I'm trying to lock down a FTP server. One thing I'd like to do is assign
different permissions for directories and files. Is there a way I can
recursively assign permission based on whether it's a directory or a file?

man chmod
chmod -R mode file
for simplicity I use mc (midnight commander) whitch does it as well

Correct me if I'm wrong but when I do a "chmod -R 755 *", it'll set every
file and directory to 755. What I want to do is set every file to 444 but
every directory to 666. That way all the files can be read but not
modified. Directories, however, need to be executed in order to be browsed;
that's why I want to set it as 666.

Anyone else have any idea?

Have a look at the permission symbol 'X' in chmod(1).

You probably want to do something like this:

chmod -R a+rX *

find . -type d -print0 | xargs -0 chmod 755

find . -type f -print0 | xargs -0 chmod 644

Note the -print0 and -0 options make it work with files with whitespace
in their names.

Look into "find", specifically the "-exec" switch.

Not sure of the exact syntax, but you can specify it to list all
files/directories seperately, then execute a command on them, eg.
"chmod 666".

Look at find's -type and -exec options, e.g. find ./ -type d -exec \
chmod 0700 {} \; This saves a ton'o'time

Actually, most people these days would rather use xargs:
find . -type d |xargs chmod 0700

saves a lot of intermediate processes, and is simpler to remember than
the barbaric -exec syntax.

Symbolic modes are often very handy with chmod -R, especially the magic +X.
