Ths SSH protocol supports tunneling arbitrary ports from your local host to a remote network that is only reachable through a remote gateway machine. The typical situation is that you have a, say, web server in a network which is only accessible from inside the network. If you have an ssh gateway machine within the network, you can get to the web server using tunneling. Continue reading SSH tunneling your way through multiple gateways
Here’s how to make dynamic IPv6 routing work between a Cisco IOS router and an OpenWRT Linux Quagga router. I couldn’t find a similar howto anywhere, so I decided to write my own.
I am using OpenWRT Kamikaze 7.09 (kernel 2.4) on an ASUS WL-500gP wireless router. Any IPv6 enabled Cisco router should do.
I assume you have already installed the IPV6 kernel modules and userland tools, and set up static addresses for your interfaces (if you haven’t check out the OpenWRT IPv6 Howto).
I am using SixXS for tunneling an IPv6 /48 prefix over IPv4. Continue reading Dynamic IPv6 routing with Cisco IOS and Quagga on OpenWRT
