关于ubuntu的SSH连接数

[dreamflier]

由于服务器要提供给多人同时并发使用ssh做连接进行远程操作，想知道一下SHH的最大并发连接数是多少，在哪里可以设置修改，如果修改？
谢谢大家。

以下内容来自man sshd_config

代码： 全选

   MaxStartups
	     Specifies the maximum number of concurrent unauthenticated con-
	     nections to the sshd daemon.  Additional connections will be
	     dropped until authentication succeeds or the LoginGraceTime
	     expires for a connection.	The default is 10.

	     Alternatively, random early drop can be enabled by specifying the
	     three colon separated values "start:rate:full" (e.g.,
	     "10:30:60").  sshd will refuse connection attempts with a proba-
	     bility of "rate/100" (30%) if there are currently "start" (10)
	     unauthenticated connections.  The probability increases linearly
	     and all connection attempts are refused if the number of unau-
	     thenticated connections reaches "full" (60).
