RSH problem

Mulder_1 — Fri, 27 Mar 2009 08:24:08 GMT

I receive this error when I issue RSH :

$:> rsh 192.168.25.5
%RSH-E-SERVNOTAVAIL, Remote service is not currently available
-SYSTEM-F-REJECT, connect to network object rejected

The service is enabled,nor sure if it is blocked somewhere in the network.Please suggest.

Is the TCPIP show service done at the target host 192.168.25.5 ?
Is the accept host visel.rtco.com the one You trying the rsh command ?

The accept command is blocking all but the specified host.

The target is having the same info :

Yes, and my question was also:
is visel.rtco.com the source (requester) of the rsh command ?
If NOT, then the accept host entry is the reason why it rejects the connection.

What about "rlogin"? An RSH command with no
remote_command on the line uses the RLOGIN
service, not RSH.

alp $ help rsh

RSH

[...]
When using the RSH command, consider the following:

o If you omit a command for remote execution, RSH initiates a
remote login session (see the RLOGIN command).
[...]

I believe that "-SYSTEM-F-REJECT" here is
equivalent to the UNIX "Connection refused",
that is, there's no server there.

Of course, the first test would be to add a
remote_command. For example:

rsh 192.168.25.5 show default
