nslookup & hosts

Jie Li — Fri, 08 Oct 2004 11:47:47 GMT

It looks like after I added dns, the nslookup isn't working, and somehow it wouldn't look up in the hosts file.

lpstat -o
lpstat: HPDPS error (Cannot determine the local IP address.)

nslookup xxx.xx.xx.xxx
*** Unknown source : hosts. Not Supported
*** You have defind one or more supported sources.
*** Please modify your configuration file and try again
*** or you will get unreliable information.
No name server/service(s) responding.

Thanks

Your problem is on /etc/nsswitch.conf there.

hosts: entry there.

hosts: dns files ldap ...

I hope you have defined two hosts: information there?? check there.

cat /etc/nswitch.conf --> to forummers

HTH.

what is there in /etc/resolv.conf and /etc/hosts files there.

It will give dns / files hosts informations there. Post those entries too.

That's what I suspected frm the error you got. The nsswitch.conf file should look like this:

hosts: dns [SUCCESS=return NOTFOUND=continue UNAVAIL=continue TRYAGAIN=continue] files

(The directives between the [] just guarantees that all programs, regardless if they were linked with libc.1 or libc.2, resolve the same way.)

One possibility is if you are versioining with DNS files, you have lock out the file properly increamenting the serial number of for changed entries in respective file. Have you dont it properly.

co...It is something like that..Am I correct.

Sorry, also you have restart your named using the script. And update the caching server for having latest updates. Also push the entries on zoning servers too..

Thanks
