Full Discussion: Su-only account with ssh capability and no interactive login
Operating Systems Linux Red Hat Su-only account with ssh capability and no interactive login Post 302884349 by rbatte1 on Monday 20th of January 2014 05:51:23 AM

Well, you could corrupt the password in /etc/shadow to prevent manual login. I'm a little unclear on whether you want the account to be able to use ssh to run something elsewhere or you want the account to be available from elsewhere to run commands locally.

If it is the former, then it will have ssh so long as it is on the path. If you want to set up some sort of service account for another server to drive work through, just set up a password-less SSH connection to this account.


Please elaborate on which of these you are wanting to do (or something else) so we can help you further. It seems like it might be a bit of both.

chsh

CHSH(1)                                                            User Commands                                                           CHSH(1)

NAME

       chsh - change login shell

SYNOPSIS

       chsh [options] [LOGIN]

DESCRIPTION

       The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change
       the login shell for her own account; the superuser may change the login shell for any account.

OPTIONS

       The options which apply to the chsh command are:

       -h, --help
           Display help message and exit.

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.

       -s, --shell SHELL
           The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.

       If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new
       value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks.

NOTE

       The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser,
       and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh
       in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell
       back to its original value.

FILES

       /etc/passwd
           User account information.

       /etc/shells
           List of valid login shells.

       /etc/login.defs
           Shadow password suite configuration.

SEE ALSO

       chfn(1), login.defs(5), passwd(5).
