Add com1=115200,8n1 here. Make sure you enter zeroes, not lowercase letter
Os and that you enter ones, not lowercase letter Ls.
2
The backslash (\) in this example indicates line continuation. Do not enter a
backslash character in your file.
3
Add console=ttyS0 here. Make sure you enter the number zero, not the letter
O.
6.
Save your changes and exit the text editor.
7.
After all three files have been modified, reboot the system for the changes to take effect.
After you make these changes, all system start up and shut down messages are directed to the
serial console you selected and are not directed to the graphics display. Therefore, the system
boot appears to be different. This is expected and normal behavior.
To view the system console, use the CMF utilities on the CMS. For more information about using
CMF, see
4.4.6 Turning on password authentication
This task is required only on managed systems that are installed with a supported version of
SLES, but you did not use a configuration file derived from the Insight Control for Linux
installation templates to install its OS. Otherwise, skip this task.
If a managed system is installed with SLES, password authentication must be turned on in order
to set up the HP SIM SSH keys
When you use Insight Control for Linux tools to install SLES on a managed system, Insight
Control for Linux automatically edits the /etc/ssh/sshd_config file and turns on password
authentication in this file.
However, if you did not use the Insight Control for Linux tools to install a SLES OS on a managed
system, you must manually edit the /etc/ssh/sshd_config file to turn on the
PasswordAuthentication
attribute as shown in
.
Example 4-1 Excerpt from sample /etc/ssh/sshd_config file
# To disable tunneled clear text passwords, change to no here!
#PasswordAuthentication yes
#PermitEmptyPasswords no
PasswordAuthentication yes
