软件包摘要
TCP over DNS tunnel
历史
项目历史与用法
dns2tcp is a client/server tool for relaying TCP connections over DNS. It belongs to the older family of DNS-tunneling utilities used for constrained networks, demonstrations, and security testing rather than general-purpose VPN service.
项目历史
The upstream ChangeLog marks version 0.3 as the public release and records later fixes for 64-bit architectures, DNS decoding, privilege dropping, client authentication, and Windows client support. The README is explicit that DNS encapsulation is not encrypted and should be treated as an insecure transport.
采用历史
dns2tcp stayed visible because it solves one very specific network problem with small C tools: a client, a server, and simple resource mappings. Distribution packaging kept it available for administrators and security testers who need a TCP-over-DNS tunnel without a broader VPN stack.
使用方式
The README shows using dns2tcpc to list available remote resources, bind a local port to a remote service, or run from ~/.dns2tcprc. Server use centers on ~/.dns2tcpdrc, where the operator defines the DNS domain, key, and named resources such as ssh or smtp targets.
为什么软件包爱好者会关心
Package nerds care about dns2tcp because it is a classic small-network-tool package: narrow, risky if misunderstood, but valuable in labs and incident-response toolboxes because it demonstrates TCP-over-DNS behavior with minimal moving parts.
时间线
- 0.3: Public release.
- 0.4: 64-bit architectures start working.
- 0.5: Client authentication, Windows client support, and proxy-style use are added.
- 0.5.2: OpenSSL includes are removed after earlier library cleanup.
Related projects
- iodine is a related DNS-tunneling project focused on IP-over-DNS rather than TCP-over-DNS.
- ssh ProxyCommand workflows are a common adjacent use case for dns2tcpc.
