Debian :: Why Extra Packages (Exim) Installed On System
Oct 17, 2010
Install One :
Installed Debian Squeeze onto my laptop using the netinst cd. During installation, I did not have access to the internet and installed "Standard System" during tasksel.
Install Two :
Installed Debian Sqeeze onto my desktop using the same netinst cd. However, this time I had connected the desktop to my router during installation. Similary installed "Standard System".
Both system later installed with KDE and working fine. Noticed that immediate after installation of the "Standard System", my desktop had more files installed eg. the exim package. Why the extra packages (eg exim) are installed? Are they actually required?
I want to make a rescue disc for debian such that if anything goes wrong everything can be restored to its original condition. whatever extra packages are installed they should also be put back. most importantly zimbra and its dependencies.
I upgraded my dedicated server using the do-release-upgrade command, and it seems to have installed many extra packages I do not require. This is a headless server in a datacentre, yet the upgrade caused me to install GUI packages I do not need. Is there a way to quickly remove all but the default server packages?
I have a dead system that was running Debian Linux (lenny). I can boot into emergency mode, but nothing else. I will likely have to reinstall Debian. I've read lots of things online about how to get a list of currently installed packages. Which is fine and dandy if the system is working and I can log into it. I'm basically wanting to extract such a list from a hard drive containing an installation I can't log into normally. I can access the filesystem just fine, and nothing related to aptitude has been damaged.
I have just installed Debian Lenny and was trying to upgrade the installed packages from the packages.debian.org site. when i asked synaptic to add the downloaded packages the would not appear, but when i checked the .xsessions file there are entries saying that the packages were being ingnored because they were either different versions, the MD5 did not match or even "can't find pkg". i have to use the local library to download the packages because i dont have an internet connection at home.
I just installed CentOS 5.4 Final on a 64 bit system. After install, I found a lot of 32 bit packages are also installed. Is it necessary for a pure 64 bit system to run (let's say, I will never want to run any 32 bit app on this system), or is it something I could have avoided during install?
I'm currently running 9.10 and am anticipating upgrading to 10.04 when it is released next week. I am however, running several packages from PPA's that were simply not working well at the versions included with 9.10 (I know specifically the 64-bit version of Flash and Wine are setup this way).
Since these installs are out of the scope of the official Ubuntu sources, how are these handled when I upgrade? More importantly, since some of these packages were just installed as a temporary fix until 10.04 came out, for some of them I'd like to remove the PPA version and reinstall the default version (since for several of them the 10.04 version has caught up to where it needs to be). Is there any way to identify all packages installed from PPA's on the system?
Exim: Is there away to block command when someone telnets to exim's port? Email won't send out unless they authenticate, but if there a way to total block them from typing all together, but still allow the server to receive email? IE, to block this:
Every time I install ubuntu I have to reinstall all the software from the software center and so. Now I already installed all software I need for this moment. Is there a way to take source files of those (installed) packages and save them some where else in order to reinstall them if i needed next time without need to INTERNET connection ???
Another question I wanna know about: How can I take a backup of my system as whole in order to get back to it if some problem happened. I used to use Acronis True Image and its alternatives to make a disk image. Is there is some thing similar in linux ?? is there better options ??
I was wondering how can I re-download only all currently installed packages. I would like to save them to removable media, because I use netinst disc to install, and on slow connection it's hell to download 1GB of packages with console-only.
How do you list only installed packages that were not installed automatically? I see in aptitude that it will list whether they were installed automatically or not, but it is hard to find them because the are a lot more installed automatically than non-automatically.
I can't remember if branch is the correct term but I am talking stable, testing or unstable.
i have looked through the dpkg and aptitude man pages but can't seem to find if there is a way to search which packages on the system are installed from a specific branch. Is there a way to do this?
if there is a way of downloading some extra packages and including some extra repositories that will automatically install during the main installation? With the option of a few settings being saved too... like for those that are used to windows having the gnome menu on the bottom.
I am promoting and convincing a lot of people to try Linux and I always recommend fedora as the OS of choice. I have no interest in creating my own distro, because I love Fedora. I just want to make sure these users can have all the codecs and little extras that makes computing fun without being a geek.My main issue is when I wipe their HDD and install Fedora, I then have to repeat the same tweaks and installs every time. This is my 7th time doing the exact same install and am looking for a quicker way.
I want to know how to install KDE on Ubuntu and Gnome on Kubuntu. The commands apt-get install ubuntu-desktop apt-get install kubuntu-desktop are not the solution, because they install all distro packages, and I want only the base of desktops KDE and Gnome.
I can install LXDE with apt-get install lxde instead of apt-get install lubuntu-desktop
I can install Xfce with apt-get install xfce4 instead of apt-get install xubuntu-desktop However, I could not do the same with KDE and Gnome.
if I wanted to install all the packages from the slackware cd in the extra dirctory do I have to install them one by one or is there a way to install them all at once?
I have realized that in not installing suggested packages I've missed out on a ton of doc files, which would really come in handy while I'm away from internet access.
Is there a way take a list of currently installed packages and find out which of them have doc packages available? Possibly install them in a single step? I have been playing around with aptitude and apt-rdepends, but I'm not quite sure how to go about this. Somehow take a list of installed packages, run it through an apt-cache search, and end up with a list of -doc packages to install? My bash-fu isn't the greatest, and I suppose this could be a bad idea to begin with.
