1.7.1

Hana - Network Utility v1.7.1

Bug Fixes

Subnet Sweep — CIDR input freeze
Entering an invalid CIDR and dismissing the error dialog caused
all inputs to become unresponsive. Fixed by validating before
setting running state and replacing the dialog with an inline
error banner.

Port Scanner — custom ports not returning results
Ports entered in the custom field were not appearing in scan
results when used alongside group presets. Fixed by ensuring
all port values are properly coerced to integers before scanning.

1.7.0

Hana - Network Utility v1.7.0

Electron Upgrade

Upgraded from Electron 33 to Electron 42 — the current latest stable release.
Brings security patches from nine major versions and Node 20 compatibility.

Input Validation & Error Banners

All modules now validate hostnames before running. Invalid inputs show
a clear red error banner immediately — no more silent failures or
stuck "running" states.

• Ping, Traceroute, DNS Lookup, Port Scanner — inline error banner
• Multi-Ping — invalid hosts show a red error card, valid hosts run normally

Security

• All Electron IPC handlers validate inputs server-side independently
• DNS lookups use per-request resolver instances (no global state mutation)
• Hostname validator blocks shell metacharacters across all modules

Reliability Fixes

• Stop Scan now correctly kills processes (fixed taskkill /pid undefined bug)
• Sweep listener cleanup no longer accumulates across multiple stop cycles
• Frontend error handling resets running state correctly on all modules

Subnet Sweep

• Results paginate at 254 — live hosts always shown first
• Expand button reveals all results for large CIDR sweeps

1.6.5

Hana - Network Utility v1.6.5

⚠ Security Fix

A shell injection vulnerability in the Subnet Sweep module has been resolved.
The base IP field previously passed user input directly into a shell command
string. This has been fixed by switching to argument-array subprocess calls
(no shell interpolation) and adding strict server-side IP validation.
All users on prior versions are encouraged to update.

New Modules

• ◈ DNS Lookup — resolve A, AAAA, CNAME, MX, TXT, NS, PTR records
  using Google, Cloudflare, or a custom internal DNS server
• ⊘ Port Scanner — scan TCP ports with pre-filled common ports,
  group presets, and custom port entry. Includes mandatory authorization
  disclaimer. Results show Open / Closed / Filtered

Subnet Sweep

• CIDR mode — sweep any subnet from /16 to /30
• Stop Scan button to cancel large sweeps immediately

Clear Buttons

Added ✕ Clear to Ping, Traceroute, DNS Lookup, Subnet Sweep, and Port Scanner

Bug Fixes

• Fixed export reports showing old "Look Look" branding
• Fixed CIDR sweep export showing incorrect range and filename

Hana - Network Utility v1.5.0

Hana - Network Utility v1.5.0

What's new in this release

Persistent module state Your results now survive tab switches. Ping, Multi-Ping, and Subnet Sweep all remember exactly where you left them. Multi-Ping continues monitoring in the background while you use other modules.

Real-time ping results Fixed mode ping now paints each result the moment it arrives — no more waiting for all packets to complete before seeing anything.

Accurate unreachable detection "Destination host unreachable" router replies are now correctly treated as failures across Ping, Multi-Ping, and Subnet Sweep. Loss correctly shows 100% for unreachable hosts.

First-launch disclaimer & About page New terms acceptance modal on first launch. New About tab with version info, module list, and links to documentation. Startup fix npm start now reliably opens Hana as a standalone window.
