Ah OK.
I did only byte overflow.
Packet overflow will take much longer. It's one of these very rare
cases where setting very small MTU is useful...
OK, another bug found.
Set your MTU to 100.
On two hosts, do:
HOST1_MTU1500# dd if=/dev/zero | ssh mana...@host2 dd of=/dev/null
HOST2_MTU100# dd if=/dev/zero | ssh mana...@host1 dd of=/dev/null
HOST2 with MTU 100 will crash after 10-15 minutes (with packet count
still not overflown).
Intersting. What are the packet counter at crash time (roughly)?
My - currently running - test is:
Guest 1 (Linux):
MTU 150
# cat /dev/zero | nc <guest2ip> 7777
Guest 2 (Windows 2003 Server):
MTU: 1500
# nc -l -p 7777 > NUL
My packet are currently at 63 million without a problem - yet.
