Dear Keifer,

I'm sure the gurus can say exactly what happens in an upgrade, but I can say that it is the keys in /var/lib/tor/keys that uniquely define your tor instance. As you did not transfer the keys from the windows box, they were created anew when you first started up tor, and your box is considered a new relay.

I don't think this is a problem, especially as new bridges 1. are needed for May35th(Tinamann Square) right now, when China usually locks down its internet "just in case" and 2. bridges gradually get discovered and blocked, so starting anew is a plus, not a minus.

HTH,

Hi all,

So I am switching my OBFS4 bridge that was here

https://metrics.torproject.org/rs.html#details/386E99371B8CD938248940B754F16AAC54B5712B 

From running on Windows to running on Debian, as the older computer I was running it on, Windows updates started causing it to not boot correctly haha. With some work I was able to get Debian running on the machine.

I am wondering, does unattended upgrades as configured here:  https://trac.torproject.org/projects/tor/wiki/TorRelayGuide/DebianUbuntuUpdates 

Keep OBFS4 up to date as well?

Is it safe to use tor browser through teamviewer from the computer I am running the bridge on?

Unfortunately the relay key for the former bridge was lost as  the hard drive failed due to a Windows update causing it to crash, do the bridge relay keys have any other relevance than flags?

Thanks very much.
