SYNOPSIS

rcpd [ -a -n ]

DESCRIPTION

The Rcpd exists to copy files between machines. It listens for service requests at the port indicated by the shell services specification; see services(5).

Rcpd offers up files from the /tftpboot directory (or another build-time configured directory), optionally prepending the source IP address (followed by a /) to the filename specified (again, optionally configured at build-time. The default is not to do this).

Rcpd tries to offer the same security model as tftpd by only writing to files that exist and are writable by user nobody and only reading from files that are readably by user nobody.

If the -a option is specified, hostnames are reverse-resolved and connections are aborted if addresses and names are not consistent.

Transport-level keepalive messages are enabled unless the -n option is present. This is probably entirely irrelevent for rcpd.

HISTORY

The rcp utility appeared in 4.2BSD. The rcpd utility is based on the 4.4BSD (Lite) versions of rcp and rshd. rcpd was written by John Hawkinson; the idea for this came from a discussion with Bill Fenner.

BUGS

Prevents you from running an rshd.

Doesn’t have very elaborate negotiation, but it’s a damn sight better than tftp.
