Hi:

First, you need to establish a 'hosts.equiv' or '.rhosts' file on both servers. See the manpages for 'hosts.equiv(4)' for this.

You will also want to make sure the '/etc/inetd.conf' has the 'login', 'shell' and 'exec' services enabled.

The manpages for 'remsh(1)' offer additional information for you.

Regards!

Hi,

I use .rhosts, it seems easier to setup then hosts.equiv. Make sure that the .rhost is in the home directory of the user.

The man pages for .rhosts is very good and will show you exactly how to set it up.

If you are at all interested in Sarbens Oxly, they kind of frown on this. If you setup your .rhosts completely, you can usually talk them out of it. So make sure that you not only have the system name but also the user name in the .rhosts.

Here is an example of a command

remsh hp1 -n "/sbin/init.d/sendmail stop"

Hi,

the script needs to be accessible on hostB when you execute it:
In this script fragment called from your sun
...
thishost=sun
hphost=hp
rsh $hphost /path/to/script/script
echo fini on $hphost
...
the pathname '/path/to/script/script' gets resolved on $hphost.

If this is not the case, you'll have to transfer this file to $hphost first and then call the requested interpreter (e.g. perl, ksh):
...
thishost=sun
rcp /path/to/script/script $hphost:/tmp
rsh $hphost 'ksh /tmp/script'
echo fini on $hphost
...

amonamon,

From 'man remsh':

The remote account name used is the same as your local account name, unless you specify a different remote name with the -l option. In addition, the remote host account name must also conform to other rules which differ depending upon whether the remote host is operating in a Kerberos V5 Network Authentication, i.e., secure environment or not. In a non-secure, or traditional environment, the remote account name must be equivalent to the originating account; no provision is made for specifying a password with a command. For more details about equivalent hosts and how to specify them, see hosts.equiv(4). The files inspected by remshd on the remote host are /etc/hosts.equiv and $HOME/.rhosts (see remshd(1M)).

So you should not be prompted for a password when you 'rlogin' or 'rsh'. If you are, ~/.rhosts is not configured correctly and/or you are not logging in as the proper user. You must fix this, as "no provision is made for specifying a password with a command". To log in as a different remote user:

# rsh -l -n

So in your script, you would put:

#!/usr/bin/sh
rsh hpux_server -l user1 -n /scripts/script_to_run.sh
echo "Done."

Note that '/scripts/script_to_run.sh' is on the remote server.

Hi,

you MUST have passwordless connections from hostA to hostB for a successful call of

rsh hostB 'command' (on HP-UX read: remsh ...)

There is no difference there between SUN, HP, ...

When you have setup this - do like the other collegues in the forum told - this will succeed.

If you want to have interactive entering a psssword with remoute command execution, use 'ssh'.
