FASP session starts

When the FASP session starts the program outputs some national information:

LOG FASP Session Start uuid=a9063e44-f785-4bca-8e71-3eaa20a64b32 op=recv status=started source=aspera-test-dir-large/1GB (1) dest=/tmp source_prefix=- local=130.237.209.248:42132 peer=198.23.89.123:33001 tcp_port=22 os="Linux 3.7.10-1.45-desktop #1 SMP PREEMPT" ver=3.5.4.103990 lic=6:1:1 peeros="Linux 2.6.32-504.3.3.el6.x86_64 #1 SMP W" peerver=3.5.4.100392 peerlic=10:1:22001 proto_sess=20002 proto_udp=20000 proto_bwmeas=20000 proto_data=20008

Transcript

So it output this log information, and the session started, and we get some additional log information, and we see that the initial path MTU was 1492 bytes and the starting estimate of the round trip time was 174 milliseconds - since the site was located in California and I was running this on a machine here at KTH.
