Debian Configuration :: Accidentally Dist-upgraded Production Server To Unstable?
Apr 20, 2011
I made the terrible mistake of upgrading my live Debian Lenny web server with the the dist-upgrade option in apt-get. I didn't realize this was actually an unstable upgrade and now I have had to make all sorts of choices of what configuration files to keep or upgrade ect. The apache conf files were actually bad after the upgrade and I had to replace them with the backups (phew) and the system is currently still up and running. However my virtualmin installation is no longer working due to a issue with perl ( but thats another question I guess to ask somewhere else maybe ). Anyways... I'm very scared to restart because my server is co-located somewhere else and Im the only one who has ever worked on this server so I would need to go there and fix it myself if it doesn't restart. Basically I have two questions.. is there an easy way to move back to stable packages..If so is this recommended?
And also I'm currently trying to fix some broken dependencies in the package manager but when I run "sudo aptitude -f install" It keeps telling me it is going to remove all of these packages (listed below), some of which I know are very important to the system and I cannot figure out why it would keep trying to do this. I get an error on "phonon-backend-xine" whenever it tries to upgrade just saying this
"(gtk-update-icon-cache:12343): GdkPixbuf-WARNING **: Cannot open pixbuf loader module file '/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache': No such file or directory"
I installed some desktop related packages a while back like gnome-desktop and I know the package is related to this, but all I really care about is making sure the server stays online and not about the desktop packages. I tried just removing kdebase-runtime and anything else that is dependent on it, but it wont let me do anything at all without fixing this broken package.
I really would just like to go back to lenny stable again but I know its probably too late since I already had it install a new kernel and grub 2 (auto configuring my new grub.list)..

I just noticed that I had a sid line on my sources.list, at the end of all squeeze lines, and I've been updating more or less regularly. Does the ordering imply some sort of "preference", so that the first lines are preferred over the subsequent ones, or is it all about the latest version?After removing that line, and taking a look at my installed packages with synaptic, all the "latest versions" of the packages seem to be the ones that are already installed, and I click on properties, and there are no older versions available, only "##.##-### (testing)". Emphasis on "testing", rather than "sid" or "unstable". Of course I didn't check all of them, but about a dozen, and none deviated from that pattern. However, I went to double check on the web pages about the packages, and it seems that many of the squeeze's packages are at the same version of sid. I couldn't yet find one that is not.perhaps the sole fact that the sid line was on sources.list is enough to know that something happened -- as I don't recall having ever set up those configuration files about preferred sources/pins or however it's called), and suggestions on how to proceed? My hunch would be to just downgrade things gradually as they eventually fail (as I did with geeqie, which is why I suspect that there is some mess), but leave everything alone. Not try to fix what is not quite broken. And if it fails too often, go full-blown sid.

This is on my AMD64 Testing box...A couple days ago during an apt-get dist-upgrade, near the end I saw the errors below.
I haven't noticed anything broken, yet. I usually only see dkms errors when VBox squawks after an update and I run /etc/init.d vboxdrv setup.
The section of the results containing the errors to the end of the output:

updated my jessie by apt-get dist-upgrade and there was an error said there was something wrong with some database, and I needed to run some command, but after the upgrade I forgot to run the command. After I rebooted my system I found there was not any password needed for a normal user or the root. But if I change to the emergency mode, a root password is needed.

I am developing an application for Qt 4.6 and I am happy that Lucid has recently introduced this version of Qt in it's repository. However, a collegue of mine cannot install my application, and when I try to find out why I see that He is still looking at libqt4 version 4.5 in the repository. Notably, He recently made a dist-upgrade (I believe is the term) from Karmic to Jaunty and from Jaunty to Lucid.Does anyone know why he has a different repository, or perhaps even what I could do to get Him up to 4.6 in an apt-ly manner, so to speak?

I'm going to start using Debian as my desktop system rather than Ubuntu since I'm not really liking all the crazy eye candy and just wanted a fast and simple system. My main problem is networking, I guess I'll start off with my system specs and other information for problem solving.
My specs are:
- Intel Core i7 2600K CPU
- Gigabyte Z68X-UD3P-B3 Motherboard
- 8GB DDR3 1600Mhz RAM
I have a Realtek RTL8111/8168B Ethernet Adapter builtin to my motherboad which I am using, I could only get a basic connection, by basic I mean that it allowed me to connect to my local area network but not the internet. I then modified /etc/NetworkManager/NetworkManager.conf to change to managed=true this allowed me to use the internet, but the problem is, that it is a very unstable connection, the speed is very slow and it drops a lot! I have to carry on running /etc/init.d/network-manager restart twice to get my connection back, which lasts for about a minute.

Recently, I installed VVVVVV and discovered that when attempting to use fullscreen mode, the monitor displays "video mode not supported" for 640x480, 800x600, 1024x768, and auto. After googling around for an hour or two (and only finding stuff from 2008-09) I have created a new xorg.conf from Xorg -configure and nvidia-xconfig.

