test使用帮助

Sun, 12 Aug 2007 02:38:00 GMT

suse:~ # help test
test: test [expr]
    Exits with a status of 0 (true) or 1 (false) depending on
    the evaluation of EXPR. Expressions may be unary or binary. Unary
    expressions are often used to examine the status of a file. There
    are string operators as well, and numeric comparison operators.

    File operators:

        -a FILE        True if file exists.
        -b FILE        True if file is block special.
        -c FILE        True if file is character special.
        -d FILE        True if file is a directory.
        -e FILE        True if file exists.
        -f FILE        True if file exists and is a regular file.
        -g FILE        True if file is set-group-id.
        -h FILE        True if file is a symbolic link.
        -L FILE        True if file is a symbolic link.
        -k FILE        True if file has its `sticky' bit set.
        -p FILE        True if file is a named pipe.
        -r FILE        True if file is readable by you.
        -s FILE        True if file exists and is not empty.
        -S FILE        True if file is a socket.
        -t FD          True if FD is opened on a terminal.
        -u FILE        True if the file is set-user-id.
        -w FILE        True if the file is writable by you.
        -x FILE        True if the file is executable by you.
        -O FILE        True if the file is effectively owned by you.
        -G FILE        True if the file is effectively owned by your group.
        -N FILE        True if the file has been modified since it was last read.

      FILE1 -nt FILE2 True if file1 is newer than file2 (according to
                       modification date).

      FILE1 -ot FILE2 True if file1 is older than file2.

      FILE1 -ef FILE2 True if file1 is a hard link to file2.

    String operators:

        -z STRING      True if string is empty.

        -n STRING
        STRING         True if string is not empty.

        STRING1 = STRING2
                       True if the strings are equal.
        STRING1 != STRING2
                       True if the strings are not equal.
        STRING1 < STRING2
                       True if STRING1 sorts before STRING2 lexicographically.
        STRING1 > STRING2
                       True if STRING1 sorts after STRING2 lexicographically.

    Other operators:

        -o OPTION      True if the shell option OPTION is enabled.
        ! EXPR         True if expr is false.
        EXPR1 -a EXPR2 True if both expr1 AND expr2 are true.
        EXPR1 -o EXPR2 True if either expr1 OR expr2 is true.

        arg1 OP arg2   Arithmetic tests. OP is one of -eq, -ne,
                       -lt, -le, -gt, or -ge.

    Arithmetic binary operators return true if ARG1 is equal, not-equal,
    less-than, less-than-or-equal, greater-than, or greater-than-or-equal
    than ARG2.

SuSE安装Oracle 9i后无法自动启动数据库

Sun, 15 Jul 2007 10:26:00 GMT

在SuSE Linux Enterprise Server 9上安装Oracle9i后，及时使用了安装了orarun-1.8-109.15.i586.rpm包，也无法正常启动�?br>

其中�Q�在Oracle9i中已�l�通过spfile${ORACLE_SID}.ora。因此，��PFILE变量修改为：
PFILE=${ORACLE_HOME}/dbs/spfile${ORACLE_SID}.ora
同时�Q��ؓ了可以在��x��的时候关闭数据库�Q�同时在$ORACLE_HOME/bin/dbshut文�g中对应的位置也需要修改PFILE文�g的定义�?br>
另外�Q�还有一�U�方法，��是生成pfile。用sqlplus�q�接数据库，

create pfile from spfile;
�q�样�Q�就会参�?{ORACLE_HOME}/dbs/spfileora9i.ora生成initora9i.ora�q�个pfile。这样就不用改启动脚本文件了�?br>

pure-ftpd对虚拟用��L��支持

Mon, 10 Apr 2006 16:27:00 GMT

1 �Q�简�?/span>

自从 0.99.2 版本开始， pure-ftpd ��开始支持虚拟用戗��虚拟用��h��式十分类�?/span> /etc/passwd �Q�将用户的相关信息，如口令、姓名�?/span> uid 、目录等�Q�存入文件。但是该文�g只适用�?/span> FTP �?/span>

