In the past few days I encountered an MTU problem on the Internet - some
incompetent admin seemed to have set a low MTU on their router *and* prevented
"can't fragment" messages from being sent from it. The result was my SSH
tunnel
kept stalling when the route happened to use that particular router. I fixed
the problem by lowering the MTU on my dial-up PPP connection.
I have also had problems with stalling connections under other circumstances,
but I don't think the kernel or MTU are responsible - yet!
