Linuxconf makes a small check with the DNS before trying
to further configure the machine. It probes the DNS and wait
for 4 seconds. It then reports an error if the DNS has failed
to answer within this period. Here are different ideas 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 you (network wise), you are better
off setting up a caching DNS on your machine. Linuxconf does
this automatically 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 quickly.
- DNS do not fail often. When something is wrong there, the
effect is so pervasive, that the user believes his machine is
either hung or broken.
