plenty RAM and HD

Problem:

I am currently on a modem connection - the built in 56K v90 - and about every 3rd time I call up, or at least every 2nd day, the modem connect window shows me that a lot of sending is going on, right after connect. Sometimes it lasts for several minutes - and sometimes so CPU-demanding, that I cannot even access my mail app (Eudora) or have priority to open a Finder window.

I have Virus checked, and seached for software to monitor the port transmission, to maybe get an idea of what is going on - but no viruses and no software.

ANYBODY have an idea - either a possible explaination or the name of a piece of software with gentle instructions about how to interpret results?

You could try a program called Snort. Find it on versiontracker.

Or use tcpdump as root in the terminal.


Sorry, I can't be much help with interpreting the info.

sudo tcpdump -i ppp0 -n -w output_file will dump the traffic to a file. If you want, I will look at the file and see if I can determine what is going on.

Forgot to add, I use several tools for analysis of captured traffic but for this purpose I would start with Ethereal

I'll see if I can figure out how to do it.

thank you for the information and your time.
