(only with pf enabled) X-BeenThere: freebsd-net@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Networking and TCP/IP with FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 02 Jan 2006 17:51:42 -0000 Hello, On nearly all of my recent 6-STABLE servers, I got complaints from the users that transferring "larger" amount of data fails. For example on FTP and HTTP downloading about 500k-1M works, but after that the connection breaks. Similarly, when looking for large (a few thousand) mail folders via IMAP, the client yells that there is a problem. I got reports from Linux and Windows users. The solution is to turn RFC1323 support off on any side. What could be broken? FreeBSD? The intermediate network? Linux, Windows? Between two FreeBSD boxes, everything is OK. I use pf on all machines, if that counts... ... yes, that counts. Without pf it works OK, but when I load a simple pass only ruleset, it breaks. The strange thing is that FreeBSD-FreeBSD works with pf loaded, but FreeBSD with Windows or Linux doesn't. Any ideas? -- Attila Nagy e-mail: Attila.Nagy@fsn.hu Adopt a directory on our free software phone: +3630 306 6758 server! http://www.fsn.hu/?f=brick
