Description of Problem: From the ftpd manpage: "The -I option disables the use of RFC931 (AUTH/ident) to attempt to determine the username on the client." I have tried this setting in /etc/xinetd.d/wu-ftpd on several releases (versions 2.6.1-0.6x.21 through wu-ftpd-2.6.1-20 on RedHat 6.1 through RedHat 7.2) and it does not appear to work. The server still generates AUTH IDENT requests and hangs for up to 30 seconds, waiting for a reply. My only workaround was to set an outbound firewall rule to "REJECT" any packets to port 113. Version-Release number of selected component (if applicable): 2.6.1-0.6x.21 through 2.6.1-20 on wu-ftpd How Reproducible: 100% Steps to Reproduce: 1.add a -I to the line "server_args = -l -a" and restart xinetd 2.make an ftp connection to the server 3.watch for IDENT requests (port 113). If it receives no response, the ftp connection will hang for up to 30 seconds Actual Results: Depending on whether host responds with ident, either a connection, or up to a 30 second delay. Expected Results: A snappy and short connect time. Additional Information:
Please use vsftpd instead. wu-ftpd is not maintained anymore.
