Enough babbling, on with the geeking.

Here’s the basic problem/challenge. While in an ideal situation, SFTP Drive looks nice, in reality, I’ve had problems with it during my 6 week trial that left me waiting till they work out some of the kinks. Most notably were the errors in connecting to this site after some sort of timeout. In those cases, I was entirely unable to connect to the site (even with disconnecting and reconnecting the SFTP Drive) without rebooting. Sorry, but that doesn’t fly.

However, I still would really like easy access to my remote machines’ files and preferably via SSH. So, since I had seen evidence of sshfs on Linux working at least on that end, I messed with that for a couple of days and finally got one of my virtual Ubuntu VMWare appliances to connect to Wynia.org via sshfs.

Then, yesterday morning a though occurred to me. What if I connected to the remote machines via sshfs on one of the Ubuntu machines and then shared the mounted directories via Samba. That way, I’d be able to map drives to these remote servers on my Windows workstations. I’d have *mapped drives to SFTP locations* by just going through a virtual Linux machine.

I went digging before work and got most of it working and finished the rest (though I do have a wishlist at the end for missing features) last night. It works. What follows is what needs to happen to make it work.

I started with an Ubuntu Server installation on VMWare Server, logged in as my one regular user. The virtual machine in question is my web development machine (mostly LAMP setup). SSH was already installed and working.

To install the sshfs package on the virtual machine:

sudo apt-get install sshfs

In order to be able to use the mounted directory as a regular user, you need to be added to the “fuse” group, which the package created:

sudo adduser your-username fuse

Note that the permissions change doesn’t actually work until you log off and back on. However, since a reboot is needed shortly, don’t worry about it.

Then, you need to create a directory for the remote mounted machine:

sudo mkdir /mnt/wyniaorg

sudo chown your-username /mnt/wyniaorg

Now, here’s the part that wasn’t in most of the tutorials, but necessary to make Samba work later on.

Create a file at /etc/fuse.conf

touch /etc/fuse.conf

Put the following line in /etc/fuse.conf:

user_allow_other

REBOOT

To mount the remote directory, here’s the command that I use for Wynia.org:

sshfs wynia@wynia.org@84.40.22.116:/var/www/html /mnt/wyniaorg -o allow_other

Note that I actually need to use a full email address to log in to this server, so the first “@” is part of the username and the second is the delimiter for the host. The “/var/www/html is the remote directory and “/mnt/wyniaorg” is the local directory on the virtual machine.

It’ll ask you for your password. For the moment, I’m going to have to type that in every time I mount the remote drive. There’s a potential solution out there, but it doesn’t work for the server this site sits on.

To avoid having to retype that beast of a commandline repeatedly, I saved the command as

~/scripts/sshfs_wyniaOrg.sh

Then make it executable:

chmod +x ~/scripts/sshfs_wyniaOrg.sh

To run that script:

cd ~/scripts

./sshfs_wyniaOrg.sh

I also created a script to unmount the directory:

fusermount -u /mnt/wyniaorg

and put it as “un_sshfs_wyniaOrg.sh”, also making it executable.

To install Samba:

sudo apt-get install samba smbfs

To share the mounted drive, you need to edit the Samba config file:

sudo pico /etc/samba/smb.conf

I wanted to not have to enter a password to access the shared drive, so in /etc/samba/smb.conf, I set the security to

security = share

and then added a section at the end of the file for my new share.

[wyniaorg]

comment = wyniaOrg

path = /mnt/wyniaorg/

public = yes

writable = yes

create mask = 0777

directory mask = 0777

force user = nobody

force group = nogroup

I also added a section to share the /var/www directory of the virtual appliance itself:

[public]

comment = PHP Dev Server WWW

path = /var/www/

public = yes

writable = yes

create mask = 0777

directory mask = 0777

force user = nobody

force group = nogrou

Then, to open the files, I’ve already got the IP address in my hosts file (C:\WINDOWS\system32\drivers\etc\hosts):

192.168.252.171 php

So, in Windows Explorer, I can just:

\\php\

and I see my remote directory and the public share right there in Windows.

