hi,
you may have problem like ip conflict. Be sure that there is not two machines having the same ip address. When you do a ping,
probably your mac address is learned by the gateway again. Try to add static entry to the gateway for your IP address.
This is what I have faced with in my networks.

best regards.

You don't give very much information. You wrote "This is not the firs box there I had this problem." By box I assume you mean you've had multiple computers attached to this same ethernet cable and had the same problem. If so, that pretty well removes your computer as the problem.

My guess is that the router/switch you're working with has a problem. I have a (cheap, junky) D-Link wireless router at home that will hang if it gets too warm.

It may not exactly be a solution, but you just could use

Code: Select all

ping -i 120 192.168.0.254 >> /dev/null &

or something the like for now. You can add it to /etc/conf.d/local.start so your machine starts to ping on boot.

To diagnose the problem you should whip out ethereal or some other utility and look for a while what happens there... but its most likely just a junky router, like DaveArb said.

Yes, I have a ethernet network, with Windows and linux installed computers, and a linux box with NAT. I had some cases then pc with windows worked fine, but after instaling linux appears this problem. And now I am realy worry about this.
