UPGRADE to version 1.1.0

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 (1.1.0) 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 1.1.0 has a ntpclient that can be activated by the
    script "/bin/ex_ntpclient".

5 - 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.

6 - To run the new configuration and save it into flash the user must execute
    the comands:

    signal_ras hup
    saveconf
