Re: cygwin + ssh + VPN very slow

At home I use cygwin on my XP box and through the VPN tunnel I am
successful in opening up an XTERM connection to a new 64 bit, redhat
LINUX computer in the office. To start the xterm I use

$ startxwin.bat

In the xterm that pops up I type

$ ssh -Y user@computer_name

Firstly I am not sure why you need VPN. If your office machine is not firewalled or at least ssh access is not blocked, you just just ssh into it from your home machine (I recommend putty as the win32 ssh client), and enable X forwarding. And you run any X server on your home machine. Then problem solved.

Even if you cannot directly ssh into your office machine, but you can ssh into your company firewall them jump to your office machine. You can still achieve this without VPN. What you need to do, is to use ssh proxy command to redirect everything to your linux machine at office. Here is a good read,

The last chance you need vpn, I would recommend OpenVPN. It is easy to set up, and very secure, crossplatform.

As for X server, I personally prefer Xming,
http://wiki.freedesktop.org/wiki/Xming
It is lightweight. It doesn't depend on cygwin enviroment (this is sometime useful as only one version of cygwin1.dll can be run on the system; so if you have several programs relying on cygwin and each only works with different version of cygwin, you are then out of luck). I found the commbination of putty+Xming is more flexible than openssh+cygwin/X.
