Yep, look: truss -t connect -v connect mconnect ... connect(3, 0x00021470, 16) Err#146 ECONNREFUSED name = 127.0.0.1/25 Nice huh. >Casper, you mentioned some changes to truss for 2.6 regarding >more informative tracing. Can you possible elaborate a little further. I'm not sure if truss is changed that much; what has changed is /proc, instead of just one file, it's now exploded into little files & directories (binary files), pretty much like the original /proc design documents said it should have been/. >I personally think Solaris 2.5 is one of the best Unixes out there >from a feature (s/w debugging) standpoint.

With the side by side comparison of Linux/SunOS 4/Solaris 2.5 someone did showed that Solaris 2.5 was generally faster to much faster than SunOS 4.x. (Solaris 2.x is also penalized in the process exec times because it links *all* code, including "hello.c" with -lsocket -lnsl; -lnsl drags in four more libraries so the penalty is stiff) >Also any approx idea of the 2.6 release schedule? I cannot possibly comment on that. >Oh and one other thing, can anyone at Sun explain why 2.5 and 2.5.1 >exist at all for the x86 platform? Why isnt 2.5 just dropped and >provide a patch upgrade from 2.5 to 2.5.1. I suppose we'd reeally want everybody to run the latest release, but since we can't force people to do so, we need to support older releases. But even if Solaris 2.5/x86 was EOLed *now*, we'd still have contractual obligations to make patches and such.
