[ILUG] dhcpd/bind/lookup problems

[Ken Guest]

Got a strange problem on a SuSE 7.1 box running as a
nameserver and dhcp server;

My dhcpd.conf is configured to always give my laptop a
specific hostname (and thus a specific ip address). This has
stopped working so now I am using "fixed-address
10.11.11.5;" instead of "fixed-address acer.technobrat.net;"
Before I changed that the laptop was being assigned an ip
address from the pool of ip addresses for 'visiting machines'.

Also, when I ssh in to that server and execute 'w' the value in
the from field (mentioning the machine that I am connecting
in from) is a dotted quad rather than mentioning the fully
qualifed name.
I reckon this is just a second symptom of whatever is causing
the above dhcp problems.

Added to this
$nslookup acer
works fine, where
$ping acer
doesn't. (a 3rd symptom I guess)
Doing a $ping edge (edge is the server's name) does work
though.

Looking in /var/log/messages:
1//   there are entries from sshd saying it could not reverse
map address 10.11.11.5 (which is the ip of the laptop as now
explictly assigned in dhcpd.conf)
2//   there are "sysquery: nlookup error on ?" entries from
named

Does anybody know what is going on here and how I should
resolve these issues?


thanks

Ken
