Oct 15 00:47:33.252 [notice] This version is not a stable Tor release.
Expect more bugs than usual.
Oct 15 00:47:33.252 [notice] Read configuration file "/root/test".
Oct 15 00:47:33.253 [notice] Your ContactInfo config option is not set.
Please consider setting it, so we can contact you if your server is
misconfigured or something else goes wrong.
Oct 15 00:47:33.253 [notice] Based on detected system memory,
MaxMemInQueues is set to 743 MB. You can override this by setting
MaxMemInQueues by hand.
Oct 15 00:47:33.253 [notice] By default, Tor does not run as an exit
relay. If you want to be an exit relay, set ExitRelay to 1. To suppress
this message in the future, set ExitRelay to 0.

Oct 15 00:47:33.000 [notice] You are running a new relay. Thanks for
helping the Tor network! If you wish to know what will happen in the
upcoming weeks regarding its usage, have a look at

Oct 15 00:47:33.000 [notice] It looks like I need to generate and sign a
new medium-term signing key, because I don't have one. To do that, I need
to load (or create) the permanent master identity key. If the master
identity key was not moved or encrypted with a passphrase, this will be
done automatically and no further action is required. Otherwise, provide
the necessary data using 'tor --keygen' to do it manually.
