Are you saying you have control of 195.154.162.172?  That is the system with port 21 open.

You showed...

tcp 0 0 192.168.2.10:60088    195.154.162.172:21

The source port of 192.168.2.10 is 60088 connecting with port 21 on 195.154.162.172.

You could always run "wireshark" or "tcpdump" to examine the traffic between your system
and 195.154.162.172.
