Announcements from the Bulletin, Today, Notification-L

11/26/03, Science Direct Decision
In consultation with faculty, the library has decided to not participate in the new three-year contract for access to Science Direct. There were many factors that went into this decision, and a summary of the key points along with links to additional resources will be found at www.macalester.edu/library/misc/.

A recently published article in Change identifies some key critical issues in scholarly publishing which are also a factor in this decision. A link to a copy of "The High Costs of Scholarly Journals," Change, November/December 2003, p. 10-19 is available on e-reserve at www. macalester.edu/eres/info10-01/info10c.pdf. If you have questions or comments about this decision, please contact Terri Fishel, x6343 or Dani Roach, x6703. [Bulletin, also 12/1]

11/23/03, E-Mail Server Upgrade Status
The second attempt/part of upgrading the mail server was successfully completed yesterday, November 22, at around noon. The e-mail server is now running on a newer, faster computer which also has more memory. This should make for a more responsive e-mail system.

There are a couple of auxiliary tasks which need to be done to the new mail server which won't happen until sometime this week or next. They will probably require a reboot. We will send out advance notice of when this will take place. [Notification-L]

11/21/03, SpamAssassin Configuration Documentation Released
As promised in today's Bulletin, documentation on customizing SpamAssassin with our homegrown Configuration tool is now ready for your use. As noted in the Bulletin, SpamAssassin does NOT discard any e-mail: it simply marks messages that look like spam by placing the tag "[***SPAM***]" in the Subject: field. Most users will not need to make any changes to their SpamAssassin configurations, but for those who wish to do so, we have developed tools and documentation so that you have that option.

There are three flavors of the SpamAssassin Configuration tool: one for Windows (all versions), one for Mac OS 9 and one for Mac OS X. These may be downloaded from the CIT software page at http://www.macalester.edu/cit/software/; look on the right side of the page and scroll down to "SpamAssassin Config."

The documentation for these tools may be found on CIT's documentation page at http://www.macalester.edu/cit/docs/xplatform/mulberry3 /spamassassin.pdf.

If you have questions about SpamAssassin, the SpamAssassin Configuration tools, or the documentation on these tools, please contact the Help Desk at x.6525. Do not reply to this message. [Notification-L]

11/21/03, Reminder: E-Mail Server Upgrade Tomorrow
This is a gentle reminder that the College's e-mail server upgrade will be completed tomorrow, Saturday, November 22. All e-mail service will be taken down beginning at 8:00 AM so that the upgrade can be performed. We expect to be done that afternoon, but we can't give an exact time when the mail server will be available again. You can call the Help Desk at x6525 for updates on the mail server status. Mail coming in to campus will be held on the machine that scans incoming messages for viruses until the main mail server comes back up, so no incoming messages will be lost. [Notification-L]

11/21/03, Taking Two Big Bites Out of Spam!
On October 9, with the blessing of the Information Services Advisory Committee, CIT announced our two-pronged plan to help control spam in college e-mail (see http:// www.macalester.edu/infoservices/planning/spam.html). On November 6, we put the first half of that plan into action by passing all incoming e-mail through a filter created and updated by SpamHaus (http://www.spamhaus.org/). This filter stops all e-mail coming from a handful of known spammers, whose businesses are built around sending nothing but spam (and plenty of it). As SpamHaus notes, fewer than 200 spam outfits account for 90 percent of spam on the Internet - so blocking mail from these outfits is virtually guaranteed to prevent only spam. Since the filter has been in place, approximately 2,900 spam messages per hour have been prevented from entering our e-mail system.

The second half of our spam solution was announced November 19. This is SpamAssassin (http://www.spamassassin.org), a tool that resides on our e-mail server. While SpamAssassin does NOT block mail, it compares incoming messages against an evolving list of criteria that tend to distinguish spam from legitimate messages. E-mail messages which score above a certain level of "spam similarity" have the text tag "[***SPAM***]" placed in the subject line of the message, but the message is still delivered normally to your account. By doing this, you get a warning that a message looks like spam, but there is no danger that the message will be thrown away unless you delete it. The ultimate responsibility for deciding whether a message is spam or not rests with you, the recipient.

