[tor-relays] RPM upgrade issue.



Hello,

Happy New Year, everone! I've been chasing this down here for the last hour or so and I thought I might as well share it since others might also experience it.

I am running https://atlas.torproject.org/#search/plutonium

After running yum update this lead to a different fingerprint being generated for the same host.

Nov 29 01:09:27 Installed: tor-0.2.5.10-tor.2.rh6_5.i686

Dec 29 19:21:07 Installed: torsocks-2.0.0-2.el6.i686

Dec 29 19:21:10 Updated: tor-0.2.5.10-1.el6.i686

Then, traffic collapsed by going down from <> 8MB/sec to pretty much nothing.

I checked the logs and found permission errors. The group for Tor was changed from _tor to toranon, so the permissions were wrong after the rpm was installed.

Also, /etc/tor/torrc had this line commented :

## The directory for keeping all the keys/etc. By default, we store
## things in $HOME/.tor on Unix, and in Application Data\tor on Windows.
DataDirectory /var/lib/tor

So it was defaulting to ~tor directory,

tor/tor.log-20141230:Dec 30 03:13:01.000 [warn] Default DataDirectory is "~/.tor".  This expands to "/.tor", which is probably not what you want.  Using "/var/tor" instead

[root@plutonium log]# rpm -qa | grep tor
torsocks-2.0.0-2.el6.i686
tor-0.2.5.10-1.el6.i686

I fixed the permissions, but I am seeing this message now that I have not seen before.

Jan  1 21:36:02 p15186978 Tor[28986]: Invalid result from curve25519 handshake: 4

Should I be concerned about this message?
