38 | .SH "DESCRIPTION" | |
39 | . | |
d6623498 | 40 | This manual page describes the administration interface provided by the |
41 | .BR tripe (8) | |
42 | daemon. | |
43 | .PP | |
44 | The | |
45 | .BR tripectl (8) | |
46 | program can be used either interactively or in scripts to communicate | |
47 | with the server using this interface. Alternatively, simple custom | |
48 | clients can be written in scripting languages such as Perl, Python or | |
49 | Tcl, or more advanced clients such as GUI monitors can be written in C | |
50 | with little difficulty. | |
51 | .PP | |
37941236 | 52 | Administration commands use a textual protocol. Each client command or |
53 | server response consists of a line of ASCII text terminated by a single | |
54 | linefeed character. No command may be longer than 255 characters. | |
d6623498 | 55 | .SS "General structure" |
56 | Each command or response line consists of a sequence of | |
83487ded MW |
57 | whitespace-separated tokens. The number and nature of whitespace |
58 | characters separating two tokens in a client command is not significant; | |
59 | the server always uses a single space character. The first token in a | |
d6623498 | 60 | line is a |
61 | .I keyword | |
62 | identifying the type of command or response contained. Keywords in | |
63 | client commands are not case-sensitive; the server always uses uppercase | |
64 | for its keywords. | |
83487ded MW |
65 | .PP |
66 | In order to allow tokens to contain internal whitespace, a quoting | |
67 | mechanism is provided. Whitespace within matched pairs of quotes \(en | |
68 | either single | |
69 | .RB ` ' ' | |
70 | or double | |
71 | .RB ` """" ' | |
72 | \(en is considered to be internal. Any character (other than newline) | |
73 | may be escaped by preceding it with a backslash | |
74 | .RB ` \e ': | |
75 | in particular, this can be used to include quote characters. It is | |
76 | impossible for a token to contain a newline character. | |
77 | .PP | |
78 | On output, the server will use double quotes when necessary. | |
de014da6 | 79 | .SS "Simple commands" |
80 | For simple client command, the server responds with zero or more | |
d6623498 | 81 | .B INFO |
82 | lines, followed by either an | |
83 | .B OK | |
84 | line or a | |
85 | .B FAIL | |
86 | line. Each | |
87 | .B INFO | |
88 | provides information requested in the command. An | |
89 | .B OK | |
90 | response contains no further data. A | |
91 | .B FAIL | |
3cdc3f3a | 92 | code is followed by a machine-readable explanation of why the command |
d6623498 | 93 | failed. |
94 | .PP | |
de014da6 | 95 | Simple command processing is strictly synchronous: the server reads a |
96 | command, processes it, and responds, before reading the next command. | |
97 | All commands can be run as simple commands. Long-running commands | |
98 | (e.g., | |
99 | .B ADD | |
100 | and | |
101 | .BR PING ) | |
102 | block the client until they finish, but the rest of the server continues | |
bdc44f5b MW |
103 | running. See |
104 | .B "Background commands" | |
105 | to find out how to issue long-running commands without blocking. | |
106 | .SS "Asynchronous broadcasts" | |
107 | There are three types of asynchronous broadcast messages which aren't | |
108 | associated with any particular command. Clients can select which | |
109 | broadcast messages they're interested in using the | |
110 | .B WATCH | |
111 | command. | |
de014da6 | 112 | .PP |
113 | The | |
d6623498 | 114 | .B WARN |
3cdc3f3a | 115 | message contains a machine-readable message warning of an error |
d6623498 | 116 | encountered while processing a command, unexpected or unusual behaviour |
117 | by a peer, or a possible attack by an adversary. Under normal | |
de014da6 | 118 | conditions, the server shouldn't emit any warnings. |
119 | .PP | |
120 | The | |
d6623498 | 121 | .B TRACE |
3cdc3f3a | 122 | message contains a human-readable tracing message containing diagnostic |
d6623498 | 123 | information. Trace messages are controlled using the |
124 | .B \-T | |
125 | command-line option to the server, or the | |
126 | .B TRACE | |
127 | administration command (see below). Support for tracing can be disabled | |
128 | when the package is being configured, and may not be available in your | |
de014da6 | 129 | version. |
130 | .PP | |
131 | Finally, the | |
3cdc3f3a | 132 | .B NOTE |
133 | message is a machine-readable notification about some routine but | |
134 | interesting event such as creation or destruction of peers. | |
de014da6 | 135 | .SS "Background commands" |
136 | Some commands (e.g., | |
137 | .B ADD | |
138 | and | |
139 | .BR PING ) | |
140 | take a long time to complete. To prevent these long-running commands | |
141 | from tying up a server connection, they can be run in the background. | |
142 | Not all commands can be run like this: the ones that can provide a | |
143 | .B \-background | |
144 | option, which must be supplied with a | |
145 | .IR tag . | |
146 | .PP | |
147 | A command may fail before it starts running in the background. In this | |
148 | case, the server emits a | |
149 | .B FAIL | |
150 | response, as usual. To indicate that a command has started running in | |
151 | the background, the server emits a response of the form | |
152 | .BI "BGDETACH " tag \fR, | |
153 | where | |
154 | .I tag | |
155 | is the value passed to the | |
156 | .B \-background | |
157 | option. From this point on, the server is ready to process more | |
158 | commands and reply to them. | |
159 | .PP | |
160 | Responses to background commands are indicated by a line beginning with | |
e04c2d50 | 161 | one of the tokens |
de014da6 | 162 | .BR BGOK , |
163 | .BR BGFAIL , | |
164 | or | |
165 | .BR BGINFO , | |
e04c2d50 | 166 | followed by the command tag. These correspond to the |
de014da6 | 167 | .BR OK , |
168 | .BR FAIL , | |
169 | and | |
170 | .B INFO | |
171 | responses for simple commands: | |
172 | .B BGINFO | |
173 | indicates information from a background command which has not completed | |
174 | yet; and | |
175 | .B BGOK | |
176 | and | |
177 | .B BGFAIL | |
178 | indicates that a background command succeeded or failed, respectively. | |
179 | .PP | |
180 | A background command will never issue an | |
181 | .B OK | |
060ca767 | 182 | or |
9df937a3 | 183 | .B INFO |
060ca767 | 184 | response: it will always detach and then issue any |
185 | .B BGINFO | |
186 | lines followed by | |
de014da6 | 187 | .B BGOK |
188 | response. | |

