1. Edge can view the IP address and socket information of the connected tap adapter through the management console (127.0.0.1:5644);
2. Repair two memory leaks;
3. Fix several code errors and redundant logic;
1. Automatically assign IP addresses to the edge through the DHCP function that comes with sn, the default IP address pool is 172.17.12.0/24.
2. The -d parameter is added to sn, and the IP address pool of the embedded DHCP can be customized.
3. Now edge does not need to add -a and -s parameters to automatically obtain the IP address.
4. The IP automatically obtained by the cross-community edge can be the same, because the communities are isolated from each other and do not interfere with each other.
5. On the management side of sn (127.0.0.1:5645), you can now view the IP address of the tutap adapter of each edge.
6. Fix many bugs that have a certain chance of causing memory leaks.
7. Note: This version is not fully compatible with the previous version.
It seems the previous `route.net_addr == INADDR_NONE` check was incorrect and was probably a result of copy-pasting the previous if statement and not changing the condition.
