Ubuntu Netbook Edition How To Connect Mount Windows Shares

I would say that Canonical/Ubuntu coders staff forgot something in the Ubuntu Netbook Edition I see this in 10.04.

They forgot the Places, one place really familiar to Ubuntu users where to find the habitual way to connect to a windows server.

Well, to connect and mount a windows share, one additional step is needed.

This is How To Connect to a Windows Share with Ubuntu Netbook Edition
you go to your home folder in "Files and Folders" (File e cartelle) and you open it, it is the one with your user name.

When it has open, you can open the File menu and choose the Connect to server... or you can go to the left panel where you'll find the network icon that will allow you to browse the windows network.

When have got your share connected (this will either mount it) you can also bookmark it from the Bookmarks menu (menu Preferiti).

There is a way to got the share mounted automatically at every boot, but it is not the goal of this thread.

If this saved you some time, please drop aline in the comments.

See you

Ubuntu 10.04 condivisione dei files personali

Tags: Non è possibile abilitare la condivisione dei files, Come abilitare la condivisione dei files sul network, La condivisione dei files è disabilitata

Pare che in casa ubuntu si siano dimenticati un pezzo dell'installazione.

Infatti, ancora oggi, il fenomeno non è stato corretto (ma forse è voluto così?) e non è quindi possibile abilitare il files sharing dal menu Sistema - Preferenze - Condivisione dei files personali

Niente di trascendentale, ecco come

Windows VM guest How To Install XenServer Tools ( Citrix Tools for Virtual Machines )

When I was a poor newbie with XenServer (until yesterday :-) ), I had to search a lot to find the instructions on how to install xen-tools for xenserver ;-P

The main error was searching for xentools or xen-tools, that is not the correct name for Citrix XenServer.
The correct one is Citrix Tools for Virtual Machines, what they at Citrix call
The Citrix paravirtualized network and SCSI drivers (Citrix Tools for Virtual Machines)

If you experience XenServer poor performances in Windows VM guests disk write speed or network file transfer speed, you'd better read the full story about how to install and purposes of
Citrix Tools for Virtual Machines formerly PV (paravirtualized) device drivers
(click the link to read official documentation from Citrix)

Please note that official documentation says:

Running Windows VMs without these drivers is not supported.

Please also note that official documentation says:

Warning:
Before updating Windows operating systems you must uninstall the PV device drivers. If they are present during the attempt to update, the update will fail.

xenserver xe sr-create error The SR operation cannot be performed because a device underlying the SR is in use by the host

This error looks to me to come mainly from the xenserver SR database.

If entering command like

xe sr-create shared=true device-config:device="/dev/drbd1" name-label="DRBD-SR1" type=lvm

exits and returns

The SR operation cannot be performed because a device underlying the SR is in use by the host.

you'd better verify that drbd1 is not already part of the xenserver SR database and if the case, remove it (obviously if you really deleted it in your drbd experimentations)

That is the clean solution... otherwise I'm quite sure (not tested) that choosing a different device name, would work like a charm but this would make not much sense.

Please note that playing with drbd may result in such situation where you already used any drbd resource name to provide some SR to xenserver and next, you forget it...

XenServer 5.6 How To Backup VMs on a windows share

To Backup one XenServer VMs on a windows share, first we need to mount the windows share on the XenServer.

This is done at XenServer command line interface level.
Ssh connect to XenServer and create the needed directory (I call it backup)

[root@XenServer /]#mkdir /backup

next step is to mount the windows share (windows machine is 192.168.0.200 and the share name is ttm) in the brand new backup directory:

[root@XenServer /]#mount -t cifs //192.168.0.200/ttm -o username=user,password=password /backup

be sure that your windows box ip address matches and please note that cifs requires slashes and not backslashes, so the correct symbol is '/'

If everything went ok, we should be able to verify the mounted share:

[root@XenServer /]#mount | grep backup
//192.168.0.200/ttm on /backup cifs (rw,mand)

We are now ready to export VMs on a windows share.
This is done by the following command

[root@XenServer /]#xe vm-export vm=vmname filename=/backup/vmname.xva

WARNING! - If you did it via ssh, DO NOT close the ssh terminal, 'cause this would stop the export process

after the process is started nothing happen on the xenserver console, but if you check the windows directory the .xva file should be present and groving

when export process succeed the following message is printed

[root@XenServer /]#Export succeeded

Blogspot, i commenti spariscono e non si pubblicano

ATTENZIONE! A tutti i blogger, i commenti di blogspot funzionano male.

Sono incappato in una strana problematica: non riesco a scrivere commenti su quasi nessun blog di blogspot.

Compilo tutti i campi ma alla fine, neanche l'anteprima funziona e cliccando pubblica o anteprima tutto il testo sparisce.

Quel che è peggio è che non potevo scrivere i commenti neanche in questo mio stesso blog... eh no!! A tutto c'è un limite e allora mi sono impuntato.

La soluzione è stata di modificare le impostazioni del blog nella sezione dei commenti e impostare il modulo "a pagina intera"

Se volete garantirvi il massimo dei commenti, è meglio che cambiate il settaggio suddetto, altrimenti i poveri lettori vi manderanno a quel paese.

Infatti non funziona nessuno dei metodi, account google, anonimo, nome utente e url etc etc.

Ciao e se vi è stato utile... scrivetemi un feedback... ora finalmente i commenti funzionano correttamente.

Nota: Io uso firefox e lo aggiorno continuamente. Non ho neanche provato con altri browser, non mi importa. Concettualmente se un utente firefox non può commentare nel mio blog, questo è un gravissimo problema ed una gravissima limitazione.

Outlook 2007 Postfix error 0x800CCC80

On many of my customers I've got a Fax Server made with Hylafax.

Faxes traffic is notified by email and because of this postfix is installed without too much security, the reason of this is that emails are sent only locally: no internet access for the Fax Server.

Well, today they introduced Outlook 2007 in one client and mails from that outlook 2007 client are not sent anymore with error 0x800CCC80.

How to fix this? After some checks I noticed

A python multiplatform alternative to Citrix XenCenter: OpenXenManager

Author of OpenXenManager aka OpenXenCenter says the project has born because of the non sense to have a virtualization system based on linux that graphically can only be managed from windows O_o!?

Why not to have a linux graphical manager for xenserver?

From here you reach the project page
http://www.openxenmanager.com/

download it and run it by python engine

Here you can find the python engine, useful for both windows, linux, osx and so on users
http://www.python.org/download/

This is an official tutorial for the OpenXenManager windows version installation
