LINUX - RDS-STRESS COMMAND TESTS TO TEST RDS CONNECTIONS BETWEEN TWO HOSTS OVER A SPECIFIC PORT

Following are steps for running RDS stress test between Linux hosts

On the host which you want to act as server run below command. 
 
# rds-stress -v -p 5050 
 
With above command on host acting as server we are starting rds-stress with verbose option and on port 5050. You will see below line where it says it is waiting for connections. 
 
        waiting for incoming connection on 0.0.0.0:5050 
 
On the client from which you want to connect to the client run rds-stress command as follows to connect to server over port 5050. 
 
rds-stress -r 172.XX.0.49 -s 172.XX.0.1 -p 5050 
 
In this case the IP for -r will be the local IP on the client from which you want to do rds-stress test. IP for -s will be the server ip which is listening for rds-stress test connections. 
 
With rds-stress test running you will be seeing outputs as follows: 
 
On client you will see below traces
 
rds-stress -r 172.XX.0.49 -s 172.XX.0.1 -p 5050
