localhost mapping issues

[clinton.hall]

I use Bitvise SSH client to connect to my AS-604T. I then have ClientToServer mapping enabled.
When I map to the destination localhost:8000 I can access the admin page but mapping localhost:5050 will not access CouchPotato's web UI. However mapping 127.0.0.1:5050 does work.

Likewise for CouchPotato and SickBeard to send NZBs to NZBGet and for NZBGet postprocessing (nzbToMedia) back to CouchPotato and SickBeard I must use 127.0.0.1 and not localhost.

After investigating, I noticed that /etc/hosts looks like this:

Code: Select all

::1	localhost
127.0.0.1	localhost
10.1.1.9	AS-604T-EA70
169.254.1.3	AS-604T-EA70

when I test Bitvise using ::1 I can access admin page on port 8000 but cannot access CouchPotato on 5050, but both are accessible when using 127.0.0.1

So I believe the admin page accepts connections on ipv6 whereas CouchPotato, SickBeard , NZBGet (and possibly many other Apps) do not.
Obviously the work-around is to use 127.0.0.1; but would it be possible to change the default order of the ipv6 v ipv4 localhost mapping in /etc/host or is there a way to make the system use both (and not just the first entry)?

Hi Clinton,

Thanks a lot for the information : )

I have passed this to our engineers. We will apply this change in future updates!
