| # If this flag is set to “accept-new” then ssh will automatically add new host keys to the user known | |
| # hosts files, but will not permit connections to hosts with changed host keys. If this flag is set to | |
| # “no” or “off”, ssh will automatically add new host keys to the user known hosts files and allow | |
| # connections to hosts with changed hostkeys to proceed, subject to some restrictions . If this flag is | |
| # set to ask (the default), new host keys will be added to the user known host files only after the user | |

| # key has changed . The host keys of known hosts will be verified automatically in all cases. | |
