Tonight I added fail2ban to one of my webservers to test it out. Here is my step by step, as best as I could figure it out...documentation a bit sketchy. feel free to add anything to it or suggest changes. I tried to set it up to deal with ssh, http authentication, dovecot, ftp, and postfix I could find no working example for centos 6 and there is no fail2ban book available to peruse. So,

Hi folks, Recently a customer of us moved his "old" asterisk installation, an 1.4.44 to a VMWARE infraestructure and has started having some weird issues. Asterisk started going slow and even refused to start up. After few tests, it only loaded when deactivating queues and iax2 (with noload in modules file). The thing is that it had been working with these modules loaded and lately it

Hello, fail2ban does not ban offending IP. NOTICE[29784] chan_sip.c: Registration from '"user3"<sip:1005 at asterisk-ip:5060>' failed for 'offending-IP:53417' - Wrong password NOTICE[29784] chan_sip.c: Registration from '"user3"<sip:1005 at asterisk-ip:5060>' failed for ?offending-IP:53911' - Wrong password systemctl status

So a few people just reported that they couldn't make any calls. I logged into asterisk and at first everything on the console looked normal, then I got swamped with messages about too many open files. This is from my asterisk/messages log file: [Oct 2 16:46:00] WARNING[19429] rtp.c: Unable to allocate RTCP socket: Too many open files [Oct 2 16:46:00] WARNING[19429] udptl.c: Unable to

If this is a small site, I recommend you download the free version of SecAst (www.telium.ca <http://www.telium.ca> ) and replace fail2ban. SecAst does NOT use the log file, or regexes, to match etc.instead it talks to Asterisk through the AMI to extract security information. Messing with regexes is a losing battle, and the lag in reading logs can allow an attacker 100+ registration

I have a new x3655 IBM and whenever the /etc/xen/scripts/network-bridge script starts, the ethernet would no longer work. This post isn''t about the cause, but the fix. I did a lot of tcpdumps and Googling, but I''ll spare you that. All they do is prove that yes, there is an issue. :) I tried Debian 4.0 i386/amd64 and Ubuntu 7.04 Server i386/amd64 and they all exhibit the

Hi All, Could anyone tell me the real use of "internal_ timing=yes" option on asterisk.conf file? I am using asterisk 1.4.22. As per my understanding if we don't have any TDM card installed with appropriate driver, we use internal_timing = yes to get the timing from ztdummy /ztDahdi. Is there any advantage on enabling "internal_timing=yes" even if we are proving timing

I have just tried this, and re-started fail2ban. It does not seem to have worked. I have looked at /var/log/exim/main.log and found

Hello! We recently upgraded one of our customers from 1.4.44 to 1.8.15-cert1. We have several other customers running both versions. The customer in question does not use us as their provider as they?re located in a different country. When they make outgoing calls, there is a 3 second delay between answering the call and the call being established. When debugging this, I found that Asterisk

Good afternoon list. I am experiencing a problem with the CDR and callfiles. What is happening is this: When generating a call with a callfile, everything works perfectly, but the CDR is recorded in the table when they answer the call destination. The field disposition is being recorded correctly, but the duration field is marked with the ring time and billsec is marked with 0. This just happens

Hello, I have been running Asterisk for the past 5+ years on RedHat and I never upgraded it before. All my Asterisk software is of the following release: 1) Asterisk 1.4.21.2 2) Libpri-1.4.4 3) Zaptel-1.4.11 I would like to move the OS to CentOS and then I thought I can at the same time ponder about upgrading Asterisk releases. However, I am bewildered by the myriad of different releases like 1.6,
