Description of problem:
In the ssh utilities, IPv6 addresses need to be enclosed in square brackets "[]". The man page specifies this in descriptions of port forwarding options (-L, -R. -D), but there is no other indication of this requirement.


Version-Release number of selected component (if applicable):
n/a


How reproducible:
Always.


Steps to Reproduce:
1. man ssh
  
Actual results:
Initially the customer thought IPv6 was not working at all since this detail was not specified.


Expected results:
A simple "IPv6 note" in all the ssh man pages. A note could also be added for the "-6" switch description, however that option is only to force IPv6, so the square bracket necessity can apply to other cases as well.


Additional info:
I would recommend something like the following (based on the hostaccess(5) man page):

$ diff -c old new
*** old	2011-04-12 12:52:36.000000000 -0400
--- new	2011-04-12 12:53:40.000000000 -0400

       ssh connects and logs into the specified hostname (with optional user name).  The user must prove his/her identity to the
!      remote machine using one of several methods depending on the protocol version used (see below).
