How to pass password automatically for rsync SSH command?

Question

I need to do rsync by ssh and want to do it automatically without the need of passing password for ssh manually.

Answer 1

The following works for me:

SSHPASS='myPassword'
/usr/bin/rsync -a -r -p -o -g --progress --modify-window=1 --exclude /folderOne -s -u --rsh="/usr/bin/sshpass -p $SSHPASS ssh -o StrictHostKeyChecking=no -l root"  source-path  myDomain:dest-path  >&2

I had to install sshpass

Answer 2

You should use a keyfile without passphrase for scripted ssh logins. This is obviously a security risk, take care that the keyfile itself is adequately secured.

Answer 3

Automatically entering the password for the rsync command is difficult. My simple solution to avoid the problem is to mount the folder to be backed up. Then use a local rsync command to backup the mounted folder.

mount -t cifs //server/source/ /mnt/source-tmp -o username=Username,password=password
rsync -a /mnt/source-tmp /media/destination/
umount /mnt/source-tmp

Answer 4

Another interesting possibility:

1. generate RSA, or DSA key pair (as it was described)
2. put public key to host (as it was already described)
3. run:

rsync --partial --progress --rsh="ssh -i dsa_private_file" host_name@host:/home/me/d .

Note: -i dsa_private_file which is your RSA/DSA private key

Basically, this approach is very similar to the one described by @Mad Scientist, however you do not have to copy your private key to ~/.ssh. In other words, it is useful for ad-hoc tasks (one time passwordless access)

Answer 5

Following the idea posted by Andrew Seaford, this is done using sshfs:

echo "SuperHardToGuessPass:P" | sshfs -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no user@example.com:/mypath/ /mnt/source-tmp/ -o workaround=rename -o password_stdin
rsync -a /mnt/source-tmp/ /media/destination/
umount /mnt/source-tmp

Answer 6

I use a VBScript file for doing this on Windows platform, it servers me very well.

set shell = CreateObject("WScript.Shell")
shell.run"rsync -a Name@192.168.1.100:/Users/Name/Projects/test ."
WScript.Sleep 100
shell.SendKeys"Your_Password"
shell.SendKeys "{ENTER}"
