Seems like there is an error in auto selection of vnet_default_interface

sonicaj commented 5 years ago

Can you please share the output of netstat -nr and also please use triple back ticks before/after of the output to format it properly. It's very hard to read otherwise.

like this is in triple back ticks

Also it would be nice if you could share the output of ifconfig again in backticks ( to make it more readable ). Thank you @kitten77

sonicaj commented 5 years ago

Plus it seems you have suppressed output of iocage get all, please don't do that as diagnosis becomes difficult otherwise

kitten77 commented 5 years ago

I normally do not use ipv4 so what i discovered now is that there wasn't a default ipv4 route out, so i am guessing the auto selection is based up on default route. and since there was no 0.0.0.0 route it could not determin the default interface... Yeah i surpressed it since it was not a full output

sonicaj commented 5 years ago

I would recommend trying master as lots of ipv6 changes have been committed since your version

kitten77 commented 5 years ago

yeah I am on my way to master, was just testing the 1.1 for fun. setting up a new working enviroment, and that is always a good time to test the pkg install

kitten77 commented 5 years ago

but that error could have been clearer on what was missing and needed to be set manually took me sometime to actually figure out why it was crashing
