[Opensim-dev] Checks on legitimate external services used by Robust.exe or OpenSim.ini

[Ai Austin]

I have been checking firewall settings on our grids and the machines 
which run them, and looking at established port/service connections 
on each.  have found a few I do not recognise, but some of these I 
can guess at.  It would be helpful if we coud get an explanation of 
the three involved if they are meant to be legitimately used in Robust/OpenSim

-----------------------------
Robust.exe is using 84.60.114.238:35201

Name:    dslb-084-060-114-238.pools.arcor-ip.net
Address:  84.60.114.238

-----------------------------
OpenSim.exe is using 28.237.157.136:6667

Name:    HUBBARD.CLUB.CC.CMU.EDU
Address:  128.237.157.136

6667 which is an IRC port I believe.  Yet we are set to use 
irc.freenode.com. This may not be an issue as freenode distributes 
traffic over contributed servers I think.  But given this is the "CMU 
Computer Club" (http://www.club.cc.cmu.edu/) I thought I would check 
if there is any known issue here.

-----------------------------
OpenSim.exe is also using .130.126:80

Name:    ec2-75-101-130-126.compute-1.amazonaws.com
Address:  75.101.130.126

This may be the Amazon computing cloud.. and may relate to map 
serving?  Anyone know what is going on here?  I am not using OS-Maps 
or any map module that is not just serving map s from ou own servers 
as far as  know.
