以 X-Manager 來連 Linux 的圖形介面

在安裝完新的 Linux 機器之後,如果有將 X11 跑起來,並把 run-level 設為 5 的話,應該就可以進到 Linux 的圖形介面了,但當想要遠端連進去使用 Linux 的圖形介面時,該怎麼辦呢?
這裡我們用 X-Manager 來示範連上 Linux 機器的 XDMCP session:

一般我看到的資料是寫著如下的步驟:
· Edit /etc/X11/xdm/Xaccess file
>> uncomment the line “# * #any host can get a login window”.
· Edit /etc/X11/xdm/xdm-config file
>> comment out the line “DisplayManager.RequestPort: 0″.
· Edit /etc/X11/gdm/gdm.conf file
>> set the enable status to True (or 1) in [xdmcp] section.
· Edit /etc/kde/kdm/kdmrc file
>> set the enable status to True (or 1) in [xdmcp] section.
· reboot system.
· The system needs to run in init level 5 (/etc/inittab).
但是,據我測試的結果,其實只要下面的步驟就好了:
· Edit /etc/X11/xdm/Xaccess file
>> uncomment the line “# * #any host can get a login window”.
· Edit /etc/X11/gdm/gdm.conf file
>> set the enable status to true (or 1) in [xdmcp] section.
· Edit /etc/X11/gdm/gdm.conf file
>> uncomment the line "Port=177" in [xdmcp] section.
· reboot system.
機器重啟之後,就可以打開你的 Xmanager3 來連上機器囉:
1. 打開 Xbrowser 直接點選 New 來建一個新的 XDMCP session:
2. 敲入機器的 IP address 之後按 Next :
下面這一頁可以跳過直接按 Next:
4. 填入一個易於辨別的 Session Name 吧,通常 Host name 就好;記得下面的"Execute the session when this new session wizard is finished"接著按 Finish:
5. 在右邊的工作區點選剛剛建立的 KHXAAAS1 按右鍵 Properties :
6. 假如你像我有多個網卡時,在 Local Address 處下拉選擇正確要 Display 的 IP address:
7. 確定之後 open 剛剛建立的 KHXAAAS1:
8. 敲入 User name 跟 Password 之後,呵呵,漂亮的圖形介面就出現囉~

用 dmidecode 來看 LINUX 或 Solaris 的硬體訊息

在 Linux 系統開機狀態下要看目前的 CPU, Memory 狀態,基本的狀態可以由 /proc/cpuinfo 和 /proc/meminfo 得知,但是...你知道你的機器是雙核心?四核心?還是單核的呢?實體有一顆還是兩顆ㄌㄟ?記憶體到底是插了幾個 slot 呢?恐怕就沒辦法從剛剛的兩個檔案中得知了;甚至於萬一機器遠在別縣市客戶的 site,卻又臨時需要查看機器的序號時,這時候有個實用的工具可以輕易的配合來完成這個需求。

那就是 dmidecode 了,他支援了很多的系統喔:
* Linux i386
* Linux x86_64
* Linux ia64
* FreeBSD i386
* FreeBSD x86_64
* NetBSD i386
* OpenBSD i386
* BeOS i386
* Cygwin i386
* Solaris x86 (CVS version)

dmidecode 下載位置:http://download.savannah.gnu.org/releases/dmidecode/

下面就是在我的一台機器 (Dell 2950 Power edge with 2 quad core processors, 8G RAM) 上跑出來的結果,給大家參考參考:(其中 Handle 0x0400~Handle 0x0401 秀出的是兩顆實體 CPU 的訊息,另外 Handle 0x1101~Handle 0x1104 可以看到每個 slot 各插 2G的記憶體,總共是8G的記憶體;這一台機器最大可安插的記憶體量為 32GB 可安裝於 DIMM1~8,可參考 Handle 0x1000 的數據。)

如何在 Firefox3 上面使用不相容的舊套件

今天開心的下載了小火狐 3.0 之後,發現...噫?我熟悉的那狂奔的小火狐的佈景主題ㄌㄟ?
還有一些常用的套件怎麼在相容性檢查中都掛了ㄌㄟ?
Firefox 附加元件的網頁去喵了一下,居然那幾個套件都沒有新版的了,
實在是用的習慣不想換啊....向 Google 大神祈求指示之後,找到了暫時的解決方案,
就是把附加元件相容性檢查給暫時關閉吧~

