I need to ssh into a machine and execute a bunch of commands under sudo bash. Here is what I've tried:
sshpass -p "vagrant" ssh vagrant#33.33.33.100 "sudo bash -i -c <<EOF
echo
ls
echo
EOF"
But it throws me 'bash: -c: option requires an argument\n'. How can I fix this?
You need to remove -c from your command line to make it accept heredoc:
sshpass -p "vagrant" ssh vagrant#33.33.33.100 "sudo bash <<EOF
echo
ls
echo
EOF"
Also you may remove -i (interactive) option too.
bash -c expects you to provide all commands on command line so this may work too:
sshpass -p "vagrant" ssh vagrant#33.33.33.100 "sudo bash -c 'echo; ls; echo'"

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"
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 getting incredibly frustrated here. I simply want to run a sudo command on a remote SSH connection and perform operations on the results I get locally in my script. I've looked around for close to an hour now and not seen anything related to that issue.
When I do:
#!/usr/bin/env bash
OUT=$(ssh username#host "command" 2>&1 )
echo $OUT
Then, I get the expected output in OUT.
Now, when I try to do a sudo command:
#!/usr/bin/env bash
OUT=$(ssh username#host "sudo command" 2>&1 )
echo $OUT
I get "sudo: no tty present and no askpass program specified". Fair enough, I'll use ssh -t.
#!/usr/bin/env bash
OUT=$(ssh -t username#host "sudo command" 2>&1 )
echo $OUT
Then, nothing happens. It hangs, never asking for the sudo password in my terminal. Note that this happens whether I send a sudo command or not, the ssh -t hangs, period.
Alright, let's forget the variable for now and just issue the ssh -t command.
#!/usr/bin/env bash
ssh -t username#host "sudo command" 2>&1
Then, well, it works no problem.
So the issue is that ssh -t inside a variable just doesn't do anything, but I can't figure out why or how to make it work for the life of me. Anyone with a suggestion?
If your script is rather concise, you could consider this:
#!/usr/bin/env bash
ssh -t username#host "sudo command" 2>&1 \
| ( \
read output
# do something with $output, e.g.
echo "$output"
)

I would like to know how can I run shell commands in a remote machine.
I tried this:
ssh prdcrm1#${server} "grep -l 'Sometthing' *"
It is working, but I want to run more commands.
Do someone has an Idea?
You can run multiple commands on remote machine like,
Run date and hostname commands:
$ ssh user#host "date && hostname"
Run a script called /scripts/backup.sh
ssh user#host '/scripts/backup.sh'
Run sudo or su command using the following syntax
ssh user#host su --session-command="/sbin/service httpd restart"
ssh -t user#host 'sudo command1 arg1 arg2' ## su syntax ##
Multi-line command with variables expansion
VAR1="Variable 1"
ssh $HOST bash -c "'
ls
pwd
if true; then
echo $VAR1
else
echo "False"
fi
'"
Hope these helps you.
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
