Re: [tor-relays] Call for setting up new obfs4 bridges

Hi,

Thanks for the reply. Yes, I ran that command way back at the start. I'm assuming I don't have to run it every time the machine reboots or updates? I ran it again this morning and it made no difference.

Ah logs, you say that like I know where those are :P
When I run sudo tail /var/log/tor/log - I get nothing.
I found the Logs app and run that to get all the system logs - way too much stuff and I couldn't move it to here, so I found this command (Google) cat /var/log/syslog | grep tor -i and got the following (I think I've included 2 set of attempts to boot up):

To run obfs4 on port 443, you will have to run the following command, to

If you did that already, it would be helpful to see your logs.
