Re: Expect scripting error

Hi Scott,
Thanks for mentioning the ln. Too many thing I could potentially do that get
people ticked off around here. Me guessing at an appropriate LN would be one
of those, if something else quit working around midnight.....

Here is some of stderr:

executing commands from command file /tmp/escandatasystems.scr
parent: waiting for sync byte
parent: telling child to go ahead
parent: now unsynchronized from child
spawn: returns {540}

expect: does "" (spawn_id exp3) match glob pattern "password:"? no

expect: does "Connecting to " (spawn_id exp3) match glob pattern "passwo

expect: does "Connecting to xxxxx.com" (spawn_id exp3) match

expect: does "Connecting to xxxxx.com...\r\n" (spawn_id exp3)
expect: timed out


I just checked again with Cygwin, end of the password prompt is password: - so
is the script mistimed where it reports 'no'? I can sign on with Cygwin, so
the account has not been locked. But, I don't see anything other than:

Connecting to xxxxx.com
xxx's password:

Am I invoking it correctly with:

===> call qp2shell parm('/usr/local/bin/expect' '-df' '/tmp/xxxxx.scr')

Looks like what you have in your article to me.

Hi John,

The stty errors are because Expect wants the stty program to be in the
/usr/local/bin directory, whereas in PASE it's located in
/qopensys/usr/bin. You can solve the problem by doing (from PASE):

ln -s /QOpenSys/QIBM/ProdData/OS400/PASE/bin/stty /usr/local/bin/stty

That'll set up /usr/local/bin/stty as an alias, so Expect can use it.

The pattern not matching isn't really a problem. When you tell Expect
to show you diagnostics, it'll show you all of the lines that it
processes that do not match your string. It says that "" (a blank line)
doesn't match "password:" which is normal -- it shouldn't match. The
line following the blank line might have "password:" or maybe the one
after it. It's not a problem unless NOTHING matches...

Please fix the stty thing, and then maybe the log will make more sense...

Following Scott' examples, I have been trying to get a script to connect to a
remote site for sftp. It isn't working right, but, at least, it is not locking
up the remote system either.

First, from working with scripting in the past, I assumed that the search
pattern does not have to be the entire string. In this case, the remote site
sends back a rather long user name, followed by 's password:. I have tried
running this with the entire user name as well as just password:.

I get the same error each time. My first thought is that something else is
missing.

Anyway, this is what I receive in stderr:

spawn: returns {494}

expect: does "" (spawn_id exp3) match glob pattern "password:"? no

expect: does "sh: /usr/local/bin/stty: not found.\r\n" (spawn_id ex

expect: does "sh: /usr/local/bin/stty: not found.\r\nConnecting to

expect: does "sh: /usr/local/bin/stty: not found.\r\nConnecting to

expect: does "sh: /usr/local/bin/stty: not found.\r\nConnecting to
expect: timed out

My questions:
1) I have logged in manually, and I can confirm that the trainilg part of the
password prompt is indeed password:. So what is the expect trying to tell me
when it tates that the pattern does not match?

2) Notice a little further down the not found related to /usr/local/bin/stty? I
have Cygwin on my desktop. Looking for stty, it is in /usr/bin. But, even
looking there on the i, I do not see it.

Any thoughts?

Thanks.
