It appears these clients depend on ftpd returning a 550 error when attempting to RETR a directory. ftpd returns the raw directory which the client downloads as a binary file instead of displaying a directory listing. These clients do display directory listings correctly when logged in as a guest user (anonymous), since ftp returns a 550 error when RETRing a directory when logged in as anonymous. >How-To-Repeat: >From Mozilla, go to a FTP URL that refers to a directory and is not anonymous, e.g. ftp://someuser@some.site/some/dir/ >Fix: The problem was introduced in revision 1.62.2.46 of src/libexec/ftpd/ftpd.c that allows non-guest users to download special files. One fix would be to change if (guest) { to if (guest || S_ISDIR(st.st_mode)) { which would make ftpd always return a 550 error when attempting to RETR a directory. >Release-Note: >Audit-Trail: >Unformatted:
