From: AG on 27 May 2010 05:40 Hi List Every now and again the lights on my broadband modem start flashing which indicates package transmission/ receiving. When I have deliberately started an application to access the web (e.g. web browser, email client, etc.) that's fine. I do get a little concerned however when the lights flash and I cannot find an app that is accessing/ receiving info from the web. How would I go about finding out what application is connecting to the web and/ or what is connecting to my machine to cause the modem light activity? I've tried ps -A and ps -aux but this shows up a lot of info which makes it difficult to see any particular activity that may be responsible. Is there a bash command (or a GUI app) that will identify what the connection is and who/ what initiated it, etc.? I'm using an up-to-date testing installation. Thanks for any help.

Bit of a learning curve, but appears to do the job. Thanks for the suggestions. Best AG -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?
