rootpw=

des-crypted-password

The rootpw=des-crypted-password argument enables SSH remote access on a PXE boot
without passing a plain text password across the network.

Create des-crypted-password using the following perl script:

# perl -e

’print crypt("password","42"). "\n"’

The string output is what to supply after the rootpw=argument.

vncauth=

hex-string

This argument enables a password for VNC access.

The remote VNC authorization file is eight binary bytes. You create those eight bytes with
vncpasswd

and then convert them to a hex-string to be entered here.

Create the hex-string using the following commands:

# vncpasswd /tmp/vncauth

# od -t x1 /tmp/vncauth | awk

’/0000000/ \

{print $2 $3 $4 $5 $6 $7 $8 $9}

The string output is what to supply after the vncauth=argument.

ptextpass=

password

The ptextpass=password argument provides a way of passing a plain text password that is
to be used for both the root password and the VNC password.

Using a System Console

Typically the system console displays a splash screen during an unattended network installation
that prevents you from viewing the console messages. To dismiss the splash screen and view the
console messages, press the Esc key.

Using a Virtual Console or Secure Shell (SSH) Connection

The installation interface runs a Linux kernel and provides virtual console access. To access the
virtual console, press Ctrl-Alt-F2. You can also use Ctrl-Alt-F3 and Ctrl-Alt-F4 for additional
console screens.

Before logging into a virtual console, you must set a root password as a boot argument to the
installer. For more information see

“Set Up Passwords for Root and Virtual Access” on page 55

.

After you have established a connection to a virtual console, you can determine the VNC server
IP address and view the standard log files. Alternatively, you can also establish a SSH
connection through a serial console using the VNC IP address.
