MATLAB: Run telnet with cmd in MATLAB command window

cmdMATLABtelnet

Hey, I have some trouble with using the command interface in MATLAB.

When I run system('cmd'), the command prompt starts and is displayed in the matlab command window. When I now type telnet at the cursor position in my matlab command window, it does not know the command 'telnet'. When I start telnet in the normal windows command window without any matlab stuff, everything works fine with that command.

What can be wrong with that?

Thanks, Martin

I think I figured out what is going on. The "telnet" client seems to set up some sort of terminal environment, which doesn't play well with the way that the MATLAB command window is working. If I try the following, nothing useful happens.

>> system('cmd')
Microsoft Windows [Version 6.1.7600]

c:\Temp>telnet
telnet

If I get what you are trying to do, I believe you need to use the "plink" command, which is part of the PuTTY suite, which is freely available (google "download putty"). When I use that, I get a usable prompt:

>> system('cmd')
Microsoft Windows [Version 6.1.7600] 
Copyright (c) 2009 Microsoft Corporation.  All rights reserved. 
c:\Temp>"c:\program files (x86)\putty\plink.exe" -telnet myunixhost
"c:\program files (x86)\putty\plink.exe" -telnet myunixhost
myunixhost login: <enter my login here>
Password: <enter password>

If you are having trouble scrolling, one solution would be to set the terminal type to be something "less powerful" than a vt100. For example, in csh:

setenv TERM dumb

or in Bourne shell

export TERM=dumb

before running MATLAB.

Another solution may be to use another tool like an SSH client or to use VNC.

Putty is one ssh client that is available for Windows. VNC is another option to use instead of Windows telnet to connect to the UNIX machine.

MATLAB: How to get the process ID of the current MATLAB session in MATLAB 7.5 (R2007b)

While there is no single command in MATLAB that can obtain the process ID of the current session of MATLAB, to achieve this you can use the shell commands TASKLIST and PSLIST.

The MATLAB central files located in the following section, use the above shell commands to yield the current lists of tasks running on a machine :

https://www.mathworks.com/matlabcentral/fileexchange/9976-tasklist-pslist

You can download the above files, and use them in the following way from within MATLAB to obtain the process ID's of all the current MATLAB sessions:

1) Windows XP:

s = tasklist;
for i = 1:size(s,2)
    cmp(i) = strcmp(s(1,i).name,'MATLAB.exe');
end
mpid = s(find(cmp==1)).pid

2) Windows (NT and higher) and LINUX:

s = pslist('MATLAB.EXE')
mpid = s.pid

Note that to use the PSLIST command in Windows, you need to download pslist.exe, which is a freeware.
