I've installed vpnc, kvpnc gui and the kernel support for tun. So I have a device /dev/net/tun , vpnc starts with no problems and no errors, but when I try to connect it says:
binding to port 500: Address already in use
I have iptables turned off, so I've no firewall. I connect to my wireless router and it's connected to my DSL.
I have to connect to cisco vpn, but I want to use vpnc and not the cisco vpn client. I don't have some previous vpnc session running on port 500.
So, do have any ideas, what does this mean?
