Date: Mon, 24 Jan 2000 23:45:32 PST Mime-Version: 1.0 Content-Type: text/plain; format=flowed Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hey ppl, I'm having some weird weird issues. I have lets say 2 FreeBSD machines (more in reality) @ home, both have two NICs. One NIC on each for the internal LAN via hub, 100Mbs Mactronix - mx0 & mx1 devices (on the problem machine). And the other NICs for external network, ADSL. From say machine A, I can ping machine B fine sometimes, or for a limited time (Machine B, being the one with the problem, and not A.) I can telnet into machine B from A, I can ping B from A, and vice versa then maybe some odd minutes later, or sometimes after a reboot of Machine B, I can't ping B from A. "host down". If I logon to the console of machine B, and ping A then ping from A -> B starts working again. As if the NIC somehow goes into sleep mode? If I'm telnet'd in, leave it there for a while, it'll eventually drop connection. I'm checked the NICs for any IRQ conflicts, changed PCI buses, changed cable, change hub ports, still samething. Does anyone have any ideas, or how I can start to diagnose this more? I'm out of ideas and don't know where else to turn. On the internal LAN, I'm using RFC1918 based IP's, 192.168.x.x/24. FreeBSD 3.4-RELEASE on Machine B and FreeBSD 3.4-STABLE on machine A. Machine B is just a p5-133 w/48megs RAM but running great. No X installed, minimal install. If anyone has any ideas to this or anything, could you please let me know, I'm going nuts trying to figure this out. I need to get this corrected as I plan on having machine B as my NAT router/Firewall/Bastion host, and eventually (jsut for fun) setting up a DMZ with a third NIC. Please CC to my e-mail address, especially if from freebsd-net@freebsd.org as I'm not on the mailing list yet, and can't afford being on too many mailing lists as I'm already swamped in email.
