/* | |
Testing of some network related lookup functions. | |
The system databases looked up are: | |
- /etc/services | |
- /etc/hosts | |
- /etc/networks | |
- /etc/protocols | |
- /etc/rpc | |
The tests try to be fairly generic and simple so that they work on | |
every possible setup (and might therefore not detect some possible | |
errors). | |
