While working on a windows 2003 server which has a plesk 8.4 control panel, I got the following error:

Unable to add ip xx.xx.xx.xx with mask 255.255.255.0 to interface PublicNetwork, WMI error code 42
Execute file name: C:\Program Files\SWsoft\Plesk\admin\bin\ifmng.exe

This means that there is an IP conflict, to get this fixed – you have to contact your dedicated server provider and ask them to remove the IP address or to provide a new IP address.

Assuming that you have a plesk dedicated server and a domain hosted on it, and you need allow_url_fopen to be “ON” (enabled). Just follow the below steps to get this done.

Create a vhost.conf file under /home/httpd/vhost/domain.com/conf and add the following code.

<Directory /home/httpd/vhost/domain.com/httpdocs/>
php_admin_value allow_url_fopen On
</Directory>

Once done, you will have reconfigure plesk and the command to do so is:

/usr/local/psa/admin/sbin/websrvmng –reconfigure-vhost –vhost-name=domain.com

Now, restart apache on the server.

That’s it!

The chkconfig command can be used to activate and deactivate services. You use “chkconfig –list” to query a service in “/etc/rc.d”, that service’s settings for each runlevel are displayed. For example, the command “chkconfig –list httpd” returns the following output:

httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off

Viewing chkconfig Entries:

root@server# chkconfig –list | grep on

Modifying a chkconfig entry is almost as easy as listing the existing configuration. The form is:

chkconfig [--level <levels>] <name> <on|off|reset>

Runlevels (–level)

0. System halt
1. Single-user mode
2. Multiuser, without NFS
3. Complete multiuser mode
4. User defined
5. X11 (XDM login)
6. Reboot