To reiterate crucial points: the only messages blocked by SpamHaus are those coming from a small number of known spammers who send nothing BUT spam. Likewise, while SpamAssassin marks suspicious messages as spam, it does NOT delete or block any messages. Each individual at Macalester controls his or her own e-mail.

SpamAssassin may be configured to your individual specifications: while you do not need to take any action, you may change many of SpamAssassin's settings. Customized copies of the SpamAssassin Config Maker tool are available for Windows (all versions), Macintosh OS 9 and Macintosh OS X. These may be downloaded from the CIT software page at http://www.macalester.edu /cit/software/; look on the right side of the page and scroll down to "SpamAssassin Config." We have released this tool now due to high demand from campus. Please be aware that documentation for the SpamAssassin Config tools is not yet available, but is in the final stages of being created. If you are not sure of your options using the SpamAssassin Config Maker tool, please wait for the documentation (which will be announced as soon as it is ready). [Bulletin, also 11/24, 12/1]

11/21/03, Return of the Languages Lounge
An old friend is back in the Humanities Resource Center. Tom Browne has re-configured the southeast corner of the HRC with couches, chairs, tables and lamps for use as a languages reading and study lounge. All are welcome. This re-creates an informal reading area that had been part of the Humanities floorplan years ago, but which was lost in subsequent additions to, and expansion within, the building. Please stop by! [Bulletin, also 11/24, 11/26]

11/21/03, Administrative System Planning
Macalester has embarked on a process to evaluate alternatives to our current central administrative data system, Jenzabar/CARS. If this analysis shows that a better choice is available, we may then make a decision to purchase a new system and convert over to it. Most aspects of College business will be affected, including payroll, academic records, billing, purchasing, class registration and many others. Therefore, this choice will significantly impact every person at Macalester! A host of background documents, including criteria, timelines and notes on potential systems, may be found on our central Admin Planning Web pages, beginning at http://www.macalester.edu/ adminplan/. We encourage everyone to examine this information and stay abreast of the process. [Bulletin, also 11/24, 12/1]

11/19/03, E-Mail Server Upgrade Rescheduled
We have scheduled the completion of the mail server upgrade for Saturday, November 22, beginning at 8:00 AM. We expect to be done that afternoon, but we can't give an exact time when the mail server will be available again. You can call the Help Desk at x6525 for updates on the mail server status. Mail coming in to campus will be held on the machine that scans incoming messages for viruses until the main mail server comes back up, so no incoming messages will be lost. [Notification-L]

11/19/03, SpamAssassin and Spam Configuration Utility
We have started using SpamAssassin on all e-mail from the Internet. SpamAssassin is used to identify spam. It does not discard any e-mail it thinks is spam. It still delivers it to you, but just prepends "[*** SPAM ***]" to the subject line of any message it thinks is spam.

Repeat: It does not discard any e-mail it thinks is spam. It just tags it.

We've written a home-grown program for customizing SpamAssassin. Using it, you may:


The SpamAssassin configuration utility for Mac and Windows may be downloaded from http://www. macalester.edu/cit/software/index.html.

With its filtering capabilities, Mulberry may be configured to auto-delete or auto-file suspected spam based on the tags SpamAssassin adds. Read about Mulberry's filters here:
http://www.macalester.edu/cit/docs/xplatform/ mulberry3/mulberry3filters.pdf.

SpamAssassin's home page is here: http://www.spamassassin.org.