�q�意味着�Q�可以�ؓ FTP 讄��虚拟用户�Q�而不需要在�pȝ��中添加系�l�用戗��同�Ӟ��可以��些用户单独设�|�配额�?/span> ratio 、带宽等限制。很多虚拟用户可以共享同一个系�l�用��L��属性，因此��些虚拟用户单独创��Z��个系�l�用��P��从而方便管理�?/span>

首先�Q�可以在�pȝ��中添加相应的用户和组�Q�如 ftpuser �?/span> ftpgroup 。如�Q?/span>

groupadd ftpgroup

useradd -g ftpgroup -d /dev/null -s /etc ftpuser

可以使用 ”pure-pw�?/font> 来创��拟用戗��虚拟用��L��信息以每个用户一行的方式存放在相应的文�g中，其格式如下所�C�：

:::::: bandwidth>:::: of connections>:::: local IPs>::: restrictions>

其中�Q�除了帐受��口令�?/span> uid �?/span> gid �?/span> home 目录之外�Q�其它的可以是空倹{�?/span>

2 �Q�创��Z��个用�?/span>

接下来，我们来创��Z��个新的用戗��?/span> pure-pw 的语法规范如下：

pure-pw useradd [-f ] -u [-g ]

-D/-d [-c ]

[-t ] [-T ]

[-n ] [-N ]

[-q ] [-Q ]

[-r [/][,[/]]...]

[-R [/][,[/]]...]

[-i [/][,[/]]...]

[-I [/][,[/]]...]

[-y ]

[-z -] [-m]

假设我们要创�?/span> joe �q�样一个虚拟用��P��则可以��用如下命令：

pure-pw useradd joe -u ftpuser -d /home/ftpusers/joe

其中�Q?/span> -u ��虚拟用�?/span> joe 同系�l�用�?/span> ftpuser 兌��在一赗��?/span> -d 参数�?/span> joe 只能讉K��?/span> home 目录。而如果想让他讉K��整个文�g�pȝ��Q�可以用 -D 选项�?/span>

�q�时�Q�如�?/span> pure-ftpd 启动时加�?/span> -j(--createhome) 选项�Q�则不需要创�?/span> /home/ftpuser/joe 目录。系�l�会在该用户�W�一�ơ登陆时自动创徏�?/span>

-z 选项�q�用用户在一天当中指定的旉��D�连接服务器。如 -z 0900-1800 �Q�则该用户只能在上午 9 点到晚上 6 点之间连接服务器�?/span>

-r 选项�?/span> -R 选项�Q�可以限制用户从指定 IP 和掩码连入服务器

-y �Q�用户同一旉��的�ƈ发连接数�?/span> ’�?/font> 或�?/span> 0 意味着不限�?/span>

-f �Q�默认虚拟用��L��信息会被存放�?/span> /etc/pureftpd.passwd 文�g中，通过该选项可以改变该文件的位置�?/span>

用户的口令会�Ҏ��pȝ��对加密方式的支持情况�Q�选择一个最安全的方式进行加密�?/span>

3 �Q�更改一个用�?/span>

�?/span> pure-pw adduser 唯一不同的是�Q��?/span> pure-pw usermod 不是创徏一个用��P��而是更改已经存在用户的某些属性�?/span>

重置某些属性的语法如下�Q?/span>

pure-pw usermod -n '' �Q�禁用文仉��?/span>

pure-pw usermod -N '' �Q�禁用文件大��配�?/span>

pure-pw usermod -q '' -Q '' �Q�禁�?/span> ratio

pure-pw usermod -t '' �Q�禁用下载带宽限�?/span>

pure-pw usermod -T '' �Q�禁用上传带宽限�?/span>

pure-pw usermod <-i,-I,-r or -R> '' �Q�禁�?/span> IP �q��o

pure-pw usermod -z '' �Q�禁用时间段�U�束

pure-pw usermod -y '' �Q�禁用�ƈ发数限制

4 �Q�删除一个用�?/span>

删除一个用的命令语法是�Q?/span>

pure-pw userdel [-f ] [-m]

