I‘ve ssh gateway behind my NAT firewall. So all users must first login to my gateway host from the internet and then login to other machines on the LAN. This works great for cli based apps. However, few users would like to run x apps from internal LAN hosts and tunnel X display through intermediate ssh gateway and display back output on their local system. For example, from localsystem user makes connection as follows:

ssh -X user@gateway.example.com
ssh -X user@somelan.example.com

X forwarding fails with an error:

Error: Can’t open display:

How do I fix this problem and allow users to use X apps with my intermediate Linux / BSD gateway?

I’ve Squid Proxy server with over 100 Windows workstation. I see following error message in my cache.log file – “WARNING! Your cache is running out of filedescriptors”. Do I need to filter proxy server requests to avoid this problem? How do I fix this problem under CentOS / Fedora / RHEL / Debian Linux?

I’m behind a squid proxy server. How do I access internet via proxy server when I use wget, lynx and other utilities from a shell prompt?
