Hi Nikos, OK, yeah I'm not about failure at start-up time. If an SMSC is off-line (SMPP timeout/retry during bind) kannel will start (simply config a bogus IP address for SMPP to test this out). An example is lets say we have 2 connections for load balancing. Now consider 1 smsc being taken offline (no tcp connection) as it is upgraded, we can still send through the other (this is also useful for DR - disaster recover, etc).
So from my example above only 1 connection would be active the other in bind retry loop (wait X seconds, etc) - no tcp connection is established to smsc. If we re-started kannel it wouldn't be a good idea to wait for both links to become active before pushing messages out - this would mean waiting for the upgraded smsc to come back online, no? Again sorry if I'm talking at cross purposes here. Cheers, Alan Nikos Balkanas wrote: > Hi Alan, > > If even 1 SMSc in configuration file fails to start, bearerbox will > panic.
