12 > Perform network trace of a single process by using network namespaces.
23
3 This application uses Linux network namespaces to perform network traces of a single application. The traces are saved as pcap files. And can later be analyzed by for instance Wireshark.
4 This application uses Linux network namespaces to perform a network trace of a single application. The trace is saved as a pcap file. And can later be analyzed by for instance Wireshark or tshark.
45
56 The nsntrace application is heavily inspired by the askbubuntu reply [here](https://askubuntu.com/a/499850).
67 And uses the same approach only confined to a single C program.
78
8 What the application does is use the clone syscall to create a new
9 network namespace (CLONE_NEWNET) and from that namespace launch the
10 requested process as well as start a trace using libpcap. This will ensure that all
11 the packets we trace come from the process.

1210
13 The problem we are left with is that the process is isolated in the
14 namespace and cannot reach any other network. We get around that by
15 creating virtual network interfaces. We keep one of them in the
16 root network namespace and but the other one in the newly created one where
17 our tracing takes place. We set the root namespaced one as the default gw
18 of the trace namespaced virtual device.

We set the root namespaced one as the default gateway of the trace namespaced virtual device.

20 And then to make sure we can reach our indented net, we use ip
21 tables and NAT to forward all traffic from the virtual device to our
22 default network interface.

2314
24 This will allow us to capture the packets from a single process while
25 it is communicating with our default network. A limitation is that our
26 ip address will be the NAT one of the virtual device.

28 Another limitation is, that since we are using iptables and since
29 we are tracing raw sockets. This application needs to be run as root.

31 On many systems today the nameserver functionality is handled by an
32 application such as systemd-resolved or dnsmasq and the nameserver
33 address is a loopback address (like 127.0.0.53) where that application
34 listens for incoming DNS queries.

3520
36 This will not work for us in this network namespace environment, since
37 we have our own namespaced loopback device. To work around this one can use the
38 `--use-public-dns` option to override resolv.conf in the namespace. Then nsntrace
39 will use nameservers from Quad9 (9.9.9.9), Cloudflare (1.1.1.1), Google (8.8.8.8) and
40 OpenDNS (208.67.222.222) to perform DNS queries.

413 #
414 # Of course, Automake must honor this variable whenever it calls a
415 # tool from the auxiliary directory. The problem is that $srcdir (and
416 # therefore $ac_aux_dir as well) can be either absolute or relative,
417 # depending on how configure is run. This is pretty annoying, since
418 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
419 # source directory, any form will work fine, but in subdirectories a
420 # relative path needs to be adjusted first.
421 #
422 # $ac_aux_dir/missing
423 # fails when called from a subdirectory if $ac_aux_dir is relative
424 # $top_srcdir/$ac_aux_dir/missing
425 # fails if $ac_aux_dir is absolute,
426 # fails when called from a subdirectory in a VPATH build with
427 # a relative $ac_aux_dir
428 #
429 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
430 # are both prefixed by $srcdir. In an in-source build this is usually
431 # harmless because $srcdir is '.', but things will broke when you
432 # start a VPATH build or use an absolute $srcdir.
433 #
434 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
435 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
436 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
437 # and then we would define $MISSING as
438 # MISSING="\${SHELL} $am_aux_dir/missing"
439 # This will work as long as MISSING is not called from configure, because
440 # unfortunately $(top_srcdir) has no meaning in configure.
441 # However there are other variables, like CC, which are often used in
442 # configure, and could therefore not use this "fixed" $ac_aux_dir.
443 #

1316 \`configure' configures nsntrace 4 to adapt to many kinds of systems.
1317
1318 Usage: $0 [OPTION]... [VAR=VALUE]...
1319
1320 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1321 VAR=VALUE. See below for descriptions of some of the useful variables.
1322
1323 Defaults for the options are specified in brackets.
1324
1325 Configuration:
1326 -h, --help display this help and exit
1327 --help=short display options specific to this package
1328 --help=recursive display the short help of all the included packages
1329 -V, --version display version information and exit
1330 -q, --quiet, --silent do not print \`checking ...' messages
1331 --cache-file=FILE cache test results in FILE [disabled]
1332 -C, --config-cache alias for \`--cache-file=config.cache'
1333 -n, --no-create do not create output files
1334 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1335
1336 Installation directories:
1337 --prefix=PREFIX install architecture-independent files in PREFIX
1338 [$ac_default_prefix]
1339 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1340 [PREFIX]
1341
1342 By default, \`make install' will install all the files in
1343 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1344 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1345 for instance \`--prefix=\$HOME'.
1346
1347 For better control, use the options below.
1348
1349 Fine tuning of the installation directories:
1350 --bindir=DIR user executables [EPREFIX/bin]
1351 --sbindir=DIR system admin executables [EPREFIX/sbin]
1352 --libexecdir=DIR program executables [EPREFIX/libexec]
1353 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1354 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1355 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1356 --runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run]
1357 --libdir=DIR object code libraries [EPREFIX/lib]
1358 --includedir=DIR C header files [PREFIX/include]
1359 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1360 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1361 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1362 --infodir=DIR info documentation [DATAROOTDIR/info]

1387 Optional Features:
1388 --disable-option-checking ignore unrecognized --enable/--with options
1389 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1390 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1391 --enable-silent-rules less verbose build output (undo: "make V=1")
1392 --disable-silent-rules verbose build output (undo: "make V=0")
1393 --enable-dependency-tracking
1394 do not reject slow dependency extractors
1395 --disable-dependency-tracking
1396 speeds up one-time build
1397 --disable-manpages disable manpages

1399 Some influential environment variables:
1400 CC C compiler command
1401 CFLAGS C compiler flags
1402 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1403 nonstandard directory <lib dir>
1404 LIBS libraries to pass to the linker, e.g. -l<library>
1405 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1406 you have headers in a nonstandard directory <include dir>
1407 PKG_CONFIG path to pkg-config utility
1408 PKG_CONFIG_PATH
1409 directories to add to pkg-config's search path
1410 PKG_CONFIG_LIBDIR
1411 path overriding pkg-config's built-in search path
1412 LIBNL_CFLAGS
1413 C compiler flags for LIBNL, overriding pkg-config
1414 LIBNL_LIBS linker flags for LIBNL, overriding pkg-config
1415
1416 Use these variables to override the choices made by `configure' or to help
1417 it to find libraries and programs with nonstandard names/locations.

210 ## supported by the other compilers which use the 'gcc' depmode.

229 ## The problem is that when a header file which appears in a .P file
230 ## is deleted, the dependency causes make to die (because there is
231 ## typically no way to rebuild the header). We avoid this by adding
232 ## dummy dependencies for each header file. Too bad gcc doesn't do
233 ## this for us directly.
234 ## Some versions of gcc put a space before the ':'. On the theory
235 ## that the space means something, we add a space to the output as
236 ## well. hp depmode also adds that space, but also prefixes the VPATH
237 ## to the object. Take care to not repeat it in the output.

239 ## correctly. Breaking it into two sed invocations is a workaround.
