Hi,

config files seem ok.
Googling around it seems somebody also experienced similar issues; not clear if and how they cleared the problem though..

First thing you could try to exclude problems with the internal nameservers you are using.
If you can, try reproduce the problem by ping/nslookup to an external site (i.e.: www. google.com).
If the above can be done, try also to use some external dns server (i.e. opendns) and repeat the test against an external host (i.e. www. google.com again).

If you can execute the above tests and if the results of the above tests replay the problem already posted, we can exclude a problem with internal dns servers.


Next thing I could suggest is verifying the shared libraries used by nslookup and by ping:
this can be done by:
- looking for the full paths to nslookup and ping:
Code:
which nslookup
which ping

- then listing the shared libraries to check for problems:
Code:
ldd -v /path/to/nslookup
ldd -v /path/to/ping

and verifying that the required libraries are actually available (in particular, the libdns* and libresolv* ones).

I may also suggest the following forum:

the user ScYcS experienced similar problem, you could contact her/him directly to kow if and how he cleared the issue.

see ya
