chsh problem

[Karthik S S]

Hi,

When I try to change the default login shell it gives the following error,

$ chsh /usr/bin/ksh
Can't bind library /usr/lib/libpwpauth.sl: Unresolved external.
chsh: you have no password file entry
Usage: chsh name [ shell ]

What could be the problem?

OS is 10.20 running on 712 workstation.
Pl. help

Thanks
Karthik

Hi,

$chsh myusername /usr/bin/ksh

should work.

Hi,

U.SivaKumar is right. I actually think that chsh will not work on a user who is currently logged in, but I'm not sure. In that case, use vipw to edit /etc/passwd.

BTW, never set the root user's shell to /usr/bin/ksh, as your system won't come up after a reboot....

Regards,

Vincent

Even that is not working,


$ chsh sysadm /usr/bin/ksh
Can't bind library /usr/lib/libpwpauth.sl: Unresolved external.

here sysadm is the user name. I tried the same command on different machines where it works just fine ....

Thats right karthik, go through the man pages of chsh. It requires username whose shell u want to change.

Then you are missing setuid bit on /bin/chsh executable.

Do this as root.

#chmod +s /bin/chsh

Hi

setuid is already set. But even as root it is giving me the same error. I know that the easy way is to manually edit the passwd file but, I wanted to know what exactly is the problem.

When I run this as root,

# chsh sysadm /usr/bin/ksh
Can't bind library /usr/lib/libpwpauth.sl: Unresolved external.

Pl. help
