(This is what I thought in the begging the real question is on my 3rd posting)

I am running Woody 3 stable with apache,ssl, php4, openSSH installed using apt.

When I do nmap scann on my server SOMETIMES I get the following open ports. What are there for? and how can I remove them?

1470/tcp open uaiact
1518/tcp open vpvd

Thanks but...

It's lsof -- not Isof (with small L, not with big i).

lsof not Isof

(maybe this should go to another thread...)

Excuse my spelling mistake, it did work this time.

But unfortunately it does not solve my problem.

For some reason which I do not understand if I do repeated port scans with nmap SOMETIMES I get open ports on DIFFERENT addresses each time(e.g 1550/tcp as you can see below), which I hadn't realized when I did the first posting.

So lsof does not help me as these ports are changing all the time and last just for an instance...
The other weird thing is that if I do netstat repeatedly I never get those open ports (as you can see below)...

What is going on? Could this be a security problem? Or what could cause it?

Any help would be appreciated..
Alexis
