  • Spamassassin server died

    One of our two spamassassin servers stopped working Saturday at about 9:00am and was not fixed until 8:00am Sunday morning. During that time about half of all email being sent to spamassassin was not being checked and was just delivered instead. So you probably saw a big rise in spam in the past 24 hours.…

  • Internet Bandwith Increase

    As of about 6:00pm tonight, our internet bandwith has doubled from 10M to 20M. It’s probably maxed out by the time I finish typing this, but oh well. Was good while it lasted 🙂

  • Solen rebooted

    In case you noticed everything screetching to a halt tonight around 7pm, solen had a kernel panic and had to be rebooted. About 20 minutes later, it was back up and running again.

  • Norelius and Complex at a gig too

    Norelius and Complex (North, Gibbs, and Sorensen) also just had their collective network connection to Olin increased from 100Mbit to 1000Gbit. File transfers and possibly on campus gaming should improve as a result. Unfortunately that does not mean the internet will be any faster. Though we did finally sign a contract that should double our…

  • International Building now at a gig

    The network connection for the International center bas been bumped up from 100Mbit/s to 1000Mbit/s as of about 11:30am this morning. Hope that makes some things a little bit faster.

  • SpamAssassin and Horde’s IMP

    —

    by

    Unfortunately due to the way that Horde’s IMP webmail system inserts the IP address that was used to connect to the it in the email headers it sends, SpamAssassin thinks those messages are coming from dynamic ip addresses. To help work around this issue, I modified our SpamAssassin rules such that any email sent via…

  • Horde Imp and Spamassassin

    —

    by

    doachs

    Unfortunately it looks like Horde’s Imp webmail system and SpamAssassin don’t agree on how to deal with dynamic ip addresses sending email. If you connect to a webmail system running running Imp and send a message using your home web browser on a cable modem connection, that ip address gets loged in the headers of…

  • Gibbs, Sorensen, North

    Gibbs, Sorensen, and North were down for about 3 hours from 5:15pm to 8:15pm due to a strange network problem. Some device in one of those dorms caused almost all of our network traffic on the res hall subnet to be very slow.

  • SpamAssassin Upgrade

    doachs

    After testing the latest version of Spamassassin on my account for the past few days, I have upgraded all our Spamassassin servers from 3.0.0 to 3.0.2. 3.0.2 includes a few bug fixes and other small enhancements. If anyone notices a drastic change in spam checking effectiveness, please let me know.

  • Squid on Fedora Core 3

    Due to the way SELINUX is setup on Fedora Core 3 ( FC3 ) I discovered that if you try to move squid’s cache directory, you must tell SELINUX that the new location is ok. To do that, use the following command: chcon -R system_u:object_r:squid_cache_t /directory/where/cache-is
