Thanks Wiggins and Rob, '$ftp->site("CHMOD 755 $file")' worked the first
time I popped it in - perfectly.
Oddly, '$ftp->command("SITE CHMOD 755 $file")'and '$ftp->quot("SITE
CHMOD 755 $file")' wouldn't hang the connection, and they would did
successfully execute the chmod command via the ftp connection (I checked
with an ftp client and every file in the base directory did show a
successful chmod change), it just seemed to somehow corrupt the capacity
to call cwd in any way, and always returned '' for the current
directory, even though the ->quot was continuing to work for chmods.
I'll file this behavior in the 'mystery box' (as it is usually user
error anyway) and keep using the site function, thanks again.
