Re: how to get source ip of a telnet session

[Harold L Hunt II <huntharo at msu dot edu>]

Any reason you can't grep the output of tlntadmn to get what you need?

By the way, when I run tlntadmn /? I get:

C:\Documents and Settings\harold>tlntadmn /?

Usage: tlntadmn [computer name] [common_options] start | stop | pause | 
continue
 | -s | -k | -m | config config_options
                           Use 'all' for all sessions.
     -s sessionid          List information about the session.
     -k sessionid          Terminate a session.
     -m sessionid          Send message to a session.

     config                Configure telnet server parameters.

common_options are:
     -u user               Identity of the user whose credentials are 
to be used

     -p password           Password of the user

config_options are:
    dom = domain           Set the default domain for user names
    ctrlakeymap = yes|no   Set the mapping of the ALT key
    timeout = hh:mm:ss     Set the Idle Session Timeout
    timeoutactive = yes|no Enable idle session timeout.
    maxfail = attempts     Set the maximum number of login failure attempts
                           before disconnecting.
    maxconn = connections  Set the maximum number of connections.
    port = number          Set the telnet port.
    sec = [+/-]NTLM [+/-]passwd
                           Set the authentication mechanism
    mode = console|stream  Specify the mode of operation.

So, what do you mean when you say it does not seem to accept arguments?
