Yep, it's rediculous (sic).
Unfortunately Ethereal can't quite do this either. So, please write the code
to do this!(it has been noted more than once on the development list that
this feature is needed.)
In the mean time in Ethereal you can use a byte-wise display filter on the
IP packet (only works nicely if the mask is 8, 16 or 24 bits. "ip[12-14]==
0a:01:02" will match source IP addresses 10.1.2.x
(It is an exercise for the reader to figure out destination address lookups
and other masks)

Subject: [Ethereal-users] Sniffer Pro vs Ethereal
Hi all,
Can I get some input on the above subject as far as 'quality' and ease of
usage. Also, I have the below question if anyone could help. I know it's
not Ethereal related, but I'm desperate.
#########################################################################
Can you filter a subnet on a sniffer pro?
I'm using sniffer pro 3.0 on NT platform. I am able to filter a single
host or any host. But I cannot filter a subnet, for example,
10.10.10.0/24. I have tried entering in all sort of combination such as:
10.10.10.*
10.10.10.*.*
10.10.10.0/24
10.10.10.0 /24
10.10.10.0/255.255.255.0
10.10.10.0 /255.255.255.0
10.10.10.0 255.255.255.0
10.10.10.any
10.10.10.
10.10.10.0
What am I missing? Or maybe this sniffer software doesn't support a
subnet filtering? If that's the case, then it's rediculous. Because it
does support 'any' which is everything.
Thanks for any input.
