OpenSSH is the implementation of the SSH protocol. OpenSSH is recommended for remote login, making backups, remote file transfer via scp or sftp, and much more. SSH is perfect to keep confidentiality and integrity for data exchanged between two networks and systems. However, the main advantage is server authentication, through the use of public key cryptography. From time to time there are rumors about OpenSSH zero day exploit. Here are a few things you need to tweak in order to improve OpenSSH server security.

Raiden's Realm :: Linux Mail Storage Formats: Mbox vs MailDir |
|
Written by bibe

marted́, 21 luglio 2009 |
The subject of standard Unix and Linux mail file formats came up as part of a recent article I was writing and I decided that it was something that needed to be addressed to avoid confusion when talking about it in the future.
The two primary formats for mail storage in Linux and Unix are Mbox and MailDir. There are several other formats out there as well, including MMDF (a close cousin to Mbox), MH (similar to MailDir, but used more in IMAP mail senarios), and BABYL. Other than Mbox and MailDir, most other formats are either deprecated, obsolete, or in very limited use. Hence most end users won't encounter said formats and thus don't need to worry about them. Therefore, we'll only concentrate today on the primary two formats.

Written by bibe

domenica, 24 febbraio 2008 |
This guide explains how you can enable a remote desktop on an Ubuntu desktop so that you can access and control it remotely. This makes sense for example if you have customers that are not very tech-savvy. If they have a problem, you can log in to their desktops without the need to drive to their location. I will also show how to access the remote Ubuntu desktop from a Windows XP client and an Ubuntu client.

Linux.com :: Running Debian GNU/Linux from an encrypted USB drive |

Written by bibe

|
domenica, 24 febbraio 2008 |
You're probably familiar with the live CD concept -- a fully functional operating system on a CD that can be run on any computer that boots from its optical drive, without affecting the one(s) already installed. In a similar vein, you can set up Linux to run from a USB hard drive drive on any computer that can boot from USB. The live system offers automatic detection and configuration of the display adapter and screen, storage devices, and other peripherals. A bootable USB drive can run a mainstream Linux distribution such as Debian GNU/Linux, and can be secured, personalised, upgraded, and otherwise modified to suit your needs.

The /proc directory is a strange beast. It doesn't really exist, yet you can explore it. Its zero-length files are neither binary nor text, yet you can examine and display them. This special directory holds all the details about your Linux system, including its kernel, processes, and configuration parameters. By studying the /proc directory, you can learn how Linux commands work, and you can even do some administrative tasks.
