slow name resolution on 8.2, any ideas why?
|
|
|
| Hi,
I recently setup an 8.2 machine and when doing initial name resolution
it seems to take a long time.
This is my current resolv.conf file
domain grandprixsw.com
#search f1.grandprixsw.com grandprixsw.com
nameserver 10.0.0.1
nameserver 4.2.2.2
nameserver 24.52.223.218
10.0.0.1 is a dns server on my local network which is the domain
grandprixsw.com. The other two are the dns servers supplied by my isp.
10.0.0.1 has all of the entries for the machines on my local network,
and forwarders that mirror the other two nameserver entries.
In this current setup I get quick nameresolution for external domains,
but I cannot refer to my internal machines simply by the machine name.
I can reach them by using machinename.f1.grandprixsw.com. I realize
that I can make entries for these in my hosts file but don't want to
given that everything should work correctly based on the info in the
dns on 10.0.0.1.
If I uncomment the search line in resolv.conf I can refer to my local
machines by only their machine names, but resolving external domain
names takes about 5 seconds.
The DNS server is a Win2k machine, (and no running DNS isn't really an
option on the linux box). These problems are non-existent on my
windows machines. They all refer to 10.0.0.1 as the primary dns with
the other two as alternates. All name lookups occur immediately.
Any idea of what is improperly configured on my Linux box?
Thanks in advance, Derek
P.S. After looking at this some more I don't think the search line is
the cause of the problem. It still happens when I pick a new domain.
Could this have something to do with domain name caching somewhere?
