Ping command

Manny88 · 09-21-2003, 06:01 PM

david. All that returned like you said. here are my results trying to ping various websites in format of "ping URL -c 1"

Google.

Code:

--- 127.0.0.1 ping statistics ---
[root@dhcp-214-1141 root]# ping google.com -c 1
PING google.com (216.239.37.100) 56(84) bytes of data.
 
--- google.com ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

aol.

Code:

[root@dhcp-214-1141 root]# ping aol.com -c 1
PING aol.com (149.174.130.216) 56(84) bytes of data.
 
--- aol.com ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

Linuxquestions.org

Code:

[root@dhcp-214-1141 root]# ping linuxquestions.org -c 1
PING linuxquestions.org (64.179.4.146) 56(84) bytes of data.
 
--- linuxquestions.org ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

I don't know if that helps any. I get good results when I ping myself, but everything else doesn't work. I have no firewall on too by the way.

**Also someone asked me what type of ip mine is and I looked it up and it is a dhcp connection. I have the ability to change to static and bootp

ok. a little update. I just pulled up my .xsession errors in hope of something and I found something with my ping command that maybe might help us figure this out.

Code:

[root@dhcp-214-1141 root]# cat .xsession-errors
SESSION_MANAGER=local/dhcp-214-1141:/tmp/.ICE-unix/1949

I noticed the last one. Thought it might mean something.

I can ping all but AOL which has most likely disabled pings. The fact that it is giving you the IP address of the server correctly - ie "linuxquestions.org (64.179.4.146)" means that your DNS is working. This means that along the way pings are being dropped. What type of internet connection do you have? Perhaps you have an iptables rule blocking outbound pings:
iptables -L

I'm running an NIC ethernet cable connection. I can telnet fine and I can search the WWW fine. Its just that ping command thats really bugging me. I tried that iptables -L and it says command not found

adz · 09-21-2003, 07:13 PM

Iptables has to be run as root.

Manny88 · 09-21-2003, 07:22 PM

I am root when I do all this. This is what happens

Code:

[root@dhcp-214-1141 root]# iptables -L
bash: iptables: command not found

adz · 09-21-2003, 07:53 PM

It's in the /sbin directory. Have a look there. If it's not there, make sure you've installed the iptable package.

Manny88 · 09-21-2003, 08:12 PM

Ok. I don't see ip*, iptunnel, and ipmaddr. No iptable. What package would that be?

adz · 09-21-2003, 08:48 PM

What kernel version are you running?

Manny88 · 09-21-2003, 08:51 PM

uhh... Whatever the Mandrake 9.1 is. Also what type of package would that be? I searched through my package options under rpmdrake and didn't see anything. Although I did finally get my traceroute I didn't see anything to do with extra bash commands ect ect.

adz · 09-21-2003, 10:15 PM

Have a look on google for a package called iptables or something. I'm not sure what the mandy packages are called. To find out your kernel version type uname -r.

Manny88 · 09-21-2003, 10:28 PM

its 2.4.21-0.13MDK

Manny88 · 09-21-2003, 10:42 PM

Ok. I got the iptable package and extracted it, but I can't install because there isn't a config file...

adz · 09-21-2003, 11:31 PM

Before you go into the compilation too far, try to find an rpm so you'll save yourself the trouble of compiling.

If you can't find an rpm then I guess you'll have to compile. So, you're saying that ./configure brought up an error?

Manny88, a silly things for you to do.
Try to check network, such as have you configured your broadcast IP correctly.

I am not sure and this is only a silly things, but its worth to try it, you have nothing to lose.
