Debian sshpass - Non-interactive ssh password authentication
Post date: May 4, 2008, 17:05 Category: Security Views: 1309 Comments: 1
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.
Linux Entering A Safe Mirror When Logging In With Unionfs And Chroot
Post date: June 27, 2007, 19:06 Category: Miscellaneous Views: 793 Comments: 0
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).
Ubuntu Disk ARchive (Backup and Restore) using dar and kdar(dar Frontend)
Post date: January 12, 2007, 12:01 Category: System Views: 1151 Comments: 0
Tutorial quote: Dar is a shell command that makes backup of a directory tree and files. Its features include splitting archives over several files, CDs, ZIPs, or floppies, compression, full or differential backups, strong encryption, proper saving and restoration of hard links and extended attributes, remote backup using pipes and external command (such as ssh), and rearrangement of the “slices” of an existing archive. It can now run commands between slices, encrypt archives, and quickly retrieve individual files from differential and full backups. Dar also has external GUI like kdar for Linux,thanks to the well documented API.
Unix+clones Execute Commands on Multiple Linux or UNIX Servers part II
Post date: December 28, 2005, 04:12 Category: System Views: 1020 Comments: 0
Tutorial quote: I have already covered how to execute commands on multiple Linux or UNIX servers via shell script. The disadvantage of script is commands do not run in parallel on all servers. However, several tools exist to automate this procedure in parallel. With the help of tool called tentakel, you run distributed command execution. It is a program for executing the same command on many hosts in parallel using ssh (it supports other methods too). Main advantage is you can create several sets of servers according requirements. For example webserver group, mail server group, home servers group etc. The command is executed in parallel on all servers in this group (time saving). By default, every result is printed to stdout (screen). The output format can be defined for each group.
