physically / logically re-Enabling eth0
 

hi there Linux guru,

a newbie here ...



i have experience both on rh 7.2 and slackware 9.0 :

i could make eth0 into dhcp mode .. no problem.
i could also release the ip lease .. all by using hand.

the problem is WHENEVER i switch from 10Mbps hub to 100Mbps
hub THEN BACK TO the 10Mbps hub .. the network card
or eth0 seem to be dead.

no light at all on the hub.

few years back, i know how to "physically" turn on a network
card or eth0 for that matter --> only in Solaris (w/c is hme0)
and this is done via the manual hand command of
"plumb".

is there an equivalent is linux ??

of crse my problem is always solved ... if i reboot the linux
box whether it's redhat 7.x or slackware 9
but i dont want reboot .. wanna learn of crse on how to
"turn" the card on again .

again, linux gurus out there ... thanks in advance...

... sitting ... here... waiting.... :)

I normally just restart the network if anything goes wrong, try:


/etc/init.d/nework restart (at least RH 8-9)

guessing for slackware:

/etc/rc.d/network restart (maybe)

Shoud reboot network settings without shut-down.

also on rh:

eth0 down
eth0 up
