  • Full screen not available in vmplayer 6 (on Linux)

    - by Simon
    I recently updated vmware player from 5.0.2 to 6.0.0, and now the "full screen" menu item is always grayed out. It happens with all my VMs, regardless of the guest OS. "Enter Unity" is still available for some reason. When I edit a VM to start up in full screen it works, but once I leave full screen I can't go back, which is really annoying. I've no clue where to start looking for the cause. I'm seeing this on Ubuntu 13.04 and OpenSUSE 12.3.

  • setting up bridged adapter for VPN server

    - by B. VB.
    I have an Ubuntu linux Linode server that I am trying to install OpenVPN on. I'm following the tutorials (which, it turns out, are quite incomplete). auto br0 iface br0 inet static address 192.168.0.10 network 192.168.0.0 netmask 255.255.255.0 broadcast 192.168.0.255 gateway 192.168.0.1 bridge_ports eth0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off When I add this chunk in my /etc/network/interfaces, and I restart networking, my eth0 interface does not have an IP and I cannot get on the network (I need to use a buggy, slow, and annoying AJAX term to do damage repair). Why does adding this screw everything up? Any tips on how to set up this bridged adapter?? Thanks in advance!

  • How to manage several Linux workstation like a cluster?

    - by Richard Zak
    How does one go about managing a lab of Linux workstations? I'd like for users to be able to log in, run their GUI apps (LibreOffice, Firefox, Eclipse, etc), and for the computers to be able to be used as compute nodes (OpenMPI). This part I'm fine with. But how can I centrally deploy a new software package or upgrade an installed package? How can I reload the entire OS on a given node, as if these workstations were part of a super computing cluster? Is there a nice program to help with setting up PXE booting and image management, and remotely managing packages? Ideally such a system would work with Ubuntu. If there isn't a nice package, how could this be set up manually?

  • Maximum memory allocation for 32bit linux kernel

    - by LedZeppelin
    I was reading this article that talks about how maximum amount of ram dedicated for kernel usage in 32 bit windows is 2GB even when the total amount of ram is 4GB. http://www.brianmadden.com/blogs/brianmadden/archive/2004/02/19/the-4gb-windows-memory-limit-what-does-it-really-mean.aspx\ Is this the same for 32bit linux environments like 32-bit ubuntu 10.04? IE is the max kernel allocation 2GB ram even if the total main memory 4GB? If you increase the total amount of memory to 64GB of ram by recompiling the kernel with the PAE option enabled, what is the maximum amount of ram you can dedicate for kernel usage? Is it still 2GB? Or can you increase it?

  • OpenVPN route missing

    - by dajuric
    I can connect to an OpenVPN server from Windows without any problems. But when I try to connect from Ubuntu 12.04 (start OpenVPN) I receive the following: OpenVPN needs a gateway parameter for a --route option and no default was specified by either --route-gateway or --ifconfig options SERVER IP: 161.53.X.X internal network: 10.0.0.0 / 8 What I need to do ? client configuration: client dev tap proto udp remote 161.53.X.X 1194 resolv-retry infinite nobind ca ca.crt cert client.crt key client.key ns-cert-type server comp-lzo verb 3 server conf: local 161.53.X.X port 1194 proto udp dev tap dev-node OpenVPN ca ca.crt cert server.crt key server.key # This file should be kept secret dh dh1024.pem # DHCP leases addresses to clients server-bridge # Push routes to the client to allow it # to reach other private subnets behind # the server.

  • Apache Subversion and Sudo - Why can't I resolve this hostname?

    - by Hollowsteps
    Okay, I made a mistake and I'll be the first to admit I'm new at this setup. I built a bare bones kit, installed Ubuntu on it, and attempted to set up a source control server for a project some friend and I were going to work on. Unfortunately, I screwed up. I followed a dodgy tutorial from 2005 and when it didn't work, started mixing and matching trying to get to the source of my problem. So now I sit before you, a broken and miserable man. Desperate to escape this annoying echo of 'Unable to resolve host computer.repositoryname.com', I uninstalled apache and subversion. That did not fix it. Next I tried to edit my /etc/hosts, going so far as to remove the reference to '127.0.1.1 computername'. Still I'm plagued. I know I messed up, is there any way to track down this wayward bug?

  • .htaccess does not ask the password

    - by Sarp Kaya
    I am using Ubuntu 12.04 and trying to use .htaccess on a page with apache2 server on it. My .htaccess file looks like this: AuthType Basic AuthName "Password Required" AuthBasicProvider file AuthUserFile /home/janeb/.htpasswd require valid-user /home/janeb/.htpasswd file is: inb351:$apr1$Ya4tzYvr$KCs3eyK1O2/c7Q9zRcwn.. and /etc/apache2/sites-available/default file is : UserDir public_html <Directory ~ "public_html/.*"> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> I restarted apache. I have tried to change require valid-user to require user inb351. Still no luck. I also tried AllowOverride with AuthConfig and AuthConfig Indexes. So I don't know what else to do, and yes every step that I have tried I restarted apache.

