  2. Starting Communications Server automatically: Type the following command, then press Enter:
    lsitab sna
  3. If the sna line is not found, type the following command, then press Enter:
    mkitab "sna:2:wait:/etc/rc.sna > /dev/console 2>&1 #start   SNA Daemons"

    (There is one blank space between rc.sna and >, and one blank space after >.)

  4. Edit the /etc/rc.sna file.
  5. Find the line that reads #/usr/bin/snaadmin init_node, and remove the # (which is a comment indicator).

  7. Save the file.
  8. Shut down the AIX system using the shutdown -Fr command and restart it to make the changes take effect.
