Ubuntu :: Backing Up A Specific Server Package?
May 16, 2010
how would I backup a specific package. Really all I want is the configuration files.
the package I'm talking about is mumble-server, could I say rsync all the files that were installed, then if I wanted to drop it in just copy those back over?
If I had to wipe the installation and reinstall, could I install that package again then drop my backup copy back over it?
Dpkg tells me these are the files it installed.
Code:
dpkg-query -L mumble-server
/.
/var
/var/log
[Code].....

I'm trying to configure our mail server to block email from a specific sender reaching a specific recipient. In other words, if one of our employees is getting harassed by a 'stalker', how would one go about blocking, at the MTA (Sendmail) level, a specific sender email address from reaching a particular users inbox? We do not want to capture the email - simply block it before it consumes server resources.The Sendmail server (MTA) is a front end to our Exchange server so no user accounts exist on the Linux server. We simply use it as a SPAM and Virus scanner then forward clean email to the Exchange server.

I'm still trying to get comfortable with apt-get doing all my installing for me. The one question I have now is how do I find out where apt-get install "some_package" puts the package it installed for me?

I've been running my little server at home for a few months now, and I've noticed that Webmin has detected that I'm in need of over 100 updates. I'm a bit scared to run the updates because everything is working just fine right now, but a part of me still wants to run some of the updates.Now I know backing up the server would be a good idea to do before this happens. This server is a media server with videos, music and pictures taking up the majority of the hard drive space on the server. I just have one partition on the server, outside of the swap partition. I would like to back up everything on the server except the videos, music, and pictures, because if even an update messes with the server, I could always retrieve those, and the external hard drive I'm going to back up to wont be big enough to hold everything anyways.
if I were to backup up everything except for those directories that hold my videos, music, and pictures, and something were to go wrong, if I were to restore all of those, would I then be back to the state my system was at when I backed up? I've never done a back up and restore in a linux environment before. I just want to make sure that just doing that will be enough, because the last thing I want to do is hose my server after taking several weeks to get it to the working state that its at.

have had a server running for a very long time using Ubuntu Server 7.10, and I think it's passed time that I upgraded.I'll be installing fresh, and I've already backed up /var/www (as well as a home directory with a few files)I've only used this as a Web / SFTP / file server. Might there be any other directories that would be good to backup? I set it up so long ago and have made a few changes along the way.

What is the best method for backing up a VPS server? (A guest instance). I'm assuming you can't copy the image file while the VM is active. And if you stop the VM you have downtime.

If one accepts an update of a specific package via apt and decides the update isn't desired, what does one do? In other words, what is the most sensible and relatively easy way to rol-back to the previous version of that specific package without affecting anything else (dependencies aside of course).
I want to do this with a recent adobe plug in.

I have an Ubuntu server running Lucid. I'd like to be able to back up the hard drive in the server to an external hard drive. I try to plug in a drive via a USB port and it doesn't appear to mount automatically, as it does on the desktop version. Questions: 1) What/where should I be looking for to see if the drive is mounted? (I've looked in /dev and /media; no dice.) 2) What's the mount command I should use to manually mount the external hard drive? 3) What backup commands or programs, other than rsync, are recommended? (Nothing against rsync.)

At my work, we have an ISP that provides us with 2 connections with different IP addresses but at the moment they don't switch automatically if one fails, and can only work for outbound traffic.I tried to automate this with floating routing table on a CISCO 1711 router but then switching to the second link only happens when there's no longer a signal on the cable that's plugged into the router's interface directly -- and the failure most often happens somewhere in the middle. And that also does not make us available from outside.
Can anyone suggest a better way? Maybe an outside DNS server can have a second IP address recorded for our domain name?I found somewhere suggestions that a loadbalancer could solve that but these appliances are way too expensive.I also thought about using BGP but my router's RAM (128MB) is too small for the global routing table that BGP requires. And I also need an ISP (or better 2 ISPs) that provide BGP service. Before trying to convince others that we need to invest more into this, I'd like to know whether there are no easier ways.

I have a Samba server on a computer. I would like to backup the Samba files on a different computer that is a client in the Samba server network. I can easily drag and drop the Samba files onto the client. I would like to automate this process, and accomplish this using an update copy versus a copy full. How can I accomplish this as bash script? I had no luck using the 'cp' command.

All of a sudden when I ran an update with the usual
Code:
sudo apt-get upgrade
I got an input / output error for a specific file followed by an exit with dpkg returning error code 1.
In this case the package (ubuntu-docs) is not exactly life threatening, so I would prefer any update process to simply skip that particular package and move onto the ones that are getting held up. I then opened Synaptic Package Manager where I located the erroneous package. I then unmarked the particular package (ie the blob in front of the package name was green, and the status line shows zeroes for all categories (broken, upgrade/install, remove). So far so good. I then found the 'lock version' menu item under the packages menu. I clicked it, and ran the reload thing. After that thought the package was marked for deletion however, and I once again couldn't get by this one bad package.
So (tl/dr perhaps), how can I make Synaptic / apt-get / or whatever to skip this bad package for real so that I can update my system normally going forward? (Why is it that the whole upgrade process is that fragile by the way? Surely there must the the occasional dud package upgrade that people want to skip, no? Having the whole process grind to a halt because of one issue seems border line paranoid to me. Of course on a minimal server installation where every package counts this behavior makes sense perhaps, but on a IMHO bloated plain vanilla ubuntu install?

my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)

To allow specific IPs login to FTP server I'm using
Code:
<Limit LOGIN>
Deny from all
Allow from xx.xxx.xx.xx

But now I have question, is it possible to make something like this but just for specific users? For example there is user 'user1', how to allow login IP 77.77.77.77 to 'user1' account and deny all others ?

I need to search a bunch of files in a specific folder for a specific number and add all the numbers together to a total sum. I use Rsync everyday, everytime I run rsync i get a logfile (rsync output) witch contains the textstring "Total bytes sent: xxxxxx".
The "xxxxx" can vary in lenght. I need to extract the "xxxxxx" from each file and add the numbers together to a total size over a week or a month. Is this possible? And I wish to only use bash. One way of doing stuff at a time my friends .

how to set up a specific home server. What I'd like to do is set up my home server to check mail from various ISP's that use either POP3 or IMAP, then make that mail available to a local IMAP server.
Meaning... Server would just check every nn minutes to see if there is new mail at 2-3 different ISP's and if so, copy/move the messages to my server where I would use an IMAP client to check locally from my server. Before anyone mentions forwarding, neither of the ISP's does not offer forwarding services.
