Hi,

I am trying to set up a CIPE server on the redhat linux 9.

I have done the following:

>Edited a file : /etc/sysconfig/network-scripts/ifcfg-cipcb0

DEVICE=cipcb0
ONBOOT=yes
USERCTL=yes
MYPORT=6789
PEER=67.xx.xxx.161:6790
PTPADDR=192.168.0.2
IPADDR=192.168.0.1
NETMASK =255.255.255.0

>/etc/sysconfig/network-scripts/ifup-cipcb ifcfg-cipcb0

>ifconfig

The ifconfig shows the Mask as 255.255.255.255
How can i change this? Any ideas??
