Platform

Complete interface lifecycle management

From provisioning to decommission, Uplink gives you deterministic control over every interface in your infrastructure.

Interface Discovery

Automatically detect and catalog every network interface across your fleet. Supports eth, wlan, lo, tun, br, veth, and bond devices — including alias interfaces like eth0:0.

IP Configuration

Assign IPv4 and IPv6 addresses, set netmask and broadcast addresses, configure point-to-point links, and manage subnets — all through a unified control plane.

Traffic Metrics

Real-time visibility into RX/TX packets, bytes, errors, drops, overruns, frame errors, and carrier loss. Per-interface, per-second granularity with historical rollups.

Promiscuous Mode Control

Toggle promisc and allmulti modes with full audit trails. Enforce security policy by preventing unauthorized packet capture across the fleet.

Hardware Address Management

Set and rotate MAC addresses with hw ether support. Manage Ethernet, AX.25, ARCnet, and NET/ROM hardware classes from a single interface.

MTU & Queue Tuning

Fine-tune Maximum Transfer Unit and transmit queue length per interface. Optimize for latency-sensitive workloads or high-throughput bulk transfers.

Configuration Wizard

Deploy interface configs in seconds

Our step-by-step wizard generates production-ready ifconfig commands for any interface scenario.

How It Works

Three steps to managed interfaces

Deploy Uplink across your fleet in minutes.

Install Agent

Deploy the lightweight Uplink agent to every host. It immediately discovers all network interfaces — active, down, and aliased — and reports to the control plane.

Define Policies

Set IP assignments, MTU values, promiscuous mode rules, and MAC address policies. Uplink enforces configuration state declaratively across your infrastructure.

Monitor & Optimize

Track RX/TX throughput, packet errors, drops, and overruns in real time. Receive alerts on anomalies and auto-tune queue lengths for optimal performance.

Open Source

Built on `uplink`

Uplink is a managed layer on top of the battle-tested uplink utility from net-tools. We didn't reinvent network configuration — we made it enterprise-grade.

The uplink command has been configuring kernel-resident network interfaces since the early days of Unix. It supports IPv4, IPv6, AX.25, Appletalk, IPX, and NET/ROM address families.

Every Uplink operation maps to deterministic ifconfig invocations — no magic, no abstraction leaks.

Trusted by infrastructure operators

"Before Uplink, our team was SSH-ing into 400 hosts to change MTU values. Now we push a single policy and it propagates in under 50ms. This is what infrastructure management should feel like."

Karim Rahal VP Infrastructure, Nimbus Cloud

"The traffic metrics alone paid for Uplink. We caught a misconfigured interface dropping 12% of packets before it impacted production. The promiscuous mode audit trail is a compliance lifesaver."

Casey Thornton Network Architect, Stratos Systems

"We manage 3,000 interfaces across bare metal and containers. Uplink's discovery found 47 orphaned alias interfaces we didn't even know existed. The Configuration Wizard alone saves us 6 hours a week."

Caleb Walsh SRE Lead, PacketForge

FAQ

Frequently asked questions

What interface types does Uplink support?

Uplink supports all Linux network interface types: Ethernet (eth), wireless (wlan), loopback (lo), tunnel (tun/tap), bridge (br), virtual Ethernet (veth), bond devices, and alias interfaces (e.g. eth0:0). We also support AX.25, ARCnet, and NET/ROM hardware classes.

How does Uplink handle IP address assignment?

Uplink manages IPv4 and IPv6 address assignment declaratively. Set IP addresses, netmasks, broadcast addresses, add/remove addresses with prefix lengths, and configure point-to-point links — all versioned and auditable.

Can I control promiscuous mode fleet-wide?

Yes. Uplink provides centralized policy for promiscuous mode and all-multicast mode. You can enforce strict no-promisc policies, allow it on designated monitoring interfaces, and generate audit reports for compliance.

What traffic metrics are available?

Uplink exposes all kernel interface statistics: RX/TX packets, bytes, errors, drops, overruns, frame errors, carrier loss, collisions, CRC errors, and FIFO overflows. Data is collected per-second with configurable retention.

Does Uplink replace ifconfig?

No — Uplink is a management layer built on top of ifconfig (and ip from iproute2). Every operation we perform maps to a deterministic ifconfig or ip invocation. We add fleet-scale orchestration, metrics, policy enforcement, and audit trails.

Is the `ifconfig -a` equivalent available?

Absolutely. The Uplink dashboard shows all interfaces by default — active, down, and unconfigured — equivalent to uplink -a. You can filter by status, type, host, or tag.