  • Sync Banshee library data.

    - by Dom
    I use Banshee to organise my music, I particularly like its scoring system and I have smart playlists based on it. However, I have two versions of my music library, one on each of my computers. As one of the computers is small I only have a favourite set of songs on that computer rather than my whole collection. The computers are not on a local network, but I do use Ubuntu One for file sharing between them. Is there any way I can synchronise song data (play count, score, skip count ...) and playlist data (including smart playlists that include songs based on this data) between the two computers? This would only be relevant of course for the songs that exist on both computers, the songs that exist on only one would need to be ignored. I did consider putting the library data file (I think it is .xml but I'm not sure) into the shared file and creating a symbolic link to it, but then I wouldn't be able to have a different set of songs on each computer. Thank you.

  • Attempting to caue packet loss with netem doesn't work - possibly because of NAT (but delay does work)

    - by tomdee
    I have traffic from a WIFI access point routed via an Ubuntu box. I have two network interfaces which are NATed *filter :INPUT ACCEPT [11:690] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [37:6224] -A FORWARD -s 192.168.2.0/24 -i eth1 -o eth0 -m conntrack --ctstate NEW -j ACCEPT -A FORWARD -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT COMMIT # Completed on Thu Mar 15 13:37:21 2012 # Generated by iptables-save v1.4.10 on Thu Mar 15 13:37:21 2012 *nat :PREROUTING ACCEPT [0:0] :INPUT ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] -A POSTROUTING -j MASQUERADE COMMIT If I run a ping app on an Android device connected to the WIFI network I can happily ping google. If I use netem to introduce some delay tc qdisc change dev eth0 root netem delay 100ms I can clearly see pings taking longer. If I use netem to introduce some packet loss tc qdisc change dev ifb0 root netem loss 50% then I see no change. Packet loss does work fine for locally generated traffic, just not for traffic coming in over the network that's being NATed. Any ideas how to sort this out?

  • What is a good solution for an adaptive iptables daemon?

    - by Matt
    I am running a series of web servers and already have a pretty good set of firewall rules set up, however I'm looking for something to monitor the traffic and add rules as needed. I have denyhosts monitoring for bad SSH logins, and that's great - but I'd love something I could apply to the whole machine that would help prevent bute force attacks against my web applications as well, and add rules to block IPs that display evidence of common attacks. I've seen APF, but it looks as though it hasn't been updated in several years. Is it still in use and would it be good for this? Also, what other solutions are out there that would manipulate iptables to behave in some adaptive fashion? I'm running Ubuntu Linux, if that helps.

  • GParted tells me my partition has 1.30 GiB used space but I cannot access its contents

    - by reprogrammer
    I've a ext4 partition (/dev/sda7) for my Linux. And, another (/dev/sda5) for keeping my data. When I installing Ubuntu 10.04 LTS, I set the mount point of /dev/sda5 to "/" and that of /dev/sda5 to "/data". GParted tells me that 1.30 GiB out of 70.12 GiB of /dev/sda5 has been used up. But, the mounted directory "/data" is empty. So, it looks like that my data is there but I cannot access it. Besides, when I set the mount point, I didn't check the "format" box. So, it shouldn't have been formatted. How can I check whether the partition has been formatted? How can I recover my files?

  • Samba PDC plus universal folder

    - by skids89
    I know how to configure samba on my ubuntu box to become a PDC however I need some select files to be accessible to multiple users. These files are beyond their personal files. I.E. users A-C need to be able to access a schedule saved as a spreadsheet. But user D does not and users B-D need to be able to access confidential employee info but user A does not. How do I set this up on top of the PDC structure? Any video tutorials would be a plus. Im new to linux so documentation is a confusing slow slog to learn. Thanks so much in advance!

  • apache not starting in vagrant vm

    - by jimmyjambles
    I used Puphpet.com to create a Vagrant VM to be used for web development. The problem I am having is that the VM cannot start apache on boot. $ sudo /etc/init.d/apache2 start * Starting web server apache2 * * The apache2 configtest failed. Output of config test was: apache2: Syntax error on line 36 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/authz_default.load: Cannot load /usr/lib/apache2/modules/mod_authz_default.so into server: /usr/lib/apache2/modules/mod_authz_default.so: cannot open shared object file: No such file or directory Action 'configtest' failed. The Apache error log may have more information. the system is ubuntu 12, not sure what modifications I have to make to the puppet config to fix the problem.

  • Grub os-probe showing deleted Windows installation

    - by Sanjay
    I recently purchased a Dell Vostro notebook with Ubuntu Netbook edition 10.04 pre-installed. I tried adding a partition and installed Windows XP but it didn't work out due to too many partitions in the system already. Now I have restored the laptop to factory setting using Dell Utility partition and the Windows partition is completely deleted, however my grub2 still shows Windows on /dev/sda2 sudo os-probe Microsoft Windows XP Professional (on /dev/sda2) Any ideas how to remove it from grub? I know I can remove /etc/grub.d/30_os-probe but I am more interested in why os-probe is showing the deleted partition.

