Solaris checksum bug not in Solaris 10?

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? nathan -- --------------------------------------------------------------------- Nathan Bills nathan.bills () arsc edu Arctic Region Supercomputing Center "The optimist claims we live in the best of all possible worlds, and the pessimist fears this is true." -- John Adams, second U.S. President. _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://SecLists.Org
