I noticed recently when telneting to a Solaris 2.2 host
that things worked for a bit and then the connection
would hang and timeout. I traced it to the IP packets
coming from the Sun having the "do not fragment" flag
turned on. This stopped the packets from reaching me
because an MTU along the way was too small for the packet
and the router dropped the packet. Is this the default?
How do I change it?
--- from snoop ---
IP: Flags = 0x4
IP: .1.. .... = do not fragment
IP: ..0. .... = last fragment
(I must say NetBSD is looking better every day :-)
