Right. However for some of us, we need to keep separate systems connected
w/o IP Masquerading. My understanding is that IP Masq. adds a speed
bottleneck on the connection due to the linux box needing to process all
packets. Is this correct?
ACS has made it clear they don't want to install more than one line into a
room/suite (I've had long conversations about the policies and
implications with my CA), and this is why they were giving out hubs to
suites a year or two ago.
If eavesdrop protection were installed in all dorms, those of us who need
separate lines for speed considerations (again, assuming the processing
bottleneck) would be SOL. Of course, if DNO upgraded to 100 Mbps lines
(ACS rumors last year were that DNO is planning it), this would become a
moot point as long as the linux box configuration was fast enough. :)
The box could handle its own traffic and still be faster than using a hub
w/ a 10 Mbps connection for the systems masq'ed.
If the upgrade to the lines occurred _and_ eavesdrop protection became
standard, I could see Linux becoming increasingly important for demanding
users.
Then again, I can't imaging DNO putting eavesdrop protection on all lines,
as (last I heard) ACS policy is to use hubs in suites. Putting the eav.
prot. on all suite lines would limit suites to one system each.
Am I off base here?
So to summarize my questions/points:
- Does IP Masq make a bottleneck?
- ACS doesn't want to put multiple lines in each room/suite.
- Faster lines are _rumored_ to be in the works.
- Faster lines and fast Linux boxes w/IP Masq could be faster than
hubs and 10 Mbps lines.
- Will DNO put eav. prot. on all lines?
- What would be the implications for suites?
