#weavenetwork

hey guys, im just trying to setup a new weave network. Unfortunately weave complains for all connections that it wont connect to itself: "Info": "cannot connect to ourself, retry: never". Any hints?

There is some traffic on TCP Port 6783 between the hosts, so something is happening

Are the "Names" from weave status supposed to be the same on all machines?

OK, when i statically set Names, e.g. ::1 - it works. But im 100% sure it worked before without it.

hi, opthomasprime

"Names" shouldn't be the same on all machines, because it is a unique ID per machine

how do you start the weave network?

From the info msg it seems that you are passing hostname/ip of a machine as a peer parameter when launching weave

which won't work

yes, i do pass the hostnames of the peers at the launch command. like: Host A: weave launch host_a / Host B: weave launch host_b.

Do yoou know how the unique ID is/should be created?

opthomasprime: you should start weave on host A by "weave launch host_b" and on host B "weave launch host_a"

oh darn - that was a typo

i do start weave like u just wrote

but they still get the same Names and wont connect to each other

when i define a name at the launch command it works

it depends. please see https://www.weave.works/docs/net/latest/operati... for details.

are host_a and host_b virtual machines?

my new hosts are dedicated boxes from online.net

but the link you posted gave me a hint

From the BIOS product UUID, which is generally stable across restarts and unique across different physical hardware and certain cloned VMs

-> From "When the router is launched on a host, it derives its peer name in order of preference"

It seems like all hosts have the same product UUID

which results in the identical weave Name...

could you "cat /sys/class/dmi/id/product_uuid"?

i did it with dmidecoode

but yes, they are all teh same

12345678-1234-5678-90AB-CDDEEFAABBCC

seems generic

so i guess i have to specify the names on all hosts manually at this hoster

or is there a way to "force" weave using another scheme

?

unfortunatelly noup, so you need to specify the names manually

ok

i can live with that

but atleast i know whats wrong...

i started to feel dumb

do you think i should open an issue on github regarding this problem?

yep, go for it, thanks!

anyways, thank you martynas!
