UPGRADE to version 1.1.2

1) Upgrading from 1.1.1

If you are upgrading from version 1.1.1, there are only two changes that
should be done regarding configuration.

 - Change the home directory for the user root from '/' to '/root' in
   the file /etc/passwd..

 - In the file pslave.conf, ports configured as protocol "telnet" or
   "socket_server" must have their parameter "socket_port" configured
   with a valid value. If the socket_port parameter is not configured,
   then 23 will be used.

This new version brings the following new features:

 - Userauto : default user name for a port (profile TS only).

 - Two new parameters for Data Buffering in order to:
    . Write Data buffering into a NFS file
    . Disable DB menu presentation.

 - Changing in the portslave authentication process.

For more information about these new features, please read the up-to-date
Cyclades-TS documentation.

2) Upgrading from 1.1.0

If you are upgrading from version 1.1.0 make sure that there is no
parameter initchat for ports configured as socket_server or socket_ssh. Also,
Change the home directory for root as described in the previous section.

This new version brings two new features:

 - Boot parameters configuration: using the program bootconf the user can 
   configure all boot parameters including the Fast Ethernet operation
   mode (100bt Half/full, 10bt half/full, or auto negotiable)

 - Port access restriction: a new parameter s<nn>.users was created in order
   to define a group (set) of users that can or not can access a serial port.

3) Upgrading from version 1.0.x  

Many of the packages of TS version 1.0.1 were updated. So, If the user has 
a TS running a 1.0.x version, special care should be taken regarding 
configuration.

In this document we assume that the TS is already running the new Linux
Kernel Image (1.1.2) and that it will be the version used from now on.
  
For those who are new to Linux/Unix, we recommend to read appendix A from
the Cyclades TS Manual.

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

    echo 0 > /proc/flash/script
    reboot
 
Or the user must perform the steps listed below:

1 - The Openssh needs a new configuration file: /etc/ssh/sshd_config. The
    user must copy /etc/ssh/sshd_config.save over /etc/ssh/sshd_config and
    and redo his own changes, if any, in /etc/ssh/sshd_config.

2 - The portslave configuration file /etc/portslave/pslave.conf has many
    parameters created, changed or deleted. The user can just copy the file
    /etc/portslave/pslave.save over /etc/portslave/pslave.conf and redo his
    own configuration or perform the steps 2.1 to 2.5.

    PS. The prefix <nn> means "all", "s1", "s2", ...  and so on.

2.1 The ppp option "uselib", that is into the parameters <nn>.autoppp and
    <nn>.optppp, must be changed to "plugin".

2.2 A new parameter <nn>.utmpfrom was created. Its default value is
    "%p:%P.%3.%4". This is the information that portslave will write in the
    "/var/run/utmp" file, where:
      
    %p - Port number
    %P - Protocol
    %3 - Third byte of remote ip
    %4 - Fourth byte of remote ip

2.3 The new portslave has only one modem string parameter "<nn>.initchat".
    The user should get a sample of this parameter in the new portslave
    configuration file /etc/portslave/pslave.save.

2.4 The following parameters should be deleted from the file:

    <nn>.waitfor
    <nn>.answer
    <nn>.aa
    <nn>.checkchat
    <nn>.checktime
    <nn>.stripname.

2.5 The parameters "<nn>.stopbit" and "<nn>.servername" must be respectively
    replaced with "<nn>.stopbits" and "<nn>serverfarm".

3 - The user must copy /etc/config_files.save over /etc/config_files 
    and make his own changes again, if any, in /etc/config_files.

4 - The new TS version 1.1.2 has a ntpclient that can be activated by the
    script "/bin/ex_ntpclient".

5 - Before continue, make the changes that are stated in the sections
    Upgrading from versions 1.1.0 and 1.1.1
 
6 - If the user did not make any changes in the files /etc/inittab and
    /etc/rc.sysinit he must skip this step. If he had changed /etc/inittab, 
    he must copy /etc/inittab.save over /etc/inittab and make his own changes
    again. If he had changed /etc/rc.sysinit he must copy /etc/rc.sysinit.save 
    over /etc/rc.sysinit and make his own changes again.
    After saving the configuration (by running saveconf) and rebooting the TS, 
    the upgrade is done.

7 - To run the new configuration and save it into flash the user must execute
    the commands:

    signal_ras hup
    saveconf
