Set an ftp login banner which displays the acceptable usage policy. Rationale: The message in banner.msg is displayed for FTP logins. Banners display necessary warnings to users trying to gain unauthorized access to the system and are required for legal purposes. The recommendation is to set the banner as: 'Authorized uses only. All activity will be monitored and reported'. The content may be changed to reflect any corporate AUP.
Solution
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 Default Value: %s FTP server (%s) ready. Additional Information: Another way to install a banner is to create /etc/ftpaccess.ctl with the following contents: herald: /etc/ftp_banner Then create the file /etc/ftp_banner and write something to it. The banner appears before authentication: print 'Authorized uses only. All activity may be monitored and reported.' >/etc/ftp_banner chmod a-wx /etc/ftp_banner ftp localhost Connected to loopback. 220-Authorized uses only. All activity may be monitored and reported. 220 aix71tl5sp3 FTP server (Version 4.2 Fri Apr 6 19:34:30 CDT 2018) ready. Name (localhost:root):
