I try to run a local script using ssh
ssh remotehost 'bash -s' < test.sh
test.sh is
#!/bin/bash
echo "Start Script"
sudo echo "test"
echo "End Script"
Also, in remote host, sudo logging is enabled in /etc/sudoers
Defaults logfile="/var/log/sudo.log"
Defaults log_input,log_output
After this, the output of ssh remotehost 'bash -s' < test.sh is
Start Script
test
Script got terminated after executing the first sudo command. But I need to get
Start Script
test
End Script
I also tried ssh -T remotehost 'bash -s' < test.sh, unfortunately it's not working.
What's the prope way to do this? Thanks

I've installed some software on a server that my gitlab runner SSH's to, and one of the commands needs to be run after doing sudo su. If I run it as a regular user, but with sudo in front of it - it doesn't work. I have to first completely switch to the sudo user first.
This works fine when I SSH into the server and do the commands manually. But when I try it from the pipeline (rough code below):
my_script:
stage: stage
script:
- ssh -o -i id_rsa -tt user#1.1.1.1 << EOF
- sudo su
- run_special_command <blah blah>
- exit
# above exits from the SSH. below should stop the pipeline
- exit 0
- EOF
I get very weird output like the below:
$ sudo su
[user#1.1.1.1 user]$ sudo su
echo $'\x1b[32;1m$ run_special_command <blah blah>\x1b[0;m'
run_special_command <blah blah>
echo $'\x1b[32;1m$ exit\x1b[0;m'
exit
echo $'\x1b[32;1m$ exit 0\x1b[0;m'
exit 0
echo $'\x1b[32;1m$ EOF\x1b[0;m'
And what I'm seeing is that it doesn't even run the command at all - and I can't figure out why.
In this case, you need to put your script as a multi-line string in your YAML. Alternatively, commit a shell script to repo and execute that.
and one of the commands needs to be run after doing sudo su. If I run it as a regular user, but with sudo in front of it - it doesn't work.
As a side note, you can probably use sudo -E instead of sudo su before the command. But what you have should also work with the multi-line script.
MyJob:
script: |
ssh -o -i id_rsa -tt user#host << EOF
sudo -E my_command
EOF
exit 0
Alternatively, write your script into a shell script committed to the repository (with executable permissions set) and run it from your job:
MyJob:
script: “my_script.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 am trying to write a deployment script which after copying the new release to the server should perform a few sudo commands on the remote machine.
#!/bin/bash
app=$1
echo "Deploying application $app"
echo "Copy file to server"
scp -pr $app-0.1-SNAPSHOT-jar-with-dependencies.jar nuc:/tmp/
echo "Execute deployment script"
ssh -tt stefan#nuc ARG1=$app 'bash -s' <<'ENDSSH'
# commands to run on remote host
echo Hello world
echo $ARG1
sudo ifconfig
exit
ENDSSH
The file gets copied correctly and the passed argument printed as well. But the prompt for the password shows for two seconds then it says "Sorry, try again" and the second prompt shows the text I enter in plain text (meaning not masked) but also does not work if I enter the password correctly.
stefan#X220:~$ ./deploy.sh photos
Deploying application photos
Copy file to server
photos-0.1-SNAPSHOT-jar-with-dependencies.jar 100% 14MB 75.0MB/s 00:00
Execute deployment script
# commands to run on remote host
echo Hello world
echo $ARG1
sudo ifconfig
exit
stefan#nuc:~$ # commands to run on remote host
stefan#nuc:~$ echo Hello world
Hello world
stefan#nuc:~$ echo $ARG1
photos
stefan#nuc:~$ sudo ifconfig
[sudo] password for stefan:
Sorry, try again.
[sudo] password for stefan: ksdlgfdkgdfg
I tried leaving out the -t flags for ssh as well as using -S for sudo which did not help. Any help is highly appreciated.
What I would do :
ssh stefan#nuc bash -s foobar <<'EOF'
echo "arg1 is $1"
echo "$HOSTNAME"
ifconfig
exit
EOF
Tested, work well.
Notes :
for the trick to work, use ssh key pair instead of using a password, it's even more secure
take care of the place of your bash -s argument. Check how I pass it
no need -tt at all
no need sudo to execute ifconfig and better use ip a
I came up with another solution: Create another file with the script to execute on the remote server. Then copy it using scp and in the calling script do a
ssh -t remoteserver sudo /tmp/deploy_remote.sh parameter1
This works as expected. Of course the separate file is not the most elegant solution, but -t and -tt did not work when inlining the script to execute on the remote machine.
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 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'
