.IX Header "DESCRIPTION" |
| 161 |
The vpe config file consists of a series of lines that contain \f(CW\*(C`variable |
| 162 |
= value\*(C'\fR pairs. Empty lines are ignored. Comments start with a \f(CW\*(C`#\*(C'\fR and |
| 163 |
extend to the end of the line. They can be used on their own lines, or |
| 164 |
after any directives. Spaces are allowed before or after the \f(CW\*(C`=\*(C'\fR sign or |
| 165 |
after values, but not within the variable names or values themselves. |
| 166 |
.PP |
| 167 |
The only exception to the above is the \*(L"on\*(R" directive that can prefix any |
| 168 |
\&\f(CW\*(C`name = value\*(C'\fR setting and will only \*(L"execute\*(R" it on the named node, or |
| 169 |
(if the nodename starts with \*(L"!\*(R") on all nodes except the named one. |

All settings are executed \*(L"in order\*(R", that is, later settings of the same |

variable overwrite earlier ones. |
| 179 |
.SH "ANATOMY OF A CONFIG FILE" |
| 180 |
.IX Header "ANATOMY OF A CONFIG FILE" |
| 181 |
Usually, a config file starts with global settings (like the udp port to |
| 182 |
listen on), followed by node-specific sections that begin with a \f(CW\*(C`node = |
| 183 |
nickname\*(C'\fR line. |
| 184 |
.PP |
| 185 |
Every node that is part of the network must have a section that starts |
| 186 |
with \f(CW\*(C`node = nickname\*(C'\fR. The number and order of the nodes is important |
| 187 |
and must be the same on all hosts. It is not uncommon for node sections to |
| 188 |
be completely empty \- if the default values are right. |
| 189 |
.PP |
| 190 |
Node-specific settings can be used at any time. If used before the first |
| 191 |
node section they will set the default values for all following nodes. |
| 192 |
.SH "CONFIG VARIABLES" |
| 193 |
.IX Header "CONFIG VARIABLES" |
| 194 |
.Sh "\s-1GLOBAL\s0 \s-1SETTINGS\s0" |
| 195 |
.IX Subsection "GLOBAL SETTINGS" |
| 196 |
Global settings will affect the behaviour of the running vped daemon, that |
| 197 |
is, they are in some sense node-specific (config files can set different |
| 198 |
values on different nodes using \f(CW\*(C`on\*(C'\fR), but will affect the behaviour of |
| 199 |
the vped daemon and all connections it creates. |
| 200 |
.IP "loglevel = noise|trace|debug|info|notice|warn|error|critical" 4 |
| 201 |
.IX Item "loglevel = noise|trace|debug|info|notice|warn|error|critical" |
| 202 |
Set the logging level. Connection established messages are logged at level |
| 203 |
\&\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. |
| 204 |
.IP "node = nickname" 4 |
| 205 |
.IX Item "node = nickname" |
| 206 |
Not really a config setting but introduces a node section. The nickname is |
| 207 |
used to select the right configuration section and must be passed as an |
| 208 |
argument to the vped daemon. |
| 209 |
.IP "private-key = relative-path-to-key" 4 |
| 210 |
.IX Item "private-key = relative-path-to-key" |
| 211 |
Sets the path (relative to the config directory) to the private key |
| 212 |
(default: \f(CW\*(C`hostkey\*(C'\fR). This is a printf format string so every \f(CW\*(C`%\*(C'\fR must |
| 213 |
be doubled. A single \f(CW%s\fR is replaced by the hostname, so you could |
| 214 |
use paths like \f(CW\*(C`hostkeys/%s\*(C'\fR to fetch the files at the location where |
| 215 |
\&\f(CW\*(C`vpectrl\*(C'\fR puts them. |
| 216 |
.Sp |
| 217 |
Since only the private key file of the current node is used and the |
| 218 |
private key file should be kept secret per-host to avoid spoofings, it is |
| 219 |
not recommended to use this feature. |
| 220 |
.IP "ifpersist = yes|true|on | no|false|off" 4 |
| 221 |
.IX Item "ifpersist = yes|true|on | no|false|off" |
| 222 |
Should the tun/tap device be made persistent, that is, should the device |
| 223 |
stay up even when vped exits? Some versions of the tunnel device have |
