Can't be any better explanation than this. I've changed the standard SSH port (22) on my server to something else, and I will need to forward that port from my Wireless router and then I should be set. Johnny,

Thanks a lot! Can’t be any better explanation than this.

I’ve changed the standard SSH port (22) on my server to something else, and I will need to forward that port from my Wireless router and then I should be set.

This is where the SSH client will connect. Port 50000 is where the tunnel will listen for incoming connections, and these connections will then be forwarded to the host localhost on port 5900 on the other side. So there are two steps involved here: 1. The SSH connection is established, which is done from from the client to the server on port 22. client:anyport --> your.home.pc:22 2. The tunnel is established over the above connection. It has its endpoints in the client port 50000 and the remote host at localhost:5900 like this. client:50000 => client:anyport --> your.home.pc:22 => localhost:5900 The endpoint localhost:5900 could be changed to any host and port, like <a href="http://www.google.com:80" rel="nofollow">www.google.com:80</a> that the SSH server can access, so then the tunnel will terminate there instead. So if you go to localhost:50000 on your client, you will end up at <a href="http://www.google.com:80" rel="nofollow">www.google.com</a> on port 80, tunneled through your SSH connection. Hope I didn't confuse you even more. @shak Hello,

In you example, port 22 is the port where the SSH server listens for incoming connections. This is where the SSH client will connect. Port 50000 is where the tunnel will listen for incoming connections, and these connections will then be forwarded to the host localhost on port 5900 on the other side.

So there are two steps involved here:

1. The SSH connection is established, which is done from from the client to the server on port 22.

client:anyport –> your.home.pc:22

2. The tunnel is established over the above connection. It has its endpoints in the client port 50000 and the remote host at localhost:5900 like this.

client:50000 => client:anyport –> your.home.pc:22 => localhost:5900

The endpoint localhost:5900 could be changed to any host and port, like http://www.google.com:80 that the SSH server can access, so then the tunnel will terminate there instead. So if you go to localhost:50000 on your client, you will end up at http://www.google.com on port 80, tunneled through your SSH connection.

Hope I didn’t confuse you even more.

I found this one much more straightforward than any other on the web. But I am still a little confused about the ports. As you explained above when you tunnel thru ssh via: $ ssh -l username -L 50000:localhost:5900 your.home.pc you said 50000 is the port on my machine, 5900 is the port on remote machine. But I've seen some other people use "-p 22" or any nonstandard port number such as "-p 1023". What is this port defined by -p as in, for example: $ ssh -l username -L 50000:localhost:5900 -p 22 your.home.pc Hello Johnny,

$ ssh -l username -L 50000:localhost:5900 -p 22 your.home.pc

I was able to make a connection to my home machine using the Terminal Server Client. The only problem is that the only part of my home screen is the small area where authentication window was which is probably only about 1/20th of the whole screen. The rest is blank. Any ideas ? Again thanks for the help Johnny. Thanks for the tutorial. I was able to make a connection to my home machine using the Terminal Server Client.

$ ssh -X user-name@ip-address
$ vncviewer localhost

we can use -via option of vncviewer

like,,
$ vncviewer -via user-name@ip-address1 ip-address2

ip1 and ip2 can be same,,,,

However it did not allow vnc to connect to it. (Probably some setting on that system is required). I don't mind it though coz i can still see all my data. However, i want to copy data from that computer to my current computer in konqueror etc. When i try now it says it can't be copied. How to go about this? Awaiting an early reply. Regards hildebrand victor Hi Johnny
