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 trying to run a script on a remote server with either password credentials or .pem key access and I'm getting errors no matter which solution I've found etc.
bash script content:
#!/bin/bash
sudo fdisk -l
ssh -T -i "~/.ssh/keys/key.pem" ubuntu#host "sudo bash <(wget -qO- http://host.com/do.sh)"
Error: bash: /dev/fd/63: No such file or director
ssh user#host.com 'echo "password" | sudo bash <(wget -qO- http://www.host.io/do.sh)'
Error: sudo: a password is required
ssh -t user#host.com "echo password | sudo fdisk -l"
Works but still gives me the password propmt
echo -t pass | ssh user#host "sudo bash <(wget -qO- http://host.com/do.sh)"
echo -tt pass | ssh user#host "sudo bash <(wget -qO- http://host.com/do.sh)"
Error: bash: /dev/fd/63: No such file or directory
// And I also get the password prompt
echo -tT pass | ssh user#host "sudo bash <(wget -qO- http://host.com/do.sh)"
Error: sudo: a terminal is required to read the password; either use the -S option to read from standard input or configure an askpass helper
sudo: a password is required
// And I also get the password prompt
// This works but I still get the password propmt
ssh user#host 'echo "password" | sudo -S sudo fdisk -l'
These are different variations of the supposed solutions from other places.
What I'm trying to do:
Is to run a script from a URL on the remote server while echoing the password to the cmd so I don't get propmt to input the password manually.
To be able to do the same thing above with using the .pem key variant also
For an explanation for commands except the first one, You can't do stdin-redirect a password to ssh if ssh requires interactively. ssh only allows manual typing if you use a password.
Your first error said that bash can't read a file descriptor. So ssh via ~/.ssh/keys/key.pem works. To run the shell command on the fly,
ssh -T -i "~/.ssh/keys/key.pem" ubuntu#host "curl -fsSL http://host.com/do.sh | sudo bash"
Does your script really need to run with sudo??
If not, then try this:
ssh user#host "curl -s -o do.sh 'http://host.com/do.sh'; source do.sh"
Client OS: MacOS 12.1, Server OS: Linux Debian 9 (any server)
case 1:
#!/bin/bash
sshpass -p mypass ssh user#host.ru -o StrictHostKeyChecking=no
works fine:
case 2:
#!/bin/bash
sshpass -p mypass ssh user#host.ru -o StrictHostKeyChecking=no "cd /var/www ; git status ; /bin/bash"
Output of "git status" works fine, but
no "user#host:~$" message in output (input is active).
I tried:
/bin/bash
bash -l
(in server "echo $SHELL" shows /bin/bash)
How to fix it?
Use ssh -t and && inside commands list
#!/bin/bash
sshpass -p mypass ssh -t user#host.ru -o StrictHostKeyChecking=no "cd /var/www && git status && /bin/bash"
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 have a script which starts an ssh-connection.
so the variable $ssh start the ssh connection.
so $SSH hostname gives the hostname of the host where I ssh to.
Now I try to echo something and copy the output of the echo to a file.
SSH="ssh -tt -i key.pem user#ec2-instance"
When I perform a manual ssh to the host and perform:
sudo sh -c "echo 'DEVS=/dev/xvdbb' >> /etc/sysconfig/docker-storage-setup"
it works.
But when I perform
${SSH} sudo sh -c "echo 'DEVS=/dev/xvdb' > /etc/sysconfig/docker-storage-setup"
it does not seem to work.
EDIT:
Also using tee is working fine after performing an ssh manually but does not seem to work after the ssh in the script.sh
The echo command after an ssh of the script is happening on my real host (from where I'm running the script, not the host where I'm performing an ssh to). So the file on my real host is being changed and not the file on my host where I've performed an ssh to.
The command passed to ssh will be executed by the remote shell, so you need to add one level of quoting:
${SSH} "sudo sh -c \"echo 'DEVS=/dev/xvdb' > /etc/sysconfig/docker-storage-setup\""
The only thing you really need on the server is the writing though, so if you don't have password prompts and such you can get rid of some of this nesting:
echo 'DEVS=/dev/xvdb' | $SSH 'sudo tee /etc/sysconfig/docker-storage-setup'
I am trying to run a sshpass command inside a bash script but it isn't working.
If I run the same command from the terminal it works fine but running it in a bash script it doesn't.
#! /bin/bash
sshpass -p 'password' ssh user#host command
I am aware of the security issues but its not important now.
Can someone help? Am I missing something.
Thanks
Try the "-o StrictHostKeyChecking=no" option to ssh("-o" being the flag that tells ssh that your are going to use an option). This accepts any incoming RSA key from your ssh connection, even if the key is not in the "known host" list.
sshpass -p 'password' ssh -o StrictHostKeyChecking=no user#host 'command'
Do which sshpass in your command line to get the absolute path to sshpass and replace it in the bash script.
You should also probably do the same with the command you are trying to run.
The problem might be that it is not finding it.
1 - You can script sshpass's ssh command like this:
#!/bin/bash
export SSHPASS=password
sshpass -e ssh -oBatchMode=no user#host
2 - You can script sshpass's sftp commandlike this:
#!/bin/bash
export SSHPASS=password
sshpass -e sftp -oBatchMode=no -b - user#host << !
put someFile
get anotherFile
bye

I didn't understand how the accepted answer answers the actual question of how to run any commands on the server after sshpass is given from within the bash script file. For that reason, I'm providing an answer.
After your provided script commands, execute additional commands like below:
sshpass -p 'password' ssh user#host "ls; whois google.com;" #or whichever commands you would like to use, for multiple commands provide a semicolon ; after the command
In your script:
#! /bin/bash
sshpass -p 'password' ssh user#host "ls; whois google.com;"
This worked for me:
#!/bin/bash
#Variables
FILELOCAL=/var/www/folder/$(date +'%Y%m%d_%H-%M-%S').csv
SFTPHOSTNAME="myHost.com"
SFTPUSERNAME="myUser"
SFTPPASSWORD="myPass"
FOLDER="myFolderIfNeeded"
FILEREMOTE="fileNameRemote"
#SFTP CONNECTION
sshpass -p $SFTPPASSWORD sftp $SFTPUSERNAME#$SFTPHOSTNAME << !
cd $FOLDER
get $FILEREMOTE $FILELOCAL
ls
bye
!
Probably you have to install sshpass:
sudo apt-get install sshpass
