Hi, I'm new to this group so please be gentle. Recently, we got a DEC Station 3100 running Ultrix as a demo. I want to use the resolver but I must be doing something wrong. I have a valid resolv.conf file pointing to both my primary and secondary nameservers. When I run nslookup it resolves any address that I want whether in my domain or out in the world. My problem is that when I try to use telnet or rlogin the only name resolution I get is from /etc/hosts. Any comments will be appreciated.

There should be a file /etc/svcorder with the following lines: bind local (assuming that you don't use Yellow Pages). This instructs the resolver code to use the name server, then the local host tables. nslookup does not check this file. Happy hacking....

What we would like to do is have one of our machines (I'll call it our server) running bind to get it's host information from name servers and our other machines run Yellow Pages to query our server for host information in the hope of reducing network traffic and load on the name servers. We are currently running YP on all of our machines, using the server as the YP master. The question is, do we just put the following in our server /etc/svorder file: bind yp local And have the clients with the /etc/svcorder file: yp local Will the yellow pages programs on our server get their information from bind or will they only use the /etc/hosts file? Thanks in advance for any help. _____________________________________ Brian V. Smith (bvsmith@lbl.gov) Lawrence Berkeley Laboratory We don't need no stinking signatures!

YP will only us the YP hosts file. Set up the client systems as resolver only systems. Have them set up to only query your server system. Have that set up as a caching server (or a master server if you are in control of your domain). The others are just slave servers. They needn't run named. Just make sure that have /etc/resolv.conf pointing at your server. So... Server should have bind yp Server should run named. Clients should have the same... bind yp Clients could run named as a slave system. Clients could also forgo named and just have /etc/resolv.config point to the server system. I trust I make myself obscure?

Unfortunately, when ifconfig is run from /etc/rc.local, the nameserver is not running. Therefore, it takes forever to time the bind connection out before going to the host table. One way around this is to put the actual IP number in /etc/rc.local, but this is ugly. Is there a way to force ifconfig to use the host table and ignore /etc/svcorder? Steve
