Re: Help Please: KDE refuses login to any client (WS incl.)

[Christian Andersson <ca@ofs.no>]

Hi there, one of the most common thing I've read about and experienced 
when users cannot log into kde on the thin client is that the different 
partitions are full.

If KDE cannot write to the /tmp directory on the thinclient server it 
cannot log in, what you need to check here is if the /tmp directory is 
full, you can do that when running the "df -k" command.

if it is /tmp that is full, then you need to remove some files from that 
directory, (in an erlier version of skolelinux /tmp was using the tmpfs 
filesystem which stores all fiels in memory,rebooting the server will 
then clear the /tmp directory completely, but this I do not advice)

if it is not /tmp that is full it can also be the mount that holds the 
home directories that is full. in an earlier version it was 
/skole/tjener/home0 or something like that. this mountpoint resides on 
the file/ldap server.

so if you run "df -k"  when logged in to the  fileserver (or the 
thinclient server) you will find out if the "home" mount has bbeen 
filled up.

if it has been filled up, then there are 2 things you can do.
1: remove files (not very good)
2: increase the size of that partition.

I don't have the reciepe at hand on how to increse the size of that 
partition, but I know other persons in here do have it...
