Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.. It's 100% free, no registration required.

I want to see a list of all outgoing HTTP requests from my desktop. I think it should be possible to monitor HTTPS hostnames as well for local clients using Server Name Indication (SNI).

OS X has a nice GUI utility called Little Snitch, which is a per-app HTTP monitor and firewall rule front-end.

I would settle for a nice terminal utility. tcpdump is overkill as I just want to see where the traffic is going in real-time and not the transmitted data. Ideally, I would like to see what process made the request as well, but just seeing what dials home would be a nice start.

You can use lsof and watch to do this, like so:

$ watch -n1 lsof -i TCP:80,443

Example output

dropbox    3280 saml   23u  IPv4 56015285      0t0  TCP greeneggs.qmetricstech.local:56003->snt-re3-6c.sjc.dropbox.com:http (ESTABLISHED)
