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    
    退格(Backspace)    
e    转义    
000    空    

    换行    
v    纵向制表符    
	    横向制表符    

    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 == '':
                   cmd=cmd[:-1]
                else:
                    cmd+=x
                #records.append(x)
                if x == '
':
                    #print "your input is:",cmd
                    log_line = "-login_user:%s	|host_addr:%s	|%s|HISTORY_CMD: %s 
" % (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  "33[33;1m########################################################33[0m"
        awk '{printf "33[35;1m%s:	[%-4s]	%20s	%s33[0m
",NR,$2,$1,$NF}' remote_ip.log
        echo  "33[33;1m########################################################33[0m
"
}
wai_t(){
        echo  "33[32;1m before choose items will be sleep a monent33[0m
"
       # for i in {1..3};do sleep 0.6 && echo -e "33[35;1m..........................33[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:	[%10s]	%-20s	%s
",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。
