Subject: [osol-discuss] Looking to limit SSH brute force connections

I have recently setup OpenSolaris to use as a file server (I like ZFS) and I
connect to this server remotely using SSH. In the past I used iptable rules on
Linux to limit connection attempts to SSH within 60 seconds to 4 attempts.
This eliminated the Brute Force attempts at guessing userids and password, or
at least drastically limited them.

I have been looking at ipfilter which is available for OpenSolaris, is this the
right tool to limit these login attempts in the same manner as I did with
iptables or is there a better option on OpenSolaris? While I have found some
information on writing ipfilter rules I have not found any examples for
limiting SSH login attempts. At least nothing solid that I am certain I can do
on OpenSolaris. Thanks in advance.
