When I am on my way, I will post updates here and eventually sort them into better categories later…

Proxmox – installs with enterprise repo for no-subscription installations causing openvswitch-switch issues

If you’re also running into trouble with openvswitch-switch and really have no clue why it is not running as it should, you might also have a mismatch of a default no-subscription installation (it comes out of the box this way) and the default repo configured to work with the subscription/enterprise version only.

Unless you have a subscription key you will never get any updates for the PVE system itself – so before changing the network configuration to work with openvswitch-switch, change your repo in /etc/apt/sources.list.d/pve-enterprise.list as follows:

#deb stretch pve-enterprise
deb stretch pve-no-subscription

Update the package lists (apt update) and upgrade (apt upgrade) – you will get updates for openvswitch-switch!

Multi-Gateway change script for pfSense

Since pfSense is not actually rerouting router traffic itself (such as DNS, VPN, …) but only incoming traffic when a gateway goes down and another one is configured in the same gateway group, I have written the following script that you can use in a cron job. It will change the IPv4 default route for basically all traffic not specifically treated via FW rules – including the internal services.

  • MOBILE1 needs to be set to your second gateway, in my case a mobile LTE device
  • MOBILE2 and MOBILE3 need to be set to rarely used IPs – so the LTE traffic going there is not too much as
  • MOBILE2 and MOBILE3 need to be statically routed via LTE, always, to check their reachability
  • WAN1 needs to be set to your main gateway, in my case a FritzBox
  • WAN2 and WAN3 need to be set to pages you usually want to reach, but it is not so bad to be unreachable in case of a downtime of the WAN gateway as
  • WAN2 and WAN3 need to be statically routed via WAN, always, to check their reachability

The script will log changes and send mails to the email address configured in pfSense.

Sixxs Heartbeat Tunnel without Aiccu but Python (pfSense compatible)

For systems that do not provide Sixxs’ aiccu package to setup a GIF tunnel automatically, you can easily start the tunnel (not setup the routing 🙂 ) by executing the following script once per minute via cron:

This solution was first posted here:

Output JSON-Code in readable and sorted form so it’s diffable

This code will read in a JSON file and print it out again in readable form and keys in sorted order – making two files diffable!
