network interface down on standby mode (general linux question)

[jaredb0t]

Hi, I don't know how kosher general linux questions but here goes...

I've got a red hat 7.2 box networked with my windows machine, but when the linux box goes in to standby (power saving) mode (monitor off/hard drive off), I lose all network functionality, ie seq will no longer work, and I can't access the internet, nor will file sharing work. The only way I seem to be able to bring the network back up is to restart. So basically what I'd like to know is:

A) Is there a way I can shutdown and restart the network interface without rebooting the machine?

or

B) While running KDE I can't seem to figure out how to stop the computer from going into standby mode.. (well i just realized i haven't tried the bios yet).. I have all the options set to NOT go into powersaving mode in the KDE config.. no screen saver... no power saving etc..

I would really prefer (A) because I don't use my linux machine much other than to use seq and would like it to be in power saving mode when i'm not using it.

Thanks

Generally, you will find better answers on linux forums... thats kindof the idea of a topic forum.

try "ifdown eth0" then "ifup eth0" (or do a "man ifconfig" for more information.

also, if you are using mdk/rh you can use "service network restart" or "/etc/rc.d/init.d/network restart"

I found the only way to kill the standby mode was to go into the bios and disable all of the power saving options.

There might be a way to do it in KDE but I haven't found it yet.

as root execute the command: ntsysv

scroll down and make sure a service named 'apmd' doesn't have an asterisk (*) beside it. If it does, turn it off and restart.

Also, you should disable any system suspend options in bios.

You may be having the same problem I had with Linux going into standby. I did same, I went everywhere and turned off screensavers and powersavers but no cigar until someone told me about the TERMINAL window has it's own standby mode.

Try this: open terminal window and type:

xset s 0 0
xset s noblank
xset s off
xset -dpms

showeq

Once i did that showeq quit shutting down on me...
