ferm is a frontend for iptables. It reads the rules from a structured configuration file and calls iptables(8) to insert them into the running kernel. ferm's goal is to make firewall rules easy to write and easy to read. It tries to reduce the tedious task of writing down rules, thus … Bug #11933: ferm does not start - Tails - Tails Ticket Tracker Might be that we're hit by #11786#note-38, as ferm fails iptables complains about unknown options. Loading the xt_owner kernel module is enough to fix that. Nov 16 14:56:50 localhost.localdomain ferm: Starting Firewall: fermiptables-restore v1.6.0: owner: Bad value for "--uid-owner" option: "amnesia" Nov 16 14:56:50 localhost.localdomain Endpoint Protection - Symantec Enterprise This configuration file will cause ferm to write iptables rules to allow outgoing ssh and DNS to pass, block all UDP traffic and allow in only 2 types of ICMP messages, destination-unreachable and time-exceeded, and deny and log the rest. It looks much nicer than several lines of iptables but provides little benefit beyond that. Firewall Rule Definitions — DebOps v2.1.0-52-g6b4011c65

One serious security issue is that we don't know what software will attempt to contact the network and whether their proxy settings are set up to use the Tor SOCKS proxy correctly. Tails - Tor enforcement DNS. Tor does not support UDP so we cannot simply redirect DNS queries to the Tor transparent proxy. Most DNS leaks are avoided by having the system resolver query the Tor network using the DNSPort configured in torrc.. There is a concern that any application could attempt to do its own DNS resolution without using the system resolver; UDP datagrams are therefore blocked in order to prevent leaks. Ferment · PyPI
