I do not think you can use ftp's chmod command to change the permissions of a remote directory - especially if you do not own it.

Does the chmod command work for ordinary files?

You can use FTP to CHMOD files and directories. However, fpmurphy is correct in that the FTP user must have the correct permissions to modify the files/directories in the first place.

Cheers,

The ftp protocol does not specify anything about file permissions. Many unix based ftp servers have implemented a site command based chmod facility. Some unix based ftp clients even have a chmod command to invoke the site command. When the server has a chmod facility, it may impose additional restictions beyond what the underlying file systems has. You need to check the docs for that particular server. I have never seen any ftp server fully implement the unix chmod command. Not allowing a ftp based chmod to effect a directory is a common restriction. Disallowing suid, sgid and sticky bits are also very common restrictions..possibly even universal restrictions.
