345 #
346 # Of course, Automake must honor this variable whenever it calls a
347 # tool from the auxiliary directory. The problem is that $srcdir (and
348 # therefore $ac_aux_dir as well) can be either absolute or relative,
349 # depending on how configure is run. This is pretty annoying, since
350 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
351 # source directory, any form will work fine, but in subdirectories a
352 # relative path needs to be adjusted first.
353 #
354 # $ac_aux_dir/missing
355 # fails when called from a subdirectory if $ac_aux_dir is relative
356 # $top_srcdir/$ac_aux_dir/missing
357 # fails if $ac_aux_dir is absolute,
358 # fails when called from a subdirectory in a VPATH build with
359 # a relative $ac_aux_dir
360 #
361 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
362 # are both prefixed by $srcdir. In an in-source build this is usually
363 # harmless because $srcdir is '.', but things will broke when you
364 # start a VPATH build or use an absolute $srcdir.
365 #
366 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
367 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
368 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
369 # and then we would define $MISSING as
370 # MISSING="\${SHELL} $am_aux_dir/missing"
371 # This will work as long as MISSING is not called from configure, because
372 # unfortunately $(top_srcdir) has no meaning in configure.
373 # However there are other variables, like CC, which are often used in
374 # configure, and could therefore not use this "fixed" $ac_aux_dir.
375 #
376 # Another solution, used here, is to always expand $ac_aux_dir to an

1334 \`configure' configures openfortivpn 1.17.1 to adapt to many kinds of systems.
1335
1336 Usage: $0 [OPTION]... [VAR=VALUE]...
1337
1338 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1339 VAR=VALUE. See below for descriptions of some of the useful variables.
1340
1341 Defaults for the options are specified in brackets.
1342
1343 Configuration:
1344 -h, --help display this help and exit
1345 --help=short display options specific to this package
1346 --help=recursive display the short help of all the included packages
1347 -V, --version display version information and exit
1348 -q, --quiet, --silent do not print \`checking ...' messages
1349 --cache-file=FILE cache test results in FILE [disabled]
1350 -C, --config-cache alias for \`--cache-file=config.cache'
1351 -n, --no-create do not create output files
1352 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1353
1354 Installation directories:
1355 --prefix=PREFIX install architecture-independent files in PREFIX
1356 [$ac_default_prefix]
1357 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1358 [PREFIX]
1359
1360 By default, \`make install' will install all the files in
1361 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1362 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1363 for instance \`--prefix=\$HOME'.
1364
1365 For better control, use the options below.

1432 --with-ppp set the path to the ppp userspace client on FreeBSD
1433 --with-resolvconf Set the path to the resolvconf executable. Set this
1434 to "DISABLED" to fully disable resolvconf support.
1435 In that case it will not be compiled in and
1436 therefore be unavailable at runtime.
1437 --with-systemdsystemunitdir=DIR
1438 directory for systemd service files

1440 Some influential environment variables:
1441 CC C compiler command
1442 CFLAGS C compiler flags
1443 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1444 nonstandard directory <lib dir>
1445 LIBS libraries to pass to the linker, e.g. -l<library>
1446 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1447 you have headers in a nonstandard directory <include dir>
1448 PKG_CONFIG path to pkg-config utility
1449 PKG_CONFIG_PATH
1450 directories to add to pkg-config's search path
1451 PKG_CONFIG_LIBDIR
1452 path overriding pkg-config's built-in search path
1453 OPENSSL_CFLAGS
1454 C compiler flags for OPENSSL, overriding pkg-config
1455 OPENSSL_LIBS
1456 linker flags for OPENSSL, overriding pkg-config
1457 LIBSYSTEMD_CFLAGS
1458 C compiler flags for LIBSYSTEMD, overriding pkg-config
1459 LIBSYSTEMD_LIBS
1460 linker flags for LIBSYSTEMD, overriding pkg-config
1461
1462 Use these variables to override the choices made by `configure' or to help
1463 it to find libraries and programs with nonstandard names/locations.

209 ## -MM, not -M (despite what the docs say). Also, it might not be
210 ## supported by the other compilers which use the 'gcc' depmode.
211 ## - Using -M directly means running the compiler twice (even worse

228 ## This next piece of magic avoids the "deleted header file" problem.
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.

