Hi,
running iftop command sometimes I can see lines like this:
Quote:
mydomain.org:microsoft-ds
=> rrcs-24-199-42-186.west.biz.rr.com:privatechat
0B 0B 0B


what the hell is microsoft-ds?
my nmap says that this are the opened port.

That's port 445, Windows uses it for SMB (filesharing). Maybe you're using samba or something? Otherwise you should get that checked out ;)

samba is not installed on my linode.
what should I check out?

I'm quite worried about this.

You are sending no data - this is probably someone trying to connect and your server is ignoring it.

I like this hypothesis.
