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

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.

Another interesting possibility    generate RSA  or DSA key pair  as it was described  put public key to host  as it was already described  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

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

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   gt  amp 2   I had to install sshpass

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

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

The official solution  and others  were incomplete when I first visited  so I came back  years later  to post this alternate approach in case any others wound up here intending to use a public private key-pair   Execute this from the target backup machine  which pulls from source to target backup  rsync -av --delete -e  ssh -p 59333 -i  home user  ssh id rsa  user 10 9 9 3  home user Server   home keith Server   Execute this from the source machine  which sends from source to target backup  rsync -av --delete -e  ssh -p 59333 -i  home user  ssh id rsa   home user Server  user 10 9 9 3  home user Server   And  if you are not using an alternate port for ssh  then consider the more elegant examples below   Execute this from the target backup machine  which pulls from source to target backup   sudo rsync -avi --delete  user 10 9 9 3  var www   media sdb1 backups www   Execute this from the source machine  which sends from source to target backup   sudo rsync -avi --delete  media sdb1 backups www  user 10 9 9 3  var www   If you are still getting prompted for a password  then you need to check your ssh configuration in  etc ssh sshd config and verify that the users in source and target each have the others  respective public ssh key by sending each over with ssh-copy-id user 10 9 9 3    Again  this is for using ssh key-pairs without a password  as an alternate approach  and not for passing the password over via a file

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
