Linux 2.2.10 ipchains Advisory (fwd)
...agments that
do not contain enough information for transport protocol header analysis.
Fragments that start at offset 0, and are not long enough to provide complete
transport header information are treated like fragments with an offset > 0
(> 1 in the TCP case). This is the relevant code from ip_fw.c:
if (offset == 0) {
unsigned int size_req;
switch (ip->protocol) {
case IPPROTO_TCP:
/* Don't care about things past flags word */
size_req = 16;

What is someone looking for??
I am currently blocking out netbios UDP port 137 on my firewall and was
wondering what the following means in terms of security:
Jul 9 16:19:05 oscar kernel: IP fw-in rej eth0 UDP SOMEONES_IP:137
MY_IP:137 L=78 S=0x00 I=46484 F=0x0000 T=111
I have gottena few 100 of these and was wondering if there are some
vulnerabilties related to netbios out there?? What do the S/I/F/L fields
stand for?? I

IPFW Problems?
Hi,
I have a system with a 4.11 Kernel. Unless I'm doing something very
wrong, there seems to be something odd with ipfw.
Take the following rules:
ipfw add 00280 allow tcp from any to any 22 out via bge0 setup keep-
state
ipfw add 00299 deny log all from any to any out via bge0
ipfw add 0430 allow log tcp from any to me 22 in via bge0 setup limit
src-addr 2
ipfw add 00499 deny log

Hey Guys,

Config & make weren't complaining so, installed the kernel, reboot and there
it was:
>IP packet filtering initialized, divert disabled, rule-based forwarding
enabled, default to deny, logging disabled
Another rebuild didn't work out so... I reviewed