If the remote directory isn’t mounted, you just get an empty directory. This is good because, as long as the Linux/Samba portion is up and running, Windows will map to the directory without complaining: there just won’t be anything in there. This is good fallback behavior and beats the heck out of what Windows does when it can’t find the network share at all. All that freaking out with warning dialog after warning dialog drives me nuts.

If you want to make the mapping of the drive semi-automatic, you can create a Powershell (more on this amazing addition to Windows in a couple of days) script called something like “map_wyniaorg.ps1″ containing this code:

cls

$Drive = “J:”

$UNC = “\\php\wyniaorg”

# Create the Com object with New-Object -com

$net = New-Object -com WScript.Network;

# $net.removenetworkdrive($Drive)

$net.mapnetworkdrive($Drive,$Unc)

# Launches the Explorer

$shell = new-object -comObject Shell.Application

$Shell.open($Drive)

While I’ve gotten ssh without a password to work *between* the Ubuntu VMWare servers I’ve set up (using the instructions all over the web), I haven’t gotten it to work with the wynia.org ssh setup. So, for now, I just deal with the password thing.

If the lazy web wants to grant my wishes, what I still want is the easy way to:

1. Do the sshfs mounting automatically.

2. Without passwords.

3. Without logging on to the machine.

4. At bootup.

5. And to make sure that cleanup is done properly at shutdown.

Oh, and I probably missed something, which will become clear the next time I want to do this on a machine and come back to this article. However, if you have a problem, let me know and I’ll update.

(singing)
We belong together
And you know that I am right
Why do you play with my heart
Why do you play with my mind

Said we’d be forever
Said it’d never die
How could you love me and leave me and never
Say goodbye

When I can’t sleep at night
Without holding you tight
Girl, each time I try I just break down and cry
Pain in my head
Oh, I’d rather be dead
Spinning around and around

(chorus 2x)
Although we’ve come
To the end of the road
Still I can’t let go
It’s unnatural
You belong to me
I belong to you

(chorus)
I wanna take forever tonight
Wanna stay in this moment forever
I’m gonna give you all the love that I’ve got
I wanna take forever tonight
Fill you up, fill you up with love
When we close the door all I need is in your eyes
I wanna take forever tonight

Touch my lips, I’m on fire
You’re the only one I’ll ever desire
Turn the lights down low, make the world go slow
When I’m holding you tonight it’s so easy
Nothing moves me like you do when you tease me
And to rush would be a crime
I just wanna spend some time with you baby

chorus

And when I’m here beside you
I wanna see what drives you out of your mind
I never wanna leave I only wanna be with you
‘Cause I love how you feel your love is so real

I wanna take forever tonight
Wanna stay in this moment forever
I’m gonna give you all the love that I’ve got

I wanna take forever tonight
Wanna stay in this moment forever
I’m gonna give you all the love that I’ve got
‘Cause I can’t live without you

How to solve this?

First you must know exactly which file(s) is / are corrupted. When WinRar gives back the error it says which file(s) is / are corrupted. But to be sure, open each file at a time. When opening each file, if the file is corrupt winrar will give an error immediately.

Now you know which file(s) is / are corrupted

There are 2 Methods to solve this:

Method 1:

Open the corrupted part, and press “ALT + R”

When all went well, the file will be ok.

Alternative Method 1:

Step 1: Open Winrar and navigate to the folder containing the *.rar files. If you open the first file you can navigate to the folder using the up button.

Step 2: Highlight / select all of the files associated with the archive and click the repair button. This will take some time.

Step 3: Use the repaired files to extract the previously corrupted content. The files will have the prefix “rebuilt.” added to them.

Note: Most of the time there are only 1 or 2 corrupted files and there is no need to repair the ones that are OK. To do this, you must know which files are bad and select those files and repair them. Once repaired, delete the original files and remove the “rebuilt.” prefix from the repaired files. Finaly, extract as usual.

If Method 1 does not work please try Method 2.

Method 2:

Step 1: Download the file or files that are corrupted again.

Step 2: Extract using WINRAR. Problem should be solved.

What if these methods did not work:

If you downloaded the file again and it’s still corrupted, make sure your downloads are 100% downloaded. Sometimes the download ends abruptly near the end. Check file size. Usually only the last file has a different size, all others should have the same size. Compare the file sizes to see if the problem is from the download or if it really is the file that’s corrupted.
