NAME

       sshdump - Provide interfaces to capture from a remote host through SSH using a remote
       capture binary.

       sshdump --extcap-interfaces

       sshdump --extcap-interface=<interface> --extcap-dlts

       sshdump --extcap-interface=<interface> --extcap-config

       sshdump --extcap-interface=<interface> --fifo=<path to file or pipe> --capture
       --remote-host=myremotehost --remote-port=22 --remote-username=user --remote-interface=eth2
       --remote-capture-command='tcpdump -U -i eth0 -w-'

DESCRIPTION

       Sshdump is a extcap tool that allows one to run a remote capture tool in a SSH connection.
       The requirement is that the capture executable must have the capabilities to capture from
       the wanted interface.

       The feature is functionally equivalent to run commands like

       $ ssh remoteuser@remotehost -p 22222 'tcpdump -U -i IFACE -w -' > FILE & $ wireshark FILE

       $ ssh remoteuser@remotehost '/sbin/dumpcap -i IFACE -P -w - -f "not port 22"' > FILE & $
       wireshark FILE

       Supported interfaces:

       1. ssh

OPTIONS

       --help
           Print program arguments.

       --version
           Print program version.

       --extcap-interfaces
           List available interfaces.

       --extcap-interface=<interface>
           Use specified interfaces.

       --extcap-dlts
           List DLTs of specified interface.

       --extcap-config
           List configuration options of specified interface.

       --capture
           Start capturing from specified interface and write raw packet data to the location
           specified by --fifo.

       --fifo=<path to file or pipe>
           Save captured packet to file or send it through pipe.

       --remote-host=<remote host>
           The address of the remote host for capture.

       --remote-port=<remote port>
           The SSH port of the remote host.

       --remote-username=<username>
           The username for ssh authentication.

       --remote-password=<password>
           The password to use (if not ssh-agent and pubkey are used). WARNING: the passwords are
           stored in plaintext and visible to all users on this system. It is recommended to use
           keyfiles with a SSH agent.

       --sshkey=<SSH private key path>
           The path to a private key for authentication.

       --remote-interface=<remote interface>
           The remote network interface to capture from.

       --remote-capture-command=<capture command>
           A custom remote capture command that produces the remote stream that is shown in
           Wireshark.  The command must be able to produce a PCAP stream written to STDOUT. See
           below for more examples.

       --extcap-capture-filter=<capture filter>
           The capture filter

EXAMPLES

       To see program arguments:

           sshdump --help

       To see program version:

           sshdump --version

       To see interfaces:

           sshdump --extcap-interfaces

       Only one interface (ssh) is supported.

         Output:
           interface {value=ssh}{display=SSH remote capture}

       To see interface DLTs:

           sshdump --extcap-interface=ssh --extcap-dlts

         Output:
           dlt {number=147}{name=ssh}{display=Remote capture dependent DLT}

       To see interface configuration options:

           sshdump --extcap-interface=ssh --extcap-config

         Output:

               {tooltip=The number of remote packets to capture. (Default: unlimited)}

       To capture:

           sshdump --extcap-interface=ssh --fifo=/tmp/ssh.pcap --capture --remote-host 192.168.1.10
           --remote-username user --remote-filter "not port 22"

       To use different capture binaries:

           sshdump --extcap-interface=ssh --fifo=/tmp/ssh.pcap --capture --remote-host 192.168.1.10
           --remote-capture-command='dumpcap -i eth0 -P -w -'

           sshdump --extcap-interface=ssh --fifo=/tmp/ssh.pcap --capture --remote-host 192.168.1.10
           --remote-capture-command='sudo tcpdump -i eth0 -U -w -'

       NOTE: To stop capturing CTRL+C/kill/terminate application.