51 .SH DESCRIPTION
52 .B openfortivpn
53 connects to a VPN by setting up a tunnel to the gateway at
54 \fI<host>\fR:\fI<port>\fR.
55
56 .SH OPTIONS
57 .TP
58 \fB\-\-help\fR
59 Show the help message and exit.
60 .TP
61 \fB\-\-version\fR
62 Show version and exit.
63 .TP
64 \fB\-c \fI<file>\fR, \fB\-\-config=\fI<file>\fR
65 Specify a custom configuration file (default: /usr/local/etc/openfortivpn/config).
66 .TP
67 \fB\-u \fI<user>\fR, \fB\-\-username=\fI<user>\fR
68 VPN account username.
69 .TP
70 \fB\-p \fI<pass>\fR, \fB\-\-password=\fI<pass>\fR
71 VPN account password in plain text.
72 For a secure alternative, use pinentry or let openfortivpn prompt for the password.
73 .TP
74 \fB\-\-pinentry=\fI<name>\fR
75 The pinentry program to use. Allows supplying the password in a secure manner.
76 For example: pinentry-gnome3 on Linux, or pinentry-mac on macOS.
77 .TP
78 \fB\-o \fI<otp>\fR, \fB\-\-otp=\fI<otp>\fR
79 One-Time-Password.
80 .TP
81 \fB\-\-otp\-prompt=\fI<prompt>\fR
82 Search for the OTP password prompt starting with the string \fI<prompt>\fR.
83 .TP
84 \fB\-\-otp\-delay\=\fI<delay>\fR
85 Set the amount of time to wait before sending the One-Time-Password.
86 The delay time must be specified in seconds, where 0 means
87 no wait (this is the default).
88 .TP
89 \fB\-\-no\-ftm\-push\fR
90 Do not use FTM push if the server provides the option.
91 The server may be configured to allow two factor authentication through a
92 push notification to the mobile application. If this option is provided,
93 authentication based on OTP will be used instead.
94 .TP
95 \fB\-\-realm=\fI<realm>\fR
96 Connect to the specified authentication realm. Defaults to empty, which
97 is usually what you want.
98 .TP
99 \fB\-\-ifname=\fI<interface>\fR
100 Bind the connection to the specified network interface.
101 .TP
102 \fB\-\-set\-routes=\fI<bool>\fR, \fB\-\-no-routes\fR
103 Set if openfortivpn should try to configure IP routes through the VPN when
104 tunnel is up. If used multiple times, the last one takes priority.
105
106 \fB\-\-no\-routes\fR is the same as \fB\-\-set-routes=\fI0\fR.
107 .TP
108 \fB\-\-half\-internet\-routes=\fI<bool>\fR
109 Set if openfortivpn should add two 0.0.0.0/1 and 128.0.0.0/1 routes with
110 higher priority instead of replacing the default route.
111 .TP
112 \fB\-\-set\-dns=\fI<bool>\fR, \fB\-\-no\-dns\fR
113 Set if openfortivpn should add DNS name servers in /etc/resolv.conf when
114 tunnel is up. Also a dns\-suffix may be received from the peer and added
115 to /etc/resolv.conf in the turn of adding the name servers.
116 resolvconf is instructed to do the update of the resolv.conf file
117 if it is installed and \-\-use\-resolvconf is activated, otherwise openfortivpn
118 prepends its changes to the existing content of the resolv.conf file.
119 Note that there may be other mechanisms to update /etc/resolv.conf,
120 e.g., \fB\-\-pppd\-use\-peerdns\fR in conjunction with an ip-up-script,
121 which may require that openfortivpn is called with \fB\-\-no\-dns\fR.
122 \fB\-\-no\-dns\fR is the same as \fB\-\-set\-dns=\fI0\fR.
123 .TP
124 \fB\-\-use\-resolvconf=\fI<bool>\fR
125 Set if openfortivpn should use resolvconf to add DNS name servers
126 in /etc/resolv.conf. If it is set to false, the builtin fallback
127 mechanism is used even if resolvconf is available.
128 .TP
129 \fB\-\-ca\-file=\fI<file>\fR
130 Use specified PEM-encoded certificate bundle instead of system-wide store to
131 verify the gateway certificate.
132 .TP
133 \fB\-\-user\-cert=\fI<file>\fR
134 Use specified PEM-encoded certificate if the server requires authentication
135 with a certificate.
136 .TP
137 \fB\-\-user-cert=\fIpkcs11:\fR
138 Use at least the string pkcs11: for using a smartcard. It takes the full
139 or a partial PKCS11-URI (p11tool --list-token-urls)
140
141 --user-cert = pkcs11:
142
143 --user-cert = pkcs11:token=someuser
144
145 --user-cert = pkcs11:model=PKCS%2315%20emulated;manufacturer=piv_II;serial=012345678;token=someuser
146
147 \fBThis feature requires the OpenSSL PKCS engine!
148 .TP
149 \fB\-\-user\-key=\fI<file>\fR
150 Use specified PEM-encoded key if the server requires authentication with
151 a certificate.
152 .TP
153 \fB\-\-pem-passphrase=\fI<pass>\fR
154 Pass phrase for the PEM-encoded key.
155 .TP
156 \fB\-\-use\-syslog\fR
157 Log to syslog instead of terminal.
158 .TP
159 \fB\-\-trusted\-cert=\fI<digest>\fR
160 Trust a given gateway. If classical SSL certificate validation fails, the
161 gateway certificate will be matched against this value. \fI<digest>\fR is the
162 X509 certificate's sha256 sum. The certificate has to be encoded in DER form.
163 This option can be used multiple times to trust several certificates.
164 .TP
165 \fB\-\-insecure\-ssl\fR
166 Do not disable insecure SSL protocols/ciphers.
167 If your server requires a specific cipher, consider using \fB\-\-cipher\-list\fR
168 instead.
169 .TP
170 \fB\-\-cipher\-list=\fI<ciphers>\fR
171 OpenSSL ciphers to use. If default does not work, you can try alternatives
