It is always helpful for guys around to help you if they know what distribution you are using.
You might not have configured your network card properly.
If you are sure your distro has detected and installed the card use the command ifconfig to see the configuration.
If you are using red hat linux use system-config-network to configure network and assign ip address, netmask and other details.
If you are using Ubuntu, you can do it graphically.
go to System > Administration > Network and complete the network details.
Other distributions can also configure your network graphically more or less the similar way.

Is it a so called SERVER of your or a Real SERVER out there?

If its a Real LAN server, I had the same problem of connection time out and connection refused... messages... I don't know how, this problem vanished itself and now I am able to connect to my LAN w$indows server using Fedora.

But my observation is, it was a server side problem ..... Now It accepts my connection and I surf.

Can you ping your server when your Firewall is disabled??

if no then it may be a server side prob.

Cheers!!

Hmm.. It seems like you are in exactly a situation I have been through..

Could you please elaborate some more?

Do you want to share you internet connection using tow LAN CARDS? if yes do you have a Crossed Wire Cable?

There is not limitation to write in detail.. so please feel free to discussing in detail.. I hope we, together can sort it out..

Cheers!!

C:\Documents and Settings\Raj>route -n

Manipulates network routing tables.

ROUTE [-f] [-p] [command [destination]
[MASK netmask] [gateway] [METRIC metric] [IF interface]

-f Clears the routing tables of all gateway entries. If this is
used in conjunction with one of the commands, the tables are
cleared prior to running the command.
-p When used with the ADD command, makes a route persistent across
boots of the system. By default, routes are not preserved
when the system is restarted. Ignored for all other commands,
which always affect the appropriate persistent routes. This
option is not supported in Windows 95.
command One of these:
PRINT Prints a route
ADD Adds a route
DELETE Deletes a route
CHANGE Modifies an existing route
destination Specifies the host.
MASK Specifies that the next parameter is the 'netmask' value.
netmask Specifies a subnet mask value for this route entry.
If not specified, it defaults to 255.255.255.255.
gateway Specifies gateway.
interface the interface number for the specified route.
METRIC specifies the metric, ie. cost for the destination.

All symbolic names used for destination are looked up in the network database
file NETWORKS. The symbolic names for gateway are looked up in the host name
database file HOSTS.

If the command is PRINT or DELETE. Destination or gateway can be a wildcard,
(wildcard is specified as a star '*'), or the gateway argument may be omitted.

If Dest contains a * or ?, it is treated as a shell pattern, and only
matching destination routes are printed. The '*' matches any string,
and '?' matches any one char. Examples: 157.*.1, 157.*, 127.*, *224*.
Diagnostic Notes:
Invalid MASK generates an error, that is when (DEST & MASK) != DEST.
Example> route ADD 157.0.0.0 MASK 155.0.0.0 157.55.80.1 IF 1
The route addition failed: The specified mask parameter is invalid.
(Destination & Mask) != Destination.

Examples:

> route PRINT
> route ADD 157.0.0.0 MASK 255.0.0.0 157.55.80.1 METRIC 3 IF 2
destination^ ^mask ^gateway metric^ ^
Interface^
If IF is not given, it tries to find the best interface for a given
gateway.
> route PRINT
> route PRINT 157* .... Only prints those matching 157*
> route CHANGE 157.0.0.0 MASK 255.0.0.0 157.55.80.5 METRIC 2 IF 2

CHANGE is used to modify gateway and/or metric only.
> route PRINT
> route DELETE 157.0.0.0
> route PRINT

as requested earlier in this post by chipotphe? Thanks.
