faulty params on trace tasks: wrong local_address assignment #70

Closed igarny closed 7 years ago

igarny commented 7 years ago

Hi Andy In the GEANT production mesh I ended up with failing trace tests (source and destination swapped):

''' { "diags": "traceroute -q 1 -6 -s psmp-gn-owd-01-bud-hu-v6.geant.net -m 64 -N 64 -n psmp-gn-owd-01.gen.ch.geant.net 40", "result": null, "succeeded": false, "error": "\nbind: Cannot assign requested address\n" } ''' https://psmp-gn-bw-01-gen-ch.geant.net/pscheduler/tasks/f890d9f1-eb27-4079-abea-779df955da10/runs/33864053-db27-4c60-ab3d-91b120d3e3d9

meshconfig is:

=> wrong task....this is for the latency interface, which also fails

here is the pscheduler task: 2017-06-01T11:15:30Z - 2017-06-01T11:15:30Z (Finished) trace --dest psmp-gn-owd-01.gen.ch.geant.net --ip-version 6 --length 40 --source psmp-gn-owd-01-bud-hu-v6.geant.net --hops 64 (Run with tool 'traceroute') https://psmp-gn-bw-01-gen-ch.geant.net/pscheduler/tasks/f890d9f1-eb27-4079-abea-779df955da10/runs/cc4f9032-04ec-42a4-9cde-f9fad2d800d1

I am looking at the possibility of issues in my config. It might have been some "old" tasks with bad config scheduled in a transition state or something?... Anyway... I have found reports of successful measurements on the reported case.
