Noninteractive mode is useful when only a single piece of data needs to be returned. The syntax for noninteractive mode is: nslookup [-option] [hostname] [server] To start Nslookup.exe in interactive mode, simply type "nslookup" at the command prompt: C:\> nslookup Default Server: nameserver1.domain.com Address: 10.0.0.1 > Typing "help" or "?" at the command prompt will generate a list of available commands. Anything typed at the command prompt that is not recognized as a valid command is assumed to be a host name and an attempt is made to resolve it using the default server. To interrupt interactive commands, press CTRL+C. To exit interactive mode and return to the command prompt, type exit at the command prompt. The following is the help output and contains the complete list of options: Commands: (identifiers are shown in uppercase, [] means optional) NAME - print info about the host/domain NAME using default server NAME1 NAME2 - as above, but use NAME2 as server help or ? - print info on common commands set OPTION - set an option all - print options, current server and host [no]debug - print debugging information [no]d2 - print exhaustive debugging information [no]defname - append domain name to each query [no]recurse - ask for recursive answer to query [no]search - use domain search list [no]vc - always use a virtual circuit domain=NAME - set default domain name to NAME srchlist=N1[/N2/.../N6] - set domain to N1 and search list to N1, N2, and so on root=NAME - set root server to NAME retry=X - set number of retries to X timeout=X - set initial time-out interval to X seconds type=X - set query type (for example, A, ANY, CNAME, MX, NS, PTR, SOA, SRV) querytype=X - same as type class=X - set query class (for example, IN (Internet), ANY) [no]msxfr - use MS fast zone transfer ixfrver=X - current version to use in IXFR transfer request server NAME - set default server to NAME, using current default server lserver NAME - set default server to NAME, using initial server finger [USER] - finger the optional NAME at the current default host root - set current default server to the root ls [opt] DOMAIN [> FILE] - list addresses in DOMAIN (optional: output to FILE) -a - list canonical names and aliases -d - list all records -t TYPE - list records of the given type (for example, A, CNAME, MX, NS, PTR, and so on) view FILE - sort an 'ls' output file and view it with pg exit - exit the program A number of different options can be set in Nslookup.exe by running the set command at the command prompt. A complete listing of these options is obtained by typing set all. See above, under the set command for a printout of the available options. Looking up Different Data Types To look up different data types within the domain name space, use the set type or set q[uerytype] command at the command prompt. For example, to query for the mail exchanger data, type the following: C:\> nslookup Default Server: ns1.domain.com Address: 10.0.0.1 > set q=mx > mailhost Server: ns1.domain.com Address: 10.0.0.1 mailhost.domain.com MX preference = 0, mail exchanger = mailhost.domain.com mailhost.domain.com internet address = 10.0.0.5 > The first time a query is made for a remote name, the answer is authoritative, but subsequent queries are nonauthoritative. The first time a remote host is queried, the local DNS server contacts the DNS server that is authoritative for that domain. The local DNS server will then cache that information, so that subsequent queries are answered nonauthoritatively out of the local server's cache. Querying Directly from Another Name Server To query another name server directly, use the server or lserver commands to switch to that name server. The lserver command uses the local server to get the address of the server to switch to, while the server command uses the current default server to get the address. Example: C:\> nslookup Default Server: nameserver1.domain.com Address: 10.0.0.1 > server 10.0.0.2 Default Server: nameserver2.domain.com Address: 10.0.0.2 > Using Nslookup.exe to Transfer Entire Zone Nslookup can be used to transfer an entire zone by using the ls command. This is useful to see all the hosts within a remote domain. The syntax for the ls command is: ls [- a | d | t type] domain [> filename] Using ls with no arguments will return a list of all address and name server data. The -a switch will return alias and canonical names, -d will return all data, and -t will filter by type. Example: >ls domain.com [nameserver1.domain.com] nameserver1.domain.com. NS server = ns1.domain.com nameserver2.domain.com NS server = ns2.domain.com nameserver1 A 10.0.0.1 nameserver2 A 10.0.0.2 > Zone transfers can be blocked at the DNS server so that only authorized addresses or networks can perform this function. The following error will be returned if zone security has been set: net send net send [computer] [message] net send [computer name or ip address] message net use - map drive net use p: \\servername\sharename /persistent:yes net use allows you to map a drive Save the following text bellow to a .bat file and execute it @echo off net use p: \\servername\sharename /persistent:yes net stop - stop a windows service net stop [NameofService] net stop "[service name]" net start - start a service net start [NameofService] start service - start a service Email vbs Dim objMail, strSenderEmail, strDestinationEmail, strEmailSubject, strEmailBodyMsg strSenderEmail = "username@domain.com" strDestinationEmail = "username@domain.com" strEmailSubject = "Email Subject " & Date() strEmailBodyMsg = "This is the body of the Message " & Date() Set objMail = CreateObject("CDONTS.NewMail") objMail.From = strSenderEmail objMail.To = strDestinationEmail objMail.Subject = strEmailSubject objMail.Body = strEmailBodyMsg objMail.Send 'Set Objects and Variables to Nothing set objMail = nothing strSenderEmail = "" strDestinationEmail = "" strEmailSubject = "" strEmailBodyMsg = "" 'Test SMTP service is working (CDONTS) Dim objMail, strSenderEmail, strDestinationEmail, strEmailSubject, strEmailBodyMsg strSenderEmail = "username@domain.com" strDestinationEmail = "username@domain.com" strEmailSubject = "Email Subject " & Date() strEmailBodyMsg = "This is the body of the Message " & Date() Set objMail = CreateObject("CDONTS.NewMail") objMail.From = strSenderEmail objMail.To = strDestinationEmail objMail.Subject = strEmailSubject objMail.Body = strEmailBodyMsg objMail.Send 'Set Objects and Variables to Nothing set objMail = nothing strSenderEmail = "" strDestinationEmail = "" strEmailSubject = "" strEmailBodyMsg = ""
