Sir,
I'm a new user of linux.I'm having RH 7.2.
from my machine i can able to ping own ip but i cann't able
to go outside .
i have given following commands :-
51.0.140.11 is a router or dsl modem or something that your computer is plugged into?
Does your NIC show a link light when you connect it to the network? Do you see the activity LED blink at both ends of cat5 cable when you ping?
it is a mrtg server.
NIC led is glowing.
corresponding switch LED is also glowing.
so far is cat-5 cable is concerned ,it is tested
because other machines are working with
this cable.
You might take a look at my last post on the thread I initiated in "Linux newbies" forum : "Problem with ethernet/internet". I solved the problem and the whole thread itself is interesting. Hope this helps
Nmap run completed --256 IP addresses(1 host up) scanned in 19 seconds
#nmap -sS -O 51.0.140.11
21/tcp open ftp
21/tcp open ssh
21/tcp open telnet
21/tcp open sunrpc
21/tcp open kdm
No exact OS matches for host (If you know what OS is running on it, see http://www.insecure.org/cgi-bin/nmap-submit.cgi).
TCP/IP fingerprint :

T1(Resp=Y%DF=Y%W=7FFF%ACK=S++%Flags=AS%Ops=MNNTNW)
I'm sorry, I posted that in error. It should be this:
nmap -sS -O 51.0.140.6
But it seems your gateway did not respond to the ping sweep. What I mean is when you did this: nmap -sP 51.0.140.0/24 you should have seen at least 2 hosts up.
