Command
Description
Port
The IP port on which the service runs. If no port should be
defined, this field must be left empty. In direct routing or tunneling
mode, the respective port and service must correspond
Weight
This value defines the weighting of the real server in the sync.
Group. The higher the weighting the more inquiries will be sent to
the real server. Servers that should not receive anymore new
inquiries (e.g. during maintenance work) will be provided with a ‘0’
weighting.
If all inquiries should be simultaneously sent to all real servers,
then all servers must have the same weighting. The weighting has
a range 0 - 65535. (Default: 1)
Healthcheck
None
No health check will be made
TCP
The health ckeck will be carried out via TCP with the
following value
HTTP
The health check will be carried out via HTTP with
the following value
SSL
The health check will be carried out via SSL with the
following value
User
Defined
The health check will be carried out via a function,
which must deliver 0 or -1 as value
Connect Port
This value defines the TCP port, used for healthcheck.
5.18.7 Load Balancer Virtual Servers
Command
Description
IP Address
The IP address under which the virtual server can be reached.
Port
The IP port of the virtual server.
A port with address ‘0’ is only
valid, when the service is persistently specified. In this case it is a
wild card port, to which connections to every port are allowed.
Firewall Mark
This value is a firewall marking,
an integer value greater than ‘0’,
which implies a virtual service rather than an address, a port and
a protocol (UDP or TCP). The marking of packets with a firewall
marking is configured with the
–m | --marking option from iptables.
It can be used to create a virtual service, which will be associated
with the same real server to adapt a number of IP addresses,
ports and protocol triplets.
Firewall marked virtual services provide a comfortable method of
grouping different IP addresses, ports and protocols in one single
virtual service. This is useful for a simplified configuration, when a
large number of virtual services is required, and group persistant
is more important than many multiple virtual services.
Check Intervall
This value defines the time in seconds, which lies between the
individual checks of the real servers.
Persistence Timeout
This value defines the time in seconds that a built-up connection
is attached to an existing server. This option is meaningful in
connection with protocols such as SSL or FTP, because it is
important that the clients are continually connected with the same
real server.
