SNAT 的設定方式

echo "Setting IP Masquerading and HD parameters...."

echo 1 > /proc/sys/net/ipv4/ip_forward

/sbin/iptables -F

/sbin/iptables -t nat -F

/sbin/iptables -P FORWARD DROP

# Block access to208.46.65.0/24

/sbin/iptables -A OUTPUT -d 208.48.65.0/24 -j DROP

/sbin/iptables -A FORWARD -s 192.168.0.0/24 -j ACCEPT

/sbin/iptables -A FORWARD -d 192.168.0.0/24 -j ACCEPT

將 Wav 轉成 mp3 之 命令

for i in *.wav; do lame --preset standard $i `basename $i .wav`.mp3; done

Linux用mencoder抽取影片檔中的音頻轉為mp3

mencoder -o movie.mp3 -ovc frameno -oac mp3lame -lameopts cbr:br=128 -of rawaudio -ss mm:ss -endpos MM:SS movie.avi

Ubunto 10.04 上使用 hinedo

update_hinedo.sh

#!/bin/sh
#=============================
export LANG="zh_TW.UTF-8"
export LANGUAGE="zh_TW.UTF-8"
export LC_ALL="zh_TW.UTF-8"

rm -rf ~/.config/hinedo/*
/usr/lib/hinedo/update
~/.config/hinedo/update_menu
#=============================

把字幕檔和影片檔合一

先將字幕檔由 BIG5 轉成 UTF8

iconv -f BIG5 -t UTF8 -o UTF8.txt Video.srt.txt

將 AVI 及字幕檔合而為一
mkvmerge -o 1.mkv Video.avi UTF8.txt

ubuntu 10.04 改用 scim

改 /etc/alternatives/xinput-zh_TW 指到 /etc/X11/xinit/xinput.d/scim
