Max targets?

[lbrictson]

Is there a max amount of addresses this can ping? I tried using the multi_ping method and giving it 10 retries with 10 seconds for a list of 488 targets, but i'm always getting between 210 and 220 without any response data.

Any ideas? Love this tool otherwise!

Sorry for the delayed response. I'm glad you like multiping.

To be honest, I haven't had a chance to test it with such large numbers of addresses. It "should" work. Are those 488 targets on your local network, or out there on the Internet? It is possible that you are running into some rate limiting issues in your network or service provider. ICMP packets in such large quantities may be considered suspicious.

This issue is caused by the limited receive buffer size. The receive buffer on the socket varies according to the platform.

For local targets, the replies come back faster than they can be read from the socket, the socket buffer overflows, and the replies are lost.

I'll submit a patch shortly to use a larger receive buffer, but perhaps in the long run the receive buffer should be set according to the number of pinged targets.

Fixed by PR #5. Thank you mpghf for the contribution!
