The install is done via USB/ethernet adaptor. Because of the change to recvspace lately (now 65536) the USB/ethernet adaptor (or the switch, not sure) is overrun and resulting installation speed drops to unacceptible 10KB/s. It is not a problem for me, because I can manipulate per sysctl recvspace in my package. But it may become a problem for people which want to install FreeBSD 4.5 over USB/ethernet with the normal sysinstall (for example laptop users). AFAIK there is no knob if you boot from floppy. -- Thomas Zenker c/o Lennartz electronic GmbH Bismarckstrasse 136, D-72072 Tuebingen, Germany Phone: +49-(0)7071-93550 Email: thz@lennartz-electronic.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
