File fwsnort.sh missing and no chains created

[Huntingtor]

Server OS: Ubuntu 18.04.5 LTS Kernel: Linux 4.15.0-132-generic Psad is installed.

I just installed fwsnort with no issues via apt-get install fwsnort. After install I ran into some problems.

• A single log entry: iptables ipv4options extension not available, disabling ipopts translation.
• No chains have been inserted into iptables rules.
• The command fwsnort --ipt-apply ended up with /var/lib/fwsnort/fwsnort.sh does not exist. at /usr/sbin/fwsnort line 3410.

Indeed, fwsnort.sh doesn't exist in my filesystem. Neither in your repository, not in the download from CipherDyne nor in the Ubuntu package itself.

What is the iptables ipv4options extension? Is there a kernel module missing? Where can I find the fwsnort.sh?
