#2351: polipo-1.0.4.1 logs port 2050 instead of 8118

 Reporter:  jchau        |        Type:  defect
   Status:  new          |    Priority:  normal
Milestone:               |   Component:  Polipo
  Version:  Polipo: 1.0  |    Keywords:

-------------------------+--------------------------------------------------
 I am using net-proxy/polipo-1.0.4.1 with net-misc/tor-0.2.1.28 on Gentoo
 Linux.

 I configured polipo with the configuration file from
 <https://gitweb.torproject.org/torbrowser.git/blob_plain/HEAD:/build-
 scripts/config/polipo.conf> with the following modifications, which enable
 logging and enables cachedIsShared:

 < cacheIsShared = false

 > cacheIsShared = yes



 When I start polipo, it consistently logs the following (regardless of
 whether I start polipo as myself (using the command "polipo" without
 arguments) or use the init.d script to start it as user polipo):
 Established listening socket on port 2050.


 This is problematic because I have not configured polipo to use port 2050
 for anything.  As shown below, I don't ever mention 2050.  Below is the
 output of "polipo -v | grep -i port":
 allowedPorts intlist 1-65535 Ports to which connections are allowed.
 parentProxy atom (none) Parent proxy (host:port).
 proxyPort integer 8118 The TCP port on which the proxy listens.
 socksParentProxy atom localhost:9050 SOCKS parent proxy (host:port)
 tunnelAllowedPorts intlist 1-65535 Ports to which tunnelled connections
 are allowed.


 Furthermore, I can't find any open port 2050 open on my computer; "netstat
 -n -l" shows:
 Active Internet connections (only servers)
 Proto Recv-Q Send-Q Local Address           Foreign Address         State

 tcp        0      0 127.0.0.1:8118          0.0.0.0:*               LISTEN

 tcp        0      0 127.0.0.1:9050          0.0.0.0:*               LISTEN
 udp        0      0 0.0.0.0:631             0.0.0.0:*

 (Listing of UNIX domain sockets follow, but no 2050 shows there either.)


 Tor with Torbutton appears to work properly despite this polipo claiming
 to use port 2050.  Still, this confusing log message makes me think that
 something is wrong.

 I tried looking at the polipo source, but I still can't figure out why it
 would output 2050.  Does anyone else notice this?

 Attached is /etc/polipo/config.
