RE: expect - sometimes it runs sometimes it doesn't....

When I have a failure, below is what I get for an error.
I can't be sure, but I think the SSH handshaking takes longer than the timeout value.

spawn sftp xxx@xxxxxxxxxxx
ssh_exchange_identification: Connection closed by remote host
Connection closed

Hi Scott

I agree the environment variable is better - still, I though stderr was redirected by using 2>

I would not recommend using a redirect like > because that only
redirects "standard output" (stdout) which is where normal output

Assuming you are running this from a CL program, I would use the
QIBM_QSH_CMD_OUTPUT variable to specify a file that output is written to.

Unfortunately a description like "does absolutely nothing" doesn't
give us much to go by.

I am utilizing expect on several different servers. On one of them we
need to sftp two small files up to a service periodically through the
day. When I run the shell script in QSH it will run perfectly. Then I
run it again and it does absolutely nothing. It may be many minutes
before it will run again. Signing off and back on doesn't
consistently fix it either. When submitted to batch it's the same, it
may run and may not.

I am redirecting standard output to a log file (> 'output.log') and
when it runs correctly everything is in it. When it does not run the
file is correctly time stamped but is empty (0 bytes). Even when it's
not logging it may fail, in that case if it's interactive QSH simply
returns to the '$' prompt.

IBM i 7.1 with reasonably current PTFs and the latest version of
expect from ScottKlement.com.

Thoughts??
