[Pkg-ltsp-devel] Bug#490897: ldm: tcsh users unable to login]

[Daniel Nilsson]

Package: ldm
Version: 2:2.0.6-1~40.etch.0
Severity: important


After a lot of hours spent troubleshooting I have discovered that ldm (at least, 
could be other parts of ltsp as well) assumed that the user trying to login
is using as bourne shell in the server machine. 

For example, line 71 if src/sshutils.c of ldm:

    sshcmd[i++] = "LANG=C";

Here ssh is hardcoded to set an environmental variable using this syntax 
which is not compatible with tcsh syntax (env LANG=C would be needed in that
case). I tried changing the above but this only seemed to move the problem
somewhere else. If I create two new users on the server where one user is
using /bin/bash as login shell and one user is using /usr/bin/tcsh only the
bash user is allowed to login.

I'm on etch but I followed the directions here to install LTSP5:
