Debian :: Creating Offline Package Backups?
Apr 6, 2010
For a project I have had to migrate from FreeBSD to Linux and I have decided to choose Debian because I have had good experiences with it.However, since my main development machines are completely offline I have run into a little bit of trouble.Is there a way to specify a .deb package and get a tool to recursively list (and fetch) all dependency packages that are not included in the base install and put them in a folder?
I do not like to be tied to the internet (Never a good idea) and so this would save me a heap of trouble (and journeys to an online PC)Once I have these folders containing packages, then I can simple cd into one of them, dpkg -i the relevent .deb and not have to rely on the DVDs or worry about connecting to an online repositoryLife will be good!Suffice to say FreeBSD can do this well so I strongly believe that Debian will be able to aswell but since it is not normally done, I havn't found much on google about it

First Question: I have a very big volume (20+TB). When I try formatting it as ext4, I get the error message:
mke2fs 1.41.12 (17-May-2010) mkfs.ext4: Size of device /dev/sdc1 too big to be expressed in 32 bits using a blocksize of 4096. I understand that ext4 has a limit of 1EB (about a million terabytes), but a 32-bit limitation in e2fsprogs prevents me from creating a partition > 16TB.
Until e2fsprogs is updated to use 48-bit block addressing, it appears my choices are:Break up the volume into smaller volumes < 16TB, or Use xfs or zfs (I have already created a test xfs partition, and it works fine).
Does anyone have any opinions about which option is preferable? I have never used xfs before. Is it as robust as ext4? Is it as well supported by Ubuntu? What about zfs? Is it worth downloading from the ppa?
Second Question: I now have a huge amount of data to back up. In the old days, I remember making a full backup of a "big" 10 MB hard drive by taking a stack of floppies and inserting them one at a time into my floppy drive while my backup program split the backup into 1.4 MB chunks small enough to fit on a floppy.
I now have the same problem, but at a different scale. I need to back up 20+TB onto a stack of external 2TB drives. Is there any software package that can fragment a backup in this way?

We use Acronis for creating harddrive backups. The file format is "tib".We were able to mount the image using Acronis to make sure the files were restorable.

is there a way to get urls of the packages that have been updated and then download them in another computer? like this feature of ubuntu HOWTO: Download package dependencies for offline installation - Ubuntu Forums
its a simple feature and its present in smart and synaptic,yet its not in yast (or i havent found it yet.
i would use smart package manager but in my home connection for checking for updates ,yast is better ( smart downloads filelist.xml.gz that is very way biger than what yast downloads (though it enables smart to show filelist of package BEFORE installing) .so at home i can check for package update with yast ,buy downloading them is very hard. (my connectioon is very bad (i live in iran) and yast mirrors are NOT the best of servers ,so yast gets interrupted in middle downloading a rpm and the whole process is waiting for me to press retry ,so i cant do updates and installs overnight.btw is there some way to tell it to retry always or a number of times automatically? )
i need the url links of rpms so i download them separately and install them.

Is there any easy way to do offline package upgrades in Ubuntu? I was using debian's repository for the longest time to get individual packages, then found launchpad. Is there a script or something that will tell you what the dependencies are then let you copy them to a thumbdrive or something?
I know online upgrades are great but there are some cases where online isn't an option. Here's an example. Getting wine. There used to be this repository of .debs from the wine website, but now I can't find it. Launchpad has it, but it's all individual files.

I'm trying to make a local package server for my offline development network. Can anyone recommend a mirror containing every single package for CentOS 5.4 x86 as well as 64 bit? I've looked around but I haven't had too much luck yet.

I've been a DOS/Windows guy for 20 years, and recently became a SW test lab helper. My company uses CentOS for a lot, so I've become familiar with it, but obviously not as comfortable as I am with Windows.
Here's what I have planned:
machine: Core 2 Duo E8400, 8GB DDR2, 60GB SSD OS drive, ATI 4650 video card, other storage is flexible (I have 3 1TB drives and 4 750GB drives around that can be used in this machine.)
uses: HTPC, Network Storage, VMWare server host: SMTP, FTP server, and Web server virtual machines
I've figured out how to do much of this, but I haven't figured out how to do backups in Linux. I've been spoiled with Windows, with the built in backup system so simple to use. I find myself overwhelmed with the array of backup software, and unable to determine which to use. none of them seem to do everything I need them to do, but some come close, I think. I'm hoping someone here can help me out in figuring out which program to use and how to use it.
Here is what I need the backup software to do:
1. scheduled unattended backups, with alerts if the backups fail
2. a weekly full backup with incremental every 12 hours
3. removing the old backups when the new full backup runs, I would prefer to keep 2 weeks of backups, but that's not necessary
4. a GUI would be preferable, since my arthritic fingers don't always do as I want them to do. I typo things a lot, and the label worn off my backspace can attest to that.

How do you get Rsync to do incremental backups rather than full backups? At the moment I have a script that will create a backup folder (if it doesnt already exist) then copy the source files into the backup directory with the command
rsync $VERBOSE --exclude=$TARGET/ $EXCLUDE --exclude '/Ls-wtgl1c8/**' -rt --delete $source/ $TARGET/$source/ >> $LOG_FILE
Target is where the files will be backed up to Sources is the dir(s) to be backed up Exclude files is the list of files not to backup
log file is where the output will be saved to. At the moment it only does full backups, but I would only like to do incremental, how would this be achieved? Am I missing out an option in the Rsync that is required.

I installed ubuntu 10.10 server from an usb stick. I do not have access to a wired connection and do not have a CD drive, so now I need to configure the wireless connection.for that I need to have wireless-tools which if i am not wrong are not installed by default so the question is: how can I install the wireless-tools package from an usb using only command line? note: I got internet access from another ubuntu-desktop PC so i can download any package needed, etc.

Running against a situation here, for which I have solutions in mind, but for some reason or another they don't really strike me as "good" solutions.
I am making a customized for myself (eg with postgreSQL support) php package. Configure and make run fine; but upon make install the make tries to access httpd.conf in the $DESTDIR/etc/httpd
My first thought is: prior to 'make install' copy the file from /etc/httpd to the target dir;

I am backing up my debian server with rsnapshot which actually uses rsync to perform the backup. The backups are located in an external storage of size 1.4T .
[code]....
I tried to understand what this error message means and i founde that error code 12 : 12 Error in rsync protocol data stream I understand that when rsync find that a file on the target was changed , it will send only the block/blocks that contain the changes and in the destination rsync will create new file and not update the old one (new inod...) . I want to know if this error i get is due to full disk or perhaps it is some other factor

I am able to create a solaris package and hpux package from directory structure in a specific format rather than spec file but the same i can not do on linux . is there any way to do that . basically i can create the solaris package using command pkgtrans -s "source loc" "package location" all .we do not need any specfile here rather we create the package from the filesystem objects in a proper directory structures. again pkgadd -d option will install the datastream from a package but i did not find the same on linux.

I'm currently backupping our home data (pictures, videos, our CDs ripped to FLAC which I spent a lot of time to tag accurately ), totalling almost 300 Gb, on 2 external USB drives, one of which is meant to stay at a friend's. I left the factory msdos filesystem as it was, thinking it could be useful to be able to connect the drives to a windows machine with no problems. It's certainly useful to have «normal» data that I can take with me e.g. when visiting my family.
I'm simply using rsync manually, checking for suspicious changed or deleted file before commiting the change. I do that every 2 weeks or so.
Now I want to add a file integrity management to my backupping scheme: I want to be able to check that new data I'll be committing has not been tampered with (integrity check before updating tags on my main drive), and I want to be able to check that backupped data is still sane on my USB drives, especially if I need to recover from data corruption on my main drive.
Since I'm essentially mirroring the data, I thought run of the mill integrity software would let me just rsync the integrity database, and I'm done.
But after browsing through the docs of tripware, afick and the like, I fear they work only with absolute paths, so the database for my main drive wouldn't work for my USB drive, that's mounted elsewhere when I plug it in, obviously.
So, I feel I'm missing something. It looks to me I'm trying to solve a very common problem, how do people do it?
Did I miss a file integrity software that works with backups?
Is there a trick like using a symbolic link pointing to whatever file hierarchy I want to check, and have tripware/afick/... monitor that link?
Should I run a more elaborate backupping system than plain rsync? Which one? (Storebackup for instance looks promising since it involves md5 sums, but it's targetting a completely different problem, and I'm not sure I can use it at all for what I need.)

For testing I made a debian 8 dvd 1 installation on an usb stick. I selected desktop gui gnome and lxde. Both work. An ethernet 100mb cabel connection works. I can open iceweasel an surf websites.
If I open synaptic package manager and select vlc for installation or press 'mark all upgrades' I get this message. Insert disk debian gnulinux 8 jessie official dvd bin in drive.
Synaptic does not try to get packages from the internet.
Is a debian 8 dvd 1 installation an off line installation? The package system will not connect to the internet?

Two nights ago I was trying to diagnose what was wrong with my internet connection. I couldn't get web pages to load, IRC and ssh weren't connecting, and email wasn't downloading (I still use POP3). I didn't know what to use to check my internet connection. I did a ping, but I didn't know how to interpret the results. So without the internet, I was totally blind.
Are there documents anywhere which install with Debian which I can search offline when my internet connection dies?

