understanding apache 2 error message

[Ovidiu]

hello

I just found this error happens over and over again in my logfiles:

h898552.serverkompetenz.net : Jul 30 19:35:37 : www-data : unable to lookup
h898552.serverkompetenz.net via gethostbyname()

while www-data is the user apache2 runs as.

any ideas where to look?

###edit###

I edited /etc/hosts to look like this:

127.0.0.1 localhost
85.214.51.208 h898552.serverkompetenz.net

is that enough? do you have more stuff inside there?

is that enough? do you have more stuff inside there?

Yes, if the error disappeared now

Might have been a temporary problem. Please make sure you have valid name servers in /etc/resolv.conf.