  • Remap arrow keys to win+ijkl on linux

    - by Pengin
    I'd like to remap arrow keys to windows key plus ijkl. I can do this easily in Autohotkey on windows, but I'm struggling on Linux (Ubuntu lucid). I'd really like the solution to work independently of whether I'm using a window manager or not, and to involve modifying as few files as possible; I work on a lots of different machines and am always building new ones, so would like to minimise reconfig effort. I've tried to understand .Xmodmap, but couldn't make it work (was hard to find detailed docs on modifier keys). (Am also considering win+hjkl, but am probably not that hardcore)

  • Text Formatting toolbar continuously disappears in Impress (open office)

    - by Davide
    This is a very weird and annoying problem. Not sure if it's a bug or a "feature" I'm using OpenOffice 3.2 (within Ubuntu 10.04). The Text Formatting toolbars disappear in many circumstances, e.g. each time I click out of a writing area. It's becoming very time consuming to go to View-Toolbars-TextFormatting to re-enable it each time. 3 questions: is this expected behavior, and if so, is there any setting where I can change it? (note this wasn't happening in the past with other presentation I made)? is there a workaround, such as defining a shortcut like CTRL-whatever that would make the toolbar appearing without menu joggling? is anybody experiencing this too, especially someone using LibreOffice?

  • Which Linux variant to install on VirtualBox?

    - by Rohit
    Answer to one of my previous post suggested me to use VirtualBox for Sandbox experiments with malware files. I installed VirtualBox and now it demands a bootable CD to install the OS. I want Linux to be installed in it. I guess Debian or Ubuntu are the most popular variant. I want an ISO image that creates a bootable CD or a single DVD with that Linux variant and should include only the basic installation not much features. It should fit in at least 3 or 3.5 GB. Which one is more compatible with VirtualBox?

  • Slow website load with CNAME, fast when using IP

    - by Nate Strandberg
    I setup two DNS servers on my network: ns1.byte-werx.com && ns2.byte-werx.com I can ping the DNS servers and get a fairly good response time, when I dig them I also get a fairly reasonable response, but any website I filter through them is painfully slow (an upwards of 20+ seconds) -- verifiable by performing a tracert or attempting to access the URL in a browser. The DNS servers are running CentOS 6.3 and BIND9 with 500MB of memory (I figure that should be more than enough?). I have a reverse look-up zone (1.168.192) along with two website zones (www.byte-werx.com and www.stayhomedental.com) If I access the websites using their IP the page loads nearly instantly so I do not believe the issue is with the hosting server, but that is running Ubuntu Server 12.04 and Apache2 with 12GB memory. Any thoughts? I do not have the named.conf file in front of me but I can edit this post to include it if you feel it would be useful. Thanks for any advice!

  • Restarting rsyslog re-sends logs again

    - by Jay Taylor
    I am running Ubuntu 12.04.1 LTS on EC2. I have a bunch of application servers which are configured to forward their logs to a central server via rsyslog. Since putting in Nagios monitoring on the log files on the central server, I've been getting alerts indicating that particular application servers are failing to forward their logs to the centralized server. Logging into the machines and restarting the rsyslog service fixes the problem. However, rsyslog then re-transmits the logs again, resulting in duplicates on the collector. Why is it doing this?

  • Error mounting samba share, cannot mount block device xxxx read-only

    - by Jeff Ward
    After installing Ubuntu 12.04, I'm trying to mount a samba share from Windows under Linux, using a scripted command that's always worked, and the server hasn't changed. The error is as follows: $ mount -t cifs //<host>/<share> /media/<share> -o username=<user>,password=<pass> mount: block device //<host>/<share> is write-protected, mounting read-only mount: cannot mount block device //<host>/<share> read-only $ I've read a lot of discussions about permissions, but unfortunately, that wasn't the issue. I'm submitting my own answer below for reference, hope this helps someone else.

  • my.cnf in server directory, why

    - by Mellon
    On my Ubuntu machine, I have installed MySQL . I notice that there are /etc/my.cnf file which contain the content (only two lines): innodb_buffer_pool_size = 1G max_allowed_packet = 512M While there is also /etc/mysql/my.cnf with a long content like: # The MySQL database server configuration file. ... ... For me, it looks like both are configurations for MySQL server, but Why there are two my.cnf in different locations, can't the content to be merged to one my.cnf ? What is the purpose to have seperate my.cnf for MySQL server ?

  • A raw dump from a corrupted large file

    - by Masoud M.
    I have a large .rar file inside partion D (Windows7/NTFS). It's corrupted due to bad sector (I think) and when I copy it to another place (External-HDD) the system freezes after 88% of progress. I even tried to copy it with my Ubuntu and same problem occurred. Also I tried chkdsk and it dosen't fix it. I think my last chance is dump that file with a tool which ignores bad sectors and create a raw copy of it. Then I will repair the file with rar tools. But I can not found a tool to raw dump a specific file. (In linux there is dd tool but it dumps all partition and I can not use it) So, Is somebody know a tool to do a raw dump from a file?
