Re: Why can't I reach master ?
John, the route is breaking down in the middle so it looks like
different routing rules are being triggered on hosts out of your control
(which implies that it's not your routing setup). Are you *sure* that
you're sending to the same address? Check the IP you're using on both
machines for master: DNS, /etc/hosts, NIS, ..., whatever nsswitch.conf is
calling out on hosts line; if you're using DNS, check that resolv.conf
is pointing to trusted servers or that zone file sources are correct if
you're running a private named.
I get 209.41.108.5 doing a "ypmatch master.debian.org hosts.byname" which
refers to a private (caching) server which refers to *.root-servers.net.
for external lookups.
Using nslookup, I get the following name servers for debian.org (from
{a|b}.root-servers.net):

Ok, all the others, except ns2.cistron.nl seems to have consistent IP's
known across multiple root-servers (had to check because I was having
problems with getting *any* response for debian.org domain as you'll see).
Ok, doing lookups on samosa - no response:
> server samosa.debian.org
Default Server: samosa.debian.org
Address: 209.249.97.234
> master
Server: samosa.debian.org

Ok, trying saens:
Same thing - not good. Where did my lookup come from? Trying other
debian name servers. Ok, got an answer from open.hands.com. (samosa and
saens may be up but may have my queries blocked - i.e., this may be a
security issue rather than an availability issue - maybe).
Ok, results from open.hands.com:
> server open.hands.com
Default Server: open.hands.com
Address: 195.224.53.39
> set domain=debian.org.
> master
Server: open.hands.com
Address: 195.224.53.39
Name: master.debian.org
Address: 209.41.108.5

However, I was just trying to confirm the IP above comes from a trusted
source, but you should probably do that yourself anyway (unless you
trust me :-)).
Ok, that done, you need to make sure that when your machine resolves
master, it gets this address, or upload to an IP address if your upload
programs/scripts can do that.
