out-of-order errors

[robert.b...@gmail.com]

Hi guys,

started using NDR, it is a super nice tool, great work.

Checking error-plugins, and we are using these by default:

        allowed_errors = {'client': {u'tcps_conndrops': u'embryonic connections dropped',
                                     u'tcps_rcvduppack': u'duplicate-only packets received',
                                     u'tcps_rcvoobyte': u'out-of-order bytes received',
                                     u'tcps_reasfree': u'free tcp reasembly ctx',
                                     u'tcps_reasalloc': u'allocate tcp reasembly ctx',
                                     u'tcps_rcvdupbyte': u'duplicate-only bytes received',
                                     u'tcps_rcvoopack': u'out-of-order packets received'},

                          'server': {u'err_no_template': u"server can't match L7 template",
                                     u'err_no_syn': u'server first flow packet with no SYN',
                                     u'tcps_sndrexmitpack': u'data packets retransmitted',
                                     u'tcps_sndrexmitbyte': u'data bytes retransmitted',
                                     u'tcps_rcvdupack': u'rcvd duplicate acks'}

What does "out-of-order packets received", does it mean out-of-order packets in the same traffic-flow, or is it out of order in general between flows?

Is there a way to continue the traffic even if we get accepted errors?

Thanks,

Same flow of course.

Thanks Hanoch,

and "Is there a way to continue the traffic even if we get accepted errors?" in NDR?
