Modified use of SYST requests ----------------------------- The legacy mode, be it with 'auto-login' or not, was to issue immediately a SYST request to the server, expecting information as to the 8-bit capabilities of the host. Since some FTP servers still are built to reject such early requests, until a valid user had been established with the client side, the old behaviour caused annoying error response. These could even disturb the use of intermediary proxy servers. As of package 'ftp_0.17-25' this behaviour has been intention- ally changed, sending SYST only with auto-login, or when issuing the commands 'user' and 'system'. A code analysis could uncover no ill effects of this step. Keep in mind that other FTP client software continue the legacy mode, such as OpenBSD, while yet others have removed it, like FreeBSD. Still others issue a SYST request, but suppress any returned reject message. The client available as 'inetutils-ftp' shows this latter behaviour.
