I'm using the remote development feature of pycharm, and I have successfully connected and am able to do changes to the files, but when I open the terminal I get this error :
you have no permission to access the terminal. to execute commands request the full access permission from the host
Notes
The server is ubuntu 16 Linux

STAF/STAX application works in a way that if the staf service is running in a windows machine then from a linux machine where staf is configured and if both the windows machine and linux machine are communicating each other then from linux machine by using staf we can execute commands in windows machine without passing any credentials but there is a shared folder which is accessible from windows machine but when trying from linux machine it is saying "Access is denied". in order to grant access from windows machine a user need to created and the user is also created but how to pass that user credentials to authenticate with that windows machine and access the shared folder using IBM STAF application.
this is working
/usr/local/staf/bin/staf process start shell command "ipconfig" WAIT STDERRTOSTDOUT RETURNSTDOUT
this is not working
/usr/local/staf/bin/staf process start shell command "copy "/shared_path_folder/file.txt" "/destination_path/file.txt"" WAIT STDERRTOSTDOUT RETURNSTDOUT
I am using Mininet on a remote Ubuntu without GUI. And I am trying to use "xterm h1" to open a terminal on a virtual host in Mininet. But it showed me always there is no display connected. I am trying to use other X application like firefox and it showed me
"No protocol specified
Unable to init server: Could not connect: Connection refused
Error: cannot open display: :0.0"
Then I have set X11forward yes in sshd_config on the remote Ubuntu, and install Xlaunch on my windows but showed no changes.
Can someone tell me how to solve this problem?
PS. I am using a pycharm on Windows11 to establish this SSH session
Since you are running windows you will first need an application that will run an X11 server on your windows, Xming, for example. You will then need to configure your ssh connection to use that xserver. Finally you want to setup the DISPLAY variable at your remote to be LOCAL_IP:0 where LOCAL_IP is the public IP of your machine.
I have a file called test1.zip in /mnt/c/Users/test/ folder of my local laptop [in which ubuntu windows subsystem for linux is installed]. Local ubuntu terminal WSL name is lauda
Now, I would like to transfer this zip file called test1.zip to my remote server named stuff.
PLEASE NOTE THAT ALL COMMANDS ARE TRIED FROM MY LOCAL LAPTOP WSL SCREEN [ubuntu screen]
So, I tried the below command from my WSL [local laptop ubuntu WSL terminal]
scp user1#lauda:/mnt/c/Users/test/test1.zip user1#stuff:/home/test/codes/test1
and got the error ssh: Could not resolve hostname lauda: Name or service not known
So I tried the below [replacing the lauda local laptop ubuntu terminal hostname with its IP]
scp user1#172.xx.xxx.xxx:/mnt/c/Users/test/test1.zip user1#stuff:/home/test/codes/test1
this resulted in error as ssh: connect to host 172.xx.xxx.xxx port 22: Connection refused
Now I tried the same command as above but in opposite way as shown below
scp user1#stuff:/home/test/codes/ user1#lauda:/mnt/c/Users/test/test1.zip
and got the below error
ssh: Could not resolve hostname lauda: Temporary failure in name resolution
Later, I tried with IP address
scp user1#stuff:/home/test/codes/ user1#172.xx.xxx.xxx:/mnt/c/Users/test/test1.zip
And I got the below error
ssh: connect to host 172.xx.xxx.xxx port 22: No route to host lost connection
Later, I tried the below commands as well
scp /mnt/c/Users/test/test1.zip user1#stuff:/home/test/codes/
and got an error scp: /home/test/codes/test1.zip: Permission denied
So, I again tried like below
scp user1#stuff:/home/test/codes/ /mnt/c/Users/test/test1.zip
and got an error scp: /home/test/codes: not a regular file
PLEASE NOTE THAT ALL COMMANDS ARE TRIED FROM MY LOCAL LAPTOP WSL SCREEN [ubuntu screen]
How can I transfer local files/folders from my local ubuntu WSL terminal to remote server?
scp /mnt/c/Users/test/test1.zip user1#stuff:/home/test/codes/ is the closest attempt to working. The error you get could be due to one of two reasons:
Firstly user1 does not have permissions to write to /home/test on stuff - makes sense as usually only the test user would be able to write there. (Note that the test user on your WSL instance is not the same profile the test user on the remote.)
Secondly the /home/test/codes/ folder may not even exist yet.
Instead (if you know test's password) copy as the test user :
scp /mnt/c/Users/test/test1.zip test#stuff:/home/test/codes/
Or copy to user1's home directory (after ensuring you have created /home/user1/codes/
scp /mnt/c/Users/test/test1.zip user1#stuff:/home/user1/codes/
I have followed the instructions here:
(including the paramiko packgage).
The putty connection works.
I have also downloaded the kernel .json file from the VM.
Into Spyder I go:
Consoles / Connect to existing kernel
Point toward the .json file (located in the local /jupyter/runtime folder)
Check this is a remote kernel
username#location:port (same as in Putty connection)
Enter the remote user password
Ok ...
Connecting to kernel ....
Appears in the Ipython console. And spins and spins. No timeout, nothing.
I have an application which executes on a remote Linux system. How can I add this application to startup of that remote system from my local linux system. I know the path of executable (application) on remote system.
I searched a lot on different sources but didnt get any idea ?
Edit: What am I doing is:
I have developed a desktop-application (using qt).
I have loaded this application on remote system (using libssh).
I am able to execute this application remotely.
Now, I want to add this application to startup of that system remotely (stucked here).
Any Idea how to complete 4th step ??
Create Executable.desktop file (on local machine)
Open ssh connection and get remote machine root access
Copy this Executable.desktop file to "etc/xdg/autostart" on remote system (using ssh and commonds )
Reboot the remote system (using ssh and commonds )
Note: The solution will work if we know the location of executable/application on remote system
