Configurar un PAN (Personal Area Network: espaci de malhum personau) que podera emular ua coneccion Ethernet.
Atau podem aver ua NIC (Network Interface Card) virtuala e puish podem SSH.

- pkg-config
| usage: pkgconf [OPTIONS] [LIBRARIES] | |
| basic options: | explicacions |
| --help | this message |
| --about | print pkgconf version and license to stdout |
| --version | print supported pkg-config version to stdout |
| --atleast-pkgconfig-version | check whether or not pkgconf is compatible |
| | with a specified pkg-config version |
| --errors-to-stdout | print all errors on stdout instead of stderr |
| --print-errors | ensure all errors are printed |
| --short-errors | be less verbose about some errors |
| --silence-errors | explicitly be silent about errors |
| --list-all | list all known packages |
| --list-package-names | list all known package names |
| --simulate | simulate walking the calculated dependency graph |
| --no-cache | do not cache already seen packages when |
| | walking the dependency graph |
| --log-file=filename | write an audit log to a specified file |
| --with-path=path | adds a directory to the search path |
| --define-prefix | override the prefix variable with one that is guessed based on |
| | the location of the .pc file |
| --dont-define-prefix | do not override the prefix variable under any circumstances |
| --prefix-variable=varname | sets the name of the variable that pkgconf considers |
| | to be the package prefix |
| --relocate=path | relocates a path and exits (mostly for testsuite) |
| --dont-relocate-paths | disables path relocation support |
| cross-compilation personality support: | |
| --personality=triplet-filename | sets the personality to 'triplet' or a file named 'filename' |
| --dump-personality | dumps details concerning selected personality |
| checking specific pkg-config database entries: | |
| --atleast-version | require a specific version of a module |
| --exact-version | require an exact version of a module |
| --max-version | require a maximum version of a module |
| --exists | check whether or not a module exists |
| --uninstalled | check whether or not an uninstalled module will be used |
| --no-uninstalled | never use uninstalled modules when satisfying dependencies |
| --no-provides | do not use 'provides' rules to resolve dependencies |
| --maximum-traverse-depth | maximum allowed depth for dependency graph |
| --static | be more aggressive when computing dependency graph |
| | (for static linking) |
| --pure | optimize a static dependency graph as if it were a normal |
| | dependency graph |
| --env-only | look only for package entries in PKG_CONFIG_PATH |
| --ignore-conflicts | ignore 'conflicts' rules in modules |
| --validate | validate specific .pc files for correctness |
| querying specific pkg-config database fields: | |
| --define-variable=varname=value | define variable 'varname' as 'value' |
| --variable=varname | print specified variable entry to stdout |
| --cflags | print required CFLAGS to stdout |

| --keep-system-cflags | keep -I/usr/include entries in cflags output |
| --keep-system-libs | keep -L/usr/lib64 entries in libs output |
| --path | show the exact filenames for any matching .pc files |

| --internal-cflags | do not filter 'internal' cflags from output |
| filtering output: | |
| --msvc-syntax | print translatable fragments in MSVC syntax |
| --fragment-filter=types | filter output fragments to the specified types |
| | report bugs to <https://todo.sr.ht/~kaniini/pkgconf>. |
