e.g. string-matching CodeRed or Nimda viruses before they hit your Web server. The following rules achieve this: # DROP HTTP packets related to CodeRed and Nimda # viruses silently iptables -t filter -A INPUT -i $EXT_IFACE -p tcp \ -d $IP --dport http -m string \ --string "/default.ida?" -j DROP iptables -t filter -A INPUT -i $EXT_IFACE -p tcp \ -d $IP --dport http -m string \

Hello, I''m stuck IPSECing my wireless network at home and would appreciate any comments. I appologize in advance if I''m wasting your time with trivia - I''m not a professional and staring at the problem for days from various angles hasn''t done me any good ... My home server/firewall (morannon) is hooked up through an USB to ethernet adapter (eth1) to my DSL

Good Morning Mike, I''m finding that when I load a document, XXE is blindly removing all "superfluous" white space from "programlisting" elements. This of course is leading to a real mess (check out the FAQ on the web site :-( ). What can I do to avoid this? -Tom -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \

Hello, I am using Shorewall version 2.0.1 with kernel 2.4.20. Nightly, LogWatch emails a portion of the logs for my review. I notice that there are tons of dropped packets from port 445, somedays as many as 7,000. See sample below: >From 24.226.192.22 - 2 packets To 24.227.147.124 - 2 packets Service: microsoft-ds (tcp/445) (Shorewall:net2all:DROP:,eth0,none) - 2 packets My question is,

Hi there, I''ve read Routing on One Interface, and Shorewall and Aliased Interfaces docs but I''m a little confused, and all my test attempts have mostly failed. Here is my setup: CentOS 4.2 ShoreWall 3.0.2 My server has a subnet 192.168.50.0/29 routed to it via 192.168.1.2. Currently 192.168.1.2 is setup on eth0. With no ShoreWall involved routing seems to work if I just setup

Hello all, I’m running Shorewall 2.2.1 on linux kernel 2.6.10 with iptables 1.2.11. I recently ran a nessus scan of my firewall from a machine outside of the firewall and the nessus report told me that there are some ports open that I did not specify to be open. The ports are 32772/udp, 123/udp, 111/tcp, 32772/udp, and 53/udp. Why are these ports open when I did NOT specify them to be open

Having moved from a "cascading LANs" configuration to two independent LANs on eth0 and eth1, I still get some "state INVALID" for which I am not sure what the cause is. Can somebody help me understand its probable origin? Thanks, Costantino [see attachment]

Tom, I am NOT subscribed (yet). I dropped SuSeFirewall2 in favor of shorewall to get past the configuration hurdles I as experiencing. At the moment, when my SuSe 9.1 starts up, I can see shorewall processing the rules, policies, etc. and I see no errors and then moves on with the rest of the SuSe boot process . However, no traffic passes through using the rules. I run an iptables -L and I

This is kind of an odd request so I''ve got the asbestos undies on. I have a client who currently has a layer 3 switch plugged into a cisco pix. Routing is handled via RIP and now the client wants to insert a linux box running shorewall behind the PIX and in front of the switch to act as a content filter+backup firewall. The immediate problem I forsee happening is that RIP broadcasts to

Having study a number of documents on linux traffic shaper, I started to setup my shaping rules in my network. My linux box is running RH AS3 U3, shorewall 2.0.9.

Hello, I reinstalled my Slackware 10.1 a few days ago, before i did that i stored all files in /etc/shorewall to an external HDD. After reinstallation was complete i installed shorewall and restored the config files i backed up before, but now if the FW is running i can´t ping the adsl modem and so i can´t connect to the internet using pptp. Note, it worked before with exactly the same
