ObjectivesThis screencast continues on with the ldap server we setup in the previous screencast, but this time we will configure another server (client.test.net) to authenticate its users against our LDAP. This is a concept known as centralised user authentication, where by we can store all our users and their credentials on one server. The screencast is basically a walk through of the changes that need to be made to PAM (pluggable authentication modules) which Linux uses to determine how user...
OverviewThis screencast shows a walk through of installing openldap and phpldapadmin. After installation I go through and setup a couple of organizational units to store users and groups which I’ll use in a later screencast when I configure ubuntu to authenticate against against an LDAP server for user logins.This screencast doesn’t really acomplish anything overly exciting but is required before heading into some of the things that LDAP can do, such as centralized user authentication or stori...
OverviewThis screencast starts by showing you how to enable SNMP on a Cisco router (please note the configuration of other Cisco devices such as catalyst switches is slightly different). Then we look at getting all log messages forwarded through to Zenoss so they show up as Zenoss events. I then go back and setup forwarding of the /var/log/syslog to Zenoss on the Linux server we configured in the first Zenoss screencast.(I ran over the youtube limit of 10 minutes with this video and so had to ...
This screencast shows you how to add a user and configure them to receive alerts for a specific class of devices (in our case any Linux server) via email. It also quickly shows performance data which the test server setup in the first Zenoss screencast has collected (after running for two hours).
In this screencast I show you how to download and install the Zenoss server software, how to configure an Ubuntu Linux server to run SNMP and then how to add that SNMP enabled server to Zenoss for monitoring.Hopefully someone with find this helpful to get them up and running quickly with Zenoss. Just as a precautionary note, I would probably advise against using SNMP (and certainly with my config file) if you’re monitoring servers over the internet, but on a secured LAN it should be fine.Below...
This first screencast is going to get you up and running with a very simple puppet manifest that will be used to install emacs and a custom motd banner on a server. Below is the example site.pp manifest I used in the demonstration. node ‘client.test.net’ { package { “emacs22-nox”: ensure => installed } file { “/var/run/motd”: source => “puppet:///files/motd” } }
