Glider
Glider is a multi-protocol forward proxy, transparent proxy gateway, and network service provider. It functions as a DNS and DHCP server, a Linux IP set manager, and a network traffic load balancer.
The project distinguishes itself through a protocol-translation bridge that translates traffic between different proxy schemes and a chain-based routing system that sequences multiple remote proxy servers. It supports transparent traffic interception at the system level and utilizes build-time protocol stripping to minimize the binary size of the executable.
The system covers a broad range of network management capabilities, including destination-based routing, multi-algorithm load balancing, and the automated population of kernel ipsets. It also provides DNS caching, high-availability IP leasing via DHCP, and health monitoring for network forwarders.
Features
- Traffic Interception - Captures system-level network traffic and redirects it through a proxy without requiring individual client configuration.
- Multi-Protocol Proxies - Functions as a multi-protocol proxy that routes traffic between different proxy schemes and transport protocols.
- DHCP and DNS Services - Provides integrated DHCP and DNS services for automatic IP assignment and hostname resolution on local networks.
- DNS Caches - Implements a DNS caching server with support for custom records and proxy-aware forwarding.
- Load Balancing Algorithms - Distributes network requests across multiple forwarders using round robin, destination hashing, or latency-based selection algorithms.
- Proxy Node Load Balancing - Distributes outgoing requests across multiple remote proxy servers using round-robin or latency-based selection.
- DNS Forwarding Routing - Runs a DNS forwarding server that supports caching, custom records, and routing queries over TCP or proxies.
- DNS Resolution - Fetches DNS answers from upstream servers with the option to route queries through a proxy.
- Conditional DNS Resolvers - Resolves domain names by routing queries to specific upstream servers or proxies based on defined routing rules.
- Proxy Routing Rules - Determines whether network requests are routed through a proxy or a direct connection based on destination lists.
- Protocol Translation Bridges - Translates network traffic between different proxy schemes by acting as both a client and a server simultaneously.
- Proxy Chaining - Sequences multiple remote proxy servers into a chain to control the outbound data path.
- External Proxy Forwarding - Routes network requests through external remote proxy servers using SSH, SOCKS5, or HTTP protocols.
- Proxy Scheme Translations - Translates network traffic between different proxy schemes and transport protocols by acting as both a client and a server.
- Destination-Based Routing - Maps specific network destinations to designated forwarders via rule files to control outbound paths.
- Proxy Chains - Provides a chain-based routing system to sequence multiple remote proxy servers for outgoing traffic.
- Transparent Proxying - Intercepts system-level network traffic to route it through proxies without requiring client-side configuration.
- IP Set Management - Automatically populates Linux kernel ipsets with IP addresses and CIDR ranges derived from DNS results and routing rules.
- DHCP Address Provisioning - Provides server-side provisioning of IP addresses to network clients in standard or failover modes.
- DHCP Servers - Operates a DHCP server supporting both standard and failover high-availability modes for IP address assignment.
- High Availability Synchronization - Ensures high availability of IP leases through a DHCP server with failover synchronization.
- Dynamic Rule Population - Dynamically updates proxy rules or kernel IP sets when new domains are discovered during DNS resolution.
- Network Transport Protocols - Provides secure and optimized data transfer using transport layers like TLS, WebSockets, and KCP.
- Local Proxy Interfaces - Hosts local entry points using HTTP, SOCKS5, and VLESS protocols to accept incoming network requests.
- Background Network Services - Executes background services to provide extended network functionality alongside proxy and DNS capabilities.
- Network Service Health Monitors - Performs periodic health checks on network forwarders using TCP, HTTP, or custom scripts to ensure reliability.
