Remote capture using linux

unknown

Hi all.... Does anyone already implemented a remote capture for linux using the sniffer mode available on Ruckus AP's? Using wireshark on windows I have the "Remote Interfaces" feature... However, I need to perform a capture using linux command line (ex. tcpdump, tshark, or similar). I already tried the rpcap for linux but this is not working.
I'm using the standalone AP R730 without controller.

Hi Oscar,

All Ruckus APs supports remote streaming capture feature but running tcpdump is not available.
You can access standard CLI called "rkscli" over SSH, which is on top of linux, but shell access to any Ruckus AP is not available for consumers. It is limited to Ruckus engineering and Ruckus support.

Hi @Syamantak Omer,

Thanks for your answer. I have SSH access, can I use "rkscli" on my device to enable the capture?
Today I'm using the following CLI commands to enable a stop the capture.
- set capture wlan100 stream (start)
- set capture wlan100 idle (stop)

With Windows I'm able to receive the packets, however, using linux I'm not able to receive the packets.

Thanks.

Hi Oscar,

"rkscli" is the name of the CLI prompt, it is not a command.

To start the captures over the radio, please refer below commands.

For 5 G OTA

- set capture wifi1 stream (start)
- set capture wifi1 idle (stop)

For 2.4 G OTA

- set capture wifi0 stream (start)
- set capture wifi0 idle (stop)

Hi Syamantak,

I know how to enable the captures 🙂

I just need to undestand how to receive the captures on linux. Do you have a solution for me?

Hi Oscar,

This probably might help you:

1. From the linux machine, SSH into the AP.
2. Run a tcpdump from the CLI for the interface you want.
3. Save the logs in a pcap format.
4. Export the file to the local system via a FTP server.

Note: TCPDUMP command has to be run from the AP shell mode, you need to contact our support team to get this done.
