That is normal PING behaviour, you may even get it on Linux
ocasionaly... (pinging a Win machine :)
The explanation is simple: Before sending the ping to the destination
machine, the system has to resolve ARP and this may take some time.
Only after that the ping will be sent. So if the network is slow
(gprs) or the desination machine is slow (win) i may happen.
Since hist network (GPRS) is PPP-based, are you sure that the
explanation applies to his situation? When using PPP, ARP should not be
needed/used and every outgoing packet should be sent to the PPP peer, so
no resolve timeout should occur...
You got me... almost. Someone has to do ARP, probably the router at the
other end, which should not be so slow. But since GPRS is very slow (2s
eventual delay is normal) this can be it. And if there is also DNS, it
may be even slower.
Anyway, I have seen this a lot so I consider it normal for the first
ping. For the second, it may vary with some configs but I am not sure.