About PureMessage. Many people have asked about PureMessage. PureMessage is another spam tagging program we had implemented just recently. It would prepend the subject line with "[PMX: XXXX...]". We've had ongoing problems with the PureMessage process just quitting for no apparent reason, causing all inbound (from the Internet) e-mail to not get delivered. Due to this problem, it is currently shelved indefinitely. [Notification-L]

11/15/03, Mail Server Upgrade
There's good news and bad news about the mail server upgrade. The bad news is that we discovered some hardware problems, and were unable to complete the upgrade. The good news is that some parts of the upgrade were completed successfully, and you should see some performance improvements in e-mail. As soon as we can resolve the problems, we will reschedule a time to complete the upgrade. [Notification-L]

11/14/03, 4:10 PM: Countdown to Upgrade
A reminder that e-mail service goes down for a server upgrade at 4:30 PM today.

A reminder we will install a new e-mail server this evening and that means interruption of e-mail service beginning at 4:30 PM today. While this was announced previously, the lead time is shorter than we strive for and reflects the urgency of improving reliability of the service as soon as possible. Because of preparatory work, the install would take a few hours under ideal circumstances. Since "ideal circumstances" are not usually what you get in this business, count on restoration of service by Saturday morning. Of course, we regret the inconvenience to you and will make the interruption as short as possible. [Notification-L]

11/14/03, New E-Mail Server to be Installed - 4:30 PM Today
The new e-mail server will be installed this afternoon, Nov. 14. All college e-mail service will be down beginning at 4:30 PM. It is expected that service will be restored, running on the new server, the morning of Saturday, Nov. 15. Explanatory bulletins will be recorded on the Help Desk's voicemail system as needed, and can be accessed by calling x6525.

E-mail messages from off-campus correspondents cannot be delivered here while the Macalester mail server is offline. While most other e-mail servers around the world will notify their senders that Macalester-bound messages could not be delivered during the downtime, a few may not do so. If you are expecting an important communication, you may wish to contact the intended sender and notify him/her of the downtime. [Bulletin Flash]

11/14/03, 10:00 AM: E-Mail Fix
A reminder we will install a new e-mail server this evening and that means interruption of e-mail service beginning at 4:30 PM today. While this was announced previously, the lead time is shorter than we strive for and reflects the urgency of improving reliability of the service as soon as possible. Because of preparatory work, the install would take a few hours under ideal circumstances.

Of course, we regret the inconvenience to you and will make the interruption as short as possible. [Notification-L]

11/14/03, E-Mail
E-mail service has been inconsistent recently and the slow-downs have interfered with our work. The reason is an unfortunate delay in delivery and installation of an upgraded server from Sun Microsystems. The good news is our new e-mail server is configured and ready to be installed. This installation will require a period of downtime while the old server is removed, the new one is put in, data are migrated and the system is tested. All College e-mail service will be down beginning at 4:30 PM Friday, November 14. It is expected that service will be restored, running on the new server, the morning of Saturday, November 15.

Recognizing how critical e-mail is to the College community, please note that the installation could take longer - another reason to perform it over a weekend. Explanatory bulletins will be recorded on the Help Desk's voicemail system as needed, and can be accessed by calling x6525. [Bulletin]

11/14/03, More or Less Spam
While the proportion of e-mail that is spam is increasing, we are following through with previously announced plans to cut down the amount that reaches our desktops. The first phase of the plan is spam-blocking at the server (before it reaches you) based on information from SpamHaus (www.spamhaus.org). Over 150,000 spam messages were blocked in the first four days of this action or an average of 1,600 messages per hour. [Bulletin, also 11/17, 11/19]

11/14/03, Don't Trust That Diskette!
As the semester progresses and students begin to work on larger papers and other assignments, the Help Desk sees more students coming in with damaged or worn-out floppy and Zip diskettes. Repeatedly, we hear, "But all my work is stored on that one diskette and I don't have a backup!" We'll do everything we can to recover data from diskettes when this happens, but the outlook is usually grim. You can prevent this problem by saving copies of important files to network drives and to redundant media - such that if one diskette dies, you have the files on other diskettes and drives. Also, keep your diskettes clean and protect them from damage: carry them in a hard case, rather than loose in a backpack. Since your data is critically important, protect it now! [Bulletin, also 11/17, 11/19]

