Hello collective wisdom, We have here: * Server version: 1.3.5~rc3-2.1ubuntu2.1 * Client version: ncftp-3.2.5-7.el7.x86_64 My concern is the response to “rstatus” command from ncftp which shows the name of the server software: ftp> debug <— Turned on debugging to see what command the client sends. Debugging on (debug=1). ftp> rstatus ---> STAT <— STAT is sent 211-Status of ‘ProFTPD’ <— somehow the client knows it is ProFTPD 211-Connected from XXX.XXX.XXX.XX (XXX.XXX.XXX.XX) 211-Logged in as ftp 211-TYPE: ASCII, STRUcture: File, Mode: Stream 211-Total bytes transferred for session: 126 211-No data connection 211 End of status ftp> stat I consider this a security risk. My configuration has these directives among the rest: #ServerName "Debian" ServerIdent on "--------------------------------------------------------------------------------" Any idea when exactly the server responds to the client with “ProFTPD” string? Is it immediately in response to STAT or some time earlier in the session? How to eliminate? — Regards, Michael ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ ProFTPD Users List <[email protected]> Unsubscribe problems? http://www.proftpd.org/list-unsub.html
