AFAIK, GNU version of netcat doesn't support unix socket, maybe you need the openbsd version. $ yum info nc Installed Packages Name : nc Arch : x86_64 Version : 1.101 Release : 3.fc16 Size : 28 k Repo : installed >From repo : anaconda-0 Summary : Reads and writes data across network connections using TCP or UDP URL : http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/nc/ License : BSD ISC Description : The nc package contains Netcat (the program is actually nc), a simple : utility for reading and writing data across network connections, using : the TCP or UDP protocols. Netcat is intended to be a reliable back-end : tool which can be used directly or easily driven by other programs and : scripts. Netcat is also a feature-rich network debugging and : exploration tool, since it can create many different connections and : has many built-in capabilities. : : You may want to install the netcat package if you are administering a : network and you'd like to use its debugging and network exploration : capabilities.
