why not going back to that /etc/hosts file and reedit it again ? and adjust your problem ?
it should be a text file, and you could have access to it using a shell, take a look on how to edit files using "vi" and here you go. the vi is a bit confusing to be used, but looking at some tutorial you would be able to modify the file to your needs.

The problem is not changing the file, the problem is after changing the file, i cant connect to machine.
# IP adress hostname
now because 2 host names have same IP, i cant connect.....i think it resulted in IP conflict.
Putty cant connect...not even ssh from command prompt..
so will machine rebooting will help???

aha now I understand, but if you connect using the IP address directly dosen't it work ?
There's something wrong with the target machine - evidently it's not listening for ssh clients (sshd stopped?). The purpose of /etc/hosts is to translate a hostname into an IP address. If you're giving the IP address directly, you skip that step.
There's nothing magic about /etc/hosts, and it's perfectly legal to assign multiple hostnames to a single IP address in /etc/hosts. I do it all the time, since that allows me to target services rather than machines - for example cvs.mousetech.com, svn.mousetech.com www.mousetech.com all might be the same IP. But if SVN outgrows the www box, I can move it to a different machine, change the hosts files and the clients will mostly never know the difference.
Although I should mention that /etc/hosts is only the first entry in my resolver chain and that DNS handles most of the non-critical stuff. /etc/hosts works best when only the hosts that you must be able to resolve even if DNS is unavailable are in it. That's because DNS server all machines, but you have to manually keep each box's /etc/hosts file up to date.

thanks tim for detailed explanation. /etc/hosts was not the culprit, as you said ssshd stopped...exactly same thing happened..but who did and how i don't know.
Actually, everything was going fine until i made above said changes in hosts file and that made me to think that change did that.
