The file to update is :

%USERPROFILE%\Application Data\VMware\config.ini

for windows versions of VMware workstation, and :

~/.vmware/config

for Linux one.

The parameter you have to add is :

mks.noBeep = “TRUE”

Please note:

• The configuration file is “profile” dependent; so if you update it for your profile, other ones in the same computer won’t have it configured.
• You have to stop/close all Vmware Workstation running instances.
• You may need to restart the “VMware Autorization Service“
• You may not find the config or config.ini files, so just edit a new file.
• Under Linux, a file or folder for which the name starts with a Dot is hidden, to be able to see it you have to issue an “ls -a” to display it.

Hope this was helpful.

We saw in a previous article how to save and restore a Windows 2003 system by using ASR. This is a particular method available in Windows 2003 but not in Windows 2000 and older versions.

Based on a live linux 22Mb image, PING offers all needed commands to map a Windows share, mount an NFS partition, and maybe make an FTP image. The included automated dhcp client makes it easy for people not used to linux systems to use PING without any problem.

In the officiel Website we can read more details about its advantages; those I find interesting :

• Backup and Restore the BIOS data as well;
• Either burn a bootable CD / DVD, either integrate within a PXE / RIS environment;
• Possibility to Blank local admin’s password;
• Create your own restoration bootable DVD

and if we compare PING to DOS or Ghost tools :

• Most network cards automatically recognized by the Kernel;
• Most CD/DVD readers automatically recognized by the Kernel;
• You don’t have to run a Ghostcast server to receive images over the network;
• More supported filesystems;
• You can store an image on several CD/DVD (CD/DVD-spanning);
• You can backup and restore BIOS settings too;
• Much much smaller than WinPE / BartPE;

Basic linux commands are also available to run in the text mode. In fact, PING starts a text based assistant to guide the user step by step. It is always possible, if the assistant exits, to start it by using

/etc/init.d/rc.ping

script.

In the example I expose in this video, I start by making an image of a Windows 2003 server to a network share. Then I destroy the existant disk and create a new blank one. Then I restore the saved image to the new disk. Note that source and destination disks may be of different sizes, but necessary the source larger than the destination.

An evident remark is that the tool may be used for any kind of operating system, as it does not look at files level but in blocs one.

Enjoy seeing this video, and I hope it will help!

The Service Console is a modified version of Red Hat Linux which is used to boot and load the VMkernel for VMware ESX Server and provide services such as the Apache web server for the MUI and command-line management. It has several commands that are unique to ESX Server such as vmware-cmd, vmkfstools, vmkpcidivy, esxtop, and some custom scripts.

To attach to the Service Console remotely from a Windows workstation, you can use the PuTTY SSH client, freely available from its official website.

Practical Examples

• If you need to view current partitions, sizes, and the amount of disk space consumed, type :

vdf –h

the output should be similar to the one showed bellow

View consumed disk space on esx host

• If you want to view the contents of a VMFS volume on your server, type :

vmkfstools –l vmfs_label

• To check disk space consumption under a specific directory, type :

du –sk directory-name

• To find out which device file maps to a LUN,

1. type : vmkpcidivy –refreshnames (This refreshes the table of device files.)
2. type : vmkpcidivy –q vmhba_devs

• To export a virtual disk from vmfs to a different location on your ESX Server, type :

vmkfstools –e /targetdirectory/filename.vmdk /vmfs/volume_label/sourcefile.vmdk

• To display all registered VMs, type :

vmware-cmd –l

List Registred virtual machine on esx host

• To power on VMs from the Service Console, type :

vmware-cmd vmx-configfile start soft

• To power off VMs from the Service Console, type :

vmware-cmd vmx-configfile stop soft

or

vmware-cmd vmx-configfile stop hard

I’m trying here to list some available commands and their options, but it is not intended to replace the officiel documentation neither a better reference.

Using esxcfg

In addition to the standard Linux commands, VMware has implemented a specific set of commands directed toward ESX-specific tasks. The following list of commands show how to manage various components of the ESX Server configuration.

esxcfg-auth Used to configure an ESX Server host to support network-based authentication methods (e.g., Active Directory [AD]).

• - -enablead to configure Service Console for AD authentication
• - -addomain to set the domain the Service Console will authenticate against
• - -addc to set the domain controller to authenticate against for AD authentication
• - -usecrack to enable the pam_cracklib for managing password complexity

esxcfg-firewall Used to query, enable, and disable services on the Service Console firewall. Note that everything is blocked by default.