189 | .SS "Client-provided services" |
190 | .\"* 25 Service-related messages | |
191 | An administration client can provide services to other clients. | |
192 | Services are given names and versions. A client can attempt to | |
193 | .I claim | |
194 | a particular service by issuing the | |
195 | .B SVCCLAIM | |
196 | command. This may fail, for example, if some other client already | |
197 | provides the same or later version of the service. | |
198 | .PP | |
199 | Other clients can issue | |
200 | .I "service commands" | |
201 | using the | |
202 | .B "SVCSUBMIT" | |
203 | command; the service provider is expected to handle these commands and | |
204 | reply to them. | |
205 | .PP | |
206 | There are three important asynchronous messages which will be sent to | |
207 | service providers. | |
208 | .SP | |
209 | .BI "SVCCANCEL " jobid | |
210 | The named job has been cancelled, either because the issuing client has | |
211 | disconnected or explicitly cancelled the job using the | |
212 | .B BGCANCEL | |
213 | command. | |
214 | .SP | |
215 | .BI "SVCCLAIM " service " " version | |
216 | Another client has claimed a later version of the named | |
9df937a3 MW |
217 | .IR service . |
218 | The recipient is no longer the provider of this service. | |
bdc44f5b MW |
219 | .SP |
220 | .BI "SVCJOB " jobid " " service " " command " " args \fR... | |
221 | Announces the arrival of a new job. The | |
222 | .I jobid | |
223 | is a simple token consisting of alphanumeric characters which | |
224 | .B tripe | |
225 | uses to identify this job. | |
226 | .PP | |
227 | The service provider can reply to the job using the commands | |
228 | .BR SVCINFO , | |
229 | .B SVCOK | |
230 | and | |
231 | .BR SVCFAIL . | |
232 | The first of these sends an | |
233 | .B INFO | |
234 | response and leaves the job active; the other two send an | |
235 | .B OK | |
236 | or | |
237 | .B FAIL | |
238 | response respectively, and mark the job as being complete. | |
239 | .PP | |
240 | (Since | |
241 | .B SVCSUBMIT | |
242 | is a potentially long-running command, it can be run in the background. | |
243 | This detail is hidden from service providers: | |
244 | .B tripe | |
245 | will issue the corresponding | |
246 | .BR BG ... | |
247 | responses when appropriate.) | |
3cdc3f3a | 248 | .SS "Network addresses" |
83487ded | 249 | A network address is a sequence of tokens. The first is a token |
3cdc3f3a | 250 | identifying the network address family. The length of an address and |
83487ded | 251 | the meanings of the subsequent tokens depend on the address family. |
3cdc3f3a | 252 | Address family tokens are not case-sensitive on input; on output, they |
253 | are always in upper-case. | |
254 | .PP | |
255 | At present, only one address family is understood. | |
256 | .TP | |
165efde7 | 257 | .BI "INET " address " \fR[" port \fR] |
3cdc3f3a | 258 | An Internet socket, naming an IPv4 address and UDP port. On output, the |
259 | address is always in numeric dotted-quad form, and the port is given as | |
260 | a plain number. On input, DNS hostnames and symbolic port names are | |
165efde7 MW |
261 | permitted; if omitted, the default port 4070 is used. Name resolution |
262 | does not block the main server, but will block the requesting client, | |
263 | unless the command is run in the background. | |
3cdc3f3a | 264 | .PP |
78dcf842 | 265 | If, on input, no recognized address family token is found, the following |
83487ded | 266 | tokens are assumed to represent an |
3cdc3f3a | 267 | .B INET |
2acd7cd6 MW |
268 | address. Addresses output by the server always have an address family |
269 | token. | |
060ca767 | 270 | .SS "Key-value output" |
271 | Some commands (e.g., | |
272 | .B STATS | |
273 | and | |
274 | .BR SERVINFO ) | |
275 | produce output in the form of | |
276 | .IB key = value | |
83487ded | 277 | pairs, one per token. Neither the |
060ca767 | 278 | .I key |
279 | nor the | |
280 | .I value | |
281 | contain spaces. | |
282 | .SS "Trace lists" | |
283 | Commands which enable or disable kinds of output (e.g., | |
284 | .B TRACE | |
285 | and | |
286 | .BR WATCH ) | |
287 | work in similar ways. They take a single optional argument, which | |
288 | consists of a string of letters selecting message types, optionally | |
289 | interspersed with | |
290 | .RB ` + ' | |
291 | to enable, or | |
292 | .RB ` \- ' | |
293 | to disable, the subsequently listed types. | |
294 | .PP | |
295 | If the argument is omitted, the available message types are displayed, | |
296 | one to an | |
297 | .B INFO | |
298 | line, in a fixed-column format. Column zero contains the key letter for | |
299 | selecting that message type; column one contains either a space or a | |
e04c2d50 | 300 | .RB ` + ' |
060ca767 | 301 | sign, if the message type is disabled or enabled respectively; and a |
302 | textual description of the message type begins at column 3 and continues | |
303 | to the end of the line. | |
304 | .PP | |
305 | Lowercase key letters control individual message types. Uppercase key | |
306 | letters control collections of message types. | |

