System: FreeBSD 3.2 on Pentium platform.
It was working fine until today. Today I installed MySQL and Webmin and
configured NFS. All worked fine except I can't ping localhost (127.0.0.1).
/etc/hosts has the line says 127.0.0.1 localhost. Where should I look at?
Thanks,
Joseph

I am assuming you have pseudo-device loop configured in your kernel
already.
Hope that works AND helps. :)

network_interfaces="XXXX lo0"
ifconfig_lo0="inet 127.0.0.1"
XXXX is your NIC card.
On 3.X it should be the same, but I can't tell you exactly because I
still had a chance to play with 3.X yet. I don't think rc.conf is used
in 3.x anymore but is there for backward compatibility.

Within a ksh script, I would like to first determine whether or not
a remote
host is alive before I attempt other network access to it, (file reads
or writes).
The ping command seems to be the logical solution, but if I have to wait
for
the ping command to fail due to network time-out to indicate that the
remote
host is not available I've gained nothing over just letting my other
network
access commands time-out.
Is there a way to execute ping wrapped in a timer - such as in a
subprocess
that gets killed by it's parent if it doesn't end within a practical
time interval?
It seems to me that that should work, but what I'm really looking for is
someone who would share code that has already been written.
Much appreciated.
3. D-link DE220 can PING his own IP, but can't PING others'
5. Can I prevent pinging from others and still ping others?
6. KERMIT: How to tell which serial line to use?
7. Can ping linux itself, but can't ping others
9. Strange network problems - pings to host are fine, pings from host fail
10. It's not bad canned meat...
11. Can't ping hosts outside of local network
12. Can't ping the host name or host IP address from host.
