Hi, welcome to LQ!

You could easily set-up iptables to log any connection attempt,
but you may find that this is quite verbose and more info than
you're after ...


Cheers,
Tink

Paranoid are we?

How are you connected?

You have several options available. Tinkster suggested iptables. If you would provide a little more information about the LAN configuration then we could narrow in on our suggestions.

I am going through a router to dsl. Paranoid maybe but I used to use zonealarm and they had 2, one would tell me the ip trying to look at me and the other who it was. Normally since I went to linux I did not worry but I have windows unit on the router also and I have had some strange things going on. I checked with zonealarm and they don't have those programs any more. A friend told me that doing too much with linux may create a problem because the better people use linux.

This is a 64 byte unit with suse 11.1 on it. I have a direct connect to the router. Unfortunately I lent out the disk to someone and they appear to have lost it. I am new at using linux, loved dox and hated windows but have had to use it until I was laid off.

I hope this give the info you are looking for will try to answer any other questions

Sorry, but being hit by port scans behind a DSL router,
specially when you have more than one machine attached,
doesn't make any sense at all. How would the router know
which machine to pass any inbound traffic on to? In a worst
case scenario you should be seeing traffic responses from
boxes where you initiated a connection by SOME means, and
the router passes the established connection on to your
machine that sent the SYN out. Or does your router actually
service a subnet of public IPs? That would be most unusual
for a DSL device.



Cheers,
Tink