9986f0b5 | 314 | .BI "ADD \fR[" options "\fR] " peer " " address "\fR..." |
3cdc3f3a | 315 | Adds a new peer. The peer is given the name |
316 | .IR peer ; | |
317 | the peer's public key is assumed to be in the file | |
318 | .B keyring.pub | |
319 | (or whatever alternative file was specified in the | |
320 | .B \-K | |
321 | option on the command line). The | |
322 | .I address | |
323 | is the network address (see above for the format) at which the peer can | |
78dcf842 | 324 | be contacted. The following options are recognized. |

335 | .TP | |
0ba8de86 | 336 | .BI "\-keepalive " time |
337 | Send a no-op packet if we've not sent a packet to the peer in the last | |
338 | .I time | |
339 | interval. This is useful for persuading port-translating firewalls to | |
340 | believe that the `connection' is still active. The | |
341 | .I time | |
342 | is expressed as a nonnegative integer followed optionally by | |
343 | .BR d , | |
344 | .BR h , | |
345 | .BR m , | |
346 | or | |

357 | .B "\-mobile" |
358 | The peer is a mobile device, and is likely to change address rapidly. | |
359 | If a packet arrives from an unknown address, the server's usual response | |
360 | is to log a warning and discard it. If the server knows of any mobile | |
361 | peers, however, it will attempt to decrypt the packet using their keys, | |
362 | and if one succeeds, the server will update its idea of the peer's | |

