This sends a batch of lines out port 514 to the remote logger once a minute, logging all open connections.
Code: Select all
write_crontab.sh '*' '*' '*' '*' '*' 'cat /proc/net/ip_conntrack | logger'
Setup Wallwatcher on the Windows PC for a "IP tables" type router. Change the router interface names on that same setup page to src for Lan and dst for Wan (instead of br0 and eth0). Enter 514 for port # and enter the routers IP also. Close Wallwatcher and restart it after a minute. Enjoy.
(p.s. I helped develop part of Wallwatcher )
