Ensure that the bos.msg.en_US.net.tcp.client fileset is installed: lslpp -L "bos.msg.en_US.net.tcp.client" NOTE: If the fileset is not installed, install it from the AIX media or another software repository. The fileset should reflect the language used on the server. Once installed set the ftp AUP banner: dspcat -g /usr/lib/nls/msg/en_US/ftpd.cat > /tmp/ftpd.tmp sed "s/\"\%s FTP server (\%s) ready.\"/\"\%s Authorized uses only. All activity may be monitored and reported\"/" /tmp/ftpd.tmp > /tmp/ftpd.msg gencat /usr/lib/nls/msg/en_US/ftpd.cat /tmp/ftpd.msg rm /tmp/ftpd.tmp /tmp/ftpd.msg
