3.9.1. TUX FTP Server Security Features
The following are security features of the TUX FTP Server:
Because TUXdoes not start per-client processes, thememory allocation overhead for each
FTP client logged in is less than 10 KB. This allows thousands of parallel connections.
Paranoid parser and paranoid command-evaluation.
Chroots to docroot.
Never starts any external userspace process. All FTP functionality is done in a approxi-
mately 900 lines C module, in the kernel.
Even in kernel mode the TUX FTP Server drops all priviledges and switches to uid and
group nobody.
Only themost trivial globbing (mget *) supported, and no recursion support.
