It should be possible send and receive ICMP packets using the Ruby socket library but I do not see any good documentation on this.
I do not want to use net-ping, icmp, ping, and all of these other libraries that either fail because of cross-platform issues, require devkit and custom building, which fail during the build process, are neglected and have not been updated for a lengthy time, and/or are just in general buggy.
Does anyone have any good documentation on how to accomplish this? I want to send ICMP echo replies, not TCP or UDP packets.
Reading Daniel Berger’s code on his Net-ping project I was able to see how he did it.
