Not supported on Hannah Montana Linux?? FORGET YOU GUYS!

No, seriously ..

Is there a Hannah Montana Linux? Really? Really??

Another great article: thanks. You did not say much … in fact anything, unless I missed it.. about DAHDI support. As far as I can tell, the CuBox PCIe ports aren’t populated. I still run my own Asterisk variant on a fair-sized old machine mainly because I want to support a DAHDI gateway that needs PCI. I have looked at using an Intel Galileo that support micro-PCI (which can be used with PCIe) but have not yet taken that plunge. I would think supporting a DAHDI bridge would be a requirement for many home users, and would love to hear your thoughts on how to get there. For example, the HummingBoard-i2eX is made by the same company as the CuBox, I think and it supports PCIe. It seems like it should be CuBox compatible.

Sorry for posting here about Pogoplug 4 but apparently your forum has decided that my new account I have created just to reply does not give me any privileges to post. I’m quoting Nerd from the Pogoplug forum post:

"2. MySQL likes about 40MB of RAM as a minimum. When you only have 128MB, that can be problematic. Apache likes boatloads of RAM. Asterisk appears happy at 20MB when nothing much is happening. We avoided RAM exhaustion by setting up a 256MB swap file, but that can be a problem, too, since you’re operating with an SDcard. Possible solutions: (1) Don’t install FreePBX which eliminates the need for MySQL, Apache, and PHP… but what fun is that. (2) Build the image you want to use with step #1 above and never use a browser to open FreePBX. This keeps Apache usage to a minimum just handling FreePBX’s operational requirements for managing calls. In this setup, the Yahoo News app runs without a hiccup, and it’s a memory hog: sox and mpg123 easily consume 98% of the RAM resources just processing the text-to-speech for the call. But only 192 bytes of swap file were required to process everything without any noticeable degradation."

Here is my experience. I have been running Asterisk+Freepbx (3 servers) for about 9 years on this piece of cheap hardware: http://www.amazon.com/RCA-RM4100-Internet-Media-Player/dp/B0096SIHJS
It only has 128MB but with few tricks Freepbx interface is pretty snappy. 1st advice: forget about Apache, it is a bloatware compare to lighttpd. Believe me, whole Freepbx runs without a hiccup on lighttpd instead of Apache, it take about 10 min to swap the web server and configure it.
2nd advice: Minimize memory footprint of MySQL. How: swap default database engine to MyISAM. Of course it means that existing databases has to be rebuilt (if there are any). To do this just add lines to my.cnf

skip-innodb
default-storage-engine=MyISAM

Hope this helps! (I have around 10 registered trunks, 15 extensions, 3 google voice accounts and chan_dongle). I’m using around 60% of memory with asterisk+freebpx running plus openvpn plus racoon+xltpd. No issues!

[WM: Great suggestions. We always dump InnoDB, but tip #1 is worth a careful look. Thanks.]

Please check out SPA instead of regular port knocking. Port knocking can be replayed where SPA gives you all the advantages but additionally can do encryption preventing any replay attacks or lucky guesses from an attacker. It works on Ubuntu as well:)
