====== SSHD ======
啟動系統內建的 SSH Server
  # vim /etc/rc.conf

增加一行：
  sshd_enable="YES"

  # /etc/rc.d/sshd

====== .cshrc ======
安裝 gnuls
  # cd /usr/ports/misc/gnuls ; make install clean

<code>
alias ls gnuls --color=auto

setenv  EDITOR  vim
setenv  PAGER   less
setenv  BLOCKSIZE       K

set prompt = '%n@%m:%~%# '
</code>

====== make.conf ======
複製 make 的設定檔(若檔案已經存在就不需要)。
  # cp /usr/share/examples/etc/make.conf /etc/

修改 make.conf，新增 MASTER_SITE_BACKUP 及預設語系等設定。
<code>
# CVSup update flags.  Edit SUPFILE settings to reflect whichever distribution
# file(s) you use on your site (see /usr/share/examples/cvsup/README for more
# information on CVSup and these files).  To use, do "make update" in /usr/src.
#
SUP_UPDATE=yes
#
SUP=            /usr/local/bin/csup
SUPFLAGS=       -g -L 2
SUPHOST=        cvsup.tw.FreeBSD.org

   ftp://freebsd.csie.nctu.edu.tw/pub/distfiles/${DIST_SUBDIR}/
MASTER_SITE_OVERRIDE?=    ${MASTER_SITE_BACKUP}

... ... ...

WITHOUT_X11=yes
WITH_CHARSET=utf8
WITH_XCHARSET=complex
</code>

====== pkg_add ======
如果執行 pkg_add -r xxxxxx 時出現：
<code>
Error: FTP Unable to get ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-6-release/Latest/xxxxxx.tbz: File unavailable (e.g., file not found, no access)
pkg_add: unable to fetch 'ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-6-release/Latest/xxxxxx.tbz' by URL
</code>

代表套件庫裡面找不到檔案，可先到 ftp://ftp.tw.freebsd.org/pub/FreeBSD/ports/i386/ 網址確認有哪些版本可用，然後執行
  # setenv PACKAGESITE ftp://ftp.tw.freebsd.org/pub/FreeBSD/ports/i386/packages-X-release/Latest/
  將 X 替換成適合的值

來更換預設的套件下載站。

====== portupgrade ======
===== 換版本分之 =====
原本一直使用的主要版本，有可能會因為版本大更新，而做出一個分支，但是不想要換太大，可以透過 portupgrade 來切換到分支版本。例如：postfix 分支從 2.6 升級到 2.8，並且另外獨立了一個 postfix26 分支出來，此時可透過

  portupgrade -o mail/postfix26 postfix

指令，將 postfix 的版本維持在 2.6 版。

另外，由 php5 要保持在 php52，要升級的套件非常龐大，可以利用別人寫好的 bash 語法來完成：

for d in `portversion -vL= | grep php5 | awk '{print $1}'`; do  OLD=`echo $d | cut -d - -f 1,2`; NEW=`echo $d | sed s/php5/php52/ | cut -d - -f 1,2`; THEPATH=`whereis $NEW | awk '{print $2}' | cut -d / -f 4,5`; echo "portupgrade -o $THEPATH $OLD && \\"; done

會產生所有需要升級的指令，將結果複製貼上去執行就可以了！

====== Port 安裝時 MD5/SHA256 錯誤 ======
如果在 Ports 編譯時，出現類似訊息：
<code>
# make
===>  Extracting for py26-sqlite3-2.6.2_1
=> No MD5 checksum recorded for python/Python-2.6.2.tgz.
=> No SHA256 checksum recorded for python/Python-2.6.2.tgz.
=> No suitable checksum found for python/Python-2.6.2.tgz.
*** Error code 1

Stop in /usr/ports/databases/py-sqlite3.
</code>

代表 /usr/ports/distfiles/python/Python-2.6.2.tgz 檔案下載時錯誤，刪除後重編就可以了。

根據出現錯誤的套件，刪除相對的檔案。
