Re: 2 networkcards in 1 system
I suppose you use both NICs on a same network - you use common network segment or use common switch/hub. This is an old issue - try to change the segment or use vlans on the switch :) Regards, Ivailo Tanusheff Deputy Head of IT Department ProCredit Bank (Bulgaria) AD Pieter Donche Sent by: owner-freebsd-questi...@freebsd.org 13.01.2009 13:04 Please respond to Pieter Donche To "mail.list freebsd-questions" cc Subject 2 networkcards in 1 system I installed FreeBSD-amd64 on a system which has 2 networkcards and configured 1 networkcard with its IP parameters.

How to remedy? You can add the following two lines to /etc/sysctl.conf: net.inet.tcp.blackhole=2 net.inet.udp.blackhole=1 ...and reboot or type, as root, sysctl -w net.inet.tcp.blackhole=2 sysctl -w net.inet.udp.blackhole=1 > > Or do I need to 'deconfigure' em1? How can I do that? Edit /etc/rc.conf manually, either using ee or vi and comment out the lines you don't want active. You have connected the two network cards to the same switch, yes? don't do that. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "Failure is the opportunity to begin again more intelligently." --Henry Ford ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
Re: 2 networkcards in 1 system
Hi, >and selected em1 and gave it its IP parameters > (I used the same hostname macos.cmi.ua.ac.be, in the DNS servers here > macos.cmi.ua.ac.be is assigned to two IP addresses) First I doubt that this will work. You can assign several names to a single IP address in DNS, but you cannot assign several IP to the same name. > (After rebooting, em1 appears in the boot messages with the correct > Mac- and IP address.. ) > > But I get many messages: > Jan 13 11:05:25 macos kernel: arp: 143.129.XX.YY is on em0 but got reply > from 00:1b:21:UU:VV:WW on em1 > Jan 13 11:54.25 macos kernel: arp: 143.129.XX.YY is on em0 but got reply > from 03:ba:14:UU:VV:WW on em1 Let me guess, both NIC are connected to the same network? If so you cannot predict what interface will reply first, so you can send a packet through one interface and get a reply from the other interface. In standard operation, you don't want to have your two NICs connected to the same LAN with and IP in the same subnet. > Or do I need to 'deconfigure' em1? How can I do that?
