sorry i forgot to take that part put. that part is not related to the error message.that file check bzy file and works fine.
i got that message "stty: standard input: Invalid argument" when i run the program through cron and it shows when trying to ping to the server.

thanks for your help
When run as a cron job, your script does not have a controlling terminal defined. You need to track down what part of your environment is responsible for attempting to call the 'stty' utility. Ozo spotted the check_connect_direct script as a possible place where this is happening. Another possibility is that you have a shell that automatically tries to read .profile and it is attempting to execute commands from there (though that doesn't look likely in your case). Your 'sendmon' command might be another possibility.

What user does the cronjob run as?

Check in the .profile for that user and I'm sure you'll see some stty settings.

BTW:  Did you really mean to post in the Perl group?
> stty: standard input: Invalid argument
at least one of your called scripts uses stty which is not possible in cron
(in short what others already said:)
