(DOS) what is it?????

**hoggy952** · 19 February, 2012, 22:08

ms-dos is a disk operating system,that means it is simply a system for operating the disks.
dos is an entirely text based system,all it provides for the user is a prompt :"C:>" or "A:>" where the user can type in commands,the system is entirely case insensitive.
so either "ForMAT C:" or "format c:" would erase your hard disk.

with DOS comes power,you can very easily mess up your system if you use powerfull command in the wrong way.
the commands you should be carefull are, "Format" "Recover" and "Del".all of these perform usefull functions when used correctly.

DOS in this case is your modem/router reporting a Denial Of Service attack.

More than likely a false positive if you are using any P2P or sharing in some cases.

No, that's something, or someone attempting to connect to your computer on various UDP ports. However since it appears to be attempting to connect to your internal IP address then it is likely to be some software that you have installed that is 'advertising' such as utorrernt.

The IP originates in Italy although bounces around quite a bit before that. Your firewall is doing what it is supposed to do.

This goes on everywhere on a daily basis and as said it can be a false positive based on what you have said.

Use this and test your set up to see that your security regards open ports is up to date and working correctly https://www.grc.com/x/ne.dll?bh0bkyd2 just click the link and follow the prompts, it is quite safe to do so.

While Dos is Disk Operating System and is what hoggy952 says. In this case i think it is not that type of Dos
[DOS] in a modem or router usually refers to a Denial Of Service attack.
This means that somebody is trying to cause problems on your network. Either deliberately or Speculatively.
It could also be the result of a file sharing program such as torrents, Kazar and the like.
If the IP address you give is based in italy then the computer that appears to be attacking you is based in Italy, although if it is an attack the person who's computer is attacking you may not be the source of the attack. Their computer may have been compromised and might be being used by someone else to attack you.

If i was you i would check and make sure that you wasn't using any file sharing program when the apparent attack occurred.
I would also make sure that you have no ports open to the outside world on your router/modem using a site like shields up on the gibson research website, see here.You should be looking to have a stealth result if you test your network with shields up.

I am not the greatest expert in this area as i am only mildly paranoid, i am sure there are better experts on Digital Kaos.
