He wrote more than 7k+ posts and helped numerous readers to master IT topics. Also M0n0Wall is a good one, also based on FreeBSD. Vivek Gite is the founder of nixCraft, the oldest running blog about Linux and open source. Table, the main author of Firewall Builder.

conf file, we see PF implementation of the same policy rules (this is just a fragment with first few rules): # Tables: (2) For PF fwbuilder generates two files for each member firewall. After the cluster is switched to “PF”, the list consists only of “CARP” and “None” as shown in Figure 28:įigure 28. Failover protocol choices for PF/OpenBSDįigure 30. “CARP” was not in the list because it is not available on Linux. While cluster was set up as “iptables”, possible choices of failover protocols were “heartbeat”, “VRRP”, “OpenAIS” and “None”. Its a wrapper around tkinter that presents the programmer with a very Python-like interface. Anywhere tkinter runs PySimpleGUI should run. Runs on Python3 on Windows, Mac, Linux, pypy, Raspberry Pi. List of available protocols depends on the firewall platform chosen in the parent cluster object. PySimpleGUI is a new one thats great for beginners and intermediate GUIs. The protocol is configured in the failover group object. To switch to OpenBSD from Linux we need to change failover protocol from heartbeat to CARP as well. This should fix the status of both members in the failover group dialog. They should match exactly, so we have to reconfigure the cluster object to platform “PF” and host OS “OpenBSD” as well. Failover group indicates that the cluster configuration does not match membersįailover group declares status of both members “Invalid”, this is because the platform and host OS of members do not match configuration of the cluster object anymore.
