H.323 User's Manual I. Linux™ Operating System Installation for the OSN Server
Version 5.0 441 December 2006
I.5.5 Additional RedHat™ and Fedora™ Installation Notes (7)
Please refer to the following notes for the remaining part of the installation.
1. Select LILO as your bootloader where possible, otherwise select GRUB.
2. It is recommended that you disable the firewall when prompted (select “No Firewall”).
3. In case you forget to disable the firewall during the installation and want to do it after
the installation, run the following command:
/usr/bin/redhat-config-securitylevel-tui --quiet –disabled
4. It is recommended that you assign a static IP address to your Mediant 1000. So
when the installation has been completed, you will be able to create an SSH remote
connection and continue the post-installation configuration.
5. During the bootloader configuration (after you selected which bootloader you want to
install), you will be prompted to provide additional text to be appended to the kernel.
Ensure that the installation (grub-installer or lilo-installer) recognizes the serial
console and contains the following text:
console=ttyS0,115200
6. If there is no text (i.e. the installer did not recognize the serial console), then insert the
following:
text console=ttyS0,115200
7. Once the installation has been completed, you will be prompted to re-start the Mediant
1000.
Note: If the installed kernel is version 2.6 or later (Fedora Core 4 or later, RedHat
Enterprise 4 or later) then refer to the Post-installation Notes for Kernels
2.6+, below.
I.5.6 Post-installation Notes for Kernels 2.6+ (Fedora™ Core 4+ and
RedHat™ EL 4+): (3 Notes)
1. When the Mediant 1000 is re-booting and after the BIOS phase, there is a bootloader
phase (GRUB or LILO) which starts uncompressing and loading the kernel. After the
kernel is loaded the services will start. While the services are loading and the
message “Press ‘I’ to enter interactive startup” appears, press “I”.
2. Once the hardware has been detected, you will be prompted whether to start each
service. For the syslog service, select “N” (in order NOT to load it).
3. After you login (either serially or using SSH) to the Mediant 1000, you should disable
the syslog service from being started during system startup. To do this, you have to
disable the S**syslog file located in both /etc/rc3.d and in /etc/rc5.d directories. The
file is usually called S12syslog.
4. Rename it to K12syslog with the following command.
mv S12syslog K12syslog
