---+ How to enable DNS on the HP3000

Enabling DNS (requires MPE/iX 4.0 or above): 

If your system is already network connected, ideally all you need to do is create a !RESLVCNF.NET.SYS file (you can use the template !RSLVSAMP.NET.SYS as an example). Remember the tags in the file are case sensitive...

Specify your domain name (acme.com)
Specify at least one nameserver - if you have more than one nameserver, repeat the nameserver line once for each entry. For example:
<pre>
domain hp.com
nameserver 10.1.1.2
nameserver 10.2.1.2
</pre>

Once you have created the !RESLVCNF.NET.SYS file, you'll also want to create a symbolic link file to it so Unix/Posix applications can also utilize DNS. To do this, type the following as MANAGER.SYS

<pre>
:NEWLINK /etc/resolv.conf;TO=/SYS/NET/RESLVCNF;SYMBOLIC
</pre>

Once you have created the !RESLVCNF.NET.SYS file (and the symlink from /etc/resolv.conf) your system will immediately start using DNS to resolve hostnames.

On the other hand, if your system has never been setup to talk over a wide area network, you can follow all these steps:

(1) Insure you have Ethernet and ARP enabled in NMMGR on the link. This flag is in the "!NETXPORT.NI.niname" screen. 

(2) Edit RSLVSAMP.NET and HOSTSAMP.NET to fit yourself and save them as !RESLVCNF.NET and !HOSTS.NET accordingly. You must define your nameserver's IP addresses in RESLVCNF and you can define more than one. 

(3) In NMMGR, define "Default Neighbor Gateway" to point to the router. This is on the "!NETXPORT.NI.niname.INTERNET.gatename" screen and you should have the IP address of your router (or gateway), and in the table of "reachable networks" you want an IP address of "@". This gateway address must be on your local IP network unless you have some other gateways or proxy services going. 

(4) Be sure to fill in your "real" ARPA Domain address in NMMGR even if it is different from your "probe" name. The probe name is in the main screen after you open the config file. The ARPA domain name is in the initial NS configuration screen. THIS MUST MATCH YOUR DNS INFORMATION. 

(5) Always establish Internet connections by the ARPA domain name. Unless you've made some extensive and unnecessary manual directory creation to make the names accessible, using the probe name will fail (unless, of course, the two are the same). 

At this point if  I think you will need to completely stop and restart your network services; I don't think all of these changes can be applied by a NETCONTROL UPDATE (but I could be wrong!).
