[筆記] 在 eeebox (B202) 上裝 FreeBSD 8 然後用上面的 Ralink 無線網卡

1. grab the driver from http://repo.or.cz/w/ralink_drivers/rt2860_fbsd8.git
2. copy the driver to the target machine, extract, make install, and `kldload rt2860`
3. assume you know the wireless channel (ex: 6,11.. etc). if you don't know, run WirelessNetView on a windows box.
4. write ur own /etc/wpa_supplicant.conf:
   network={
   ssid="CCC"
   psk="1111111111"
   }
5. cmd instructions
   # ifconfig wlan0 create wlandev rt28600 wlanmode sta
   # ifconfig wlan0 channel 11 ssid CCC up
   # wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf
   (now switch to another VT)
   # dhclient wlan0

其它自己看:

ychsiao tutorial cacti issue

16:46 * weithenn 怪，現在又變成localhost是up其它的還是Unknown...Orz
16:48 * weithenn cacti沒那麼難吧？為何我搞不定...丁丁化中....
16:56 <@ychsiao> cacti很簡單啊orz
17:00 <@weithenn> ychsiao:但我裝好只要新增的device status都是Unknown
17:01 * weithenn snmpd.conf 有要特地設定什麼嗎？
17:07 <@weithenn> ychsiao:新增的device內是可以看到snmp information的但status都是Unknown
17:14 * weithenn 當我點選至新增的device內同時去看該機器的snmpd.log也都有看到那台cacti在抓我的snmp訊息...
17:40 <@ychsiao> Associated Data Queries有snmp-interface stats ?
17:41 <@ychsiao> host-type generic snmp-enabled host..
17:46 <@weithenn> ychsiao:Associated Data Queries有snmp-interface stats--> Success [12 Items, 6 Rows]
17:48 <@weithenn> ychsiao:Host Template從None改成generic snmp-enabled host，還是一樣 Status Unknown
17:49 * weithenn 補充一下，改完後有跑 poller.php
18:01 <@ychsiao> status unknown是指ping不到之類的吧... 你圖表有出來嗎?
18:06 <@weithenn> ychsiao:出來了，剛打開debug mode，是說找不到rrd檔，然後在執行一次poller.php就可以了，現在status也變成up了
18:06 <@weithenn> ychsiao: m(_._)m
