I got it running now.
The console ist not very helpful so i will ask:
What is the basic OS, kernel, etc.?
Where is my bash? What are the other software components, openVPN, strongSWAN, PostgreSQL, opsnSSL ...?
How can i have a look into iptables/nftables-chains?
How can i debug with basic system commands like tail, grep, awk, etc.
I was not happy about the move from Squid to a self designed software, it would have been better to provide the extra functionality back to the OpenSource projects.
This was working fine for the Netfilter framework, i was working on with Harald Welte.
For debugging, inspecting live logs, the Web Interface is far too slow.
Cheers!
