--- sidebar_position: 3 --- # Quick Start Get connected to the Mycelium network in under 5 minutes. ## Step 1: Connect to Public Peers Start your Mycelium node and connect to the global network: **Linux/macOS:** ```bash sudo mycelium --peers tcp://188.40.132.242:9651 quic://185.69.166.8:9651 ``` **Windows (as Administrator):** ```cmd mycelium --peers tcp://188.40.132.242:9651 quic://185.69.166.8:9651 ``` You should see output indicating Mycelium is starting and connecting to peers.
### 🔐 Why sudo/Administrator? Mycelium needs elevated privileges to create a network interface. This is standard for networking tools.
## Step 2: Get Your IPv6 Address Open a **new terminal** (keep Mycelium running in the first one) and check your node info: ```bash mycelium inspect --json ``` You'll see output like: ```json { "publicKey": "abd16194646defe7ad2318a0f0a69eb2e3fe939c3b0b51cf0bb88bb8028ecd1d", "address": "5c4:c176:bf44:b2ab:5e7e:f6a:b7e2:11ca" } ``` **Save your address** - this is your unique Mycelium IPv6 address that others will use to reach you. ## Step 3: Test Connectivity Ping one of the public peers to verify connectivity: ```bash ping6 54b:83ab:6cb5:7b38:44ae:cd14:53f3:a907 ``` If you see responses, congratulations! You're connected to the Mycelium network. ``` PING 54b:83ab:6cb5:7b38:44ae:cd14:53f3:a907(54b:83ab:6cb5:7b38:44ae:cd14:53f3:a907) 56 data bytes 64 bytes from 54b:83ab:6cb5:7b38:44ae:cd14:53f3:a907: icmp_seq=1 ttl=64 time=28.5 ms 64 bytes from 54b:83ab:6cb5:7b38:44ae:cd14:53f3:a907: icmp_seq=2 ttl=64 time=27.8 ms ``` ## Public Peers List Connect to these stable public peers for reliable connectivity: | Region | IPv4 | IPv6 | TCP/QUIC Port | Mycelium IP | |--------|------|------|---------------|-------------| | Germany | 188.40.132.242 | 2a01:4f8:221:1e0b::2 | 9651 | 54b:83ab:6cb5:7b38:44ae:cd14:53f3:a907 | | Germany | 136.243.47.186 | 2a01:4f8:212:fa6::2 | 9651 | 40a:152c:b85b:9646:5b71:d03a:eb27:2462 | | Belgium | 185.69.166.7 | 2a02:1802:5e:0:ec4:7aff:fe51:e80d | 9651 | 597:a4ef:806:b09:6650:cbbf:1b68:cc94 | | Belgium | 185.69.166.8 | 2a02:1802:5e:0:ec4:7aff:fe51:e36b | 9651 | 549:8bce:fa45:e001:cbf8:f2e2:2da6:a67c | | Finland | 65.21.231.58 | 2a01:4f9:6a:1dc5::2 | 9651 | 410:2778:53bf:6f41:af28:1b60:d7c0:707a | | Finland | 65.109.18.113 | 2a01:4f9:5a:1042::2 | 9651 | 488:74ac:8a31:277b:9683:c8e:e14f:79a7 | | US East | 209.159.146.190 | 2604:a00:50:17b:9e6b:ff:fe1f:e054 | 9651 | 4ab:a385:5a4e:ef8f:92e0:1605:7cb6:24b2 | | US West | 5.78.122.16 | 2a01:4ff:1f0:8859::1 | 9651 | 4de:b695:3859:8234:d04c:5de6:8097:c27c | | Singapore | 5.223.43.251 | 2a01:4ff:2f0:3621::1 | 9651 | 5eb:c711:f9ab:eb24:ff26:e392:a115:1c0e | | India | 142.93.217.194 | 2400:6180:100:d0::841:2001 | 9651 | 445:465:fe81:1e2b:5420:a029:6b0:9f61 | ## Connect to Multiple Peers For better reliability and performance, connect to multiple peers: ```bash sudo mycelium --peers \ tcp://188.40.132.242:9651 \ quic://185.69.166.8:9651 \ tcp://185.69.166.7:9651 \ quic://65.21.231.58:9651 ``` This creates redundant paths and improves network resilience. ## Keep Mycelium Running Mycelium needs to stay running to maintain your network connection. ### Run in Background **Linux/macOS:** ```bash # Using nohup nohup sudo mycelium --peers tcp://188.40.132.242:9651 quic://185.69.166.8:9651 & ``` **Better: Use systemd (Linux):** Create `/etc/systemd/system/mycelium.service`: ```ini [Unit] Description=Mycelium Network After=network.target [Service] Type=simple ExecStart=/usr/local/bin/mycelium --peers tcp://188.40.132.242:9651 quic://185.69.166.8:9651 Restart=always RestartSec=10 [Install] WantedBy=multi-user.target ``` Enable and start: ```bash sudo systemctl enable mycelium sudo systemctl start mycelium sudo systemctl status mycelium ``` **Windows:** - Use Task Scheduler to run at startup - Or run in a Command Prompt window kept open ## Basic Usage Examples ### SSH to Another Device If you have SSH running on another device with Mycelium: ```bash ssh user@5c4:c176:bf44:b2ab:5e7e:f6a:b7e2:11ca ``` ### Access a Web Service ```bash curl http://[5c4:c176:bf44:b2ab:5e7e:f6a:b7e2:11ca]:8080 ``` Note: IPv6 addresses must be in brackets for URLs. ### Connect Two Locations Run Mycelium on devices at both locations: - They'll automatically find each other through the mesh - Use their Mycelium IPs to communicate - All traffic is encrypted end-to-end ## Troubleshooting ### Can't Connect to Peers 1. **Check internet connection** - Verify you're online 2. **Firewall issues** - Mycelium should work behind NAT, but try temporarily disabling firewall 3. **IPv6 support** - Ensure IPv6 is enabled on your system 4. **Try different peers** - Some may be temporarily down ### Can't Ping Other Nodes 1. **Wait a few minutes** - Network discovery takes time 2. **Check peer connections** - Ensure you're connected to peers 3. **Verify the address** - Make sure you're pinging a valid Mycelium address 4. **Check logs** - Look for errors in the Mycelium output ### Permission Errors - **Linux/macOS**: Must run with `sudo` - **Windows**: Must run Command Prompt as Administrator - This is required to create the network interface ## What's Next?
