 |
|
I'm able to ping another pc on my network,
but not a pc on the internet.
example:
If I ping www.gentoo.org, I get the following message:
then nothing happens and when I press control + c,
I get the following message:
| Code: | --- www.gentoo.org ping statistics ---
2 packets transmitted, 0 received, 100% packet loss, time 1017ms
|
how does this come?
I am using a router to connect to the internet,
and under Win XP everything works correctly. |

er.. yea.
some servers on the web discard any ping attempts, so you won't get any replies from them. the server you pinged (gentoo.org) wont reply becuase it's set to do that.
however, ping something like yahoo.com or google.com and you'll get a reply.
don't think your computer is broken becuase you dont get a ping response from gentoo.org  |

gentoo.org does not respond to pings, but www.gentoo.org does.
| Code: | $ host www.gentoo.org
www.gentoo.org has address 198.63.211.235
www.gentoo.org has address 203.112.31.164
$ ping -c 5 -q 198.63.211.235

Agreed, its simply filtering icmp echo requests. If your attempting to vrfy wether or not a host is up (one that you suspect is filtering these requests of course) try:
nmap -P0 www.whatever.org
