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)

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。