�q�时�Q�用��L��信息会被从指定的 passwd 文�g中删除，但是用户�?/span> home 目录会被保留�Q�需要手工删除�?/span>

5 �Q�改变用户口�?/span>

更改一个用户口令的语法是：

pure-pw passwd [-f ] [-m]

6 �Q�显�C�用户信�?/span>

/etc/pureftpd.passwd 文�g中记录的信息不方便用��L��阅读�Q�因�?/span> pure-ftpd 提供了显�C�用户信息的命��o。其语法是：

pure-pw show [-f ]

7 �Q�提交更�?/span>

可以通过上面提到的命令，或者以手工方式�?/span> /etc/pureftpd.passwd 文�g�q�行修改�Q�从而创建、修改和删除一个虚拟用户信息。但是，只有提交�q�些更改�Ӟ�� pure-ftpd 讉K��才能生效�?/span>

提交更改�Q�意味着�pȝ��会根�?/span> /etc/pureftpd.passwd �Q�或者指定的其它文�g�Q�来创徏一�?/span> pure-ftpd 可读的二�q�制格式的文�?/span> /etc/pureftpd.pdb 。通常�Q�通过下面的命令：

pure-pw mkdb

可以通过 /etc/pureftpd.passwd 文�g自动创徏 /etc/pureftpd.pbd 文�g。但是，如果需要指定特定的文�g�Q�可以通过下面的方式来实现�Q?/span>

pure-pw mkdb /etc/accounts/myaccounts.pdb -f /etc/accounts/myaccounts.txt

�q�时�Q�没有必要去重启 pure-ftpd 服务�Q�对虚拟用户�q�行的更改可以更新。同�Ӟ��也可以通过 -m 选项�Q�在�?/span> /etc/pureftpd.passwd 文�g�q�行修改的时候自动进行提交�?/span>

8 �Q�打开对虚拟用��L��支持

使得 pure-ftpd 支持虚拟用户�Q�需要在�~�译的时候加入选项 --with-puredb 。这�Ӟ��可以通过在启动服务是�?/span> �?l�?/font> 参数来设�|�。如�Q?/span>

/usr/local/sbin/pure-ftpd -j -lpuredb:/etc/pureftpd.pdb &

可以在后収ͼ�以自动创��拟用�?/span> home 目录�Q�用 puredb 的方式来支持虚拟用户�?/span>

9 �Q��{换系�l�用�?/span>

可以通过如下命��o�Q�将�pȝ��用户转换��拟用��P��

pure-pwconvert

如果�?/span> root 用户�q�行该命令，�pȝ��用户的口令一�q�被转入虚拟用户配置文�g。如�Q?/span>

pure-pwconvert >> /etc/pureftpd.passwd

10 �Q�环境变�?/span>

默认的情况下�Q�如果指定了环境变量 PURE_PASSWDFILE �Q�则虚拟用户�?/span> passwd 文�g位置��p��变量的值指定。否则，默认�?/span> /etc/pureftpd.passwd 。用��P�� PURE_DBFILE 环境变量用来指定 pdb 文�g的位�|�。默认是 /etc/pureftpd.pdb �?/span>

Linux-NTFS RPMs Documentation

Thu, 06 Apr 2006 06:49:00 GMT

转蝲�Q?a >http://www.linux-ntfs.org/content/view/127/63/�Q?br />
This documentation should help you choosing the right RPM for your kernel and Linux distribution, and assist you in installing (and testing) it.

Which RPM

It is important to install exactly the same version of NTFS kernel module as the kernel you have installed. Below are some simple instructions to help you find the file you need.

A quick way to find the version is to use the . Save the file and run it. Then go to the install section.

				
						

						
						    chmod 
						700
						 whichrpm
    ./whichrpm

				
				

				
The script, above, just automates what we will do next. First we need to decide which release you have. Run this command:

				
						

						
						    cat /etc/redhat-release

				
				

				
and you will probably see one of the following responses:

				
						
						
								

								    Fedora Core release 
						3
						 (Heidelberg)
    Fedora Core release 
						4
						 (Stentz)
    Fedora Core release 
						5
						 (Bordeaux)
    Red Hat Linux release 
						9
						 (Shrike)

Next find out your kernel version:

You should see a response something like one of these:

The version might also have one of the following suffixes:

				
						
						
								

								    smp
    bigmem
    hugemem
    BOOT

Note: If the result ends with smp then you have a multi-processor computer (you probably already knew that).

