They are filtering either ICMP echo or echo reply; using an LBNL/Unix
traceroute is successful the entire path.

Since Cidera is going offline again, I am in need of
seeking an alternative. Does anyone know of a non-land

I came across this one while writing dial-peers for a VoIP network that
went outside the North American Numbering Plan:

They sell a complete database for 249 (or 49/month subscription) but
also have a free tool to look up individual numbers.

We (operators) used to have a full mesh along the core

Much of that is disassembled
It will now probably be re-assembled.

Title: Adjusting TCP windows on production systems?
Is there anyone in a production environment who, as part of their system build process, adjusts the TCP receive window/MSS/etc. on production systems?
I'm dealing with a few latency issues and the MSS settings improve them, but I'm hesitant
Something must be highly broken at ATT. I have been receiving tons of
emails in response to a Usenet posting I made months ago asking if anyone
knew how to get out of att.net's private RBL.
The procedure:

CNN and Fox News personalities have been trading phone numbers.
CNN Tucker Carlson gave out Fox News's Washington bureau phone number on

Increasing it helps, particularly if both ends have the same
setting. Don't forget to enable both RFC1323 and RFC2018 support

My cursory investigations reveal there is no apparent alternative to Cidera in
the US right now. I'd be interested in talking to anyone who knows the
technology behind uplinking a newsfeed in order to replace Cidera's news
service. I'd guess there is a whole lot of infrastructure on the client

As a concrete data point:

Just as a head up - this sort of below should not be done on things like
web servers that support lots of concurrent connections - you'll eat all
your memory for sockets.

There are two policy proposals coming up at ARIN that may be of particular
interest to ISPs here that may not normally pay much attention to ARIN.
The first is 2002-3 which allows for end-user assignments of /22 instead
of /20.
The second is 2003-15 which, if passed, would provide /22 ALLOCATIONS
