n2n为超级节点和边缘设置DHCP，获得未知主机

如何解决n2n为超级节点和边缘设置DHCP，获得未知主机

我在AWS上有两个ubuntu实例，一个是 supernode ，另一个是使用n2n的 edge 。我试图连接也托管在超级节点上的dhcp服务器，以便在加入时可以自动分配边缘的ip。

在超级节点上，我安装了：

sudo apt install isc-dhcp-server

我的/etc/dhcp/dhcpd.conf：

ubuntu@ip-172-31-31-176:~$ cat /etc/dhcp/dhcpd.conf
# dhcpd.conf
#
# Sample configuration file for ISC dhcpd
#
# Attention: If /etc/ltsp/dhcpd.conf exists,that will be used as
# configuration file instead of this file.
#

# option definitions common to all supported networks...
authoritative;

default-lease-time 3600;
max-lease-time 7200;

subnet 192.168.233.0 netmask 255.255.255.0 {
        option subnet-mask 255.255.255.0;
        range dynamic-bootp 192.168.233.1 192.168.233.255;
}

我的/etc/default/isc-dhcp-server：

INTERFACES="A5TAP" #added by myself just to test if it helps
INTERFACESv4="A5TAP"
INTERFACESv6=""

在端口1234上运行超级节点：

supernode -l 1234

然后在超级节点上运行边缘以连接我的DHCP服务器：

sudo edge -r -d A5TAP -c a5 -k mykey -a 192.168.233.0 -l 127.0.0.1:1234

然后我重新启动dchp服务器： sudo service isc-dhcp-server restart

检查日志以查看是否成功： sudo systemctl status isc-dhcp-server.service 它是：

ubuntu@ip-172-31-31-176:~$ sudo systemctl status isc-dhcp-server.service

然后在我的边缘：

sudo edge -r -d A5TAP -c a5 -k mykey -a dhcp:192.168.233.0 -l my-super-node-ip:1234

但是我得到了unknown host：

dhcp:192.168.233.0: Unknown host
ifconfig: `--help' gives usage information.
17/Oct/2020 13:17:20 [tuntap_linux.c:  38] Interface A5TAP has MAC 12:13:17:11:4F:AA

我尝试过的事情：

我试图ping -c 1 192.168.233.0处于优势，但得到了

ubuntu@ip-172-31-21-149:~$ ping -c 1 192.168.233.0
Do you want to ping broadcast? Then -b. If not,check your local firewall rules.

因此，我尝试再次执行上述步骤，并将超级节点上的边缘（dhcp服务器）IP从192.168.233.0更改为192.168.233.1。结果相同。 我还手动将ip分配给了我的边缘以加入超节点，因此我可以测试192.168.233.1是否可以访问以及是否可以访问。 在边缘：

sudo edge -r -d A5TAP -c a5 -k mykey -a 192.168.233.2 -l super-node-ip:1234

ping -c 1 192.168.233.1

输出：

ubuntu@ip-172-31-21-149:~$ ping -c 1 192.168.233.1
PING 192.168.233.1 (192.168.233.1) 56(84) bytes of data.
64 bytes from 192.168.233.1: icmp_seq=1 ttl=64 time=0.328 ms

将dhcp服务器添加到我的超级节点和n2n中的边缘时，我做错了吗？