要怎麼做ㄌㄟ?只要以下三個步驟就行了:
1. 網址輸入「about:config」,接著按下 我會小心的,我保證!的按鈕。
2. 在頁面任一處按滑鼠右鍵選擇〔新增〕->〔真假 (Boolean) 值〕,然後在跳出的視窗中輸入「extensions.checkCompatibility」,將它設為「false」。這樣就可以關閉附加元件的相容檢查了。
3. 第二步驟再做一次,不過這次改成輸入「extensions.checkUpdateSecurity」,也是將它設為「false」。這樣可以關閉附加元件更新時的安全性檢查。
接著重新啟動一下小火狐,呵呵,慣用的套件就又回來囉~

實作 LINUX 改時區,與 NTP server 同步時間

剛裝好的機器,由於 OS 是安裝的是公司精簡版(國外 RD release 的版本),Red Hat Enterprise Linux ES release 4 (Nahant Update 6) 4CD 被精簡成一片 CD,哇勒,一堆工具都被拿掉了...><|||,一開機發現裝好的機器時區居然是 UTC,UTC (Universal Time/Temps Cordonné 世界標準時間),但我們這兒是要用 CST (Central Standard Time 國家標準時間,也有說是中原標準時間)啊,GMT + 8 = UTC + 8 = CST,雖然自己加 8 個小時就好,不過看起來就是給他有點小不舒服,還是改掉好了... 首先我們來看一下目前機器的時間吧:
[root@KHXPROVS1 ~]# date
Fri Jun 13 02:18:59 UTC 2008
果然是 UTC,接下就是要變更時區的步驟囉:
1. 先備份一下 /etc/sysconfig/clock 吧
[root@KHXPROVS1 ~]# cp -p /etc/sysconfig/clock /etc/sysconfig/clock.orig
2. 接著是編輯 /etc/sysconfig/clock ,並將原來的內容換成如下所示:
[root@KHXPROVS1 ~]# vi /etc/sysconfig/clock
ZONE="UTC"
UTC=true
ARC=false
換成:
ZONE="Asia/Taipei"
UTC=false
ARC=false
3. 再來是置換掉目前使用的 /etc/localtime 檔:
cp -p /etc/localtime /etc/localtime.orig
cp -p /usr/share/zoneinfo/Asia/Taipei /etc/localtime
4. 完成囉~

接下來是讓機器跟 NTP server 同步一下系統時間吧:
1. 直接先用 ntpdate 的指令將時間同步一次,這裡使用 NTP server 的 IP 為 10.69.10.22:
[root@KHXPROVS1 ~]# ntpdate 10.69.10.22
13 Jun 11:22:30 ntpdate[20970]: step time server 10.69.10.22 offset 0.977210 sec
2. 用 hwclock -r 來查一下主機板上的系統時間為何:
[root@KHXPROVS1 ~]# date ; hwclock -r
Fri Jun 13 11:25:48 CST 2008
Fri 13 Jun 2008 11:25:48 AM CST -0.015905 seconds
3. 再 hwclock -w 將正確的時間寫回主機板上。
[root@KHXPROVS1 ~]# hwclock -w
再來是設定 NTP service 讓機器自動去跟 NTP server 校時:
1. 編輯 /etc/ntp.conf 檔案,並加入這兩行到檔案的最後:(其中:10.69.10.22是 NTP server 的 IP address)
[root@KHXDHCPS1 ~]# vi /etc/ntp.conf
....
server 10.69.10.22 prefer
restrict 10.69.10.22 mask 255.255.255.255 nomodify notrap noquery
2. 接著讓 ntpd 在每次開機都會自動執行:
[root@KHXPROVS1 ~]# chkconfig --list|grep ntp
ntpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
[root@KHXPROVS1 ~]# chkconfig --level 2345 ntpd on
[root@KHXPROVS1 ~]# chkconfig --list|grep ntp
ntpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@KHXAAAS1 bin]# service ntpd start
Starting ntpd: [ OK ]
3. 接下來可以用這幾個指令查詢一下 NTP sync. 的情況囉:
[root@KHXPROVS1 ~]# ntpstat
synchronised to NTP server (10.69.10.22) at stratum 5
time correct to within 81 ms
polling server every 128 s
[root@KHXPROVS1 ~]# ntptrace
127.0.0.1: stratum 5, offset -0.056545, synch distance 0.081977
KHXOMCS1: stratum 4, offset 0.000000, synch distance 0.010010