I am using Debian 8, fully updated as of this writing.
I want to find a package or some way to get all my linux offline documentation in one place, be it through the web browser or an application, in the official reppos or not does not matter. I've already tried doc-central with apache2 but I get all sorts of error messages and something about no D-bus daemon started, i dont understand, because I;ve installed d-bus service latest version after the error. when I started doc-central correctly through almost blind luck (only once) I did not get any docs just the welcome message.
Is there an alternative to doc-central, a GUI type solution would be preferable. or at least some advice to properly configure doc-central and maybe that d-bus problem, because I clearly did something wrong, I have even tried to write the configuration through an example file for doc-central, but that did not do much, I've read that DocCentral is unstable so maybe I going at it the wrong way.

How do we perform offline patch management with Debian? This isn't a question about which tools to use on Debian to load the patch once it is on a CD and transferred to said offline computer via sneaker net. More, how do I keep said offline (or strictly firewalled) computer in synch?
Pardon me while I make a comparison to Solaris. I am in no way stating Solaris is better. It just happens to be my baseline of experience.In Solaris, I can download Cluster Patch Updates (CPU). So if I build a Solaris box with a CD that is a year or more old, I can download the latest CPU and get the box patched up to date, and from that point on sneaker-net patches as they appear.

I have Debien 7.8 Wheezy installed on my laptop, along with the GNOME desktop. As I absolutely hate the new GNOME layout I want to install MATE so I can get the classic GNOME 2 desktop back. But I have no internet connection here at home (I only have my phone for internet and I can't tether it).
So I'm wondering if it's possible for me to download all the packages and install MATE offline? I don't even know what all the packages are that I need.I can download the packages with my phone with no issue.
I installed Debian on my laptop with the Debian DVDs in case you were wondering. when I downloaded the Debian DVD ISOs, I only saw three ISO files, but the documentation said that it's a 10 DVD set. What happened to the other 7 DVD ISOs?

This is the command line switch I am using:
Code: Select allwget -p -k -e robots=off -U 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.6) Gecko/20070802 SeaMonkey/1.1.4' -r www.website.com
For some reason it seems to be downloading too much and taking forever for a small website. It seems that it was following alot of the external links that page linked to.
But when I tried:
Code: Select allwget -E -H -k -K -p www.website.com
It downloaded too little. How much depth I should use with -r? I just want to download a bunch of recipes for offline viewing while staying at a Greek mountain village. Also I don't want to be a prick and keep experimenting on people's webpages.

I have to do a .deb packet which will be placed in the repositories of the company.When this packet is installed, it only have to copy a plain text archive i've wrote before, to a path where it's being installed.The other requisite is that it have to watch if there's a program (vim) installed, if it's not installed, then the packet i have created shouldn't install.example:
# ls /home/loopin (as we see, this directory is empty)
# apt-get install mypacket

I am going to start reading about how to create Debian packages. Yet I would appreciate a simple overview about the process.Specifically, I would like to start with something simple: building a package with the Firefox 3.5.7 tar.gz pre-compiled binaries.If I understand correctly, the source files from Debian are modified in some way from the upstream provider, but my little Firefox project is not dealing with sources at all. The binaries are already compiled. So I'll appreciate a simple overview about creating a package from those Firefox binaries.
I realize the Firefox binaries can be installed as is, along with needing to create three sym links. That is not my goal. I figured starting with pre-compiled binaries will be an easier start into the Debian packaging process. Further, I prefer to install software with a package manager as that provides a system that is easier to maintain long-term.I suspect that an aide to my learning would be to extract the Iceweasel package and then draw similarities from that.

as I found an easy way to create a shortcut for the terminal on the net, I was trying to apply the same method to create a shortcut for gedit, which is a great text editor that I use very often.I don't know what when wrong but I must miss something because it obviously doesn't work.Here is what I did:1.ran: sudo gconf-editor2. went to /apps/metacity/keybinding_commands3. Set "command_2" to "gedit" (I also tried with "gedit-2" as it is the name of it in the list of the applications in the apps folder)4. went to to /apps/metacity/global_keybindings5. set "run_command_2" to the key I wanted, <Control><Shift>g(I tried as well with other combinations such as <Alt>g, <Shift>g, no successAnyone knows what I didn't do or did wrong?(I suppose that it comes for the name of the command on step 3, but I don't know what could be the name to put (if you guys could also tell me where to find a kind of list for the names to put in, like for others programs, it would be nice)
