Message-ID: <20010507162005.C55671@luke.immure.com> Reply-To: Bob Willcox Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I am working on a FreeBSD device driver for my Co's GSN adapter and need to be able to set my TCP/IP window size to 512KB (or perhaps more). I have tried doing this with sysctl: root@sebulba:p0 /root> sysctl -w net.inet.tcp.recvspace=524288 net.inet.tcp.recvspace: 131072 -> 524288 root@sebulba:p0 /root> sysctl -w net.inet.tcp.sendspace=524288 net.inet.tcp.sendspace: 131072 -> 524288 and although the sysctl happily takes the specification, when I attempt an ftp command I get: root@sebulba:p0 /root> ftp 192.168.1.2 ftp: socket: No buffer space available This is on a FreeBSD 4.0-stable system: FreeBSD sebulba.vieo.com 4.0-STABLE FreeBSD 4.0-STABLE #202: Mon May 7 15:09:46 CDT 2001 bob@sebulba.vieo.com:/usr/src/sys/compile/GPXTEST i386 Anybody have any ideas what I need to do to get this to work?
