Metapsloit exploits

[conspiracy565]

Hi all i'm currently undertaking a project that involves exploiting a metapsloitable 2 machine and a windows XP machine running SP3, however the findings that i have found are that there are limited resources available when using metapsloit as there seems to be many step by step guides of how to complete an exploit but not enough information regarding troubleshooting.

Do you think it would be beneficial to learning to explain more about each step of an exploit in terms of what each command does and if an exploit fails for there to be more information available about why it fails and workarounds for how to solve such problems.

For instance when trying to exploit Windows XP with the popular ms08_067_netapi exploit the results for my conducted test just returned "Exploit Completed, but no session was created"

Any feedback regarding this would be most welcome.

Thanks.
