AFPproxy is an MIT licensed proxy for an AppleShare file server. You can use it to help debug client/server connections on Mac OS X, but I wrote it to explore the Twisted networking framework.
When running, the proxy prints details of the client/server communication to stderr.
Requires Python 2.5 or later and Twisted. AFPproxy does not run on Python 3. Mac OS X 10.5 and later include Python and Twisted by default.
You can download and install the source directly:
tar -xf afpproxy-0.1.tar.gz cd afpproxy-0.1 python setup.py install
Or install it from PyPI:
pip install afpproxy
If you don't have Twisted installed, install it. For Python 2.5 install it with:
pip install 'Twisted<12.2' 'zope.interface<4'
Once installed, start the proxy with the afpproxy command.
By default this proxies your real AFP server on localhost port 548, and accepts connections on port 5548. You then connect to the running afpproxy and will see a description of the commands sent between client and server.
To proxy to a different server give its name or IP address:
afpproxy --host example.com
Or to proxy to a server running on a non-standard port:
afpproxy --host example.com --port 1234
To start a proxy listening for connections on port 1548:
afpproxy --listen 1548
By default afpproxy will log (relatively) meaningful information about the requests and responses. If you want to see the bytes of each and every command use the --debug flag:
afpproxy --debug
