Need to send a device identifier |

Hi
I need to know if there are any way to send a device identifier (something like w1, 1 or 2234 for example) when logging onto the telnet server.
I need this device identifier to determine the screensize that the device logging on as, is using.
For instance I will have two handheld devices with different screen sizes that logs onto the telnet server. This device identifier is then passed into my console application as a parameter from the allusers.bat. the console app will then display the screen according to the device logged in.
Is this possible?

Hi,
If your devices are using static IPs you can identify them using %KTS_IP% environment variable.
Another solution is to use user name it is in %KTS_USER% variable.
Btw, if your device telnet client is smart enough it would send device screen size when initializing session. KTS will take care to resize console screen automatically, if this is the case you can directly check for console size in your app.

KTS_IP environment |

Where is this KTS_IP environment variable? I also need to find out which device is associated with a telnet session. My devices all have static IPs. Thanks.

Just expand the KTS_IP variable.
For example you can see the KTS_IP value in cmd.exe by typing
echo %KTS_IP%
this will give you the ip of the connected user.
Combining this with a little batch scripting you can start different command or supply different parameters to commands based on the device ip.

Session Identifier |

I guess my problem is that I am using only one user login to the KTS telnet server from several devices each running a telnet session (each device has a static ip). When I look at the task manager in Windows 2003 server, I see the same user with serveral instances of the application. I need to know which ip address or user is associated with each session. So if there is a way to use the %KTS_IP% variable, please give me an example. Thanks.

Since you are using one user for login you can't distinguish sessions by user name.
Here is what you can do:
1) you will need these third party tools(note openports is NOT free for commercial use)
[url=l0c41://www.diamondcs.com.au/openports/]openports.exe[/url]
[url=l0c41://www.sysinternals.com/Utilities/PsList.html]pslist.exe[/url]
2) now using openports.exe you can get the list of open connections and the process that uses the connection

term.exe [752]
TCP 192.222.235.2:8023 192.222.235.31:1036 ESTABLISHED
...
[/code:1:0a9bfd830d]
You are interested in the processes named "term.exe" these are KTS master session processes. In the sample above you have term.exe process (pid=752) connected to client with IP 192.222.235.31
3) run pslist.exe -t
this will give you tree view of running processes

you can find the above term.exe process by its pid(752), and as you see it has spawned two more programs CMD and NTVDM
