Re: [fpc-pascal] raw socket example
Here's an example: https://github.com/Laksen/fp-ethernet/blob/master/linuxraw.pas You need to change ifindex obviously, and I can't remember how that was found. But it should be relatively easy.

There's no more IP address (as shown in the example). The whole protocol stack needs to be handled manually. I don't think there's any publish FPC raw-socket example. The easiest way is to find C raw-socket example and port it to pascal. thanks, Dmitry ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

I do not know which version you are using, but if it is a recent one, the rename of the openssl unit is the only change. ;) I've been using the one from here: http://svn.freepascal.org/svn/fpcprojects/lnet/tags/release_0_6_5 Btw: the openssl unit form lnet is exactly the same as the openssl unit in fpc. Maybe the trunk of lnet is updated, but otherwise there is actually a large difference in the two units. A whole lot of RSA/PEM and other certificate functions are not included in the lnet one. I made a quick diff of the two files (lnet vs. fpc opensl) and it is more than 100K bytes large... :) Regards, Torsten. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
