Hello All,
I have a couple of E450s running Solaris 8, with one onboard hme interface
each.
For reasons I wont elaborate on here, I require to change the TCP MSS value
that is sent out in the three way tcp handshake.... typically the SYN-ACK
for a connection being established into the box, or the SYN for connections
established by (out of) the box.
The way to do this is via ndd:
'ndd -set /dev/tcp tcp_mss_max <new mss value>' on solaris < 8
and 'ndd -set /dev/tcp tcp_mss_max_ipv4 <new mss value>' for solaris 8 with
ipv4 stack
the former works as expected on solaris 2.6, but the latter doesnt give the
expected result on solaris 8, leaving the mss unchanged.
Has anyone run into this problem, and does anyone know if there is a bug on
solaris 8 associated with this.
Thanks
Mark
