.IX Header "DESCRIPTION" |
160 |
The gvpe config file consists of a series of lines that contain \f(CW\*(C`variable |
161 |
= value\*(C'\fR pairs. Empty lines are ignored. Comments start with a \f(CW\*(C`#\*(C'\fR and |
162 |
extend to the end of the line. They can be used on their own lines, or |
163 |
after any directives. Spaces are allowed before or after the \f(CW\*(C`=\*(C'\fR sign or |
164 |
after values, but not within the variable names or values themselves. |
165 |
.PP |
166 |
The only exception to the above is the \*(L"on\*(R" directive that can prefix any |
167 |
\&\f(CW\*(C`name = value\*(C'\fR setting and will only \*(L"execute\*(R" it on the named node, or |
168 |
(if the nodename starts with \*(L"!\*(R") on all nodes except the named one. |

178 |
.SH "ANATOMY OF A CONFIG FILE" |
179 |
.IX Header "ANATOMY OF A CONFIG FILE" |
180 |
Usually, a config file starts with global settings (like the udp port to |
181 |
listen on), followed by node-specific sections that begin with a \f(CW\*(C`node = |
182 |
nickname\*(C'\fR line. |
183 |
.PP |
184 |
Every node that is part of the network must have a section that starts |
185 |
with \f(CW\*(C`node = nickname\*(C'\fR. The number and order of the nodes is important |
186 |
and must be the same on all hosts. It is not uncommon for node sections to |
187 |
be completely empty \- if the default values are right. |
188 |
.PP |
189 |
Node-specific settings can be used at any time. If used before the first |
190 |
node section they will set the default values for all following nodes. |
191 |

192 |
.IX Header "CONFIG VARIABLES" |
193 |
.Sh "\s-1GLOBAL\s0 \s-1SETTINGS\s0" |
194 |
.IX Subsection "GLOBAL SETTINGS" |
195 |
Global settings will affect the behaviour of the running gvpe daemon, that |
196 |
is, they are in some sense node-specific (config files can set different |
197 |
values on different nodes using \f(CW\*(C`on\*(C'\fR), but will affect the behaviour of |
198 |
the gvpe daemon and all connections it creates. |
199 |
.IP "dns-forw-host = hostname/ip" 4 |
200 |
.IX Item "dns-forw-host = hostname/ip" |
201 |
The dns server to forward dns requests to for the \s-1DNS\s0 tunnel protocol |
202 |
(default: \f(CW127.0.0.1\fR, changing it is highly recommended). |
203 |
.IP "dns-forw-port = port-number" 4 |
204 |
.IX Item "dns-forw-port = port-number" |
205 |
The port where the \f(CW\*(C`dns\-forw\-host\*(C'\fR is to be contacted (default: \f(CW53\fR, |
206 |
which is fine in most cases). |
207 |
.IP "if-up = relative-or-absolute-path" 4 |
208 |
.IX Item "if-up = relative-or-absolute-path" |
209 |
Sets the path of a script that should be called immediately after the |
210 |
network interface is initialized (but not neccessarily up). The following |
211 |
environment variables are passed to it (the values are just examples): |
212 |
.RS 4 |
213 |
.IP "CONFBASE=/etc/gvpe" 4 |
214 |
.IX Item "CONFBASE=/etc/gvpe" |
215 |
The configuration base directory. |
216 |
.IP "IFNAME=vpn0" 4 |
217 |
.IX Item "IFNAME=vpn0" |
218 |
The interface to initialize. |
219 |
.IP "MTU=1436" 4 |
220 |
.IX Item "MTU=1436" |
221 |
The \s-1MTU\s0 to set the interface to. You can use lower values (if done |
222 |
consistently on all hosts), but this is usually ineffective. |
223 |
.IP "MAC=fe:fd:80:00:00:01" 4 |
224 |
.IX Item "MAC=fe:fd:80:00:00:01" |
225 |
The \s-1MAC\s0 address to set the interface to. The script *must* set the |
226 |
interface \s-1MAC\s0 to this value. You will most likely use one of these: |
227 |
.Sp |
228 |
.Vb 2 |
229 |
\& ip link set $IFNAME address $MAC mtu $MTU up # GNU/Linux |
230 |
\& ifconfig $IFNAME ether $MAC mtu $MTU up # FreeBSD |
231 |
.Ve |