11/14/03, Sponsoring An Event for Off-Campus People?
No matter how well you publicize, our switchboard is called asking who, what, when and where. Please share the specifics of your event with Colleen Nelson, our switchboard operator at x6000. Any information provided is greatly appreciated. [Bulletin, also 11/17, 11/19]

11/13/03, New E-Mail Server To Be Installed
After significant delays on the vendor's part, our new e-mail server is configured and ready to be installed. This installation will require a period of downtime while the old server is removed, the new one is put in, data are migrated and the system is tested. All College e-mail service will be down beginning at 4:30 PM Friday November 14. It is expected that service will be restored, running on the new server, the morning of Saturday November 15.

Recognizing how critical e-mail is to the College community, please note that the installation could take longer - another reason to perform it over a weekend. Explanatory bulletins will be recorded on the Help Desk's voicemail system as needed, and can be accessed by calling x.6525.

11/13/03, DHCP Server Down Last Night
Last night, from about 5:00 PM to about 7:30 AM this morning, the DHCP ('Dynamic Host Configuration Protocol') server was down. The DHCP server is what assigns network addresses to computers, and without a network address, a computer cannot access the network.

Any computers that were already on would have not been affected, but anyone trying to startup their computer during that time would not have been able to access the network.

DHCP is an acronym for 'Dynamic Host Configuration Protocol'. You can read about it here: http://rfc.dnssec.net/rfc2131. txt. [Notification-L]

11/05/03, Internet Slowdown
Wednesday, November 5: This afternoon we experienced severe slowdowns in our Internet connectivity because of a denial of service attack. The attack began at around 3:00 PM, and ended shortly before 4:30 PM. [Notification-L]

10/31/03, Computer Peripherals and the Micro Fund
Many items that formerly were thought to be high-end equipment have become generic. These include the laptop mouse, port replicator, extra monitors, external drives of various sorts, etc. Maintaining a sustainable Micro Fund to upgrade staff and faculty computers means that departmental T.E.M. budgets should support these purchases. Please keep that in mind while putting together your budget proposal for 2004-05. [Bulletin (also 11/3, 11/5)]

10/31/03, Computers and the Micro Fund
Our policy of supporting one computer per faculty and staff member, plus public labs, plus others as needed has netted us a proportionately high population of computers that the College would struggle to sustain long term. After consultation with our Information Services Advisory Committee and others, we are prioritizing upgrade investments to computers that originally were purchased through the Micro Fund. Computers purchased through departmental funds, grants, and personally administered college funds must be placed in second priority. See the computer procurement policy at http ://www.macalester.edu/infoplan/archived/procurement.html. [Bulletin (also 11/3, 11/5)]

10/31/03, E-Mail
We plan an upgrade of the e-mail server as soon as technical preparation is done and a time is found that minimally disrupts College work. E-mail performance of both the old and new servers depends on cooperation in keeping Inboxes to a minimum size (under 5 Megabytes). This has little to do with availability of storage space but much to do with throughput of the server, which must sort through all Inboxes to open one of them. You can also help performance at your end by closing your mailboxes other than your Inbox before logging off. Your computer then has an easier time opening your account when you log in. Performance also is helped by cleaning out your "Sent" mailbox regularly, if you use one. [Bulletin (also 11/3, 11/5)]

10/31/03, Laptop Loans Temporarily Suspended
The Help Desk's pool of PC and Macintosh laptop computers for short-term loan to faculty and staff has been very popular. Unfortunately, many borrowers have kept computers beyond their due dates or have been negligent in caring for the gear. Through theft and loss, at least one computer and multiple peripheral items have disappeared, and some of those that remain are damaged. It is necessary for us to temporarily suspend the loan of laptops from the Help Desk while we work to repair the damaged items and secure the return of tardy equipment. [Bulletin (also 11/3, 11/5)]
