Re: NameService and getHostByName()

Hi Darren,
thank you for your answer.

Unfortunately nothing changes removing the '='.
The only way to solve my problem is to add the IP
address of the machine in /etc/hosts (I would like to
avoid to do this).

It seems the NameServer always tries to resolve the
hostname to get the address, no matter what parameters
you specify on the command line.

Any ideas?

Cheers,
Alessandro
