a college ask me why the icmp-mask-request support of current Linux
kernels is no longer available.
Some hints about the "why removed" are in "net/ipv4/icmp.c".
Unfortunately, ANK's comment matches not all cases:
..."It is wrong, it is obsolete, nobody uses it in any case. --ANK"...
For creating a Jumpstart server for Sun Solaris they are needed.
IPv4 address range: 10.10.0.0/16
Booting Solaris sends via rpc.bootparamd a icmp-mask-request which
isn't answered. Now Solaris is using 10.255.255.255 as broadcast
address, which isn't nice indeed.
Can someone point me to proper patches for current 2.2.x or 2.4.x
Or is it possible to catch such requests in user-space (perhaps with
2.4.x using netfilter)?
Thank you very much for help,
