About

• I faced bandwidth issues between a WG Peer and a WG server. Download bandwidth when downloading from WG Server to WG peer was reduced significantly and upload bandwidth was practically non existent.
• I found a few reddit posts that said that we need to choose the right MTU. So I wrote a script to find an optimal MTU.
• Ideally I would have liked to have run all possible MTU configurations for both WG Server and WG Peer but for simplicity I choose to fix the WG Server to the original 1420 MTU and tried all MTUs from 1280 to 1500 for the WG Peer.

Testing

• On WG server, I started an iperf3 server
• On WG peer, I wrote a script that does the following:
  • wg-quick down wg0
• Edit MTU in the /etc/wireguard/wg0.conf file

Exposing zfs snapshot to windows previous version using samba vfs_shadow_copy2

This was much trickier than I had originally anticipated and have spent a few hours testing.

The config from samba wiki absolutely works, but it wasn't ranked higher in search engine and it's not general enough. https://github.com/zfsonlinux/zfs-auto-snapshot/wiki/Samba

Tested on ubuntu 22.04LTS, samba 4.15.9 and windows 11.
