Remote ssh connection to my Network

asked 2020-06-11 11:28:20 +0000

Folks,

New to Wireshark, I'm not looking for an exact answer, just an understanding of what is possible.

Main machine an Ubuntu laptop, I have promiscuous mode enabled. I also have a RaspberryPi running Raspian, which is an ARM version of Debian.

The R-Pi is running an Apache server which I use to transfer files to a friend abroad. I manage the R-Pi using ssh and also connect to my friend's remote computer using ssh. When connected to the remote machine I use wget back to my network to transfer the files.

If I have a filter with the local address of my R-Pi should wireshark be able to monitor the network traffic to my P-Pi?

How are your laptop and the RPi connected? Do they use a wired or wireless network?

The ubuntu laptop is connected by wifi to the router and the R-Pi is connected by ethernet cable into the router.

The apache server running on the Pi is really for personal use between myself and friends, only https is available to the internet and that with password login. Appreciate could use a smaller web server but it works and am happy with it.

With your setup the Ubuntu laptop will not be able to see the traffic between the RPi and the internet as it won't be transmitted over WiFi an the router is a switch so will only send traffic to the port that requires it.

You may be able to capture traffic on the router itself, or configure the router to mirror or span the traffic on the RPi port to another port that you connect your Ubuntu laptop to, or you can capture directly on the RPi, e.g. with TCPDump.
