Hi, I had some problems getting my ports to work, and a few minutes ago, I found the problem. My FreeBSDīs port 80 is transparently sent through an Inktomi Proxy server on a Solaris 7. If I want to fetch something, I need to add the -b flag to fetch something. Now I would like to find out whether the bug mentioned below is in Solaris 7 or in the Inktomi Cache server. So maybe some of you TCP stack hackers have a way of testing this against a Solaris box? From the fetch man page: Some TCP implementations (other than FreeBSD) fail to correctly implement cases where the SYN and/or FIN control flags are specified in packets which also contain data. The `-t' flag works around the latter deficien- cy and the `-b' flag works around the former. Since these are errors of the server's TCP stack, the best we can do is provide these workarounds. Given a correct server, an optimal HTTP transfer without -t and -b in- volves a minimum of two round trips (for small replies), one less than other implementations. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /\/\orten $eeberg, Systems Consultant @ Merkantildata - Enterprise Solutions #echo 'System Administrators suck :)' > /dev/console To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
