  • Why does Ubuntu keep trying to connect to a WiFi network while plugged into an ethernet

    - by labarna
    My desk is situated at the edge of the range of a wireless signal which I use occasionally (when away from my desk) and is therefore saved in network manager. At my desk, however, I plug into the ethernet cable. While I'm working the computer is constantly trying to join the wireless network and usually failing this results in two annoying behaviors. 1: In gnome shell the network connect and disconnect notices keep popping up at the bottom of the screen and I have to click them to make them disappear (I assume it's been fixed in the next version of gnome). 2: (the worst!) Occasionally the wifi password dialog will pop up and ask for the password to this network (which is already saved). An additionally annoyance is that in gnome shell I'll get two copies of the dialog that I have to cancel, one is gnome shell themed (no window border etc...) and the other is just normal gnome themed. (Sometimes if I've been away from the computer for a while I will have multiple copies of this dialog up as its been trying to connect for a while resulting in at times 20 dialogs to cancel). Note, all the while I've been happily connected to the ethernet and have full network access. This is incredibly annoying and distracting, why doesn't ubuntu stop trying to connect to wifi if I'm on the ethernet (unless I want to broadcast my own network, but that's different)?

  • Xmonad Xsession

    - by AntLord
    My user level: noob-ish, so please bear with me I'm running 12.04 LTS. I have installed and, to some extent, configured xmonad 0.10 The "automagically" created xsession for it works fine as it is, but when I login it won't run a startup script I've created and "call from" /usr/share/xsessions/xmonad.desktop, if that's right. I've read pretty much all I could find about .xinitrc and .xsession, I tried that and it somehow messed up the other "sessions", if I'm explaining myself correctly. Had to $unity --reset to have the "main session" working again. Anyway, my question is, how do I autostart xmobar and set a desktop background after login into xmonad's default Xsession? I tried this script, start-xmonad: #!/bin/bash # #I only used one of the following each time I tried, none worked #Also, do I really need the '&'? I know what they're for, but... nitrogen --restore & feh --bg-scale ~/Pictures/picture.png & #Then I want xmobar to start, again do I need the '&'? I know it's for it to run #in the background, but I tried removing the '&' and xmonad still launched xmobar & #Finally, the only thing that seems to work in this script exec xmonad Yes, I made sure I did chomd +x ~/start-xmonad The xmonad.desktop is [Desktop Entry] Name=XMonad Encoding=UTF-8 Comment=Lightweight tiling window manager Exec=/home/myusername/start-xmonad Icon=custom_xmonad_badge.png Type=XSession So, this didn't work, now I'm here. Please help :s thanks

  • IPv6 tunnels - any easy way to turn them on and off?

    - by Rob Hoare
    I've set up a tunnelbroker.net (Hurricane Electric) IPv6 tunnel from my laptop running 12.04. Works fine, and allows me to test the dual-stack configuration on my remote webservers etc. until native IPv6 is available on my ISP. However, there are times when I don't want the tunnel. For example if I'm accessing something that requires an IPv4 address in my own country rather than the Tunnelbroker tunnel endpoint, or if I'm away from the local IPv4 tunnel endpoint, or if I simply want to test without IPv6. Is there a simple way to disable and then re-enable the IPv6 tunnel, without rebooting? For context, here's what's in my /etc/network/interfaces (NNN replaces numbers): auto he-ipv6 iface he-ipv6 inet6 v4tunnel endpoint 216.218.NNN.NNN address 2001:470:NNN:NNN::2 netmask 64 up ip -6 route add default dev he-ipv6 down ip -6 route del default dev he-ipv6 Is there a network manager application (gui or command line) to selectively enable/disable parts of /etc/network/interfaces, or IPv6 in general? I found even by commenting out that out (and reloading networking) it's tough to get the IPv6 to go away. A "tunnel on/off" button in networking would be great, like using a VPN.

