Command Line SFTP with SCP

FettesPS — Wed, 09 Feb 2011 12:00:34 +0000

If you’re making a batch file that requires you to upload some files over SFTP/SCP then you’ll need to use an external program such as WinSCP that has command line access to upload the files. Unfortunately you cannot use the native FTP client in Windows. First create a config file with your server settings and save it in the same directory as your batch file. I also make use of an RSA key pair for added security, in this example that public key will be saved as key.ppk using PuTTY’s key format.

# Automatically answer all prompts negatively not to stall
# the script on errors
option batch on

# Disable overwrite confirmations that conflict with the previous
option confirm off

# Connect using a password
# open user:password@example.com
# Connect
open sftp://user:pass@ip:22 -hostkey="ssh-rsa 2048 ba:52:06:a7:7a:4a:17:1e:49:a9:ef:ae:08:5b:90:54" -privatekey="key.ppk"

# Change remote directory
cd /home/user/files

# Force binary mode transfer
option transfer binary

# Upload file to the server
put file2upload.jar

# Disconnect
close

# Exit WinSCP
exit

Now in your batch file, after you’re done compiling or what ever it is you need to do first, add this line (making sure to replace the path for WinSCP with the one you’ve used on your system):

"C:\Program Files (x86)\WinSCP\WinSCP.exe" /console /script=sftp.scp

Installing Pure-FTPd on Ubuntu 9.04 Server

Although I no longer install FTP servers on any of my Linux servers, as I favour the user of SFTP, I wanted to update my instructions for the newest version of Ubuntu Server. I’m sure these instructions are very similar for most distributions, but I thought I’d specifically target Ubuntu 9.04 Server since that is what I am most familiar with.
sudo apt-get install pure-ftpd

When prompted, enter Y and hit enter.

Now, set up a new account using the ‘useradd’ command. You’ll also need to specify the home directory for the user by adding ‘-d /home/directoryname -m’ so when the user logs in they have a folder to upload/download files from. You don’t have to use the /home dirctory for this but I always do to make things simple. Here is the command I used.

sudo useradd -d /home/username -m username sudo passwd username

Since I don’t want this user being able to cruise through the file system and see everything I’m going to lock the user to the home directory we just made. Open up /etc/passwd for editing. I use pico for this, you can use whatever program you like. Search for the user you just made (ctrl+w in pico) and add /./ to their home directory like this:

sudo pico /etc/passwd /home/username/./

Note that the line will be a lot messier than that, so just squeeze it in where appropriate. Also, make sure to put in a shell at the end of that line… /bin/bash works fine. After all of that, add their username to /etc/ftpallow if you want to manually allow access to certain accounts.

Now just type pure-ftpd-control restart on the command line and you’re ready to test out your account! Hop on another computer, or just SSH into another one and try from there. If it doesn’t work its possible your install didn’t set up some of the proper configuration. This happens automatically on Ubuntu 9.04 Server but on other distrobutions you may need to perform this next step.

Edit /etc/pam.d/pure-ftpd using your favourite editor to look like this:

auth sufficient pam_ftp.soauth required pam_unix_auth.so shadow use_first_pass
auth required pam_listfile.so item=user sense=deny file=/etc/ftpusers onerr=succeed
auth required pam_listfile.so item=user sense=allow file=/etc/ftpallow onerr=fail
auth required pam_shells.so

Save the file, restart the server again and try it out again. If you’re having troubles still I suggest seeking help from the Documentation.

Installing Pure-FTPd on Ubuntu 8.04 Server

Until recently my choice for an FTP server had always been ProFTPd, however I found its difficulty to install made it a constant chore every time I had to set up a server. So I sought out an alternative that was quick and easy to install yet did not sacrifice functionality or security. The answer was Pure-FTPd.

I’m sure these instructions are very similar for most distributions, but I thought I’d specifically target Ubuntu 8.04 Server since that is what I am installing it on today. If you are using the desktop edition of Ubuntu or another distrobution that has a GUI you can most likely use that alternative. Instead of apt-get commands you would simply fire up the Synaptic Package Manager and search for the install package.

I tend to jump right to the super user when I log in (bad habit, I know). So if you’re not doing that you will have to prefix all commands with ‘sudo’ or they might not work. Start off by installing the program and all of its required packages.

apt-get install pure-ftpd

When prompted, enter Y and hit enter.

useradd -d /home/username -m username
passwd username

/home/username/./

Note that the line will be a lot messier than that, so just squeeze it in where appropriate.

Also, make sure to put in a shell at the end of that line… /bin/bash works fine. After all of that, add their username to /etc/ftpallow if you want to manually allow access to certain accounts.

Now just type pure-ftpd-control restart on the command line and you’re ready to test out your account! Hop on another computer, or just SSH into another one and try from there. If it doesn’t work its possible your install didn’t set up some of the proper configuration. This happens automatically on Ubuntu 8.04 Server but on other distrobutions you may need to perform this next step.

Edit /etc/pam.d/pure-ftpd using your favourite editor to look like this:

auth sufficient pam_ftp.so
auth required pam_unix_auth.so shadow use_first_pass
auth required pam_listfile.so item=user sense=deny file=/etc/ftpusers onerr=succeed
auth required pam_listfile.so item=user sense=allow file=/etc/ftpallow onerr=fail
auth required pam_shells.so

Save the file, restart the server again and try it out again. If you’re having troubles still I suggest seeking help from the Documentation.
