Another DNS question.

[Erik P. Olsen]

I have several PCs/LapTops accessing the Internet through a wireless router 
(Linksys WRT54G). It also acts as a DHCP server presenting each connected PC 
with an IP-address. For Internet access it works flawlessly but I have other 
application which access the PCs on the LAN, such as back-up programs (Bacula).

For the last sort of applications I need to have either a static IP-address or 
an allways correct association between workstation name and its IP-address 
(/etc/hosts). It so happens that if the configuration (in terms of connected 
PCs/LapTops) remains static then the boxes get the same IP-address each time 
they connect to the router. This is, however, not allways true if the 
configuration is dynamic (many different PCs and not allways the same).

I feel that what I really need is a DSN on the LAN which is being updated each 
time a box connects to the router and gets an IP-address. I have noticed that 
some people disable the DHCP server in their router and establesh a DHCP server 
in one of connected PCs, but I don't see how that can be accomplished and what 
happens if that server is taken out of the network?

Is there a way out of this problem?
