Example: RI Configuration of SAProuter
The following example shows a possible configuration of the SAProuter for using Reverse Invoke.
Here both the RI client and the RI server are SAProuters.
The client SAProuter has opened external port 4001. The client SAProuter accepts connection requests through this port, which it then forwards to the server SAProuter. An RI connection should be opened between the two SAProuters.
The table below shows how the two SAProuters can be configured for this.
|
Configuration Task |
Client |
Server |
|---|---|---|
|
Start command |
saprouter -i c f1 -S 4001 -R rt1 |
saprouter -i c f2 -S 4002 -R rt2 |
|
Configuration file name |
cf1 |
cf2 |
|
Content of the configuration file |
client = true client_service= 5001 |
server = true client_hostname = 10.18.0.1 client_service = 5001 reg_service = 5002 |
|
Content of saprouttab |
P * 10.18.0.2 5002 With this rule the client permits connections from each source IP address with destination 10.18.0.2:5002. |
P 10.18.0.1 * * With this rule the server permits connections from client 10.18.0.1 to each destination (IP address/port). |
The following route can be used to connect across the two SAProuters:
/H/10.18.0.1/S/4001/H/10.18.0.2/S/5002/H/<dest host>/S/<dest service>
For more information about the SAProuter status, call saprouter -l. In this example the output from the call would look like:
