next in thread | raw e-mail | index | archive | help
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.
