How should i disable rsh remote shell in Hpux

Santhosh_Mani — Tue, 26 Jun 2018 13:14:35 GMT

I am trying to comment the remsh line in /etc/inetd.conf like #/usr/bin/remsh

And then i tried rsh its connecting because that is restricted shell.

Eventhough am commenting in /inetd.conf its connecting the remote connection.So how to avoid remote shell connection.

And what is the relation between rsh and remsh.

Becasue after disabling in inetd.conf also its connecting.

Please read the man pages for remsh, remshd and rsh.

From the remshd(1M) man page, it seems that you might need to comment out 2 lines in inetd.conf, one beginning with "shell" and the other with "kshell". After this, I suspect you would have to restart inetd, like

/sbin/init.d/inetd stop
/sbin/init.d/inetd start

On HP-UX, "rsh" is "restricted shell" and "remsh" is "remote shell". On other UNIXes, "rsh" is "remote shell". Otherwise, rsh is not related to remsh.

To disable all r* commands in HP-UX you must comment out these 3 lines in the /etc/inetd.conf:

login        stream tcp nowait root /usr/lbin/rlogind rlogind -B /etc/issue
shell        stream tcp nowait root /usr/lbin/remshd   remshd
exec         stream tcp nowait root /usr/lbin/rexecd   rexecd

Once you have done that you can force inetd to reread the /etc/inetd.conf configuration file by issuing the command:

# inetd -c
