One ping monitor. Same experience everywhere.
A focused multi-host ping monitor for Windows and supported Linux desktops. Paste your hosts and see reachability, latency, packet loss and outages in one window—with the same menus, controls and shareable host lists on both platforms. Proprietary Freeware: free for personal, educational and internal commercial use.
PTTS Ping automatically inherits your operating system's Light/Dark appearance. Windows 10 and Windows 11 follow live Light/Dark changes without restarting. Native platform networking sits underneath the same desktop workflow.
No account. No server. No database. No subscription. No monitoring agent. No cloud service is required for monitoring. Just run PTTS Ping.
Save a UTF-8 host list on Windows and load it on Linux: same format, same workflow. Help → Check for Updates checks public releases only when you ask. Downloads open in your browser; nothing is silently downloaded or installed.
File provides Load List (Ctrl+O), Save List (Ctrl+S), and Exit (Ctrl+Q). The existing buttons remain. Options provides Clear Counters and Reset to Defaults. Reset asks first, stops monitoring, clears current/remembered hosts, and restores 5 sec / 5 min / 20%. It preserves window/column/splitter state and saved list files. Help provides manual Check for Updates and About PTTS Ping.
- Continuous monitoring of IP addresses and hostnames, with latency and success/failure/packet-loss counters. Interval changes take effect immediately; unfinished batches prevent overlapping cycles. Large lists use adaptive rolling monitoring and update progressively.
- All / Responded views make large target sets easier to work with. Responded retains hosts that have replied at least once, including hosts that later go DOWN, across monitoring restarts while the same host list is retained.
- Last Failure records the latest applied failed result in local time.
- Failure Duration shows the current continuous outage using monotonic time; recovery clears the duration but preserves Last Failure.
- Flapping highlights unstable hosts using recent results and configurable window/threshold controls, as illustrated below.
- Clear Counters resets counters and flap history while preserving Last Failure, current status, and active outage timing. Changing Flap Window restarts only flap history; changing the threshold reevaluates retained samples immediately.
- Reverse DNS enriches unnamed IP entries independently of ping workers. Windows uses asynchronous PTR requests with a two-second application deadline; Linux keeps its platform-native resolver path.
- Numeric IP sorting, read-only results, user-resizable columns, horizontal scrolling, and a draggable vertical host-input/results splitter.
- Save List / Load List use UTF-8; saves replace files atomically. The last host list and window size/state, splitter allocation, and column widths are remembered. Under Wayland, exact top-level window placement may remain controlled by the compositor/window manager.
Each new Start begins a fresh monitoring session. Stopped or superseded results
cannot update the new session. Unknown latency is displayed as --.
Flapping requires both successful and failed samples, at least two UP/DOWN transitions, and a failure percentage at or above the selected threshold within the rolling Flap Window. YES appears yellow with black text and can occur while the host is currently UP or DOWN. Expired history clears the indication automatically without requiring a new ping.

Interval controls how often monitoring runs; 5 seconds is the recommended default for normal monitoring. Shorter intervals increase monitoring frequency and CPU usage. Flap Window selects how far back results are retained (default 5 minutes, range 1–60). Failure threshold sets the minimum failed-ping percentage needed for flapping (default 20%, range 1–100); the transition and mixed-result requirements still apply.

Enter one target or named entry per line:
192.0.2.10
example.com
server01<TAB>198.51.100.20
server01,198.51.100.20
server01 198.51.100.20
192.168.1.0/24
203.0.113.10-203.0.113.20
# Full-line comments are ignored
Replace <TAB> with an actual tab. A tab/comma row must have exactly two fields;
its target must be nonempty. An empty name uses the target as its display name.
Whitespace-separated rows accept a single target or Name Target.
IPv4 CIDR ranges and explicit ranges allow at most 4096 addresses. Full-line
# comments are ignored. Explicit ranges allow whitespace around -.
Reversed or malformed numeric ranges are rejected. Ordinary hyphenated hostnames
remain supported. Malformed input is rejected before monitoring starts, with a
line-numbered warning. Option-like targets beginning with - are rejected.
Windows 10 Pro 22H2 x64, Windows 11 x64 and Kubuntu 26.04 passed real-desktop install/upgrade acceptance. A single Windows x64 installer supports Windows 10 1809+ and Windows 11; real-desktop Windows 10 qualification was performed on 22H2. Package validation covers Ubuntu 24.04/26.04, Fedora 43/44, Rocky Linux and AlmaLinux 9/10, and openSUSE Leap 16.0. Those distro-matrix results are clean container validation, not additional desktop claims. Debian and RHEL are not validated targets.
Settings are separate from the installed package and survive upgrades/uninstall:
- Windows:
%LOCALAPPDATA%\PTTS Ping - Linux:
~/.config/ptts-ping
Monitoring preferences live in settings.ini, remembered UTF-8 hosts in
last_hosts.txt, and machine/display-specific window state in ui.ini.
User-created host-list files stay wherever you saved them.
Remove the Windows application through Installed Apps. On Ubuntu use your
software installer or sudo apt remove ptts-ping; on Fedora/Rocky/Alma use
sudo dnf remove ptts-ping; on Leap use sudo zypper remove ptts-ping.
Uninstall leaves your user settings intact.
For bugs, installation problems, questions or requests, open an issue. Include the PTTS Ping version, operating system/version, expected and actual behavior, and steps to reproduce. Do not post private host lists or credentials.
