Request time out in Ping

[Packya]

Pinging with 64 bytes the server seems to reply quite nicely. But when i ping with 8000 bytes...I am getting quite a few "request timed out"....

What are the implications? Should this be of concern? [sig][/sig]

Each packet has a maximum packet size limit of 32,xxx something. you used to be able to crash a machine remotely by setting the packet size really high. Most operating system have fixed this by now. Search for ping of death in a search engine and you can find more on this...

It's not unusual for a ping with a larger packet size to time out sometimes. Fergettaboutit!

Also, I wouldn't use the performance of Ping to judge the performance of my network...

Have fun!

I use ping to ping my servers which sit accross the other IP segment( anther segment) and pipe it to a file with the command:

ping -l 1000 -n 20000 120.120.120.1 > file

with 20000 ping packet it seem to have average of about 35 to 80 time out which is about 0.17 to 0.4%. I am not sure whether it is normal.

someone please help!

You are sending a large packet so it has to be fragmented. So while transportaion if it delayed because of shared media, It may time out . Try same with increased Timeout Parameter you may have good result
