Shell type on trusted system

Ashish Jain — Thu, 18 Jul 2002 09:24:58 GMT

If I specify a non defualt shell for a login account on my HPUX 11.0 trusted system, I get an error saying this shell not allowed. Any clues where can I make an entry for this shell?

There is a a file /etc/shells. In this file you have to mention al shells you like to use in /etc/passwd or manually, like

/sbin/sh
usr/bin/ksh
.
.

Good luck

Hi:

...and one word of caution: *never* change the default shell for 'root' from '/sbin/sh'. If you do, you will end up with an unbootable system.

Hi:

If 'etc/shells' doesn't exist, or isn't readable, then the following list of valid shells is assumed:

/sbin/sh
/usr/bin/sh
/usr/bin/rsh
/usr/bin/ksh
/usr/bin/rksh
/usr/bin/csh
/usr/bin/keysh

This is documented in 'man 3 getusershell'.

Therefore, create an /etc/shells file. Make its permissions 444 owned by 'root'. Add the above standard shells and add your chosen shell to the list.

Regards!
