:SELinux is preventing /usr/bin/polipo from 'name_connect' accesses on the tcp_socket .
:*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************
:If you want to allow system to run with NIS
:Then you must tell SELinux about this by enabling the 'allow_ypbind'boolean.
:setsebool -P allow_ypbind 1
:*****  Plugin catchall (11.6 confidence) suggests  ***************************
:If you believe that polipo should be allowed name_connect access on the  tcp_socket by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep polipo /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2012-05-21 08:09:03 UTC
Did it happen by default?

Comment 2 Daniel Walsh 2012-05-21 14:20:39 UTC
Or is there a configuration that you changed to get polipo to connect to a web server?

Comment 3 smitna 2012-06-18 14:26:12 UTC
Sorry for the late reply and thank you for the follow up.

I do not recall making any configuration changes to the polipo package.

$ rpm --verify polipo
.M...U...    /var/run/polipo

Comment 4 Dominick Grift 2012-06-18 14:32:43 UTC
# Uncomment this if you want to use a parent proxy:

# parentProxy = "squid.example.org:3128"

# Uncomment this if you want to use a parent SOCKS proxy:

# socksParentProxy = "localhost:9050"
# socksProxyType = socks5

I am not aware of the need for polipo to connect to port 80, Although we probably should give it access to connect to 3128 for squid access? (see above config snippet)

Comment 5 Dominick Grift 2012-06-18 14:34:59 UTC
Actually since its a web caching proxy it makes sense that it connect to tcp:80

I only tested it with Tor.