172 such as HIGH:!MD5:!RC4 or as suggested by the Cipher: line in the output of
173 \fBopenssl\fP(1) (e.g. AES256-GCM-SHA384):
174
175 $ openssl s_client -connect \fI<host:port>\fR
176
177 (default: HIGH:!aNULL:!kRSA:!PSK:!SRP:!MD5:!RC4)
178
179 \fBApplies to TLS v1.2 or lower only, not to be used with TLS v1.3 ciphers.\fR
180 .TP
181 \fB\-\-min\-tls=\fI<version>\fR
182 Use minimum TLS version instead of system default. Valid values are 1.0,
183 1.1, 1.2, 1.3.
184 .TP
185 \fB\-\-seclevel\-1\fR
186 If \fB\-\-cipher-list\fR is not specified, add @SECLEVEL=1 to the list of
187 ciphers. This lowers limits on dh key.
188
189 \fBApplies to TLS v1.2 or lower only.\fR
190 .TP
191 \fB\-\-use\-peer\-dns=\fI<bool>\fR, \fB\-\-pppd\-no\-peerdns\fR
192 Whether to ask peer ppp server for DNS server addresses and let pppd
193 rewrite /etc/resolv.conf. There is no mechanism to tell the dns\-suffix
194 to pppd. If the DNS server addresses are requested,
195 also \fB\-\-set\-dns=\fI1\fR may race with the mechanisms in pppd.
196
197 \fB\-\-pppd\-no\-peerdns\fR is the same as \fB\-\-pppd\-use\-peerdns=\fI0\fR.
198 .TP
199 \fB\-\-pppd\-log=\fI<file>\fR
200 Set pppd in debug mode and save its logs into \fI<file>\fR.
201 .TP
202 \fB\-\-pppd\-plugin=\fI<file>\fR
203 Use specified pppd plugin instead of configuring the resolver and routes
204 directly.
205 .TP
206 \fB\-\-pppd\-ipparam=\fI<string>\fR
207 Provides an extra parameter to the ip\-up, ip\-pre\-up and ip\-down scripts. See man
208 .BR pppd(8)
209 for further details
210 .TP
211 \fB\-\-pppd\-ifname=\fI<string>\fR
212 Set the ppp interface name. Only if supported by pppd. Patched versions of pppd
213 implement this option but may not be available on your platform.
214 .TP
215 \fB\-\-pppd\-call=\fI<name>\fR
216 Drop usual arguments from pppd command line and add `call <name>' instead.
217 This can be useful on Debian and Ubuntu, where unprivileged users in
218 group `dip' can invoke `pppd call <name>' to make pppd read and apply
219 options from /etc/ppp/peers/<name> (including privileged ones).
220 .TP
221 \fB\-\-ppp\-system=\fI<string>\fR
222 Only available if compiled for ppp user space client (e.g. on FreeBSD).
223 Connect to the specified system as defined in /etc/ppp/ppp.conf
224 .TP
225 \fB\-\-persistent\=\fI<interval>\fR
226 Run the VPN persistently in an endless loop and try to reconnect forever.
227 The reconnect interval may be specified in seconds, where 0 means
228 no reconnect is done (this is the default).
229 .TP
230 \fB\-v\fR
231 Increase verbosity. Can be used multiple times to be even more verbose.
232 .TP
233 \fB\-q\fR
234 Decrease verbosity. Can be used multiple times to be even less verbose.
235
236 .SH ENVIRONMENT and proxy support
237 .B openfortivpn
238 can be run behind an HTTP proxy that supports the HTTP connect command.
239 It checks if one of the environment variables
240 .B https_proxy HTTPS_PROXY all_proxy ALL_PROXY
241 is set which are supposed to contain a string of the format
242 .br
243 .B http://[host]:[port]
244 .br
245 where
246 .B [host]
247 is the ip or the fully qualified host name of the proxy server
248 .B [port]
249 is the TCP port number where the proxy is listening for
250 incoming connections. If one of these variables is defined,
251 .B openfortivpn
252 tries to first establish a TCP connection to this proxy (plain HTTP, not encrypted),
253 and then makes a request to connect to the VPN host as given on the command line
254 or in the configuration file. The proxy is supposed to forward any subsequent packets
255 transparently to the VPN host, so that the TLS layer of the connection effectively
256 is established between the client and the VPN host, and the proxy just acts as a
257 forwarding instance on the lower level of the TCP connection.
258
259 The following environment variables are set by
260 .B openfortivpn
261 and
262 .BR pppd(8)
263 or its scripts can obtain information this way:
264 .br
265 VPN_GATEWAY the ip of the gateway host
266 .br
267 and for each route three variables are set up, where an integer number
268 is appended to the variable names, denoting the number of the current route:
269 .br
270 VPN_ROUTE_DEST_... the destination network of the route
271 .br
272 VPN_ROUTE_MASK_... the network mask for this route
273 .br
274 VPN_ROUTE_GATEWAY_... the gateway for the current route entry
275
276 If not compiled for pppd the pppd options and features that rely on them are not
277 available. On FreeBSD \fB\-\-ppp\-system\fR is available instead.
278
279 .SH CONFIGURATION
280 Options can be taken from a configuration file. Options passed in the command
281 line will override those from the configuration file, though. The default
282 configuration file is /usr/local/etc/openfortivpn/config, but this can be set
283 using the \fB\-c\fR option.
284 An empty template for the configuration file is installed to
285 /usr/local/share/openfortivpn/config.template
286
287 .TP
288 A configuration file looks like:

