My best guess is that /usr/bin/sh is corrupt or you have done something dumb like made bash the shell. Root uses a statically linked version of the POSIX sh, /sbin/sh so it can run standalone but the other users execute a dynamically linked version. I would first do an "ls -l /usr/bin/sh" and then a "file /usr/bin/sh". If those look ok, as root execute /usr/bin/sh and see what happens. You could have permission problems on /usr/bin/sh or one of the libraries it links to. You could also have a bogus entry in /etc/shells.

"su to normal user its su: noshell "

what shell is the "normal user" noted above assigned in the passwd file?

hi when i su from root to


ri004361:99/o7MN.0Pm86:223:22::/home/ri004361:/bin/csh

[achyuth]

histephenson,

soory for the wrong report in my previous reply

when i do /usr/bin/sh
pwd

it point to "/" not to /tmp

[OldSchool]

ok, so the user that has "no shell" is attempting to run the c-shell...so

what do "ls -l /bin/csh" and "file /bin/csh" report?

[achyuth]

hi,

ls -l /bin/csh
-r-xr-xr-x 1 bin bin 155648 Nov 2 16:00 /bin/csh

file/bin/csh
/bin/csh: PA-RISC1.1 shared executable dynamically linked
