Remote agent failing to connect to server

[Bobby Tait]

Bamboo: 6.9.2 build 60911

Server: Windows 10 Pro on PC

Agent: Windows 10 Pro on Azure VM

I'm assuming I've configured the VM networking incorrectly. I've tried configuring both the server and VM, with no luck. I'd appreciate any guidance. 

atlassian-bamboo-agent.log says this, repeatedly:

Hi @Bobby Tait

I can't help you with Azure configuration, but with Bamboo. What I see from your logs is that the Bamboo agent is not getting responses from the server and that is probably happening because your agent is trying to reach the Bamboo server using wrong or unreachable address.

We need to make sure your Bamboo server is reachable from the VM running the agent. I guess you already know that. You can use this page as a reference on troubleshooting: Troubleshooting Remote Agent - Atlassian Documentationtip/resting. It has some suggested commands to check the connectivity.

The same page will talk about the connections needed between the server and agent HTTP and JMS ones. In your case, the HTTP one is failing. Once that is working your agent will try the second one which will involve reaching the Bamboo server broker configured in <Bamboo_Home>/bamboo.cfg.xml. 

Please keep us posted on your findings and possibly other questions, to solve this problem, as your investigation evolves.

[Bobby Tait]

Thanks for your reply, @Daniel Santos; got sidetracked for a couple of days. I have seen that page and attempted some of the steps to no avail. This is my first time administrating a Bamboo server and working with an Azure VM, and was hoping somebody had already made this work. Continuing to dig and experiment.

More specifically, I can ping the server from the agent.

However, I am stuck trying to get it to telnet into it.

Hi @Bobby Tait,

That is ok, take your time.

This is my first time administrating a Bamboo server and working with an Azure VM, and was hoping somebody had already made this work. Continuing to dig and experiment.

I can't help with the Azure configuration, unfortunately, but I can help with the troubleshooting.

More specifically, I can ping the server from the agent.
However, I am stuck trying to get it to telnet into it.

From what I can get, the agent is not able to reach the ports of the server, but it can resolve the server. It might be the case that the server firewall is not allowing public access to the HTTP and JMS (broker) ports.

[Bobby Tait]

That is my guess, too. My test "server" in this case is my development laptop. I opened the ports up, but still no love. I'm thinking the company firewall is blocking the traffic. IS hasn't gotten back to me yet about that.

[Daniel Santos]

I got it! You are on the right track. If your remote agent is not able to reach the server there is no deal. Let's wait for their feedback.

[Bobby Tait]

As we thought, IS is very particular about who or what accesses their servers. Holes need to be drilled through our corporate firewall in order for this to work. Thank you for the additional information, Daniel. :)

You are welcome! =]