Next find out what sort of processor you have. This command will ask which kernel rpm was installed for you.

Note: If your version number had a suffix, then use it here, e.g. replace kernel with kernel-smp, or kernel-bigmem.

				
						
						
								

								    rpm -q --queryformat 
						"
						%{ARCH}\n
						"
						 kernel

Most people will have an i686 processor (a recent Pentium computer). Other options are athlon, i586 or i386.

Next download the RPM. Follow the links for

* Fedora 4 (Stentz)
* Fedora 3 (Heidelberg)
* Fedora 2 (Tettnang)
* Fedora 1 (Yarrow)
* RedHat Enterprise 4 (Nahant)
* RedHat Enterprise 3 (Taroon)
* RedHat 9 (Shrike)
* RedHat 8.0 (Psyche)
* RedHat 7.3 (Valhalla)

When you have downloaded the RPM, we will continue with the installation instructions.

Install

You must be root for the rest of the commands. The examples will continue as if you downloaded kernel-ntfs-2.4.18-14.i686.rpm.

Note: Newer NTFS RPMs have names like


    kernel-module-ntfs-2.6.8-1.541-2.1.17-0.fc.1.2.i586.rpm

Next install the rpm:

    rpm -ihv kernel-ntfs-2.4.18-14.i686.rpm

    Preparing...      ############################### [100%]
       1:kernel-ntfs  ############################### [100%]

There should be no errors, just some '#'-charakters.

Note: newer NTFS RPMs will also print a message telling you if install succeeded.

If something goes wrong see the Help Section.

This is the only command we actually needed, but we'll go on and test what we have done.

Next load the kernel module


    /sbin/modprobe ntfs

There should be no output. If there are a lot of error messages see the Help Section.

The next command, dmesg prints the kernel logs. We search them for NTFS using grep.


    dmesg | grep NTFS

    NTFS driver v1.1.22 [Flags: R/O MODULE]

We can now check that the kernel really understands NTFS. The output may vary slightly, but you are looking for the entry ntfs.


    cat /proc/filesystems

    nodev   rootfs
    nodev   bdev
    nodev   proc
    nodev   sockfs
    nodev   tmpfs
    nodev   shm
    nodev   pipefs
            ext3
            ext2
    nodev   ramfs
    nodev   devpts
            ntfs

Mount

Mounting an NTFS Volume is covered in more detail in Section 4 of the Linux-NTFS FAQ (in the Wiki).

First you need to know which device your NTFS Volume is on and you need to create a directory as a mount point.

    /sbin/fdisk -l

The output might look like:

    Disk /dev/hda: 64 heads, 63 sectors, 4465 cylinders
    Units = cylinders of 4032 * 512 bytes

       Device Boot    Start       End    Blocks   Id  System
       /dev/hda1             1      2125   4283968+  07  NTFS/HPFS
       /dev/hda2          2126     19851  35735616   0f  Win95 Ext'd (LBA)
       /dev/hda5   *      2126      4209   4201312+  83  Linux
       /dev/hda6          4210      4465    516064+  82  Linux swap
          

    mkdir /mnt/windows
    mount /dev/hda1 /mnt/windows -t ntfs -r -o umask=0222
    ls -l /mnt/windows

    ...
    -r-xr--r-- 1 root root  9719 Aug 24 1996 ansi.sys
    -r-xr--r-- 1 root root 15252 Aug 24 1996 attrib.exe
    -r-xr--r-- 1 root root 28096 Aug 24 1996 chkdsk.exe
    -r-xr--r-- 1 root root  5175 Aug 24 1996 choice.com
    ...

Hopefully everything is working for you now.

