Re: [Kannel-Users] Re: SMPP re-connect termination.

Do you think we can add a flag in the config to set a retry time for a
failed login?  It seems several SMSC's have this problem where when they
restart their systems, the authentication is not up and running before the
SMSC accept portion.  This has happened to me on several occasions, and
would love to be able to override the system default of giving up to change
it to "try in 60 seconds, 5 more times".  This avoids the potential for
abuse, but gives the remote system enough time to "start back up."

Thoughts?  Two flags?  bad_password_retry_time = 60
                        bad_password_retry_times = 5

By default it dies.
