UPGRADE to version 2.1.2

REMARKS
=======
      . For more information about new features, please read the up-to-date
        Release Notes.

      . For those who are new to Linux/Unix, we recommend reading appendix A
        in the Cyclades ACS User's Guide.

NOTE: Cyclades strongly recommends that the user has read the latest User's
Guide available in Cyclades' ftp site before using this new firmware.


UPGRADING OVERVIEW
==================

The ACS packages may be updated from one version to another. So, if the user
has an ACS running an earlier version, special care should be taken regarding
configuration.

The user can choose to start the configuration from scratch by simply doing:

    echo 0 > /proc/flash/script
    reboot

or, the user must perform all steps from all "Upgrading from <version> actions"
with version numbers equal to or greater than the original version of his ACS.

To run a new configuration and save it into flash the user must execute
the following commands:

    signal_ras hup
    saveconf

The command "saveconf" is equivalent to the Linux command:

"tar -czf /proc/flash/script -T /etc/config_files"

so, double check that all files which have been changed have their names in the
file /etc/config_files.

If any of the files /etc/inittab, /etc/rc.sysinit, or any user's shell script
executed by /etc/rc.sysinit were changed, the ACS must be rebooted for them to
take effect.

Upgrading from 2.1.1 Actions
============================

- The meaning of the parameter DTR_reset in pslave.conf file was changed.
  Please, read the documentation to set it to the proper value.

- The sshd program needs a new configuration file to fix a problem with sftp.
  If the file /etc/ssh/sshd_config was not changed, just replace it with
  the file /etc/ssh/sshd_config.save.  Otherwise the user should merge
  these files.

- The telnet program was moved from /bin to /usr/bin. If you use the protocol
  telnet in PortSlave, you need to change the parameter conf.telnet. 
 
- The /etc/pcmcia/isdn.opts was changed. Copy /etc/pcmcia/isdn.opts.save 
  over /etc/pcmcia/isdn.opts and re-apply your changes, if any. Run 
  "saveconf".  

- The /etc/config_files contains a list of files that are saved to flash
  when you run "saveconf". If you had run "saveconf" with release 2.1.1,
  your /etc/config_files is loaded from the flash and you will not have
  the latest list. Please edit /etc/config_files, add the file listed
  below and run "saveconf":
  /etc/ppp/auth-up


Upgrading from 2.1.0 Actions
============================

- The web user management has changed, and because of that, the file
  /etc/websum.conf has changed. In order to make the web server work, the
  user must do the following steps:
      From the prompt, type
          #cp /etc/websum.conf.save /etc/websum.conf
          #saveconf
          #reboot
      After the reboot, open a browser and point to the ACS IP address. Log
        in as root (password = tslinux).
      Go to the link Web User Management->Users, change the root password and
        create the users, classifying according to the privilege allowed to
        them (root, admin, monitor or user).
      Go to the link Web User Management->Load/Save Web Configuration and click
        the "Save Configuration" button.
      Go to the link Administration->Load/Save Configuration and click the
        "Save to Flash" button.

- The syslog-ng.conf file (syslog-ng configuration) was changed.
  This configuration allows syslog-ng to receive syslog messages from the
  Kernel. The user must copy /etc/syslog-ng/syslog-ng.save over
  /etc/syslog-ng/syslog-ng.conf and make his own changes again, if any.

- The /etc/wireless.opts was changed. Copy /etc/wireless.opts.save over
  /etc/wireless.opts and re-apply your changes, if any. Please also 
  change the file permission of wireless.opts by executing 
  "chmod 600 /etc/pcmcia/wireless.opts". Run "saveconf".

- The /etc/config_files contains a list of files that are saved to flash
  when you run "saveconf". If you had run "saveconf" with release 2.1.0,
  your /etc/config_files is loaded from the flash and you will not have
  the latest list. Please edit /etc/config_files, add the files listed
  below and run "saveconf":
  /etc/pcmcia/isdn.opts
  /etc/mgetty/login.config
  /etc/ppp/auth-up
  /etc/ppp/chap-secrets
  /etc/ppp/pap-secrets
  /etc/ppp/ioptions
  /etc/ppp/options
