hi all
Below is the output of ping to our billing server from on one of
another server, when one look into "icmp_seq" sometime there is gap
between two packets for example in icmp_seq=25 <---> icmp_seq=28 and
icmp_seq=21 <---> icmp_seq=23.
I just wants to know these gaps are normal or something to worried about?
regards
Askar

Theese gaps means that the packet is "time out", if you use Win32
you'll see "Request Time Out" at icmp_seq 26,27 and 22. Is this
something to worry about ?? Yes ofcourse, many gaps means many request
time out ( the packet didn't reach the destionation in a manner or
time). You need to check the network.

Hi Askar,
These gaps indicate PING DROPS. If you stop the pinging, the last line before the command prompt will show you the statistics. You will see what the success %age was and how many packets were dropped. Do a traceroute and see at what node in your network the packets get dropped or experience a great delay.
I hope this helps.
Thank you,
Deepak
