It certainly wasn't the McIDAS installation since the user 'mcidas' does not have the permission levels necessary to change the ownership of other user's accounts. >I still can't log in as LDM properly, because my gnome-panel >settings got wiped out, and I don't know how to "start over" with a basic >panel so I can get things to work in that account. You mean that you can't login "graphically"? I just logged in as 'ldm' with no problems, but this was from an xterm. >Thankfully, the root >account seems to be OK. Any idea from your sysadmins on how to fix this? I would say ownership of one one or more files in the 'ldm' directory hierarchy. I noticed that a number of the files under ~ldm had 'ldm' as the owner, but 'bin' as the group ID. I changed this as 'root' with: <as 'root'> cd /home/ldm chown -R ldm:users * >After two hours of borking, I decided to make users the primary group for >LDM and McIDAS. But, McIDAS isn't saving the data anymore. Can you check >and see what I cam doing wrong? The problem was again one of 'ldm' and 'mcidas' not being in the same group, or, more correctly, of the ownership on McIDAS executables being still set as mcidas:ldm and not mcidas:users. I changed this in the same way as I did for the user 'ldm': <as 'root'> cd /home/mcidas chown -R mcidas:users * After changing the owner:group of all files in both ~mcidas and ~ldm (and all subdirectories!), I stopped and restarted your LDM. The McIDAS-XCD process are once again running. Hold on... As I was working on weather3 I noticed that the ownership of all files under /home/ldm would change from ldm:users to mcidas:users. I also noticed that the ownership of all files under /home/mcidas changed from mcidas:users to ldm:users. Are you making changes now, or is this some bizarre result of something run amok? So, question is how the permissions keep getting changed? >P.S. Try SSH'ing into weather3 directly now. It works, thanks. It was a real pain to have to SSH to weather2 and then to weather/weather3.
