i need execute remotly an asterisk command via SSH and get the output.
The command to execute is this:
asterisk -rx "core show channels"
and i run remotely this:
sshpass -p PASSWORD ssh HOST asterisk -rx 'core show channels'
but i get
No such command 'core' (type 'core show help core' for other possible commands)
PD: When i run the first command locally I dont get the same, it's runs correctly.
This problem does not happen if i exect a no asterisk command. Example "ls -l"
Any help ?
Try
sshpass -p PASSWORD ssh HOST "/usr/sbin/asterisk -rx 'core show channels'"

I'm using localhost.run to open tunnels, so I want to launch
ssh -R 80:localhost:8080 ssh.localhost.run
The only problem is that I launch it via LSF as part of a bash script.
I get the error
Pseudo-terminal will not be allocated because stdin is not a terminal.
that I solve by using the option
-T Disable pseudo-tty allocation.
My current command is
ssh -T -R 80:localhost:8080 ssh.localhost.run
and it is the last command of my bash script.
I have also tried using -tt with the same result (https://stackoverflow.com/a/7122115/5133167)
When I launch my script from my tty, I get the expected output (a message like Connect to http://user.localhost.run or https://user.localhost.run)
When I launch it through LSF (using bsub), I don't get any output from SSH (but get the output from the other commands).
I have also tried redirecting the output of ssh to a file: it works fine when launched from the command line but not when launched from LSF.
Using the GUI putty.exe, I can connect to my windows server and once it is connected, i can type any command like rename file or mkdir folder and they all work
However, using command line such as
putty -load test -m C:\users\test.txt
or using the GUI putty, but add 1 command to remote command in SSH under Connection, then the command doesn't get executed.
Can anyone explain to me why this is happening or how can i fix this? I am using FreeSSHd on windows 2008 server.
Not sure if this helps, but try adding the /bin/bash directly after your command in the text file. It will keep the window open and you can see what the output of the shell would be if you ran it from the gui.
; /bin/bash
For example if test.txt is running a script
bash myscript.sh
bash myscript.sh; /bin/bash
This is assuming bash.
I'm trying to login to a ssh server and to execute something like:
ssh user#domain.com 'sudo echo "foobar"'
Unfortunately I'm getting an error:
sudo: no tty present and no askpass program specified
Google told me to either set the environment variable SSH_ASKPASS or to set askpass in the sudoers file. My remote machine is running on Debian 6 and I've installed the packages ssh-askpass and ssh-askpass-gnome and my sudoers file looks like this:
Defaults env_reset
Defaults askpass=/usr/bin/ssh-askpass
# User privilege specification
root ALL=(ALL) ALL
user ALL=(ALL) ALL
Can someone tell what I'm doing wrong and how to do it better.
There are two ways to get rid of this error message. The easy way is to provide a pseudo terminal for the remote sudo process. You can do this with the option -t:
ssh -t user#domain.com 'sudo echo "foobar"'
Rather than allocating a TTY, or setting a password that can be seen in the command line, do something like this.
Create a shell file that echo's out your password like:
#!/bin/bash
echo "mypassword"
then copy that to the node you want using scp like this:
scp SudoPass.sh somesystem:~/bin
Then when you ssh do the following:
ssh somesystem "export SUDO_ASKPASS=~/bin/SudoPass.sh;sudo -A command -parameter"
Another way is to run sudo -S in order to "Write the prompt to the standard error and read the password from the standard input instead of using the terminal device" (according to man) together with cat:
cat | ssh user#domain.com 'sudo -S echo "foobar"'
Just input the password when being prompted to.
One advantage is that you can redirect the output of the remote command to a file without "[sudo] password for …" in it:
cat | ssh user#domain.com 'sudo -S tar c --one-file-system /' > backup.tar
Defaults askpass=/usr/bin/ssh-askpass
ssh-askpass requires X server, so instead of providing a terminal (via -t, as suggested by nosid), you may forward X connection via -X:
ssh -X user#domain.com 'sudo echo "foobar"'
However, according to current documentation, askpass is set in sudo.conf as Path, not in sudoers.
How about adding this in the sudoers file:
user ALL=(ALL) NOPASSWD: ALL
I want to run a script remotely. But the system doesn't recognize the path. It complains that "no such file or directory". Am I using it right?
ssh kev#server1 `./test/foo.sh`
You can do:
ssh user#host 'bash -s' < /path/script.sh
Backticks will run the command on the local shell and put the results on the command line. What you're saying is 'execute ./test/foo.sh and then pass the output as if I'd typed it on the commandline here'.
Try the following command, and make sure that thats the path from your home directory on the remote computer to your script.
ssh kev#server1 './test/foo.sh'
Also, the script has to be on the remote computer. What this does is essentially log you into the remote computer with the listed command as your shell. You can't run a local script on a remote computer like this (unless theres some fun trick I don't know).
If you want to execute a local script remotely without saving that script remotely you can do it like this:
cat local_script.sh | ssh user#remotehost 'bash -'
It works like a charm for me.
I do that even from Windows to Linux given that you have MSYS installed on your Windows computer.
I don't know if it's possible to run it just like that.
I usually first copy it with scp and then log in to run it.
scp foo.sh user#host:~
ssh user#host
./foo.sh
I was able to invoke a shell script using this command:
ssh ${serverhost} "./sh/checkScript.ksh"
Of course, checkScript.ksh must exist in the $HOME/sh directory.
Make the script executable by the user "Kev" and then remove the try it running through the command
sh kev#server1 /test/foo.sh
i want to run some command on several machine using ssh. I know it can be done by just using the command "ssh user#hostname command". However, the command i want to run print some string on the console. Is there any way that send all the strings back to the console that i'm on?
You could run the commands in a screen:
screen -S test
ssh user#hostname command1
ssh user#hostname2 command2
You can then detach (Ctrl-D) from the screen, let it run for however long it will run, then re-attach (screen -r test) to the screen and see all of the output. This assumes that you won't have a ton of output from the commands, however. Here's a link to a tutorial on screen.
ssh user#hostname command
Does just that. if 'command' outputs something, it'll show on the terminal you ran ssh from.
Try e.g. ssh user#hostname ls -l
But as others have said, GNU screen is invaluable for this type of work.
You probably want to use Gnu Screen for this. You can start a process in a "virtual" terminal, "detach" the terminal and log out for however long you want... Then you can ssh back in and re-attach the terminal to see the console output.
Also have a look at nohup, for example:
ssh user#domain.com nohup script_that_outputs_strings.py > the_strings.txt
Then if you want to go back and monitor the progress, you could check back and tail the file or scp the output back to your local machine.
Why don't you send you an email back?
Or use a log file, and scp it to your current computer?
otherwise, I don't know!
