DESCRIPTION

The macat command is a command‐line interface to send and receive data via the mangos implementation of the SP nanomsg protocols. It is designed to be suitable for use as a drop‐in replacement for nanocat(1).

Additionally it has a some extra features, to support mangos' additional capabilities. In particular, it supports SSL/TLS, and has a few flags related to that.

SSL/TLS DETAILS

The security model for macat is that authentication should be mutual by default. Therefore, the user should normally supply both a certificate/key (either in a single file, or in separate files with --key), and a CA certificate file (perhaps consisting of many certificates) which should have been used to sign the peer's certificate. This is true for BOTH client and server. (This is a but unlike traditional HTTPS, where it mutual authentication is the exception rather than the rule.)

A client can choose to skip verification of the server by supplying the --insecure (-k) flag instead of the --cacert argument. This is not recommended. It can also choose not to authenticate itself to the server by simply not supplying a --cert and --key.

The server (the party doing the bind) MUST always supply its own certificate. It will normally attempt to authenticate clients, but this can be disabled by supplying --insecure or -k instead of the --cacert argument.
