About LinuxCLI
LinuxCLI gives you a real, one-time-use Linux command line for network diagnostics and OSINT lookups — dig, whois, host, curl, openssl s_client, mtr, ping and nc — without installing anything locally.
Each session runs a single command inside an isolated, disposable Docker sandbox: no privileges, read-only filesystem, no network access outside what the tool itself needs. The sandbox is destroyed immediately after your command finishes — there is no persistent state, no shell access, and no way to chain commands together.
Only a fixed whitelist of read-only diagnostic tools is available. There is no active port scanning (nmap, masscan, etc.) — that's a deliberately different class of tool and isn't offered here.
Acceptable use policy
Use LinuxCLI only against hosts and domains you own, operate, or are otherwise authorized to test — for example your own infrastructure, or public DNS/WHOIS records.
Do not use LinuxCLI to probe, harass, or gather information about third-party systems without authorization. Requests are rate-limited per IP (and per API key, if you generate one), and abusive use may be blocked.
LinuxCLI logs a hashed identifier, the command run, and its result for abuse investigation and reliability purposes. Raw IP addresses are never stored — see the privacy notes in this policy for details.
