Ubuntu Servers :: Completely Chroot Enviornoment Where Every Single Service Is In Chroot Mode (bind,mysql, Postfix)?
Jul 12, 2011recently we decided to make our own panel (like Plesk or cPanel) but for Ubuntu and it will be licenced under GPL (like any other professional sofware).want to make a panel not only that fits our needs but also the needs of other system administrators and domain owners. We researched other panels and found out that non of them has security/look/ease of use in one package. Bad codig is another problem found in other panels.I made a short overwiev of what I think we have to have in the beginning.I Security :1. Completely chroot enviornoment where every single service is in chroot mode (bind,mysql, postfix, .... )2. Easily managed IPtables trough web-based interface. 3. Coding rules has to be strict.
II Software selection :

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?

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).
Server :: SSH Chroot'ed User Can't Write Files / Solve It?
May 31, 2011I am having an issue with a Chrooted SFTP User not being able to write files.
The permissions are setup correctly as if I remove the Chroot the user can write files correctly.
User has a transfer folder which they should be able to write files to and read from, this works correctly until I apply the snippet from sshd_config file below then the user can only read files. I have tried tweaking the permissions but this doesn't seem to have helped at all.code...

Ubuntu :: Reinstall The FTP Servers They Won't Start Because The Config Files Are Gone?
Mar 31, 2010I built out a headless VMWare v2.0.2 Server. I managed to work all that out but now I'm having some trouble getting my virtual machines on the server. I installed both proftpd and vsftpd but neither server lets me log in. 'Login Failed' is always returned (using the only account on the machine - created during the install).
So I decided to install samba, but samba chokes on large files. I tried over and over again to copy a 10GB VMDK file over samba and it gets to 5% or so and suddenly tells me there is a network problem and dies (which there is no network problem as these machines are all on the same subnet plugged into the same gigabit switch).
So now I'm back to FTP. Unfortunately when I ran apt-get remove proftpd, it didn't remove any of the config files (/etc/proftpd/*) so I manually deleted them. Now when I try to reinstall the FTP servers they won't start because the config files are gone. What's the apt-get syntax to completely uninstall these servers as if they had never been installed so I can start clean? I really don't want to have to do a complete system re-install just to fix 300KB FTP servers.

