An ping issue on Linux kernel 2.6.25

Dear Sir:

I have met an issue about Netfilter. The version of my Linux kernel is 2.6.25.

Connect to the internet, and then open the command prompt and ping using "ping wwwlclix.pt -t". In the beginning I can get respose but after disconnect and connect the internet never responds again, but if I try to open the site in the web brower it works.

I have checked the nf_conntrack table, it seems that the nf_conntrack item for icmp had not been updated.

Is this a bug? Or is this a especial transaction considering some reason?

Thanks very much!

Regards

If you are talking about packet and byte counters being 0 in reply direction then it might be a bug that was fixed after 2.6.26 kernel. Check commit 718d4ad98e272daebc258e49dc02f52a6a8de9d3.

Hello,

So you have an issue. Maybe it is related to your setup. But you do not tell anything about your setup, how could one tell ? Is netfilter running on the machine which sends the ping or on another machine acting as a routeur ? Is there some NAT or masquerading ? What is the ruleset ? What do you mean by "disconnect and connect" ? Do you have a variable IP address ?

What do you mean by "updated" ? What did you expect, and what do you observe instead ?
