I installed apache on my RHEL machine yesterday and found I could access it from a browser using http://. Of course, sshing using the hostname was also working.
So, I made an index.html file inside it (/var/www) and was able to view it from other computers on the network.
However, I made some changes to the index.html file today and the changes just wouldn't reflect on the web browser of other computers when I refreshed it. Finally, the browser just started saying it couldn't find the server. I tried using the ip-address instead: http:///index.html and it worked as expected. Now, I can't even ssh to my linux machine using my hostname. Does any one know what might have happened (note that all was well yesterday - the only playing around I did was update the index.html file and refresh the browser from another computer)?
