Linux Setting up a serial console
Post date: February 19, 2007, 13:02 Category: Miscellaneous Views: 1347 Comments: 0
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.
Linux The Serial Console
Post date: April 14, 2005, 08:04 Category: Hardware Views: 1140 Comments: 0
Tutorial quote: In these modern times, a hardworking admin might be tempted to turn her back on the Old Ways, and indulge in increasingly exotic methods of interfacing with servers: SSH over ethernet, USB, Firewire, wireless, infrared, KVM switches, VNC, VPN... next stop: direct neural implants.

There's one old timer that still has useful place in the admin's tool kit: the serial console. Sure, it's slow and funky. But there are times it can be a real lifesaver. When nothing else works, it's a direct pipeline into your system. It's simple and cheap. You don't need to install drivers or expansion cards, it's just there.

Administration via serial console is common in data centers. Just imagine the nightmare of trying to connect all those rack units to keyboards and displays. The cabling can be extended to a nice comfortable ops center (well, an ops center, anyway). (This Lantronix Console Manager is an example of the type of device used to administer these.)

There are a number of ways to make the physical connection. You can connect an external modem--the kind us old timers fondly refer to as "real" modems--and do remote administration via dialup. It couldn't be any simpler, just dial direct. Or grab a null modem cable, connect to a laptop or a nearby workstation, and you have an instant terminal.

Unix+clones Screen: an introduction and beginner's tutorial
Post date: April 15, 2005, 18:04 Category: Software Views: 812 Comments: 0
Tutorial quote: Most modern Unix-based operating systems (e.g. Linux, MacOS X, and BSD) come with a little console-mode utility called GNU Screen. It's a powerful tool in the hands of the console warrior, a veritable Swiss Army knife of text-mode human-computer interaction.

This utility, despite its considerable usefulness, goes unused by a great many people. Why is this? Few people even know it's there, and those that do rarely understand the problem it solves. In this article, I will explain what screen does for you, and provide a simple set of instructions for accomplishing basic tasks using screen. My audience is those that are skilled with the command line but who have little or no experience with screen itself.
