Not able to connect to machine using name

makam.sreekanth · 01-15-2009, 05:52 AM

Hi,

I have installed weblogic (some Application server)under my Linux box. To open the console, I have to goto "http://<machinename>:7001/console".

If I use "localhost" in place of machine it work fine but if I use machine name it will not work. I tried giving with domain name, IP address. What ever I try the console will not open. In fact explorer gives me an errors saying "connect refused while contacting the box"

Please let me know is anywhere I need to configure so that I can use machine name.

Completely stuck with this, quick answer is most appreciated.

It is not able to resolve to name most probably. You need to edit hosts file under /etc.

/etc/hosts

<IP Adress> <MachineName>

For Example:

10.14.236.134 BL987FRT

Now try pinging to the Machine by name and it should be able to connect to the machine

Thanks a lot for both for your quick answers,
I have 2 questions here...
1. After changing hosts file,Do i need to run some command or restart some service. Please help me with steps.
2. I need also to access from different machine. Please give which file to edit for this.

Each client machine needs to know how to contact the other box. It uses the /etc/hosts file to translate from a hostname to the ip address, as mentioned by your_shadow03. This is the /etc/hosts file on each client machine, not the server. Each client machine could theoretically know the host by a different name, but that would get too confusing for me at least.

As far as I remember, you don't have to restart anything to get it to recognize a new host.

Yeah you will have to edit this file on each machine on the network so that they can resolve the names to the corresponding ip addresses. You can have a dns server for this and this can be one time thing for you so quite less tedious. You do not need to restart or reload any service after editing the file.

Thanks for all your help. yes /etc/hosts helped me in resolving this.
The main issue I facing was, I had 2 network interfaces and the machine name is mapped to ip1. but the server was running in ip2. This was the conflict. After changing the hosts file to point the machine name to ip2, everything started working fine.
