how to pass password for rsync ssh command

问题:

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

回答1:

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.

Instructions for setting up passwordless ssh access

回答2:

Use "sshpass" non-interactive ssh password provider utility

On Ubuntu

 sudo apt-get install sshpass

Command to rsync

 /usr/bin/rsync -ratlz --rsh="/usr/bin/sshpass -p password ssh -o StrictHostKeyChecking=no -l username" src_path  dest_path

回答3:

You can avoid the password prompt on rsync command by setting the environment variable RSYNC_PASSWORD to the password you want to use or using the --password-file option.

回答4:

If you can't use a public/private keys, you can use expect:

#!/usr/bin/expect
spawn rsync SRC DEST
expect "password:"
send "PASS\n"
expect eof
if [catch wait] {
    puts "rsync failed"
    exit 1
}
exit 0

You will need to replace SRC and DEST with your normal rsync source and destination parameters, and replace PASS with your password. Just make sure this file is stored securely!

use a ssh key :

look at ssh-keygen and ssh-copy-id.

After that you can use an rsync this way :

rsync -a --stats --progress --delete /home/path server:path

回答6:

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)

回答7:

Though you've already implemented it by now,

you can also use any expect implementation (you'll find alternatives in Perl, Python: pexpect, paramiko, etc..)

回答8:

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

回答9:

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}"

回答10:

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

回答11:

I work out so

sshpass -p "password" rsync -ae "ssh -p remote_port_ssh" /local_dir remote_user@remote_host:/remote_dir

回答12:

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

echo "SuperHardToGuessPass:P" | sshfs -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no [e-mail]:/mypath/ /mnt/source-tmp/ -o workaround=rename -o password_stdin
rsync -a /mnt/source-tmp/ /media/destination/
umount /mnt/source-tmp
