Posting douban saying using python / 用python發送豆瓣廣播

Finally I got sometime to work on implementing my own python script for posting douban saying, again. This time I used the library written by Leah Culver, and everything went smoothly. It’s just that I have no idea why douban chose to use a different signing algorithm(if a thing as stupid as it is can be called a algorithm) for requesting access token.

終於又有時間再一次捯鼓豆瓣. 這次在 Leah Culver 寫的 library 的基礎上, 終於把python腳本發送豆瓣廣播終於搞定了. 唯一理解不能的事就是豆瓣在獲取access token的時候用了一個莫名其妙的簽名算法(如果這種也能叫做算法的話 = =).

iptables port forwarding for emule

Suppose you wanna have HighID and open KAD network connection for eMule on a computer in a LAN, and the gateway is running iptables. Just add the rules below to your existing iptables rules and you are done.

# this example is based on the assumption that 
# eth0 is WAN interface and eth1 is LAN interface,
# is the ip address of a computer in LAN,
# 4262 is the tcp port for ed2k network,
# 4272 is the udp port for kad network.

-A PREROUTING -i eth0 -p tcp -m tcp --dport 4262 -j DNAT --to-destination
-A PREROUTING -i eth0 -p udp -m udp --dport 4272 -j DNAT --to-destination

-A FORWARD -d -i eth0 -o eth1 -p tcp --dport 4262 -j ACCEPT
-A FORWARD -d -i eth0 -o eth1 -p udp --dport 4272 -j ACCEPT
