FATA Serious error reading from tun device: read /dev/net/tun: not pollable

[Giancarlo1974]

I tested your mesh VPN on Oracle Cloud Free Tier using Oracle Linux 8

i got this error:
FATA Serious error reading from tun device: read /dev/net/tun: not pollable

i read that using unix.Open instead of os.OpenFile and setting the fd to NonBlocking seems to solve the problem

Can you fix ?
please

I'd be happy to take a PR to fix this, I think the right place to change would be here:

meshboi/tun.go

Line 33 in c5f221b

tunFile, err := os.OpenFile("/dev/net/tun", os.O_RDWR, 0)

. Let me know how it goes.

yes i think so too
But I don't know in which line to put this part of the fix:
setting the fd to NonBlocking