When I first did my install of Slackware 13.37, I installed the 2.6.38.4 kernel from /testing.
I did a "upgradepkg testing/kernel*.t?z"
Well just now I realized that there was a kernel-headers package in /testing, and I've heard that you should only use the kernel headers that glibc was compiled with.
So did I make a mistake installing the kernel-headers from /testing?
And if I revert back to the stock kernel-headers package, will I have to recompile all the programs I've compiled with the 2.6.38.4 headers?

Because of workers here in my company I need a very secure operating system for laptops so I have chosen Debian 7.8. The laptop is Acer Aspire E11 (E3-112-C4NE). This laptop has a built-in wifi card Aetheros AR9565 :
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
lspci -nn
02:00.0 Network controller [0280]: Atheros Communications Inc. AR9565 Wireless Network Adapter [168c:0036] (rev 01)
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Basically the stable 7.8 distribution cannot handle this wifi card, so I read on forums that I should upgrade my operating system. So I did as I read on the forum:
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
nano /etc/apt/sources.list
deb http://ftp.debian.org/debian wheezy-backports main contrib non-free
apt-get update
apt-get -t wheezy-backports install firmware-atheros
apt-get -t wheezy-backports install linux-image-amd64
reboot
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
After this the oprating system recognized the wifi card and loaded the "ath9k" driver. In the Grub the default operating system became :
Linux 3.16.0-0.bpo.4-686-pae
Because I want to restric the workers to access anything else except the designed inner network, I have uninstalled the Network Manager and set the network interfaces in the "/etc/network/interfaces" file as shown below:
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
[Code] ....
This works, when the operating system boots, it automatically connects to my hidden SSID wiofi network. I can ping other computers on the same IP subnet (10.139.252.xxx).
This computer should connect to an XP running under virtualbox, having the IP address of 10.40.138.153. But it does not. On another laptop, running Ubuntu 14.05, having the same network configuration, (10.139.252.102) connects to the same XP under virtualbox with no problem....
For Ubuntu nothing is required to be installed on virtualbox, no extension pack, no guest addition, nothing. When I want to connect to XP via rdp, it asks for username and password and after that only a blue or black blank screen and nothing else... Even on the XP I see no sign of any activity that somebody would like to connect.
Checking the network traffic (tcpdump, nast) I see that the two computers are communicating but after a while the communication stops. The rdp XP its in another IP subnet, but Ubuntu can connect without any problem, Debian not...

I was running 2.6.26 and I've recently upgraded to 2.6.32-trunk-amd64 along with other packages (mostly dependencies)... which possibly involved the network stack.
After this upgrade my home gateway stopped working and I'm clueless to where the problem may be.
I can see that the iptables are still there when I type:
iptables -t filter -L -v -n -x --line-numbers
iptables -t nat -L -v -n -x --line-numbers

while trying to get a game to work on wine I was surprised to find out that the wine version that ships with sid is 1.0.1 released in October 2005. So I installed the latest release I found at [URL] like this :
dpkg -i wine_1.1.42~winehq1-1_amd64.deb
The install failed, I think because I hadn't remove the old wine version, and that's when the joy-ride started. Impossible to remove wine to restart properly. (apt-get remove libwine wine and apt-get -f install didn't) After some googling I tried this :
dpkg -i --force-depends wine_1.1.42~winehq1-1_amd64.deb
This did install the wine version I wanted, and the game ran fine after that. However the result was a borked apt-get. Tried to remove wine again with the above commands, resulting in apt-get failing to do so because it tried installing wine-unstable and reported errors similar to these : E: Could not perform immediate configuration on 'wine-unstable'. see man 5 apt.conf under APT::Immediate-Configure for details.

This is my first time to set up a production web server and I got some few questions on our migrations:
1. Our website from the Web Hosting company already gaining 5000000 hits/month and 35000 unique visitors/month, problem is we only have 2x4mb dedicated line here in the office and one IBM x3650 m3 for our LAMP, you think guys its enough to handle that kind of traffic if we start moving our web server here in the office?
2. If I register www.example.com to GoDaddy for example, do I still need to setup a DNS (BIND) server on our side?
3. This is my current Apache config:
Apache/2.2.3 (CentOS) DAV/2 mod_fcgid/2.3.6 mod_auth_kerb/5.1 PHP/5.1.6 mod_python/3.2.8 Python/2.4.3 mod_ssl/2.2.3 OpenSSL/0.9.8e-fips-rhel5 mod_perl/2.0.4 Perl/v5.8.8 with PHP eAccelerator.
Anything to share to increase the performance of the web server?

