It is right?

Script:

Telnet ip-address
sleep 5
echo username
sleep 5
echo password

I try this, but it isn't work. Please help

There a way to do it this way, check http://steve-parker.org/sh/expect.shtml

But, you'll find that Expect is really what you need, if rsh (or ssh) won't be satisfactory (why ??).

Ant (what make is for C, ant is for Java) has also telnet scripting capabilities).

Cheers

If you are familiar with "perl", you can drive a telnet session with "Net::Telnet" module. Example-

use Net::Telnet ();
$t = new Net::Telnet (Timeout => 10,
Prompt => '/bash\$ $/');
$t->open("sparky");
$t->login($username, $passwd);
@lines = $t->cmd("/usr/bin/who");
print @lines;
