-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 I am attempting to use the ICMP protocol that is "off-the-shelf" in Boost.Asio, but am unable to get any use of it working. Following the code listed here: http://www.boost.org/doc/libs/1_36_0/doc/html/boost_asio/overview/networking... I immediately run into problems. The DAYTIME protocol is defined to operate on TCP or UDP port 13. ICMP should be used for control messages, not data transmission. Trying to connect to a server supported DAYTIME with ICMP does not work using the code at the previously mentioned site, this error is returned: Service not found Which makes sense because this service is not defined for this protocol. My question is, what is the intended purpose of the current implementation of this protocol? If to use ICMP to tranfer data by using the payload, why? If to construct messages useful for writing a traceroute or ping utility, how would I do this? Has anyone used this library? Online there is a desire to use boost.Asio and ICMP to write ping using boost, but they all reach these same questions. I am appreciative of any help on this topic. - -Chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEAREKAAYFAkpK05UACgkQS3i4IU3+Scsw2QCbBAQpHwqzTqIvn3hVunI6bnK9 Z6AAn0EfsRAwPbon8jJYVotEe6awn7Xy =/gWa -----END PGP SIGNATURE-----
