Post date: December 29, 2006, 20:12 Category: System Views: 3078 Comments
Tutorial quote: Secure Shell is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over unsecure channels. It is intended as a replacement for telnet, rlogin, rsh, and rcp. For SSH2, there is a replacement for FTP: sftp.This might be useful if you are trying to connect everytime to your server remotely.

Mounting Remote Directories With SSHFS On Debian Squeeze

Post date: September 22, 2011, 10:09 Category: Miscellaneous Views: 4202 Comments
Tutorial quote: This tutorial explains how you can mount a directory from a remote server on the local server securely using SSHFS. SSHFS (Secure SHell FileSystem) is a filesystem that serves files/directories securely over SSH, and local users can use them just as if the were local files/directories. On the local computer, the remote share is mounted via FUSE (Filesystem in Userspace). I will use Debian Squeeze for both the local and the remote server.

Working with SUSE Linux Enterprise Server 9

Post date: June 22, 2005, 09:06 Category: System Views: 3509 Comments
Tutorial quote: Working with SUSE Linux Enterprise Server (SLES) requires an understanding of the login process, including local account files, system accounts, and managing identities.

Using a console shell or the graphical environment are two possible methods of working on a SLES machine.

Finding your way around a SLES installation requires an in-depth knowledge of the filesystem layout. Essential filesystem components are documented and explained in this chapter. Basic filesystem permissions are also described.

sshpass - Non-interactive ssh password authentication

Post date: May 4, 2008, 22:05 Category: Security Views: 5752 Comments
Tutorial quote: SSH’s (secure shell) most common authentication mode is called “interactive keyboard password authentication”, so called both because it is typically done via keyboard, and because openssh takes active measures to make sure that the password is, indeed, typed interactively by the keyboard.

Sometimes, however, it is necessary to fool ssh into accepting an interactive password non-interactively. This is where sshpass comes in.

Entering A Safe Mirror When Logging In With Unionfs And Chroot

Post date: June 28, 2007, 00:06 Category: Miscellaneous Views: 2642 Comments
Tutorial quote: When reading a hint on the website of LinuxFromScratch I discovered the special capabilities of unionfs, specially in combination with chroot. Later I read a HowTo on a wikiwebsite of Gentoo, about entering a chrooted home directory when using a special script as shell. Combining these two brings me to using a chrooted environment, which you enter when logging in as a special user. This environment is an exact copy (mirror) of the system you are working on. Because you are in safe copy of the real system, you can do whatever you like, it will never change the system, everything stays inside the cache (the readwrite branch).
