Hi Orr,
Here are a few strings of wire you can investigate and try:
1. Try changing the serial number in the zone file, and then reload the DNS server.
I've also noticed that if you were to add the NOTIFY flag in named.conf it can
help other slave servers (if any) to force a zone transfer after an update.
2. It is possible that the TTL in the zone file is slightly too long. Try lowering the
TTL number for the proper record, change the serial number, reload and then
try again after several hours.
3. I've noticed that some EU.ORG servers around the world tend to cache for the
other servers. If that is the case, and the caching servers aren't setup properly,
or their global TTL time is too long, this may result in some parts of the world
that work fine, and others that don't.
4. When performing a DNS change, always permit a change period of around 24
Hours, that should be sufficient for most DNS servers around the world.
Regards,
Nir Simionovich

Subject: A little bit OT: A very wierd resolving problem...
I've been encountering a very strange problem lately. Under .il.eu.org
there are sevreal domains (like linuxclub.il.eu.org).
Sometimes, one of the domains there is unaccessible. however, this is a
partial unaccessbility. (weird, told you!):
A) Not all the pages I tried to access get the DNS error message.
B) By removing the proxy, I usually can access the domain through web, but
not always.
C) I've had tracerouted it from abroad. In the last few minutes sevral
sites succeed to traceroute to it, and some failed.
The sites which failed, were able to traceroute linuxclub.il.eu.org, which
is defined in the same DNS file, and resides on the same computer as the
problematic domain.
Anyone might have an idea, what the hell is going here?
The DNS entry is just fine, becuase nslookup gives the right IP...
thanks in advance,
