I recall when Bryan Cantrill came to one of the local hotels here to announce Solaris 9, I remember him saying that Solaris truss was now an app that called DTrace functions. If people feel the need for trpt-like utility, would it be an idea to write it using DTrace calls? Could it be a GSoC project? It would be kind of neat for a co-op student or someone to get their feet wet with systems programming.
I typically use DTrace when snooping around looking for that proverbial needle in a haystack. And TCPDEBUG seems to be one of those things that DTrace was designed to replace. It would be a good project to have a still in school upcoming developer to work on. -- Cheers, Cy Schubert <cy.schub...@cschubert.com> FreeBSD UNIX: <c...@freebsd.org> Web: https://FreeBSD.org NTP: <c...@nwtime.org> Web: https://nwtime.org e^(i*pi)+1=0