  • How to remove all associated files and configuration settings of an app installed through 'force architecture' command

    - by Mysterio
    A few weeks ago I installed a 32 bit .deb file through the 'force architecture' command (on my 64bit notebook), however the procedure was unsuccessful and I used the apt-get purgecommand to uninstall the app. It seems there are some leftovers of the app I uninstalled which has now broken system update. Synaptic recommended a sudo apt-get install -fwhich I did in the terminal with this initial response: Reading package lists... Done Building dependency tree Reading state information... Done The following package was automatically installed and is no longer required: libntfs10 Use 'apt-get autoremove' to remove them. The following packages will be REMOVED: crossplatformui 0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded. 1 not fully installed or removed. After this operation, 0 B of additional disk space will be used. Do you want to continue [Y/n]? I chose 'Y' then got this response: (Reading database ... 187616 files and directories currently installed.) Removing crossplatformui ... ztemtvcdromd: no process found dpkg: error processing crossplatformui (--remove): subprocess installed post-removal script returned error exit status 1 Errors were encountered while processing: crossplatformui E: Sub-process /usr/bin/dpkg returned an error code (1) It seems the app I installed crossplatformuiis still on my system and has caused update manager to stop running with a partial upgrade warning. What do I do now?

  • Update get's stuck unpacking bad package, won't continue without it

    - by Shazzner
    Removing the package from cache, and disabling Recommended Updates in Software Sources gives me an error saying I need to install this package. I've tried to update several times, but it keeps hanging on unpacking the ubuntu-sso-client package. Which forces me to hard-reset to unlock the package manager. I've tried: sudo dpkg --configure -a No errors sudo apt-get upgrade --fix-broken Wants me to reinstall said package, resulting in it hanging Removing the package: sudo rm -f /var/cache/apt/archives/ubuntu-sso-client_1.0.8-0ubuntu1_all.deb Results in the same effect, it re-downloads then hangs I can de-select Recommended Updates but I get error messages when I try to update again: E: The package ubuntu-sso-client needs to be reinstalled, but I can't find an archive for it. Which won't let me continue Finally re-enabling the source, I try to remove ubuntu-sso sudo apt-get remove ubuntu-sso-client It removes a bunch of other packages but complains about the package: dpkg: error processing ubuntu-sso-client (--remove): Package is in a very bad inconsistent state - you should reinstall it before attempting a removal. Reinstalling ubuntu-sso-client hangs :( I'm at my wits end, any ideas? I would be nice to install all the other updates but this one is preventing it.

  • how to cout a vector of structs (that's a class member, using extraction operator)

    - by Julz
    hi, i'm trying to simply cout the elements of a vector using an overloaded extraction operator. the vector contians Point, which is just a struct containing two doubles. the vector is a private member of a class called Polygon, so heres my Point.h #ifndef POINT_H #define POINT_H #include <iostream> #include <string> #include <sstream> struct Point { double x; double y; //constructor Point() { x = 0.0; y = 0.0; } friend std::istream& operator >>(std::istream& stream, Point &p) { stream >> std::ws; stream >> p.x; stream >> p.y; return stream; } friend std::ostream& operator << (std::ostream& stream, Point &p) { stream << p.x << p.y; return stream; } }; #endif my Polygon.h #ifndef POLYGON_H #define POLYGON_H #include "Segment.h" #include <vector> class Polygon { //insertion operator needs work friend std::istream & operator >> (std::istream &inStream, Polygon &vertStr); // extraction operator friend std::ostream & operator << (std::ostream &outStream, const Polygon &vertStr); public: //Constructor Polygon(const std::vector<Point> &theVerts); //Default Constructor Polygon(); //Copy Constructor Polygon(const Polygon &polyCopy); //Accessor/Modifier methods inline std::vector<Point> getVector() const {return vertices;} //Return number of Vector elements inline int sizeOfVect() const {return vertices.size();} //add Point elements to vector inline void setVertices(const Point &theVerts){vertices.push_back (theVerts);} private: std::vector<Point> vertices; }; and Polygon.cc using namespace std; #include "Polygon.h" // Constructor Polygon::Polygon(const vector<Point> &theVerts) { vertices = theVerts; } //Default Constructor Polygon::Polygon(){} istream & operator >> (istream &inStream, Polygon::Polygon &vertStr) { inStream >> ws; inStream >> vertStr; return inStream; } // extraction operator ostream & operator << (ostream &outStream, const Polygon::Polygon &vertStr) { outStream << vertStr.vertices << endl; return outStream; } i figure my Point insertion/extraction is right, i can insert and cout using it and i figure i should be able to just...... cout << myPoly[i] << endl; in my driver? (in a loop) or even... cout << myPoly[0] << endl; without a loop? i've tried all sorts of myPoly.at[i]; myPoly.vertices[i]; etc etc also tried all veriations in my extraction function outStream << vertStr.vertices[i] << endl; within loops, etc etc. when i just create a... vector<Point> myVect; in my driver i can just... cout << myVect.at(i) << endl; no problems. tried to find an answer for days, really lost and not through lack of trying!!! thanks in advance for any help. please excuse my lack of comments and formatting also there's bits and pieces missing but i really just need an answer to this problem thanks again

