Title: NSLOOKUP
Post by: Tyrone C. Miles on April 10, 2003, 01:57:46 AM

Hey does anyone know why when I do an nslookup against my e-smith server I get back:

*** Can't find server name for address 192.0.1.1: No response from server
*** Can't find server name for address 192.0.1.1: Non-existent domain
*** Default servers are not available
Server: Unknown
Address: 192.0.1.1

Is it that the DNS server does not allow NSLOOKUP? (For security reasons) or does my server have a problem. I am running a 5.5 server upgraded to 5.6.

Thanks for the help guys.

Oh and I am running this from my 2000 workstation and I have the e-smith server's IP's in my DNS settings on my workstation.

192.0.X.X does not belong to the RFC1918 Address Allocation for Private Internets.  If this is your internal NIC's address then you first need to change it to 192.168.1.1 or any of the other acceptable private ip addresses

See document http://www.linuxselfhelp.com/HOWTO/IP-Masquerade-HOWTO/x801.html

I don't know if this is your problem but you need to start with a "proper" ip address before you try anything further.

Good Luck

Paul

That is not the true address, I just put that down because I don't want to put my real (Internet routable) addresses on this fourm.

Sorry, you threw me off with the 192.X.X.X number.

Let's start from the begining with more information.

Are you set up as a server-gateway with 2 NIC's or just a server with 1 NIC?

Are you trying to do nslookup on your internal private ip or your external public ip?

Are you behind a hardware firewall/router?  This question can be a bit tricky because some "modems" (like the cisco 675's and others) can actually be set up as routers depending on your ISP.

Try ifconfig and see what your external ip address is.  If it falls into one of the catagories below, then you have another peice of equipment masking your external ip address and nslookup won't work properly.

10.0.0.0        -   10.255.255.255
172.16.0.0      -   172.31.255.255
192.168.0.0     -   192.168.255.255

Does nslookup work with any other ip addresses?

Try nslookup 12.254.149.181  this should come back with client.attbi.com.