82 Options:
83 -q, --quiet quiet
84 -v, --verbose verbose mode
85 --no-tree run without a kernel tree
86 --no-signoff do not check for 'Signed-off-by' line
87 --patch treat FILE as patchfile (default)
88 --emacs emacs compile window format
89 --terse one line per report
90 --showfile emit diffed file position, not input file position
91 -g, --git treat FILE as a single commit or git revision range
92 single git commit with:
93 <rev>
94 <rev>^
95 <rev>~n
96 multiple git commits with:
97 <rev1>..<rev2>
98 <rev1>...<rev2>
99 <rev>-<count>
100 git merges are ignored
101 -f, --file treat FILE as regular source file
102 --subjective, --strict enable more subjective tests
103 --list-types list the possible message types
104 --types TYPE(,TYPE2...) show only these comma separated message types
105 --ignore TYPE(,TYPE2...) ignore various comma separated message types
106 --show-types show the specific message type in the output
107 --max-line-length=n set the maximum line length, (default $max_line_length)
108 if exceeded, warn on patches
109 requires --strict for use with --file
110 --min-conf-desc-length=n set the min description length, if shorter, warn
111 --tab-size=n set the number of spaces for tab (default $tabsize)
112 --root=PATH PATH to the kernel tree root
113 --no-summary suppress the per-file summary
114 --mailback only produce a report in case of warnings/errors
115 --summary-file include the filename in summary
116 --debug KEY=[0|1] turn on/off debugging of KEY, where KEY is one of
117 'values', 'possible', 'type', and 'attr' (default
118 is all off)
119 --test-only=WORD report only warnings/errors containing WORD
120 literally
121 --fix EXPERIMENTAL - may create horrible results
122 If correctable single-line errors exist, create
123 "<inputfile>.EXPERIMENTAL-checkpatch-fixes"
124 with potential errors corrected to the preferred
125 checkpatch style
126 --fix-inplace EXPERIMENTAL - may create horrible results
127 Is the same as --fix, but overwrites the input
128 file. It's your fault if there's no backup or git
129 --ignore-perl-version override checking of perl version. expect
130 runtime errors.
131 --codespell Use the codespell dictionary for spelling/typos
132 (default:/usr/share/codespell/dictionary.txt)
133 --codespellfile Use this codespell dictionary
134 --typedefsfile Read additional types from this file
135 --color[=WHEN] Use colors 'always', 'never', or only when output
136 is a terminal ('auto'). Default is 'auto'.
137 --kconfig-prefix=WORD use WORD as a prefix for Kconfig symbols (default
138 ${CONFIG_})
139 -h, --help, --version display this help and exit
140
141 When FILE is - read standard input.
