The X Command

master: `X from to user -options'

The `X' and the `-' are literal characters. This is a request by the master to, in essence, execute uucp on the slave. The slave should execute `uucp from to'.

from

This is the name of the file or files on the slave which the master wishes to transfer. Any wildcards are expanded on the slave. If the master is requesting that the files be transferred to itself, the request would normally contain wildcard characters, since otherwise an `R' command would suffice. The master can also use this command to request that the slave transfer files to a third system.

to

This is the name of the file or directory to which the files should be transferred. This will normally use a UUCP name. For example, if the master wishes to receive the files itself, it would use `master!path'.

user

The name of the user who requested the transfer.

options

A list of options to control the transfer. It is not clear which, if any, options are supported by most UUCP packages.

The slave then responds with an `X' command response. FSUUCP does not support `X' requests, and always responds with `XN'.

`XY'

The request was accepted, and the appropriate file transfer commands have been queued up for later processing.

`XN'

The request was denied. No particular reason is given.

In either case, the master will then send another command.
