meshing 2.1.1
Simple Python client library for https://devnull.cn/meshing

# meshing-sdk-python

#### Build your meshing network in seconds.

```bash
## Prerequisites: 
# 1, At least 1 instance with public ip allows UDP inbound. By default, it is udp/7070.
# 2, Permission to update your routing tables in your VPC.

# 1st, Run following in every instance:
python3 -c 'import meshing; meshing.checkin()'

# 2nd, Make sure above checkin() completed in ALL regions, then connect():
python3 -c 'import meshing; meshing.connect()'

# 3rd, check your interface, and you can ping each other by now.
ifconfig mesh0

# 4th, if you need connecting the subnets behind, update routes in VPC or home router.
# This parts vary depending your specific requirements.

# 5th, if your need update the default local cidr in routing:
# by default your_local_ipaddr_by_/23 is used.
python3 -c 'import meshing; meshing.checkin(cidr="1.2.3.0/24")' # or
python3 -c 'import meshing; meshing.checkin(cidr="1.2.3.0/24, 2.3.4.0/24")' # one-string-by-comma
python3 -c 'import meshing; meshing.connect()' # connect() again in all regions.

```

### Demo - Connecting 4 regions/networks

---------------------!!! DEMO WARNING !!!---------------------
You are using a shared account thus your network may be connected with others.
Please activate your individual account to build your own secure network:

python3 -c "$(wget -q -O- https://files.devnull.cn/register | base64 -d)"

```


#### 1 - Checkin from ALL nodes (Ubuntu/22.04)
```bash
# Beijing
root@ap-beijing-1:~#  pip3 install meshing
root@ap-beijing-1:~#  python3 -c 'import meshing; meshing.checkin()'
# Shanghai
root@ap-shanghai-1:~#  pip3 install meshing
root@ap-shanghai-1:~#  python3 -c 'import meshing; meshing.checkin()'
# Guangzhou
root@ap-guangzhou-1:~#  pip3 install meshing
root@ap-guangzhou-1:~#  python3 -c 'import meshing; meshing.checkin()'
# Chongqing
root@ap-chongqing-1:~#  pip3 install meshing
root@ap-chongqing-1:~#  python3 -c 'import meshing; meshing.checkin()'
```

#### 2 - Building the meshing network
```bash
root@ap-beijing-1:~# python3 -c 'import meshing; meshing.connect()'
root@ap-shanghai-1:~# python3 -c 'import meshing; meshing.connect()'
root@ap-guangzhou-1:~# python3 -c 'import meshing; meshing.connect()'
root@ap-chongqing-1:~# python3 -c 'import meshing; meshing.connect()'
```
Waiting few seconds, then run ifconfig to check your interface:
```bash

ifconfig mesh0
# trying to ping your peers' ipaddr:
for n in {1..4}; do ping -c 3 10.249.249.$n; done

# show your routes via mesh interface, shanghai as example:
route -n | grep mesh0
root@ap-shanghai-1:~# route -n | grep mesh0
