That looks pretty cool. This product definitely seems more granular than most others.
I use Ganglia for our clusters.
This seems maybe better than Cacti. I was planning on building a Cacti server for just the master servers, but I may look into this.
I can +1 for Munin. We use Munin and Nagios for monitoring, and they are both pretty stellar. Nagios is more for 'watch and make sure nothing bad happens', which you didn't really mention in your post, but should be an integral part of any server 'dashboard'.
yup yup.
a few years ago a colleague suggested using fedora instead of centos. I musta flipped over like 4 magazine racks in the blind rage that followed.
Hey guys,
I'm trying to get a VNC server going on my laptop (running Linux Mint 13) and tightvncserver only knows how to create VNC servers for separate desktops. i.e. run vncserver and it will make a new desktop that I can't see on the local machine, but the viewing client controls the new desktop.
Anyone know of any other VNC that will be essentially a remote desktop? Either that, or somehow configure tightvncserver to not make new desktops, or find a way to switch the view to the new desktops (different from workspaces that i can switch by hitting ctrl-alt left/right).

I would probably choose Fedora over Ubuntu for a server class OS.So Ubuntu would have been out of the question too, then?
So basically, you're asking for vncviewer, right?
There's probably a tightvncviewer.
Or, something like tiger-vnc will include vncviewer. I don't know the package names for them, though.
It depends on your desktop environment. If you're using KDE or GNOME, it should have that capability built in or easily installable. In KDE, for instance, you can get to it by typing Desktop Sharing at the run dialog. Not sure about gnome.
Otherwise, I believe the package you want to look for is called "x11vnc".
So Ubuntu would have been out of the question too, then?
Sorry, I misunderstood what you meant by remote desktop.No no, i can view fine, but the vncserver creates a separate instance of a desktop and streams that instead of the desktop that I am currently using. Basically, when I connect to it via another computer, I get a brand new desktop that I can't see on the local machine.
You know what's sad? I know some *nix admins running the desktop versions with a GUI on their web servers. I told them they are begging for trouble but they won't listen.
What's wrong with that? >.>
So I got x11vnc and the server starts fine, but I can't connect to it with another computer because I guess the ports are blocked... The strange thing is that I can use TightVNC server on my win7 machine and view it from my linux laptop, but the reverse doesn't work. The only way I can view my linux desktop is via. listening mode... which is kind of annoying if I want to actually access it remotely.
I checked the firewall configuration on my linux machine and the firewall is off, but it is still refusing connections. Conversely, I do have a firewall on my win7 machine and I am able to connect to it from my linux machine no problem. Does this have something to do with my router blocking ports? It doesn't make sense that it's only blocking the ports on my linux machine but not my win7 machine.
argh =(
I'm running VMWare Workstation on my home machine and ESXi at work blows it out of the water in terms of options, SAN, backups and pretty much everything else. I've actually been thinking about taking my desktop at home and loading it up with CentOS and run ESXi on top of it at home for movie, music and storage etc. At the very least I would recommend to pony up the dough and buy workstation since it has snapshots and more options than player.
One major difference between the ESXi "Free" hypervisor and the paid one (which is what I use at work) is the fact that we get VMH (H for Host) software that controls the VMH servers. With the "Free" ESXi it is handled through a web interface.
orry, I misunderstood what you meant by remote desktop.
Since you're using MATE, (based on Gnome 2), gnome has something called vino. Or something like that. That's pretty much what you want, I think.
vinagre
but I don't think Mate uses it.
Wait, vino isn't a part of GNOME?
EDIT: Oh, I see. vino is a vnc server and vinagre is a vnc client.
What's the best place to start on learning Linux/Redhat so I understand fully on why Linux is used for server and network administration and the benefits with it. I am coming from a Windows server networking and desktop background and I want to see the other side of this OS and what advantages it does with the former enviroment. Thanks ahead guys.
Get some Virtual software (workstation is great but you have to pay, virtualbox is free), download CentOS (Which is Red Hat but free) and experiment with it.
For a full heads on I would recommend the official Red Hat documentation http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/index.html
For beginners there is an online guide which covers the basics http://www.1a-centosserver.com/
You also have the Centos wiki http://wiki.centos.org/
In any case I would recommend first start with a desktop distro if you know nothing about linux before jumping directly into server. That way you will have a better understanding about the innard working of linux before jumping to the difficult side
Thanks matey

