Hi, I have a problem with asterisks on Linux. Looks like it is a iptables problem. My external client (eyebeam, on a different computer) cannot register to the asterisk server, but the asterisk server itself *looks* working. If I dial one of the incoming phone numbers for the server, I can see the call arriving in Asterisk (using asterisk -r). I tried nmap on my server, and this is the result:

Hello. I'm moving from a very old Fedora Core 1 to CentOS 4.4, what a change!! Three year ago, I wrote some script (network related) and worked very well. Now, I can put into init.d by means of chkconfig and I restarted the system, but always hang when executing my srcipt (in my new centos 4.4). There a manual for making scripts for init.d? there is some new requirement by which it does not

Hi, I''m having issues with policing my incoming traffic by matching packet marks made by iptables. I''ve checked as many sites and guides as I can find, and I seem to be doing the exact same thing as they all are, but there''s still no success. As such, I was wondering if anyone can have a quick look to see if I''ve done anything obviously stupid? Essentially, I

Hello Leon. In addition to everything else mentioned in this thread, I'd recommend you a great book on the topic. "Attack Detection and Response with iptables, psad, and fwsnort by Michael Rash" It contains a really nice and detailed guide on iptables and most common attacks, nmap, psad and snort. Regarding your config, I'd like to point several things: 1. You're not

I have a dual homed server in an install for someone who is very cost sensitive. This server originally is being setup as an Asterisk server, but now the simplest thing for me to do is also set it up to provide internet access for the small shop as well. So it will have one external, WAN facing nic that needs all incoming ports except UDP 5060 and 10000 -> 60000 blocked for all but two ips.

Dear Members Thank you for your replies. @Anthony K. -- One of the articles that I have read mentioned that the file gets read from the top to bottom and apply the rules accordingly. In addition the article also explained that if there is no matching rule, the default policy will be applied. The writer suggested that rules with the highest chance to match should be in the beginning of the

Hello, I want to test Shorewall''s IPsec feature. It requires patched netfilter (and kernel but that''s another story). I didn''t want to replace my distribution''s iptables package with my own compilation so I installed it to another prefix. Now Shoreall uses the iptables command found first in $PATH. I don''t think this is the most elegant way. I
