WARNING Retry connecting to CmdAgent@10.2.4.104, count 1

[sk]

Hi

Faban is giving this error.
I verified that ssh is enabled on both master and agent and they are
able to login without password.
But I still see this issue while scheduling a run.

Any pointers will be helpful ?

Thank you

ssh can't execute commands on the remote system. Can you please try by
hand (I remember it was ssh user@system command)? Thanks.

-Akara

[sk]

Thanks Akara.
I tried it already and both the machines are able to ssh without
password.
Any other suggestions ?

Thanks

Did you try with command? Thanks.

-Akara

[sk]

Yes I did and I am able to login without password.

Does the command run properly? For instance:

ssh user@host ls

-Akara

[sk]

Yes it does.

Hmmm, hard to support case here. Why won't it get through from the harness?

-Akara

[sk]

Yes, thats why I had to post it here.
Any other thing, I can check here?

Thanks

This is really one of the hardest issues to debug. You can try turning on the FINEST level of logging (by setting com.sun.faban.harness.level=FINEST in config/logging.properties) and see if you can get any additional debug messages that may help.

hi,

don't know if you have resolved it by now. i faced similar errors before. problem was hostname resolution in /etc/hosts. When faban client daemon tried to connect to master it used the faban-master's hostname and resolved it to a stale ip addr. make sure the hostnames of faban-master/clients can be resolved correctly and their /etc/hosts is up-to-date. hope this helps!

If you are still facing this issue then hopefully it is caused by one of the issues I encountered below:

1. The hostname for either the agent or the master is not able to resolve to an IP address by either the agent or the master.  For example, if running hostname on the master yields the name Server1 then the agent needs to have Server1 defined in /etc/hosts or be able to perform DNS lookup for Server1. The same is true for the Master communicating with the agent based on whatever name you put into the <fa:hostConfig> as well as the agents hostname.
   
2. Re-run makeagent from the master and deploy it to the agent. I ran into problems when the the agent was not using the same version of jars as the master (this is probably because I was running a custom build of Faban but it is worth trying).
   
3. Make sure you don't have other faban processes running which are already communicating with the agent. The agents do not appear to support multiple masters. Restarting the agents and the master might help put the system in a known state.
   
4. Make sure the hostnames are already a known host and that the shh command is not asking for verification of the host key. I did this by sshing to all the host names from one machine then copying over the known host files to the rest of the environment.

Let us know if you are able to connect to the agent or are still experiencing errors.

Though ssh is working without asking for pasword and host names are resolvable. I face the same issue while running faban. Is this issue solved ? if yes , what was the solution
