Tips / Hints


Networking
By default, the server boots using DHCP, so if that isn't going to work inyour setup, you will have to modify it yourself. You can use thecommand
netconfig
 
to change the IP and subnet to your network's standard. Pleaseremember, that after modifying any Network Configuration, it isnecessary to restart the networking service. You can do so withthis command
service networkrestart
 

Synching the Time
After first boot you will want to issue the command:
ntpdate -u0.pool.ntp.org
 
several times to synchronize your time. NTP is set to run onstartup to keep your clock synchronized, but it will not updateproperly if your hardware clock is way off.

Changing the root password
You will also want to change the default root password, as its veryinsecure if you were to leave the server internet accessible.

FTP is not enabled
FTP is disabled on the server for security reasons. To add ormodify files on the server from Windows, it is recommended that youuse a program such as WinSCP or Putty

Nightly Updates
Yum is setto run automatically every night in order to keep your CentOSinstall updated with the latest security patches. This may causedifferent issues when packages are updated, and you can no longeraccess the resource until the proper services are rebooted (ex:MySQL). If this becomes an issue, then you can disable the nightlyYum update by issueing these commands.
service yum stop
chkconfig yum off
 

Alternate Keyboards
By default, CactiEZ is set to use the qwerty keyboardlayout. This ofcourse can easily be changed by installing an extrapackage. Just run these 2 simple commands (your Cacti server mustbe able to access the internet) and you will be able to change yourkeyboard layout through a text GUI
yum installsystem-config-keyboard
system-config-keyboard
 

Changing the Timezone
You can change the timezone to your local timezone in 2 ways, youcan either use webmin to modify the timezone, or by installing asimple text GUI to allow you to do it.
yum installsystem-config-date
system-config-date
