Hi,

I'll be managing the bridge at U of Minnesota

Bridgeline:

Bridge obfs4 146.57.248.225:9000 10A6CD36A537FCE513A322361547444B393989F0 cert=K1gDtDAIcUfeLqbstggjIw2rtgIKqdIhUlHp82XRqNSq/mtAjp1BIC9vHKJ2FAEpGssTPw iat-mode=0

Here's the relevant stuff from torrc

ORPort 443 

BridgeRelay 1

ExtORPort auto

ServerTransportPlugin obfs4 exec /usr/local/bin/obfs4proxy

ServerTransportListenAddr obfs4 0.0.0.0:9000

Thanks for setting up this bridge! I'm able to connect to your bridge's OR port but its obfs4 port seems unresponsive. Is your firewall allowing port 9000?

Other than that, your config looks good.

We keep having problem with firewall every once in a while. Is it fine if I change obfs4 port to 22 ? That would not be harmful to the clients in any way, right?

Yes, feel free to use port 22 instead. The most important thing is that the port will be consistently available.

Thanks jvsg, this bridge line works for me.

BridgeDistribution None


This should be none instead of None because tor's config options are case sensitive.

Thanks! For what it's worth, this was a usability issue and Roger filed #32753 to get it fixed. Everything's looking good now, so let's add your bridge to Tor Browser.

Tor Browser Team:

For the record, I also updated our list of default bridges and added our new bridge to our sysmon config.

Thanks. Looks good. I merged your commits to tor-android-service's master (commit 4a81e5806f36e7d0bf9492437d824599ecf4ff43) and tor-browser-build's master (commit 00f4ea3a18f1cbce16f256ca2b7c1c90ad3b1daf) and bumped the tor-android-service commit there to pick up the changes for mobile, too (commit 8f76d71e2a0923d3ca317f82ab5eeec124706e22).

I backported the latter two to maint-9.0 (commit 095dfed8762cd1756b3fc50ed4aa6e8f2d0dc849 and d6bd267e1747a14d2a326a36099bf8e79bbc6a91) to have the bridge available in the next stable release as well.
