A non-unix tcp/ip station on our network is setting
its tcp MSS(maximum segment size) to zero causing a flood of
zero length data packets onto the network from Sun and other
BSD based-stations. It looks like the BSD code doesn't check
if the MSS is being set for zero and tries to send zero length
packets out.
I have a few questions:
1. Is it acceptable to set the MSS to zero ?
If not what should be the minimum value ?
2. If not acceptable, can the host decide not to send any data
and close the connection ?
3. How are the non-BSD implementations deal with it ?
Thanks in advance for any suggestions.