  • Does Windows 7 Authenticate Cached Credentials on Startup

    - by Farray
    Problem I have a Windows domain user account that gets automatically locked-out semi-regularly. Troubleshooting Thus Far The only rule on the domain that should automatically lock an account is too many failed login attempts. I do not think anyone nefarious is trying to access my account. The problem started occurring after changing my password so I think it's a stored credential problem. Further to that, in the Event Viewer's System log I found Warnings from Security-Kerberos that says: The password stored in Credential Manager is invalid. This might be caused by the user changing the password from this computer or a different computer. To resolve this error, open Credential Manager in Control Panel, and reenter the password for the credential mydomain\myuser. I checked the Credential Manager and all it has are a few TERMSRV/servername credentials stored by Remote Desktop. I know which stored credential was incorrect, but it was stored for Remote Desktop access to a specific machine and was not being used (at least not by me) at the time of the warnings. The Security-Kerberos warning appears when the system was starting up (after a Windows Update reboot) and also appeared earlier this morning when nobody was logged into the machine. Clarification after SnOrfus answer: There was 1 set of invalid credentials that was stored for a terminal server. The rest of the credentials are known to be valid (used often & recently without issues). I logged on to the domain this morning without issue. I then ran windows update which rebooted the computer. After the restart, I couldn't log in (due to account being locked out). After unlocking & logging on to the domain, I checked Event Viewer which showed a problem with credentials after restarting. Since the only stored credentials (according to Credential Manager) are for terminal servers, why would there be a Credential problem on restart when remote desktop was not being used? Question Does anyone know if Windows 7 "randomly" checks the authentication of cached credentials?

  • Android's EditText is hidden when the virtual keyboard is shown and a SurfaceView is involved

    - by Jan
    I have a simple user interface: an EditText should be located below a SurfaceView. I use a RelativeLayout to arrange these two views. Now, when I tap on the EditText to open the virtual keyboard the SurfaceView slides up but the EditText is hidden and does not show the typed string. To reproduce, use the following layout XML code: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/RelativeLayout01" android:layout_height="fill_parent" android:layout_width="fill_parent"> <SurfaceView android:id="@+id/SurfaceView01" android:layout_width="fill_parent" android:layout_height="wrap_content"> </SurfaceView> <EditText android:id="@+id/EditText01" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentLeft="true" android:layout_alignParentBottom="true" android:selectAllOnFocus="true" android:textStyle="normal" android:singleLine="true"> </EditText> </RelativeLayout> The main Activity class only needs to show the layout. When I start the program and tap the EditText, the virtual keyboard appears but the EditText field is gone. Maybe the RelativeLayout is causing the problems, but I don't know how to reproduce the same layout with another Layout class. Any suggestions are welcome, I really appreciate your help. Thanks. Edit: Here are two screenshots, one showing the EditText at the bottom without virtual keyboard, one with virtual keyboard but with no EditText. It is interesting to note that the SurfaceView and the EditText actually shift upward, the EditText just disappears. BTW this also happens to a button if it is next to the EditText. EditText below a SurfaceView (left); EditText is gone (right)

  • How does virtual inheritance solve the diamond problem?

