Tailscale open-sources Tailcat: No login or IP assignment required, enabling direct tunneling between two machines

40 minutes ago

From Beating AI Express: Tailscale has open-sourced Tailcat, a tool that allows two machines to connect directly without signing up for an account or joining the same Tailnet—all you need is a single address string. It retains Tailscale’s WireGuard encryption, NAT traversal, and DERP relay functionality, but eliminates the need for a Tailscale account or control plane. Running Tailcat on one machine generates a connection address string; sharing this with another machine enables file transfers, port forwarding, or SSH access. Connections first use DERP to locate the peer, then attempt a direct peer-to-peer UDP connection; if hole punching fails, traffic falls back to the DERP relay. The entire process runs in user space, with no modifications to system routes or DNS settings. Tailscale lead engineer Brad Fitzpatrick first built a Tailcat prototype back in 2023, but the project was largely sidelined. He revived it recently as AI agents began connecting en masse to sandboxes, remote VMs, and test machines. Fitzpatrick uses Tailcat to let agents connect temporarily to Raspberry Pi devices, EC2 instances, and Windows hosts—no pre-configured accounts or network access for the agents required. Tailcat is not a full replacement for Tailscale: it lacks user identities, permission policies, and device management, and its connection address must be treated like a password. Tailscale-hosted Tailcat DERP relays log metadata, have rate limits, and do not offer uptime SLAs; for greater stability or privacy, users can deploy their own DERP relays.

Wintermute: BTC’s Short-Term Direction Hard to Judge, September FOMC Will Be Key Catalyst

Wintermute stated in a report that Warsh’s speech at the Jackson Hole Annual Meeting has pushed market expectations for a September interest rate hike to 61.9%. The September 15-16 FOMC meeting will serve as a key catalyst for risk assets, including the crypto market. In August’s cross-asset performance: 20+ year US Treasuries rose 1.01%, the S&P 500 gained 0.47%, Nasdaq advanced 0.42%, BTC climbed 0.10%, ETH dropped 0.86%, while gold and Brent crude oil rose 3.42% and 4.31% respectively. Over the past week, BTC has consolidated its prior 23% rally, briefly breaking above $81,000 before falling back below $78,000 after Warsh’s speech, ending the week up 0.10%. Wintermute noted that despite the Fed’s hawkish remarks, a pullback in chip stocks, and month-end factors, BTC has not reversed its earlier breakout, with overall performance remaining relatively positive. However, $82,000 has repeatedly acted as a resistance zone. Current underallocation to BTC by some investors remains an important support for its price. BTC’s key current levels are $75,000 (support) and $82,000 (resistance); if it closes below $72,000 on a weekly basis, there will be no clear support below that level. In the short term, a healthier move would see BTC retest the $75,000 level, complete deleveraging, before attempting to break higher. Wintermute added that the first two weeks of September will significantly impact market direction. The non-farm payrolls data due September 4 could notably shift interest rate expectations ahead of the FOMC meeting. Two key signals will be watched for any change in its outlook: weekly net outflows from BTC ETFs, or a weekly close of BTC below $72,000.
