How will my existing Apache installation be influenced by the installation of ISPConfig?

The ISPConfig Apche webserver is installed in parallel with your existing Apache installation. The ISPConfig apache is only used for the controlpanel. The hosted webpages are served by the Apache that ships with your linux distribution.

This means you do not have to compile special modules into your Apache in order to work with ISPConfig. You can compile Apache and PHP the way you like.

The ISPConfig installer comments out the PHP settings in your httpd.conf. PHP can be later enabled for each web separately in the ISPConfig web interface.

Error messages during installation

During the installation process I get the following error messages though the respective programs are installed on the server:

iptables: command not found
httpd: command not found
useradd: command not found
apachectl: command not found

This means that the programs mentioned are not in the path of your Linux installation. Please type

echo $PATH

on your command line, and make symbolic links to the programs in one of the directories that is in the path. For example, you can create a symbolic link to the program /path/to/apachectl in the directory /usr/bin by going into the directory /usr/bin and typing the following:

What is the difference between standard and expert mode during the ISPConfig installation?

In standard mode the installer assumes standard values for you Linux distribution which may not always be correct (but in most cases).

In expert mode you will be asked about those values which gives you the possibility to change them.

How can I login to a site with Frontpage?

The user name is admin, the password is the one that you entered in the ISPConfig control panel in the form of the respective site.

One of the users on the system has a CatchAll-email address. He receives all emails, even those for users of another site...

One of the users on the system has a CatchAll-email address. He receives all emails, even those intended for users of another site on the same server. The MTA on the server is postfix.

Please check if the domain of the users that receives all emails is the same as the domain $mydomain in /etc/postfix/main.cf. If this is the case, change $mydomain and run

postfix reload

on the shell.

You should never enter a domain that is used for a virtual site on the server as $mydomain in /etc/postfix/main.cf!

I cannot send and/or receive emails.

Please check if Sendmail/Postfix and your POP3 daemon are running by executing

netstat -tap

You will get a list of all services listening on your server.

If they are running re-configure your firewall (iptables or ipchains) so that the ports 25 (Sendmail/Postfix) and 110 (POP3) are not blocked. If this does not help please check that Sendmail/Postfix is really running on port 25 and your POP3 daemon on port 110.

(Hint for standard RedHat installations: If you have webmin installed and are running Sendmail, go to Webmin->Servers->Sendmail->Sendmail Options. Under SMTP Port Options you often find the following entry:

How do I make my MySQL server use TCP connections instead of Unix sockets?

Comment out the option skip-networking in the file my.cnf which typically lies under /etc or /etc/mysql. Then restart your MySQL server:

/etc/rc.d/init.d/mysql restart

or

/etc/init.d/mysql restart

With

netstat -ta

you can check if MySQL is reachable via TCP.

Quota does not work under SuSE 8.2!

On a standard SuSE 8.2 installation the quota module is not loaded into the kernel which is why

quotaon -avug

gives back an error.

Load the quota module manually with

insmod quota_v1

and

insmod quota_v2

To have those modules loaded on every bootup of the system please insert

modprobe quota_v1

and

modprobe quota_v2

in /etc/init.d/boot.local.
