CRAB server firewall.iptables now fixed, so it will restart without a reboot.

Leave a comment

For those of you familiar with my Linux server, y’all know that I run many custom BASH, Perl, and Python scripts.  We are going to discuss today my iptables firewall script, or actually the fact that I took the time to repair it.   Since upgrading the server to Fedora 20 in September 2014, my firewall script would start fine, but would choke on restarting, reloading, or running it over itself.  The end result would be that the server would sever all ports with the outside, effectively taking it down, needing a reboot to get it back online.  This was a real PITA, since I couldn’t really make any changes to the firewall without reboot.  I thought it was an end result of the OS changing from SysV init scripts to a systemd system.  How wrong I was….  The cause was simply a typo that I made while adding a feature, and a ‘done’ without a ‘while’ and a ‘fi’ without an ‘if’ stopped the script from accepting the restart and reload argument.  Most of the iptables rulesets were created before this typo, so it gave the ‘appearance’ that it was working properly.  Debugging a script of this size is a fairly daunting task, as the main firewall script is a healthy 50 pages, and its configuration file (one of a half dozen helper files) is about 7 pages long.  Since I’ve had a few questions about this firewall, I’ll share it with everybody…..

Download links are only viewable to logged in users.  All the other helper files, as well as these are all available upon request.  If you are a logged in user, and downloading these files, remove the .txt extension from the config and main files….

All in all, it was a fairly productive week off.  I have a few other minor syntax errors to chase down, but the firewall is operating within normal parameters…..

New server IP address

Leave a comment

Due to the migration to Frontier from ATT, the server’s static IP address has changed from 108.89.65.174.  It’s new IP address is:  32.220.54.46.

Also, the web pages at cap.vapor.com have been migrated to cap.crabradio.net, so that they fall fully under the crabradio.net domain, owned by me.

The subdomain webpage still has a cap.vapor.com graphic on it, but I’m hoping my friend The Moonshiner can come up with a similar graphic to just drop in.  😉

The only problems that you will encounter is if you attempt to load cap.vapor.com, as that dns is dead and unlikely to be updated.

I’m still waiting for the rest of the arcnet irc admins to update the US1 server IP address, and I shall reconnect us1.arcnet-irc.org to the rest of the servers.

Thanks for your patience.

Server sendmail and icecast info

Leave a comment

Well, I just noticed that the podcast and regular blog weren’t sending out email notifications any longer.  Pretty easy to track down.  For some reason, sendmail was not running.  Even easier to fix.  I simply did (as root):

# systemctl start sendmail

Tested the podcast’s php mail function, and all is well.

Something else that I’ve been chewing on for awhile and finally whipped a couple weeks ago.  I wanted my icecast server and IceS streaming source to behave like centovacast, with a ‘live’ mountpoint that ‘takes control’ of the stream…..  All I had to do is add these lines to /etc/icecast.xml:

<mount>
<mount-name>/stream</mount-name>
<fallback-mount>/live</fallback-mount>
<fallback-override>1</fallback-override>
<hidden>1</hidden>
<public>0</public>
</mount>

<mount>
<mount-name>/live</mount-name>
<fallback-mount>/autostream</fallback-mount>
<fallback-override>1</fallback-override>
<hidden>1</hidden>
<public>0</public>
</mount>

<mount>
<mount-name>/autostream</mount-name>
<fallback-override>1</fallback-override>
<hidden>1</hidden>
<public>0</public>
</mount>

Then, I just had to set IceS to send to the autostream mountpoint, instead of stream.  So, now, in absence of live, when you connect to the normal stream mountpoint, you fallback to live, then fallback to autostream.  The fallback-override directive allows a live source to ‘pull back’ listeners connected to the autostream.  😉
