Problem with FreeBSD on Ethernet Cc: suresh_nalluri@il.us.swissbank.com Reply-To: armando_ferreira@il.us.swissbank.com Sender: owner-questions@FreeBSD.ORG Precedence: bulk Hi, I have got two questions: 1- Does anybody know of a (good) book on freeBSD sys admin ? 2 - I am experiencing a problem setting up a local Ethernet. One of the hosts (tuna) cannot ping any other host, nor can it be pinged by the others. The only ping commands that work from that host are % ping localhost % ping tuna Could it be that I need an entry in /etc/sysconfig for ed0 ? I only have the following entries: network_interfaces="lo0" ifconfig_lo0="inet localhost" Any help would be much appreciated. Thanks, Armando. P.S. Below are some of the system files and the output of some TCP/IP related commands. dmesg | grep ed0 ================ ed0 at 0x300-0x31f irq 5 maddr 0xd0000 msize 8192 on isa ed0: address 00:00:c0:a8:82:2c, type WD8003EP (8 bit) ifconfig -a =========== ed0: flags=8863 mtu 1500 inet 194.72.241.1 netmask 0xffffff00 broadcast 194.72.241.255 ether 00:00:c0:a8:82:2c lp0: flags=810 mtu 1500 lo0: flags=8009 mtu 16384 inet 127.0.0.1 netmask 0xff000000 sl0: flags=c010 mtu 552 tun0: flags=10 mtu 1500 hosts ===== # hosts,v 1.5 1995/04/09 09:54:39 rgrimes Exp # # Host Database # This file should contain the addresses and aliases # for local hosts that share this file. # In the presence of the domain name service or NIS, this file may # not be consulted at all; see /etc/host.conf for the resolution order. # # 194.72.241.1 tuna tuna.dolcom.co.uk 127.0.0.1 localhost 194.72.241.2 porpoise 194.72.241.3 salmon # # Imaginary network. #10.0.0.2 myname.my.domain myname #10.0.0.3 myfriend.my.domain myfriend # # According to RFC 1597, you can use the following IP networks for # private nets which will never be connected to the Internet: # # 10.0.0.0 - 10.255.255.255 # 172.16.0.0 - 172.31.255.255 # 192.168.0.0 - 192.168.255.255 # # In case you want to be able to connect to the Internet, you need # real official assigned numbers.