• -q to query the current firewall settings
• -q servicename to query the status of a specific service
• -q incoming/outgoing to query the status of incoming and outgoing ports
• - -blockIncoming to block all incoming connections on ports not required for system function
• - -blockOutgoing to block all outgoing connections on ports not required for system function
• - -allowIncoming to allow incoming connections on all ports
• - -allowOutgoing to allow outgoing connections on all ports
• - -e servicename to enable a specific service
• - -d servicename to disable a specific service

esxcfg-info Used to review the hardware information for Service Console and VMKernel.

• -w to print hardware information
• -s to print storage and disk information
• -n to print network information

esxcfg-mpath Used to view and configure the multipathing settings for an ESX Server host’s fibre channel or iSCSI storage devices. Multipathing is the ability to connect to SAN or iSCSI storage devices through multiple pahs, and it suppose that the host has at least (and it is enough) 2 HBA cards.

• -p to set the policy for mru (most recently used), fixed, or rr (round-robin)
• -P to define a path to operate on
• -s with “on” or “off” to enable or disale a specific path
• -f to set a specified path as the preferred

esxcfg-nas Used to configure NAS storage on ESX Server. NAS is supported by ESX but limits its features like vMotion which is not allowed in this case (but still it is a low cost solution)

• -l to list all NAS
• -a to add a new NAS datastore on a specified host
• -o to provide the name of the NAS host
• -s to provide the name of the NAS share
• -delete to delete a NAS datastore

esxcfg-nics Used to obtain information about and configure the physical network adapters installed in an ESX Server host.

• -s to set the speed of a card to 10,100,1000, or 10,000.
• -d to set the duplex to half or full

esxcfg-route Used to configure the default gateway for the VMkernel.

esxcfg-swiscsi Used to configure the software iSCSI component of ESX Server.

• -e to enable software iSCSI
• -d to disable software iSCSI
• -q to query if software iSCSI is enabled
• -s to scan for new LUNs using software iSCSI

esxcfg-vmhbadevs Used to obtain information about the LUNs available to the ESX Server.

• -m to print the VMFS UUID if formatted as VMFS esxcfg-vmknic Used to configure the VMkernel NIC.

• -D to disable the VMkernel port
• -i to set the IP address of the VMkernel NIC
• -n to set the network mask for the IP of the call

esxcfg-vswif Used to set the parameters of the Service Console; the Service Console interface allow management of the ESX.

• -a to add a Service Console NIC (this option is predicated on having IP information and port group names)

• -D to disable the Service Console NIC
• -p to set the port group name for the Service Console NIC
• -i to set the IP address to be used for the Service Console NIC
• -n to set the network mask of for the Service Console NIC

esxcfg-vswitch Used to add, remove, or modify a virtual switch. All network communications of virtual machines go through virtual switches.

• -a to add a new virtual switch
• -d to delete a new virtual switch
• -l to list all existing virtual switches
• -L to unlink a network adapter from a hosting provider
• -U to link a network adapter
• -v to set the vLAN ID for a port group
• -A to add a new port group
• -D to delete a port group
• -C to query for the existence of a port group name

Using vicfg

The latest updates to the VI3 product suite, ESX Server 3.5, ESXi, and VirtualCenter 2.5 have also brought about the introduction of a new set of command line tools in the vicfg. The commands are similar to the esxcfg commands but are more directly dedicated to remote host management functions using the new remote command line interface tool available from VMware.

Just to remid you, ESX 3.5i comes without the “management virtual machine” that everybody takes for the OS of the ESX! In fact, the ESX 3.5i is a 32Mb OS, in other words, the least set of commands to manage VMs.

Hope this helps!

La solution est plutôt simple à mettre en place mais il faut la connaitre! Il s’agit d’ajouter un paramètre de timeout ou de délai entre caractères saisis. Il faut définir ce paramètre pour toutes les machines virtuelles (Windows, Linux, ou autre) qui posent ce problème.

Il s’agit du paramètre:

typematicMinDelay

Il faut ouvrir le fichier de configuration de votre machine virtuelle (le fichier .vmx dans le dossier de la VM), et ajouter, à la dernière ligne, l’entrée suivante:

keyboard.typematicMinDelay = 2000000

Le chiffre 2000000 determine la durée entre deux saisies successives, on la force à 2 secondes dans notre cas (vu que l’unité par défaut est la µSec).

