Previously I downloaded a CSV file from an SFTP server using SSHPASS where the authentication method was through username/password and not public key:
sshpass -p [SFTP_SERVER_PASSWORD] sftp -o StrictHostKeyChecking=no -o HostKeyAlgorithms=+ssh-dss [USERNAME]#ftp1.exacttarget.com <<EOF
get -r /Export/MyFile.csv
EOF
The SFTP server has now added the public key (created on my Ubuntu server) and so I would like to change the command above to communicate without a password. What options should I add/remove?
As you don't need sshpass any longer, change your call to
sftp -o StrictHostKeyChecking=no -o HostKeyAlgorithms=+ssh-dss [USERNAME]#ftp1.exacttarget.com <<EOF
get -r /Export/MyFile.csv
EOF

Hi i created following script to initialize my storage box to use rsync without password later. Last year it works if i remember correct...
cat .ssh/id_rsa.pub >> .ssh/storagebox_authorized_keys
echo -e "mkdir .ssh \n chmod 700 .ssh \n put $.ssh/storagebox_authorized_keys" \
".ssh/authorized_keys \n chmod 600 .ssh/authorized_keys" | sshpass -p ${storage_password} \
sftp -P ${storage_port} -i .ssh/id_rsa ${storage_user}#${storage_address}
today I get following error:
sshpass: invalid option -- 'i'
but the parameter -i belongs to sftp and not sshpass - is there an possibility to parse the parameters in the correct way?
edit: i switched the position of
-i .ssh/id_rsa ${storage_user}#${storage_address}
and get this error
sshpass: Failed to run command: No such file or directory
edit: it seems like an sftp problem...
after discussion, updating answer to properly support automation
step 1:
create an sftp "batch file" e.g: ~/.ssh/storage-box_setup.sftp
mkdir .ssh
chmod 700 .ssh
put /path/to/authorized_keys_file ".ssh/authorized_keys
chmod 600 .ssh/authorized_keys
/path/to/authorized_keys_file is a file containing public keys of ONLY the keys that should have access to your storage box (.ssh/storagebox_authorized_keys)
step 2:
update automation script command to
sshpass -p <password> -- sftp -P <port> -b ~/.ssh/storage-box_setup.sftp user#host
the -b flag was the answer you needed.
refer: man sftp
-b batchfile
Batch mode reads a series of commands from an input batchfile instead of stdin. Since it lacks user interaction it should be used in conjunction with non-interactive authentication.
--
sshpass -p ${storage_password} -- \
sftp -P ${storage_port} -i .ssh/id_rsa \
${storage_user}#${storage_address}
the -- before sftp is a way to tell sshpass (and most other programs) to stop parsing arguments.
everything after -- is assumed as the last argument, which in the case of sshpass is the command to be executed ssh -i ~/.id_rsa ...
in case you're wondering switching the position of -i tells sshpass to execute -i as a program and hence fails with command not found
I'm trying to run a bash script on the remote server that is already on the remote server. I'm using ssh pass to do it but I'm seeing errors
test.sh (resides on the remote server)
#!/usr/bin/env bash
echo "This is test"
adb start-server
sshpass command (I'm running this sshpass command from docker ubuntu image
sshpass -p password ssh -oStrictHostKeyChecking=no -oCheckHostIP=no user#host "bash -s" < /Users/user/Documents/workspace/test.sh
I also tried
sshpass -p password ssh -oStrictHostKeyChecking=no -oCheckHostIP=no user#host 'cd /Users/user/Documents/workspace/; sh test.sh'
I get this error message
bash: /Users/user/Documents/workspace/test.sh: No such file or directory
The examples you're showing are for a local script, and you said it's a remote script.
sshpass -p password ssh -oStrictHostKeyChecking=no -oCheckHostIP=no user#host "bash /path/to/test.sh"
that ought to do it.
you can try to find your test.sh on the remote computer:
sshpass -p password ssh -oStrictHostKeyChecking=no -oCheckHostIP=no user#host "find ~/ -name \"test.sh\""
Try with here-document:
sshpass -p password ssh -oStrictHostKeyChecking=no -oCheckHostIP=no -T user#host <<EOF
bash /Users/user/Documents/workspace/test.sh
EOF
Include -T option for ssh command, as mentioned above, to disable pseudo-tty.
