After upgrading to RHEL4, the program gnomecal was no longer present. The newer program was evolution, but it would not import the user-cal.vcf file from gnomecal. The solution was to install Sunbird (Mozilla’s calendar) and import the data there. Unfortunately, a direct import didn’t work. First the file user-cal.vcf was renamed to user-cal.vcs. This was then imported into Outlook. In Outlook, the calendar was then exported as a comma-separated file, which could successfully be imported into Sunbird.

We have a computer with an nVidia 7100GS video card and a Dell 1908FP monitor. The video card works fine after downloading and installing the driver from the nVidia web site. But the display only gives the choice of “800×600” or “640×480” resolutions. To get “1280×1024” resolution, edit /etc/X11/xorg.conf. Here are the relevant sections (info added is in bold):

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Monitor Vendor"
    ModelName      "Unknown monitor"

If a pbs job is unable to write to disk (usually a log file to the user’s home area), check the file /var/spool/torque/mom_priv/config and make sure that there’s a line for each SUBMISSION system that looks like this:

$usecp uct3-edge3.uchicago.edu:/ /
$usecp uct3-edge5.uchicago.edu:/ /
$usecp uct3-edge7.uchicago.edu:/ /

Then, if any changes were made to this file, restart pbs_mom.

Our mailman server is no longer archiving messages. I checked the permissions on some files and found that many were wrong. They can be fixed with /usr/lib/mailman/bin/check_perms -f, if this command is run as root.

This still hasn’t fixed our archive issue, but it looks to get me closer.
