[Ltsp-discuss] Volatile home directory (Jan Kowalsky)

[Angus, Jackie]

I've done something like this. In /usr/share/ldm/rc.d/S00-guest-sessions

I put this line

case "$LDM_USERNAME" in
WipedUserHere*)
ssh -S "$LDM_SOCKET" "$LDM_SERVER" 'cd; rsync -av --delete /etc/backups$
;;
esac

then I keep copies of the the home directories in /etc/backup

When the LTSP client boots it syncs the current directory with it's matching backup dir in /etc/backup
This has been working quite well.

Hi g,

we have the same question in one of our networks. We provide guest accounts.

Hi all.
I'm trying to obtain a configuration for LTSP (no fat client) in which
all modifications made by the users on their home dir are discarded
before logout.
In other words, I would like every user find the same configuration for
desktop and personal settings each time he logs in. I would prevent
modifications from an initial configuration I made for users.
Of course the whole system can't work with read-only home dirs. Too easy :)
I tried understanding how to avoid sshfs mount of home dirs, but just
specifying a generic
CONFIGURE_FSTAB=true
FSTAB_1="tmpfs /home/ tmpfs
nodev,nosuid,size=512m,mode=777 0 0"
in /opt/ltsp/amd64/etc/lts.conf didn't help
I tried commenting out the line with sshfs in
/opt/ltsp/amd64/usr/share/ldm/rc.d/X01-localapps
manually mounted a user's home tmpfs dir on thin client before user
logged in, but no luck and the LDM restarted after hangup for a few minutes.
Does anyone faced with a similar goal to reach? Can anyone please point
me in the right direction?

well, we took a different approach. We simply use pam-scripts to create
home-dirs on login and remove them again on logout.

If there is a possibility to do this with tmpfs in ltsp this would be
nice. But be aware: a user only has to download or copy any big file and
your ram will not be sufficient.

Regards
Jan