    - by cambr
    class A { public: void eat(){ cout<<"A";} }; class B: virtual public A { public: void eat(){ cout<<"B";} }; class C: virtual public A { public: void eat(){ cout<<"C";} }; class D: public B,C { public: void eat(){ cout<<"D";} }; int main(){ A *a = new D(); a->eat(); } I understand the diamond problem, and above piece of code does not have that problem. How exatly does virtual inheritance solve the problem? What I understand: When I say A *a = new D();, the compiler wants to know if an object of type D can be assigned to a pointer of type A, but it has two paths that it can follow, but cannot decide by itself. So, how does virtual inheritance resolve the issue (help compiler take the decision)?

  • question regarding templatization of virtual function

    - by jan
    Hi, I am new to this forum and sorry If I am repeating this question. I know that you cannot templatize the virtual function and I do understand the concept behind it. But I still need a way to get across some errors I am getting it. I am able to make my stuff work but it doesn't look to me. Here's the deal, I have class called System, #include "Vector.h" class System { virtual void VectorToLocal(Vector<T>& global_dir,const Vector<T>* global_pos = 0) const = 0; }; class UnresolvedSystem : public System { virtual void VectorToLocal(Vector<T>& global_dir,const Vector<T>* global_pos = 0) const { //do something } }; In Vector.h tenplate<typename T> class Vector { //some functions }; See now I want to templatize VectorToLocal in system.h to take just Vector, but I cannot do it as it is a virtual function. I want a work around. I know I can have VectorToLocal take Vector, Vector etc as arguments. But I do not want to do it. Any help would be really appreciated. Thanks in advance, Jan

  • IHttpModule not being applied to virtual directory

    - by arthurdent510
    I have a network folder that is mapped to my iis app as a virtual directory and I'm trying to do some authentication for files that are located there with an ihttpmodule. I've verified that the ihttpmodule is firing properly for anything else in my app, just not the files located in virtual directory. Most of what I've found is that the directory can't be listed as an application (which it isn't), and everything should work. The other solution that I found was to add the the module tag to the tag, but that didn't seem to help either. Everything that I've found talks about stopping this from happening. So my question is what could be set that is causing this to not work? Is there a certain execute permission that needs to be set? Any other iis settings that could cause this? It is an mvc app, and this is how my directory structure is laid out: server/app <- my application folder server/app/content/downloads <- downloads is the virtual directory Do I have to add the virtual directory directly under my app directory? Is that part of the problem? I don't have direct control of the server my code is running on, so testing things out is a bit of a pain... so I was looking for some more thoughts before starting to send emails off to my operations people. Thanks!

  • ASP.NET Web Application: use 1 or multiple virtual directories

    - by tster
    I am working on a (largish) internal web application which has multiple modules (security, execution, features, reports, etc.). All the pages in the app share navigation, CSS, JS, controls, etc. I want to make a single "Web Application" project, which includes all the pages for the app, then references various projects which will have the database and business logic in them. However, some of the people on the project want to have separate projects for the pages of each module. To make this more clear, this is what I'm advocating to be the projects. /WebInterface* /SecurityLib /ExecutionLib etc... And here is what they are advocating: /SecurityInterface* /SecutiryLib /ExecutionInterface* /ExecutionLib etc... *project will be published to a virtual directory of IIS Basically What I'm looking for is the advantages of both approaches. Here is what I can think of so far: Single Virtual Directory Pros Modules can share a single MasterPage Modules can share UserControls (this will be common) Links to other modules are within the same Virtual directory, and thus don't need to be fully qualified. Less chance of having incompatible module versions together. Multiple Virtual Directories Pros Can publish a new version of a single module without disrupting other modules Module is more compartmentalized. Less likely that changes will break other modules. I don't buy those arguments though. First, using load balanced servers (which we will have) we should be able to publish new versions of the project with zero downtime assuming there are no breaking database changes. Second, If something "breaks" another module, then there is either an improper dependency or the break will show up eventually in the other module, when the developers copy over the latest version of the UserControl, MasterPage or dll. As a point of reference, there are about 10 developers on the project for about 50% of their time. The initial development will be about 9 months.

