tcpdump to SD card


Recommended Posts


I want to write the output of tcpdump to my external SD card.

The external SD card is on filesystem /dev/sdcard/sd1 and mounted to /sd (this is what Infusion Resources says).

So as command for tcpdump I used

tcpdump -w /sd/tcpdump.pcap

but the output is not written to that SD card but to rootsfs (which has a very limited space of 3,3MB).

So how can I manage tcpdump to write to the external SD card?

Thank you.
