IPv6 Network subnets in PATTERNS ?

[Darren Tucker]

What are you trying to do?  Most of the things that take addresses support
IPv6 CIDR masks, eg:

$ cat test_config
Match localnetwork 2000::/8
    RefuseConnection "address matches"
Match All
    RefuseConnection "address does not match"

$ ssh -F test_config foo
test_config line 2: RefuseConnection: address matches

usually comes from bad judgement.
