n\u00fctzlich f\u00fcr LDM_AUTOLOGIN : ltsp-shutdown.desktop<\/a><\/p>\n

LDM_GUESTLOGIN \u00e4hnlich ist wie LDM_AUTOLOGIN aber mit der zus\u00e4tzlichen M\u00f6glichkeit sich mit seinem eingnem Namen anzumelden.
\nDefault username ist der Name des Terminals (ltsp20,ltsp21, …)<\/p>\n

\/home\/ltsp20 usw. werde nicht automatisch aufger\u00e4umt.
\nEine L\u00f6sung daf\u00fcr:
\n[Ltsp-discuss] Guest sessions<\/a><\/p>\n

Create \/opt\/ltsp\/i386\/usr\/share\/ldm\/rc.d\/S00-guest-sessions, with the
\nfollowing contents:<\/p>\n

\ncase “$LDM_USERNAME” in
\n guest*)
\n ssh -S “$LDM_SOCKET” “$LDM_SERVER” ‘cd; rm -rf .* *; rsync -a \/etc\/skel\/ .’
\n ;;
\nesac\n<\/p><\/blockquote>\n

Save and run `sudo ltsp-update-image`, if you’re using NBD.<\/p>\n

That’s it, now all user accounts where the username starts with
\n“guest*”, will have their documents and settings erased on login.<\/p>\n

alkisg: Although that rm -rf should really be find . -delete<\/em><\/p>\n
