Ubuntu Servers :: Management Tool For Multiple Server Instances - Webmin No Longer Supported
Jun 20, 2010
i started to look into upgrading my LTS ubuntu server instances to Lucid. one the notable things that i have discovered is the lack of support for Webmin; it seems that Debian is no longer supporting packages required by Webmin. But it also appears that ubuntu team believes that Webmin may actually cause problems as it works in a different way than that presumed by Ubuntu. so i am now left with no way to manage my 10+ instances of ubuntu server that i used for studying and research. it seems that i am left with cluster-ssh as an alternative. but are there other alternatives, ideally similar to webmin?

I'm looking for something to manage multiple machines.
Within a few weeks we're getting about 32 machines to manage.
We need to manage via SSH, SFTP and mySQL.
Is there something available which gives an overview of the machines and opens a terminal or sftp session with the selected machine, with a shortcut or something like that?

I have a test server on which I'd like to run up to 30 separate instances of a program as daemons, each running on a different IP address bound to the server. I've created a init script that takes an additional command line parameter - the last octet of the IP address. For example:
Code:
sudo myprog 40 start
sudo myprog 41 start
This would run instances of the program on IP addresses 192.168.1.40 and 192.168.1.41 respectively. But it's looking like this approach isn't doable if I wish to have any or all of these run at startup, as the links in the rcN.d directories can only link to the init script, not pass a parameter.

I've got two sound cards fitted, before I've always killed pulseaudio as a pain in the butt.
Without pulseaudio enabled I could run two audio apps simultaneously, ie run a SDR ( software defined radio) app , and listen to music or watch TV at the same time.
However, with puls audio running, you can only run one, either input to either output. So can a second instance of pulseaudio be run, master and slave perhaps ?

i'm trying to set up password-less SSH login between multiple instances on my server. My goal is to be able to monitor all instances, whether I created them or not, with Zenoss.
Current setup: 3 machines
A: Zenoss host- owned by me, Access via putty with my keypair
B: instance- owned by me, access via putty with my keypair
C: instance- owned by teammate, access via putty with their keypair
I'm able to set up password-less SSH login between the instances I have created (A to B), however, I cannot between my Zenoss monitoring instance and any instances not created by me(A to C). Whenever I try to copy the id_rsa.pub file to these instances, I keep getting a Permission denied(public key) error. I believe the problem is that I have log in to my instances using my keypair but must use the the other instances creator's keypair to access their instances.

I have to run multiple instances of apache on the same physical machine, as we have different OAM policies for different domains.is in the httpd.conf file can I have ServerName same in two instances of apache, like
ServerName: prod_machine (actual machine name)
In the vhconf files I do have different servernames for virtual hosts. Apache instances are running on same IP but different ports. I am including various vhost files in the main httpd.conf file. Can I skip servername in the main httpd.conf file and include different servernames in the virutal hosts configs. OS: Solaris10

Just a quick question, is there a system user management app that could be accessed via a website for red hat (or really any distro)? Something kinda like phpMyAdmin, but can do useradd, userdel, groupadd, etc. For remote admins who don't know how to use ssh or the command line.

I encountered a a dependency issue when trying to install Webmin on Ubuntu Server Edition 10.04 Beta1.
When you try to install webmin, libmd5-perl is not available in any of the lucid repositories:
I resolved the dependency prob by adding the following repository to my /etc/apt/sources.list: deb [url]
Then I did a sudo apt-get update then sudo apt-get install and libmd5-perl installed fine along with webadmin. BTW. I got a GPG error when doing a apt=get update because I did not import the public key for the debian repos I used to get libdm5-perl, which doesn't matter to me as I commented out the repos once I got libmd5-perl installed.

Looking for a test tool where I can fire up any number of ports (TCP and / or UDP) to listen on.
I am currently getting my using nc but its only 1 port at a time (i know I can open up multiple sessions but thats cumbersome), it can't do UDP, and it closes at the end of the session.
A friend has suggested socat but it looks pretty much the same except it can do UDP, but also cumbersome, I have to manually output to a different file per port, etc.
Basically its so I can quickly test firewall and NAT rules.

