Features

Everything you need,
nothing you don't

Built for network and security engineers who live in the terminal.

Terminal Sessions

SSH, Serial/COM, and Telnet with full xterm-256colour rendering, scrollback history, split-view compare, and automatic session logging.

  • SSH host key verification (TOFU) with known-hosts store
  • Keyboard-interactive & password SSH auth
  • Per-session font, size & colour customisation
  • Side-by-side session compare (horizontal & vertical)

Syslog Monitor

Built-in syslog server (UDP & TCP) with five basic threat detection rules and a SOC-style dashboard. Designed for testing and lab environments — use a dedicated SIEM for production.

Bandwidth Monitor

iPerf3-based throughput testing with live speed chart. Built-in local iPerf3 server mode — no external tool needed.

TFTP & FTP Servers

One-click TFTP and FTP servers for firmware pushes and config backups. FTP uses PBKDF2-hashed credentials.

Network Tools

Ping, Traceroute, DNS Lookup, WHOIS IP & Domain, Subnet Calculator, Port Scanner, IP Scanner — right-click any output to copy or clear.

Security Built In

App login with PBKDF2-SHA256, AES-256-GCM session store, inactivity auto-lock, and SSH host key verification (TOFU).

SNMP Monitor

Walk, Get, Set and Trap receiver for SNMP v1, v2c, and v3. Device inventory, MIB browsing, and live trap feed.

Syslog Monitor

Basic threat detection
for testing & labs

V-Terminal includes five lightweight detection rules to help you spot common threats during testing and lab work. For production environments, a dedicated full-featured SIEM is recommended.

BRUTE FORCE Auth failures within a sliding window → T1110
PORT SCAN Unique denied ports per source IP → T1046
MALICIOUS IP Real-time IP reputation lookup → T1071
ANOMALY Welford online Z-score detection → T1562
SUSPICIOUS Exploit / injection keyword patterns → T1059

FAQ

Common questions

Yes — completely free for personal and commercial use under the MIT license. No account required, no telemetry, no feature gating, no trial period.
No. Both the Installer and Portable editions are fully self-contained Windows executables. Python, all libraries, and the Tkinter runtime are bundled inside the .exe — nothing else to install.
Installer (.exe): Runs the setup wizard, adds a Start Menu shortcut and an entry in Add/Remove Programs. Recommended for a permanent workstation install.

Portable (ZIP): Extract and run V-Terminal.exe directly — no registry changes, no admin rights required. Ideal for USB drives, shared lab PCs, or quick testing.
This is a known false positive with PyInstaller-packed executables. The bundler compresses Python bytecode and native DLLs into a single exe — a technique that some heuristic scanners flag. V-Terminal has no malicious code. If needed, add an exclusion for the V-Terminal folder in your AV settings.
Everything stays 100% local on your machine. Session profiles are encrypted with AES-256-GCM and stored in a data\ folder next to V-Terminal.exe. Session logs go to data\session_logs\. Nothing is sent to any server.
No — the built-in detection is intended for testing, labs, and home labs only. All five rules run in memory with no persistent storage or correlation engine, so they are not a substitute for a dedicated production SIEM. For production environments, forward your syslogs to a full SIEM (Splunk, Graylog, Wazuh, etc.) and use V-Terminal as the collection and monitoring tool on the endpoint.
Yes. Open Settings → Sessions to save any connection as a named profile. Profiles are encrypted with AES-256-GCM and stored locally — your credentials are never stored in plain text. Saved sessions appear in the sidebar for one-click connect.
