-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This morning I put 7.1 on a Via box with RealTek 8139C+/8169/8169S/8110S Ethernet card (from sysinstall). I'm new to FreeBSD, but I've been playing with this box to learn a little about the BSD side. The network seems not to work unless the interface (re0) is in promiscuous mode. I don't understand this. arp -a looks reasonable, and it doesn't change when promisc is turned off. ping works to localhost and to re0, but if I start a ping to outside the machine, nothing happens until I enable promisc by starting tcpdump or by issuing a command to ifconfig. Then the echoes start. And disabling stops them again. I don't think it's hardware because this box ran Debian Linux for several months with no problems -- unless maybe the Debian driver kept it in promisc all the time; I didn't look... rc.conf: > # -- sysinstall generated deltas -- # Sun Mar 29 09:52:35 2009 > # Created: Sun Mar 29 09:52:35 2009 > # Enable network daemons for user convenience. > # Please make all changes to this file, not to /etc/defaults/rc.conf. > # This file now contains just the overrides from /etc/defaults/rc.conf. > hostname="otto.slsware.lan" > ifconfig_re0="inet 192.168.3.177 netmask 255.255.255.0" > defaultrouter="192.168.3.1" > font8x14="NO" > font8x16="swiss-8x16" > font8x8="swiss-8x8" > ### linux_enable="YES" > ### nfs_client_enable="YES" > ### saver="daemon" > webmin_enable="YES" > # -- sysinstall generated deltas -- # Sun Mar 29 12:45:49 2009 > gateway_enable="NO" > router_enable="YES" > ftpd_enable="YES" > inetd_enable="YES" > named_enable="YES" > ntpd_enable="YES" > postfix_enable="YES" > routed_enable="YES" > rsyncd_enable="YES" > sshd_enable="YES" ifconfig -a: > re0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 > options=389b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC> > ether 00:30:18:a0:29:dc > inet 192.168.3.177 netmask 0xffffff00 broadcast 192.168.3.255 > media: Ethernet autoselect (100baseTX <full-duplex>) > status: active > re1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 > options=389b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC> > ether 00:30:18:a0:29:dd > media: Ethernet autoselect (10baseT/UTP <half-duplex>) > status: no carrier > plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> metric 0 mtu 1500 > lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 > inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4 > inet6 ::1 prefixlen 128 > inet 127.0.0.1 netmask 0xff000000 This is with promisc on.
