snipe-it lxc proxmox pptp problem

[PAOK1926]

hello,

i just installed snipe-it as lxc on my proxmox server. everything seems to work fine, except, i cannot add a pptp tunel to my vpn server. when i try to initiate the pptp connection, i get this message:

Couldn't open the /dev/ppp device: Permission denied
/usr/sbin/pppd: Sorry - this system lacks PPP kernel support

is this true ? this system lacks PPP kernel support ?

Hi there,

This is a limitation of running in an unprivileged LXC container.

To work around it, you have 3 options:

• run the container as privileged (and deal with all the bugs and issues that will bring)
• download the ISO instead (from the Snipe-IT page on our website and install to a "proper" VM; or
• (probably the most relevant option) explicitly set up the required resources/permissions.

Assuming that you are using Proxmox, here is a thread that seems related to the 3rd option I noted: https://forum.proxmox.com/threads/ppp-on-multiple-containers-not-working.54714/

If you're not using Proxmox and/or you want more general LXC info, please have a look at these: https://discuss.linuxcontainers.org/t/lxc-allow-openfortivpn-client-to-create-a-ppp0-interface/3048/2 https://discuss.linuxcontainers.org/t/dev-ppp-in-lxc-permission-denied/8326

If you work it out, please post back as I'm sure it will help others.

I'm closing this now as there's not really anything we can do about it.

If you worked it out @PAOK1926 - please still free to post back with instructions.
