Subject:   fetch -b and TCP/IP (=bug in Solaris 7 TCP stack?)

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.
