Ubuntu Servers :: How To Configure 8.04 Server To Check / Notify When Updates Are Available
Aug 15, 2010
Starting with Ubuntu Server 9.04, when I log in at times the OS smartly reports the number of updates available. I have a couple of questions of how to extend this functionality:
1) How could I back-port that functionality to 8.04 servers? Does that happen somewhere in the /etc/cron.daily/apt script? (Just the checking on # of packages needing updates, does not need to appear on the login screen.)
2) Then with that information, if the number >0 then use mailx to send admins an email. Since 9.04 and higher already do the first item, then in my mind #2 is the only thing needed for 9.04 and higher servers, and #1 is also needed for 8.04 boxes.

I know I can install updates using apt-get install updates but is there a way to check to see if updates are available without installing them?

I've been using Ubuntu 11.04 for a couple of weeks now, and I can't seem to get notify-send to work correctly (yes, I did install libnotify-bin)
Yesterday, I reinstalled Ubuntu 11.04 and the first thing I did was install libnotify-bin to try notify-send on a fresh install.
It worked fine after the reinstallation until I did sudo apt-get upgrade. Immediately after the updates finished, I tried notify-send again and it failed to display a notification.
No error messages, command exits correctly, no indication of anything going wrong except no notification pops up.
I'm on a lenovo thinkpad t420, 64bit ubuntu.

I'm running CentOS 5.4 and noticed that for the past month there haven't been any new updates showing up either on 'yum check-update' or 'yum update' (I'm interested in basic and security updates). Although this may be right, I wonder if there is an online reference where I can check the updates that are released for CentOS (security bulletins) and make sure if there is anything wrong with my update system.

Heres my situation. I have around 30+ systems running Karmic and more coming online everyday. I'd like to be able to have these updated via the local network to conserve net bandwidth. Is it possible to setup a single system which will download updates I specify, then make them available to the other systems on my network via some kind of local repo?
Of course I'm not looking to download EVERY repo, just the essential updates to the core OS. I really just want to eliminate that 45 min/256 file download that takes place each time I install a new system.

I'm running a syslog server on ubuntu 7.04. Can I somehow have it email me if it finds a certain thing in the log? For example. I'm running a PRI and when the PRI goes down, it logs a "DEACTIVED" in the log. I would like an email telling me this so I know to get on it and fix it.

I've been running denyhosts on Ubuntu 8.04 servers without any problems using the how-to found hereow that I have a new Ubuntu 10.04 server running, I thought I would just install denyhosts from the Ubuntu repository not realizing that the paths and filenames of the install are different from the how-to I am used to using.I figured out what the name of the new denyhosts config file is (at least new to me) and the new location, but I'm not sure about the "allowed-hosts" config file.Does anybody know where the new path for this file is and whether the filename is still the same?

I have used for a long time Filezilla FTP Server on a windows server, for multiple users in my company around the country.Lately the windows box died and I said let's try ubuntu server 9.10. I configured to my best as a Samba file server and from a speed point of view it works even faster than the Winbox.Now getting to FTP setup, I had the following problem when setting vsftpd.How can I enable more directories for the user, each with its own rights. By example, in Filezilla I had two folders for each user: one was a specific folder in which he could also write, and the other was read-only. They were setup with aliases, so that when user login, he sees one continous list of folders.I tried with symlink, but couldn't do it. Also I searched through the man page but also did not find something specific for this task I would appreciate any help you guys could give me in order to solve this issue, using the best practice for vsftpd. Also note that I am open to other FTP servers as well.

The last round of updates to 10.04 changed the initrd image, which I wasn't expecting. How do I check the updates to make sure that this is in fact the expected behavior? I.e., how do I go back and check which updates were supposed to have been installed, check what was actually installed, and see which one modified the initrd and why?

