This is a critical situation for me. can anyone help?

Shalom,

Check actual existence and permissions of this file:

/usr/bin/sh

Did you perhaps change the root shell in /etc/passwd ? that is a big thing never to do.

The file exist and the permission on it is okay. cksum was good. The root shell in passwd is still /sbin/sh

tstbe1# /var/adm/sw>more /etc/passwd
root:Je4X1JV.CyFLs,O06U:0:3::/:/sbin/sh
daemon:*:1:5::/:/sbin/sh
bin:*:2:2::/usr/bin:/sbin/sh
sys:*:3:3::/:
adm:*:4:4::/var/adm:/sbin/sh
uucp:*:5:3::/var/spool/uucppublic:/usr/lbin/uucp/uucico
lp:*:9:7::/var/spool/lp:/sbin/sh
nuucp:*:11:11::/var/spool/uucppublic:/usr/lbin/uucp/uucico

the command even failed if run from the prompt

tstbe1# />sh
sh: sh: Execute permission denied.

Hi:

# sh: /usr/bin/sh: Execute permission denied.

So what are the permissions for '/usr/bin/sh'?

They should look like:

# ls -l /usr/bin/sh
-r-xr-xr-x 2 bin bin 587360 Nov 14 2007 /usr/bin/sh

Regards!

tstbe1# />ls -l /usr/bin/sh
-r-xr-xr-x 2 bin bin 204800 Oct 21 2003 /usr/bin/sh

The /usr/bin/sh binary might not be a valid one. What is the output of the commands "file /usr/bin/sh" and "what /usr/bin/sh"

Hi

126 Command invoked cannot execute Permission problem or command is not an executable

Check another machine and note JRF's response. The byte counts totals are different.

Copy from another machine or reinstall.

[Dennis Handly]

Are you on a PA or Integrity system?
TTr's suggestion of using file(1) may indicate you restored the wrong one on your system.

>Michael: The byte counts totals are different.

Well, that's because it could be an older OS version of patch level. And JRF said "like". :-)

The probelm is resolved.

The problem was due to the etrust application installed by the security group in my environment. Once the etrust daemon was stopped, everything as back to normal.
Thanks you all for your input.