Voilà! il faut démarrer/redémarrer votre machine pour que la modification soit prise en compte.

Hope this helps!

Les keymaps

Les keymaps sont les cartes qui permettent le mappage d’un carractère à une touche ou une combinaison de touches du clavier. Il en va que si on utilise une carte anglaise chez les français on ne trouvera pas facilement notre chemin n’est ce pas?! Sous linux, les keymaps sont des fichiers “.maps.gz“, donc pensez à chercher ces fichiers si vous travaillez sur une distribution qui n’utilise pas les mêmes chemins pour ses fichiers système. Pour la famille Redhat (et donc Fedora) les fichiers, nottament pour le clavier azerty sont stockés dans le chemin:

/lib/kbd/keymaps/i386/azerty

Le fichier maps utilisé par le système est défini par la clé : KEYTABLE du fichier :

/etc/sysconfig/keyboard

Comment changer les keymaps sous Linux Redhat

Maintenant que nous avons bien saisi comment ça marche, ci-dessous la procédure de changement du clavier étape par étape:

1. Lister le contenu du dossier  /lib/kbd/keymaps/i386/azerty pour localiser le fichier maps à utiliser.
2. Repérer les fichier maps qui commencent par : fr*, nous nous intéresserons au fichier fr-latin1.maps.gz
3. Éditer le fichier /etc/sysconfig/keyboard
4. Changer la valeur de la clé KEYTABLE de us par exemple à fr-latin1, sauvegarder.
5. En l’abscence d’un fichier script pour le clavier sous /etc/init.d/, il faudra redémarrer votre linux pour que le changement soit pris en compte.

Pour résumer ce qu’on a vu, la vidéo ci-dessous reprend toute l’opération.

J’espère que cet article vous a été utile. Bonne lecture sur ntsysv.com!

L’utilisation journalière des systèmes Windows (2000, XP ou autres) nous laisse face à certaines limites dans ce sens. Certes les possibilités de programmations sous Windows sont aussi importantes et évoluées mais certainement plus difficiles à appréhender. En effet, Windows permet l’utilisation de VB Script, JScript, WSH, …etc, mais il faut une certaine maitrise de ces outils avant de pouvoir en tirer grand bénéfice. Le traitement des fichiers logs par exemple est assez difficile et  les outils comme sed, awk, cut …etc.nous manquent.
Cygwin, l’une des solutions qui ont démontré leur utilité et efficacité. Microsoft offre SFU, Services For Unix , qui permet d’aller plus loin dans l’intégration des services et produits Unix sur les systèmes Windows serveur. Cygwin est libre d’utilisation, et est téléchargeable sur http://www.cygwin.com/ .
Nous allons voir dans ce qui suit comment installer cygwin, et comment utiliser son environnement pour l’écriture de scripts shell.

Installation de Cygwin

Cette vidéo montre les étapes à suivre pour installer cygwin. Enfait, sur le site il faut télécharger le fichier setup.exe qui gère le téléchargement des binaires nécessaires.

une fois l’installation terminée, l’arborescence comparable à tous les systèmes Linux est créée sous le dossier de l’installation (par défaut c:\cygwin) et qui est assimilé à la racine linux comme illustré dans la figure ci-dessous.

Arborescence Cygwin

Lancer cygwin à partir de l’icône du le bureau revient à lancer le fichier batch Cygwin.bat. Nous allons maintenant écrire un script témoins comme le veut la tradition : hello world!

Écriture de script

Il y a une infinité de possibilités d’écriture de scripts. Cygwin intègre par défaut les outils standards comme sed et Awk. Perl et Python doivent être explicitement ajoutés à la liste des binaires à installer.

Le script est simple : Afficher la chaine de caractères : “Hello Cygwin World” avec le bout de code suivant:

#!/bin/bash

echo “Hello Cygwin World!”

exit 0

La vidéo résume l’opération en question.

Ainsi nous avons accès à toute la facilité du scripting Linux sous Windows.

Vous pouvez retrouver plus de détails sur l’installation de Cygwin, et son confrère CygwinX sur le site de lip6.

Dans le prochain article, je vais vous présenter l’installation de Honeyd sous Windows en me basant sur Cygwin.

Bonne lecture!
