The problem occurs when transfering files >100MB from the .1 machine to any other. I typically FTP the files out, and I've even tried using samba to get the files onto the other machines. What happens is this: The filetransfer would go nicely, and usually about 30MB into the transfer, the connection would hang. If I try to ping from the .1 box, to the box which the connection had hung, (eg. my .2 or .3 boxes), the ping packets don't get through either. If I do a netstat, I see this: tcp 0 17472 epoch.49170 janus.1037 ESTABLISHED The send queue seems to be full. Now if I wait a while, the stalled FTP/SAMBA transfers sometimes resumes and continues, but most of the time, the FTP/SAMBA transfers time out and I have to stop the tranfer and try again. Both boxes aren't loaded so I don't think it's that. Here's the output of my ifconfig for reference. ed2: flags=8843 mtu 1492 inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255 ether 00:4f:49:05:78:b7 (Note: I'm also using an MTU of 1492 on the connecting boxes due to PPPoE mtu requirements) If anyone has any suggestions on how I can diagnose or even better solve this problem please respond :) Thanks, - Will To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
