To add a new node (say cdf5) to the pbs queue on cdf30, start the qmgr program and issue this command:
c n cdf5 np=2,properties=fast
Only put the np=2 part in if the node has dual processors.

This command will tell you which process is using a particular tcp port. In the case of the example, port 80, the httpd port.
lsof -i tcp:80
I wrote a couple of perl scripts that run on each machine and find out how many files each user has on each data disk. The way this works is that there are two scripts that run on each machine. First is gen_disk_listing, which is just a find command that generates a list of all the files on the data disks. Second is find_data_disk_hogs which separates the files by owner. The last script is run on cdf which creates a webpage from all the data gathered.
When applying thermal compound to a cpu, make sure that you install it as thin as possible. Ideally, drop about a pea-sized dollup in the middle of the cpu and spread it all over the cpu top. Don’t get any on the underside.
If you apply too much, as I did, the response was that the machine would start up and then emit a high-pitched continuous beep for as long as the computer was on.
I upgraded a machine with a radeon 7000 video card to FC5. The installation was easy and it appeared as though everything worked. However, after logging in as any user, the entire machine would hang. Reboot, login and it would hang again. Solution: Edit the file /etc/X11/xorg.conf and look for a line that reads:
Load “dri”
Comment out this line and reboot.
Our hp800 ps printer is a postscript plotter that is very slow when printing a postscript file. On windows, print speeds increase dramatically if one prints to the HP-GL2 printer queue and not the postscript queue. Unforrtunately, Mac OS X does not have an HP-GL2 driver. The only driver is available is the postscript driver. Which means that printing from a Mac takes forever. Easiest solution is to take the file to the windows machine and print it there. I’ll have to watch for any new drivers from HP for this printer.
