what is a lame server?

[Michael Kjorling]

Anyone volunteering on writing a FAQ?

A lame server is a server which is pointed to in a domain (zone)
delegation record, but it doesn't answer authoratively for that zone.
Quite simple yet a very common error.

And a _very_ common question on this list/newsgroup :-)

I have had a few log messages that say lame server on 'www.xyz.com'
Any idea what it means?

You ignore it. And possibly send the log messages to /dev/null.

How do you fix the problem?

How do you fix the problem?

If it isn't one of your domains don't worry about it,
someone else around here will bother them soon enough,
unless you have some sort of additional sway with the
administrator of the domain the lame server is in, in which
case do hassle them.

Michael must know by now that BIND has an FAQ on the ISC
site, but it doesn't mention LAME servers *8)

Fortunately whole chunks of the DNS Resource Directory have
been dedicated to lame servers, as well as RFC1912.

http://www.dns.net/dnsrd/docs/

The error also occurs where certain gaps appear in the DNS
reverse lookup, the fix here is to get the reverse lookup
set up correctly.

PS: Is anyone routinely running "lamers" or similar these
days..... I saw the DNS spring cleaning project....

How do you fix the problem?

You contact the administrator of the zone and ask them to
fix it.

If it is your zone, you need to work out the underlying cause.
e.g.
bad delegation (wrong machine listed in parent/child NS
RRset)
bad master file (master server lame)
bad IP address in named.conf (slave server lame)
bad access control list (slave server lame)
missing entry in named.conf (slave server lame)

Yes, Simon, indeed I do. :-) Only that I haven't looked at it myself
in too long it seems.
