Comment on Auto-closing SSH tunnels by Sarah

Sarah — Fri, 08 Mar 2013 01:16:09 +0000

In your example:
[me@local]$ ssh -f -N -L 25901:127.0.0.1:5901 me@remote.example.org; \
vncviewer 127.0.0.1:25901:1
The local port is the same as the port that is used in for vncviewer.

You explain that this is because:
“In order to connect to the remote VNC service through that tunnel, it is required to keep the connection to the ssh server open and, from another local terminal, connect to the local port 25901 with the vnc client.”

I don’t understand why this is; could you please explain further?

Say I want to send from machine A to machine C.
C is running a service on port “server-port” (which is any available TCP port).
The tunnel goes through machine B, which happens to be machine C, with port “middle-port” (again any available TCP port).

Why does A have to send from the “server-port”? Why can’t A send from any available TCP port? Wouldn’t it get forwarded along anyways? I’ve tried running this command where A’s local port is different than C’s “server-port”, and the data is forwarded, but I don’t know how to test if it is being tunneled with ssh correctly.

This explanation was REALLY helpful. Thanks for taking the time to do it!

Comment on How to change the expiration date of a GPG key by Ryan

Ryan — Wed, 27 Feb 2013 16:00:34 +0000

Thanks for this post George. I’m just getting back into encryption and realized, after generating a new key, that I hadn’t slapped on an expiration date nor, perhaps even worse, had any idea what was best practice (even though it’s kind of common sense to put an expiration date on something).

The tutorial is great and clearly outlines the steps needed to update a key. So, thanks again for putting this on the web.

Hi All,

I am having the same issue as Sandeep and Murali above. I have setup http compression on my apache configuration file as outlined in this journal but this does not produce the expected output.

Any insights would be appreciated.

Didn’t have the time to work on this plugin. I’ll check how can getting framed by Google Images be avoided.

Thanks for your feedback.