I added 'testing' channel into my wheezy 'stable' box and installed packages comes from 'testing'. In this case, if I changed my mind to go back to 'stable', how could I downgrade packages updated by 'testing' channel?
I am trying to access my Debian system from a MB Pro. I believe I have all the necessary packages installed,but I unable to figure out how to actually connect, because I don't know what my hostname should be.On the Debian system, my username is jack and the hostname is aceraspire. jack@aceraspire:~$ hostnameaceraspireOn the mac terminal, I type ssh jack@aceraspire but it says ssh: Could not resolve hostname aceraspire: nodename nor servname provided, or not known.I feel like I'm missing the .edu or .com portion, but what is it supposed to be/how can I set it or find it?
I have a system that will not boot as /usr has been destroyed and I would like to get a list of installed packages before re-installing. I know that it's possible to get this using dpkg or apt, but I cannot run those.
Where in the filesystem is this information stored and what's the best way to get a list of installed apps from the files?
Now I would like to create a third file which contains only those packages which are present in package-a.txt but NOT in package-b.txt. The file should look like this:
Code:
package2 package4
Note: The world "install" is also to be removed for all packages. Using diff command I could get something like this:
Is it possible to do an aptitude remove for all packages installed in, say, the past hour? I'm looking for an easy way to keep track of lots of installed packages without having to look through the logs and write them all down.
Does aptitude(or apt-get) have the functionality to remove the packages installed from using build-dep? It just seems convenient if you want to remove a program that was built from source.
Can I keep the old 32bit_testing /home with all the hidden directories there when moving to 64bit_testing?
Is there a way to export a list of all installed packages in aptitude or synaptic, so that when reinstalling, it can be easily imported? (reinstalling the same system)
how to add packages to an existing Ubuntu ISO or LiveCD (Think like slipstreaming Windows Service Packs into Windows installation CDs, if that helps). I want to add things such as more games or the restricted extras plugins so that I don't have to go get them every time I install the OS on someone's computer, things like that. Not as important, but if it would be possible to remove packages
PS I'm not necessarily looking for a specific version, but I'm currently running 9.10 on one machine and 10.04 (soon to be 10.10) on another. A guide for any Ubuntu distro would be fine though. I'm just as interested in learning the theory of it as I am the actual execution.
I have downloaded fedora 9 iso to my xp os so I can dual boot my machine. I can't seem to find a place to plug up my RJ-45 to download the extras package in an RPM or a tar file so that I can transfer it onto my linux os so I need a wireless site to download from.
I have debian squeeze (and a bit of sid, actually). I wanted to install the newest pidgin, so I added at sources.list the sid repository, and tried to install pidgin, but it needed the newest perl-base 5.12.3-6 (from 5.10.1-17). So I let it upgrade. after that I realized that my mysql server isn't running, and actually this is my problem. So I tried reinstalling it, home:/home/amalia# apt-get install mysql-server-5.1. Reading package lists. Done Building dependency tree Reading state information. Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies:
If I do System-Preferences-Personal File Sharing it tells me that I can't enable sharing over the network because "the required packages are not installed on your system". It doesn't tell me WHAT packages I need to install!
I have my home network set up like so. My router has 4 ethernet ports so I have 1 hooked up to a network hub where I have 2 computers running windows xp and 1 running windows 95, on my other router port I have a desktop using ubuntu 11.04 and I have 2 windows 7 laptops and 1 ubuntu 11.04 laptop connecting wirelessly. All of the computers can see each other in my network map except for the ones running ubuntu. I can successfully ping every computer on my network from every computer without fail (even the ubuntu ones). The weird thing is that my ubuntu computers can see and use files from all of my windows computers but still nothing can see the ubuntu computers. I have set up samba to no avail and when I open file sharing and try to enable it on ubuntu it comes up with "this feature cannot be enabled because the required packages are not installed on your system." I have done clean installs of ubuntu 11.04 and 10.10 on both ubuntu computers and kept them up to date but the same problem persists. I have tried to do the same steps above with all of my computers wired but still nothing.
I got this bounceback recently and I'm unsure of how to correct the problem. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: [withheld]@sbcglobal.net SMTP error from remote mail server after MAIL FROM:<www-data@localhost> SIZE=2011: host sbcmx3.prodigy.net [207.115.21.22]: 553 5.5.4 <www-data@localhost>... Real domain name required for sender address
The headers for the offending message are as follows:
[Code]....
What's interesting is that in some places the correct domain is given, but the return-path and the envelope-from are set incorrectly. I should add a few things: this machine is used only to send email newsletters and for email generated by the websites; staff email is handled elsewhere the output of hostname is myhost the output of hostname -f is myhost.mydomain.net when I ran dpkg-reconfigure exim4-config, I set the system mail name to "localhost" so as to "'qualify' mail addresses without a domain name." I have a feeling this is the source of my problem, but when I set this to mydomain.net, I ran into another problem: I essentially disabled local mail. Messages to root (e.g., the results of cron jobs) would show up in my logs as root@mydomain.net. I want local mail to follow the rules set forth in /etc/aliases, not be converted to local-account@mydomain.net.
