83.142.82.2, eh?

I'm in Austria, so this is a server I get sent to quite often. Recently,
I had problems with 83.142.82.2 and .7. I've filed a support ticket
about them and once it was answered, .7 was up and running again (ping
and stuff too) but .2 was still ignoring me completely (be it a SYN to
TCP port 27030 or an ICMP echo [= ping]) and it still is doing so now.

This leads us to two possibilities:

1. 83.142.82.2 is doing filtering of both TCP and ICMP echoes (which
means that if you're not on the "allowed" list, you won't get answers to
ping... which is bad. I doubt you can pull of a DoS using ping and
network diagnosis possibilities are a Good Thing™). In that case, the
filtering is done wrong, since I get elected for .2 and the server
doesn't let me in.
2. 83.142.82.2 is simply down. In this case, I'd beg the person
responsible for content servers to try diagnosing the problem or calling
CS-Arena to give the box a cold start.

Anyway, good that this is getting some mailing list coverage. I find the
support site kind of... too impersonal.

P.S. Drop me a line if I should try pinging or connecting to .2 for
diagnostic purposes.

hi valve,

again, our steam content server is not correctly handled by the SCS
network.
when i set up a fresh steam game servers and use
"PreferredContentServerIDs = 10,10,10" in the Steam.cfg file, the steam
update is requested from 83-142-82-2.cs-arena.com which is a filtered
server so this request will end in a timeout:

   ./steam -command update  -game "Counter-Strike Source" -dir .
   Checking bootstrapper version ...
   Getting version 18 of Steam HLDS Update Tool
   No Steam Content Servers available, please try again later

We already had this problem in September and now history repeats itself.
I'm really sick and tired of requesting support for our content server
that basically reduces the bandwidth load on your network and i wonder
why a company like valve seems to be unable to fix such a simple
problem. As a matter of fact, we are currently unable to update our
steam servers as all requests run into pseudo-firewalled content servers
from cs-arena (basically, request are not blocked as they should, the
are kept in SYN SENT state and wait until their own timeout limit
terminates them).

To Do for Valve (especially Mike Dunkle):

1. tell cs-arena.com to properly block their content servers
2. check content server id #10 if this is set to 80.190.65.199,
80.190.65.200 or 80.190.65.201 (we accept connections on all three IPs).


Hopefully, this is the end of a never ending story. If not, we will shut
down the steam content server, it makes no sense to run a dual opteron
with 8 GB RAM that simply does nothing.
