| description | Access the Crosstown residence local network via the MacBook Pro. Use when needing to reach Crosstown LAN devices, run commands at Crosstown, scan the local network, interact with the AmpliFi router, Hue Bridge, Ring Doorbell, or any device on the 192.168.165.x subnet. Also use for presence detection at Crosstown. |

Crosstown Network Access
The OpenClaw gateway runs on the cabin Mac Mini (dylans-mac-mini). To reach devices on the Crosstown residence local network, SSH into the MacBook Pro there.

Scanning for Devices
ARP scan from the MacBook Pro (ping sweep first to populate ARP table):
ssh dylans-macbook-pro "for i in \$(seq 1 254); do ping -c1 -W1 192.168.165.\$i >/dev/null 2>&1 & done; wait; arp -a | grep -v incomplete | grep '192.168.165'"
Check a specific device:
ssh dylans-macbook-pro "ping -c3 -W2 192.168.165.124; arp -anl | grep '^192.168.165.124 '; arp -a | grep 192.168.165.124"
Presence Detection
Track phone presence by probing the LAN and requiring live receive-side
reachability from arp -anl before matching a MAC or exact hostname:
| Person | Hostname | MAC (Crosstown WiFi) | IP |
|---|
| Dylan | dylans-iphone | ${CROSSTOWN_DYLAN_MAC} | 192.168.165.124 |
| Julia | julias-iphone | ${CROSSTOWN_JULIA_MAC} | 192.168.165.248 |
Matching priority: MAC → exact hostname (mDNS .lan name joined to the same
fresh IP/MAC/interface row). IP alone is not accepted as identity. Hostname is
the durable fallback when iOS rotates its per-network MAC.
iPhones in sleep mode may ignore ICMP while still answering ARP. The presence
scanner therefore ignores ping exit status and trusts only a live inbound
reachability timer; cached complete rows with expired inbound reachability do
not count.
Bonjour Discovery
Find Apple devices broadcasting on the Crosstown LAN:
ssh dylans-macbook-pro "dns-sd -B _companion-link._tcp local. & PID=\$!; sleep 5; kill \$PID 2>/dev/null"
Find Google/Nest speakers:
ssh dylans-macbook-pro "dns-sd -B _googlecast._tcp local. & PID=\$!; sleep 5; kill \$PID 2>/dev/null"
Remote Maintenance Safety
Do not run diskutil verifyVolume /System/Volumes/Data or another full APFS check over the
MacBook Pro's only SSH/Tailscale management path. A live verification of the 648 GiB Data
volume made the host stop answering Tailscale traffic on 2026-06-22, which also interrupted
presence scans and Crosstown device bridges.
For unattended remote checks, limit storage inspection to SMART status, free space, panic
reports, and service health. Run startup/Data-volume First Aid only while physically on site
or when a second independent management path is available. Keep and wait on the original
command session; never start a second filesystem verification because streamed output ended
before the final status arrived.
Limitations
- SSH required — all commands must be wrapped in
ssh dylans-macbook-pro "..."
- PATH note — Homebrew's
/opt/homebrew/bin is in the system PATH via /etc/paths.d/homebrew, but for npm use PATH=/opt/homebrew/bin:$PATH npm ...
- Sleep disabled —
pmset disablesleep 1 is set so the machine stays reachable
