There are 4 | just a few small guidelines you need to follow. 5 | 6 | ## Contributor License Agreement 7 | 8 | Contributions to this project must be accompanied by a Contributor License 9 | Agreement. You (or your employer) retain the copyright to your contribution, 10 | this simply gives us permission to use and redistribute your contributions as 11 | part of the project. Head over to to see 12 | your current agreements on file or to sign a new one. 13 | 14 | You generally only need to submit a CLA once, so if you've already submitted one 15 | (even if it was for a different project), you probably don't need to do it 16 | again. 17 | 18 | ## Code reviews 19 | 20 | All submissions, including submissions by project members, require review. We 21 | use GitHub pull requests for this purpose.

Log in to AP 14 | 15 | ### 2. Generate SSH key 16 | 17 | ``` 18 | $ mkdir ~/.ssh 19 | $ dropbearkey -t rsa -f ~/.ssh/id_dropbear -s 2048 20 | ssh-rsa AAAA…== admin@apname 21 | ``` 22 | 23 | ### 3. Add this key to server's `~/.ssh/authorized_keys` 24 | 25 | Try a one-time upload by uploading `ap-uploader.sh` to the AP and running: 26 | ``` 27 | $ ./ap-uploader.sh user@server:path/ 28 | ``` 29 | 30 | ### 4. Set up regular data uploads 31 | 32 | On the AP, run: 33 | ``` 34 | $ nohup sh -c 'while true; do ./ap-uploader.sh user@server:path/;sleep 600;done' & 35 | ``` 36 | 37 | Make sure files are being uploaded to the server every 10 minutes. If it all 38 | looks good then the AP setup is done. At least until it reboots. 39 | 40 | ### 5. On server: Create database 41 | 42 | ``` 43 | $ createdb ubntools 44 | $ psql ubntools -f schema.sql 45 | ``` 46 | 47 | ### 6. Import data 48 | 49 | ``` 50 | $ go build inserter.go 51 | $ ./inserter -dbconnect='dbname=ubntools host=/var/run/postgresql sslmode=disable' /path/to/*.gz 52 | ``` 53 | 54 | ### 7. Query data 55 | 56 | ``` 57 | $ psql ubntools 58 | ubntools=> SELECT * FROM view_neighbors; 59 | ap | channel | bssid | essid | bw | rssi | security | adhoc 60 | ----------+---------+-------------------+------------------------+----+------+----------+------- 61 | apname | 6 | 00:8e:f2:aa:aa:aa | virginmediaxxxxxxx | 20 | 10 | secured | f 62 | […] 63 | ``` 64 | 65 | ### 8. Generate channel utilization graph 66 | 67 | ``` 68 | $ go build mkgraph.go 69 | $ ./mkgraph -dbconnect='dbname=ubntools host=/var/run/postgresql sslmode=disable' | gnuplot 70 | $ mv foo.png /path/to/web/root/or/something/ 71 | ``` 72 | 73 | ## Interesting queries 74 | 75 | There are premade views (do `\d` and then `SELECT * from view_…`), 76 | but you can query more raw data too. 77 | 78 | ### Current clients 79 | ``` 80 | SELECT 81 | essid, 82 | ap, 83 | channel, 84 | data->>'hostname' hostname, 85 | data->>'mac' mac, 86 | data->>'rssi' rssi 87 | FROM sta_table_latest 88 | ORDER BY essid,ap,channel,hostname,mac; 89 | ``` 90 | 91 | ### Active radios 92 | ``` 93 | SELECT 94 | ap, 95 | data->>'name' AS name, 96 | data->>'radio' AS radio, 97 | CASE data->>'is_11ac' WHEN 'true' THEN TRUE ELSE FALSE END as "802.11ac", 98 | data->>'max_txpower' AS power 99 | FROM radio_table_latest 100 | ORDER BY ap, name; 101 | ``` 102 | 103 | ### One client's RSSI over time 104 | ``` 105 | SELECT 106 | ts, 107 | (data->>'rssi')::int rssi 108 | FROM sta_table 109 | WHERE data->>'mac'='11:22:33:44:55:66' 110 | ORDER BY ts; 111 | ``` 112 | 113 | ### rssi of clients over time 114 | ``` 115 | SELECT 116 | ap, 117 | ts, 118 | essid, 119 | channel, 120 | data->>'hostname' hostname, 121 | data->>'mac' mac, 122 | data->>'rssi' rssi 123 | FROM sta_table 124 | ORDER BY data->>'mac',ts; 125 | ``` 126 | 127 | ### Show days when there was at least one DFS event forcing a change of channel 128 | 129 | ``` 130 | # SELECT TO_CHAR(ts,'YYYY-MM-DD') dayy,MIN(channel) channel FROM view_clients_history WHERE ap='ap-longrange' AND ts>'2020-11-01' AND channel>11 GROUP BY dayy ORDER BY dayy;
