Hi,

thanks for your reply.

you mean the udp address that is in form of ip:port

Yes it is easy I just put echo $4 > /var/log/ip in
ip-up script then I use cat /var/log/ip to read ; the
easiest way I think in scripting.

I use Mandrake 8.1 but mostly custimized (only base
system). I dont install cipe from them..

I did, everything is fine, compile the module,
ciped-cb etc..; insert module is fine, cipcb0 up but
not figure out what I put me and peer and ipaddr and
ptpaddr in my case that both is dynamic ip (dialup
user) and dont have a home LAN.

As I said before I dont intend to use it in home LAN
so what should I put in ipaddr and ptpaddr?

Ok I am going to test like this but not now as my
friends computer is not up all the time but correct me
if I am wrong some where and help me to finish :-)

Suppose his dynamic ip is 203.134.23.45 ; my is
203.123.43.65 ; we just have two boxes so after
modprobe cipcb  I could 

My box:
ciped-cb me=203.123.43.65:6789 peer=203.134.23.45:6543
ipaddr=? ptpaddr=?

His box:
ciped-cb me=203.134.23.45:6543 peer=203.123.43.65:6789
ipaddr=? ptpaddr=?

of course the key in /etc/cipe/options is the same for
both machine.
