System: NetBSD snert.pilhuhn.de 1.1 NetBSD 1.1 (SNERT+PPP) #11: Thu Jan 30 11:00:49 MET 1997 hwr@snert.pilhuhn.de:/usr/src/sys/arch/i386/compile/SNERT+PPP i386


>Description:

netstat does not print the netmask that comes with a route. for
claasfull routes this does not matter as netstat does the right
thing and only displays the part of the destination address that
is needed.

For CIDR adresses this fails.

>How-To-Repeat:

# route add 10.1.2.3 -netmask 255.255.0.0 snert
# route add 10.1.2.3 -netmask 255.255.128.0 pilhuhn

# netstat -r | grep 10

10.1             pilhuhn.de         UGS         0        0      -  ed0 =>
10.1             snert              UGS         0        0      -  ed0


With my hack below this gets:

snert# ./netstat -r | grep 10
10.1             /17 pilhuhn.de         UGS         0        0      -  ed0 =>
10.1             /16 snert              UGS         0        0      -  ed0

This seems to apply to all versions - not only to 1.1/i386

>Fix:

Something like:

Formatting is very bad, but I think you'll get the point  ...