1381 | An unknown key-exchange message arrived. | |
1382 | .SS "PEER warnings" | |
1383 | These are largely concerned with management of peers and the low-level | |
83487ded | 1384 | details of the network protocol. The second token is usually the name of |
e04c2d50 | 1385 | a peer, or |
3cdc3f3a | 1386 | .RB ` \- ' |
1387 | if none is relevant. | |
13a55605 | 1388 | .SP |
3cdc3f3a | 1389 | .BI "PEER " peer " bad-packet no-type" |
1390 | An empty packet arrived. This is very strange. | |
13a55605 | 1391 | .SP |
3cdc3f3a | 1392 | .BI "PEER " peer " bad-packet unknown-category 0x" nn |
1393 | The message category | |
1394 | .I nn | |
1395 | (in hex) isn't understood. Probably a strange random packet from | |
1396 | somewhere; could be an unlikely bug. | |
13a55605 | 1397 | .SP |
3cdc3f3a | 1398 | .BI "PEER " peer " bad-packet unknown-type 0x" nn |
1399 | The message type | |
1400 | .I nn | |
1401 | (in hex) isn't understood. Probably a strange random packet from | |
1402 | somewhere; could be an unlikely bug. | |
13a55605 | 1403 | .SP |
0ba8de86 | 1404 | .BI "PEER " peer " corrupt-encrypted-ping" |
1405 | The peer sent a ping response which matches an outstanding ping, but its | |
1406 | payload is wrong. There's definitely a bug somewhere. | |
13a55605 | 1407 | .SP |
0ba8de86 | 1408 | .BI "PEER " peer " corrupt-transport-ping" |
1409 | The peer (apparently) sent a ping response which matches an outstanding | |
1410 | ping, but its payload is wrong. Either there's a bug, or the bad guys | |
1411 | are playing tricks on you. | |
13a55605 | 1412 | .SP |
3cdc3f3a | 1413 | .BI "PEER " peer " decrypt-failed" |
1414 | An encrypted IP packet failed to decrypt. It may have been mangled in | |
1415 | transit, or may be a very old packet from an expired previous session | |
1416 | key. There is usually a considerable overlap in the validity periods of | |
1417 | successive session keys, so this shouldn't occur unless the key exchange | |
1418 | takes ages or fails. | |
13a55605 | 1419 | .SP |
0ba8de86 | 1420 | .BI "PEER " peer " malformed-encrypted-ping" |
1421 | The peer sent a ping response which is hopelessly invalid. There's | |
1422 | definitely a bug somewhere. | |
13a55605 | 1423 | .SP |
0ba8de86 | 1424 | .BI "PEER " peer " malformed-transport-ping" |
1425 | The peer (apparently) sent a ping response which is hopelessly invalid. | |
1426 | Either there's a bug, or the bad guys are playing tricks on you. | |
13a55605 | 1427 | .SP |
3cdc3f3a | 1428 | .BI "PEER " peer " packet-build-failed" |
1429 | There wasn't enough space in our buffer to put the packet we wanted to | |
1430 | send. Shouldn't happen. | |
13a55605 | 1431 | .SP |
f43df819 | 1432 | .BI "PEER \- socket-read-error " ecode " " message |
3cdc3f3a | 1433 | An error occurred trying to read an incoming packet. |
13a55605 | 1434 | .SP |
f43df819 | 1435 | .BI "PEER " peer " socket-write-error " ecode " " message |
3cdc3f3a | 1436 | An error occurred attempting to send a network packet. We lost that |
1437 | one. | |
13a55605 | 1438 | .SP |
0ba8de86 | 1439 | .BI "PEER " peer " unexpected-encrypted-ping 0x" id |
1440 | The peer sent an encrypted ping response whose id doesn't match any | |
1441 | outstanding ping. Maybe it was delayed for longer than the server was | |
1442 | willing to wait, or maybe the peer has gone mad. | |
13a55605 | 1443 | .SP |
0ba8de86 | 1444 | .BI "PEER \- unexpected-source " address\fR... |
1445 | A packet arrived from | |
1446 | .I address | |
1447 | (a network address \(en see above), but no peer is known at that | |
1448 | address. This may indicate a misconfiguration, or simply be a result of | |
1449 | one end of a connection being set up before the other. | |
13a55605 | 1450 | .SP |
0ba8de86 | 1451 | .BI "PEER " peer " unexpected-transport-ping 0x" id |
1452 | The peer (apparently) sent a transport ping response whose id doesn't | |
1453 | match any outstanding ping. Maybe it was delayed for longer than the | |
1454 | server was willing to wait, or maybe the peer has gone mad; or maybe | |
1455 | there are bad people trying to confuse you. | |
3cdc3f3a | 1456 | .SS "SERVER warnings" |
1457 | These indicate problems concerning the server process as a whole. | |
13a55605 | 1458 | .SP |
3cdc3f3a | 1459 | .BI "SERVER ignore signal " name |
1460 | A signal arrived, but the server ignored it. Currently this happens for | |
1461 | .B SIGHUP | |
1462 | because that's a popular way of telling daemons to re-read their | |
1463 | configuration files. Since | |
1464 | .B tripe | |
1465 | re-reads its keyrings automatically and has no other configuration | |
1466 | files, it's not relevant, but it seemed better to ignore the signal than | |
1467 | let the server die. | |
13a55605 | 1468 | .SP |
3cdc3f3a | 1469 | .BI "SERVER quit signal " \fR[\fInn\fR|\fIname\fR] |
1470 | A signal arrived and | |
1471 | .B tripe | |
1472 | is going to quit. | |
13a55605 | 1473 | .SP |
3cdc3f3a | 1474 | .BI "SERVER quit admin-request" |
1475 | A client of the administration interface issued a | |

