help: some shell can not run su command?

ferry_4 — Thu, 23 Feb 2006 04:33:07 GMT

modify user's login shell through edit /etc/passwd ,not SAM. There is ok to telnet to the machine for these users, but they can not run su command. the error message is following:
/usr/lib/dld.sl: Can't open shared library: /usr/local/lib/libcom_err.sl
/usr/lib/dld.sl: No such file or directory
But these user can run su command through xwindow.
What's the reason? How to solve the problem?

Hi Ferry,

What is your SHLIB_PATH and LD_LIB_PATH ? Try to check from telnet,

# ldd `which su`

hi senthil,
normal user's su: /usr/bin/su
question user's su: /usr/local/bin/su

I can't imagine why there would be a "su" in /usr/local/bin unless you've been hacked. I would get rid of it.

Hi,

There shouldn't be any question user's su: /usr/local/bin/su .. Change it to /usr/bin/su

Tt's very surprising that su is ok in xwindow session which su at /usr/local/bin/su , but su is error in telnet session which su at /usr/local/bin/su.
It's ok if I type /usr/bin/su to run su command.
What's the order of the $PATH search?

Hello,

Just check PATH variable..

# echo $PATH and check the order in both X and telnet session.

Hi ferry,

Just make sure, in the file /etc/PATH file /usr/bin directory appears before /usr/local/bin.

Or work with the $PATH variable in /etc/profile file till "which su" command in both xwindow and normal telnet session yields the same result namely, /usr/bin/su

Try to change the PATH variable configuration. IT will get the binaries based on that. Change the configuration with /etc/profile as,

export PATH=/bin:/sbin:/usr/bin:/usr/sbin: like that but. /usr/local/bin has to come after /usr/bin. Try to see /etc/PATH file also.

If you have not explicitly configure DTSOURCEPROFILE=1 /etc/profile file is not read.
