It offers\nboth a library and a command-line tool to scan specific domains for\n(currently) one layer of subdomains. The scan is dictionary-based and\nit will attempt to avoid superfluous queries by basing subsequent\nqueries off of previously discovered records.\n\nfess_up's scanning wordlist is based on files installed in the\nfess_up/dnsnames/ directory. To expand this list, either edit\n`default.txt` or add another .txt file to the directory and it\nwill be automatically loaded.\n\nCommand-line tool\n-------\n\nTo scan a domain using the `fess_up.py` (installed as\n`fess_up` when using the Debian package) command line tool, simply\nprovide the domain as an argument:\n\n```\nfess_up nosmo.me\nnosmo.me\n{'@': {'A': ['92.51.245.61'],\n        'MX': [('nosmo.me.', 10)],\n        'TXT': ['v=spf1 mx -all']},\n 'www': {'A': ['92.51.245.61'],\n        'CNAME': ['nosmo.me.'],\n        'MX': [('nosmo.me.', 10)],\n        'TXT': ['v=spf1 mx -all']}}\n```\n`fess_up` can also output in a bind-like fashion when using the -B flag.\n\n```\nfess_up.py nosmo.me -B\nnosmo.me\n@       IN      A       92.51.245.61\n@       IN      TXT     v=spf1 mx -all\n@       IN      MX      10      nosmo.me.\nwww     IN      A       92.51.245.61\nwww     IN      CNAME   nosmo.me.\nwww     IN      MX      10      nosmo.me.\nwww     IN      TXT     v=spf1 mx -all\n```\n\nLibrary\n--------\n\n`fess_up`'s domain scan can be used as a library:\n\n```\n\u003e\u003e\u003e from fess_up import dnsnames, DomainScan\n\u003e\u003e\u003e domain_scanner = DomainScan(\"nosmo.me\", dnsnames.dnsnames)\n\u003e\u003e\u003e domain_scanner.runScan()\n\u003e\u003e\u003e dict(domain_scanner.data)\n{'www': {'A': ['92.51.245.61'], 'CNAME': ['nosmo.me.'], 'MX': [('nosmo.me.', 10)], 'TXT': ['v=spf1 mx -all']}, None: {'A': ['92.51.245.61'], 'TXT': ['v=spf1 mx -all'], 'MX': [('nosmo.me.', 10)]}}\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnosmo%2Ffess_up","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnosmo%2Ffess_up","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnosmo%2Ffess_up/lists"}