對了,附註一下,p.s. 如果有 firewall 的話,iptables 的 rule 中,需要在 INPUT chain 裡加入這一段 (這裡用開放 10.69.10.0/24 這個網域當範例)
/sbin/iptables -A INPUT -p UDP -i eth1 -s 10.69.10.0/24 --dport 123 -j ACCEPT
在 Firewall server 上應該會有像下面的結果:
[root@FW root]# iptables -L -n -v
Chain INPUT (policy DROP 3 packets, 315 bytes)
pkts bytes target prot opt in out source destination
14696 1524K ACCEPT tcp -- eth0 * 0.0.0.0/0 0.0.0.0/0 tcp dpt:22
397K 226M icmpfilter all -- * * 0.0.0.0/0 0.0.0.0/0
0 0 ACCEPT udp -- eth1 * 10.69.10.0/24 0.0.0.0/0 udp dpt:123
395K 226M block1 all -- * * 0.0.0.0/0 0.0.0.0/0

用 PDF-XChange Viewer 來取代 Adobe Acrobat 吧

昨天心血來潮,查看了一下新增移除程式中的 Adobe Acrobat professional,發現這套軟體雖然是編輯 PDF 的功能很強大,但在 v8.1.2 版之後 (目前已經到 v9.0囉),居然要佔掉我的硬碟 1.3G 的空間,真是越來越龐大了...感覺就好像看到 Nero 這套軟體的背影...記得,以前有抓過一套免費的 PDF 編輯軟體:PDF-XChange Viewer,於是就去詢問了一下 Google 大神,發現這到軟體已經到了 v2.035 的版本,而且還是繁體中文綠色免安裝的版本喔。

在下載完 PDF-XChange Viewer v2.035 之後,立刻就將 Adobe Acrobat v8.1.2 這個龐然大物直接從我的硬碟抹去,再將預設的 PDF 開啟軟體指定給 PDF-XChange Viewer。

PDF-XChange Viewer 是一套多功能的 PDF 閱讀器,它功能強大,不過另需安裝 .NETframework才能執行。它具有豐富的標註功能、多頁簽顯示、強大的導出圖像功能、批量搜索、放大與導航功能。支持中文註釋。

※特色※
- 支援多分頁瀏覽,還可以像 IE7 的縮圖索引一樣,將開啟的檔案產生縮圖於一頁,方便點選。
- 程序啟動速度不慢,PDF 檔載入速度很快,就算是大檔案也能很快載入。
- 可以顯示中文檔案。可以輸入中文檔案。
- 可以加文字,加注解,畫箭頭,畫線段,畫多邊形,還可儲存修改後的檔,不會加上浮水印。
- 可以將檔案輸出成圖片。
- 可以自動檢查更新。

這個版本解開壓縮之後不過才 10.2M 比起 Adobe Acrobat 所佔用的硬碟空間實在是小的可以了,甚至於比起
Adobe reader 都要來的小很多,而且用了之後覺得開啟 PDF 文件速度快上很多,而且我很喜歡他的多頁簽顯示功能,對於我這種一次都會開好幾個 PDF 檔來編輯的人,真是太方便了;另外,他的註釋的功能比起 Adobe Acrobat 也好用的多,起碼,字型及大小顏色可以自訂了。不過他似乎沒辦法外帶將一般如 .doc .xls ...之類的文件直接轉換成 PDF 檔,也沒辦法直接列印成 PDF 檔案格式,小遺憾。

有興趣的人可以參考一下:Tracker Software Products Ltd
目前似乎已經有 v2.037.2 中文安裝版了,至於 v2.035 繁中綠色免安裝版本,有興趣的問一下 Google 大神很容易就能找到下載點的。

另外有需要 .NET Framework 的可以到 .NET Framework Version 2.0 Redistributable Package (x86) 去下載吧。

Solaris 10 基本用法之備忘錄

Solaris 10 改用 SMF 服務命令行管理工具來進行 Solaris 10 系統服務的管理,為了怕自己又忘記這些常用 command 的用法,只好貼上來備忘囉...

