(I sent this to the list three times in the past two days; it apparently
never arrived, and it did not bounce.)
I rebooted, and did a few netstat's and an iftop while the workstation
was "quiet". I pasted output from 2 netstat runs into a text file.
I paused the iftop display many times to grab line pairs of interest,
and pasted those into the text file that has the netstat runs.
The text file is attached.
Most of the entries in the iftop display involve comcast, my internet
service provider. Quite a few unexpected addresses also show up in
iftop. A few questions come to mind...
A few years ago, I saw in the system journal numerous log-in attempts by
outsiders from all over the world, and opened a thread about that. Now
such attempts are blocked by the firewall. If an outsider tries to
communicate with my workstation, and the firewall blocks the attempt,
will the attempt show up in the network activity panel of ksysguard?
Will that attempt show up in the iftop display?
Bill.