Note: Now, please read the NTFS FAQ (Frequently Asked Questions, in the Wiki), especially if you want to know:

* How to change the owner or permissions of the mounted partition (Section 4.9) * How to have Linux mount the partition automatically at boot time (Section 4.10)

Uninstall

If you wish to remove the NTFS RPM, first list all the RPMs with ntfs in their name. You output might look something like this:

    rpm -qa | grep -i ntfs

��媒体服务器Helix安装

Tue, 04 Apr 2006 06:39:00 GMT

      ��Z��充分教研室服务器的资源，打算在服务器上安装一个流媒体�Ҏ��pȝ��。�ؓ此，选择使用Real公司的Helix产品。只要有合适的License�Q�Helix可以支持�l�大多数的流媒体格式�Q�包括：
RealNetworks:          RealAudio (.rm, .ra), RealVideo (.rm, .rmvb), RealPix (.rp),RealText (.rt), Multi-Rate Container (.mrc)
Macromedia:             Flash (.swf)
Microsoft:                 Windows Media (.asf, .wma, .wmv)
Apple:                      QuickTime (.mov)
Standards-Based:      MPEG-4, MP3
Image Formats:         GIF (.gif), JPEG (.jpg, jpeg), PNG (.png)
Other:                      AU (.au), AIFF (.aif, .ief), WAV (.wav)

      教研室的服务器安装的是Fedora Core 4 x86_64�pȝ��Q�开始只扑ֈ�了Helix Server 9.0.2.794。安装之后，�q�行时提�C�错误：

* Heartbeat Failure 1 (Step 3)

-------------------------------------------------------------------------------
*** Helix Server Heartbeat Failure Report
When: 04-Apr-06 14:09:41
Environment: linux-2.2-libc6-i586-server, , 9.0.2.794

Heartbeat check disabled
* Heartbeat Failure 4 (Step 3)
* Heartbeat Failure 5 (Step 3)
* Heartbeat Failure 6 (Step 3)

在网上找了很多相关的资料�Q�都没解册��个问题。后来考虑可能时系�l�版本的问题�Q�于是下载了Helix Server 11.0.1.1884。在�q�个版本自带的文档中介绍了遇��C��q�问题时�Q�可以在配置文�g�l�尾加入如下3行代码：
�?br />
其中�Q�any指得是服务器的IP地址。但是，按照�q�种方式修改�Q�在我们的服务器上依然存在上面的问题�Q�不知道其它版本的Linux�pȝ��是否可以解决。遇到相同问题的人可以尝试一下这�U�办法�?br />
         �?1�q�个版本中，启动时已�l�不会出现这个问题了。但是当服务启动了之后，我在本地计算��Z��无法讉K��。但是在服务器上通过localhost可以正常使用。这个问题可能是防火墙的问题�Q�于是加入了相应的规则，但是依然无法讉K��。后来，�l�过��阅资料�Q�得知如果是服务器上有多个网卡，需要对其进行绑定。否则，只能通过localhost来访问。原来是�q�样�Q�在服务器上通过��览器，在管理员界面加入了相应的规则。重启服务，哈哈�Q�终于可以访问了�Q?br />
         最后，可以在sample��面�Ҏ��持的��媒体格式进行测试。在��试的时候，�q�有一些小的插曌Ӏ�因为我们现在多��C�h用的是暴风媄韻I��像我��根本没有安装realplayer。所以，开始是出现rmvb格式的媒体无法观看的问题。后来重新安装了realoneplayer之后解决了上�q�问题。另外一个让我弄了一个多��时的问题是�Q�无法播放MP3格式的文件。最后，把用来播放MP3的插件——mp3fformat.so的文件从Plugins目录�U�d��Q�重启系�l�，再移入，重启�pȝ��。后来就可以播放了。具体原因还不知道�ؓ什么：�Q�不��怎么��P��最后是大功告成了，可以正常使用了�?br />
         接下来的��d��是讄��加蝲点，使用ftp目录中的媒体来供教研室的同学讉K��了�?br />
PS�Q�Helix��g��不支持中文，所以接下来可能要作一件事情，��是如何��中文文件名可以被��用�?/p>
