actually the cause.
It's really easy to reproduce. Just use a SOCKS tunnel as a
pseudoâpluggable transport.
{{{
ssh -v -N -D 9001 people.torproject.org
}}}
Without a fingerprint, you get two connections through the tunnel:
{{{
tor ClientTransportPlugin "dummy socks5 127.0.0.1:9001" UseBridges 1
Bridge "dummy 128.31.0.34:9101"
}}}
{{{
debug1: Connection to port 9001 forwarding to socks port 0 requested.
debug1: channel 2: new [dynamic-tcpip]
debug1: Connection to port 9001 forwarding to socks port 0 requested.
debug1: channel 3: new [dynamic-tcpip]
}}}
If you include the fingerprint, you only get one:
{{{
tor ClientTransportPlugin "dummy socks5 127.0.0.1:9001" UseBridges 1
Bridge "dummy 128.31.0.34:9101 9695DFC35FFEB861329B9F1AB04C46397020CE31"
}}}
{{{
debug1: Connection to port 9001 forwarding to socks port 0 requested.
debug1: channel 2: new [dynamic-tcpip]
}}}
