酷!學園

我有三台VM ,分別是db1 , db2 , db3 ,  db3除了db1可以ssh 進db3外,其它如ubuntu也不行,請問是什麼原因,我想是認證加密方式所導致,但是不知如何解決

db1
[jjchiou@db1 ~]$ cat .ssh/known_hosts
db3,172.17.128.110 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBKaJayQkBIk223ZehYeTsYonHXhuUFCwoCCOsKaXlpDE6UAHacwuTncGae4EOabY0UkvyWfbe9xi0c68H2ltYcU=

db2
[jjchiou@db2 ~]$ cat .ssh/known_hosts
cat: .ssh/known_hosts: 沒有此一檔案或目錄

Dear man ,

我在用corosync + pacemaker(crmsh) + drbd 做mysql HA

現在crm下設資源後另外一台不能切為master ,蠻奇怪的.

master cleans :

# 1. echo "Now, I will detect your Linux server's services!"
echo -e "The www, ftp, ssh, and mail will be detect! \n"

test80=$(netstat -tuln | grep ":80")
test22=$(netstat -tuln | grep ':22')
test21=$(netstat -tuln | grep ':21')
test25=$(netstat -tuln | grep ':25')

等錯誤請問這是那裡錯了

你好
我想將某一個設定檔特定地方加一行(變成兩行)

<severity>Major</severity>

變成<severity>Major</severity>
<autoaction>/opt/OpenNMS/bin/major.sh<autoaction>

我的script如下

[root@opennms etc]# vi replaceseverity.sh

#/usr/bin/bash
MAJOR="<severity>Major</severity>"
ACTION=`cat /root/major`

echo $ACTION
echo $MAJOR
sed 's/${MAJOR}/${ACTION}/[g]' < /opt/OpenNMS/etc/eventconf.xml

[root@opennms etc]# cat /root/major
<severity>Major</severity>
<autoaction>/opt/OpenNMS/bin/major.sh<autoaction>

[root@opennms etc]# ./replaceseverity.sh
sed: -e expression #1, char 22: unknown option to `s'


請問那裡錯了謝謝

#########################################
Midi 是以電子琴或是吉他等設備所演奏出來的音樂，有別於一般 CD 唱片，Midi 只有音樂而已，但是受歡迎的程度可不亞於一般的唱片喔，小弟也是 Midi 的愛好者之一。

要播放 Midi 檔案，首先要有硬體支援，早期是音效卡透過外接 Midi 裝置達到播放的效果，目前音效卡有內建 Midi 音效處理晶片的只有 Sound Blaster Live，只要讀取官方所提供的 "聲音樣本"，就能夠處理 Midi 合成。這麼說的話，沒有此音效卡就無法播放 Midi 了嗎？請不用擔心，以上所說的是以 "硬體" 直接播放來說明，反之，我們也可以使用 "軟體" 來處理播放 Midi 音效。

在 Linux 上常見的 Midi 音效播放程式為 Timidity，此程式在 Debian Testing/Unstable 皆有附，但有該軟體還不夠，還必須要有 timidity-patches，此套件包含了 timidity 對於各種樂器的補正文件，有了這些 patch 檔案資訊，timidity就能針對 midi 檔案對應的樂器加以模擬並播放出音樂來，很可惜的是 timidity-patches 只有在 stable 上，testing/unstable 並沒有，所以請另行安裝。

在此，小弟建議捨棄 timidity-patches 這個套件，請另外抓取 http://www.stardate.bc.ca/eawpatches/eawpats12_full.rar，然後解壓縮。小弟是解壓縮在 /usr/share/timidity/eawpats/ 之下，然後編輯 /etc/timidity.cfg 並加入以下設定內容：

代碼:

dir /usr/share/timidity/eawpats/
source gravis.cfg
source gsdrums.cfg
source gssfx.cfg
source xgmap2.cfg
 


OK!!!設定好了，準備播放 midi 檔案，由於 Timidity 在執行時需要設定 "輸出輸入"，什麼是輸入呢？可以說是 User Interface Input，由於 Timidity 有許多個 User Interface，比如 gtk+，ncurse，X toolkit 等，可以在 timidity -h 中查閱，小弟便不詳述。輸出呢？可以指定 -Od：dsp device 直接輸出；-Os：ALSA PCM；-Oe：esound server；-Ol：ogg files，方法很多，小弟也不詳述，舉最簡單的例子來說。

1：以 gtk+ 為介面播放
代碼:

timidity -ig -Od your-midi.mid
 


相信喇叭中就會聽到許多好聽的音樂了。(想必您已經設定好音效卡了吧...)

2：以 aRts 為音效輸出
代碼:

artsdsp timidity -ig -Od your-midi.mid
