SOCKS flood #834

Description

@PeterSurda

Apparently, SOCKS (e.g. Tor) can get overloaded by syn flood. I haven't experienced this but people reported it in the general chan. One suggested solution is to reduce maximumNumberOfHalfOpenConnections when using Tor. Another one is to increase MaxClientCircuitsPending in torrc.

Apparently, this can happen on Tails, the suggestion is "either remove IsolateDestAddr and IsolateDestPort or increase the MaxClientCircuitsPending but consult the manual first."

Maybe PyBitmessage can try to detect Tor config and adjust accordingly. Apparently Tor has a RPC so maybe this can be used for this purpose.

Having a large number of half-open connections is considered abuse of Tor.
