Mar 12, 2010I'm rly poundering on the following problem. For our school assignment we need to make a liveCD (just a part of the assignment). I've stripped down a default ubuntu 9.10 . But I need to default keyboard layout to be azerty (belgium). When I run the liveCD in virtualbox and do dpkg -reconfigure console-setup it's all good.
But when I do it in chroot to change the liveCD, it gives an OK etc but when I pack it into an ISO again and run it ... Again US keyboard layout. Even on startup when I change the keymap it doesn't change to azerty... I rly don't know what to try now..
Ubuntu Servers :: SSH Chroot On A Per-User-Basis?
Mar 23, 2010I'm attempting to give a few buddies encrypted storage space through sftp using truecrypt.I have it worked out to the point where the truecrypt volume is automatically mounted when the user logs on, and dismounted when they log off.I would like to restrict each person to their individual home folders. This way, I can control exactly how much space each user is able to use (through the size of the truecrypt volume), while maintaining security through the network due to using SFTP.
I've been looking around, and the only thing I can see is restricting a large group of users to a single directory, this won't work, I need each person to be locked down to their personal home directory.My end goal is to have these volumes "mountable" in Windows through the use of Windows network drives (on a wide network, not through samba on local), or by using expandrive or a similar program. how I can lock these users to their respective home folders?

View 1 Replies View RelatedUbuntu Servers :: How To Setup SFTP In A Chroot
Aug 13, 2010I'm wanting to setup SFTP in a chroot, which is simply enough to do and I already have it working; however I also want it so that when they connect via SFTP it goes directly to their home directory. Currently I have the following in "/etc/ssh/sshd_config":
Code:
Subsystem sftp internal-sftp
Match Group sftp-users
ChrootDirectory /home
AllowTCPForwarding no
ForceCommand internal-sftp
Which works perfectly fine, however when they connect there are shown the contents of the "/home" directory which they then have to "cd username" to get to their home directory. This I do not like, and it confuses our clients who connect saying they can see "random folders that aren't mine", or some that think they've "hacked" the server. I really need it so upon connection they go to "username" directory. I can do this by using:
Code:
usermod -d /username username
Which changes the users home directory to "/username", and then upon connection it works just fine, they are taken directory to their home directory. However, I really really do not like the fact that "/etc/passwd" shows a different home directory to their real home directory, i.e it states "/username" when actually it is "/home/username".I've spent the entire day looking a different ways of doing it, and I can't come up with anything.
Ubuntu Security :: Chroot Without Internet Connection?
Oct 26, 2010I was hoping to set up a Kubuntu 10.04 Chroot on a PC with no internet access (I only have dialup anyway, not Broadband). All the information I have been able to find refers to downloading debootstrap in order to do this.I purchased a set of DVDs with all of the Ubuntu packages on them and created a single repository of them on my harddrive.Is there some way that I can create the Chroot using the packages on my hard drive without having to access the internet to download stuff as I do it?

Installation :: Chroot Ubuntu Using Live CD To Fix GRUB Rescue Prompt?
Jun 2, 2010Recently I messed up GRUB boot loader in my laptop installed with Ubuntu which resulted in grub rescue prompt. So I had to boot Ubuntu Live CD to get it fixed. Thought of blogging it, may be useful for some one.
This fix involves two steps. First one is to chroot into Ubuntu installation partition. Second one is to install the grub MBR (Master Boot Record). I am using Ubuntu Lucid 10.04 and Live CD also of same.

Ubuntu Installation :: Cannot Boot After Update - Udevadm - And No Chroot Command
Dec 20, 2010I installed Ubuntu Netbook Edition 10.10 on my Eee PC 901 (the one that has 2 SSD's). It all went fine, and I ran the update manager straight after install and config. It installed the updates (all 198 of them!) without error. I was prompted to restart, so I did. I got the error "udevadm trigger is not permitted while udev is unconfigured". I found out that this error is well documented, and I followed the guide at [url](apparently it affects all variants, not just UNE).
It went O.K., until I tried the command "sudo chroot /media/newroot". I got the error that "cannot run command '/bind/bash': no such file or directory". What should I do?
I cannot boot into and earlier kernel (problem/current one is 2.6.35-23-generic) I can only fix it via live USB stick.
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?
General :: Chroot - What Is Linkage Clash
Jan 30, 2010While reviewing information about chroot, I ran into something called linkage, specifically in reference to legacy and ABI, that they sometimes need to be ran in a chroot because the support libraries might clash in name or linkage with the regular root.

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?
