Question

Hi All, How can I see which users are connected by pptp vpn ?

Answer 1

Hello,

Toy could try following commands to filter connections on PPTP port 1723:

• netstat -n | grep 1723

and

• cat /proc/net/nf_conntrack | grep 1723

They will not provide username details, but will give you connection details an information based on source/destination IPs/hostnames in packet headers.

You can also enter the command:

• ifconfig

or more specific

• ifconfig | grep P-t-P

It will provide a list of active PPTP links, as each active connection creates an interface. If there is no connection, there is no interface. The same applies for routes to specific. The command 

• route -n 

will only show destination IPs of clients, which are connected.

Best regards,
