Note: For a production installation you may want to copy the SSHOSS program to an OSS standard bin directory,
renaming it to "ssh". Alternatively, you may also create a symbolic link.
At the TACL prompt, run the SSH client to execute a command on a remote system as follows:
$DATA1 MHSSH 286> run ssh m.horst@10.0.0.201 whoami
SSH client version T9999H06_22Jan2014_comForte_SSH_0097
You have no private keys in the key store.

To Establish a Port Forwarding Tunnel with the NonStop SSH Client
Forwarding Local Port to Remote Port
You can create port forwarding channels for both the OSS SSH client (SSHOSS) and the Guardian SSH client (SSH).
The following example illustrates how to establish a port forwarding tunnel for telnet sessions over SSH, using the
Guardian SSH client:
$US SSH90 46> run ssh -N -L 5021:localhost:23 joe@10.0.0.111
SSH client version T9999H06_22Jan2014_comForte_SSH_0097
The –N option suppresses the start of a remote shell. The –L option tells SSH2 to listen on port 5021 and forward any
incoming connection to the remote SSH daemon and further to a telnet server on the same host, listening on port 23. The
"localhost" in the command line refers to the target host of the forwarding tunnel, i.e. when using -L option this is the
remote host.
After the SSH session is successfully established, the SSH process will wait until the SSH session is terminated or it is
stopped. Thus, if you hit <break>, you can get the TACL prompt back and try to connect a telnet session over the SSH
tunnel:
<break>
$US SSH90 47> telnet 127.0.0.1 5021

In this example the local telnet client connects through the tunnel to the telnet server on remote host 10.0.0.111 that
listens on loopback address 127.0.0.1, port 23.
Forwarding Remote Port to Local Port
Port forwarding channels can also be enabled in the opposite direction, i.e. from a remote port to a local port. The
following example illustrates how to establish an SSH port forwarding tunnel from a remote host to the local host, using
the Guardian SSH client:
