Chapter I - Introduction Introductory paragraphs Chapter I begins with a few short introductory paragraphs a couple of pages at most.
Communications Commands Certain of the following commands find use in network data transfer and analysis, as well as in chasing spammers. With the -h option, ipcalc does a reverse DNS lookup, finding the name of the host server from the IP address.
This is essentially equivalent to ipcalc -h or dig -x. The command may be run either interactively or noninteractively, i. The nslookup command has allegedly been "deprecated," but it is still useful. Similar to nslookup, dig does an Internet name server lookup on a host.
May be run from the command-line or from within a script. Compare the output of dig -x with ipcalc -h and nslookup.
Wed Jun 26 Finding out where to report a spammer! Look up abuse contact to report a spammer. Check for command-line arg. The following also works: Can even lookup multiple spammers with this, i.
Analyzing a spam domain! Uses IFS to parse strings by assignment into arrays. And even does something useful: For a much more elaborate version of the above script, see Example A The remote host may be specified by an IP address.
The output of this command may be filtered by grep or sed in a pipe. This is a diagnostic tool for testing network connections, and it should be used with caution. This can be tested for in a script.
The -h option permits specifying which particular whois server to query. See Example and Example Out of security considerations, many networks disable finger and its associated daemon.
This command seems to be missing from newer Linux distros. Remote Host Access sx, rx The sx and rx command set serves to transfer files to and from a remote host using the xmodem protocol. These are generally part of a communications package, such as minicom. Zmodem has certain advantages over xmodem, such as faster transmission rate and resumption of interrupted file transfers.
Like sx and rx, these are generally part of a communications package.
An ftp session can be automated in a script see Example and Example A This is a communications package for transferring files between UNIX servers. A shell script is an effective way to handle a uucp command sequence. Since the advent of the Internet and e-mail, uucp seems to have faded into obscurity, but it still exists and remains perfectly workable in situations where an Internet connection is not available or appropriate.
The advantage of uucp is that it is fault-tolerant, so even if there is a service interruption the copy operation will resume where it left off when the connection is restored. Execute a command on a remote system. This command is part of the uucp package. Call Up a remote system and connect as a simple terminal.
It is a sort of dumbed-down version of telnet. The telnet protocol contains security holes and should therefore probably be avoided. Its use within a shell script is not recommended. It works well in a script. This works with ftp servers and many HTTP sites.Chapter 1 - Getting Started Getting to DOS.
To run QBASIC we need to get to DOS. If you are using Windows 7, you might need to use dosbox. See Appendix C for details.. If you are using Windows XP, it is called the "Command Prompt" and you can get to it by clicking on Start, then All Programs, then Accessories, then Command Prompt.
