How-To: encrypted partitions over LVM with LUKS
Even though new distros installers tend to support filesystem encryption out of the box, most of the time, it might be interesting to actually understand how it works, mainly when it happens that your system fails to boot :).
Most literature found on the Internet tend to cover how to set up LVM over a partition encrypted with LUKS, this tutorial takes another approach and will explain how to create LUKS encrypted partitions over LVM. The reason for this.... I wanted to have unencrypted partitions :D.
How-To: Remote syslog logging on Debian and Ubuntu
syslogd is the Linux system logging utility that take care of filling up your files in /var/log when it is asked to.
On a standard system, logging is only done on the local drive. But syslog can be configured to receive logging from a remote client, or to send logging to a remote syslog server.
Some of the use cases could be:
- A machine which filesystem goes read-only
- Log replication
this tutorial will explain how to set up both the server, to receive message from a remote client, and the client to emit messages to a syslogd server.
How-To: Set up a LAN gateway with DHCP, Dynamic DNS and iptables on Debian Etch
Linux is a perfect platform to act as a router/gateway.
In this tutorial, I will explain how to set up a Linux box to operate as a network router. The box will provide the following services:
- DHCP server to provide the ip addresses to the machines in the LAN
- DNS server to resolve domain names
- Gateway with IP tables to give access to the Internet.
- Firewall with IP tables.
The resulting machine will have quite a small footprint: about 600M, and except if your network is intensively used, a low spec computer can be recycled to do the job.
As the machine is going to operate as a router/firewall
How-To: Intel Wireless 4965 AGN with Ad-Hoc network + WEP
The Intel wireless card 4965 AGN does not work properly on ad-hoc networks since hardy and kernel 2.6.24 or around, network-manager can't get it to use the mode ad-hoc and a standard configuration like:
$ sudo iwconfig wlan0 essid myessid mode ad-hoc channel X key s:mykey13charss
$ sudo dhclient wlan0
will fail to get an ip except a long battle at dhclient'ing around.
I managed to get a process to get things working faster.
