Guus,
Below a segment of a log file. I am trying to analyse why the satellite link
goes down and up all the time (sometimes 10 to 15 times an hour, sometimes not
for a day.
My guess is that this indicates packet loss on the satelllite link and tinc not
really recovering from that. Where I inserted an empty line the log basically
stopped and was silent for I guess for 14 minutes? Would setting
'ReplayWindow = 0' provide some help here? The tunnel uses UDP.
Any pointers as to what I could do about this? Where to look?
