RE: Localhost problem!!

Hi everyone!!

i tried all three but it still doent work!!

there's one point i wish to be clear upon.
when the system boots up the Ethernet card (or the NIC) detects the IP
address assigned to it BEFORE it knows whatever hostname is assigned to
it. am i correct??
what i am trying to understand is that /etc/hosts
a) provides the machine with the corresponding IP addresses of various
hosts which may be refernced from time to time
b) provides the hostname for a given IP address
c) Both a & b

this is getting a bit confusing for me now. 

If I change the hostname from localhost.localdomain (which has an alias
localhost) to say "ABC" while retaining the alias as "localhost" would i
still be able to reference the machine as localhost or would i need to
look for "ABC" on my N/W. This is important to me as when i try to
access the swat or http/https service running on my machine from some
other machine say "M" i cant say http://localhost:80 or
http://localhost:901 or https://localhost:443. For all i know or rather
dont know, that machine M might itself be running a web server (or even
the same web server) and then which one gets accessed?? 

I am sorry if i am confusing anyone but i really need a hand with this
jumbled up problem.

Thanx to evryone in advance (especially vava and yashpal)

a lot of things could go wrong here..
i'll list a few

firstly ofcourse asyou said,
1. try putting localhost in your /etc/hosts file. andyou are
right, you are browsing a service on your computer (swat that is..) and
you neednt have the internet connection at this point of time...
2. maybe your swat is not enabled... open /etc/xinetd.d/swat and put
"disable=no". you could then restart xinetd... but then, the easier way
ofcourse is restart the machine... (yeah i know its the wrong to learn..
we should get one thing right at one time...;)

(xinetd would be on your system, if you have RH7.x or greater... earlier
versions have inetd as explained by another response to your request..)

3. one more point that i can remember is that its port 901... so you
need to
give http://localhost:901/ in your browser.. "along with the port

try these out...
it should work.

Hi everyone!

I have RedHat7.0 with samba installed. But when i try to start up swat
or enter the text: http://localhost into the Netscape address bar i
receive the following response (rather an error message):

" Netscape is unable to locate the server keyword.netscape.com. Please
check the server name and try again."

Also received with this is another message in the background:

" Warning: the following hosts are unknown:
This means that some or all the hosts will be unreachable.
Perhaps there is a problem with your name server?
If your site must use a non-root name server you will need to set the
$SOCKS_NS environment variable to point at the appropriate name server.
It may (or may not) be neccessary to set this variable, or the SOCKS
host preference to the IP address of the host in question rather than
its name.

Consult your system administrator."

(*My guess is that Netscape is unable to resolve the hostname to IP

Please note that i am able to access our intranet sites allright. Also
the preferences are set to: "direct connection to the internet" (though
i dont have a direct connection to the net). I dont think this would
affect the localhost refernces. am i correct??

Please help me as i still a novice to LINUX.
