proxy ftp-command

Execute an ftp command on a secondary control connection. This command allows simultaneous connection to two remote ftp servers for transferring files between the two servers. The first proxy command should be an open, to establish the sec- ondary control connection. Enter the command "proxy ?" to see other ftp commands executable on the secondary connec- tion. The following commands behave differently when pref- aced by proxy: open will not define new macros during the au- to-login process, close will not erase existing macro defini- tions, get and mget transfer files from the host on the pri- mary control connection to the host on the secondary control connection, and put, mput, and append transfer files from the host on the secondary control connection to the host on the primary control connection. Third party file transfers de- pend upon support of the ftp protocol PASV command by the server on the secondary control connection.
