i did a quick look through of the list archives and didn't see any mention of
this, so i figured i'd send it in. i have some users that are using tcsh, and
they have been running into problems where when they run csh or tcsh shell
scripts. when they try to run a shell script, the system tries (and fails) to
regenerate all their ssh keys in their CWD (the only time this doesn't happen
is if they run in their home directory). i traced the problem to the
ssh-oscar.csh script, which apparently has a problem on the line that starts
"set home=`echo $home ..`" where it was zeroing out the value of $home in this
context, and home was being set to CWD. i tested this type of resetting of a
variable to a parsed version of itself in tcsh/csh outside of this script, and
got the same results. i have only verified this on CentOS systems (i have
checked both 5.1 and 5.2) with OSCAR 5.1b2.
anyway, the simple fix for this turned out to be:
--- ssh-oscar.csh.orig 2008-01-06 15:47:37.000000000 -0500
+++ ssh-oscar.csh 2009-04-06 09:20:29.000000000 -0400

if ( "$user" == "nobody" ) then
echo Not creating SSH keys for user $user
else if ( -d "$home" ) then
figured i'd send it along in case anyone else was having similar problems.
