You can't do that remotely. It has to be done on the linux box. Packet sniffing means that somebody with elevated privilege on a (linux) box set a NIC into promiscuous mode. You have to physically get on the linux box and stop whatever is going on there. Then remove privilege for all the users on the box & change root password. This will "block" it.

So, you have problems. Elevated privilege on a linux box and other security issues. As well as to why packet sniffing was set up.

I would simply speak with the admin on the box to find out what is going on. The admin may be running something for security. e.g., snort
