http://www.canyouseeme.org/ - an online port checking tool

very basic but should serve your needs.

as for the dynamic IP, there are ways to handle that. one step at a time.

YOUR THE BEST MAN!!!!
port is opend
i was asking aorund a bit and people told me ill have to buy a domain if i want a dynamic ip web server
is ti true????????
im instaling debbian tomoeow morning!!!!!
im not shore im up to this
is it hard to instal it
do i have to format the disc with a fat or ntfs?????

Its not hard to install, it takes time.

about domain, you can access your page via ip or dns name. If you have dynamic ip, name is preferable. Search dyndns in google.
I think it works that way: if ip changes your system tells dyndns that "hi, I own yourdomain.jj and I have new ip" and www.yourdomain.jj works again with new ip.

ok i get it
but you have to pay the domain
so i was thinking is thee any other way to host the server with a dynamic ip adrass??????
or i have to buy the domain????

If you would check out dyndns (http://www.dyndns.com/services/dns/dyndns/) you would see that they offer a free dynamic ip address domain.

ok
ql
so i first instal and evrything then whan the server is up i ask for a domain????
tnx

is there any way to instal linux while beeing on windows xp??????

Only if they are on different machines. you can't run two os's at once.

(Before anyone else says , i know you can with emulators, but lets not confuse the matter to much)

Anyway i was going to say,
You said you had problems booting from cd on that old 400mhz machine. If you still have the original cd drive in it, it may not be recognizing the media. Some old drives have problems with cd-r and cd-rw, or even just the brand of media (some are better than others).
Also the thing with setting the boot order and it not staying might be the bios backup battery dying. One way of checking this is to see if the bios times stays up to date.

bios battery is ok
primary boot device is set to cd-rom
OS at the moment is win. xp
and in windows the cd is readeble it also runs autorun
i see no problems but ill try to change the drive with a newer one
ill post the resolts
tnx
