Question 2

你可以使用 accel-ppp，因为它有一个非常强大的 cli。而且你可以毫无问题地断开特定用户的连接。

# telnet 127.0.0.1 2000
Trying 127.0.0.1...
Connected to localhost (127.0.0.1).
Escape character is '^]'.
accel-ppp version c0b2b260b2c9b8c3375d51e90cd1edf552d7655a
Password: ******

已通过主配置文件 accel-ppp.conf 配置了 ip 地址 127.0.0.1 和端口 2000

[cli]
telnet=127.0.0.1:2000
tcp=127.0.0.1:2001
password=1234567

要获取当前会话，您可以使用'显示会话' 命令

accel-ppp# show sessions
 ifname | username |  calling-sid  |       ip       | type | comp | state  |  uptime
--------+----------+---------------+----------------+------+------+--------+----------
 ppp0   | alex     | 192.168.1.7   | 192.168.216.10 | pptp | mppe | active | 00:32:50
 ppp1   | john     | 192.168.1.100 | 192.168.216.11 | l2tp | mppe | active | 00:00:49

要终止特定的一个，你可以使用'终止' 命令

accel-ppp# terminate username john soft

accel-ppp# show sessions
 ifname | username | calling-sid |       ip       | type | comp | state  |  uptime
--------+----------+-------------+----------------+------+------+--------+----------
 ppp0   | alex     | 192.168.1.7 | 192.168.216.10 | pptp | mppe | active | 00:34:57

终止命令有很多选项

terminate if <interface> [soft|hard]- terminate session by interface name
        [match] username <username> [soft|hard]- terminate session by username
        ip <addresss> [soft|hard]- terminate session by ip address
        csid <id> [soft|hard]- terminate session by calling station id
        sid <id> [soft|hard]- terminate session by session id
        all [soft|hard]- terminate all sessions

在日志文件 /var/log/messages 中你会看到
