Hello,
I am looking to find a way to record data usage from a specific device on my network. Ideally the out out would be a text file with the total usage. Is there a way to have iftop run in the background and have it update a file.
Does the -t option to iftop do what you want? You would redirect the output to a log file or pipe it to a script.
If not, is there another utility that people know about the might be able to help me?
Another solution if you're trying to do traffic accounting is something like net-acct. On a students' network, we used to log something like (timestamp, source IP & port, destination IP & port, volume), and then use this to hunt bandwidth hogs.
