Hi,

1) Is there any reason why max_pseudo_channels defaults to 512? I want to increase it by default but at the same time don’t want to outsmart the developers if they had a good reason for it.
2) I had a look at http://lists.digium.com/pipermail/asterisk-users/2014-March/282607.html but that did not seem to work. Does anyone have tips on how to make it persistent on reboots?

TIA.

Dovid

One thought on - Max_pseudo_channels

  • The limit is set to 512 in order to prevent a non-priveleged user from launching a denial of service attack on the local machine.

    See https://github.com/asterisk/dahdi-linux/commit/e5cbedbf37edf2a2350ec77d87f4866f05a2a4ff

    What specifically did not work?

    Depending on your distribution, you will want to add options for the dahdi module on load to the /etc/modprobe.d/ directory to make the settings persistent. When the mailing list post you linked was first written, there was only a single /etc/modules.conf file. That single file has been split up into multiple files in /etc/modprobe.d now.

    I hope this helps, Shaun
