The epp clients are programs that implement the registrar portion Extensible Provisioning Protocol. The tools must be able to communicate with the EPP Frontend, using the EPP Transport over TCP mappings as defined in draft-ietf-provreg-epp-tcp-05.txt.
The ISC OpenReg software distribution includes a sample client program
bin/epp-from-file that implements EPP so that comprehensive
server testing can be performed. Currently, the best documentation for
the bin/epp-from-file is located in the
test/epp/README file.
