Loosing Ethernet Connectivity

[David Schulz]

Hi,

thats harsh, because before i used a cheaper Mitsubishi, forgot the  
Model, but before Christmas i purchased a Cisco ws-c2960-48tt-l ,  
which i thought was not too bad for what i needed. I just cant  
replace it easily now. Really, is that it? Im gonna have to go with  
the cronjob / shell script option?

So sad,
David
