(Hmmm...what's the point of "-P" for an HTTP retrieval anyways?) This is on my RELENG_5 desktop: tomcat:bmah% fetch -P -6 http://surfnet.dl.sourceforge.net/sourceforge/xcha= t/xchat-2.6.0.tar.bz2 fetch: http://surfnet.dl.sourceforge.net/sourceforge/xchat/xchat-2.6.0.tar.= bz2: Operation timed out tomcat:bmah% fetch -P -6 http://www.kitchenlab.org/www/bmah/Software/pchar/= pchar-1.5.tar.gz pchar-1.5.tar.gz 100% of 114 kB 14 MBps And then on my RELENG_6 laptop: localhost:bmah% fetch -6 http://surfnet.dl.sourceforge.net/sourceforge/xcha= t/xchat-2.6.0.tar.bz2 xchat-2.6.0.tar.bz2 0% of 778 kB 0 Bps fetch: transfer timed out fetch: xchat-2.6.0.tar.bz2 appears to be truncated: 0/796768 bytes localhost:bmah% fetch -6 http://www.kitchenlab.org/www/bmah/Software/pchar/= pchar-1.5.tar.gz pchar-1.5.tar.gz 100% of 114 kB 544 kBps www.kitchenlab.org is a dual-stack machine. It's on the same subnet as my desktop and one hop away from my laptop. I suspect that there's something about surfnet.dl.sourceforge.net that's kind of funky (note intensely technical term) but I'm clueless as to why we can't transfer from it. From tcpdump, it looks to me like the three-way handshake works but the transfer hangs after a few packets have been transferred. I'm not sure why.
