Sshlink

General

Development

A well-known method to connect a host that remains behind a firewall is using a SSH backlink with a remote port forwarding. While that's a fairly easy task, sshlink makes it simpler.

Examples

Imagine you want to create a ssh link from your computer to host1 (web access) and host2 (SSH access), with sshlink user and /etc/sshlink.identity for RSA/DSA identity file (with 12345 for passphrase).

Sample sshlink.conf

# Configuration file for sshlink

[default]
ssh_command="ssh -i /etc/sshlink.identity -l sshlink -o StrictHostKeyChecking=no"
log_time=3600
checkalive_time=30

# Examples

[host1]
ssh_args="-R 8080:localhost:80 host1.net"
#connect=yes

[host2]
ssh_args="-R 2222:localhost:22 host2.net"
#connect=yes

Uncomment connect parameters and run sshlink from command line. You should be able to access from host1 (web service through port 8080) and host2 (SSH service through port 2222).
