Ubuntu Servers :: Update Apt-cacher Cache Automatically?
Mar 4, 2010
Is it possible to configure a cron script to update the packages in /var/cache/apt-cacher/packages? When a client machine updates a package, apt-cacher checks that it's cached package is up-to-date, and downloads a new version if it is not.
I'd like apt-cacher to check it's cached packages every night and download any updated ones, on the premise that since it exists in the apt-cacher cache, someone has that package installed and is going to want to update it. Is this possible? Does apt-cacher do this anyway, and I haven't noticed?

I am running ubuntu 10.10 server edition as apt-cacher server. How ever we have both 10.04 and 10.10 editions in our office. I have imported the cd cache of ubuntu version 10.04 and it is working fine. Now i want to import the cd cache of ubuntu version 10.10, for that i have to setup different server or i can import the cd cache in same server in different location? If in different location, how to import the cd cache?

I'm working on a web site. I'm sometimes finding that when I update a file, some mysterious force intercepts my changes and refuses to let me see them. I have confirmed that this mysterious force is a server cache.By adding a "?" to the end of the URL, I can see the changes I've made. Is there a way to somehow force my Internet provider to update the server cache?

I'm currently writing a script that will update the software packages on six ubuntu servers so I don't have to go in and update them manually constantly. Problem is, I'm not sure which command I should use to do this the most effective and safe way. Currently, I use sudo apt-get upgrade -y on my own machine, though I can see how this could be dangerous on production servers. I was in the IRC chat and I was told aptitude safe-upgrade is something I may want to look into. Is there a way I can only update security related stuff instead of everything? What do you guys suggest would be the best way going about this? Another issue I can foresee is certain packages that have an interactive prompt. While apt-get upgrade -y takes care of most of this, MySQL would fail with this as it opens up it's own prompt. Anyway I could make my script skip these types of prompts, so I can go back and update them later manually?

i was looking for a way to stop my menus taking a few seconds to load my icons when i first open them and found a few guides suggesting using the gtk-upate-icon-cache command, but with the any colour you like icon theme i'm using (stored in my home folder .icons directory) i kept getting a "gtk-update-icon-cache: The generated cache was invalid." fault i used the inbuilt facility in the acyl script to copy the icons to the usr/share/icons directory and tried the command again, this time using sudo gtk-update-icon-cache --force --ignore-theme-index /usr/share/icons/ACYL_Icon_Theme_0.8.1/ but i still get the same error. i tried with several of the custom icon themes i've installed and only 1 of the first 7 or 8 i tried successfully created the cache.

Do you have any idea on how to achieve my goal? Here is the scenario. As a requirement on our development process for every ticket we have we need to create a branch(svn) so that we can develop without disturbing other developer. Now for every checkout I made I need to create a vhost so that I can develop first in my local before deploying to the branch.The site I'm working on is based in Drupal. The files I checked out is just the all folder of Drupal. The core files are already in my local. So the script would grab the core files and copy the all folder in my checkout branch then put them in the vhost.So basically I need a script that will do these automatically for me:1. Setup a vhost Ex: My branch name is 1205googleplusone. Inside that branch has two folders, all and default. What I need only is the DocumentRoot should only point to all folder.2. Update the /etc/hosts Ex: The URL should be 1205googleplusone.domain.com. 3. Create a new database for the new site The script should create a new database and update the configuration.php

I'm using squid as a proxy in our organization. My problem is whenever the squid cache folder size exceeds 3 GB our proxy server starts to hang. Is there a way to write a script that it will automatically delete the squid cash when it exceeds the 3GB limit.

I am having trouble getting grub to automatically boot into ubuntu server. When I turn on my server the grub menu shows up and shows me the choices. They all work fine except that grub wont automatically select one. This wouldn't be too much of a problem but this is a headless server and I can't boot into ubuntu without a keyboard. I tried looking through the grub 2 documentation but nothing seemed to work when I edited the conf file.

openSUSE 11.3 with GNOME
Whenever I install a new application, that application's icon is broken (shows the generic "application" icon) until I run gtk-update-icon-cache on /usr/share/icons/hicolor. The package manager must not be updating it correctly, but for what reason I'm not sure.

i have just set up apt-cacher my file server to speed up package installs (and to reduce bandwidth use)
Im wondering if it is possible to use the apt-cacher with the mini iso, so each machine doesn't have to redownload the packages from the net?

I have used apt-cacher successfully for a long time on my home LAN. Its been great but after a recent server crash I decided to switch to apt-cacher-ng due to reports of lower memory footprint and faster response. Thats all well and good and after just a little mucking around it seems to be working.
But there are a few old (but still current) debs that I am having trouble importing into the apt-cacher-ng cache. Most of them were picked up after adding all the repos to my client and running apt-get update. But there are still a few that aren't.(the 2 biggest ones are from the same repo).My client machine runs apt-get update without fault but when I import (using the apt-cacher-ng web interface) it lists all the repos (including the one these debs should be in) but isn't importing any more of the debs. There are no errors showing.

dns cache serThis is probably more of a network question but I figured some one who is a network expert might know. Currently my organization has DNS servers. But my questions is would setting up a cache server improve the performance any? When I first thought about it i thought probably not. But since it stores information in ram that made me think maybe it would improve network performance a little.

I have a NFS server and I'm periodically cleaning the cache by using the following lines:
Code:
/bin/sync; /bin/echo 1 > /proc/sys/vm/drop_caches
/bin/sync; /bin/echo 2 > /proc/sys/vm/drop_caches
during the last days the cleaning process gets stucked at '/bin/echo 2', here's the process data:
Code:
27426 root 20 0 5488 704 576 R 100 0.0 896:06.34 /bin/echo 2
the process keeps running, so I find this more strange since it's not in zombie or D state.

rm -f /var/lib/rpm/__db*
yum update PackageKit
; yum clean all;

I have two Ubuntu PCs at home and I found out about apt-cacher as a means of reducing internet usage for updates. (my connection speeds aren't that good). When I install apt-cacher, is it possible for anyone on the internet to use my PC as a repository? If so, how can I allow only computers on my LAN to access the apt-cacher cache?

I would like to authenticate my laptop against LDAP server.
My setup works great when LDAP server is reachable.
I used the outdated howto: [URL] to configure libpam-ccreds in lucid.
If I try to login with network down I am getting message: You loged in using cashed credentials. and then Authentication failure.
sudo cc_dump looks OK.
Should I use pam-auth-update insted?

i am running Ubuntu Lucid x64 as a fileserver that shares its files via SFTP, NFS and Samba. Currently the hard disks are configured to go to standby if they are not needed. This works perfectly as long as no one browses the shares or my HTPC is running: That one repeatedly looks through the shares for new music or movies. In other words my problem is that the disks are spinning up a lot more often than they should have to. Additionally the spin-up time delays the response time while browsing. Since the machine has a lot of unused RAM i want to tell the kernel that it should keep the directory structure in memory. That way the disks would not need to spin up every time someone browses through the directories.

I was laughing about klackenfus's post with the ancient RH install, and then work has me dig up an old server that has been out of use for some time. It has some proprietary binaries installed that intentionally tries to hide files to prevent copying (and we are no longer paying for support or have install binaries), so a clean install is not preferable.
Basically it has been out of commission for so long, that the apt-get upgrade DL is larger than the /var partition (apt caches to /var/cache/apt/archives).
I can upgrade the bigger packages manually until I get under the threshold, but then I learn nothing new. So I'm curious if I can redirect the cache of apt to a specified folder either on the command line or via a config setting?
