Q. I’ve HP-UX installed on my HP UX UNIX server. But I’m not able to start or restart the OpenSSH ssh server. How do I stop or restart sshd under HP-UX?
A. HP-UX Secure Shell uses Pluggable Authentication Module for password authentication. Server configuration file is located at /opt/ssh/etc/sshd_config.
/sbin/init.d/secsh {start|stop}
/etc/rc.config.d/sshd
Type the command:
# /sbin/init.d/secsh stop
Type the command:
# /sbin/init.d/secsh start
Both rsh or rlogin prompt for a password. All you need to do is open /etc/hosts.equiv file on host system and add entries for all hosts you would like use without password .
This file list of hosts and users that are granted “trusted” r (rsh/rloging) command access to your system without supplying a password.
$ cat /etc/hosts.equiv
Output:
job1.ha1.nixcraft.com job2.ha1.nixcraft.com job3.ha1.nixcraft.com
In above file job1, job2, job3 hosts can connect without a password.
Caution: R (rsh/rlogin) commands are very insecure if possible switch to secure shell (ssh). You can configure ssh so that is does not prompt for a password.
