In my case, I can't simply upgrade to the latest Debian (or any other distro), as one of the systems is our home firewall and gateway -- with iptables, multi-LAN routing (with local DNS), a bit of bridging, encrypted tunnels to elsewhere, etc. This means we would lose *all* Internet connectivity for who knows how long if I tried an in-place upgrade. So the only way to move forward seems to be to rebuild our system on separate hardware. I have started this on hardware I already mainly have (being retired, and thus without corporate budget or staff). Then I plan get the new build more or less working, and hope that I don't have to move cables between the old and new (and change IP addresses back and forth) more than a few times, thereby only having a few short periods of time without Internet connectivity. Finally, building this new system is made even more difficult by the fact that iptables has recently been replaced by nftables, whose native syntax has been "improved" to be quite different. There is, at least, a legacy iptables interface to it, and it may actually be behaviorally identical to the old iptables for my > 2000 custom rules (built up over a dozen years) which govern LAN[i] <=> LAN[j] and LAN[i] <=> Internet routing and firewalling. P.S. The last time I upgraded our firewall, from x86 to x86_64, at least iptables was quite compatible with ipchains, and Linux as a whole was still in the early stages of its exponential growth in complexity. _______________________________________________ clamav-users mailing list clamav-users@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
