i was created a bash script my_vp.sh that use 2 command:
setterm -cursor off
setterm -powersave off
[...]
#execute video commands
[...]
and is in a computerA
but when i execute it by ssh by another computerB_terminal:
ssh pi#192.168.1.1
execute video commands work correctly in the computerA (the same where is the script)
but the command setterm works in the computerB (the terminal where i execute the ssh command).
somebody can help me with solucione it?
thank you very much!
I am not sure I understood the question:
to execute a local script, but on another machine:
scp /path/to/local/script.bash pi#192.168.1.1:/tmp/copy_of_script.bash
and then, if it's copied correctly, execute it:
ssh pi#192.168.1.1 "chmod +x /tmp/copy_of_script.bash"
ssh pi#192.168.1.1 "bash /tmp/copy_of_script.bash"
to have the remote video (Xwindows, etc) commands appear on the originating machine:
replace : ssh with : ssh -x (to allow X-Forwarding, which will allocate a DISPLAY automatically on the remote machine that will be tunneled back to the originating machine)
for the X-forwarding to work, there are some requirements (usually ok by default, but ymmv) : read more about those requirements in this Unix.se answer

I'm wondering what the -T option in the following command does, cannot see this option in the manual somehow:
$ ssh -T git#gitlab.com
Welcome to GitLab, Simeon !
Could somebody explain?
I explained before what TTY was: a text terminal is needed when you open an interactive session to a remote server.
But: in the context of a remote Git repository hosting server (GitHub, Gitlab, BitBucket, ...), no remote server will ever allow you to open an interactive session (for security reason)
Then only reason why you would still do an ssh -T git#github.com would be to test if you are correctly authenticated, and the session would immediately end with:
Hi username! You've successfully authenticated,
but GitHub does not provide shell access.
Since no tty is needed for that test, you should use the -T option when making this test.
I am trying to run rsync as follows and running into error sshpass: Failed to run command: No such file or directory .I verified the source /local/mnt/workspace/common/sectool and destination directories/prj/qct/wlan_rome_su_builds are available and accessible?what am I missing?how to fix this?
username#xxx-machine-02:~$ sshpass –p 'password' rsync –progress –avz –e ssh /local/mnt/workspace/common/sectool cnssbldsw#hydwclnxbld4:/prj/qct/wlan_rome_su_builds
sshpass: Failed to run command: No such file or directory
Would that be possible for you to check whether 'rsync' works without 'sshpass'?
Also, check whether the ports used by rsync is enabled. You can find the port info via cat /etc/services | grep rsync
The first thing is to make sure that ssh connection is working smoothly. You can check this via "sudo ssh -vvv cnssbldsw#hydwclnxbld4" (please post the message). In advance, If you are to receive any messages such as "ssh: connect to host hydwclnxbld4 port 22: Connection refused", the issue is with the openssh-server (not being installed or a broken package). Let's see what you get you get for the first command
I am trying to run a shell script to execute a binary on a remote linux box. Both the binary and the shell script are on my local window machine. Is there any way through which i can run the binary to the remote machine directly from windows through command line tools like PLINK?
I don't want to put the binary and the script to all the remote linux boxes which
i want them to run on,Instead I want to run the shell script which will intern invoke the binary and do the desirable functions directly through my local machine.
You can run the shell script remotely, just by piping it through ssh:
cat my_script.sh | ssh -T my_server
(Or whatever the windows/plink equivalent is.)
However, you can't run the binary remotely through a pipe, the file will have to exist on the remote server. You can do this by pushing the file from your windows machine to a known location on the remote server, and then editing your script to expect the file to exist in that location:
scp my_binary my_server:/tmp
cat my_script.sh | ssh -T my_server
And then just have your script run that binary:
/tmp/my_binary
Or you can write the script so that it pulls the binary file from a central location where you're hosting it:
wget -O /tmp/my_binary http://my_fileserver/my_binary
/tmp/my_binary
Note, if the shell script doesn't do anything else besides invoke the binary, then you don't need it. You can just fire the commands directly through ssh:
ssh -T my_server "cd /tmp && wget http://my_fileserver/my_binary && ./my_binary"
You will have to copy the binary to the remote Linux box before it can be executed. However, you could have a script on the windows machine that uses sftp to transfer the binary program to a temporary directory under /tmp before running it, so there is no manual setup required.
I'm running the following command (where variables have valid values for ssh command and $file - is a .sql file).
nohup ssh -qn ${ssh_user}#${dbs} "sqlplus $dbuser/${dbpswd}#${dbname} <<ENDSQL | tee "${sql_run_output_file}".ssh.log
set echo off
set echo on
set timing on
set time on
set serveroutput on size 1000000
#${file}
ENDSQL

When I was using the above command without "nohup" before ssh command, after 1 hour or so, my connection from source server (where im running ssh) was getting an error/message "Connection reset...." and hanging my BASH shell script (which contains this ssh command in it). When, I use nohup, i dont see the connection issue.
Here's what I'm trying to get and need your help.
Change the command shown above so that the command will NOT create a nohup.out
(Did I read that I can use > instead of | tee ... and use 2>&1)
I DO NOT want to run the command giving a "&" (background)
I DO want a LOG file for the sqlplus session that's running on the target DB server via ssh command/connection (initiated from source server).
Thanks.
You can still lose the connection when running ssh under nohup, so it's not really a good solution. If possible, I would recommend that you copy the sql file via scp to the target server, then ssh in to the server, open a screen and run the command from there (Or run it under nohup). Is that an option?
I'm new to unix. I need to copy file over ssh. This is what I do
me#localhost ~ $ ssh you#remotehost
Then I established ssh so I get
you#remotehost ~ $
I'd like to use scp to copy files from localhost to remotehost. Once I have ssh connection, how do I change to prompt back to me#localhost so that I can use the scp command? Is there a command for that?
Edit: The reason I need the ssh is because after I copied the file I have to execute it. Is there a way to remain in the ssh session and use scp to copy the file that I'm editing at localhost
You do not have to first create an SSH connection to use SCP. Simply use the scp command from your shell, and it will connect to the other server.
Most shells exit with exit. CtrlD may also work.
You can also:
scp /path/to/local-file you#remotehost:/remote/path
Try screen command.
You can use scp on either side. Here are two examples:
If you are on your local host:
scp myfile you#remotehost:
If you are on the remote host:
scp you#<localhost's hostname>:myfile .
Substitute your localhost's hostname for <localhost's hostname> in the second command. If you are behind a router, it will be easier to use the first one.
Both assume that myfile is in the home directory on localhost and is being sent to the home directory on remotehost.
