[Wien] w2web interface not launching from web browser

[Ushma Ahuja]

Dear Wien2k users,

I have installed Wien2k_13 in an intel core I7 machine with Red hat Linux 5.5
I did the site configuration with root login and then did the user configuration for the local user. 
On installing w2web in the local user, the respective directory files are all generated successfully in Wien2k's folder but I am unable to access the w2web interface through the web browser
 (I am using Firefox). I keep getting the "server not found" message. Also, I get the following message on the terminal. On removing the w2web directory and on re-installing it, I am again getting the same message.

[ahuja at localhost ~]$ w2web

Checking for Installation in /home/blahuja/.w2web/localhost.localdomain

hostname: Host name lookup failure
w2web failed to bind port 7890 - port already in use!
You may want to try w2web -p portnumber


I also tried to create a ssh tunnel and got the following message:

[ahuja at localhost Wien2k_13]$ ssh -fNL 2000:localhost.localdomain:1244 user at localhost.localdomain
ssh: localhost.localdomain: Temporary failure in name resolution
[ahuja at localhost Wien2k_13]$ ssh -fNL 2000:localhost.localdomain:1244 ahuja at localhost.localdomain
ssh: localhost.localdomain: Temporary failure in name resolution

I have tried executing some scf cycles for sample TiC from the terminal just to check on the proper installation of Wien and they seem to be doing fine. It is only the w2web interface I can't access right now.
Any help would be great!
