Hi.

Use "$STDERR_MERGED" instead of "$STDERR_CHILD + $STDOUT_CHILD"

 

$DOS = Run(@ComSpec & " /c telnet india.colorado.edu 13", "", @SW_SHOW,$STDERR_MERGED)

Help files:

[optional] Controls various options related to how the parent and child process interact.
    $STDIN_CHILD (0x1) = Provide a handle to the child's STDIN stream
    $STDOUT_CHILD (0x2) = Provide a handle to the child's STDOUT stream
    $STDERR_CHILD (0x4) = Provide a handle to the child's STDERR stream
    $STDERR_MERGED (0x8) = Provides ***the same handle for STDOUT and STDERR***. Implies both $STDOUT_CHILD and $STDERR_CHILD.

Regards, Rudi.

Hello prayags,

please reply in the thread, not as a PM (except explicitely asked to do so)

 

hi Rudi,

thanks for the reply,

but i am not getting any output. 

i tried by manually disable the telnet service from Windows Add/Remove components


i need to check whether the telnet service is enabled or no in a system with windows 7 OS

 

Check for "telnet.exe" in the folder "C:\windows\system32"

 

If your compile your script for x86, use envget("sysnative") instead of @SystemDir, as @SystemDir then will point you to @SystemDir = C:\Windows\SysWOW64 when compiled for x86 on a x64 Windows PC.

 

When $STDERR_MERGED is used, you won't see any output in the CMD box. You will have to read it, as you speicfied above:
 

ProcessWaitClose($DOS)
Sleep(2000)
$Message = StdoutRead($DOS)

 

Try  option /k instead of /c and see, if you get any output there:

runwait(@ComSpec & " /K telnet india.colorado.edu 13")

 

 

Regards, Rudi.

hi,

Thanks for the help.

i am creating a tool which will distribute within teammates with their own workstations

1. first ping to server in the dropdown list

2. if ping successful , will check whether telnet service is enabled or no. and then login to server via telnet with username and password

( i was using cmd output to txt. it works fine for workstations having Telnet feature enabled. but my code does't work in workstations having telnet feature disabled.)

so i need help to capture any error like 'telnet' is not recognized as an internal or external command. before login to server if telnet featureis disabled

[prayags]

Thanks rudi, for the Help !

as said by you i will Check for "telnet.exe" in the folder "C:\windows\system32", if not found My Tool will exit

 

[rudi]

Hi again.

 

You also can use Fileinstall() to force a copy or telnet.exe e.g. to @TEMPDIR

 

Regards, Rudi.

[prayags]

but do i have to keep telnet.exe everytime attached with my tool. can you pl help me with the script

 

[TheDcoder]

telnet is not installed by default, you have to install it manually... btw, I don't suggest using FileInstall on telnet.exe because there *might* be restrictions which don't allow redistribution of telnet.exe

[prayags]

hi TheDcoder,

you are right , the workstations which we are using are administrator Controlled systems. we cannot install anything without the administrator rights.

pl help another way around or i can use  Check method for "telnet.exe" in the folder "C:\windows\system32"

 

[rudi]

Hi.

You can use a 32-bit version of an "equal old or older" Win-Version and fileinstall that one to @tempdir and run it from there.

You also can use putty.exe (fileinstall() as well) with the command line switches to make it use TELNET communication type.

 

Regards, Rudi.
