Process wont run with opt_flags

Recommended Posts

Hey guys, I am trying to run a process and use the stdin, stdout, stderr streams, but when I attach the opt_flags in the run;

$TNPid = Run('C:\Windows\System32\telnet.exe', '', @SW_HIDE, $STDIN_CHILD + $STDOUT_CHILD + $STDERR_CHILD)

The process opens and closes right away, not allowing for the commands to be sent to it. But If I have the run command like this:

$TNPid = Run('C:\Windows\System32\telnet.exe', '', @SW_HIDE)

It works fine, but I have to use ControlSend commands to write, and I am unable to get the stdout and error for the process.


Any ideas as to why this is happening? Thanks.

What about?:

$TNPid = Run(@comspec & ' /c telnet.exe', '', @SW_HIDE, $STDIN_CHILD + $STDOUT_CHILD + $STDERR_CHILD)

So, I have been messing with it. When I do this: 

$TNPid = Run(@comspec & ' /k telnet.exe' , '', '', $STDIN_CHILD + $STDOUT_CHILD + $STDERR_CHILD)

I am still getting that the command prompt window is running, even with the following commands to try and get telnet to run:

StdinWrite($TNPid, "C:" & @LF)
    StdinWrite($TNPid, "cd Windows\System32" & @LF)
    StdinWrite($TNPid, "telnet.exe" & @LF)

However, When I run this:

$TNPid = Run(@comspec & ' /k telnet.exe') ;or a /c

telnet.exe opens up right away. When it comes up, it have a title of "C:\Windows\System32\cmd.exe - telnet"
