ok - newbie admin question...
I want to test out a cool command line command...
ifconfig eth0 down
wow! I can't connect to the internet...cool.
ok...
ifconfig eth0 up
no joy...
try
# ifup eth0
instead
Q: what command can I use to determine why I no longer have an internet
conection? netstat and ifconfig just give me a lovely bunch of summary
info. What do I need to look at/do to:
1. verify that I am down
2. get the internet active again.
(NO GUI PROGRAMS - command line answers only please! - although that's
appearantly the only way to manage disk volumes & volume groups (whoah -
later discussion!) )
# ifdown eth0
# (ip link show eth0 | fgrep -q UP) && echo "eth0 up" || echo "eth0 down"
eth0 down
# ifup eth0
# (ip link show eth0 | fgrep -q UP) && echo "eth0 up" || echo "eth0 down"
eth0 up