[AT REMOTE MATCHINE] Ensure that path of adb executable is included in PATH environment variable. Else, specify it with absolute path in the Shell script.
I'm an Ubuntu bash newbie. I successfully login to an sFTP server using sshpass. But once the connection is established I also need to download a directory from the server. My script cannot seem to pass the connection line though. This is what I have in my script (.sh) file:
#!/bin/bash
sshpass -p 'MY_PASSWORD' sftp -o StrictHostKeyChecking=no -o HostKeyAlgorithms=+ssh-dss MYUSER#MYSFTPSERVERADDRESS
echo "hello"
get -r Export
In the snipped above, my echo and my get are not executed. The terminal is waiting for my input with a sftp> prompt.
You would be better served using scp instead of sftp and sharing keys instead of putting the password in a script if you're able, but if you must use sftp for some reason, it can take its commands from a heredoc like:
sshpass -p 'MY_PASS' sftp -o StrictHostKeyChecking=no -o HostKeyAlgorithms=+ssh-dss MYUSER#MYSFTPSERVERADDRESS <<EOF
get -r Export
EOF
note that echo isn't a valid sftp command.
You can put whatever commands you want sftp to execute before the EOF and it will do them each in turn.
If all you want is to get that directory it's probably still simpler to use scp if you can:
sshpass -p 'MY_PASSWORD' scp -o StrictHostKeyChecking=no -o HostKeyAlgorithms=+ssh-dss -r MYUSER#MYSFTPSERVERADDRESS:Export .
I (very) recently posted this question in regards to tar over ssh.
The question now has an answer, and I am now asking a different question.
I run the following command to push code from my local machine to my server where it will run.
tar -cJf - ./my_folder | ssh user#example 'tar -xJf - -C ./path-to-my_folder/'
I know that with ssh/scp I can use sshpass -p password to stop the command asking for my password each time. Note that I cannot use alternative methods of authentication.
Is it possible to combine sshpass with my above command so that I do not have to enter my password continually?
In other words how should I edit the above command to include sshpass so that I do not have to type in my password each time the above command runs?
Edit: Note the following does work
For example
sshpass -p <password> ssh ... blaa blaa
sshpass -p <password> scp ... blaa blaa
I think you can use something like this:
tar -cJf - ./my_folder | sshpass -p $remote_ssh_password ssh -o StrictHostKeyChecking=no $remote_ssh_username#$remote_web_address "tar -xJf - -C ./path-to-my_folder/"
Note: StrictHostKeyChecking=no for avoiding prompt for server's fingerprint confirmation. It could create a security issue:
"Therefore, if you want to know whether you are talking to the right server (and not some impersonator), then you "just" need to compute the server's key fingerprint (from the public key that the server just sent to you) and compare it with a "reference fingerprint"."

I work with a couple of arduino yuns and want to write a script to upload sketches on multiple of them. Let's assume I have a compiled arduino program:sketch.hex.
Now I'd like to upload this file via LAN. For a single device it works like this.
Copying the sketch onto the device. (password required)
scp sketch.hex root#yun1.local:/tmp/sketch.hex
Opening an ssh session with the device. (password required)
ssh root#yun1.local
And then load the program onto the Atmega with the following 2 commands.
merge-sketch-with-bootloader.lua /tmp/sketch.hex
run-avrdude /tmp/sketch.hex
Now my question would be, how to do this for multiple arduinos (yun1,yun2,...,yunN) without entering actually ssh-ing into each single device in order to run the bottom 2 commands.
Hope the question is not too confusing and thanks a lot in advance.
Update: could figure it out myself. Here is the code in case someone needs it.
