  • Change the $domain variable to whichever domain you wish to query. Works with the majority of whois info; for some that won't, you may have to compromise: domain=google.com; for a in $(whois $domain | grep "Domain servers in listed order:" --after 3 | grep -v "Domain servers in listed order:"); do echo ">>> Nameservers for $domain from $a Note that this doesn't work as well as the first one; if they have more than 3 nameservers, it won't hit them all. As the summary states, this can be useful for making sure the whois nameservers for a domain match the nameserver records (NS records) from the nameservers themselves. Show Sample Output

    domain=google.com; for ns in $(whois $domain | awk -F: '/Name Server/{print $2}'); do echo ">>> Nameservers for $domain from $a <<<"; dig @$ns $domain ns +short; echo; done;

  • These are the parameters to ldapsearch (from ldap-utils in Ubuntu), for searching for the record for Joe Blogg's user. sAMAccountName is the LDAP field that ActiveDirectory uses to store the user name. 'DOMAIN\Joe.Bloggs' where "DOMAIN" is the the active directory domain. Othewise you could use "CN=Joe.Bloggs,DC=example,DC=com" instead of "DOMAIN\Joe.Bloggs" Show Sample Output


    10
    ldapsearch -LLL -H ldap://activedirectory.example.com:389 -b 'dc=example,dc=com' -D 'DOMAIN\Joe.Bloggs' -w 'p@ssw0rd' '(sAMAccountName=joe.bloggs)'

What Others Think

What a fascinating command. On Fedora, whois (jwhois) doesn't need the -H parameter. I can tidy it up in a few ways: You don't need the -e option for echo. If you grep -q you don't need the subshell to hide the result. As you're only doing one thing in the 'if' statement, you can get rid of it. Also I shortened the variable name in the loop. Savings: about 25% :-) for d in $(pwgen -1A0B 6 10); do echo -n "$d.com "; whois -H $d.com | grep -q 'No match for' || echo -n "Not "; echo "Available for register"; done
