• Edit /etc/default/dhcp.agent and remove '12' from the last second line which means hostname
• Create /etc/nodename and put your node name such as solarisdev in it.
• Add 127.0.0.1      localhost    loghost    solarisdev
• svcadm disable physical:default;  svcadm enable physical:nwam  (network auto magic)
• Unplug your network cable and reboot (dhcp will cache your network configuration)
  

1. Process Accounting

Process accounting is performed by the system kernel. Upon termination of a process, one record per process is written to a file (normally /var/adm/pacct). The accounting information is initiated when creating one new process using fork(2). exec(2) will not create accounting information, even though it will change the program name in accounting structure.

• accton(1M): specify on/off the accounting file which will be written process accounting information.
• acctcom(1): search and print process accounting files. It reports only on processes that have terminated; use ps(1) for active processes.
  

2. User Accounting

•  /var/adm/utmpx: this database file contains user access and accounting information for commands such as who(1), write(1) and login(1). It contains current user and accounting information.
  
• /var/adm/wtmpx: this database contains the history of user access and accounting information for the utmpx database. last(1) command use this file to report user login/logout activity. (last reboot can give a record of when the OS was shutdown and when it rebooted.
  

3.Extended accounting

Extended accounting perform accounting not only on process but also on task and flow(IPQos)

• acctadm: Run acctadm with no arguments will display the current accounting status.
• acctadm -r: display available resource groups.
• -d resource_list/-D/-e resouce list/-E/-x: disable/enable accounting.
• lastcomm(1) displays the last commands executed, in reverse order. If extended process accounting is active and is recording the appropriate data items, lastcomm attempts to take data from the current extended process accounting file(normally /var/adm/exacct/proc). If standard process accounting is active, last comm takes data from the current standard accounting file (normally /var/adm/pacct).
  

由于 Solaris 默认不安装 vim 而使用老古董级的 vi，因此如果想使用vim的强大功能，需要自己安装，有几个安装方式：

• 从 www.sunfreeware.com 下载包并安装，这种方式需要手动安装很多依赖包，且默认没有ruby支持。
• 从 www.blastwav.org 使用 pkg-get 来安装，这种方式会自动安装依赖包，而且也没有ruby支持。
• 自己编译源代码

下面介绍一下如何使用编译源代码方式来安装 vim。

0。安装 SunStudio 11 和 cbe 环境

• SunStudio 11是一个功能强大的编译器，获得过很多奖项，其安装比较简单，请参见http://www.opensolaris.org/os/community/tools/sun_studio_tools/sun_studio_11_tools/
• cbe(common build enviroment) 是一个编译环境， 其安装请参见 http://www.opensolaris.org/os/project/jds/contributing/building/
  

1。安装 ncurses

由于 vim 需要使用 ncurses 来实现丰富多彩的字符颜色显示，因此首先需要安装 ncurses 库。

• 下载 ftp://ftp.keystealth.org/pub/gnu/gnu/ncurses/ncurses-5.6.tar.gz
• gzcat ncurses-5.6.tar.gz |tar -xvf -
• cd ncurses-5.6.tar.gz
• ./configure --prefix=$HOME; make ; make install

2。如果需要ruby编辑支持，需要安装ruby

参见 http://blogs.sun.com/yydzero/entry/%E5%9C%A8_solaris_express_%E4%B8%8A%E7%BC%96%E8%AF%91_ruby 

3。安装 vim

•  下载 vim 源代码：http://www.vim.org/download.php#unix
•  cd vim/src
•  如果你的 ncurses 库不是在标准的库路径 /usr/lib:/lib 那么需要export两个环境变量
• export LDFLAGS=-L/path/to/your/libncurses.so
• export LD_LIBRARY_PATH=/path/to/your/libncurses.so
•  ./configure --prefix=$HOME --disable-gui --without-x --disable-acl --enable-perlinterp --enable-pythoninterp --enable-rubyinterp --enable-cscope --with-ncurses=$HOME
•  make
•  make install

4. 运行 vim

    如果你的 ncurses 库不是在标准的库路径中，那么需要在运行vim之前 export LD_LIBRARY_PATH。 但是每次这样做是非常繁琐的，为了避免每次设定，可以在 $HOME/.bash_profile 中加入 alias vi='LD_LIBRARY_PATH=/path/to/your/ncurses.so /path/to/your/vim'，这样每次运行vi时会自动export LD_LIBRARY_PATH. 使用 :version 查看版本信息。

• 从 ruby-lang.org 下载 ruby 1.8.6  源代码.
• 编辑 configure 文件，找到 for ac_func in dup2 ... isnan isinf fnite ...部分，删除掉 isinf。否则在编译 missing/isinf.c文件时会报告 __builtin_isinf 相关的一个错误。原因是 configure 在测试系统上的 isinf 函数时没有传递任意参数给 isinf 而造成编译失败。因为我们知道系统上有该函数，所以删除对它的测试不会影响ruby的运行。
  
• ./configure --enable-install-doc --enable-shared
• 不要使用 --enable-pthread 选项，否则会报告错误，由于目前对使用pthread不是很关心，所以没有找workaround。如果您知道workaround，烦请告知。
  
• make
• make install

As UTF-8 becomes the most popular encoding, many operating system such as solaris, ubuntu are using UTF-8 as the default locale. Then how to handle the large amount of legacy encoded file(filename/filecontent)? There are several tools available, let's have a look.

1.  find some directory and ignore some other directory:  find . -name ignoreDir -prune -o -name \*.iso -print
