It also may be that you have to run tcpdump with sudo. The data has been encrypted and is unreadable. Examine the Follow TCP Stream window of your SSH session. Right-click one of the SSHv2 lines in the Packet list section of Wireshark, and in the drop-down list, select the Follow TCP Stream option. Enter ssh in the filter field and click Apply. It can be understood that, in most cases, SSH traffic from unknown IP addresses to our internal network can signal that the network has been compromised.

Alternatively, one can provide the password to plink using the -pw option.Īgain, it may be that you have to provide the full path to tcpdump and/or wireshark. Apply an SSH filter on the Wireshark capture data. Filtering Wireshark requests and internal SSH traffic, in addition to that coming from external IP addresses, will help identify suspicious situations.

On Windows I have to omit the Wireshark option -k (immediately start capture) and manually start it from the Wireshark UI once SSH keyboard authentication is done. plink -ssh 'tcpdump -s 0 -w - 'port 8080'' | wireshark -i.

Make sure you filter as much as possible on the remote side using tcpdump’s filters. Please note! Such a remote capture session can be pretty heavy on the network depending on the application. There over 242000 fields in 3000 protocols that let you drill down to the exact traffic you want to see. You may also need to run tcpdump with sudo which means you need to change the command to: ssh remote-host 'sudo /usr/sbin/tcpdump -s0 -w - 'port 8080'' | wireshark -k -i - Wireshark’s most powerful feature is it vast array of filters. The output is sent over SSH to the local host’s stdout where Wireshark is waiting on stdin for input. This will run tcpdump on host remote-host and capture full packages (-s0) on port 8080. Make sure tcpdump is on the path on your remote host or change the line to include the path a la: ssh remote-host '/usr/sbin/tcpdump -s0 -w - 'port 8080'' | wireshark -k -i - ssh remote-host 'tcpdump -s0 -w - 'port 8080'' wireshark -k -i.

There are a few things that may make the line above not work in your case. Wireshark (englisch wire Draht, Kabel und shark Hai) ist eine freie Software zur Analyse und grafischen Aufbereitung von Datenprotokollen, die 2006 als Fork des Programms Ethereal (englisch himmlisch, ätherisch, Anspielung auf Ethernet) entstanden ist.

Right-click one of the SSHv2 lines in the Packet list section of Wireshark, and in the drop-down list, select the Follow > TCP Stream. The output is sent over SSH to the local host’s “stdout” where Wireshark is waiting on “stdin” for input. Apply an SSH filter on the Wireshark capture data. This will run tcpdump on host “remote-host” and capture full packages (-s0) on port 8080. Linux ssh remote-host 'tcpdump -s0 -w - 'port 8080'' | wireshark -k -i. Run Wireshark on your desktop (Linux or Windows) and capture on the remote server. You want to use tcpdump in combination with Wireshark but on the server there is no X environment or no Wireshark installed?
