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。

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。
