Montar ftp como unidad en Windows

Killer{R}, a Russian guy has developed a very good alternative: FTP Drive is freeware and available for download, and it offers a quick way to emulate a network folder for your FTP connections. It installs a virtual drive in “My Computer”, with a letter of your choice, in which it puts a folder for every your FTP account.
Now you can load and save on FTP exactly as you usually work on your local files.



Configuration is not harder than a traditional FTP client: FTP Drive stays in the systray and it requires not much RAM just (3-4Mb).
Just click FTP Drive settings and then “Edit server list manually” (it can also automatically retrieve FTP accounts from Netview, a freeware TCP Manager by Killer{R}); type the address of your FTP server, you login and password and some additionaly option, like the preferred transfer mode and the threads limit. Then click the add button and you’re ready to go: a new folder will appair in “My computer”, under FTP Drive’s network folder, and you”ll be able to operate directly on remote files.

Applications are unlimited: you can load a PHP page into your editor, change something and save directly from it to have the online page immediately updated, or you can save a picture found on the Internet from Firefox directly to an FTP drive to have uploaded it on your web server and immediately available for your visitors.

Como instalar XP desde un USB

1) Formatted the USB flash drive with HP's utility, using Windows Enabler to make it bootable with DOS.
2) Slipstreamed an XP Pro CD using NLlite to include SP2 and the Intel Matrix Storage Manager (the SATA drivers)
3) Copied the slipstreamed i386 directory onto _both_ the USB flash drive, and the destination hard drive from the X61 (hooked up via external USB enclosure)
4) Copied smartdrv.exe, himem.sys and config.sys (enabling himem) from a Win98 boot disk onto the USB drive.
5) Boot the X61 from USB (Access IBM - F12 - select the appropriate USB drive), launch smartdrv, then launch winnt from the i386 directory.

At this point the install ran more or less normally. The one caveat is that you need to have the i386 directory on the internal drive too, because when XP is finally bootstrapping itself from the internal drive, it may not have access to the USB flash drive (as in my case).

Configurar NFS Server en Windows

Using Windows-based NFS in VI3

Jason Mattox from vizioncore has provided the following information for people looking to use some of the low-cost storage alternatives available in VI3. This particular setup uses a Windows machine and Windows Services for UNIX to create an NFS share that can be mounted to an ESX host for Virtual Machine, Template or ISO storage. I will follow this article up shortly with a free software iSCSI setup that runs extremely well for lab/test usage. The following URL also has a detailed description of NFS Authentication when using WSFU and was utilized to create this quick-start guide:http://www.microsoft.com/technet/interopmigration/unix/sfu/nfsauth.mspx

The main steps in this process are:

1. Installing Windows Services for UNIX (WSFU)

2. Copying the ESX Server password and group files to Windows

3. Configuring WSFU for accepting ESX Server connections

4. Sharing the Windows folder for NFS compatibility

5. Configuring the ESX Server to mount the Window NFS Share as Datastore.


1. Installing Windows Services for UNIX (WSFU)

Download windows services for UNIX at:
http://www.microsoft.com/windowsserversystem/sfu/downloads/default.mspx

Install WSFU on the desired machine
Add in the following options
NFS + Server for NFS
Authentication tools for NFS + user name mapping
After installation, open services control panel applet and change the service ‘User Name Mapping’ to startup automatically and then start the service

2. Copy the ESX Server password and group files to Windows

Use a program like WinSCP or similar process to copy the following files to your local system where WSFU is installed
You can get WinSCP from the fowling location.
http://winscp.net/eng/download.php#download2
Transfer the file /ect/password and the file /ect/group to C:\SFU or to the location where you installed WSFU

3. Configure WSFU to accepting ESX Server connections

Click Start, Programs, Windows Services for UNIX, Services for UNIX Administration
Go to user name mappings then configuration
Click password and group files
Then browse for the password and group files that you copied, from the browse dialog box for both the password and group fields
Click apply
Then go to maps
Click show maps
List windows users and list Unix users
Then select a local administrator user on the left that will be mapped to the root account and the root user on the right.
Then click apply (upper right)
My path is \\myserver.mydomain.int\NFS-VMFS01 for the windows share and NFS share on the windows host with WSU installed.

4. Sharing the Windows folder for NFS compatibility

Right click the local folder you wish to share via NFS
Share the folder by clicking NFS sharing
Type in the name for the share i.e. NFS-VMFS01
Remove allow anonymous access
Click permissions
Now Change type of access to “Read+Write” then check allow root access.

5. Configure the ESX Server to mount the Window NFS Share as VMFS

Open the VC client and highlight the Vi3 host
In the Configure tab choose Networking
Add networking, VMKernel then pick a vSwitch, then give the VMkernel an IP that is accessible via the NFS host.
Now open the storage option for this host
Click add storage, > Network File System
In the Server Field enter in myserver.mydomain.int
In the Folder field enter /NFS-VMFS01
For the Datastore I also used NFS-VMFS01
