Sure. The time between retries is variable, it starts out as a few seconds (think, three), and backs off exponentially for a variable number of tries (/proc/sys/net/ipv4/*retries*). It comes out to a pretty large number, a minute or two typically. You really don't want to depend on any of this however. TCP will use all sorts of information from other connections, routing table entries and congestion algorithms, etc to be as adaptive as it feels it needs to be. Constants are NEVER a good idea in networking. Why wouldn't you just leave the timeout to TCP, and make CM's infinite?
