Hi,
Okay - there is likely an easy answer to this but I'm a bit lost at the
moment.

I have a requirement to do some testing which needs many rlogin's - I want
to have these
automated in a script as the testing is for me there is no security risk.
How do I pass the password etc at an appropriate time for the rlogin
command?
I will also need to do the same with telnet....


Thanks,
Jon

Hi,

If you have 'expect' installed you pass the password thru expect.

if not , consider remsh.

thanks

You could use C-Kermit:

http://www.columbia.edu/kermit/ckermit.html

which is an Rlogin client and a Telnet client (among other things) and
which includes its own built-in scripting language:

http://www.columbia.edu/kermit/ckscripts.html

The only trouble is that rlogin is a privileged port; you have to be
root to use it, or else the rlogin application has to be setuid root,
but Kermit can't be setuid root because it also reads and creates files.

Another possibility is SSH -- you can do that with C-Kermit too
(version 8.0 and later).

Note that C-Kermit comes as standard equipment on HP-UX, but older
HP-UX versions have older C-Kermit versions installed.

That reminds me, you can also use Kermit like expect, over the
regular rlogin client:

http://www.columbia.edu/kermit/ckermit70.html#x2.7.2

(C-Kermit 7.0 required).

Thanks for the replies - I will be investigating the use of Expect for some
testing and currently getting Tcl installed.

However, this still doesn't truly answer my question. Regardless of
user/security etc as these are not an issue I need
to test the rlogin and telnet commands - that is, I need to automate - in
a script - access to a unix box using the specific commands
of rlogin and again test using the specific command telnet. I therefore need
a way of passing user and password to these commands in a way
that one might with scripted ftp.

I understand that suggested methods are valid but not for the specific
testing that I need to do with these commands.
I am attempting to mimic a real-life situation for some software being 'hit'
by lots of 'people' either rloging or telneting into
a unix box (quotes used as I am running a lab-test rather than getting
customers to do it for real!)

I just need a simple way of scripting rlogin an telnet as they come on the
box but for some reason the way to do this seems to be lost on me.....

Thanks again,
Jon

Jon,

You need 'expect'. It will run the actual telnet or rlogin commands however
you desire to script them. Telnet is not scriptable otherwise, although it is
possible rlogin is.

If you haven't yet learned about expect, you should do some reading before
making further requests on this topic, as you have already been given the
answer more than once.

As noted previously, it depends on the application. Here is a Telnet
client that is fully scriptable:

http://www.columbia.edu/kermit/ckermit.html

(and also supports all the standard Telnet security options such as SSL/TLS,
Kerberos, etc). More info:

http://www.columbia.edu/kermit/ckututor.html Tutorial
http://www.columbia.edu/kermit/ckscripts.html Scripting tutorial + examples

Note the second link, where you can find ready-made scripts. Note also that
Kermit comes preinstalled on every HP-UX system, 10.00 and later, and is
available for every version of HP-UX back to 5.21 and forwards to 11.23:

:
In applications like Telnet and FTP, it is better to have scripting integrated
into the application where all the actions occur, for the reasons given here:

http://www.columbia.edu/kermit/ftpscripts.html

(which is about FTP scripting but applies equally to Telnet or any other
communications protocol). As noted previously C-Kermit also includes an
rlogin client, but you must be root to use it because rlogin is a privileged
port and C-Kermit can not be setuid root for reasons that are explained
elsewhere.
