The 'ping' component continuously sends ICMP Echo or UDP requests to a given
IP host and waits for the corresponding ICMP Echo or UDP replies. For each
successfull ICMP Echo or UDP handshake it prints a short statistic. The ICMP
data field gets filled with the letters of the alphabet ('a' to 'z') repeatedly.
Configuration
~~~~~~~~~~~~~
This is an example configuration of the component which shows the default
value for each attribute except 'config.dst_ip' and 'config.interface':
! <config interface="10.0.0.72/24"
! dst_ip="10.0.0.24"
! dst_port="50000"
! protocol="icmp"
! period_sec="5"
! verbose="no"
! count="5" />
This is a short description of the tags and attributes:
:config.interface:
Optional. IP address and subnet of the component. If not set, the component
requests and maintains the IP configuration via DHCP.
:config.gateway:
Optional. IP address of the gateway of the IP subnet.
:config.dst_ip:
Mandatory. IP address of the target host.
:config.period_sec:
Optional. Length of send interval in seconds.
:config.verbose:
Optional. Toggles wether the component shall log debugging information.
:config.count:
Optional. After how many successful pings the component exits successfully.
:config.dst_port:
Optional. Destination port resp. ICMP query ID to use.
:config.protocol:
Optional. Protocol to ping with. Can be one of 'icmp', 'udp'.
Sessions
~~~~~~~~
This is an overview of the sessions required and provided by the
component apart from the environment sessions:
* Requires one Timer session.
