Setting up a serial console

Post date: February 19, 2007, 19:02 Category: Miscellaneous Views: 3499 Comments
Tutorial quote: This tutorial will show you how to set up a serial console on a Linux system, and connect to it via a null modem cable. This is quite useful if your Linux server is in a headless configuration (no keyboard or monitor), as it allows you to easily get a console on the system if there are any problems with it (especially network problems, when SSH is not available). In the end, the GRUB menu will appear over the serial link, as will the bootup messages (output when booting the system). I am using Debian Etch on the server and Ubuntu Edgy on my client, although this should work on any Linux distribution.

Custom Monitoring MySQL and SNMP with BixData

Post date: February 3, 2007, 00:02 Category: Software Views: 3202 Comments
Tutorial quote: With BixData you can monitor your servers as well as VMware and Xen. BixData includes pre-built plugins for things like CPU, Memory, Disk, etc. but any good monitoring tool needs to be customizable. BixData includes the basic ability to run scripts and record their exit values, similar to Nagios Plugins. BixData 2.7 adds support for importing data in more complex formats. This allows you to monitor almost anything. I'll go through the steps showing you how to monitor MySQL locally where an agent is installed and then the steps to monitor a device remotely through SNMP. The advantage of BixData is that any data available through a BixAgent works with the standard tools such as the situation room, scoreboards, notifications and the reporting system. All data are stored in standard SQL tables and are easily accessible.

Back Up Linux And Windows Systems With BackupPC

Post date: January 28, 2007, 21:01 Category: System Views: 4479 Comments
Tutorial quote: This tutorial shows how you can back up Linux and Windows systems with BackupPC. BackupPC acts as a server and is installed on a Linux system, and from there it can connect to all Linux and Windows systems in your local network to back them up and restore them without interfering with the user's work on that system. On the clients minimal to no configuration is needed. BackupPC supports full and incremental backups, and it comes with a neat web frontend for the administrator and normal user so that backups and recoveries can be managed through a web browser. It should be noted, however, that BackupPC does file-based backups, not bit-wise backups like Ghost4Linux, for example, so it is not made for disk/partition imaging.
