no reply from ping
Hello and many thanks,
FC6 Linux pbx.X.X 2.6.18-1.2798.fc6 #1 SMP Mon Oct 16 14:37:32 EDT 2006 i686 i686 i386 GNU/Linux Weird issue I can't seem to solve. I ping google, yahoo, anything outside of our networks and I get no response, the same if someone trys to ping this machine where routing is involved. In other words I can ping this machine from within this network but if routing is involved, nothing. Code:
[root@pbx ~]# ping google.com Quote:
Code:
[root@pbx ~]# traceroute google.com Code:
[root@pbx ~]# ifconfig Quote:
MTIA [edit] I just saw now in the output of that ifconfig up there on interface etho this line with an overrun RX packets:292511 errors:0 dropped:0 overruns:1 frame:0 <- bad? |
You have given a lot of info.
One question, Do you have any proxy servers running? As i've had problems with network apps and proxies. What i can say is that your DNS seems to be working (as it translated google.com to 64.233.167.99). Also if i am correct, your gateway seems to be on a netmask of 0.0.0.0? and you have 2 IP addresses for eth0 (nothing odd there but still could be a problem). I assume the 192.168.0.0 is for the internet and most networking. Have you tried manually setting these addresses and not using 192.168.0.0 try 192.168.0.22 or something above 10. Hope this is helpful |
I've had this same problem when /etc/sysconfig/iptables was set not to accept pings, and iptables is instructed to drop the packet. When that happens you get no response, which sounds like your problem.
To test this theory do a: service iptables stop Then see if you get any different results with your ping. |
Your ip addresses suggest you are on a local lan, so maybe you're behind a router? The router may have it's own firewall which is blocking ping. (My router does have a firewall, and it does block ping in and out of the local lan by default.)

@tomcdyer Thank you for your response.

Any other ideas guys/girls? MTIA |
Does the router firewall accept pings for all IP addresses or just a specific range? If range then perhaps the new IP address is out of that range.
|
@DotHQ Thanks again for your reply
No ranges. This ip address was used until yesterday, when it was given to this machine. The machine that owned the ip address yesterday had no networking hiccups of any kind. |

Here is my interface setup info. Code:
[root@pbx network-scripts]# cat ifcfg-eth0 Code:
[root@pbx network-scripts]# cat ifcfg-eth1 I agree with those that are suspecting firewall, but I have turned off that suspect. I have double checked to make sure the perimeter firewall is not blocking, it absolutely is not. I really am stumped. MTIA |
OK, got it sorted out. It was at the router. We used to have(until a week or so ago) a T1 line which I did not know had statically configured routes for this machine(IP).
Thanks to all for your help and ideas. |
Glad you sorted it out
