hi guys,

just a quick one on virtualbox...

could i have centos 7 running virtual box...then host another 3 vm's on it that are running live at the same time?
or is this best for vmware?

i would like centos 7
then another centos7 vm
debian vm
slackware vm (headless)

its a i5 with 8gb RAM...the vm's wont be doing much work,prob ssh into each to setup things and experiment
maybe run a couple of small wordpress web sites...nothing drastic...

any advice on the best way to get this result?

I have VirtualBox up and running on my headless Centos 6 machine, am using http://sourceforge.net/projects/phpvirtualbox/ as a GUI, and created a virtual machine and installed Windows 7 on it.

I can access it using the VirtualBox console (via phpvirtualbox interface), however, only can see part of the screen and the mouse doesn't work properly. I can also access it using Windows Remote Desktop Connection using IP 192.168.1.200:9000 (why port 9000?), but again the mouse doesn't work.

I have the following ext packs installed on the server.

Do I need additional extensions to better interact with the guest? How are they installed? Thank you

I am running a headless Linux 17 media/NAS server. I have setup and tested the plexconnect script and it works. My only issue is that I can't figure out how to get the script to automatically run on startup. I tried using the GUI, but it doesn't seem to work.

To get it to work, I have to open terminal and navigate to the directory:

/usr/local/lib/PlexConnect/

Then run: sudo ./PlexConnect.py

The window has to remain open in order to keep running (which isn't an issue as it's headless). I'd just like to not have to login and start it each time the power goes out, or is rebooted.

I tried editing the crontab file and adding the following variations with no luck:
@reboot python /usr/local/lib/PlexConnect/PlexConnect.py
@reboot /usr/local/lib/PlexConnect/PlexConnect.py

Neither has worked. Does anyone know what I'm doing wrong?

Thanks!

It would be great if someone could share and provide some useful pointers/ advice on the feasibility of running .Net C# code on Linux Headless VPS Servers.

I have installed two virtual Linux(RHEL7)servers on VMWARE 11 and I need help on how to connect those servers to each other and my base machine is having windows 7 64 bit OS

So can anybody please help me out with this one

Hi Friends,

I recently install a Debian 8.0 Jessie on a Laptop Dell latitude E6540 with gnome 3.14+3.
But the problem is that it doesn't recongnize my multimedia buttons, I tried some methods but I didn't get results.

Code:

$showkey --scancodes
volume up   -- 0xe0 0x30 0xe0 0xb0
volume down -- 0xe0 0x2e 0xe0 0xae
volume mute -- 0xe0 0x20 0xe0 0xa0

$showkey --keycodes
volume up   -- 115
volume down -- 114
volume mute -- 113

xev
Code:

Volume up produces:

On Setting --> Keyboard --> Shortcuts --> Sound and Media :

Volume up Audio mute
Volume down Audio lower volume
Volume mute Audio raise volume

On dconf org.gnome.settings-deamon.plugins.media-keys

Volume up XF86AudioLowerVolume
Volume down XF86AudioRiseVolume
Volume mute XF86AudioMute

When I reassinged the keys on Settings>Keyboard>Shortcuts to F7, F8 and F9 it works, but when use the keys volume up, down and mute It doesn't show anything.

The same happens with Fn + Brightness keys, in this case it worked the first time but then stop to work I don't know why..

Please some help with this..

I am not sure what happened here, and I find it oddly disturbing that a Putty session from Window could do this, but here is what I did -

I was attempting to open a ssh redirect session from Putty command line on my W7 work PC to my home PC running Ubuntu 14.04. I've done this before with the Putty GUI and had no issues at all, but this time I was using cmd line and it never did connect. I ran this command:
Code:

putty -ssh -D 1080 -P 22 domain.com

The Putty window opened but never connected. I tried twice and when it didn't connect, I gave up and went back to the GUI. I connected with the GUI just fine, but after connecting an SSH session to my Ubuntu server at home, I noticed it was acting odd.

Long story short: It was in a "read-only" mode, saying the file system was read-only. I couldn't run apt-get update or even create a new folder in my Home folder or desktop. I remotely rebooted the machine and it never came back online.

When I got home I checked it, and it told me that Ubuntu had found some errors, and was asking if I wanted to correct them. I said yes and it took a short while, but then finally let me log back in.

After this, the box is about 90-95% back to normal except for a couple of odd things that I don't understand.

The main issue is that my Samba shared drives are no longer working. The fstab file looks the same and can connect to other machines, but nothing can connect back to the Ubuntu box. The folder permissions are correct also. I have a CentOS7 box, a Fedora laptop and a W7 box - none of them can connect to my Ubuntu box. I only run Samba and connect with it, even from Linux boxes, just to make it simple (since Windows is stupid and can't use NFS) - this has always worked in the past. Now for the life of me, I can't figure out why nothing will connect.

Is there a logfile or trouble-shooter I could look at it see what happened? It should be in /var/log somewhere, but I don't know where to start. SSH? Samba? The entire filesystem was read-only for a short while, so is there a FS or System log in /var/log?

I am kinda confused on this one, any help is appreciated.

I am trying to convert a PDF document from an Excel and PowerPoint document. I installed it and ran the command. It gives no warning.. Just doesn't create a new PDF document. I've successfully done this before, but I think it was a different server. I've checked file permissions, but don't think it is the issue (I've tried as a normal user and as root).

I could convert doc, docx, and txt files, but not xls, xlsx, ppt, and pptx files.

Thoughts why? Is there a verbose option or a log file which I could check for clues?

Thank you

I installed Debian 7.8.0 in text mode. While I configure eth0 through /etc/network/interface it assigned the IP but unable to ping to other machine in the network. I tried /etc/init.d/networking restart but still not working for me.

While I install GUI mode, it allows me configuration done through Network Manager and it pings good to other machine.

I have selected base install during the installation.
How to fix it under text mode?
