/bin/ksh "not found" for no-root user
Olivier Gobert
Hello
Have a problem that drives me crazy.
On a RS6K 37T with AIX 4.1.4, only root can log on the system.
With root account, everything's OK but user with UID != 0 can't log in.
Whith rsh/rlogin the message is "/bin/ksh : permission denied"
With telnet "3004-009 Failed running login shell."
Of course permissions are OK
Something strange : I have the "Failed running login shell." whatever the
l.s. is ( /bin/sh, /usr/bin/ksh, /usr/local/bin/tcsh ... )
When I log in as root and "su" to an other user, the message is "Cannot set
process environment."
I have run the "su" in trace mode. Here's the last lines of the trace :
106 su 6.275504 dispatch: cmd=su pid=18296 tid=13697 priority=63
old_tid=14003 old_priority=60 CPUID=0 [513 usec]
107 su 6.275504* lookuppn: /bin/ksh
107 su 6.276177 lookuppn: file not found
Off course /bin/ksh is at the right place ( and /bin is a symbolic link to
/usr/bin and /usr/bin/ksh is a physical link to /usr/bin/ksh everything
sounds OK )
I even reboot in single mode and run "fsck" on / an /usr. fsck also say "OK"
but the problem is still there...
Any help will be greatly appreciated

Do non-root users have execute permission on either /bin or /usr/bin?
Check this, it can cause the file not found.

Yea, first thing I've checked :
root@bofix: >ls -l /bin/ksh
-r-xr-xr-x 4 bin bin 230148 Sep 20 1995 /bin/ksh
root@bofix: >ls -ld /bin
lrwxrwxrwx 1 root system 8 Aug 21 19:13 /bin -> /usr/bin
root@bofix: >ls -ld /usr/bin
drwxr-xr-x 4 bin bin 10752 Aug 21 19:17 /usr/bin
root@bofix: >ls -ld /usr
drwxr-xr-x 22 root bin 512 Aug 20 17:46 /usr
root@bofix: >su - ogobert
Cannot set process environment.
Any clue ?

You might also want to check the chmod settings of your /etc/passwd
file; should be -r--r--r-- . I've troubleshooted similar problems in
the past, which have turned out to be sysadms changing passwd privledges
to -r--------!

Find a solution.
In the AIX install CD-ROM, I've found a package called :
"bos.rte.shell.usr.4.1.4.0"
It contains all the shells ( sh, csh, ksh ) + some commands ( eg : awk )
Re-install it with -f ( force ) option.
Now everything is OK
It's a bit strange 'cause it also solves the problem with tcsh which is not
in the package ?!?
Thanks for your help

Look at the permissions of your root filesystem, there has to be the
execute permission for "others". I assume your root directory looks
like "drwxr--r--" or "drwxr-w---", it has to read "drwxr-xr-x".
