Re: [tor-relays] Exit probability

[Sebastian Urbach <sebastian@xxxxxxxxxx>]

Hi,

Both servers do not have the Exit flag but every other flag necessary to 
become an Exit and Exit policies are also present. That could indicate some 
port trouble:

"Exit" -- A router is called an 'Exit' iff it allows exits to at least one 
/8 address space on each of ports 80 and 443. (Up until Tor version 0.3.2, 
the flag was assigned if relays exit to at least two of the ports 80, 443, 
and 6667.)

The Exit probability is 0 without the Exit flag. 200 Exit connections 
without the Exit flag ? Seems ylto be weird...
