    How to run Putty session with Plink from VBA macro

    I am trying to automate an ssh session by starting a putty session using plink.exe from a VBA macro. Part of the automation is sending some commands to a linux server. After I run the macro; plink opens in a blank command prompt window but closes a few seconds later . This is the line that attempts to run plink.exe
    Set oExec = WshShell.exec("plink.exe -load aaTest")
    . I suspected originally that it might be improper string formatting. However, when I try to run the putty gui from the same macro by replacing the above line with
    Set oExec = WshShell.exec("putty.exe -load aaTest")
    , the putty gui opens and I can login. The StdIn.Write code doesn't work and that is because putty doesn't use StdIn. But I don't get why plink isn't working. What am I doing wrong here?

    Here is the complete macro:

    Sub AutoMop()
    ' AutoMop Macro
    Set WshShell = VBA.CreateObject("WScript.Shell")
    WshShell.CurrentDirectory = ("C:\Users\lxp\Core\91CS\PuTTY")
    Set oExec = WshShell.exec("plink.exe -load aaTest")
    ' Write to the input stream
    oExec.StdIn.Write "service ssh status" & vbCrLf
    'Application.Wait (Now + TimeValue("0:00:00:05"))
    oExec.StdIn.Write "sudo service ssh restart" & vbCrLf
    End Sub
