versions ofSPSS for Windows, where (unlikeEXCEL) formulas are not saved in theSPSSspreadsheet.

Advantages of Writing Code the

Syntax Method:Assuming you canuse a text editor, one of the realstrengths of writing code in SA S,SPSS,Splus, and other statistics program s isthat this approach documents the en-tire process. All the steps you take,from initial da ta inpu t to final analy-sis, are clearly written into the pro-gram . This syntax method is also ahighly efficient w ay to p roceed if youhave a lot of repetitive tasks or manyvariables to process.

The SAS Advantage. One of the greatstrengths ofSA Sis that writing a syn-tax file gives you an automatic docu-mented program . Many users balk atwriting programs, assuming its tood ifficult. While the SA Slanguage may

at first seem complex, the basics areactually quite easy and the selection ofstatistical procedures is not nearly ascomplicated as you might imagine.Also, if you have any type of datacollected over time (e.g., repeated mea-sures), or if you n eed to do program-ming or m erge separate files together,SA Sis the best choice.

Writing Code in Splus. If you re ma th-ematically inclined, think in matrixterms, and like to write your own pro-

grams, Splus offers man y nice featur esand would be a good choiceespe-cially for compu ter-intensive meth odssuch as the bootstrap.

Windo w s 3.1 Users: Tim e to Upgrade!require purchasing a new machine.Fortun ately, compu ters have becomeconsiderably less expensive. Aperfectly usable machine can now bepurchased for between $1,000 and$1,500. We recommend purchasing

name-brand equipment with solidwar r an t i e s and good cus t om ersupp ort. They may cost a bit more, butthe time you save in repair and w aitingcosts is well worth the investm ent.

For newer hardw are, we recommendrunn ing Windows 98, as Windows 95does not have reliable support for anumber of newer devices, includingUSB buses that are included on mostrecent machines.

Time. Learning a n ew op erating sys-tem and transferring your data willtake time. While this can be a seriousdeterrent to making the switch, it'svery necessary, because sharing datawith o thers w ill become more d ifficultas Windows 3.1-compatible softwarebecomes further ou tdated. A case inpoint is the new Microsoft Office 2000product. By default, Microsoft Wordin Office 2000 cannot open or save anyDOS versions of MSWordfiles (includ-ing Wordfor DO S version 6 files). Youcan install additional file conversions

in Office 2000 to get aroun d this prob-lem, but these additional file convert-

PMDF. PMDF is the ma il transfer soft-ware that includes SMTP, POP3, andIMAP servers. An important changeresulting from the up grade is that POP3and IMAP now check for expired pass-words and will not allow access tousers whose VMS password has ex-pired (see Use OREGON for Email?

DuckWeb Adds Two Major

New Features

Web for Students: Students now havethe option of usingDuckWeb for courseregistration. Web for Students provides

online, web-based course registrationwith essentially the sam e capabilities andsupport that students have had withDuckCall since 1991.DuckCall access byphone (for such functions as registration,schedule and grade information) remainsunchanged, and students can continueto use it as well.

Web for Faculty: After a su ccessful p i-lot test run d uring spring term, another

Web for Students and Web for Facult y enable onlinecourse registration and secure access to academic record

new DuckWeb module called Web forFaculty is now available to academicdepartment staff and faculty.This mod-ule provides n ew services at tw o d if-ferent a ccess levels: a full access level,

with increased supp ort for faculty andstaff who ad vise stud ents; and a lim-ited access level, with imp roved accessto class list and term schedule infor-mation only.

Web for Faculty provides easy, secureaccess to student academic records,and transcripts can be organized inthree d ifferent ways to assist with theadvising process. Accessing, printing,

and dow nloading class list informa-tion is considerably simpler and moreefficient than via BQS and othermeans.

For additional information on either ofthese new DuckWeb offeringsinclud-ing questions on access to Web for Fac-ulty contact Associate Registrar BrianScholten, ([email protected],346-3195). Please direct comments, ques-tions or problem reports to either JimBouse (Registrars Office: 346-2929,[email protected]) or JimBohle (Computing Center: 346-1706,[email protected]).

tively little attention has been paid tosecurity for everyday tasks like readingemail, editing w eb pages, or logging into other machines. Yet your usernameand password are very valuable infor-mation to an attacker. Once these are

known, intruders may be able to compro-mise the computer to which you log in,damage or erase the contents of your ac-count, or impersonate you on the Internet.

There is a w ay to p revent this, however.Secure Shell (ssh) provides users withsecure authentication, using public keymethods and a secure connection to anyremote host running an ssh server, suchas DARKWING or GLADSTONE. Free imple-mentations ofsshare available for Win-dow s and UNIX; and a comm ercial oneis available for the Mac. Youll find the

TerraTerm sshclient on both the fall 1998Duckw are CD and the recently releasedfall 1999 Duckware CD.

