Chapter 9. Host Setup for a Small UML Server


After having talked about UML almost exclusively so far, we will now talk about the host. This chapter and the next will cover setting up and running a secure, well-performing UML server. First we will talk about running a small UML server, where the UML instances will be controlled by fairly trusted people, such as the host administrator or others with logins on the host. Thus, we won't need the same level of security as on a large UML server with unknown, untrusted people inside the UML instances. We will have a basic level of security, where nothing can break out of a UML instance onto the host. We won't be particularly paranoid about whether network traffic from the UMLs is originating from the expected IP addresses or whether there is too much of it. Similarly, we will talk about getting good performance from the UML instances, but we won't try to squeeze every bit of UML hosting capacity from the host.

All of these things, which a large UML hosting provider cares about more than a casual in-house UML user does, will be discussed in the next chapter. There, we will cover tougher security measures, such as how to protect the host even if a user does somehow manage to break out of a UML instance and how to ensure that UML instances are not spoofing IP addresses or sending out unreasonably large amounts of traffic. We will also discuss how to log resource usage, such as network traffic, in that chapter. But first, let's cover what more casual users want to know.
