v1.9.0 error

[Bug5532]

Hi, I'm getting this error when I try to run the example scene.
IP address cannot be determined!
UnityEngine.Debug:LogError(Object, Object)
TNManager:Awake() (at Assets/TNet/Client/TNManager.cs:790)

and then:
[TNet] Udp.Start: The requested address is not valid in this context
UnityEngine.Debug:LogError(Object)
TNet.UdpProtocol:Start(Int32) (at Assets/TNet/Common/TNUdpProtocol.cs:117)
TNUdpLobbyClient:OnEnable() (at Assets/TNet/Client/TNUdpLobbyClient.cs:67)

What should I do to fix this? It was working before I updated.

What's your target platform? Any way I can reproduce this on my end? You can change the way IP was determined back to how it was by going to line 105 of TNTools.cs (it's a try/catch block). Get rid of the entire "try" block and comment out the "catch exception" line, leaving only the DNS part that follows.

I just set up a completely blank project to test it out. So brand new project, imported the tnet unity package and opened the scene example menu. Hit play and got the error message. Target was PC, Mac & Linus Standalone as it was a new project.
This is on a macbook pro in the editor, I dont know if that has anything to do with it.
I'll try reverting it now.

That's interesting... the only way that point can be reached if the list of local IPs could not be determined. The list of IPs is retrieved in TNTools.cs, Tools.localAddresses. It's done by querying the hardware, getting the list of network interfaces, then iterating through them to find valid IPs. I need to know which part of that is failing on your machine, because I am running Windows 8.1 here and everything works as expected. It even has a fallback there where if it's not possible to determine the IPs using this method it reverts to the old way of doing it -- via DNS.

It seems I have the same issue.
I've logged some information, and the issue seems to come from TNTools.cs in the get of networkInterfaces.

I'm on an iMac, and NetworkInterface[] list = NetworkInterface.GetAllNetworkInterfaces(); give me a list of 9 items.
After that, for each item you test if they support IPv4 and if OperationalStatus == OperationalStatus.Up, here is the result for the 9 items :
(name - support IPv4 - operationalStatus)
lo0 - True - Unknown
gif0 - False - Unknown
stf0 - False - Unknown
en0 - False - Unknown
fw0 - False - Unknown
en1 - True - Unknown
en4 - False - Unknown
en5 - False - Unknown
p2p0 - False - Unknown

I'm on Skype if you need any more information.

nah0y and I spent 2 hours on Skype to get to the bottom of the issues. Seems everything should work now in 1.9.0b.

[Bug5532]

Thanks a lot to both of you for finding a fix. Sorry I couldn't have been more help. I will give 1.9.0b a go now

Reading Unity 4.5 release notes, there is :
- Mac OS X Standalone: Fix GetAllNetworkInterfaces.


So maybe this will fix the issues we had...
