To port Forward general ports from a Linux box to a Windows Client
Problem: MySQL will only allow connections coming from localhost.<br> Solution: Port Forward port 3306 through a SSH tunnel. Connect to MYSQL on mysql.server.ie Putty: mysql.server.ie:22 user = steve pass = usual one <br> SSH Tunnel: Source port: 3306 Destination: localhost:3306 (Local Port)
On the Windows Client: mysql -h localhost -u steveb -p pass = password Use database
To Port Forward a Windows/ Samba Network share via an Outside Linux Box onto a Windows PC
Tunneling using Putty: In Tunnels Option → Source Port: 127.0.0.2:139 Destination: 136.x.x.x:139
In an Address Bar or Run box (Windows): \\127.0.0.2\sharename
Port Forwarding in Linux
This can also be automated in the ~/..ssh Directory
Has to be tested and confirmed: ssh -N -L 3333:136.xxx.xxx.xxx:5900 -x skynet.ie
Semi-Long Term Port Forwarding from Windows to Linux
Situation: you can connect to a Linux server on your LAN - however you need to access an external server through this linux server. You want to put a semi-permanent port forwarding in place.
You could use PuTTY using the method above - but putty would have to be open all the time.
Use portforwarding on the local linux server.
Login to the ssh server: ssh -f -g -L 3221:test.burkesys.com:22 -l username local.linux.pc sleep 600d // -f = fork into the background // -g = allow external clients from the LAN connect to 3221 // -L = Local port forward // -l = username of local linuxpc
telnet local.linux.pc 3221 //try the above on your local windows pc etc. It should connect through on port 3221. Note if the linux pc has a firewall - it wont work. To see if its working on the local linux pc: ps -eaf netstat -na More Info: http://www.howtoforge.com/nfs_ssh_tunneling
Long Term Port Forwarding using iptables
Not tested yet. I presume NAT will have to be used.
