Create a Linux user sandbox with chroot and unionfs

Up
vote
Down

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). read more...

Tutorial: SFTP chroot user jail on CentOS

Up
vote
Down

This tutorial shows how to set up a safe chroot for your users. It offers chroot only and will deny all SSH access. It should only take about thirty minutes from start to finish including package download times if you don't already have them.

This method is safer because it doesn't allow the users access to any commands such as a compiler or the perl interpreter.
You will not need to install any extensive libraries or copy hundreds of files for functional use.

The user will be 'jailed' to any directory you choose which will mean that they will see "/home/username/" as just "/" disabling them from seeing your entire server or others users files while still using SECURE FTP. read more...

This tutorial shows how to install MySecureShell on a Debian Etch system. MySecureShell is an SFTP server that is based on OpenSSH and can be configured in many ways, e.g. it has support for chrooting users into their homedirs or for limiting upload-/download bandwidths. MySecureShell makes SFTP available for users that do not have shell access so that these users do not have to use the insecure FTP protocol anymore. read more...

Recover root password with chroot

Recover lost root passwords simply with a Linux live CD...
Utilizing a Linux LiveCD, it's simple to "rescue" a given Linux box that has had it's root password changed or forgotten. Of course, this also creates a security risk in business-critical machines. If an employee were to use this on a business server to gain root access, the business would be in some form of trouble (provided the IT Department doesn't know what they're doing).

Restrict users to SCP and SFTP with Chrooted rssh on RHEL

Up

Down

FTP is insecure protocol, but file-transfer is required all time. You can use OpenSSH Server to transfer file using SCP and SFTP (secure ftp) without setting up an FTP server. However, this feature also grants ssh shell access to a user.

In this article series we will help you provide secure restricted file-transfer services to your users without resorting to FTP. It also covers chroot jail setup instructions to lock down users to their own home directories (allow users to transfer files but not browse the entire Linux / UNIX file system of the server) as well as per user configurations. read more...

Follow these step-by-step instructions on how to build 32-bit chrooted environments under 64-bit Ubuntu, and...
...At this point you should have a 32 bit environment setup with synaptic setup. When you run synaptic32 from your main environment it will chroot execute it and all installations will be made to your 32 bit environment. If you want to be able to easily launch 32 bit chroot apps from your 64 bit environment symlink the app name to /usr/local/bin/do_dchroot.

Security: Tutorial: How to chroot Apache

Up
vote
Down

How to set Apache up in a chroot environment -- and why you might want to.
Installing Apache in a chroot jail does not make Apache itself any more secure. Rather, it serves to restrict the access of Apache and its child processes to a small subset of the filesystem. The advantage in chrooting a process is not in preventing a breakin, but rather in containing a potential threat.

Before deciding whether you need to chroot your Web server you should consider the advantages and disadvantages of such a setup.

Get your favorite apps back that are missing from your shiny new 64-bit Linux system...
One way - they say - is to install the ia32-libs, but I wanted to be all clean about it and use the arguably harder ‘chroot' method. This way, one can achiev a modular, easily upgradeble system. Both 64- and 32- bit apps and separated from each other, and all users can - compeletly transparently - call the 32-bit apps from within their 64-bit text consoles and DEs.

Apache 2 chroot: Red Hat

Up
vote
Down

A chroot on Red Hat / CentOS / Fedora Linux operating changes the apparent disk root directory for the Apache process and its children. Once this is done attacker or other php / perl / python scripts cannot access or name files outside that directory. This is called a "chroot jail" for Apache. You should never ever run a web server without jail. There should be privilege separation between web server and rest of the system.

In this exclusive series, you will learn more about:

* Securing an Apache 2 web server under Red Hat Enterprise Linux / CentOS Linux using mod_chroot
* Virtual hosting configuration under chrooted jail.
* Troubleshooting Chrooted Apache jail problem. read more...

How to secure Lighttpd with chroot in Ubuntu

Up
vote
Down

Security, speed, compliance, and flexibility--all of these describe LightTPD which is rapidly redefining efficiency of a webserver; as it is designed and optimized for high performance environments.

A chroot on Linux or Unix OS is an operation that changes the root directory. It affects only the current process and its children. If your default Document Root is /home/lighttpd normal user can access files in /etc, /sbin or /bin directory. This allows an attacker to install programs / backdoor via your web server in /tmp. Almost all-cracking web based attacks/attempts requires a shell access - /bin/sh or /bin/bash and compiler collection etc.

This article describes how to setup a lighttpd in chrooted jail under Debian and Ubuntu Linux. read more...
