Run ssh command in labview

does anyone knows how to run an ssh command in labview?
I know how to run some linux commands in labview but my problem is when I try to run an ssh command ...

Unfortunetly, I don't know how to script in a password for ssh. SSH closes the stdin and re-opens the tty that you are logged in at. This is actually a security feature. As well as a way to send stdin to remote programs (otherwise your password would get in the way.)
If you don't need to ssh to a remote host, and you want to chmod something on the localhost, you could use sudo instead. With sudo you can specify certain users (or all users) to run certain commands. (so you could make a shell script to chmod for you).
I don't know your exact needs, but I think that a public/private keypair could still work. In your authorized keys file on your "root" account, you can even specify that "this public key does not get shell access, and can only execu
te this one command." This would probably be the most secure method. But it requires the user to have the correct private key as well.
If you know that won't work for some reason, then maybe you could setup a inetd process that will execute a command whenever someone connects to a certain port (then you could use LabVIEW's TCP VIs).
Or, if you are not connecting remotely, you could setuid your LabVIEW executable (A VERY BAD IDEA!).
Also, it is possible to script "telnet." It would of course transmit your root password as plaintext, but trying to script your ssh session would also embed your password in your LabVIEW VI. Out internet toolkit for LabVIEW has some helpful telnet VIs.
May I ask why you want to chmod something on a remote system that requires root? Sounds like maybe you should create a LabVIEW application on the remote side that acts as a daemon (running as root) and accepts connections and commands and does the chmodding for you.

Running ssh command from java and then answering password prompt

Hi,
I have a situation that has not solved yet. I am running ssh command from unix terminal without any problem, and then i enter password.
For example :
[oracle@fuata]:/export/home/oracle> ssh -N [email protected] -L 9901:127.0.0.1:9999
Password:
It is working. I have question that how can i perform this in java? I am thinking that i can run ssh command by using Runtime Class, it is ok. But how can i answer the password? I am a bit confused. Is there any example looks like this?
Thanks for responses.

Thanx. Firstly i insisted to do this without jsch but actually this is harder than jsch. I edit some of code pieces PortForwardingL.java and could run it. It works problem-free. Could you say why you "insisted" on this approach. It can't be for speed+ since jsch is very fast. It can't be for portability+ since jsch is portable but the use of Runtime.exec() requires the installation of ssh software. It can't be because of limitations+ since jsch is a fully featured library. It can't be for security+ since jsch is secure.

Total nube to jws, need to run ssh command via web or jws?

Ok So we had a developer that created this application that can basically run ssh commands via jws I believe. Unfortunately he is no longer here. I am wondering how you do this? I know tha commands that are already set up, but I have no idea how to implement it into my project.
I am using Struts 2, Java 5, Weblogic 9.2, Spring
Thanks

Have a look at:
http://www.jcraft.com/jsch/
basically you'd need a small webstart client to wrap something like the above library. Best thing is to try with a standalone java client first. Once that is working have a look at turning it into a webstart app.

Running ssh command in a java application

Hi there!
I am trying to run a ssh command from a java application cause I need to store the result.
Actually I can run this command in the cygwin shell so I need to open the shell and run the command, all trough java.
so, what my process needs to do is:
1) open the cmd
2) run C:\cygwin\cygwin.bat
3) execute the ssh command
ssh -l fip-user ipdb fip 42704) print the result of the ssh command.
Note that the cygwin opens in the same command line window and so will print it's result to the same process inputstream

Use "Runtime.getRuntime().exec()" to execute the SSH program,
and you can then get the output of the SSH program
via the getInputStream() method on the returned Process object.
Note: there are many pitfalls with this. In particular, most people don't know
they should create separate threads to drain the input/output pipes.
See this excellent classic article http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
on how to do it right.

Running SSH command after auth

To save some time, I know about sshrc...
What I am trying to do is run a script (or file or whatever) after a user is authenticated... This is extremely simple with the use of sshrc, but my users are going to be connecting with the -N argument:
-N Do not execute a remote command. This is useful for just forwarding ports (protocol version 2 only).
When users are connecting with that, my script does not run...
Is there an alternate way to run a script?
By the way... The reason I'm doing this is because I am running a SOCKS server and the users are set to /bin/false.

Well I am trying to run a script after ssh authentication when the client is connecting with the -N flag....
I am hosting a socks proxy server, and I want to prevent simultaneous logins with the same user. The proxy users all have the shell set to /bin/false and their default group set to 'proxy '.
Basically, what I want to do is to disconnect both connections when I detect simultaneous logins...

This means that the SSH server you're trying to connect to isn't listening. Is the SSH server running? Are you trying to connect to the right machine?

My process interrupts when I hibernate while running SSH, what to do?

Hi!
I have a low-end box (512 MB RAM, 1 processor, 15 GB hard disk, 2 TB / month bandwith, Arch Linux) , and I connect to it by SSH. Currently I use it for uploading / downloading stuff, and video encoding. My problem is when I transcode the video by FFmpeg - it takes long time, about 8 hours - and when I hibernate my home machine, the FFmpeg process aborts on the remote box and the resulting video file will be truncated. What can I do to avoid this annoyance?

When your client hibernates, the ssh connection times out and the remote's ssh client session is terminated. This sends a SIGHUP to all the child processes, to which the default reaction is termination. The 2 most common ways to deal with this are either the 'nohup' command (`man 1 nohup`) (which I personally dislike and try to avoid because its default behavior is to send stdout/err to 'nohup.out'), or running the commands in a tmux/screen session, which is something you should learn/know about either way. The moment you start using ssh is the moment you lose every right to argue against screen/tmux (even for local work they're perfectly useful tools)
My personal favourite is tmux.

