I (Host A – Windows based using plink) am trying to connect to a remote linux server (Host C), through a gateway linux server (Host B), and run this tcpdump on Host C to be piped all the way back to Host A (through Host B I assume), and opened, in real time, with Wireshark on Host A:
Below is what I saw as the command when not using a gateway ("direct remote fetch"). So, how would I make this work going through my gateway host B scenario above?
Host A$ plink.exe -ssh -pw abc123 root@Host C "tcpdump -s0 -U -n -w – -i eth0 not port 22" | "C:\Program Files\Wireshark\Wireshark.exe" -k -i –

:Plain nested commands should work just as well (the
-A
option for SSH agent forwarding is useful in this case):
