I use pscp to copy a file from Windows to Unix and I run it using VBA.
After pscp command how will I ensure that file is transferred successfully?
shell "pscp -P 22 -pw abcd test.csv user#XXX.com:/u01/test"
Test pscp exit code. 0 is success, 1 is error.
For examples of code that test exit code of an application, see:

I have hard requirement of logging into a terminal via SSH from TCL console and relaunch a tcl script from that terminal. For this I use exec command and it does get executed. The only problem is it doesn't return back to parent code.
I have automated SSH login and it works fine from a bash/csh terminal
But from TCL console, the following happens
Simple example
exec ssh hostname pwd
puts "Done"
When I execute this code in TCL, "Done" never gets printed. I just get the output of pwd and that's it.
I have a need of looping SSH into multiple terminals and run TCL jobs on a hardware, but the loop gets stuck after executing the first SSH.
I search the internet for answers and I am not able to find any. Please help.
There could be a lot issues going on here. Running ssh with an explicit command (pwd) will usually default to not allocating a tty (ssh -T) and will run the remote shell in non-interactive mode. And the output of a command called from exec is not normally echoed to standard output, so I would not expect you to see the output if you call it from a script. You have to print the result of exec to see the output of the pwd command. Also, different shell startup scripts are run on the remote host depending on which shell the account is set up with and whether it is an interactive or non-interactive shell. It could be .bashrc, .bash_profile, .profile, .cshrc, etc., and if the script behaves differently when it has a tty vs. when it doesn't, that could explain differing behavior between a bash/csh shell and the TCL console.
Without having access to your system, it is hard for me to troubleshoot. I would start with a script like this:
set result [exec ssh -T hostname pwd]
puts "result = $result"
puts "Done."
Then I would try changing the -T to a -t and trying again. If the output of "pwd" is appearing before the "result =" line, then you can tell that the command is writing the result to a tty instead of standard output, and that's useful information for troubleshooting.
I just wanted to automate the file transfers without opening WinSCP, through script.
Up to some extent I performed the file transfer operation except PuTTY session.
I prepared a sftprun.cmd batch file like:
D:\winscp\winscp.com /script=D:\winscp_auto\sftpscriptJAC.txt
Can you please suggest me to open PuTTY through above mentioned script to execute command on the server?
mount -o remount,rw /
The putty details should be provided under the script file "sftpscriptJAC".
WinSCP can execute remote commands on its own from the script (with some limitations), using the call command:
open sftp://user#example.com/
put C:\file.txt
call mount -o remount,rw /
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 have a linux shell script file which collects various data from linux server. (Services, Process, FreeSpace etc.).
From windows to collect the data we are using Plink to connect to linux Boxes and run the shell script
plink root#servername -pw Password -noagent -m Batch-File.
and using pscp to copy the file to windows location.
Now when I try to do the same for Esxi the plink command fails with the error below.
FATAL ERROR: Server unexpectedly closed network connection
though If i give a direct command as below.
plink root#servername -pw Password -noagent ls /etc
works out.
Let me know how to use the plink for esxi .. if possible.
After seeing the messages log it looks like that the issue is with esxi's limitation to read long character string. The message log fails in the session with String Too Long and then post a message of closing the connection.
Thus the approach was to copy the shell script as a pscp connection, run the file with executable permission and collect the data gathered and delete the file from system.
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
