Network security
Hi,
I have been playing around with kernel 2.4.2 lately, and suddenly my TCP
packets get rejected by some firewalls with the error:
TCP packet dropped (195.249.21.201->firewall.ao-vvs.dk[129.142.86.2]:
Protocol=TCP[SYN 0xc0] Port 58355->25): Bad TCP flags combination (received
on interface 129.142.86.2) (probable QueSO probe as flags=0xc2)
This error is taken from a firewall branded "Raptor" or something.
Is the 2.4.2 kernel's TCP/IP stack non-standard, the firewall just plain
stupid, or is there a security problem somewhere??
