PROBLEM

    Dimuthu Parussalla found  following.  There  is a buffer  overflow
    hang  in  linux  debian  distributin  kernel  2.2.10 with ipchains
    1.3.8, 27-Oct-1998.   He tested with  a linux running  with debian
    above version of  kernel and ipchains.   First we setup  the linux
    box to handle IP Masquerading as follows.

        ipchains -A forward -j MASQ -s 192.168.0.0/16

    Then from a local workstation within the 192.168.0.0 network.   We
    ssh to the linux box and did the following

        $ping -f <ip.address>

    And we opend a  another ssh session to  the linux box and  did the
    following

        $ping -l 6512121 <ip.address>

    After a few minutes.  Ipchains hangs and the linux server hangs..

SOLUTION

    Ipchains-patch.gz will fix the problem.
