Hi,

I ping my office Linux (Fedora Core 3) router public IP from my home windows machine:

ping <linux_public_ip> -l 10000 -t

and i get a reply from my router with that big buffer size.

Well packets getting fragmented to 1500 (MTU) as i can see in "iptraf" running on linux router.

If i do same on google.com obviously i get timed out.

TO achieve the same I digg alot and find this tcp parameter

/proc/sys/net/ipv4/ipfrag_time = 30

I make it 0 (secs)

and ping again and voila i get timed out and only get reply if i pass buffer size 1470...thats good.

But are there any side effects of this?

Thanks!
