Terms of Use

Agreement

These Terms of Use govern access to Putty.info. By using the site you agree to these terms. If you do not agree, do not use the site. Educational content is provided to help you understand PuTTY and SSH; you remain solely responsible for commands you run, keys you generate, and systems you administer.

Not the official PuTTY project

Putty.info is not the official PuTTY website, not an authorized support vendor, and not a reseller of PuTTY. Trademarks and software names are used for identification and education. Obtain PuTTY only from official project hosts such as the official latest download page. We never host MSI/EXE packages on putty.info.

Site content license and acceptable use

Unless otherwise noted, original text and graphics on Putty.info are produced for this site. You may link to our pages. You may not scrape the site in a way that degrades service, attempt to bypass security controls, submit malware, harvest emails, impersonate Putty.info, or use our materials to build phishing kits that impersonate PuTTY downloads.

• Do not submit passwords, private keys, or confidential production data through forms or tools.
• Do not attempt to probe or attack this site or other visitors.
• Do not misrepresent our guides as official PuTTY documentation.
• Do not hotlink our assets in a way that implies sponsorship by the official project.

Disclaimer of warranties

Content is provided “as is” and “as available” without warranties of any kind, whether express or implied, including merchantability, fitness for a particular purpose, and non-infringement. SSH and systems administration carry inherent risk. Test changes on non-production systems. Verify critical steps against the official PuTTY documentation and your organization’s policies.

Limitation of liability

To the fullest extent permitted by law, Putty.info and its operators are not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, data, goodwill, or business interruption arising from your use of the site or reliance on its content. Some jurisdictions do not allow certain limitations; in those cases our liability is limited to the maximum extent permitted.

Indemnity

You agree to indemnify and hold harmless Putty.info operators from claims arising out of your misuse of the site, your violation of these terms, or your administration of third-party systems based on information you read here.

Governing topics and changes

These terms are informational site rules and not personalized legal advice. We may update them by posting a revised version with an updated reviewed date. Continued use after changes constitutes acceptance where permitted by law. Related policies: Privacy, Cookies, Copyright, Editorial.

Field notes and runbook extras

Additional operational depth for Terms of Use (path /terms/): treat every change to authentication, forwarding, or host-key storage as a reversible change under change control. Record the PuTTY version string from Help → About, the Windows build, and whether Pageant was running. Those three facts explain a surprising fraction of “it works on my laptop” discrepancies.

When documenting the procedure for teammates, include: the saved session name, Host Name and Port from the Session panel, whether Connection type is SSH, the username, whether a PPK path is set under Connection → SSH → Auth, and whether agent forwarding is enabled. Explicitly state that Putty.info is an independent educational site and that binaries must be obtained from the official project download page. Link readers to safe download guidance, host key verification, and the official manual so they can cross-check labels that differ slightly across releases.

If you still need more diagnostics after following the sections above, reproduce the issue with logging enabled under Session → Logging to a local file you control, scrub secrets from the transcript, and compare against server auth logs for the same UTC timestamp. Avoid third-party “PuTTY fix” utilities. Prefer updating to the current stable release from official hosts, re-importing a known-good saved session, and testing from a second network path before declaring the workstation broken.

• Keep private keys passphrase-protected and backed up offline according to your organization's secret-handling policy.
• Prefer named saved sessions over ad-hoc connections for anything beyond a one-off debug.
• Disable unused tunnels and agent forwarding by default; enable them per session only when required.
• Schedule periodic key rotation and remove stale authorized_keys entries during access reviews.
• Teach new operators the difference between connection errors and authentication errors before giving them production bastion access.
