Full Discussion: script for nested rlogin and telnet
Top Forums Shell Programming and Scripting script for nested rlogin and telnet Post 302173331 by mcburke38 on Thursday 6th of March 2008 11:03:32 AM

I've made some progress. So far I can remsh into host1, then from host1 I can remsh into host2, and then from host2 I can telnet into host3 with this script:

#! /bin/csh

remsh host1 "remsh host2 "telnet host3""

The final hurdle I need to get over is executing a command on host3. I've tried:

remsh host1 "remsh host2 "echo 'command' | telnet host3""

But that didn't even seem to telnet me into host3, I got an error saying "no route to host". If I manually rlogin into host1 and then from there manually log into host2 and execute the command "echo 'command' | telnet host3" it works just as I'd like. I don't get why it can't do it via a script.

NAME

       hwloc-assembler-remote - Assemble multiple remote host topologies

SYNOPSIS

       hwloc-assembler-remote [options] output.xml host1 host2 ...

OPTIONS

       --ssh <ssh>
	      Use the given ssh command (and options) to connect to remote hosts.

       --lstopo-path <path>
	      Use  the	given path as the remote lstopo command when gathering remote topologies.  By default, lstopo is taken from the PATH envi-

	      Pass the given lstopo options when gathering remote topologies.

       --show Display the resulting topology before exit.

       -v --verbose

DESCRIPTION

       hwloc-assembler-remote is a frontend to hwloc-assembler.  It takes care of retrieving the remote nodes' topologies before  assembling  them
       with hwloc-assembler.

EXAMPLES

       To assemble three nodes topologies:

	   $ hwloc-assembler-remote output.xml host1 host2 host3

       To assemble the topology of a multi-process MPI job defined as a machinefile:

	   $ hwloc-assembler-remote output.xml `cat machinefile | sort | uniq`

RETURN VALUE

       Upon successful execution, hwloc-assembler-remote returns 0.

       hwloc-assembler-remote will return nonzero if any kind of error occurs, such as (but not limited to) failure to parse the command line.
