[. . . ] Using the boot disk included with the Red Hat Linux boxed set, type linux rescue at the boot: prompt. You then pick an installation method and choose a valid installation tree to load from. · For more information regarding rescue mode, refer to Official Red Hat Linux Customization Guide. 4. 14. 2 Alternatives to YABOOT If you do not wish to use YABOOT, you can also place the kernel directly in a PReP boot partition and boot your Red Hat Linux system from the Open Firmware command line. If you use this method, be sure to include a root= argument at the boot command, eg: boot sd: root/dev/sda2 (if sda2 is your root ("/") partition. 4. 15 Network Configuration If you do not have a network card, you will not see this screen. Please skip ahead to the next section, Section 4. 18, Time Zone Configuration. If you have a network card and you have not already configured your networking, you now have the opportunity (as shown in Figure 4­9, Network Configuration). You may switch between devices (for example, between eth0 and eth1) and the information you provide on each tab will be specific to each device. Choose whether you would like to configure your IP address using DHCP (Dynamic Host Configuration Protocol). If you select Activate on boot, your network interface will be started when you boot. If you do not have DHCP client access or you are unsure what to provide here, please contact your network administrator. Section 4. 16:Firewall Configuration 51 Next enter, where applicable, the IP Address, Netmask, Network, and Broadcast addresses. If you are unsure about any of these, please contact your network administrator. Figure 4­9 Network Configuration If you have a fully qualified domain name for the network device, enter it in the Hostname field. Tip Even if your computer is not part of a network, you can enter a hostname for your system. If you do not take this opportunity to enter in a name, your system will be known as localhost. Finally, enter the Gateway and Primary DNS (and if applicable the Secondary DNS and Ternary DNS) addresses. 4. 16 Firewall Configuration Red Hat Linux also offers you firewall protection for enhanced system security. A firewall exists between your computer and the network, and determines which resources on your computer remote 52 Chapter 4:Installing Red Hat Linux users on the network can access. A properly configured firewall can greatly increase the security of your system. Choose the appropriate security level for your system. Figure 4­10 Firewall Configuration High If you choose High, your system will not accept connections (other than the default settings) that are not explicitly defined by you. By default, only the following connections are allowed: · · DNS replies DHCP -- so any network interfaces that use DHCP can be properly configured If you choose High, your firewall will not allow the following: · · · · Active mode FTP (passive mode FTP, used by default in most clients, should still work) IRC DCC file transfers RealAudioTM Remote X Window System clients Section 4. 16:Firewall Configuration 53 If you are connecting your system to the Internet, but do not plan to run a server, this is the safest choice. If additional services are needed, you can choose Customize to allow specific services through the firewall. Medium If you choose Medium, your firewall will not allow remote machines to have access to certain resources on your system. By default, access to the following resources are not allowed: · · · · Ports lower than 1023 -- the standard reserved ports, used by most system services, such as FTP, SSH, telnet, and HTTP The NFS server port (2049) The local X Window System display for remote X clients The X Font server port (by default, xfs does not listen on the network, it is disabled in the font server) If you want to allow resources such as RealAudioTM, while still blocking access to normal system services, choose Medium. You can select Customize to allow specific services through the firewall. No Firewall No firewall provides complete access to your system and does no security checking. It is recommended that this only be selected if you are running on a trusted network (not the Internet), or if you plan to do more detailed firewall configuration later. Choose Customize to add trusted devices or to allow additional incoming services. Trusted Devices Selecting any of the Trusted Devices allows access to your system for all traffic from that device; it is excluded from the firewall rules. [. . . ] If you hard drive is more than 1024 cylinders, you must create a /boot partition if you want the / (root) partition to use all of the remaining space on your hard drive. C. 3. 4 Other Partitioning Problems If you are using Disk Druid to create partitions, but cannot move to the next screen, you probably have not created all the partitions necessary for Disk Druid's dependencies to be satisfied. You must have the following partitions as a bare minimum: · · · A <PReP Boot> partition of type Linux native A / (root) partition of type Linux native A <swap> partition of type Linux swap Tip When defining a partition's type as Linux swap, you do not have to assign it a mount point. Disk Druid automatically assigns the mount point for you. C. 3. 5 Are You Seeing Python Errors? During some upgrades or installations of Red Hat Linux, the installation program (also known as Anaconda) may fail with a Python or traceback error. This error may occur after the selection of individual packages or while trying to save the upgrade log in /tmp. [. . . ]
