How to write a telnet VI with automatic login?

[atd]

Hi,

I'm new to Labview and working on a labview program to automate power measurement.  This program requires a login to a linux host system and run a few linux commands to configure the system undertest.  All of these info (username, password, linux commands, etc) are fed from another VI automatically.  I bought the Internet toolkit, but is still unsuccessfully figure out how to write it.  Could someone show me an example on how to write an automatic login/pass and perform an "ls" command?

You should be able to use the telnet play script for this.

Also look at the telnet line client example shipped with the toolkit.

Note that the prompt and replay strings have the / mode switched on to make sure \r\n is carriage-return,line-feed.

This should get you started

Thanks David, it works for me finally  However, the Telnet Play Script.vi took a long time to execute.  I did some debug and found out that the Telnet Write.vi inside the Play Script.vi hold every execution (each data in entry) for at least 7-10 seconds.  I could not see any delay programmed in the Telnet Write itself and it worked normally when I tested outside of this Play Script.vi.  Does anyone have any idea?

After some debugging, it turns out that the timeout input is always overwrited by the program default of 25 secs.  I cloned and modified the Telnet Play Scirpt.vi so that when a command expected to take a longer time, it will be routed to a wait frame.  With this case structure select, the program can be fine tuned for speed depending on command run.
