I use a fairly short 2 hour established timeout on firewalls I operate,
which works fine for most purposes. Occasionally, however, it would
be nice to have a longer timeout for *certain* types of traffic
such as SSH or telnet sessions.
So, below find a TIMEOUT target to enable such per-conntrack timeouts.
Syntax for SSH would be something like:
iptables -A foo -p tcp --dport 22 -j TIMEOUT --timeout 123456
iptables -A foo -p tcp --dport 22 -j ACCEPT
It could of course also be used to lower the timeouts on some traffic,
such as HTTP.
I think the patch is useful, but I wonder how long it will take until
people want to override timeouts for other connection states. I'm
also looking for a way to pass parameters for new connections to
helpers (most of the things that are currently module parameters),
so maybe we could generalize this to a conntrack parameter target?