I'm was wondering if there is such a feature in webmin (or perhaps any other webgui) that would solve the following problem:
I need a few people to disable/enable users in a specific group, any only in that group.
Ex: Employee A logs in to webmin to enable an user account for employee B that is a member of the group "disabled by default".
Employee A are not able to disable/enable any accounts outside the "disabled by default"-group.
Would that be possible in webmin or any other webgui?

I use mpssh or pssh to issue commands to multiple servers. Problem is that some of the commands require pseudo terminal and won't work with these tools. This will work just fine: "ssh -t user@server command" as stated under SSH man: -t = Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g., when implementing menu services.
Multiple -t options force tty allocation, even if ssh has no local tty. So, is there a workaround for the above tools? Or is there any other tool for multi server administration that will work? If you are not sure what I am talking about just try executing "ssh user@server top" and "ssh -t user@server top" to know exactly the difference.

The great clock applet shows tasks and appointments from the evolution calendar. That's a great and fast overview of my agenda. But clicking a task of appointment opens a new instance from evolution every time, which is enormously annoying and really destroying productivity. I don't want 15 calendars open, I want the applet to behave like an index. So it should reuse the open instance and bring focus to the clicked appointment or task. How do I disable multiple instances of evolution?

I tried the google and browsing the known bugs in the sticky before posting this thread.On boot the machine is pegged at 100%. It is a dual-core with 4GB of ram and is running 10.04, 64bit. Also, as time goes on it eats up all the ram till theres maybe 32mb free. What happens is there are multiple 4-10+ identical processes running. seem to be gnome related.The machine sits idle on my floor and runs samba and apache/mysql/gallery for my test website that no on but myself visits.

I have enabled netbook-launcher-efl and like the interface quite a lot, but it only allows me to launch a single instance of each application. I was told in an unrelated thread that there should be a setting in gconf-editor that enables multiple instances to be launched, but I thought it would be more appropriate if I broke that out into a separate thread.

Using more than one instance of the same app is a real pita in Unity.If I have 3 (or more) pdf documents open in evince then there isn't a way to shift from one to the other using the mouse. Previously I had the windows on the taskbar and could click on the one I wanted. In Unity clicking on the evince icon on the launcher just brings ALL the instances of evince to the top - I still then have to shuffle the windows around to get the one I want.I've been trying to get used to Unity over the last few days, so maybe I am just doing it wrong, but if not then maybe I should file a bug report?

It is possible to run multiple instances of a jar executable. Is it possible that only a single instance of the jar runs? Wrappers like JSmooth or Launch4J can be made to run as a single instance. But since there are no such wrappers for linux, I need a way to restrict the jar to a single instance. How to embed the jar file into an executable such it runs a single instance?

I have been using totem player as my default video player. I've abstained from using VLC player considering the fact that it's got some security issues. Of late, I've installed and was mighty impressed by Mplayer because it could play .flv files which totem player couldn't. The only thing which I find irksome is its multiple instances. Can you please help me disable multiple instances in Mplayer. (I've experienced same problem in VLC player too, but right now I'm trying to stick with Mplayer)

How can I have multiple independent instances of Mozilla Firefox 3.5 on the same X server, but started from different user accounts (consequently, different profiles)?
Limited success was only with Xephyr :1, DISPLAY=:1 /usr/local/bin/firefox, but Xephyr has no Cygwin/X's "rootless" mode so it's not comfortable (see other question).
The idea is to have one Firefox instance for various "Serious Business" things and the other for regular browsing with dozens of add-ons securely isolated.

On Windows If I run Firefox as user jack, and then try to start another instance of firefox I will be unable to, as one is already running.If I choose to run firefox as administrator,then I can have two instances of firefox, separate from each other side by side, because they are under different user accounts.This does not seem to be true on Linux.As user jack if I start firefox, like on windows I am unable to start a new instance.If I open a terminal and change to root, set XAUTHORITY to jacks .Xauthority and try to start firefox as root....I get the error that firefox is already running.

I am running a script that can run as many as 10 simultaneous times. During my testing, i noticed that if the script starts while another is in process, it inherits the $1 variable, which is always different.For example, the script starts with "scripthere.sh entry1", anther one starts almsot at the same time "scripthere.sh entry2". As the script is running, the second instance inherits $1 from the first script. So instead of $1 entry2, it shows up as entry1. how I can store $1 so that its unique to that instance of the script only?
