I have just installed Zone Alarm and within 2 mins it has blocked 50 access attempts. all of these are ping(????)

What exactly is that

Fatman

Ping is a TCP facility to tell whether a host is online or not. Are your inbound pings from the internet, and are they all from the the same host or from many hosts?

ianmiller999

Most of them are different however alot of the IP's begin 82.

ianmiller999

Just noticed that none of them have been classed as a major threat

Fatman

If you're curious about who they are, you can run a Who is? query. Or just switch off reporting and don't worry about it.

I used to get loads of 'attacks' when I used to use peer-to-peer file sharing. It was just clients looking for hosts to peer with.

No, pings aren't normally serious. Unless they're sent in epic quantities. Then it's called a Denial of Service (DoS) attack. In that case, the system is bogged down with simply recording each inbound packet that it can't perform its intended function.

That's very likely NOT happening here.

Thanks

The good old teardrop and ping of death type DoS are a thing of the past. Todays kernels handeling not only ICMP packets but all packets in general have algorithms built to deal with these. Firewalls also have algorithms to cope with these. Poeple don't have enough bandwidth to overcome home wires these days alone. Thats when they turned to the SYN/ACK atacks, but clever tricks with the kernel and IP have seen to that to.

DoS is much better planned these days.....or should I say DDoS or DRDoS or ...... hehehe, loads of untracable ways out there at the moment, and they are getting more inteligent!!!
