You can see it in the 'top' list. Starting tkpppoe it's listed with PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND 23664 wobo 9 0 2712 2712 1868 S 0,0 1,0 0:00 wish After running some time I have it like this: PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND 22982 wobo 15 0 40416 39M 1924 S 1,1 16,3 4:53 wish You can even watch it consuming memory when you look at 'top' running for a minute. As I'm not too good in scripting and/or coding I just close it now and then and open it again. wobo -- "... and anyway, an html can't carry a virus."