| 224 |
problems sending packets when vped is restarted in persistent mode, so |
| 225 |
if the connections can be established but you cannot send packets from |
| 226 |
the local node, try to set this to \f(CW\*(C`off\*(C'\fR and do an ifconfig down on the |
| 227 |
device. |
| 228 |
.IP "ifname = devname" 4 |
| 229 |
.IX Item "ifname = devname" |
| 230 |
Sets the tun interface name to the given name. The default is OS-specific |
| 231 |
and most probably something like \f(CW\*(C`tun0\*(C'\fR. |
| 232 |
.IP "rekey = seconds" 4 |
| 233 |
.IX Item "rekey = seconds" |
| 234 |
Sets the rekeying interval in seconds (default: \f(CW3600\fR). Connections are |
| 235 |
reestablished every \f(CW\*(C`rekey\*(C'\fR seconds. |
| 236 |
.IP "keepalive = seconds" 4 |
| 237 |
.IX Item "keepalive = seconds" |
| 238 |
Sets the keepalive probe interval in seconds (default: \f(CW60\fR). After this |
| 239 |
many seconds of inactivity the daemon will start to send keepalive probe |
| 240 |
every 5 seconds until it receives a reply from the other end. If no reply |
| 241 |
is received within 30 seconds, the peer is considered unreachable and the |
| 242 |
connection is closed. |
| 243 |
.IP "mtu = bytes" 4 |
| 244 |
.IX Item "mtu = bytes" |
| 245 |
Sets the maximum \s-1MTU\s0 that should be used on outgoing packets (basically |
| 246 |
the \s-1MTU\s0 of the outgoing interface) The daemon will automatically calculate |
| 247 |
maximum overhead (e.g. udp header size, encryption blocksize...) and pass |
| 248 |
this information to the \f(CW\*(C`if\-up\*(C'\fR script. |
| 249 |
.Sp |
| 250 |
Recommended values are 1500 (ethernet), 1492 (pppoe), 1472 (pptp). |
| 251 |
.Sp |
| 252 |
This value must be the minimum of the mtu values of all hosts. |
| 253 |
.IP "ip-proto = numerical-ip-protocol" 4 |
| 254 |
.IX Item "ip-proto = numerical-ip-protocol" |
| 255 |
Sets the protocol number to be used for the rawip protocol. This is a |
| 256 |
global option because all hosts must use the same protocol, and since |
| 257 |
there are no port numbers, you cannot easily run more than one vped |
| 258 |
instance using the same protocol, nor can you share the protocol with |
| 259 |
other programs. |
| 260 |
.Sp |
| 261 |
The default is 47 (\s-1GRE\s0), which has a good chance of tunneling through |
| 262 |
firewalls (but note that the rawip protocol is not \s-1GRE\s0 compatible). Other |
| 263 |
common choices are 50 (\s-1IPSEC\s0, \s-1ESP\s0), 51 (\s-1IPSEC\s0, \s-1AH\s0), 4 (\s-1IPIP\s0 tunnels) or 98 |
| 264 |
(\s-1ENCAP\s0, rfc1241) |
| 265 |
.IP "if-up = relative-or-absolute-path" 4 |
| 266 |
.IX Item "if-up = relative-or-absolute-path" |
| 267 |
Sets the path of a script that should be called immediately after the |
| 268 |
network interface is initialized (but not neccessarily up). The following |
| 269 |
environment variables are passed to it (the values are just examples): |
| 270 |
.RS 4 |
| 271 |
.IP "CONFBASE=/etc/vpe" 4 |
| 272 |
.IX Item "CONFBASE=/etc/vpe" |
| 273 |
The configuration base directory. |
| 274 |
.IP "IFNAME=vpn0" 4 |
| 275 |
.IX Item "IFNAME=vpn0" |
| 276 |
The interface to initialize. |
| 277 |
.IP "MTU=1436" 4 |
| 278 |
.IX Item "MTU=1436" |
| 279 |
The \s-1MTU\s0 to set the interface to. You can use lower values (if done |
| 280 |
consistently on all hosts), but this is usually ineffective. |
| 281 |
.IP "MAC=fe:fd:80:00:00:01" 4 |
| 282 |
.IX Item "MAC=fe:fd:80:00:00:01" |
| 283 |
The \s-1MAC\s0 address to set the interface to. The script *must* set the |
| 284 |
interface \s-1MAC\s0 to this value. You will most likely use one of these: |
| 285 |
.Sp |
| 286 |
.Vb 2 |
| 287 |
\& ip link set $IFNAME address $MAC mtu $MTU up # GNU/Linux |
| 288 |
\& ifconfig $IFNAME ether $MAC mtu $MTU up # FreeBSD |
| 289 |

