I try using mirror 2.9 (old, very old perl script) to mirror ftp site
in passive mode and see don't working restart transfer: server ignored
'REST pos' command.
This because in ftpcmd.y cleared restart_point:
: /* empty */
| cmd_list cmd
fromname = NULL;
restart_point = 0;
| cmd_list rcmd
(cmd is any command execept RNFR and REST) and mirror in passive mode
used next command sequence:
RFC 3659 allow this, but not recomeded:
"The server-PI may react to a badly positioned REST command by ....
save the restart value and apply it to the next data transfer command
Why this case (save the restart value) is bad choice?
