PPP Over SSH - a simple vpn solution for unix

PPP over SSH is a quick and dirty vpn solution. You can run a PPP connection over an SSH connection to make for an easy, encrypted vpn. Sure, there are lots of existing, prepackaged vpn solutions out there, but how difficult are they to setup? What do you need to install on *both* points of the vpn connection? Why is the sky blue? What do I need to know? Before I get into the details, I'm first going to explain the situation I'm using ppp over ssh in. The gist of it is as follows: My laptop is on an insecure, wireless, untrusted network.

What do I need to do? There are many steps here, make sure you do all of them :) You need root Before you can actually run ppp(8), you must have root on both the client and gateway machines. Create an ssh key First, you're going to need a passphraseless ssh key so we can login to your vpn gateway without a password. Ssh-keygen -N "" -t rsa -f ~/.ssh/ppp.key. Custom boot screens.

CentOS 5 and the XFS kernel module

If your going to use XFS filesystem you should also install the XFS programs that go with it. Metadata Performance Exploration Part 2: XFS, JFS, ReiserFS, ext. More performance: We add five file systems to our previous benchmark results to creating a "uber" article on metadata file system performance.

Metadata Performance Exploration Part 2: XFS, JFS, ReiserFS, ext

We follow the "good" benchmarking guidelines presented in a previous article and examine the good, the bad and the interesting. Last week we tested four Linux file systems — ext3, ext4, nilfs2, and btrfs — for metadata performance using a benchmark called fdtree. The point of the benchmarks was not really to comparison the performance of the file systems per say, although comparisons are inevitable. Rather, the benchmarks were performed as part of an exploration into the metadata performance of Linux file systems. We’re using the same benchmark from the last article and applying it to additional Linux file systems – xfs, jfs, reiserfs, ext2, and resier4. Quick Review of Benchmark.

What is the CentOSPlus repository? The CentOSPlus repository contains packages that are upgrades to the packages in the CentOS base + CentOS updates repositories. These packages are not part of the upstream distribution and extend CentOS's functionality at the expense of upstream compatibility. Enabling this repository makes CentOS different from upstream.

Networking HP PPA DeskJet Printers using SAMBA.: Emulating a Pos

Emulating a PostScript printer on a Windows Host. If you do not have commercial PostScript emulation software for Windows that will work with your HP PPA DeskJet (the author is unaware of any such software that supports PPA printers), you can use Ghostscript together with HP's native Windows drivers. 4.1 Installing Ghostscript as the emulation software. From the Ghostscript home page download and install (in this order) the Windows packages of Ghostscript (PostScript Emulation Software). 4.2 Adding the fictitious Postscript printer.

In the following, I assume your printer is a HP DeskJet 722C, and is installed with its native Windows Drivers as a printer called "HP DeskJet 720C Series". The following instructions are tested on Windows 98, and may differ on other Windows variants. MakeVM: Virtul machine and virtual disk management and conversio. BOO - Home. CentOS 5.3 Samba Standalone Server With tdbsam Backend. Version 1.0 Author: Falko Timme <ft [at] falkotimme [dot] com> Last edited 04/20/2009 This tutorial explains the installation of a Samba fileserver on CentOS 5.3 and how to configure it to share files over the SMB protocol as well as how to add users.

CentOS 5.3 Samba Standalone Server With tdbsam Backend

Samba is configured as a standalone server, not as a domain controller. In the resulting setup, every user has his own home directory accessible via the SMB protocol and all users have a shared directory with read-/write access. I do not issue any guarantee that this will work for you! 1 Preliminary Note. High Scalability - High Scalability. Linux Configure rssh Chroot Jail To Lock Users To Their Home Dir. Rssh support chrooting option.

Linux Configure rssh Chroot Jail To Lock Users To Their Home Dir

If you want to chroot users, use chrootpath option. It is used to set the directory where the root of the chroot jail will be located. This is a security feature. Online Hierarchical Storage Manager. Yubico.
