URL decoding issue with link-local addresses

[xialvjun]

I must say Windows8 is much much better than 10 and 11.

[majestrate]

looks like an issue with locale

[xialvjun]

It seems have nothing to do with Win8.

I reinstalled Win10 and get same error..... Don't know why T-T

[xialvjun]

I think I have found the BUG

My CPU lscpu got Byte Order: Little Endian

@majestrate @neilalexander

[neilalexander]

The problem isn't your processor endianness. The problem appears to be because your network adapter is called 以太网 and Windows tries to put that into the link-local address, which the URL parser trips over.

I would guess that if you rename your 以太网 network interface to Ethernet (or something in Latin script) in Control Panel that the problem goes away?

[neilalexander]

Problem demonstrated here: https://go.dev/play/p/TRVFjToeE4Y

In short, this looks like a problem in the upstream Go standard library and probably affects various non-Latin scripts.

[xialvjun]

Thanks，after I renamed 以太网 to Ethernet, yggdrasilctl getpeers doesn't get error. But I still can not ping to it.

Both ErrorPC and OkPC are connecting to the same peers, OkPC should can ping to ErrorPC.

Notes the OkPC's conf file is generated by 0.4.7, I didn't change it when update to 0.5.4. ErrorPC's conf file is generated by 0.5.4 with just added same peers.

Try yggdrasilctl.exe getSessions during/after pinging. If you see a session for the address you're trying to reach, but aren't getting ping responses, then it's probably a firewall on the host dropping the pings.

[Vort]

But I still can not ping to it.

Can you ping other nodes in the Yggdrasil network?
Like 200:b858:3f39:af76:83ae:bb1:ebb2:604e from your output.

[xialvjun]

@neilalexander Thank you very much. I did find it in yggdrasilctl getSessions. And after I turning off the ErrorPC's firewall, everything works.Thank you all.
