The -manager argument is required, and it specifies the network address of the proxy manager. The format of the address is a standard ICE network id (for example, "tcp/blah.x.org:6500").
The -name argument is required, and it specifies the name of the desired proxy service (for example, "LBX"). The name is case insensitive.
The -server argument is also required, and it specifies the address of the target server. The format of the address is specific to the proxy service specified with the -name argument. For example, for a proxy service of "LBX", the address would be an X display address (e.g, "blah.x.org:0").
The -auth argument is optional. If specified, xfindproxy will read 2 lines from standard input. The first line is an authorization/authentication name. The second line is the authorization/authentication data in hex format (the same format used by xauth). xfindproxy will pass this auth data to the proxy, and in most cases, will be used by the proxy to authorize/authenticate itself to the target server.
The -host argument is optional. If xfindproxy starts a new proxy service, it will pass the host specified. The proxy may choose to restrict all connections to this host. In the event that xfindproxy locates an already existing proxy, the host will be passed, but the semantics of how the proxy uses this host are undefined.
The -options argument is optional. If xfindproxy starts a new proxy service, it will pass any options specified. The semantics of the options are specific to each proxy server and are not defined here. In the event that xfindproxy locates an already existing proxy, the options will be passed, but the semantics of how the proxy uses these options are undefined.
If xfindproxy is successful in obtaining a proxy address, it will print it to stdout. The format of the proxy address is specific to the proxy service being used. For example, for a proxy service of "LBX", the proxy address would be the X display address of the proxy (e.g, "blah.x.org:63").
If xfindproxy is unsuccessful in obtaining a proxy address, it will print an error to stderr.
