# TCP Router testing
Building an app to deploy to Cloud Foundry that listens to a certain port and reads the input. In a couple versions.
## TCP Routing on CF
### Enabling TCP Routing
https://docs.cloudfoundry.org/adminguide/enabling-tcp-routing.html
In TAS, check the appropriate boxes in OpsMan. Optionally, increase the allowable port range to include 48556.
### Adjust router groups
CF TCP Routing by default delivers TCP traffic from any source to port 8080. This can be changed.
https://docs.cloudfoundry.org/devguide/custom-ports.html
`cf curl /routing/v1/router_groups/0d3d58c3-9f3f-4e3b-4df0-8cecc1c5a37a -d @update_router_group.json -X PUT`
## Running Locally
Start with
`mvn clean spring:boot run`
then
`nc localhost 8080 < testfile.bin`
### Log example
```

```
## Deploying to CF
### Create Domain
`cf create-shared-domain test.tcp.tas.lab.sampsoftware.net --router-group default-tcp`
Ensure that the router group is updated to use the ports required if using custom ports. By default, Diego will deliver traffic from any TCP Router port to port 8080 on the container.
### CF Push
```
mvn clean package && cf push
cf logs very-simple-tcp-server
cf routes
nc [IP of TCP Router] 30000 < testfile.bin
```
