Created attachment 94695 [details, diff] arpping.c for iputils-021109-r3 with select replacing signals. this is a replacement for arpping.c rather than a patch because the changes were pretty extensive. the changes, however, boil down to replacing signals with select to implement timeouts. this should be more reliable and more resistant to c library changes, operating system and the like. one gotcha. the manual says that arpping -c 1 quits after sending a single packet. i think it's a little strange, but that is what the man page says.
