URELAY(1) General Commands Manual URELAY(1) NAME urelay -- a UCSPI-based relay SYNOPSIS urelay [-hqVv] [-M msgsrc] [-m msgdst] [-S ignsrc] [-s igndst] DESCRIPTION The urelay tool is a simple relay client, based on Prof. Daniel J. Bernstein's UCSPI input/output framework. It expects to be executed by a UCSPI client application, and relays all data received on the stan- dard input to the UCSPI output channel, and all data received on the UCSPI input channel to the standard output. 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 speci- fied string, ignore it - do not send it to the outgoing connec- tion. -s igndst If the outgoing connection's data stream starts with the speci- fied string, ignore it - do not send it to the incoming connec- tion. -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 in- formation about its build environment. ENVIRONMENT Not taken in consideration in the present version. FILES None relevant in the present version. BUGS There should be a way to specify non-socket-specific behavior, e.g. skip fcntl(2) and shutdown(2) calls. HISTORY The urelay utility and this manual page was written by Peter Pentchev in 2002.
