(I'm still kinda new to most of this, so apologies)
My server has dual ethernets, ones is plugged into router and the other is directly connected to windows machine.
After upgrading to 6.12.0 or 6.12.1 I cannot access the server or GUI through the dedicated ethernet.  (the standard router address works)

reverting back to 6.11.5 solves the issue

 

The syslog on 6.11.5 has this line switching the interface on: 

"avahi-daemon[3277]: Joining mDNS multicast group on interface eth1.IPv4 with address 169.254.***.***"

on 6.12 it no longer does and only has it for the router address

 

I'm pretty sure its something simple I have to allow eth1 somewhere in a config 

According your description, you set eth1 allocate IP by DHCP, but as no DHCP in that network, so finally it will assign 169.254.*.*

 

I haven't test does 6.12.x will do same thing, but in general won't setting in that way.

 

Pls simple assign static IP and Subnet to eth1 ( gateway in blank ), for example if router network in 192.168.1.1 with 255.255.255.0 then set eth1 in 192.168.2.X with 255.255.255.0 and windows machine in 192.168.2.Y 255.255.255.0 ( also gateway in blank ) should solve your problem.

The pc and server are directly connected hence the local link IP address range.

 

They are set as static on both sides, the settings all come over fine on the update.

 

on 6.12.0/1 it just isn’t listening on eth1.

 

I wonder if it’s something with avahi-daemon. (Like eth1 is set to disabled) But I can’t seem to find where it’s config is

Does Unraid and Windows can ping each other in eth1 network ? Pls post Unraid diagnostic zip file as usual.

Now for the newbie element from me, how exactly to I ping each of them?

 

I’ll post the diagnostic file tomorrow morning.

OK.

 

For Unraid, open web terminal then ping Windows IP

 

Here we go, ping seems to work.

169.254.117.248 is eth1 IP, you need ping Windows IP.

 

BTW, just simple test, as mention before, pls assign a static IP & subnet at Unraud eth1 and Windows

 

 

At least it should work with 6.12.1

So if I set eth1 as static I get the warning "Interface Ethernet Port 1 is down. Check cable!"
 

Ping still works though.

When you change network settings, interface will up and down, and you need waiting Windows side link up too.

 

If you " lsof | grep 169.254 " haven't found service listening on that, you must set static IP.

yeah, still not working.  I've added eth1 to include listening (new setting on 6.12)

This will be solved in the upcoming version 6.12.2
