Somebody have a success story creating a vpn based on pptp , (and, yes, i know, insecure in current days), using a debian 10 container with pve version 6.x.x ?
LXC is a host kernel partition more or less equivalent to a BSD jail or chroot with some pre-applied apparmor profile and pre-allocated cpu/mem/dev resource pool.
You are trying to access a library via an LXC that isn’t accessible to the default image template in its current config. The following
pct set xxx --mp0 /lib/modules/$(uname -r),mp=/lib/modules/$(uname -r),ro=1
in the host will grant the xxx container access to all host kernel libs.
Be very careful with this, it is a dangerous security issue in itself, not to mention PPTP is known compromised protocol that can be sniffed, intercepted and decrypted/encrypted on the fly by numerous documented bad actor toolkits.
I highly recommend you not implement PPTP to any endpoint outside your network.
(and, yes, i know, insecure in current days) Obviously this person is testing something, hopefully security-related. And yes, this issue is Promox-related, because the problem lies in the LXC modprobe map dictated in Proxmox by default.
you are 100% right, is only for create a scenario for show the students how insecure can be to use pptp, there are a few well known tools for intercept or grab data from a pptp channel
in terms of preferences, if some body ask me, wireguard is the best solution for vpn at this time
