Setup Dahdi for asterisk on LXC container

[Dito]

Hello all,
i am moving to LXC with care using the proxmox openvz for years ...
wanted to know if there is a similar command from PCT to those one :

vzctl set $VENUMBER --devnodes dahdi/pseudo:rw --save
vzctl exec $VENUMBER chown -R asterisk /dev/dahdi /lib/udev/devices/dahdi
vzctl exec $VENUMBER chgrp -R asterisk /dev/dahdi /lib/udev/devices/dahdi​

those commands with vzctl will let the container to access the dahdi source on the node to make conferences work with asterisk pbx. i hope there is similar commands with PCT ..

what a silence

Hi,

I bridged the USB dongles to my LXC container that runs asterisk. For this I added to the file /etc/pve/nodes/pve/lxc/_ctno_.conf

lxc.cgroup.devices.allow: c 188:* rwm
lxc.cgroup.devices.allow: c 189:* rwm
lxc.mount.entry: /dev/bus/usb dev/bus/usb none bind,optional,create=dir
lxc.mount.entry: /dev/ttyUSB0 dev/ttyUSB0 none bind,optional,create=file
lxc.mount.entry: /dev/ttyUSB1 dev/ttyUSB1 none bind,optional,create=file
lxc.mount.entry: /dev/ttyUSB2 dev/ttyUSB2 none bind,optional,create=file
lxc.mount.entry: /dev/ttyUSB3 dev/ttyUSB3 none bind,optional,create=file
lxc.mount.entry: /dev/ttyUSB4 dev/ttyUSB4 none bind,optional,create=file
lxc.mount.entry: /dev/ttyUSB5 dev/ttyUSB5 none bind,optional,create=file
lxc.cgroup.devices.allow: c 10:200 rwm

and for the PCI soundcard:

lxc.mount.entry: /dev/snd dev/snd none bind,create=dir,optional 0 0
lxc.cgroup.devices.allow: c 116:* rwm

In the container I had to create the /dev/snd entry point and for /dev/ttyUSB* I had to fix the user:group owner so that asterisk can access it.

I hope this helps,
Rares

Hi Dito,

Did you manage to get it work? /dev/dahdi is a file or a folder? Can you adapt the example from /dev/ttyUSB that is a file or the one from /dev/snd that is a folder? To find the cgroup numbers you can just do a: ls -l /dev/dahdi

I have LXC working all over the place and no problems so far. I think it's just a matter of accommodation to the new system.
