Vihung's questions

I am setting up a test environment, made up of various Linux boxes, and I have the need to launch an instance of Firefox on a remote machine via ssh.

The remote machine has Ubuntu Desktop (11) and Firefox installed.

The source machine is a Continuous Integration server and it creates an ssh session to the remote machine from a non-GUI environment. It then runs a script, which tries to launch Firefox on the remote machine.

However, since the ssh session is a from a non-GUI environment, there is no display.

Is it possible to have a headless X-windows display? i.e. a virtual display in the remote environment for Firefox to run in? What options do I have?

Is it possible to configure sendmail to accept all outbound email but to not send it out? Either it can just log them to be read later, or better yet, if it can be configured to send ALL outbound mail to a preconfigured recipient (regardless of what is specified in the email).

We work on developing applications for e-commerce. Our development environments are Ubuntu Desktop (11.10).

We run a full application stack locally on each desktop - web server, application server, database etc.

Our application sends out email when certain events occur.

We do not actually want the email to be sent to the intended recipient, because this is not from a production environment.

We would like the application to think that the sending of email has been successful.

We would like to see the email, post-facto, that gets sent out.

Note, we are on Ubuntu. If not sendmail, then maybe some other mail server?
