Hi

I have a standard sftp server running that comes with Redhat AS 3, I want to find out

1.at a given time how many users are connected to the server
2.if possible what are they doing (uploading or downloading)

Regards

Hi asankacgl,

I belive that "netstat" will give you the information. just check the number of IP address connected to the port of your ftp server.

Thanks Angel but is there a simple way of checking like w command, because this will be used by audit personal not by a linux literate

Ok so try this in a bash script:

Code:

#! /bin/bash
SFTP_port=21

echo "The number of connection to the SFTP server is: " $( netstat -a |grep tcp |grep :${SFTP_port} |wc -l)

This should do the trick

Good advice, angel115. I only would add the -n option to the netstat command. This will force the numeric representation of adresses and ports, otherwise the default ports will have their name ("22" will be "ssh").
