Solaris

How do you fix a Host not resolvable error when visiting a website. Thanks

You need to be more specific about yuor issue. This is a Unix box? Which o/s?

URL's in browsers need to be resolvable. Do to that your machine must know where it's DNS server(s) is and probably also need to know the IP of it's gateway in order to get to the DNS server.

Post more info please.

Is the site working externally and also internally? or one of the other

This is a unix box running solaris 10. i know where the DNS server is and also its ip. I just need help with what the steps and what commands i should be using. The site works when using a computer outside the enterprise.

Thanks in advance

Okay, I see your reply post.

Firstly, I'll cheat and give you this link to save me some time:-

Solaris UNIX: How to Setup DNS Client configuration / name server

The files are:-

/etc/hosts which will resolve local stuff (your subnet and LAN)
Lines contain an IP address followed by a host name

Further afield the system looks at resolv.conf
Lines contain the word "nameserver" followed by an IP address.
There can be multiple lines ie. multiple DNS servers.

For this to work the file:
/etc/defaultrouter should tell your system where the gateway is to get out of your LAN.
One line contains just an IP address. Nothing else need.

With the above your system should know how to get beyond your LAN and one or more DNS servers to send resolution requests to.

Hope that helps.

Forgot to say that some of these files may not exist after a raw install. Just create them with an editor and populate them as described.

resolv.conf also resides in /etc

In addition to hicksd8's excellent post, also read up on the nslookup and traceroute commands.

Thanks Hicks
