2. How do I access and open an account on XS4ALL ?

To Connect to our system: 
Our dial in modem numbers are:
020-6222175     2400-28800 bps, 100 lines. 
020-6265060     19200 bps for ZyXEL modems, 20 lines.

Dial 020-6222175 (modem speeds up to 28800 bps max.). 
Dial 020-6265060 (ZyXEL modems, speeds to 19200 bps). 
From another Internet site by the UNIX command...
‘telnet xs4all.nl’ or  ‘telnet 193.78.33.42’ 
This can be done from the ‘free’ public system ‘De Digitale Stad’ (020-6225222). 

When you are connected, login as ‘new’ (all lowercase characters) and enter 
the requested information. Choose an account name carefully. It will be 
combined with our system name ‘xs4all.nl’ to make the e-mail address on 
which you will be known on the Internet. For example choosing ‘john’ will 
name you ‘john@xs4all.nl’. You cannot change this afterwards. Choose a 
password that you will not forget. The password will be case-sensitive, so 
remember capital characters.

A good password, for example is... %KK%p)p   Using UPPER and lower case letters and some of the charactors like... #%^&*()_+=-) makes it much harder
for someone to crack your password (a rare chance, but possible).

You can always make changes to passwords by the UNIX command... passwd
It looks like this ...  
xs1:/home/m/machelp $ passwd
Changing NIS password for machelp on obelix.
Old password:
New password:
Retype new password:
NIS entry changed on obelix
xs1:/home/m/machelp $

You won't see yourself type in the password change, so think and remember 
your new password before you make the changes to it. 

After this ‘new’ procedure, you can wait for the invoice which will be sent 
by regular mail or write down our (Post)bank number and client name
and make the transfer yourself. We will activate your account as soon
as we receive a confirmation of your payment. After activation you
can enter the system.