  • Questions regarding detouring by modifying the virtual table

    - by Elliott Darfink
    I've been practicing detours using the same approach as Microsoft Detours (replace the first five bytes with a jmp and an address). More recently I've been reading about detouring by modifying the virtual table. I would appreciate if someone could shed some light on the subject by mentioning a few pros and cons with this method compared to the one previously mentioned! I'd also like to ask about patched vtables and objects on the stack. Consider the following situation: // Class definition struct Foo { virtual void Call(void) { std::cout << "FooCall\n"; } }; // If it's GCC, 'this' is passed as the first parameter void MyCall(Foo * object) { std::cout << "MyCall\n"; } // In some function Foo * foo = new Foo; // Allocated on the heap Foo foo2; // Created on the stack // Arguments: void ** vtable, uint offset, void * replacement PatchVTable(*reinterpret_cast<void***>(foo), 0, MyCall); // Call the methods foo->Call(); // Outputs: 'MyCall' foo2.Call(); // Outputs: 'FooCall' In this case foo->Call() would end up calling MyCall(Foo * object) whilst foo2.Call() call the original function (i.e Foo::Call(void) method). This is because the compiler will try to decide any virtual calls during compile time if possible (correct me if I'm wrong). Does that mean it does not matter if you patch the virtual table or not, as long as you use objects on the stack (not heap allocated)?

  • IIS redirect url for virtual directory

    - by Jouni
    Hello, How i can set redirect url for virtual directory in iis 7.0.I have installed lates url rewrite module 2. ? I could explain my problem with exsample. I have website on my iis 7.0 server: www.mysite.com I desided to create virtual directory sales under my site which is pointing to website root directory.Now I need create redirect url for the vdir. The vdir is pointing same virtual root directory as my site root is The big idea is that i can write on browser www.mysite/sales and i will automaticly redirect to url www.mysite.com?productid=200. I tried to make redirect with rewite url for vdir(not website), but I always get this error message : cannot add duplicate colletion entry of type 'rule' with unique key key attribute 'name' set to "test".This happens when i am pointing for virtual vdir and try to add rule. I can add rules to website level,but rules doesn work. I mean url www.mysite/sales gives me follwing error. I know that key is unique I checked it from web.config. This kind of feature was really easy use in IIS 6.0, just point vdir with your mouse and set properties--a redirect to url. Please some one explain what is right way to do it in IIS 7.0