This is my first post to the forum
I've recently migrated my office PCs to ubuntu. My server doesn't server any big purpose but to provide Internet Connection to the rest of the nodes. Things were quite easier during the windows era using ICS.
Even in Ubuntu we were able to do it using the "shared network" option, simple & straight forward. But things got complicated only after installing "squid". Needless to say it brought in a lot of add ons as far as the http proxy serving is concerned & we are enjoying a better internet(http only) connectivity without any doubt. But we are not able to use our email clients, MS Outlook or Thunderbird
But to best of my knowledge squid strictly is a http proxy hence doesn't support handling requests on ports other than 80. (465 & 995 in my case)
Now I have two queries, 1. Can "Squid" really be used to do what I want here??? using iptables, port forwarding or any other mean
& 2. Can any one suggest a good pop3/imap proxy as good as squid is.

I am a newbie to linux and running ubuntu server 10.10 (no gui), I had it configured with a fixed ip address and all was fine till I changed internet poroviders and got issued with a new router.
I am trying to configure the server to reflect the new settings of the new service provider. here are the contents of /etc/network/interfaces
Code:
auto eth0
iface eth0 inet static
address 192.168.15.52
netmask 255.255.255.128
gateway 192.168.15.1
Just so I got this right can someone tell me if I am right here. address is the IP I wish to give to my server statically. and gateway is the ip of the router. When I try to ping the router I get
Code:
Ping 192.168.15.1 (192.168.15.1) 56(84) bytes of data.
From 192.168.15.1 icmp_seq=1 Destrination Host unreachable
When I try to ping the internet i get :
[Code]...
Is there anyone that can shed some light on where my problem may be. As i said before I got the new router I had been working with the server no problem.

I have setup two BIND9 servers as slaves for an internal Windows domain. I receive messages in my logs about a Windows server not being the master for the slave domain on BIND. I have placed the allow-notify statement in the global options section of named.conf, as well as setting the IP address in the masters section of the zone. I'm confused as to why I'm still getting this error message.

I recently upgraded to Fedora 15 from Fedora 14 using preupgrade. Most of the applications are working fine. But I am finding now that the OS does NOT check for updates. I am having to manually do the update each time although it is set to check for updates daily.
However, when I manually update using the code (below), it works fine.
Code:
yum update

I am trying to install and configure LTSP on a server for a HP thin client to boot off. The version of Ubuntu that I am using is 11.04 x86 and it is a fresh install on a dual core system with 2GB RAM. I followed a guide which comprised of these commands.
sudo apt-get install ltsp-server-standalone openssh-server sudo ltsp-build-client or if your on a 64-bit system with 32-bit machines do sudo ltsp-build-client arch i386 for editing the servers IP values use /etc/ltsp/dhcpd.conf after that you need to restart DHCP server sudo /etc/init.d/dhcp3-server restart
and update sshkeys -sudo ltsp-update-sshkeys and if you updated dhcpd.conf then you need to update you image also by typing in terminal ltsp-update-image
Everything seemed to install as it should but when I try to boot from the thin client it just times out and says no DHCP or proxy invites received. I turned DHCP off on the router and even tried another router, but I still get nothing. I am at a bit of a loose end and I hope someone on here can point me in the right direction of where I am going wrong.

I have been forbidden to enable automatic updates on our Ubuntu servers, for both security and regular packages.When I log into any of my four Ubuntu servers, the welcome message contains this:
39 packages can be updated.
26 updates are security updates.
However, when I run the Nagios plugin that monitors APT, I get:
% /usr/lib/nagios/plugins/check_apt
APT WARNING: 33 packages available for upgrade (0 critical updates).
I need to know how to properly detect that there are pending security updates, and regular updates. Once I can do that, I plan to write a Nagios script that will return WARNING for pending regular updates, and CRITICAL for pending security updates.

I have two DNS servers, one local and one remote, and I am trying to get them to talk to each other using views.
The problem I'm having is that the remote server can talk to the local one and receive zone files, but if I update the local server internal view, the remote doesn't receive the update. Here is my config:
Quote:
key "external" {
algorithm hmac-md5;
secret "xxxxx";
};
controls {
inet 127.0.0.1 allow { localhost; };
