RE: name resolution

["Rick Carroll" <rcarroll socketware com>]

Have you checked /etc/nsswitch.conf?
What do you get when you do:
ypcat -k hosts | grep sualco

you can also do some troubleshooting with:

getent -service=nis hosts sulaco
or
getent -service=files hosts sulaco
or
getent -service=dns hosts sulaco

Hi,

I'm having problems with name resolution.  We have several machines on 
an NIS network.  The NIS server is Red Hat 7.2, and the rest of the 
machines are all Red Hat 8.0.  Each machine has been assigned a local 
static IP address.  /etc/NIS/hosts on the NIS server looks like this:

192.168.230.200 sulaco.emeraldbiostructures.com         sulaco
192.168.230.201 ripley.emeraldbiostructures.com         ripley
192.168.230.202 jonesy.emeraldbiostructures.com         jonesy
192.168.230.203 iris.emeraldbiostructures.com           iris
192.168.230.205 kcsa.emeraldbiostructures.com           kcsa


The machines can be pinged by just their short names.  You can also ssh 
to a machine by its short name.  But if you try to point a browser to a 
machine's short name or even its FQDN, it says that the requested URL 
can't be found.  If you point a browser to the machine's local IP 
address, then you get the home page.  Some of these Linux machines, like 
ripley, are Samba servers.  From a Windows machine, in Internet 
Explorer, I can point the browser to just "ripley", and it gets there. 
But on all of the Linux machines, you have to use the IP addresses.  I 
think /etc/resolv.conf is OK since I can browse the outisde Internet 
just fine.  It's only with the internal Linux machines where we have 
problems with name resolution.  Thanks for any suggestions,



Hidong