  • Ubuntu won't suspend automatically any more

    - by Sparhawk
    In the last month or so, Ubuntu (12.04) has stopped sleeping automatically. I've gone to System Settings Power, and verified (and toggled) "suspend on inactive for" to 5 minutes (for both battery and "when plugged in"), but the system stays awake. I've also tried used code similar to $ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 300 $ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout 300 to set the timeout values. I've also verified these in dconf Editor. Previously, I could set this quite low to make my computer sleep quickly, but now it no longer works either. I'm not sure if this is relevant, but under old versions of Ubuntu, if I wanted my computer to never suspend (via the CLI), I would also have to set $ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac false At some point, this seemed to have been depreciated (and also gave me the error "No such key 'sleep-inactive-ac'"). I found that it it was enough to set sleep-inactive-ac-timeout to 0. This worked for a while, but at some point auto-suspend stopped working as stated above. Oddly enough, the sleep-inactive-ac key is still present when I look via dconf editor. However, when I click it, it says "no schema", and the summary, etc. fields are blank. To test if the dconf power plugin was working, I tried playing around with other settings in the schema. Idle-dim-time and idle-dim-ac work as expected . However, setting sleep-display-ac to 5 seconds has no effect. I'm also not sure if this is relevant, but I've uninstalled gnome-screensaver, and installed xscreensaver. I have tried killing xscreensaver and re-installing gnome-screensaver, but this did not help. I've also had some trouble with DPMS. I'm not sure if this is related, but I'll put the information here, just in case. Using xscreensaver, I set Power Management to enabled, with standby and suspend timeouts to 10 minutes. I've verified these settings in ~/.xscreensaver and xset q. However, the screen blanks after about 30 seconds. If I turn off DPMS (either via xscreensaver GUI or modifying ~/.xscreensaver), it won't blank at all, so I know that DPMS is partially reading the xscreensaver settings. -- edit I've attempted more troubleshooting, by creating a new user account, then logging out of the main account and into the new account. I've tried modifying the timeouts via dconf, but get the same results as above (i.e. it doesn't work, nor does sleep-display-ac, but idle-dim-time and idle-dim-ac work). Also, the depreciated sleep-display-ac key is not visible, so I think that this is probably unrelated. -- edit I've since moved to gnome-shell instead of unity, and still have this problem, so I guess that it's something to do with gnome-power-manager.

  • What can a Service do on Windows?

    - by Akemi Iwaya
    If you open up Task Manager or Process Explorer on your system, you will see many services running. But how much of an impact can a service have on your system, especially if it is ‘corrupted’ by malware? Today’s SuperUser Q&A post has the answers to a curious reader’s questions. Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader Forivin wants to know how much impact a service can have on a Windows system, especially if it is ‘corrupted’ by malware: What kind malware/spyware could someone put into a service that does not have its own process on Windows? I mean services that use svchost.exe for example, like this: Could a service spy on my keyboard input? Take screenshots? Send and/or receive data over the internet? Infect other processes or files? Delete files? Kill processes? How much impact could a service have on a Windows installation? Are there any limits to what a malware ‘corrupted’ service could do? The Answer SuperUser contributor Keltari has the answer for us: What is a service? A service is an application, no more, no less. The advantage is that a service can run without a user session. This allows things like databases, backups, the ability to login, etc. to run when needed and without a user logged in. What is svchost? According to Microsoft: “svchost.exe is a generic host process name for services that run from dynamic-link libraries”. Could we have that in English please? Some time ago, Microsoft started moving all of the functionality from internal Windows services into .dll files instead of .exe files. From a programming perspective, this makes more sense for reusability…but the problem is that you can not launch a .dll file directly from Windows, it has to be loaded up from a running executable (exe). Thus the svchost.exe process was born. So, essentially a service which uses svchost is just calling a .dll and can do pretty much anything with the right credentials and/or permissions. If I remember correctly, there are viruses and other malware that do hide behind the svchost process, or name the executable svchost.exe to avoid detection. Have something to add to the explanation? Sound off in the comments. Want to read more answers from other tech-savvy Stack Exchange users? Check out the full discussion thread here.

  • Ping bind errors in Operations Manager 2007

    - by Andrew Rice
    I am having an issue in SCOM 2007 R2. I am routinely getting the following errors: Failed to ping or bind to the RID Master FSMO role holder. The default gateway is not pingable. Failed to ping or bind to the Infrastructure Master FSMO role holder. The default gateway is not pingable. Failed to ping or bind to the Domain Naming Master FSMO role holder. The default gateway is not pingable. Failed to ping of bind to the Schema Master FSMO role holder. The default gateway is not pingable. The weird thing about these errors if I log into the server in question or if I log in to the SCOM server I can ping everything just fine. To top it all off the server in question is the role holder for 2 of the roles it is complaining about (RID and Infrastructure). Any thoughts as to what might be going on?

