Hey,
Port State Service 22/tcp open ssh 25/tcp open smtp 37/tcp open time
Are you sure you need this???
80/tcp open http 111/tcp open sunrpc
And this? It's kind of dangerous to have this running. A lot of exploits are floating around which are attacking this service. Unless you _really_ need it. Close it up! Or block it at the firewall at least!!!
119/tcp open nntp
Sure you are using this?
444/tcp open snpp 515/tcp open printer 888/tcp open accessbuilder 901/tcp open samba-swat 4557/tcp open fax 4559/tcp open hylafax 6000/tcp open X11
All of the above I'd probably close down as well. I really don't know why you would those services to be running!!!!
12345/tcp open NetBus 12346/tcp open NetBus 31337/tcp open Elite
Nice. As reported earlier on this list. Unplug your machine from the net. Very possible you were hacked!!!! Check what is running behind 12345 with lsof and netstat¨!!! Thanks Raffy
