Some of you have had problems recently with accessing the lab computers. Below is an email from the PHAS IT dept about this
If students login Linux computer, they may experience “Failed to start session” error and couldn’t login Linux. Here is the solution:
1. Press Ctrl+Alt+F3 switch to terminal window and login with their PHAS account
2. Rm .Xauthority file
3. Press Ctrl+Alt+F7 to login GUI interface to see if it fixes the problem
4. If it fixes the problem, press Ctrl+Alt+F3 again, type exit to exit the terminal window
5. If the student still couldn’t login, switch back to Ctrl+Alt+F3 terminal again
6. Mv .profile .profile.old, mv .login .login.old
7. Press Ctrl+Alt+F7 to login GUI interface, it should work
Hello All,
About the login problem, the student has to make sure they have the
correct password, if they forgot the password, they can come to
Hennings 203C to reset the password.
About saving files, basically, we don't let user save anything on the
local computer, when they login the computer, their home directory
should be mounted automatically, they should save everything under
their home directory.
About the permission issue, it was caused by a Group Policy update I
did last summer. I only tested to make sure all the programs are
running OK, but somehow the group policy block user from open folders
on the Desktop. I still need to find out which program the open folder
action use, and then put it on the allow to run program list.
But for now, I switch it back to use the old Group Policy, which will
redirect all the Ugrads accounts' Desktop (c:\progs\Desktop) and
Programs (c:\progs\Programs) folder to the same location. Under this
policy, the students couldn't open Desktop folder as well, but they
can navigate through the Start->Desktop->SubFolder, and then open the
files under the subfolder.
There are two reasons I want to use the new group policy:
1. More secure, only allowed programs can run, so it will prevent the
user from doing any damage on the computer.
2. Easy to manage, sometimes after the software update, I forgot to
create new shortcuts under c:\progs\Programs folder, then the student
will not be able to access the software.
I will run more test on the new group policy and deploy it when it's
fully tested.
