python的paramiko源码修改了一下，写了个操作命令的日志审计 bug修改

python的paramiko源码修改了一下，写了个操作命令的日志审计，但是记录的日志中也将backspace删除键记录成^H这个了，于是改了一下代码，用字符串的特性。

字符串具有列表的特性

>>> a="hello world"
>>> a[:-1]
'hello worl'

转义符

转义字符
\(在行尾时)    续行符    

\\    反斜杠符号
\'    单引号
\"    双引号
\a    响铃
\b    退格(Backspace)
\e    转义
\000    空
\n    换行
\v    纵向制表符
\t    横向制表符
\r    回车
\f    换页
\oyy    八进制数yy代表的字符，例如：\o12代表换行
\xyy    十进制数yy代表的字符，例如：\x0a代表换行
\other    其它的字符以普通格式输出

代码部分

            if sys.stdin in r:
                x = sys.stdin.read(1)
                if x == '\b':
                   cmd=cmd[:-1]
                else:
                    cmd+=x
                #records.append(x)
                if x == '\r':
                    #print "your input is:",cmd
                    log_line = "-login_user:%s\t|host_addr:%s\t|%s|HISTORY_CMD: %s \n" % (username,hostname,time.strftime("%Y_%m_%d %H:%M:%S"),cmd)
                    cmd = ''
                    log_file.write(log_line)

　shell 变量传入python脚本，修改后的源码脚本就不粘贴了。

root@python:~/baolei# cat remote.sh
#!/bin/sh
#created by liujianzuo
list(){
        #cd /home/liujianzuo/server/scripts
        echo  "\033[33;1m########################################################\033[0m"
        awk '{printf "\033[35;1m%s:\t[%-4s]\t%20s\t%s\033[0m\n",NR,$2,$1,$NF}' remote_ip.log
        echo  "\033[33;1m########################################################\033[0m\n"
}
wai_t(){
        echo  "\033[32;1m before choose items will be sleep a monent\033[0m\n"
       # for i in {..};do sleep 0.6 && echo -e "\033[35;1m..........................\033[0m";done
        #read -p "Please choose ip of top:" num
        while true
        do
                if [ -z $num ] && [ -z $username ];then
                        read -p "Please choose ip of top:" num
                        read -p "Please input your username:" username
                        continue
                else
                        break
                fi
        done
        IP=`awk -v ip=$num 'NR == ip{printf "%s:\t[%10s]\t%-20s\t%s\n",NR,$2,$1,$NF}' remote_ip.log|awk '{print $NF}'`
}
list
wai_t
python=`which python`
echo $username $IP
python demo.py $IP $username

还有几个bug要修改：

　　终端内切换ip，审计日志的ip要相应变化。

　　登陆服务器密码失败一次不退出。