1479 | .BI "SERVER quit foreground-eof" |
1480 | The server is running in foreground mode (the | |
1481 | .B \-F | |
1482 | option), and encountered end-of-file on standard input. | |
1483 | .SP | |
f43df819 | 1484 | .BI "SERVER select-error " ecode " " message |
3cdc3f3a | 1485 | An error occurred in the server's main event loop. This is bad: if it |
1486 | happens too many times, the server will abort. | |
1487 | .SS "SYMM warnings" | |
1488 | These are concerned with the symmetric encryption and decryption | |
1489 | process. | |
13a55605 | 1490 | .SP |
3cdc3f3a | 1491 | .BI "SYMM replay old-sequence" |
1492 | A packet was received with an old sequence number. It may just have | |
1493 | been delayed or duplicated, or it may have been an attempt at a replay | |
1494 | attack. | |
13a55605 | 1495 | .SP |
3cdc3f3a | 1496 | .BI "SYMM replay duplicated-sequence" |
1497 | A packet was received with a sequence number we've definitely seen | |
1498 | before. It may be an accidental duplication because the 'net is like | |
1499 | that, or a deliberate attempt at a replay. | |
1500 | .SS "TUN warnings" | |
1501 | These concern the workings of the system-specific tunnel driver. The | |
83487ded | 1502 | second token is the name of the tunnel interface in question, or |
3cdc3f3a | 1503 | .RB ` \- ' |
1504 | if none. | |
13a55605 | 1505 | .SP |
3cdc3f3a | 1506 | .BI "TUN \- bsd no-tunnel-devices" |
1507 | The driver couldn't find an available tunnel device. Maybe if you | |
e04c2d50 | 1508 | create some more |

1524 | Writing from the tunnel device failed. | |
1525 | .SP | |
42da2a58 | 1526 | .BI "TUN " ifname " slip bad-escape" |
1527 | The SLIP driver encountered a escaped byte it wasn't expecting to see. | |
1528 | The erroneous packet will be ignored. | |
13a55605 | 1529 | .SP |
b9066fbb | 1530 | .BI "TUN " ifname " slip eof" |
1531 | The SLIP driver encountered end-of-file on its input descriptor. | |
1532 | Pending data is discarded, and no attempt is made to read any more data | |
1533 | from that interface ever. | |
13a55605 | 1534 | .SP |
b9066fbb | 1535 | .BI "TUN " ifname " slip escape-end" |
1536 | The SLIP driver encountered an escaped `end' marker. This probably | |
1537 | means that someone's been sending it junk. The erroneous packet is | |
1538 | discarded, and we hope that we've rediscovered synchronization. | |
13a55605 | 1539 | .SP |
f43df819 | 1540 | .BI "TUN \- slip fork-error " ecode " " message |
42da2a58 | 1541 | The SLIP driver encountered an error forking a child process while |

13a55605 | 1543 | .SP |
42da2a58 | 1544 | .BI "TUN \- slip no-slip-interfaces" |
1545 | The driver ran out of static SLIP interfaces. Either preallocate more, | |
1546 | or use dynamic SLIP interface allocation. | |
13a55605 | 1547 | .SP |
b9066fbb | 1548 | .BI "TUN " ifname " slip overflow" |
1549 | The SLIP driver gave up reading a packet because it got too large. | |

f43df819 | 1555 | .BI "TUN \- slip read-ifname-failed " ecode " " message |
42da2a58 | 1556 | The SLIP driver encountered an error reading the name of a dynamically |
