Hi all,
Thanks to everyone who replied to me.
Original post is included at the end of this mail.
* Decided that it was a 3rd party app calling ifconfig. Added an ifconfig
wrapper to log ifconfig usage.
* Removed extra entry from /etc/netmasks.
* Rebooted machine.
After reboot watched the logs and saw something change the NIC. I am in the
process of hunting down the s/w thaat did it.
Regards,
Simon.

Hi all, We have a Sun system whose broadcast address changes occasionally from a Class C broadcast address to a Class B broadcast address. I.E from 172.17.2.255 to 172.17.255.255. I have entered this (See below) into the /etc/netmasks to try and keep the broadcast address on track, but because the address mysteriously changes during normal day-to-day operation and the /etc/netmasks is only (I think?) consulted at during boot time, the broadcast address still changes. $ cat netmasks 172.17.0.0 255.255.255.0 172.17.2.0 255.255.255.0 172.17.0.0 255.255.255.0 172.17.3.0 255.255.255.0 $ ifconfig -a lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2 inet 172.17.2.64 netmask ffffff00 broadcast 172.17.255.255 ether 8:0:20:b2:f4:27 hme1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3 inet 172.17.3.64 netmask ffffff00 broadcast 172.17.255.255 ether 8:0:20:b2:f4:27 $ showrev Hostname: trecsk-ctl Hostid: 80b2f427 Release: 5.8 Kernel architecture: sun4u Application architecture: sparc Hardware provider: Sun_Microsystems Domain: cl.gemini.edu Kernel version: SunOS 5.8 Generic 108528-03 August 2000 $ uname -a SunOS trecsk-ctl 5.8 Generic_108528-03 sun4u sparc SUNW,UltraSPARC-IIi-cEngine Has anyone seen this before, or can anyone think of a process that would change this?
