Re: TCP_RTO_MAX: 120 --> 240

If you plan to talk to Mars, it is not enough. 8)
If you do not plan to leave Earth, 60 sec is much more than enough. 8)


Another place from the same RFC:


                                The TCP specification [TCP:1] arbitrarily
              assumes a value of 2 minutes for MSL.

So, MSL is an arbitrary value selected to be realistic.

Nowadays, MSL is 60 seconds. RFC1122 is too conservative in most
of places, wrong in another ones and real implemntation fix it,
when it is necessary.
