>What do you mean by "drops"? What are the symptoms? What version of >FreeBSD? Please describe what you observe. Version: FreeBSD 2.2.8. Using a DEC203 (Etherworks3) card. (le0 device). Running on a VESA bus 486 with 32M of ram and scsi disks. The network card is ISA. I configured FreeBSD to have 2 NICs. One to the Internet and one to my private (non-registered ip) with ip forwarding turned off. I also ensure that only TCP/IP was running on the Windows Machines.(i.e. no windows networking). The TCP/IP communications stops working at about 5 minutes every time after the FreeBSD machine is booted and rebooted. If I try to ftp or ping the FreeBSD box from WindowsNT or Window98 ping fails (times out) and ftp fails. From the FreeBSD side if I start pinging the Windows machine and let it continue right after I reboot, ping is okay at first but within 5 minutes the pinging will fail and a message will say something to the effect that "There is no buffer space available" everytime it tries to ping. If I start pinging after a period after reboot when I know the TCP/IP is down ping will tell me that there is a timeout. I am pretty sure the problem is on FreeBSD for the following reasons, if I try WindowsNT or Windows95, I have the problem. Using the same network card with Linux as the server rather that FreeBSD, I have no problem. If I swap the DEC 203 with another DEC 203 on FreeBSD, I still get the problem. But now I have swapped out the DEC and replaced it with a SMC adapter (ed0) and I have no problems. This doesn't solve the problem. It just avoids it. I wish I know enough about FreeBSD to poke around an figure out what is going on. When the TCP/IP droped I did netstat -r to check if the problem was not a routing problem, but netstat -r told me everything was okay. ie. My defaultroute and the gateway to my LAN was listed in the table. I also tried disabling routing and gateway on FreeBSD to isolate the problem. And also I made sure I did not have default route on Windows setup which is other than FreeBSD. -----Original Message----- From: Greg Lehey <grog@lemis.com> To: Edward Ing <inge@home.com>; freebsd-questions@FreeBSD.ORG <freebsd-questions@FreeBSD.ORG> Date: Sunday, February 28, 1999 5:44 PM Subject: Re: TCP/IP on LAN drops after a few minutes. >On Monday, 15 March 1999 at 9:17:18 -0500, Edward Ing wrote: >> I have a ethernet lan network with a FreeBSD machine and a dual boot >> window98/windowsNT workstation machine.
