SSH Config and Connection Command
Generate an SSH Host block with a keepalive interval, optional ProxyJump and a matching connection command locally.
About this ssh config and connection command
Generate an SSH Host block with a keepalive interval, optional ProxyJump and a matching connection command locally Performs protocol inspection, IP calculation, and network analysis client-side without sending probes or exposing network topology.
Protocol mechanics & network logic
Enter a JSON object with alias, hostname, user, port, identityFile and optional proxyJump/forwardAgent. Choose the keepalive interval, generate, then copy the Host block or connection command. The original five-directive generator stays below.
Worked network diagnostic scenario
Scenario: Generate a five-line SSH config fragment without connecting.
Sample input:
Processing: Validate tokens and format the five configured lines. With alias prod and interval 60, the block ends in ServerAliveInterval 60 and the command is ssh prod. An optional ProxyJump bastion.example.com line is preserved.
Illustrative output:
Addressing limits & protocol boundaries
This form accepts one alias starting with an ASCII letter or digit, then letters, digits, dot, underscore or hyphen; no wildcard or multiple aliases. ServerAliveInterval is 0–86400 whole seconds; 0 disables these messages, 60 is this form’s sample, not the OpenSSH default. Keepalives do not guarantee a connection stays alive. The original generator still rejects control characters and ports outside 1–65535. No SSH process runs and no configuration file, key or remote account is accessed.
Addressing calculations and subnet models in SSH Config and Connection Command follow IETF RFC definitions. Ensure subnet masks and CIDR prefixes match your network topology.
Offline network inspection boundary
Address parsing and CIDR calculations in SSH Config and Connection Command run entirely client-side without probing external IP networks or transmitting routing data.

Frequently asked questions
What configuration text does it generate?+
Original shorthand helper: Builds Host, HostName, User, Port and IdentityFile lines from JSON; optional ProxyJump and ForwardAgent yes are appended. It only returns text and never connects.
Which controls and limits apply?+
Original shorthand helper: The page has one JSON input, Run locally and Load sample. Port must be an integer 1 through 65535; blank values use defaults. It does not test DNS, credentials, keys, reachability or server policy.
Which token boundaries apply?+
Original shorthand helper: Tokens reject line breaks and control characters. proxyJump is emitted only when supplied and forwardAgent only when true. Generated text is a starting fragment, not a verified SSH configuration. Review and paste the copied Host block into your own ~/.ssh/config, before broader defaults when appropriate; OpenSSH generally uses the first obtained option value. Run the command yourself only after installing the block. The browser does not append to that file.
What result does the worked example produce?+
Original shorthand helper: In the worked example, the tool matched the independent prod/example.com/deploy/22 vector. That proves this local five-line output only.