234 |
.IP "IFTYPE=native # or tincd" 4 |
235 |
.IX Item "IFTYPE=native # or tincd" |
236 |
.PD 0 |
237 |
.IP "IFSUBTYPE=linux # or freebsd, darwin etc.." 4 |
238 |
.IX Item "IFSUBTYPE=linux # or freebsd, darwin etc.." |
239 |
.PD |
240 |
The interface type (\f(CW\*(C`native\*(C'\fR or \f(CW\*(C`tincd\*(C'\fR) and the subtype (usually the os |
241 |
name in lowercase) that this gvpe was configured for. Can be used to select |
242 |
the correct syntax to use for network-related commands. |
243 |
.IP "NODENAME=branch1" 4 |
244 |
.IX Item "NODENAME=branch1" |
245 |
The nickname of the current node, as passed to the gvpe daemon. |
246 |
.IP "NODEID=1" 4 |
247 |
.IX Item "NODEID=1" |
248 |
The numerical node id of the current node. The first node mentioned in the |
249 |
config file gets \s-1ID\s0 1, the second \s-1ID\s0 2 and so on. |
250 |
.RE |

.RS 4 |
252 |
.Sp |
253 |
Here is a simple if-up script: |
254 |
.Sp |
255 |
.Vb 5 |
256 |
\& #!/bin/sh |
257 |
\& ip link set $IFNAME address $MAC mtu $MTU up |
258 |
\& [ $NODENAME = branch1 ] && ip addr add 10.0.0.1 dev $IFNAME |
259 |
\& [ $NODENAME = branch2 ] && ip addr add 10.1.0.1 dev $IFNAME |
260 |
\& ip route add 10.0.0.0/8 dev $IFNAME |
261 |
.Ve |
262 |
.Sp |
263 |
More complicated examples (using routing to reduce arp traffic) can be |
264 |
found in the etc/ subdirectory of the distribution. |
265 |
.RE |
266 |
.IP "ifname = devname" 4 |
267 |
.IX Item "ifname = devname" |
268 |
Sets the tun interface name to the given name. The default is OS-specific |
269 |
and most probably something like \f(CW\*(C`tun0\*(C'\fR. |
270 |
.IP "ifpersist = yes|true|on | no|false|off" 4 |
271 |
.IX Item "ifpersist = yes|true|on | no|false|off" |
272 |
Should the tun/tap device be made persistent, that is, should the device |
273 |
stay up even when gvpe exits? Some versions of the tunnel device have |
274 |
problems sending packets when gvpe is restarted in persistent mode, so |
275 |
if the connections can be established but you cannot send packets from |
276 |
the local node, try to set this to \f(CW\*(C`off\*(C'\fR and do an ifconfig down on the |
277 |
device. |
278 |
.IP "ip-proto = numerical-ip-protocol" 4 |
279 |
.IX Item "ip-proto = numerical-ip-protocol" |
280 |
Sets the protocol number to be used for the rawip protocol. This is a |
281 |
global option because all hosts must use the same protocol, and since |
282 |
there are no port numbers, you cannot easily run more than one gvpe |
283 |
instance using the same protocol, nor can you share the protocol with |
284 |
other programs. |
285 |
.Sp |
286 |
The default is 47 (\s-1GRE\s0), which has a good chance of tunneling through |
287 |
firewalls (but note that the rawip protocol is not \s-1GRE\s0 compatible). Other |
288 |
common choices are 50 (\s-1IPSEC\s0, \s-1ESP\s0), 51 (\s-1IPSEC\s0, \s-1AH\s0), 4 (\s-1IPIP\s0 tunnels) or 98 |
289 |
(\s-1ENCAP\s0, rfc1241) |
290 |
.IP "http-proxy-host = hostname/ip" 4 |
291 |
.IX Item "http-proxy-host = hostname/ip" |
292 |
The \f(CW\*(C`http\-proxy\-*\*(C'\fR family of options are only available if gvpe was |
293 |
compiled with the \f(CW\*(C`\-\-enable\-http\-proxy\*(C'\fR option and enable tunneling of |
294 |
tcp connections through a http proxy server. |
295 |
.Sp |
296 |
\&\f(CW\*(C`http\-proxy\-host\*(C'\fR and \f(CW\*(C`http\-proxy\-port\*(C'\fR should specify the hostname and |
297 |
port number of the proxy server. See \f(CW\*(C`http\-proxy\-loginpw\*(C'\fR if your proxy |
298 |
requires authentication. |
