5 | [<servername> - <clientaddr>] | |
6 | [<clientaddr>] | |
7 | [<servername>] usually [SERVER] | |
8 | [DEFAULT] | |
9 | ||
10 | Keys are looked up in that order. <servername> must not | |
11 | be a valid IPv4 or IPv6 address. | |
12 | ||
13 | Exceptional settings: | |
14 | ||
15 | server | |
16 | ||
17 | Specifies <servername>. | |
18 | Is looked up in [SERVER] and [DEFAULT] only. | |
19 | If not specified there, it is SERVER. | |
20 | ||
21 | password | |
22 | ||
23 | Looked up in the usual way, but used by client to | |
24 | determine its own <clientaddr>s. | |
25 | ||
26 | The client will create a local interface, and try to communicate | |
27 | with the server, for Each (<servername>,<clientaddr>) pair for | |
28 | which the config search yields a password. | |
29 | ||
30 | On the server: clients with no password are ignored. | |
31 | ||
32 | Capped settings: | |
33 | ||
34 | Values in <servername> are a cap (maximum) on those from the | |
35 | other sections (including DEFAULT): | |
36 | ||
37 | max_batch_down | |
38 | Size limit for response payloads (server only) [65536 bytes] | |
39 | ||
40 | max_queue_time | |
41 | Discard downwards packets after this long (server only) [10 s] | |
42 | ||
43 | http_timeout | |
44 | (On server) return with empty payload any http request oustanding | |
45 | for this long | |
46 | (On client) give up on any http request outstanding for | |
47 | for this long plus http_timeout_grace | |
48 | Client's effective timeout must be at least server's (checked). | |
49 | [30 s] | |
50 | ||
51 | target_requests_outstanding | |
52 | (On server) whenever number of outstanding requests for | |
53 | a client exceeds this, return oldest with empty payload | |
54 | (On client) try to keep this many requests outstanding. | |
55 | Must match between client and server (checked). [3] | |
56 | ||
57 | Ordinary settings, used by client and server: | |
58 | ||
59 | ipif | |
60 | Command to run to create and communicate with local network | |
61 | interface. Passed to sh -c. Must speak SLIP on stdin/stdout. | |
62 | The following additional interpolations aare substituted: | |
63 | %(local)s %(peer)s %(rnet)s | |
64 | on server <vaddr> <vrelay> <vnetwork> | |
65 | on client <client> <vaddr> <vroutes> | |
66 | ["userv root ipif %(local)s,%(peer)s,%(mtu)s,slip %(rnets)s"] | |
67 | ||
68 | addrs | |
69 | Public IP (v4 or v6) address(es) of the server; | |
70 | space-separated. | |
71 | (On server) mandatory; used for bind. No default. | |
72 | (On client) used only to construct default url. | |
73 | ||
74 | vnetwork | |
75 | Private network range (<prefix>/<length>). Must contain all | |
76 | <client>s. Must contain <vaddr> and <vrelay>, and used | |
77 | to compute their defaults. [172.24.230.192/28] | |
78 | ||
79 | vaddr | |
80 | Address of server's virtual interface. | |
81 | ||
82 | vrelay | |
83 | Virtual point-to-point address used for tunnel routing | |
84 | (does not appear in packets). | |
85 | [first host entry in <vnetwork> other than <vaddr>, | |
86 | so 172.24.230.194] | |
87 | ||
88 | port | |
89 | Public port number of the server. [80] | |
90 | (On server) used for bind. | |
91 | (On client) used only to construct default url. | |
92 | ||
93 | mtu | |
94 | Must match exactly. (checked) [1500 bytes] | |
95 | ||
96 | Ordinary settings, used by client only: | |
97 | ||
98 | http_timeout_grace | |
99 | See http_timeout. [5 s] | |
100 | ||
101 | max_requests_outstanding | |
102 | Client will hold off sending more requests than this to | |
103 | server even if it has data to send. [6] | |
104 | ||
105 | max_batch_up | |
106 | Size limit for request payloads. [4000 bytes] | |
107 | ||
108 | http_retry | |
109 | If a request fails, wait this long before considering it | |
110 | "finished" - to limit rate of futile requests. [5 s] | |
111 | ||
112 | url | |
113 | Public url of server. | |
114 | [http://<first-entry-in-addrs>:<port>/] | |
115 | ||
116 | vroutes | |
117 | Virtual addresses (in CIDR syntax) to be found at the server | |
118 | end, space-separated. Routes to those will be created on | |
119 | the client. [""] |
