I have a suse 10.1 , my internet fiber connection goes down after about 10 minutes if I don't use the computer. I disabled the power management settings from Desktop configuration - > Display , but still.. about ten minutes after I stop using the computer the connection dsl0 (which is my internet connection ) goes down: /varlog/messages says : ifdown: dsl0. I assume this has to do with the fact that my monitor also goes into standby after about ten minutes.. but I don;t understand why it does that ..because.. as I said I disabled the settings for display power management. Do I have to disable anything else ? I can bring dsl0 back up if I do ifup dsl0 as root , but I obviously don;t want to do that every time the conneection goes down, and also not everyone will be root when that happens on this computer. Can anyone help me ?

You need to give more information. Is this a laptop? What kind/model? How are you connected through a router? Directly to a modem? What desktop? KDE/Gnome??

No, it's not a laptop. It's a normal system : amd 2200+ , 521 mb RAM , 128 MB video. I don't kknow if there's a router , I guess not , because I have no device .. no modem no anything. My fiber optic internet connection is composed of these two connections :
dsl0 Link encap:Point-to-Point Protocol
inet addr:79.119.216.155 P-t-P:10.0.0.1 Mask:255.255.255.255

The ip for eth1 is always the same : 10.10.12.100. I guess it's a MAN .... I don't understand exactly how it works using these two connections eth1 and dsl0.. but a friend tells me in windows it's the same: two connections and one of them is always 10.10.12.100. Why does the link keep going down ?

Ok this is pure guess work. I suppose that in windows you had to load a driver for the optical interface card and you ISP, I assume was added to your computer since the optical goes straight into it. Also I suppose by your description that as long as you use the connection all is will it is just when the you leave it idle for more then 10 min it shuts down. Again just guessing the Window driver probably does some periodic update that keeps the connection live. So how about having a cron process that pings some outside address periodically, say ever 5 min. This may keep the connection alive.

The cron ping worked. Thanks.