299 |
.Sp |
300 |
Please note that gvpe will still try to resolve all hostnames in the |
301 |
configuration file, so if you are behind a proxy without access to a dns |
302 |
server better use numerical \s-1IP\s0 addresses. |
303 |
.Sp |
304 |
To make best use of this option disable all protocols except tcp in your |
305 |
config file and make sure your routers (or all other hosts) are listening |
306 |
on a port that the proxy allows (443, https, is a common choice). |
307 |
.Sp |
308 |
If you have a router, connecting to it will suffice. Otherwise tcp must be |
309 |
enabled on all hosts. |
310 |
.Sp |
311 |
Example: |
312 |
.Sp |
313 |
.Vb 3 |
314 |
\& http-proxy-host = proxy.example.com |
315 |
\& http-proxy-port = 3128 # 8080 is another common choice |
316 |
\& http-proxy-auth = schmorp:grumbeere |
317 |
.Ve |
318 |
.IP "http-proxy-port = proxy-tcp-port" 4 |
319 |
.IX Item "http-proxy-port = proxy-tcp-port" |
320 |
The port where your proxy server listens. |
321 |
.IP "http-proxy-auth = login:password" 4 |
322 |
.IX Item "http-proxy-auth = login:password" |
323 |
The optional login and password used to authenticate to the proxy server, |
324 |
seperated by a literal colon (\f(CW\*(C`:\*(C'\fR). Only basic authentication is |
325 |
currently supported. |
326 |
.IP "keepalive = seconds" 4 |
327 |
.IX Item "keepalive = seconds" |
328 |
Sets the keepalive probe interval in seconds (default: \f(CW60\fR). After this |
329 |
many seconds of inactivity the daemon will start to send keepalive probe |
330 |
every 5 seconds until it receives a reply from the other end. If no reply |
331 |
is received within 30 seconds, the peer is considered unreachable and the |
332 |
connection is closed. |
333 |
.IP "loglevel = noise|trace|debug|info|notice|warn|error|critical" 4 |
334 |
.IX Item "loglevel = noise|trace|debug|info|notice|warn|error|critical" |
335 |
Set the logging level. Connection established messages are logged at level |
336 |
\&\f(CW\*(C`info\*(C'\fR, notable errors are logged with \f(CW\*(C`error\*(C'\fR. Default is \f(CW\*(C`info\*(C'\fR. |
337 |
.IP "mtu = bytes" 4 |
338 |
.IX Item "mtu = bytes" |
339 |
Sets the maximum \s-1MTU\s0 that should be used on outgoing packets (basically |
340 |
the \s-1MTU\s0 of the outgoing interface) The daemon will automatically calculate |
341 |
maximum overhead (e.g. udp header size, encryption blocksize...) and pass |
342 |
this information to the \f(CW\*(C`if\-up\*(C'\fR script. |
343 |
.Sp |
344 |
Recommended values are 1500 (ethernet), 1492 (pppoe), 1472 (pptp). |
345 |
.Sp |
346 |
This value must be the minimum of the mtu values of all hosts. |
347 |
.IP "node = nickname" 4 |
348 |
.IX Item "node = nickname" |
349 |
Not really a config setting but introduces a node section. The nickname is |
350 |
used to select the right configuration section and must be passed as an |
351 |
argument to the gvpe daemon. |
352 |
.IP "node-up = relative-or-absolute-path" 4 |
353 |
.IX Item "node-up = relative-or-absolute-path" |
354 |
Sets a command (default: no script) that should be called whenever a |
355 |
connection is established (even on rekeying operations). In addition |
356 |
to the variables passed to \f(CW\*(C`if\-up\*(C'\fR scripts, the following environment |
357 |
variables will be set: |
358 |
.RS 4 |
359 |
.IP "DESTNODE=branch2" 4 |
360 |
.IX Item "DESTNODE=branch2" |
361 |
The name of the remote node. |
362 |
.IP "DESTID=2" 4 |
363 |
.IX Item "DESTID=2" |
364 |
The node id of the remote node. |

