HP-UX 11netmask Problem

[KLier]

If I set the netmask of our class B net to 255.255.192.0 the system crash an I cannot reboot it. What is wrong with that mask ??

It seems this may be violating RFC 1122. Try running this first:

For 10.20:
#nettune -s ip_check_subnet_addr 0

For 11.0
#ndd -set /dev/ip ip_check_subnet_addr 0

Then assign the netmask. If this is successful, then ensure you place the command in either a start up script (10.20) or /etc/rc.config.d/nddconf (11.0).

For more information, see the above mentioned RFC or the documents in the ITRC knowledge database.
