How to Configure Port Forwarding in Secure Shell

Port forwarding enables a local port be forwarded to a remote host. Effectively, a socket is allocated to listen to the port on the local side. Similarly, a port can be specified on the remote side.

Before You Begin

You must assume the root role. For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2 .

1. Configure a Secure Shell setting on the remote server to allow port forwarding.

   Change the value of AllowTcpForwarding to yes in the /etc/ssh/sshd_config file.

   # Port forwarding
   AllowTcpForwarding yes

2. Restart the Secure Shell service.

   remoteHost# svcadm restart network/ssh:default

   For information about managing persistent services, see Chapter 1, Introduction to the Service Management Facility, in Managing System Services in Oracle Solaris 11.2 and the svcadm(1M) man page.

3. Verify that port forwarding can be used.

   remoteHost# /usr/bin/pgrep -lf sshd
   1296 ssh -L 2001:remoteHost:23 remoteHost