398 |
.IP "private-key = relative-path-to-key" 4 |
399 |
.IX Item "private-key = relative-path-to-key" |
400 |
Sets the path (relative to the config directory) to the private key |
401 |
(default: \f(CW\*(C`hostkey\*(C'\fR). This is a printf format string so every \f(CW\*(C`%\*(C'\fR must |
402 |
be doubled. A single \f(CW%s\fR is replaced by the hostname, so you could |
403 |
use paths like \f(CW\*(C`hostkeys/%s\*(C'\fR to fetch the files at the location where |
404 |
\&\f(CW\*(C`gvpectrl\*(C'\fR puts them. |

Since only the private key file of the current node is used and the |

488 |
.Sp |
489 |
Enable the UDPv4 transport using the \f(CW\*(C`udp\-port\*(C'\fR port (default: \f(CW\*(C`no\*(C'\fR, |
490 |
unless no other protocol is enabled for a node, in which case this |
491 |
protocol is enabled automatically). |

.IP "inherit-tos = yes|true|on | no|false|off" 4 |
497 |
.IX Item "inherit-tos = yes|true|on | no|false|off" |
498 |
Wether to inherit the \s-1TOS\s0 settings of packets sent to the tunnel when |
499 |
sending packets to this node (default: \f(CW\*(C`yes\*(C'\fR). If set to \f(CW\*(C`yes\*(C'\fR then |
500 |
outgoing tunnel packets will have the same \s-1TOS\s0 setting as the packets sent |
501 |
to the tunnel device, which is usually what you want. |
502 |
.IP "max-retry = positive-number" 4 |
503 |
.IX Item "max-retry = positive-number" |
504 |
The maximum interval in seconds (default: \f(CW3600\fR, one hour) between |
505 |
retries to establish a connection to this node. When a connection cannot |
506 |
be established, gvpe uses exponential backoff capped at this value. It's |
507 |
sometimes useful to set this to a much lower value (e.g. \f(CW120\fR) on |
508 |
connections to routers that usually are stable but sometimes are down, to |
509 |
assure quick reconnections even after longer downtimes. |
510 |
.IP "router-priority = 0 | 1 | positive\-number>=2" 4 |
511 |
.IX Item "router-priority = 0 | 1 | positive-number>=2" |
512 |
Sets the router priority of the given host (default: \f(CW0\fR, disabled). If |
513 |
some host tries to connect to another host without a hostname, it asks |
514 |
the router host for it's \s-1IP\s0 address. The router host is the one with the |
515 |
highest priority larger than \f(CW1\fR that is currently reachable. |
516 |
.Sp |
517 |
Make sure all hosts always connect (\f(CW\*(C`connect = always\*(C'\fR) to the router |
518 |
hosts, otherwise connecting to them might be impossible. |
519 |
.Sp |
520 |
The special value \f(CW1\fR allows other hosts to route through the router |
521 |
host, but they will never route through it by default. The value \f(CW0\fR |
522 |
disables routing. The idea behind this is that some hosts can, if |
523 |
required, bump the \f(CW\*(C`router\-priority\*(C'\fR setting to higher than \f(CW1\fR in their |
524 |
local config to route through specific hosts. If \f(CW\*(C`router\-priority\*(C'\fR is |
525 |
\&\f(CW0\fR, then routing will be refused, so \f(CW1\fR serves as a \*(L"enable, but do |
526 |
not use by default\*(R" switch. |
527 |
.IP "tcp-port = port-number" 4 |
528 |
.IX Item "tcp-port = port-number" |
529 |
Similar to \f(CW\*(C`udp\-port\*(C'\fR (default: \f(CW655\fR), but sets the \s-1TCP\s0 port number. |
530 |
.IP "udp-port = port-number" 4 |
531 |
.IX Item "udp-port = port-number" |
532 |
Sets the port number used by the \s-1UDP\s0 protocol (default: \f(CW655\fR, not |
533 |
officially assigned by \s-1IANA\s0!). |
