| 30 | (http://cr.yp.to/djbdns/run-cache-bind-1.html). |
| 31 | |
| 32 | .B dnscache-conf |
| 33 | creates a service directory |
| 34 | .I D |
| 35 | that runs |
| 36 | .BR dnscache (8). |
| 37 | The name |
| 38 | .I D |
| 39 | must start with a slash |
| 40 | and must not contain any special characters. |
| 41 | Normally |
| 42 | .I D |
| 43 | is |
| 44 | .IR /etc/dnscache . |
| 45 | |
| 46 | You can run the service under |
| 47 | .BR svscan (8) |
| 48 | by using the |
| 49 | .BR update-service (8) |
| 50 | program on Debian GNU/Linux |
| 51 | |
| 52 | update-service --add |
| 53 | .I D |
| 54 | |
| 55 | or by creating a symbolic link in the |
| 56 | .BR svscan (8) |
| 57 | directory (normally /service or /etc/service), e.g.: |
| 58 | |
| 59 | ln -s |
| 60 | .I D |
| 61 | /service |
| 62 | |
| 63 | The service will start within five seconds, |
| 64 | and will be restarted upon reboot. |
| 65 | You can use |
| 66 | .BR svc (8) |
| 67 | to control the service. |
| 68 | |
| 69 | .B dnscache-conf |
| 70 | arranges for |
| 71 | .BR dnscache (8) |
| 72 | to chroot to |
| 73 | .IR D /root |
| 74 | and to run under the uid and gid of |
| 75 | .IR acct . |
| 76 | The name |
| 77 | .I acct |
| 78 | must not contain any special characters. |
| 79 | |
| 80 | .B dnscache-conf |
| 81 | arranges for |
| 82 | .BR dnscache (8) |
| 83 | to listen for UDP packets and TCP connections on port 53 of |
| 84 | .IR ip . |
| 85 | |
| 86 | .I ip |
| 87 | is optional; |
| 88 | if it is not supplied, |
| 89 | .B dnscache-conf |
| 90 | arranges for |
| 91 | .BR dnscache (8) |
| 92 | to listen on 127.0.0.1. |
| 93 | |
| 94 | .B dnscache-conf |
| 95 | creates |
| 96 | .IR D /root/ip/127.0.0.1 |
| 97 | so that |
| 98 | .BR dnscache (8) |
| 99 | will accept queries from 127.0.0.1. |
| 100 | |
| 101 | .B dnscache-conf |
| 102 | puts 128 bytes of not-particularly-secret data |
| 103 | into |
| 104 | .IR D /seed |
| 105 | and arranges for |
| 106 | .BR dnscache (8) |
| 107 | to pass |
| 108 | .IR D /seed |
| 109 | to |
| 110 | .BR dns_random_init (3). |
| 111 | If your system has a good source of random data, |
| 112 | you can replace |
| 113 | .IR D /seed |
| 114 | with 128 bytes of data from that source. |
| 115 | |
| 116 | .B dnscache-conf |
| 117 | creates an automatically rotated log directory in |
| 118 | .IR D /log/main. |
| 119 | The logs are owned by |
| 120 | .IR logacct . |
| 121 | The corresponding |
| 122 | .BR multilog (8) |
| 123 | processes run under the uid and gid of |
| 124 | .IR logacct . |
| 125 | The name |
| 126 | .I logacct |
| 127 | must not contain any special characters. |