View 9 Replies View RelatedUbuntu :: Uninstall ATI Drivers And Reinstall Original Files
Jun 12, 2011I am running a recently installed minimal install. I am having some fun building the system up but trying to keep things slim. I have installed the ATI catalyst drivers working from the tutorial here under 'Installing the Restricted Drivers Manually': [URL]... After successfully getting the ATI driver running, I realise I really don't need or want it and am wanting to uninstall it completely and return the config to the way it was. Some of that I can do with the aid of some of the links I have found but installing the ATI drivers no doubt killed some of the packages that were there in the first place (graphics was fine in the first place incidentally). Question: What might these squashed packages be so I can reinstall them and have graphics setup as it was before I installed the ATI drivers and how can I remove all trace of the ATI drivers?
View 8 Replies View RelatedUbuntu Installation :: Reinstall Apache2 - Recreating Config Files
May 11, 2010I've deleted /etc/apache2 and did run:
Code:
sudo apt-get -o DPkg::Options::="--force-confmiss" --reinstall install apache2.2-common
to get the default config back.
But starting the server via:
Code:
sudo /etc/init.d/apache2
results in:
Code:
Syntax error on line 161 of /etc/apache2/apache2.conf:
Invalid command 'Order', perhaps misspelled or defined by a module not included in the server configuration
line 160-163 look like this:
Code:
<Files ~ "^.ht">
Order Allow,Deny # line in question
Deny from all
</Files>
The funny thing is that the exact same definition is in a debian lenny server config on another server. So why did this install a not working config?
I just removed apache2 via:
Code:
sudo aptitude remove apache2
sudo rm -r /etc/apache2
and reinstalled it via:
Code:
sudo aptitude install apache2
which also did not fix the config bug?
For testing I installed apache2 on another ubuntu 9.10 and did just copy the folder /etc/apache2 to my local installation - this fixed the problem. Still, why cant I reinstall apache2 with a working config?
Ubuntu Servers :: Reinstall XAPP And Copy The Index.php Files From Another Comp?
Apr 18, 2010First off. I'm not using Ubuntu Server. But I'm trying to get XAMPP set up so I can test Wordpress themes I make. Using 9.10. I got XAMPP installed using the Instructions from Apache Friends. When I went to Localhost I got the language page. Selected English but nothing happened.
Here's my Index.php:
Code:
<?php
if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) {
$uri = 'https://';
} else {
$uri = 'http://';
}
$uri .= $_SERVER['HTTP_HOST'];
header('Location: '.$uri.'/xampp/');
exit;
?>
Something is wrong with the XAMPP installation :-( I searched and found a couple Index.php files. Deleted one. And now when I go to localhost I get a "Index of" page.I removed the XAMPP folder, Deleted Apache, PHP from Synaptic(They got reinstalled when i reinstalled XAMPP btw). Installed LAMP but it still does it. Maybe reinstall XAPP and copy the index.php files from another Comp?.
Ubuntu Installation :: Tar.gz And Tar.bz2 Files - Unable To Access The Internet To Reinstall The Packages
Aug 10, 2010I accidentally removed my network manager (gnome) from my system (via synaptic) and hence have not been able to have access to the internet to reinstall the packages. I have experimented with many commands (with help from others) in terminal with little success.
What I now did was downloaded a 'NetworkManager-0.8.0.999.tar.gz' file and a 'NetworkManager-0.8.1.tar.bz2' file (from a different comp) and have placed them onto my desktop. I have read the INSTALL instructions within and it is a tad complex for me as I am new to Linux. I understand I have to extract the files and compile them into a new folder (I think I would choose a file in the /home directory)- how would I go about doing this? Following this, I need to './configure' or 'make' or 'make install' the files

View 2 Replies View RelatedOpenSUSE Install :: 11.1- Completely Reinstall Grub & Its Stage1&2 Files?
Mar 11, 2010Due to lack of concentration, I inadvertantly ran PClinux(2009-2)'s "install.sh" while I was in openSuse 11.1. This file says:
grub --device-map=/boot/grub/device.map --batch <<EOF
root (hd0,6)
setup --stage2=/boot/grub/stage2 (hd0,6)
quit
EOF
I soon found out that Suse 11.1 would no longer boot from boot.ini (using bootpart) because the boot process now brings up PCLOS (in /dev/sda6) rather than Suse 11.1 sitting in /dev/sda5. No problem, I thought, I'll boot from the Suse install DVD, use repair, and away I go. Wrong. After grinding, it started mentioning about generating something for sda13, which is my last partition. NTFS! So I bailed before it got too far. I even tried "rescue" option on the DVD, command prompt, and grub commands to reinstall via "setup.
Then I tried to use Super Grub Disk (.97xx) to reinstall the PBR, stage 1 and stage 2 loaders. Didn't change a thing. So then I used Grub4DOS and got into my Suse 11.1 installation using this in its menu.lst:
title openSUSE 11.1 - 2.6.27.45-0.1
[Code]...
Worked fine, and is now my (only) method of booting to 11.1. So obviously it's bypassing stage 1 and 2 files, using it's native Grub4DOS code. But then I tried Yast-Bootloader to reinstall Grub's files. No difference. Then I used the advanced part to "write bootloader code to disk" No difference. Even tried "propose a new boot scheme" (or whatnot) no difference. After looking at all this, I've come to the conclusion that the PBR code in sda5 is scraunched, and/or stage 1 code (although it's still the original date), or stage 2 (which definitely had a new timestamp of when I committed the fatal error by executing PCLOS's "install.sh".
So my question is this: How do I do a good COMPLETE re-install of Suse's version of the grub files? Because, for sure, grub commands like "setup --stage2=/boot/grub/stage2 (hd0,5), and variations thereof, certainly aren't doing it? My reasoning is that I should make sure that all the boot files get restored/confirmed as "originally installed by Suse".
