Linuxconf makes a small check with the DNS before trying
to configure further the machine. It probes the DNS and wait
for 4 seconds. It then report an error if the DNS has failed
to answer within this period. Here are different idea supporting this
strategy.
- You should have good network connectivity with your DNS.
The DNS may be either located on the local ethernet network, or
right on the other side of a PPP link.
- If no DNS is available near your (network wise), you are better
to setup a caching DNS on your machine. Linuxconf does this
automaticly when you create a DNS with it.
- DNS problems are probably the most difficult problems
to track or identify for new users. Better try to detect the
problem soon.
- DNS do not fail often. When something is wrong there, the
effect is so important, that the user believes is machine his
either hung or broken.
