Hi,

does os.networkInterfaces() returns mac addresses (node internal function)? Can you post the output?

[sebhildebrandt]

Seems to be an node issue, with node 7.x I got correct mac addresses, node 8.4 does not return correct mac addresses. See nodejs/node#13581

[sebhildebrandt]

There is already a pull request in the node repo, that should fix this issue.

@sebhildebrandt
os does return correct.

Yes, os returns it correct but the node built-in function os.networkInterfaces() has an issue (which has already a pull request). As soon as this gets into the node core, System Information will again return correct values. Hope that is fine for you.

You could circumvent this issue temporarily till the node bug gets resolved by downgrading to Node v7 as, like @sebhildebrandt mentioned, the mac address detection works like a charm there.

[sebhildebrandt]

Anyway, I hope the node team will merge the pull request on their side soon ;-)

I think you may close this issue now.

[frank-dspeed]

I only wanted to report that i don't have any problems i droped this package already in favor of my own class that calls os and does exec

@sebhildebrandt Maybe you can use https://github.com/node-modules/address as your dependency to get MAC address. Because it has a fallback solution to get the right MAC address during the wrong versions of Node.js.

[sebhildebrandt]

@XadillaX: I guess you are right, waiting for the pull request on node.js side will anyway not fix the problem that with some node.js you will have wrong MAC addresses. As I want to keep this library dependency free, I will implement a fallback code to get correct MAC versions. I will try to do it next week. And btw. thank you for your comments/suggestions!

[sebhildebrandt]

Just published a fix for that ...
