The problem I am facing now is that the QNX host could not ping the SCO host and vice versa. They are in the same domain, ie, 172.20.3.xx. As I am very new to Unix, I guess I must have missed out some important steps. Pls help... Thanx alot (2 Replies)

oarcp
oarsh(1) OAR commands oarsh(1)NAME
oarsh - remote shell connector for OAR batch scheduler.
oarcp - oarsh compagnon to copy files from a node or to a node.
SYNOPSIS
oarsh [OPTIONS] <NODENAME> [COMMAND]
oarcp [OPTIONS] [NODENAME:]<PATHNAME> [NODENAME:]<PATHNAME>
DESCRIPTION
Connect a node from the submission frontal of the cluster or any node.
OPTIONS
oarsh uses OpenSSH client (the ssh command) underneath to perform the connection. Thus any OpenSSH option can be used.
ENVIRONMENT
OAR_JOB_ID
From the frontal of the cluster or any node, specify the Id of the job oarsh must connect to.
OAR_JOB_KEY_FILE
Specify a job key oarsh must use, e.g. the one that was used for the submission of the job you want to connect to. This is mandatory
when connecting to a node of a job from a host that does not belong to the nodes managed by the OAR server the job was submitted to.
The -i option may be used as well.
CONFIGURATION
In order to provide the user with the ability to use oarsh to connect both the nodes of his job or other hosts that live out of the scope
of his job, oarsh tries to read two configuration files: first ~/.oarsh-host-include then ~/.oarsh-hosts-exclude.
If exist, those files must contain one regular expression matching a hostname per line.
At execution time, if oarsh finds in ~/.oarsh-host-include a match for the hostname used in the command line, it continues with the
execution of oarsh, skipping ~/.oarsh-hosts-exclude file. If not, it tries to find a match in ~/.oarsh-hosts-exclude and if one is found,
then executes ssh with the same command line. Finally, it no match is found (or for instance, if none of those files exists), it continues
with the execution of oarsh.
For instance, if all nodes look like name-XXX.domain, one may place ^[^.]+-[[:digit:]]+ in ~/.oarsh-host-include and .* in
~/.oarsh-hosts-exclude and then can use oarsh to connect any host.
The feature finally becomes really sexy when one considers placing a symlink to oarsh named ssh, and then can always use the ssh command to
connect any host.
EXAMPLES
Connecting from within our job, from one node to another one (node23):
> oarsh node-23
Connecting to a node (node23) of our job (Id: 4242) from the frontal of the cluster:
> OAR_JOB_ID=4242 oarsh node-23
Connecting to a node (node23) of our job that was submitted using a job key:
> OAR_JOB_KEY_FILE=~/my_key oarsh node-23
Same thing but using OpenSSH-like -i option:
> oarsh -i ~/my_key node-23
NOTES
All OpenSSH features should be inherited by oarsh, for instance X11 forwarding. However, one feature that oarsh does break is the SSH
Agent.
None of OpenSSH user configuration files (within ~/.ssh directory) are used by oarsh.
