The other day I helped another 44net user troubleshoot his IPIP configuration by running a traceroute from our network. He asked, "what is the last working hop?" I decided it might be useful to the community at large to release a tool that allowed doing this test from our network without waiting for me to run a command. Here it is: http://trace.hamwan.net/ It is simply a web interface to mtr. I hope this allows people to confirm their IPIP tunnels are working properly. The tool is published on non-44net IPv4 and IPv6 addresses, in case your tunnels aren't working properly yet. (This plan might not be as good as I'd hoped, because the DNS is still on 44.24.240/20.) The source IP for the actual traceroute will be 44.24.241.98. If you would like to deploy this on your piece of 44net, or improve the code, the source is available here: https://github.com/kd7lxl/mtr-web Tom KD7LXL
