I have Kerio Personal Firewall installed and I am using a DSL broadband service which is left turned on 24/7.

Occasionally I receive this message ..

Incoming Connection Alert!

Time: 04/March 2003 08:34:01
Remote: 61.129.81.139 - ICMP [8] Echo Request

Details: Someone on address 61.129.81.139 wants to send ICMP packet to your machine

Details about application: tcpip kernel driver

What is this btw? Does it mean that there is someone who's running probably a port scanner .. or some kind of scanner to detect who's online and looking for victims with certain vulnerabilities?

Appreciate if someone could help me in this .. ;)

Thanks for the info pal .. but the question that I don't understand is what is Kerio Personal Firewall trying to tell me? That I am being scanned or is that just merely a normal notice of something I haven't understood??

Anyone please? :blink:

It could have been just some ping attempt for various reasons. If Kerio blocked it then I wouldnt be too worried unless it happens constantly.
I'm on PPPoE and I get a tonne of IP's trying to access certain ports. Some are due to infected PC's, some are from P2P programs, and so on. As far as the P2P probes goe, it doesn't happen all the time but only when I get assigned certain IP's when re-connect to the internet. It's pretty obvious in this case that someone that had my IP before me had a P2P Program running. Also happens with Gaming servers.

I used to get echo requests a helluva lot when I had Agnitum, and these would actually slow my entire PC down, I dont think it was the same problem as Krom as I have a static IP.

It is someone scanning your ports. Just deny it and make sure you set it to remember that rule. You shouldnt be bothered with that one agian.

Word of advise if I may. If you get a request from your firewall saying so and so form this ip wants to connect, just deny it. You can always undo it later if it presents a problem. Thats the whole point of a firewall. Dont defeat it purpose.

FYI - port scanning is done via icmp and ping requests are done via udp. just some information from Your Friendly Neighborhood [PseudoKiller]

Ahhhh .. thanks for all the information. I have guessed the same as well. Will do exactly like what was advised, set a rule to deny all such nonsense.

That was exactly the same scenario as what you explained Krom .. I even had scans from visualtracking.symantec.com for what I don't know ???? :happy:

Anyway .. thanks to all of you once again ! Adiosz ...

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there https://tinyurl.com/ycpxl
