Hi nmap-dev, When I build nmap 4.60 on Solaris 10 using gcc version 3.4.6 and run a udp scan against a linux target host, I get 'UDP: bad checksum.' errors on the target and nmap reports all the ports as 'open|filtered'. However, in config.h, when I change this: #define STUPID_SOLARIS_CHECKSUM_BUG 1 to this: #undef STUPID_SOLARIS_CHECKSUM_BUG and rebuild the software, nmap runs correctly, reporting that the ports are closed, and I don't see the bad checksum errors anymore on the linux target. Maybe that Solaris checksum bug is no longer there in Solaris 10?
Thanks for the report. I think I see the problem. The configure.ac has: *-solaris2.0* | *-solaris2.1* | *-solaris2.2* | *-solaris2.3* | *-solaris2.4* | *-solaris2.5.1 ) AC_DEFINE(STUPID_SOLARIS_CHECKSUM_BUG) AC_DEFINE(SOLARIS) ;; *-solaris*) AC_DEFINE(SOLARIS) ;; So the idea is to only enable that (poorly named) define for Solaris 2.0 - 2.5.1. But now that we're up to Solaris 10, that "*-solaris2.1*" string is catching again. It looks like this was already fixed in nsock (by Marek, I think), so I have copied the relevant lines from nsock/src/configure.ac and regenerated configure. If you get a chance, would you test the latest SVN version to ensure that it resolves the problem? Also, I'm assuming that you're running Solaris 10 x86.
