 Jul 03 00:42:52.632 [notice] Tor v0.2.3.12-alpha-dev (git-
 e1ac458802b3cd18) running on Linux x86_64.
 Jul 03 00:42:52.632 [notice] Tor can't help you if you use it wrong! Learn
 how to be safe at https://www.torproject.org/download/download#warning
 Jul 03 00:42:52.632 [notice] This version is not a stable Tor release.
 Expect more bugs than usual.
 Jul 03 00:42:52.638 [notice] Initialized libevent version 2.0.16-stable
 using method epoll (with changelist). Good.
 Jul 03 00:42:52.638 [notice] Opening Socks listener on 127.0.0.1:0
 Jul 03 00:42:52.638 [notice] Socks listener listening on port 56396.
 Jul 03 00:42:52.000 [warn] You are running Tor as root. You don't need to,
 and you probably shouldn't.
 Jul 03 00:42:52.000 [notice] No AES engine found; using AES_* functions.
 Jul 03 00:42:52.000 [notice] This OpenSSL has a good implementation of
 counter mode; using it.
 Jul 03 00:42:52.000 [notice] OpenSSL OpenSSL 1.0.1 14 Mar 2012 looks like
 version 0.9.8m or later; I will try SSL_OP to enable renegotiation
 Jul 03 00:42:52.000 [notice] Reloaded microdescriptor cache.  Found 2869
 descriptors.
 Jul 03 00:42:52.000 [notice] I learned some more directory information,
 but not enough to build a circuit: We have no usable consensus.
