General :: Creating A Chroot Environment - Specifically With A Different Kernel ?
May 9, 2011I have successfully installed a Ubuntu chroot (Maverick) on a running Linux appliance (an old Thecus N5200PRO box) which has been running various services for me quite happily.
When I attempted to add a webcam (for snapshotting) to this mix, I've come up against a problem. Since the chroot by default uses the kernel of the Thecus appliance, there appears to (understandably) be no support for the Logitech UVC webcam in the appliances' kernel; consequently inside or outside the chroot I can't access the UVC webcam.
I think I can get around this in a simple way if I can run a standard Ubuntu Maverick 32-bit kernel in the chroot.
Does anyone know how to chroot with alternative kernels, or quite simply, how to get a UVC webcam accessible on a Thecus N5200PRO?

Debian Configuration :: Man-db In Chroot Ssh Environment
Aug 26, 2015I've been bashing around this for a couple of days, and could not find answer by using google. My debian 8.1.0 jessie runs perfectly fine. To perform SSH chroot jail, I issued an apt-get install makejail.
The ssh chroot environment runs great. I used makejail configuration scripts. The man pages are perfectly available from TTY login. Yet from a SSH session (chroot jailed) the man pages could not be found.
My MANPATH environment variable points at /usr/share/man
Running "mandb -c" from a SSH session as root tells:
0 man subdirectories contained newer manual pages.
0 manual pages were added.
0 stray cats were added.
0 old database entries were purged.
simply copying the contents of the /usr/share/man to /jail/usr/share/man
and running the "mandb -c" command gives lots of "dangling symlink" errors.
Perhaps the /jail directory need some dependent files, or change file permissions somewhere but I just couldn' t figure that out.
OpenSUSE Install :: How To Set Up A Chroot Environment
Aug 25, 2011I`m running openSUSE Tumbleweed so the first question is: can i run ONLY another openSUSE OS inside the environment ? or can i run any distro i want ?
My second question is how do it set up the environment to act just like my normal OS, with both root and user rights on it? and of course can i run X ?
And finally third question: after googling a bit i did not found a tutorial for openSUSE but i have seen that is says that i have mount and/or bind certain things, how do i make the same thing under openSUSE for the respective chroot environment?

Programming :: Obtaining Access To File In Chroot Environment From Usual Root?
Aug 1, 2011ccess to an iso file in chroot environment from my usual root (/) env..
Within the chroot environment I have an iso file placed... In my program I need to access this iso file and perform mount and other operations.. But I cant do this in the chroot environment as I have only basic commands here (ls,cp etc.. and no mount)
So how can I access this iso file from my program ? Is there something like a file-descriptor which I can associate with the file exit from the chroot env and access the file via this fd ?
Debian Configuration :: NVIDIA Driver 32bit Chroot On 64bit Host?
Mar 23, 2011I have 64bit debian 6 squeeze installed on my 64bit pc. I have an NVIDIA gpu which I have installed the drivers for and they work just fine. I also have a 32 bit chroot located at /32 which was created using debootstrap. The NVIDIA 64bit driver gives the option to install compatability driver libraries into the 32bit chroot. Whenever I run any application that uses opengl rendering within the chroot, they segfault. When I uninstalled and reinstalled the NVIDIA driver without installing the libraries to the chroot, and instead replaced them with mesa gl libraries, the programs complain about framebuffer missing. They do not segfault, and some programs that can use sdl instead will work fine. I have xhost + set to allow any programs in the chroot to use the host's xorg. I have the host's proc mounted to the chroot proc directory, and i also have dev mount --bind 'ed to the chroot.

Fedora X86/64bit :: Installing The Xen Runtime Environment Package Or The Xen Emulator For KVM?
Feb 28, 2009I recently gave the boot to Windows and installed Fedora 10. Under Windows, I was using VirtualBox for all of my virtualized computing needs. I had set up a virtual network with two virtual machines - one running Windows Server 2K3 and the other running Windows 2000 Pro. I could run both VMs at the same time and still use the host OS. Now I am trying a similar setup under Fedora, I am using VirtualBox to run Server 2K3 and Windows XP. The problem I encounter is that when I run one VM, one of my CPU cores rockets to 100% usage and the other hovers around 40% - 60% usage. Is there a way to enhance performance so I can run both VMs at the same time? Third, what would be the effects of me installing the Xen runtime environment package or the Xen emulator for KVM?

Fedora X86/64bit :: 32-bit Compatibility 32-bit Environment - Highlighted In The Terminal Output
Sep 19, 2009I am having issues getting a 32-bit environment to run something on my computer. Most people think this is a lame game, but I rather enjoy it and would like to continue playing it on this computer. I am running F11 x86_64 on an AMD Athlon 64 x2 6000+ Black Edition (OC'd at 3.4 in case anyone is wondering). I TRIED running yum to get the shared library referenced in the following message, but it gave conflicts on installation. Is there a way around this, such as installing a separate environment directory for just this game? Or is it just a lost cause?

