I am using linux kernel 2.6.25. I have tried installing tun-1.1. After I use "modprobe tun" , and use "ps aux | grep tun" , I can not see any id (a blank line prints). I am not sure if it is correctly working or not.
Secondly, I have a problem using sgsnemu. I am running sgsnemu and ggsn on machines with IP 192.168.1.87 and 192.168.1.88 respectively. I use remote 192.168.1.88 and when it comes to the listening address, I'm lost. Please guide me on what address to use for listening in sgsnemu.conf file ? I am using a LAN net 192.168.1.0/24.
