there is a buffer overflow hang in linux debian distributin kernel 2.2.10 with ipchains 1.3.8, 27-Oct-1998.
here is the explanation.
We 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..
Ipchains-patch.gz will fix the problem.
THE UNDERTAKER -> EFNET -> REAL CRACKING
!!!REST IN PACE!!!!
