Re: unknown services

Hi,

/etc/services should give a little bit of description here.

Email, does your machine run as a mail server, accepting or delivering
mail for you (not via netscape or other POP/SMTP client) ?

> 53/tcp     open        domain 

DNS. Are you running a (caching) name server on your box ? (Bind)

> 631/tcp    open       unknown 

Don't recognise this.

> 1024/tcp   open      kdm 

Don't know, but I guess you have KDE installed, and this is for some
service of KDE to talk to another part. If you don't use KDE then disable.

> 1025/tcp   open      listen 

Don't recognise this. Most services "listen" on a port, so its not very
descriptive.

> 6000/tcp   open      X11    

Do you run X, or serve X apps from this box ? If no, then you can disable.

You can probably disable all except the KDM and X11 without causing any
performance problems on your box, and simply booting to run level 3 will
mean you can fix the other couple by editing /etc/services and
/etc/inetd.conf (remember backup these files first, otherwise you can
really kill your box)