I administer several web hosting (combined with mail relays and other services) production servers under Debian GNU/Linux. I began giving these public services two years ago via three boxes: the first is a gateway which controls traffic via iptables (it's attached to a DSL modem) between a public subnet (the DMZ) and a local network which connects several workstations. In the DMZ subnet I maintain two Pentium-III era boxes, they've grown in services since I set them up. Actually, I think I should buy new ones, but, you know, I want to save money and lenghten its life.
So, they've grown in data hosted, but I've never implemented a resilent backup system. I've set up some rsync tasks sheduled via cron jobs to copy the entire UNIX file system in each of the DMZ boxes, but I'd like to be prepared before an unexpected "real" crash of some HDD, I mean, some problem that renders a disk unusable.
AFAIK, sysadmins sync entire HD backups which are capable of recovering a system via swapping the unusable unit with the backup unit. Maybe the best fashion is to implement a RAID mirroring the unit, I'm I right? So, keeping my systems as they are, I mean, capable of using 4 parallel ATA units, what would you do? Use dump, rsync or some other way to have an operational second unit with an exact copy in a bootable second drive, in order to quickly swap it if the main unit fails?
Comes to my mind to partition a second unit (so making it bootable) and backup daily via rsync only those parts of the unix file system hierarchy which are necessary to boot a system properly. What do you think about this workaround?

i have a production server running RHEL 4.0 with 2x146 GB on a RAID 1 with OS and another storage with 2x300 GB on a RAID 1 with the application, it's the database and application.
No LVM was installing and configured before, and now the second array with mirror of 300 GB is running out of disk.
1. i have 2 new hdd to build another mirror 2 x 300GB.
how can i create a LVM to star using the vgextend anytime i need it?

I assume that the maturity of UFW is irrelevant because in the end it is just a front end for iptables...
But just in case, is UFW mature enough for production use on a web server?

My J2EE application is deployed in Weblogic 9.2 MP3 in Linux box.The problem is "api response time in production system is higher that test system( test system has more data and load w.r.t production .)"we got large amount of page fault in production Garbage collection log ,where as in test system (with same load ) page fault is Zero.And this page fault making my production system slow.In respect of JVM(JrockIt)both the system memory settings(Xms1024m -Xmx1024m -Xgcprio:throughput) are same.
Meminfo for Production:
MemTotal: 3866724 kB
MemFree: 1131748 kB
Buffers: 52304 kB[code].....
any system/kernel parameter set is missing in production which might cause this large amount of page fault. If any more information is required let me know?
Linux Version in Prod:
Linux version 2.6.18-53.el5 (brewbuilder@hs20-bc1-7.build.redhat.com) (gcc version 4.1.2 20070626 (Red Hat 4.1.2-14)) #1 SMP Wed Oct 10 16:34:19 EDT 2007[code]....

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.
My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.

After running a dist-upgrade (from stable to testing) KDE stopped working, all I get (after login in with lightdm) are the modals you can see in the attachments [1]. I do not think it is an X issue, because I can login using lightdm (and MATE is working fine).
I suspect this is because I had KDE installed before running the upgrade. The things I tried so far are:
- Runing "apt-get remove kdelibs-bin kdelibs5-data" . Then "apt-get autoremove". I did it to remove every KDE related package, after that, I ran "aptitude purge '~c' " to clean all config files. And finally "apt-get install kde-standard" to get KDE again.
- Removed .cache, .config and .kde folders. Also removed .lock files in .config folder, as I saw somewhere.
- Looked for some log files, but I could not find anything (I don't even know where to look really )
This is almost a fresh debian install so I don't mind breaking things, but I would like to get KDE working.

I have been using Debian for around two years now. I have a small home server running Debian stable i386 and keep it regularly updated (once or twice a week I perform apt-get update and afterwards apt-get dist-upgrade). The system was originally installed with Debian Wheezy and afterwards upgraded.
However, after entering dist-upgrade tonight, around 42 packages had to be updated. I agreed and afterwards got some errors. After apt-get install -f, the result is as follows:
Code:
Select allnickolay@tegulicium:$ sudo apt-get install -f
Reading package lists ... Done
Building dependency tree
Reading state information ... Done
[Code] ....
After rebooting the system, I am presented with the Debian Maintenance mode (root password for maintenance or Control-D to continue).
I tried dpkg --configure -a, apt-get install -f and aptitude install -f.
Unfortunately, still no resolution of the conflicts.
I assume this has to do something with the new Jessie 8.2 release ...

After yesterday's apt-get dist-upgrade, I lost my higher screen resolutions. Only had 800x600 and 640x480. After trying to re-install the Nvidia drivers several different ways without success, I ended up purging xorg and xserver and then starting from scratch, re-installing the drivers. In doing so, I either found the problem, or created another, ha.I think part of the problem was that I mixed Nvidia proprietary and debian installations and the update broke the drivers.I am now unable to install xorg or xserver because I can not remove/purge libgl1-nvidia-alternatives.
