Title: telnet
Post by: bugouzhi on November 12, 2004, 01:39:18 pm

Hi all:
I am trying to do a automated telneting to some localhost on the zaurus, does anyone have any idea how to do this?
I've tried the following simple script that seems to works on other linux:
in a script telnet.sh:
sleep 1
echo <username>
sleep 1
echo <password>
sleep 1
echo <command>

then on the terminal:
./telnet.sh | telnet localhost <port>

but zaurus just seems to do anything after i execute the above command,
no return at all.  Does anyone have any ideas, or any other way to do this.

Thanks a lot.

Is telnetd running? Can you manually telnet to the Zaurus?

yes the telnet server is running all right,
i can manually telnet to the localhost with no trouble.
It seems telnet is closing stdin and not accepting anything
that is sent through the pipe..
Anyone has any ideas??


Thanks

I don't think you can do this with telnet.

Try openshh with key files for auto login (more secure than telnet and offers more bells and whistles too). I have ssh set up on my pc and the Z and with ssh-agent I only have enter the password when I first login to my desktop after that I can ssh to the Z without entering anything - great for automated rsync backups

ps: the script has some potential for errors "$IN" should be protected like "x$IN" etc.
pps: yes, ssh *is* the way to do this.