| 304 |
.IP "NODEID=1" 4 |
| 305 |
.IX Item "NODEID=1" |
| 306 |
The numerical node id of the current node. The first node mentioned in the |

.IX Item "http-proxy-host = hostname/ip" |
| 368 |
The \f(CW\*(C`http\-proxy\-*\*(C'\fR family of options are only available if vpe was |
| 369 |
compiled with the \f(CW\*(C`\-\-enable\-http\-proxy\*(C'\fR option and enable tunneling of |
| 370 |
tcp connections through a http proxy server. |
| 371 |
.Sp |
| 372 |
\&\f(CW\*(C`http\-proxy\-host\*(C'\fR and \f(CW\*(C`http\-proxy\-port\*(C'\fR should specify the hostname and |
| 373 |
port number of the proxy server. See \f(CW\*(C`http\-proxy\-loginpw\*(C'\fR if your proxy |
| 374 |
requires authentication. |
| 375 |
.Sp |
| 376 |
Please note that vpe will still try to resolve all hostnames in the |
| 377 |
configuration file, so if you are behind a proxy without access to a dns |
| 378 |
server better use numerical \s-1IP\s0 addresses. |
| 379 |
.Sp |
| 380 |
To make best use of this option disable all protocols except tcp in your |
| 381 |
config file and make sure your routers (or all other hosts) are listening |
| 382 |
on a port that the proxy allows (443, https, is a common choice). |
| 383 |
.Sp |
| 384 |
If you have a router, connecting to it will suffice. Otherwise tcp must be |
| 385 |
enabled on all hosts. |

different settings, even within the same vped instance. Settings that are |

Sets the port number used by the \s-1UDP\s0 protocol (default: \f(CW655\fR, not |
| 414 |
officially assigned by \s-1IANA\s0!). |
| 415 |
.IP "tcp-port = port-number" 4 |

Enable the \s-1RAW\s0 IPv4 transport using the \f(CW\*(C`ip\-proto\*(C'\fR protocol |
| 421 |
(default: \f(CW\*(C`no\*(C'\fR). This is the best choice, since the overhead per packet |
| 422 |
is only 38 bytes, as opposed to \s-1UDP\s0's 58 (or \s-1TCP\s0's 60+). |

Enable the UDPv4 transport using the \f(CW\*(C`udp\-port\*(C'\fR port (default: \f(CW\*(C`yes\*(C'\fR, |
| 426 |
but this will change!). This is a good general choice since \s-1UDP\s0 tunnels |

Enable the TCPv4 transport using the \f(CW\*(C`tcp\-port\*(C'\fR port |

(default: \f(CW\*(C`no\*(C'\fR). Support for this horribly unsuitable protocol is only |
| 435 |
available when vpe was compiled using the \f(CW\*(C`\-\-enable\-tcp\*(C'\fR option. Never |

use this transport unless you really must, it is horribly ineffiecent and |

resource-intensive compared to the other transports. |

Sets the router priority of the given host (default: \f(CW0\fR, disabled). If |
| 441 |
some host tries to connect to another host without a hostname, it asks |
| 442 |
the router host for it's \s-1IP\s0 address. The router host is the one with the |
| 443 |
highest priority that is currently reachable. Make sure all clients always |
| 444 |
connect to the router hosts, otherwise conencting to them is impossible. |

Wether to inherit the \s-1TOS\s0 settings of packets sent to the tunnel when |
| 456 |
sending packets to this node (default: \f(CW\*(C`yes\*(C'\fR). If set to \f(CW\*(C`yes\*(C'\fR then |

outgoing tunnel packets will have the same \s-1TOS\s0 setting as the packets sent |