The new problem is highlighted in the terminal output. I've searched the web for this issue, and it seems to be caused by an older lib included with glibc.i586, though I don't know how to verify or correct this. I tried a lot of things before finding this list.
General :: Chroot - What Is Linkage Clash

View 1 Replies View RelatedGeneral :: Make A Chroot Non Jail?
May 10, 2010how to prepare (before issuing the chroot command) directory links out of a chroot environment. I have done a bunch of reading, but not yet experimenting, about chroot. I mostly understand its main purpose of creating an environment in which it is safer to run untrusted software. But I want to use it for some other things, involving trusted software.
I want to create a directory tree in which the various top level directories are links to various directories in the main directory tree. For example, when running on a Debian based 64 bit system (where /lib has 64 bit .so files) I might want to create a root in which /lib links to the directory containing 32 bit .so files (same as /lib32 normally links to).
IIUC, chroot blocks soft links from getting outside. So I could create a directory containing lib as the desired soft link, but if I did chroot to that directory, the link would no longer point where I wanted. Is that correct? IIUC, I can't do a hard link to a directory. Is that correct? How would you create a directory link that would point out of a chroot "jail"? (Yes I do understand that is contrary to the common purpose for a chroot).
From reading, again not yet experimenting, I think mounting an aufs might do it. It looks like aufs might be used to mount a directory into another directory. Is that correct? Am I missing some easier way to mount a directory into a directory? Would such an aufs mount link out of the chroot? Or suffer the same fate as a soft link?

May 13, 2010I have never set-up a chroot-jailed environment before and I am afraid I need some help to do it well.To explain shortly what this is all about: I have a webserver to which users send python scripts to process various files that are stored on the server (the system is for Research purpose).Everyday a cron job starts the execution of the uploaded scripts via a command of this kind: /usr/bin/python script_file.pyAll of this is really insecure and I would like to create a jail in which I would copy the necessary files (uploaded scripts, files to process, python binary and dependencies).
I already looked at various utilities to create jails but none of them seemed up-to-date or were lacking solid documentation (ie. the links proposed in How can I run an untrusted python script)Could anyone guide me to a viable solution to my problem? like a working example of a script that creates a jail, put some files in it and executes a python script?
General :: Failed To Su After Making A Chroot Jail
Oct 6, 2010On a 64 bit CentOS host I am using script make_chroot_jail.sh to put a user in a jail, not permitting it to see anything expect it's home at /home/jail/home/user1.

I have fixed this by copying some missed libraries:
But now, when trying to connect to user1 typing su user1 and then typing it's password, i am getting this error: could not open session
So the question is how to connect to user1 in this situation?
Here are the permissions of some files, this might be helpful in order to provide a solution:
After some modifications i managed to connect to user1, but the session closes immediately! I guess this a PAM issue, however cant find a way to fix it.
Here the log entry for close action from /val/log/secure:

Apr 20, 2010I would like to create a logon script, for specific user, under ssh connection, to backup several directories in a USB device; this backup will run when the device was plugged in and the user logs in server. My knowledge of linux isn't very deeply now, and some questions are in my head. I would like to make this in a chroot jail, and the user log in through ssh connection doesn't have to make nothing, the logon script will mount the USB device and make the backup (using rsync or whatever), and exit the ssh connection when it finish.
Anyway the questions are:
- is possible that a user in a chroot jail mount a USB device?
- from this jail, the directories outside of the jail could be available or need to be bind or something for this task?
- it will be better to "jail" all the directories to backup, inside de chroot path (almost would be samba sharing for Windows clients)?
General :: Share A Large Number Of Files Into Chroot Env?
Aug 17, 2010I understand that chroot is usually used to provide security, however, for my issue, security is a big don't care. I am very new to using chroot and don't fully understand how the chroot'd env works.
problem: Trying to use a vendor supplied cross compile environment. The environment runs as a chroot'd env and works just fine. I have a large number of additional modules that I wish to compile in the chroot'd environment. FYI, these modules are also (succesfully) compiled for other targets not using chroot'd env's. Copying the source files into the the chroot environment is not an option (don't have hours to wait for copies to finish and it would break the make system). Having them live in the environment is also not an option (the chroot build is a tiny part of the build process and we cannot revamp our entire source tree to accommodate it).
I am looking for a way to have the compiler in the chroot'd env have access to a path that is outside of the env and typically higher up in the same path that holds the chroot'd env. I have tried soft links (they don't work as expected). Hard links only work for single files and there are 10's of thousands of files that would need to be linked. I am not sure how I would go about exporting the additional files and then mounting the exported files in the chroot'd env (or if that would even work).

Sep 26, 2010I tried setting up sftp for my users. Each of my user have their home directory at "/var/www/public_html/$USER". When my users are using sftp, they can only see their own directories and unable to move to other locations of the system. I followed through the following tutorials: [URL]
The users are able to sftp into the system successfully. However, they are able to see the whole system. Somehow, it appears that the users are not jailed in their home directory although in the tutorial it states otherwise. The difference of my system against the tutorial is that I am using Dropbear for SSH server while it is using Openssh server. Although dropbear does not support sftp, I am able to login through sftp through the use of sftp-server. For the internal mechanics, I am not sure how though.
Assuming that when I tried to SFTP, the sftp-server is ran with the sshd_config, then everything should be working fine right? Do i need to run chroot command at all? The following is the procedure I used to attempt the objective:
1) Add a new user to the group: SFTPonly
2) Chown user:SFTPonly user/home/directory
2) Modify the sshd_config to what is reflected in the tutorial and other paths.
General :: Chroot Error - Cannot Change Root Directory To /jail - Operation Not Permitted

Aug 12, 2010Basically they all cover running a 32bit app running on 64bit host and so on.I want to have an isolated system in total chroot (running lighttpd, mysql, ssh, etc from there).(For security reasons I have to isolate the dev from the live one.) So I installed the chroot environment, mounted all the neccessary things and chrooted in. Everything went fine. Edited /etc/ssh/sshd_config to use port 22222 instead of 22. Used service ssh start then. It says service running but if I try this: ssh -p 22222 localhost I get "Connection refused". The chrooted is system is very minimal so far so there is no firewall, hosts.allow/deny or anything.
ps.: The chroot environment will be a development area as I already mentioned. I thought chroot is the easiest way but if you say KVM is better or something I can go for it. The machine is easily capable of running even 10 VMs easily.