1. 用 svcs –a 來查看所有服務的狀態:

svcs 命令顯示服務實例的狀態(STATE)、開始時間(STIME)和 FMRI。每個服務的狀態都為下列狀態之一:
-- degraded-服務實例處於啟用狀態,但是以有限的功能運行。
-- disabled-服務實例處於禁用狀態且尚未運行。
-- legacy_run-傳統服務不由 SMF 進行管理,但是可查看服務。此狀態只能由傳統服務使用。
-- maintenance-服務實例遇到錯誤,必須由管理員解決。
-- offline-服務實例處於啟用狀態,但是尚未運行或者無法運行。
-- online-服務實例處於啟用狀態,並且已成功啟動。
-- uninitialized-此狀態是所有服務在配置經過讀取之前的初始狀態。

以下是常見服務的名稱 :
network svc:/milestone/network:default
sshd svc:/network/ssh:default
cron svc:/system/cron:default
automount svc:/system/filesystem/autofs:default
sendmail svc:/network/smtp:sendmail
nfs svc:/network/nfs/server:default
ntpd svc:/network/ntp:default
2. 用 svcs -v -x 檢查當前系統中的服務狀況,並自動診斷出服務出錯的原因。

3. 使用 | (管道符重定向)作更個性化的查找當前所有的服務狀態;例如:
# svcs |grep online 查看當前運行服務
# svcs |grep offline 查看當前停止服務
# svcs |grep ntp 查看 ntpd 服務狀態
4. 用 svcadm 來做 Service 的啟動、停止或重啟:
這裡用 ntpd 來做例子,如果要立刻停止或重啟服務,那麼可以使用 svcadm 的 -t 參數:
# svcadm disable -t network/ntp
(另一種下法是敲入完整的 FMRI 表示的服務名稱:
# svcadm disable -t svc:/network/ntp:default)
停止ntpd服務,等同于 /etc/init.d/ntpd stop
# svcadm enable -t network/ntp
啟動 ntpd 服務,等同于 /etc/init.d/ntpd start
# svcadm restart network/ntp
重啟(停止並啟動) ntpd 服務,等同于 /etc/init.d/ntpd stop; /etc/init.d/ntpd start
# svcadm refresh network/ntp
Relaod ntpd (重新讀取配置文件),等同于 kill -HUP `cat /var/run/ntpd.pid`

最後的小注記:新裝的系統中由於沒有建立系統 DNS 解析配置檔 /etc/resolv.conf 會導致系統dns client 服務啟動失敗,而 dns client 則是許多服務的依賴前置服務,包括 inetd、sshd、sendmail...等幾乎所有的網路服務,就導致整個Solaris 10 系統中的所有網路服務啟動失敗。記得要在安裝完系統之後手動建立與設定 /etc/resolv.conf 和 /etc/defaultrouter 兩個檔案)

Solaris 10 變更 IP address

今天因為之前 IP plan 的一個疏忽,居然讓兩台 server 的 IP 衝到了,只好將其中一台 安裝了 Solaris 10 的 Sun server 改掉,手動將 /etc/hosts 變更之後,並確認過 /etc/hostname.bge0 也都正確後,重起網路,發現 bge0 的 IP address 居然沒改掉,東看西看,終於發現原來 /etc/hosts 居然不像以前用的 Solaris 8 會有 symbolic link 指向 /etc/inet/hosts 這個檔,
在手動將 /etc/inet/hosts 改掉重起網路之後,果然 bge0 的 IP address 已經變更完成。

將下面這些留著當筆記備用吧,果然東西不常用還是容易忘記啊~

要自己使用固定的 IP address 時,要設定檢查下面的幾個檔案:
/etc/nodename (寫 hostname 的地方啦)
/etc/hostname.bge*
/etc/defaultrouter
/etc/hosts (在 Solaris 10 裡用 symbolic link 指到 /etc/inet/hosts)
/etc/networks (在 Solaris 10 裡用 symbolic link 指到 /etc/inet/networks)
/etc/netmasks (在 Solaris 10 裡用 symbolic link 指到 /etc/inet/netmasks)
