Load testing and Tsung - Does it work on ec2?

Question

I have tried to get tsung to work on ec2 but to no avail. Is this why people tend to use jmeter? Tsung works of a single host but not at all on ec2. 1) I have using the same zone thus using the private dns and ip on ec2. 2) I create a master and usig the following to create a ssh key on the master. ``` cd /home/ubuntu/.ssh; ssh-keygen -f id_rsa -t rsa -N '' ``` 3) Then, on eash of the slaves I place the generated key into the auth keys. ``` /home/ubuntu/.ssh/authorized_keys ``` 4) On the slaves my /etc/hosts file looks like this per the docs. ``` xxx.xxx.xxx.xxx ip-10-xxx-xxx-xxx ``` 4) On the master I run sudo tsung start. I can ssh into the slaves without a password. in the log file I get this error: ``` =INFO REPORT==== 28-May-2012::03:51:12 === ts_config_server:(0:<0.76.0>) Can't start newbeam on host 'ip-xxx-xxx-xxx (reason: timeout) ! Aborting!]] ``` 5) The documents provides tips on to resolve but those tips are by no means clear at all since I an still receiving this error. Bu…

Accepted Answer

On the master machine do the follwoing:

```
cd /home/ubuntu/.ssh
ssh-keygen -f id_rsa -t rsa -N ''
eval `ssh-agent`
ssh-add ~/.ssh/id_rsa

for each slave:
    ssh-keyscan EC2_PUBLIC_DNS_NAME | tee -a ~/.ssh/known_hosts
```

or use the privite dns name

or

```
#        You can add this in .ssh/config on the master node:
#        >
#        > Host *
#        >        StrictHostKeyChecking no
```