Running ssh from within java program

Hi!
I am trying to start ssh from within java e.g.:
Runtime run = Runtime.getRuntime();
Process pro = run.exec("ssh -l xx 12.12.12.12");
But it complains:
socket: Operation not permitted
ssh: connect to host 12.12.12.12 port 22: Operation not permitted
Running ssh from the command prompt works just fine. It's run on win xp.
What is the problem, and how can I avoid it?

Afraid not. I think maybe it's related to security permissions, but I am really not sure. If you can help, I would appreciate it.

Hi,
I am not familiar with Java setting in Oracle
I have a a stored procedure that call a java program to execute host command like
ssh user1@localhost '/home/user1/someprogram'
if we execute this directly using PuTTY
we can do the following with no problem
su - oracle
ssh user1@localhost '/home/user1/someprogram'
but when we execute the stored procedure,
we have to do
*/usr/bin/ssh* user1@localhost '/home/user1/someprogram'
does anybody where to set the path or environment to make the java know the path correctly.
thanks
ps:. this is happen after we recently upgraded our Oracle from 9.2.0.8 to 11.1.0.6

Mac os X - ssh command

I am trying to build a little applications and want to be able to use the unix shell to run ssh
so i can run the ssh command and read and write to the connection.
I tried to use the Runtime with the exec command but i get an error saying ssh is unknown command, but i can use commands like "ls" and get the output
any ideas?
cheers

If you're at a terminal window and you can type ssh and it works, then ssh is in your PATH. However, the environment you get when you use Runtime.exec is not the same as in a terminal window. It won't have run all the .zshrc, etc. files that you get with the terminal, so the PATH is different.
You'll need to either specify the full path, like runtime.exec("/usr/bin/sss blah") or else exec a shell script that sources the proper .zshrc or whatever files.
Note, however, that you still might have problems. ssh might be one of those programs that only accepts input from a terminal, not from arbitrary pipes or streams.

Cannot start NodeManager Remotly (Via SSH Commands)

Hi all,
we are going to start the node manager of one of the cluster servers via SSH command.
But it is not starting. We can start it directly by log in to that server and run startNodemanager.sh script.
What is the issue?
Thanks,
Nir

Hi are you able to start Node manager using following WLST Command :
startNodeManager(verbos='true',NodeManagerHome='$WL_HOME/common/nodemanager',ListenPort='<PortNo>',ListenAddress='<HostName')
And also can check NodeManager Log files for errors .

SSH + Command + Quit?

I am writing a shell script to ssh to a range of laptops/desktop and run some commands which is easy enough:
ssh -l USER 1.2.3.4 echo "hello world"
But if I run a command that takes a while to run, for example "softwareupdate -i -a" to download and install all software updates, I have to wait for the update process to complete before my machine will ssh to the next laptop/computer and run my chosen command.
How can I ssh to a computer, send it a command and then disconnect not having to wait for the command to finished executing, just let it run?

If the destination host is a Unix machine, won't adding an & at the end of the command string work? This should normally send the command to be executed in the background, disconnecting from the control terminal.

-bash: ssh: command not found = no ssh?

Hi all,
Sorry if this isn't the right category - this seemed to be the best fit.
I'm having trouble with SSH.
I've used ssh in the past (back when I was running Leopard) but I've never had all that much use for it. Today, however, I opened up terminal to SSH to an iMac on my local network, and got the following back:
-bash: ssh: command not found
Having a look around on the internet, somebody else said that they got this message but was still able to see the SSH manual by typing ssh man. However, when I tried this I just got "command not found" again.
Any ideas?
Thanks in advance,
BrutalSpoon.

Do you remember if you modified .profile or .bash_profile when you installed mysql?
I guess you could search for the file that has the modification
/usr/bin/grep /usr/local/mysql/bin $HOME/.[a-z]*
Once you find the file, edit that file and put a dollar sign infront of PATH
/usr/bin/nano /name/of/file/with/mysql/bin/in/it
The entry you want to fix most likely looks like
export PATH=PATH:/usr/local/mysql/bin
you want to change this to
export PATH=$PATH:/usr/local/mysql/bin
The problem is the missing dollar sign $ which would cause the current PATH to be substituted before the addition of /usr/local/mysql/bin.
Once the change is made, quit Terminal and relaunch it. The corrected PATH should now work.
NOTE: If you do not want to use nano you could use TextWrangler (via File -> Open Hidden...), or Smultron (via File -> Open Hidden...). You should be able to find these GUI based text editors via <http://versiontracker.com>.
Good luck.

Urgent!! running system command in java

i am trying to run system command(windows) in java. I am getting
exception as java.io.IOException: CreateProcess: c:\dir
Please Help.
Here is the code
import java.io.*;
public class RunCommand {
public static void main(String[] args) {
try
//run dir command
Process p = Runtime.getRuntime().exec("c:\\dir");
BufferedReader stdInput=new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError =new BufferedReader(new
InputStreamReader(p.getErrorStream()));
//read the output
System.out.println("here is the output:\n");
while((s=stdInput.readLine())!=null){
System.out.println(s);
System.out.println("here is the error if any");
while((s=stdError.readLine())!=null){
System.out.println(s);
System.exit(0);
}//end try
catch (IOException e)
System.out.println("exception Happened" );
e.printStackTrace();
System.exit(-1);

It works fine if you replaceProcess p = Runtime.getRuntime().exec("c:\\dir");withProcess p = Runtime.getRuntime().exec("cmd /c dir");And don't forget to define your s variable.
