Hi,
I've been trying to file a bug report trough the bug report tool of
Debian. But without a succes.
So I'll just inform you all about this bug since I do want to inform you
about it.
I'm sorry this isn't the proper method, but bugreport isn't cooperative
with my SMTP for some reason.
I've discovered that fwsnort generates a small but significant syntax
error when this iptable rule is present: # ICMP echo request
$IPTABLES -A OUTPUT -p icmp --icmp-type 8 -j ACCEPT
The below fwsnort rule is generated which makes 'iptables-persistent'
crash on boot, which in turn boots Debian without a firewall.
-A FWSNORT_INPUT -p icmp -m icmp --icmp-type 8 -m string --hex-string|
0102030405060708090a0b0c0d0e0f| --algo bm --to 74 -m comment --comment
sid:2100369; msg:GPL ICMP_INFO PING BayRS Router;
classtype:misc-activity; reference:arachnids,438; rev:7; FWS:1.5; -j
LOG --log-prefix [11] SID2100369 --log-ip-options
The right syntax should be: --hex-string |
0102030405060708090a0b0c0d0e0f|
It's a small syntax error, I'm sorry I don't have the time to fix this
bug. I hope I've given enough information to you to fix this problem.
In the mean time this can be fixed by editing the saved iptable
configuration in /etc/iptables/rules.v4
To display some helpful debugging information you can run: #
iptables-restore /etc/iptables/rules.v4
This will inform you of the line where this syntax error is. Then edit
it accordingly with your favorite text editor.
