Public bug reported: Binary package hint: ubuntu-docs
I have implemented the SSH VPN as explained in the document: https://help.ubuntu.com/community/SSH_VPN/ But at least I can confirm that it is not working with Ubuntu 10.10 as Machine B and Ubuntu 8.04 as Machine A. I managed to make it work by using smaller netmask on the tun0 interfaces in both endpoints smaller. I used netmask 255.255.255.255 in Machine A, like shown below, for an eth0 IP address of 192.168.0.15 in Machine A ethernet: Machine A: iface tun0 inet static pre-up sleep 5 address 192.168.0.15 pointopoint 192.168.0.14 netmask 255.255.255.255 up arp -sD 192.168.0.14 eth0 pub I suspect that if you use the same netmask in Machine A as in the ethernet interface there is a route conflict, but if you use a more restrictive netmask that one will be the preferred route. Also when I bring down the tunnel in Machine B with the command "sudo ifdown tun0" this will bring down the tunnel, but it will not bring down the ssh session. That one you have to kill it manually. Otherwise if you bring again the tunnel up with "sudo ifup tun0" the tunnel creation will fail! To fix this, in the "Automating it all with ifup/down" section in Machine B you have to add a new entry in the very bottom: down pkill -9 -f 'ifup tun0' This will kill the ssh session when you execute "sudo ifdown tun0" in Machine B. It would be good also to include that you should run "sudo ifup tun0" to bring up the tunnel and "sudo ifdown tun0" to bring it down and recover the proper interface configuration and routes in order to continue using Internet just as you were doing in the very moment before the tun0 was brought up.
