Installation guide

Only one send sequence is allowed in this field, and it can only contain printable, ASCII

characters as well as the following escape characters:

• \n for new line.

• \r for carriage return.

• \t for tab.

• \ to escape the next character which follows it.

Expect

Enter a the textual response the server should return if it is functioning properly. If you wrote

your own sending program, enter the response you told it to send if it was successful.

Tip

To determine what to send for a given service, you can open a telnet

connection to the port on a real server and see what is returned. For instance,

FTP reports 220 upon connecting, so could enter quit in the Send field and 220

in the Expect field.

Warning

Remember to click the ACCEPT button after making any changes in this panel.

To make sure you do not lose any changes when selecting a new panel.

Once you have configured virtual servers using the Piranha Configuration Tool, you must

copy specific configuration files to the backup LVS router. See Section 7, “Synchronizing

Configuration Files” for details.

7. Synchronizing Configuration Files

After configuring the primary LVS router, there are several configuration files that must be

copied to the backup LVS router before you start LVS.

These files include:

• /etc/sysconfig/ha/lvs.cf — the configuration file for the LVS routers.

• /etc/sysctl — the configuration file that, among other things, turns on packet forwarding in

the kernel.
