It allows you to do a large +part of the installation over the network via SSH. The use of the +network implies you will have to perform the first steps of the +installation from the console, at least to the point of setting up +the networking. (Although you can automate that part with +<xref linkend="automatic-install"/>.) + +</para><para arch="not-s390"> + +This component is not loaded into the main installation menu by default, +so you have to explicitly ask for it. + +If you are installing from CD, you need to boot with medium priority or +otherwise invoke the main installation menu and choose <guimenuitem>Load +installer components from CD</guimenuitem> and from the list of +additional components select <guimenuitem>network-console: Continue +installation remotely using SSH</guimenuitem>. Successful load is +indicated by a new menu entry called <guimenuitem>Continue +installation remotely using SSH</guimenuitem>. + +</para><para arch="s390"> + +For installations on &arch-title;, this is the default method after +setting up the network. + +</para><para> + +<phrase arch="not-s390">After selecting this new entry, you</phrase> +<phrase arch="s390">You</phrase> will be asked for a new password +to be used for connecting to the installation system and for its +confirmation. That's all. Now you should see a screen which instructs +you to login remotely as the user <emphasis>installer</emphasis> with +the password you just provided. Another important detail to notice on +this screen is the fingerprint of this system. You need to transfer +the fingerprint securely to the <quote>person who will continue the +installation remotely</quote>. + +</para><para> + +Should you decide to continue with the installation locally, you +can always press &enterkey;, which will bring you back to +the main menu, where you can select another component. + +</para><para> + +Now let's switch to the other side of the wire. As a prerequisite, you +need to configure your terminal for UTF-8 encoding, because that is +what the installation system uses. If you do not, remote installation +will be still possible, but you may encounter strange display +artefacts like destroyed dialog borders or unreadable non-ascii +characters. Establishing a connection with the installation system +is as simple as typing: + +<informalexample><screen> +<prompt>$</prompt> <userinput>ssh -l installer <replaceable>install_host</replaceable></userinput> +</screen></informalexample> + +Where <replaceable>install_host</replaceable> is either the name +or IP address of the computer being installed. Before the actual +login the fingerprint of the remote system will be displayed and +you will have to confirm that it is correct. + +</para><note><para> + +If you install several computers in turn and they happen to have the +same IP address or hostname, <command>ssh</command> will refuse to connect +to such host. The reason is that it will have different fingerprint, which +is usually a sign of a spoofing attack. If you are sure this is not the +case, you will need to delete the relevant line from +<filename>~/.ssh/known_hosts</filename> and try again. + +</para></note><para> + +After the login you will be presented with an initial screen where you +have two possibilities called <guimenuitem>Start menu</guimenuitem> and +<guimenuitem>Start shell</guimenuitem>. The former brings you to the +main installer menu, where you can continue with the installation as +usual. The latter starts a shell from which you can examine and possibly +fix the remote system. You should only start one SSH session for the +installation menu, but may start multiple sessions for shells. + +</para><warning><para> + +After you have started the installation remotely over SSH, you should +not go back to the installation session running on the local console. +Doing so may corrupt the database that holds the configuration of +the new system. This in turn may result in a failed installation or +problems with the installed system. + +</para><para> + +Also, if you are running the SSH session from an X terminal, you should +not resize the window as that will result in the connection being +terminated. + +</para></warning> + + </sect3> |