  • How to rearm Microsoft Office in 2010 Information Worker Demonstration and Evaluation Virtual Machine (SP1)

    - by John Assymptoth
    I'm doing some tests in a 2010 Information Worker Demonstration and Evaluation Virtual Machine (SP1). However, after a few days (maybe ~180), Office is now saying that it needs to be activated. I've tried rearming with OSPPREARM.EXE, but I get the following error: "The security processor reported that the maximum allowed number of re-arms has been exceeded. You must re-install the OS before trying to re-arm again." How can I circumvent this, without losing all the data I have in the VM?

  • Active Directory and Apple's Workgroup Manager

    - by qbn
    I thought I'd share my experiences here. I work for a small business with only ~20 users. I wanted the ability to use managed client preferences to assign things like the software update server. Basically the ability to manage my Macs easily and in a native way. At first I tried the magic triangle solution, but I found this to be very complicated. Not only does it require a Mac OS X Server, but it gives you two points of failure. Additionally each Mac workstation must be bound to both servers. Eventually I sucked it up and went with the schema changes documented here. I was hesitant at first, because the instructions require a lot of manual work. However it was fairly basic and only took me about an hour and a half. Below you'll find the schema changes file that was a result of my work. I followed the instructions exactly and double checked everything, after six months of having this in place things have been running great. Too good to not share. I hope I save someone a couple of hours. # ================================================================== # # This file should be imported with the following command: # ldifde -i -u -f Apple AD Schema Changes.ldf -s server:port -b username domain password -j . -c "cn=Configuration,dc=X" #configurationNamingContext # LDIFDE.EXE from AD/AM V1.0 or above must be used. # This LDIF file should be imported into AD or AD/AM.

  • Partitioning recommendations for a Proxmox VM Server (OpenVZ)

    - by luison
    We are new to virtualization and we are planning to turn our online server into a virualized one, mainly for maintenance, backup and recovery improvements. Initially we would only have one real virtual system with load plus 1-3 copys for testing and recovering and maybe a small centralized syslog virtual machine. We would like, if possible the host machine to include an iptables plus rsync to back up to other machines and some other global security systems. Due to this and the offerings of our hosting supplier we are mainly considering Proxmox for its simplicity (we like the idea of its web admin panel) and as I also understand that the container approach of OpenVMZ systems may fit well resource wise with our setup. The base system comes with debian so we can personalise it to our requirements. Proxmox installations default installs an LVM partition for the VMs. Our doubts are with the fact of what would be the best partition structure for this considering that: we would like to have a mirror of the root partition we could boot from if required (our provider supports booting the system from another partition via control panel) we ideally would like to have a partition that could be shared among the VM systems. We still don't know if this is possible directly with OpenVMZ containers, otherwise we are considering doing this by sharing it via NFS on the host machine. we want to use the backup system available on the proxmox host administrator to programme VMs backups and then rsync it to another machine. With this based on a Linux Raid of aprox (750Gb) we are considering something like: ext3_1/ - (20Gb) ext3_2/bak_root - (20Gb) mostly unmounted, root partition sync LVM_1 /var/lib/vz - (390Gb) partition for virtual images LVM_2 /shared_data - (30Gb) LVM_3 /backups - (300Gb) where all backups would be allocated Our initial tests with Proxmox seem to have issues with snapshots backups like this, perhaps caused by the fact that they can not be done to another LVM partition (error: command 'lvcreate --size 1024M --snapshot --name vzsnap-ns204084.XXX.net-0 /dev/pve/LV' failed with exit code 5) in which case we might have to use a standart ext3 partition (but unsure if we can do this with the 4 primary partition limitations). Does this makes more or less sense? Would it be mad to for example write VMs /var/logs to a NFS mounted partition (on the host system)? Are their any other easier ways to mount host system partitions (or folders) to the VMs?
