The following options are available: -h Display a short help message and exit. -M msgsrc Send the specified string to the incoming connection as soon as the forwarding tunnel has been established. -m msgdst Send the specified string to the outgoing connection as soon as the forwarding tunnel has been established. -S ignsrc If the incoming connection's data stream starts with the specified string, ignore it - do not send it to the outgoing connection. -s igndst If the outgoing connection's data stream starts with the specified string, ignore it - do not send it to the incoming connection. -q Quiet operation. urelay is even more quiet when more than one -q flag is specified. -V Display version information and exit. When combined with one or more -v switches, -v Verbose operation. urelay is even more verbose when more than one -v flag is specified. urelay also attempts to display information about its build environment.