For more information abou t ssh, sendemail to [email protected],[email protected] , o [email protected]

ssh is a secure encrypted replace-ment for telnetand rlogin, and we

encourage all system administra-tors to offer ssh on any multiuserhost they administer.However, somessh installation instructions we'veseen direct the ad ministrator to ru nmake-ssh-known-hosts as part of thessh installation p rocess. We ask tha tyou NOT, repeat NOT, run make-ssh-known-hosts if/ when you install ssh.

Why? make-ssh-known-hosts at-tempts to walk all hosts in a givendomain, retrieving the public keysfrom a ll the hosts that are runningssh

in that domain.

In a relatively large netw ork suchas the Un iversity of Oregon 's, thatcan generate a tremendous amou ntof unnecessary traffic, and it canalso trigger intrusion logging soft-ware on man y hosts as ssh connec-tions from unexpected hosts areobserved.

Because sshwill autom atically accu-mulate public keys from the hostsyou use as you connect to them,there is no need to routinely runmake-ssh-known-hosts.

If you brow se the web, you m ay wantto take advantage of the new FastTrack

web server on the VMScluster (seehttp://web-vms.uoregon.edu). FastTrackwas installed as an alterna tive tonota rep lacement forthe Oh io State Uni-versity web server (seehttp://www-vms.uoregon.edu).

Advantages ofFastTrackFastTrack 3.01 offers several advan-tages over its VMS counterpart, theOhio State University web server, e.g.:

1. It sup ports more standard CGIprogram s/ scripts written in C, DCL,

or Perl

2. It supp orts SSL security more easily

While FastTrackoffers some app ealingoptions, Ohio States server retainssome advantages:

1. It runs/ initiates CGI programs faster

2. It can run CGI programs on anyVMScluster node, while FastTrackrunsthem only on the node where FastTrackis running.

Campus Departm ents: UseVirtual Hosts to Stream lineUO Site AddressesBy Hans Kuhn

[email protected]

Watch URL Syntax

fo r DARKWING Web

Pages!

Some day, certain virtual hosts (e.g.,www.uoregon.edu)may be carved off

from DARKWING proper and placed on asecond machine. To prepare for thiseventuality, its important that youpay attention to your URL syntax.

If youre creating web pages under apu blic_html directory on DARKWING, besure to use darkwing.uoregon.edu inyour URL instead of a virtual hostname such as www.uoregon.edu(e.g.,use http://darkw ing.uoregon.edu/~joeljainstead of http://w w w .uoregon.edu/~joelja). This ensur es that your ad dresswill always be accessible, regardlessof wh at machine changes go on be-hind the scenes.

We will attemp t to contact users whoseweb pages include URLs pointing atvirtual hosts. If you have any questionsabout constructing your URL, pleasesend em ail to our large system consult-ants at [email protected]

Since January 1999, UO colleges, insti-tutes, centers, and organizations withweb p ages on DARKWING have been ableto request a virtual hostname fortheir sites. This feature m akes site ad-dresses easier to remember.

For example, if the URL for yourdepartments web page is currentlysomething likehttp://darkwing.uoregon.edu/~german

you can ask Compu ting Center systemsstaff to create a virtual host for thispage w ith a less cum bersome addr ess,such as http://german.uoregon.edu

Selecting a Virtual HostnameThere are four imp ortant points to keepin mind when requesting a virtualhostname for your web site:

1. Virtual hostnames must not be cur-

rently assigned to another computer or

mailing list. To make sure the nameyou w ant is not currently being used by

another computer, type nslookup fol-lowed by the host name you wish tohave assigned , e.g.,

% nslookupgerman.uoregon.edu

If the nam e you entered is found , youwon t be able to request it.

2. The name you pick must be descrip-

tive. For example, the Comp uting Cen-ter would select cc.uoregon.edu orcomputing.uoregon.edu instead ofabacus.uoregon.eduor another obscurereference.

3. Virtual hostnames are used only

for web site URLs, not for email ad-dresses or any other pu rpose.

4. Personal accounts cant have virtual

hostnames. You must have a depart-mental account to host the web site. Ifyou need a departm ental account,please contact Connie French([email protected]).

Questions?For more information aboutvirtual hostnames, or to request one foryour d epartm ents web site, please [email protected]

ww w directory. If you want to usea single directory for both, you candefine an alias for the ww w directoryby typing

While this appear s to create two d irec-tories, there is really only on e copy ofeach file, and a change to on e copy willautom atically be mirrored in the other.

DocumentationYoull find FastTrack documentationlinked to both the Comp aq andNetscapeweb sites, e.g.,

Compaq: See Compaqs OpenVMSDocumenta t ion page a t http://www.openvms.digital.com:8000/
