Karatsuba Multiplication in C++
Code for ADSA Assignment1 Don’t copy it, or I can ensure you that you’ll get caught. Change some variable names ,swap order of some codes won’t help. I wrote two version just hope these will inspire your own coding. This program is designed for digits longer than what uint128_t can handle. (In this case, 100… Read more Karatsuba Multiplication in C++

zmap套装之zdns:批量查询域名ip
最近收到全球域名以后想做一个对应的ip list方便用Zgrab扫描 CSV格式： domain,”date added”,”NS servers”,”IP address”,country 用python预处理为一行一个域名： import csv with open(“all.csv”) as cfile: reader = csv.DictReader(cfile) f = open(“all.list”, “w”) for row in reader: print row.get(“domain”) f.write(row.get(“domain”) + “\n”) 安装zmap+Go+zdns yum install zmap git wget wget https://storage.googleapis.com/golang/go1.10.4.linux-amd64.tar.gz tar -C /usr/local -xzf go1.10.4.linux-amd64.tar.gz export PATH=$PATH:/usr/local/go/bin export GOPATH=/usr/local/go/bin/ go get github.com/zmap/zdns/zdns cd /usr/local/go/bin/src/github.com/zmap/zdns/zdns go build… Read more zmap套装之zdns:批量查询域名ip
Linux cp command in C
This is a simple implementation of cp command in linux, if you are student in University of Adelaide who happens to take SPC course, please do not copy this code directly. Code still can be optimized but I’m not gonna fix it since no mark will be given for coding style. CP命令的C实现~ Compile： gcc -o… Read more Linux cp command in C
利用Zgrab绕CDN找真实IP

Zgrab使用 Zgrab配和Zmap在200M带宽的机器上扫遍国区所有80端口大概是4小时以内（I7+16G+240G SSD RAID 0），网速和硬盘性能比较影响最终速度。至于扫全球的请准备好1T以上的SSD ./zgrab –help… Read more 利用Zgrab绕CDN找真实IP
ShadowSocks go mu + ss panel 添加节点
之前布置Panel+ss后台的时候遇上了不少麻烦 现需要在一台CentOS 7.2的机器上布置ss go mu并使用web api方式连接一台已经配置好的机器，通过redis授权。 首先 [code language=”bash”]yum install go screen git curl redis emacs[/code] 设置Go path： [code language=”bash”]export PATH=$PATH:/usr/local/go/bin export GOPATH=~/.go[/code] 安装ss go mu: [code language=”bash”]go get github.com/orvice/shadowsocks-go cd ~/.go/src/github.com/orvice/shadowsocks-go/mu go get go build[/code] 如果显示：package github.com/orvice/shadowsocks-go: no buildable Go source files in /root/.go/src/github.com/orvice/shadowsocks-go 请忽略 搞个配置文件出来： [code language=”bash”]cp example.conf ~/.go/bin/config.conf emacs ~/.go/bin/config.conf[/code] 其中client后为webapi方式连接（根据作者文档第二选择是mysql，如果使用了webapi，不用理会sql设置） 1.… Read more ShadowSocks go mu + ss panel 添加节点
