Greetings BC community long time no see,
Recently I've taken interest into various aspects of networking, and have been working on increasing wireless security for my current wireless router. One of the things I've noticed is an option to view the access logs, I've noticed various incoming logs that I think are legitimate because they tend to be vary narrow port ranges, and from mostly the same IPs.

I have2 questions:
(please note this is a linksys router)

1. How can I set up a way to store and view incoming/outgoing logs over the period of several days (instead of when only I open the window?).

2. What's a reliable way to see what services are accessing my router to confirm they are indeed legitimate, without having to scan my ports from another machine?

Thanks

Hi ussr, my router keeps a log for a period of x amount of days, not to sure if you can save it. As for Q2: open up a comand prompt and type in nestat -a this will show all the open,waiting and closed ports. http://www.faqs.org/docs/linux_network/x-0...ce.netstat.html

I've used WallWatcher for maintaining logs - but it requires that your router support the syslog feature.
