Please note that Telnet sessions pass information in plain text and are therefore not considered to be secure. For secure, encrypted sessions we recommend using the SSH protocol. Please connect to your server with telnet or SSH. You can use Windows 2000/98/ME telnet program simply by clicking "START" -à "Run" and enter telnet domain.com. Once a successful connection is established, youll receive a login prompt. Enter the username for your server and press Enter. Next, youll be asked for a password. Type in the password that you received and press Enter. After logging in, your screen should look something like the following: Welcome. login: dyntex
machine: cassiopeia.dyntex.net Please abide by the server policies listed below. The following items
or activities are not allowed on this server. ****Thank you!****
Su And hit <enter>. It will prompt you for a password. Enter the root password sent to you in your login emails. Your screen should now look like this: cassiopeia:/home2/dyntex$ su Password: cassiopeia:/home2/dyntex# The # denotes you are ROOT. If at any point you get confused on what username you are logged in as simply type: whoami and unix will display your username. Your screen will look like this if you run whoami: cassiopeia:/home2/dyntex# whoami root cassiopeia:/home2/dyntex
Your Servers File System Structure Your server runs on UNIX and is very similar to the directory structure used by DOS. The directory tree starts at the root, which is the lowest possible level in the directory tree. From the root level, the file structure branches out into sub-sections or what is know as "directories." A directory that contains another directory is called a parent directory. Directories can branch out into subdirectories, which in turn can branch out and contain other subdirectories, and so on. The relationship between the root and any directory within the system is called a path. Paths are displayed with an initial slash (/) to denote the root, and subsequent directories are separated by additional slashes. If you ever get lost and do not remember where you are in the directory tree, you can type: pwd and UNIX will display the current directory. Your screen will look like this if you run the pwd command: cassiopeia:/home2/dyntex# pwd /home2/dyntex cassiopeia:/home2/dyntex#
When you first login to your server you start out in your home directory. This is the directory on the system that contains all the files and subdirectories pertaining to you and your server.The path to your home directory is: /home/username Note that username is the same username you use to login to the server. To understand the path to your home directory, realize that by starting at the root, then branching off into the directory called "home" then branching off into the directory called "username," you arrive at your very own home directory. In your home directory, you "own," or have permission to access, any of the directories and files contained in or below the directory, with the exception of a few system files that you do not have the ability to edit or delete.
man: A type of UNIX help system that displays a manual page about a specified command. pwd: Short for Print Working Directory. Displays the path to the current directory. ls (list): Displays a list of the files and directories in the current directory. ll (long list): Displays a "long listing" of files, directories, permissions and file size in the current directory. Similar to the DOS command DIR. grep: Searches documents or directories for a specific word, phrase, or file. cd (change directory): Used to move to a different directory. If no directory is specified, it will take you to your home directory. mkdir (make directory): Creates a new directory. mv: Moves a file into another directory, or renames a file by "moving" an existing file to a new file with a new name. rm (remove): Removes a file or directory. cp (copy): Copies a file or directory. touch: Creates a new, empty file or updates the date that an existing file was last modified. more: Displays the contents of a text file. If the contents of the file are larger than your screen, it will wait for you to ask for more by pressing the space bar. pico: Starts the PICO online text editor. pine: Starts the PINE email program.
--I am lost! What do I do? This section introduces you to some helpful commands when discovering for the first time you have absolutely no idea where you are:
Use the pwd command to display the full path of the directory you are currently in.
Use the ls command to view the files and directories contained within your current directory. The ls command will output like this: 19t.gif hostsentry-0.02/ 1t.gif hostsentry-0_02_tar 21t.gif htac 23t.gif htsdata/ 25t.gif index.html
The l command displays a "long list" of files and subdirectories within the current directory, including file permissions, file ownership, file sizes (in bytes), and the date each file or directory was created or last modified. l is technically not a command, but an alias to ls al. The l "command" is similar to the DOS command DIR. If you run the l command your screen will look like this: drwxr-xr-x 3 dyntex dyntexgr 124 Jan 1 2000 .htsdata -rw-r--r-- 1 dyntex dyntexgr 184320 Jan 1 2000 hostsentry-0_02_tar -rw-r--r-- 1 dyntex dyntexgr 165 Jul 12 2000 htac drwxr-xr-x 3 dyntex dyntexgr 1024 Jan 1 2000 htsdata -rw-r--r-- 1 dyntex dyntexgr 13253 Jul 12 2000 index.html -rw-r--r-- 1 dyntex dyntexgr 1499 Jul 9 2000 index.html.bak Notice that in this view of the same directory, files that start with a dot (.) also appear. These files are typically necessary system files and they are not shown with the ls command. Take a look at the first (far-left) column of this output. Note that each line begins with one of 3 characters: a d, an l, or a dash (-). A dash denotes a file; d stands for directory; and l refers to link. --How do I create a file or directory?
You can create your own directories with the mkdir command. Example: At the command prompt, type:
and hit <enter> You have just created a directory called "testing"
To work within a directory, you must first move into that directory using the cd command. Example: To check out the "testing" directory you just created, type:
and hit <enter> You are now in the /testing directory. To verify this, type: pwd Enter The full path is displayed as /home/username/testing Here are some other features of the cd command worth noting: If you dont specify a directory you will automatically be taken to your home directory. You can perform this by just typing: cd and hit <enter> You are now automatically taken back to your home directory (home/username).
Similar to the mkdir command, which is used to create directories, the touch command is used to create empty files. This command also can be used to update the date that a file was last modified. Example: Create an empty file called 1234 touch 1234 and hit <enter> Note that the 0
bytes file 1234 has been added to the directory listing.
The grep command can be used to search text files for occurrences of a word or phrase. Example: To search your /home/www/dyntex/index.html file for the word hosting, type: grep hosting /home/www/dyntex/index.html and hit <enter> The output displays all of the lines that contain the word hosting within the file.
To add text to a file, you can use pico, an online editor. Pico is a simple text editor that comes pre-bundled with UNIX and is very easy to use. Its menu based and similar to the old DOS versions of MS Word. Example: you want to create a file called index.html. You would type: pico index.html and hit <enter> Pico will automatically open and create an empty file called index.html. Whatever text you add to the file will be later saved. Your screen should look like this:
Because the file is empty, the editing screen will look blank. Now type some text to make it come alive:
And hit<enter> To save the new contents of this file, press Ctrl+X. Pico will ask if you would like to save the contents of the file. Press Y to do so. Finally, pico will ask you what to name the saved file (File Name to write). By default, pico suggests you keep the same filename, so simply press Enter to accept. Now if you go to your web browser and open it up to http://www.domain.com/index.html you will see: I am testing PICO. What will this do? While using pico, there are several key combinations that will help you view or edit a file. Below find the most common used commands or key strokes:
Ctrl+Y View previous page Ctrl+V View next page
The more command displays the contents of a text file. If the contents of the file are larger than your screen, you "ask for more" by pressing the space bar when you are ready, or quit by pressing Ctrl+C. Example: Use the more command to verify that the new text you entered with pico is now saved inside your "hello" file:
And hit<enter> The text you entered with Pico should appear:
The cp command is used to copy one file to another. The format of the cp command is cp source target where the source is the original file and the target is the name of the new file. Example: Make a copy of your hello file and name the copy "hello2." cp index.html index-old.html And hit<enter> To verify that the file was copied successfully, type: ls And hit<enter> There is now a index-old.html file in addition to the index.html file. To verify that the contents of the newly created or copied file index-old.html you can type: more index.html And hit<enter> Again, the same input appears:
The mv command can be used to either move a file into another directory, or to rename a file (by "moving" an existing file to a new file with a new name). Example 1: To rename the index.html file as "index-1234.html" type: mv index.html index-1234.html And hit<enter> Now the file will be renamed index-1234.html and index.html will be gone. Example 2: Create a new directory called dir1234 and move the index-1234.html file into it: mkdir dir1234 And hit<enter> You have now just created a new directory called dir1234. Now lets move index-1234.html into it: mv index-1234.html dir1234 The index-1234.html file is now in the directory dir1234. QUIZ: What is the full path to the file index-1234.html in directory dir1234? Answer: /home/username/dir124/index-1234.html
You can remove files with the rm command. Be very careful using this command. Once you remove a file its gone forever. Example: Lets remove the file called index-1234.html in the directory dir1234. Make sure you are still in this directory. If you are unsure type pwd and you should see: /home/username/dir1234 rm index-1234.html And hit<enter>
Using the R option with the rm command allows you to delete directories as well as files. Be very careful when using the -R option with the rm command. Used incorrectly, this command can cause a lot of damage as it removes every file in the directory in one clean swoop. Example 1: Delete the dir1234 To do this you need to be one directory higher, do if you are in dir1234 you need to type: cd .. And hit<enter> The .. directs the operating system to take you up 1 directory level or back to /home/username in this case. To verify you have done this correctly type pwd and you should see: /home/username One note on this, the rm command alone will NOT remove a directory. To prove this, type:
And hit<enter> The following error message appears: rm: dir1234: is a directory To prevent you from deleting an entire directory by accident, the rm command requires an additional flag, or command line option, to verify that you really want to remove the directory. Now, try removing the dir1234 directory using the R (recursive)flag:
And hit<enter> In the preceding command line, the R option tells the rm command to recursein other words, to not only remove the specified directory, but to also remove all files and/or subdirectories that the dir1234 directory contains. Youll now be asked to confirm that you really want to delete the directory and each file contained within it. Press Y, Enter to confirm.
Useful Directories / Is the base or
root directory of the entire file system. /ftp/logs This
directory houses all of the FTP transfer logs. /home/access-log: Contains records of all the Web activity that occurs on your server. /home/username/www/cgi-bin
Contains executable binary files and script files that can interact
with Web visitors through their Web browser. These programs are commonly
referred to as CGI programs. CGI stands for "Common Gateway Interface." /etc/passwd
This file contains all of the users that are setup to access the server. dhudson@king.com webmaster
test@king.com king993@aol.com This means that any email that comes to test@king.com will automatically be forwarded on to king993@aol.com The simplest way to distinguish /etc/da and /etc/da2 is that they are both mail forwarding configuration files but /etc/da2 forwards off the server while /etc/da keeps mail on the server. /etc/domains This file contains a list of all of the virtual domains on the server, the default username and the group name for that domain. If you edit this file your screen will look like this: king.com 63.249.159.44 kinggrp
king.com 63.249.159.44 fakeking.com This shows that king.com which is located at the IP address 63.249.159.44 on this local server also has a aliased domain fakeking.com which will bring users to the same space. Simply put, in a web browser if someone types king.com or fakeking.com they will pull up the files located at king.com on this server. /etc/.ipaliases.data This file will show you every IP address bound to your server.
Other important files and their directories: /etc/sendmail.cw: Contains a list of domain names that you wish to be able to provide email service for on your server. /etc/sendmail.cf: A very important file that allows your server to handle email. Do not edit unless you are extremely versed in UNIX. All of the automated software on your server can update and edit this as needed for you. /etc/hosts: This file shows you every domain on the server and the IP address assigned to it. It will also show you which IPs are bound to your server to use for future addition of virtual domains. /usr/bin: This directory contains many of the commands that you use on your server. Because of the way your server is configured, these commands are accessible from any directory. For example, the files ls and pwd are actually stored in this directory, but you can use them from any directory on your server. You should never need to change any of the files in this directory, and it's a very good idea not to try. /usr/log: This directory contains an important file, called xferlog and httpd. The xferlog file contains a record of all the FTP activity that takes place on your server and the httpd log records every web hit. /var/spool: This directory contains a subdirectory called mqueue, which stores any mail that is waiting to be sent from your server. Because mail is usually sent immediately, this directory will be empty most of the time. However, if there is a temporary delivery problem, mail may queue up here for later delivery. /ftp: This directory contains files for email and FTP users that you add to your VServer. In some cases, a directory will be created in here with the user's name and will act as that user's home directory. /var/spool/mail: This directory contains stored email messages for your Administrative Email account, and for any POP users you have added to your server. /home/www/httpd.conf: The main configuration file for your servers Web service. This is the configuration file that is modified most often. You can edit it to configure your servers Virtual Hosting capabilities, to modify the way your log files are managed, and to configure many other advanced features. This file is very complicated to edit. Please use the proprietary domain provisioning tool installed on your server by typing account at any root level prompt. The /home/www/conf/httpd.conf file is the main configuration file for your Web service. It contains directives relating to the operation of the server as a whole, and is therefore the file you are most likely to make changes to. Some of the more useful or important directives in your httpd.conf file are: HostnameLookups: This directive turns on or off reverse DNS lookups in your log files. When off, the Web server responds more quickly. When on, the server performs DNS lookups every time a user hits the page. Although it can provide useful information, the HostnameLookups option causes the Web server to respond more slowly. For this reason, HostnameLookups is turned off by default. ServerName: Specifies the name of your server. The server name MUST be a valid domain name that was assigned to you. By default this will end in .dyntex.net which is the network your server is housed on. ServerAdmin: This directive denotes the email address that a visitor should contact in case of server problems. The address is displayed through the browser in some error messages and is also available in CGI scripts as a variable called SERVER_ADMIN. By default, the ServerAdmin is set as the webmaster@yourdomain.com, but can be any valid email address. ErrorLog: Specifies the location of the file where you want to log your Web server errors. It is useful for debugging CGI programs and finding broken links on your Web site. By default, this directive is set to logs/error_log. TransferLog: Specifies the location of the file where you want to log information about requests (often called "hits") that are made to your Web service. By default, this directive is set to logs/access_log. AgentLog: Specifies the location to log information about the types of Web browsers that are being used to visit your site. By default, this directive is set to logs/agent_log RefererLog: Specifies the location to log information about where your Web visitors are being "referred" fromin other words, where they were before they came to your Web site. The misspelling of the word referer is intentional for historical reasons. By default, this directive is set to logs/referer_log. <VirtualHost></VirtualHost>: This directive allows you to host additional domains on your server. Directives that are placed between <VirtualHost> and </VirtualHost> apply only to that specific virtual host. By default, there should be a <VirtualHost> entry present for your main domain name. Most directives can be applied to a <VirtualHost> entry. /home/www/srm.conf: Contains important configuration data concerning Web directories and file names. One part of this file that you may want to modify is a section that allows you to specify custom error pages for you server Web service. Please use the proprietary domain provisioning tool installed on your server by typing account at any root level prompt. The /home/www/conf/srm.conf file contains directives that relate to names and resources in the file systemfile paths, directory indexes, aliases, and so forth.
DocumentRoot: Specifies the directory where your HTML documents are to reside. Your Web service will not function without this directive. By default, this is set to /www DirectoryIndex: Specifies the name of the file or files to look for as the default home page. If the file named here is not present, an "index" of the directory will be created if the Options directive that pertains to that directory allows indexing. By default, this directive is set to allow the follwing files to execute by default if someone just types http://domain.com in a browser:
UserDir: This directive is used to enable to disable the use of user directories inside your Web site URLs. If you define a name here, and FTP users that you have added to the /home/username directory tree can serve Web documents from your Web site by creating a directory by that name in their home directory and using username in URLs. By default, this option is off. Typically, the directive is set to public_html to enable this service. AccessFileName: Specifies the name of the file to look for in each directory for access control information. The contents of the file named here can override the global access control settings that are contained in /home/www/conf/access.conf if the AllowOverride directive that pertains to that directory allows overrides. By default, this is set to .htaccess. Redirect: Allows you to redirect clients to a different area of the Web site, or even to a different Web site. AddType: Allows you to define new media types and associate them with a file extension, and optionally, an executable program such as a CGI. ErrorDocument: Allows you to specify an alternate document to display when Web server errors occur. Alias: Allows you to create directories that can contain Web-servable contents but are physically located outside of the document root. By default an alias for the icons directory that contains the images for server-generated index files is defined as: Alias /icons/ /www/icons ScriptAlias: Allows you to create directories that can contain executable programs that are available to the Web server but are physically located outside of the document root. This is used both to enable CGI-BIN capabilities on your primary Web site, and on virtual hosts when used inside <VirtualHost> directives. By default a script alias for your /home/username/www/cgi-bin directory is defined as: ScriptAlias /cgi-bin/ /www/cgi-bin/
access.conf: Defines the general access settings for your server. This file determines who is able to access your server and what visitors are able to do in certain directories. You can edit this file in order to restrict access to specific directories of your document root to specific people, groups, and passwords. Please use the proprietary domain provisioning tool installed on your server by typing account at any root level prompt. The acces.conf file divides the Web server space into several sections using <Directory></Directory> directives. Options, restrictions, and other settings pertaining to the specific sections are placed within these directives. For security reasons, the most important directive may be the AllowOverride directive. By default, the document root allows unrestricted overrides. If this is a concern to you, you should change the AllowOverride directive to None, or a combination of the following:
By default, the Options setting for main Web directories is set to allow auto-generated indexes, symbolic link navigation, and Server Side Includes. For the /home/username/www//cgi-bin directory it is set to allow CGI execution and symbolic link navigation. This directive can be set to any of the following, alone or in combination:
mime.types: Defines the media types for your server. You may edit this file to add new file types to your server as new multimedia extensions become standardized. An example of a mime.type would be this: application/commonground dp
Virtual Domain Provisioning Tools
This is a proprietary tool constructed to help you administer your server with very little knowledge of the inner-workings of UNIX. You can do pretty much anything you need to do by using the account bot. To start the account bot simply type: account and hit <enter>
There are currently 0 domains on this server. Main menu: 1. Add a new domain. 2. Add a new user. 3. Setup menu. 4. Add an Email only account(POP access). 5. Delete/modify user/domain. 6. Add members to an existing group. 7. Add/modify disk quotas. 8. Update nameserver only. 9. Add an ftp only account. 10. Realaudio. 11. Point domain A to domain B. 12. Move domain 13. Move_domain_batch.(read from /root/batchmove) 20. Add a DNS entry 25. IP Usage
Choose option number 1 by typing 1 and hit <enter> Your screen will now ask you a series of questions. The first question will ask you for the domain name. Enter king.com And hit <enter> Next the account bot will ask you the username for this domain. You will see [king] next to the answer. In UNIX the [ ] denotes DEFAULT so by hitting <enter> it will automatically type whatever is between the [ ] for you. So just hit <enter> here because we want the username of the king.com domain name to be just king. You always want the username of each domain to be just the domain without the extension this way you can organize the /home drive easier because each directory will have a unique name. NOTE: all virtual domains will have their own group. In this case, the group is "kinggrp". All new users added to king.com will automatically belong to the group "kinggrp" The next question will ask for the Full Name. This is just used for accounting purposes and you can enter the name of the client who owns this virtual domain name here if you wish or you can leave it blank. By default it is always blank. Next the account bot will ask you for the password for this domain. The password can be any combination of UPPER case letters, lower case letters, numbers, or symbols. The password can be up to 8 characters long. Please make the password relatively difficult to ensure proper server security. Next up the account program will ask you to choose a disk quota for this domain. A disk quota is the amount of space in megabytes a virtual domain can occupy on the hard drive. This is especially useful to charge clients additional monthly fees when they run out of server space. Next it will ask you for the default email address for the domain king.com. By default this is the username@domain.com or in this specific case king@king.com. The next item on the list will ask if you want to install the business site scripts. These are just the 15 free CGI scripts that come with each virtual domain. These include a BBS, guestbook, counters, formmail, shopping cart and other scripts. If you are setting up this domain for retail use we suggest you give the client the extra scripts. Next the bot will prompt you to select if you want FrontPage extensions installed on the domain. Lastly, the account bot will ask if you want the remaining free site scripts installed. The default selection here is y because it will install things such as the Miva empresa engine and PHP4. The domain king.com is now ready to setup. The account bot will prompt you one last time to make sure you are satisfied with your choices. If you made a mistake simply press n and hit <enter> to redo the setup process or hit y and press <enter> and the domain will be setup instantly. Your screen should look like this: Your choice? 1 Full domain name? king.com who is the owner(username) of the domain?[king]: Full name(can be blank): Password:1234 Select disk quota for this domain: (a)2 megs (b)5 megs (c)10 megs (d)25 megs (e)50 megs (f)75 megs (g)100 megs (h)150 megs (i)500 megs (j)1000 megs (k)1500 megs (l)2000 megs (m)No quota Your choice ?: m Default email address in .redirect[king@king.com]:y Install full business site scripts?[y/n]:y Install frontpage(using the above username/password)?[y/n]:y Install new scripts?[y/n]:y Domain: king.com Username: king Password: 1234 Disk quota: None Default email address: y Basic site scripts: Yes New scripts: Yes Frontpage: Yes Cgiwrapper: Yes Satisfied with the above choices?[y/n] y The account bot will not setup the domain and assign an IP address to it. It will edit all appropriate files on the server and setup the virtual domain completely ready to use. Your screen should now show something similar to this: Guestbook installed. WWWboard installed. Installed click and go. Installed graphic counter. Shop cart installed. Anonymous ftp dir is /ftp/king wusage installed. Starting install, port: 80, web: "root web" Creating web http://www.king.com Install completed. Frontpage installed. htmlscript installed. Assigned IP number: 63.249.159.44 Notice the Assigned IP address for this domain is now 63.249.159.44. This is the IP address you can use to access the domain via the web. This is the IP that will be added to DNS so you can access king.com without having to know it is housed at 63.249.159.44 on your server. Our DNS is automated and will pick up the new domain king.com from your server within 10 minutes and add it to DNS. Should you change the IP of king.com in the future, the DNS will automatically refresh for you. You are now ready to use the account bot to setup a new domain or administer a current one. Explore the bot a little on your own, its full or useful tools for you, the webmaster.
--Setup bot This is a another proprietary tool constructed to help you administer your server with very little knowledge of the inner-workings of UNIX. The setup bot is used to fix problems with virtual domains on your server. To start the account bot simply type: setup and hit <enter>
noir:/www/conf# setup Setup menu: 1. Install/reinstall features 2. Mysql 3. Msql 4. Install a SSL certificate 5. Restart the RealAudio and Video server 6. Miscellaneous q. Quit. Your choice? If you select option number 1 the setup bot will prompt you to enter a domain name that resides on the server to administer. Once you do this will see a menu similar to this: Install Menu 1. All standard scripts 2. Guestbook 3. Wusage 4. Simple Search 5. Click and Go query box 6. Random text script 7. WWW Board Menu 8. Free For All Links page 9. Whois Query 10. Formmail.cgi 11.

Monsterbook 33. Raw Access Logs 34. BWI (Banner Wheel Industrial) 35. Index.cgi creation tool q. Quit. <enter> Return to main menu. Your choice? You can now choose from the 35 options above to install, re-install or repair broken scripts, PHP, Miva empresa and other things. If you hit <enter> it will return you back to the main menu and your screen will once again show: noir:/www/conf# setup Setup menu: 1. Install/reinstall features 2. Mysql 3. Msql 4. Install a SSL certificate 5. Restart the RealAudio and Video server 6. Miscellaneous q. Quit. Your choice?
From here you can choose option 2 if you wish to setup, administer, create or delete mySQL databases or users who can access certain databases. From here you can choose option 3 if you wish to setup, administer, create or delete mSQL databases or users who can access certain databases. From here you can choose option 4 if you want to setup SSL certificates for the server or for particular domains. NOTE: you must first run gencert domain.com And hit <enter> from a regular root prompt to generate the SSL keypair to send off to Thawte or Verisign. Option 5 from the menu will stop and restart the Real Audio/Video server for you automatically. If you choose option 6 your screen will display: Misc. menu: 1. Reinstall /ftp/supportteam directory 2. Limited-access user q. Quit. <enter> Return to main menu. Which lets you reinstall a FTP account or setup a limited-access user. The limited-access user function allows you to setup a FTP user to have only access to certain directories within your domain. For example, if you have king.com and you want an additional FTP to user to access only /home/www/king/newuser you could setup a limited-access user and they would only be able to FTP into that /newuser directory inside king.com. They could never accecss the index.html or other files that are stored in your /home/king/www directory.