I have a toshiba Qosmio x775 with geforece gtx 560m. The laptop supports hybrid graphics. I've installed ubuntu on it. It sucks my batter down because either both gpus are running at the same time, the fan continuously runs or it runs the nvidia all the time. I'm not sure. Is there a fix for this. I can't use linux as my main if my battery last for an hour.
Bumblebee -> http://bumblebee-project.org/
when i do sudo add-apt-repository ppa:bumblebee/stable I get these error messages:

Then when I try to install with sudo apt-get install bumblebee bumblebee-nvidia I get this message:

You are using ubuntu 12.10 and it's not supported
You will have to download the code and compile it yourself.
Oh okay. Is that simple to do?
Good to know, thanks for the update.Update on the cacti vs munin.
I installed and configured Cacti, but found out that snmp seems to fail to report proper disk sizes above 2-4TB. There may be some workarounds for using different MIBS, but it is not worth it for the time being. So, Cacti is currently no longer polling.
Installed and configured Munin. Fairly easy install on CentOS, using EPEL and RPMforge. Configured/linked additional ib0 network devices in the plugins. Very easy. Everything is working fine, and testing on a small group of servers.
+1 Munin
Guys how do I install Mint Cinnamon Distro when I allready have a Ubintu installed on it, without having access to a dvd?
How do it a bootable usb stick? I'm such a noob. I'm using ubintuUSB stick!
There's probably an installation guide on the Mint homepage guiding you through the necessary steps. I'd wager you'll need to install unetbootin, either through the Software Center or writingHow do it a bootable usb stick? I'm such a noob. I'm using ubintu
sudo apt-get install unetbootin
Would it be feasible to use a linux distro?, would it be possible to have them restore an image upon reboot and control which programs could run and allow bookable sessions?.
Hey so I dunno if this is the place to ask but...
I work for the NZ government. We deploy public internet PC's and wifi to 145 libraries throughout the country.
Currently the PC's all run Windows XP and we use Faronic's "deep freeze" and "anti executable" software to have the PC's restore their hard drive images upon reboot and prevent non approved programs from running. Some libraries also have a booking system so users get 30 minutes sessions.
We are looking at Windows 7 licencing (because users complain about xp). The licencing costs are horrendous.
Would it be feasible to use a linux distro?, would it be possible to have them restore an image upon reboot and control which programs could run and allow bookable sessions?.
hey guys, not sure where to post this but:
I am working towards being a Linux system administrator, and i've been studying the LPIC-1 currently. I was wondering if anyone here is a sys admin or has worked as one and could offer me advice tips etc.
Work at the Linux command line
Perform easy maintenance tasks: help users, add users to a larger system, backup and restore, shutdown and reboot
Install and configure a workstation (including X) and connect it to a LAN, or a standalone PC to the Internet.
There's probably an installation guide on the Mint homepage guiding you through the necessary steps. I'd wager you'll need to install unetbootin, either through the Software Center or writing
in a terminal. Then in that program, select the Mint iso you've downloaded to create the USB. Hope that puts you in the general direction, if not, ask!Code:sudo apt-get install unetbootin
Edit: For completeness, unetbootin is the program most people use to create bootable USB drives in Linux (except perhaps dd). Also, take any opportunity to read up on uncertain steps (like the sudo and apt-get commands if you use them and aren't familiar with them yet). It's the best way to improve
You wouldn't have to reinstall an image every time the system boots, that's a solution to a Windows XP problem that doesn't exist on Linux.
But yeah, it's super easy to have a kiosk type of setup based on Linux. Check out Red Hat's Desktop Deployment Guide that details some of the options you'll use. I suggest you start by playing around with CentOS 6 on a spare computer.
What's the preferred way of making a system where you have fairly free reign of application use but where the user environment is reset on reboot? I was thinking either deleting and recreating the home directories during bootup (which is easy but possibly a little less safe) or mounting /home to a ramdisk.
It's super-easy to really customise the desktop. If the only thing you want people to use is, say, the web, you can set it up with a barebones window manager that launches the web browser and restarts when the web browser is exited*.
Actually, what about using Chromium OS in that case? Has anybody here used that? That's the Google variant of Linux that essentially runs only Google Chrome (all applications are web apps).
That just looks like you need to adjust the boot order in your bios?Quick question... how to I reinstall windows only again?
(Im not going back to windows; just need to know)
I plug in windows usb, and it does not load while startup.
That just looks like you need to adjust the boot order in your bios?
And you're sure that your bios is set to boot from USB first?Nah, it just wont load, its a windows usb install.
And you're sure that your bios is set to boot from USB first?
If it is and it's not loading at all, I'd just assume that the image on the USB is damaged.
