To get an account on kahuna you must be a registered Engineering student. You can apply for your account online at: http://kahuna.sdsu.edu/account.html Or you can contact Christopher Paolini at 594-7159.
When your kahuna account was created, a directory named public_html in your home directory should have also been created. Inside this directory is a file named index.html which is your default home page. To customize your home page, edit this file and once you are satisfied with the contents you can set the permissions on your page and notify the webmaster to add it to the home page list by executing the following command:
kahuna% /usr/local/apache/htdocs/pubwebIf you don't have a public_html directory you will need to create one:
kahuna% cd ~ kahuna% mkdir public_htmlNext cd to your public_html directory and create an index.html file.
kahuna% cd ~/public_html kahuna% touch index.htmlThen edit your index.html to contain whatever information you want (see item 4). Once you are satisfied with the contents execute:
kahuna% /usr/local/apache/htdocs/pubweb
First verify the proper permissions are set on your home directory and public_html directory. For your home directory, the proper permissions are
drwx--x--xYour public_html directory should have permissions
drwxr-xr-xAlso, your main page, index.html, should be publicly readable and have permissions
-rw-r--r--You can configure these permissions by executing the following command from the shell:
chmod 711 $HOME; chmod 755 $HOME/public_html; chmod 644 $HOME/public_html/index.htmlOnce these permissions are set, you should be able to view your home page using a web browser via the following URL:
http://kahuna.sdsu.edu/~your_username/
where your_username is your unique username for kahuna.sdsu.edu which was assigned when you obtained an account.
If you don't know HTML there are a number of tools available to help you create web pages. asWedit is available for use on kahuna in an Xsession. Type asWedit at the kahuna% prompt in an xterm to use it.
Your home page does not need to be registered to been seen on the web. Once completed your page can be accessed using the URL: http://kahuna.sdsu.edu/~your_username/
Execute the command: kahuna% /usr/local/apache/htdocs/pubweb Or send email to webmaster@kahuna.sdsu.edu. Include your name, major and the location of the page.
To change your password on kahuna, invoke the passwd(1) command as follows: 1 [kahuna]/student/joeuser> passwd You will then be prompted for your current password. This constraint prevents unscrupulous students from changing your password while you are away from your terminal for period of time. passwd: Changing password for joeuser Enter login password: <Enter your CURRENT password here> New password: <Enter the NEW password which you want here> Re-enter new password: <Enter the NEW password AGAIN which you want here> If all goes well, you will receive a shell prompt which indicates your password has been successfully changed. If you receive a message such as: Password must contain at least two alphabetic characters and at least one numeric or special character. You probably forgot to include a numeric character in your password. I know it's a hassle, but you will need to put a number or "special" character in your password. Here are some special characters which will work: !,@,#,$
The Network Of Workstations (NOW) cluster in E-300 uses a password different from kahuna, even though they may be initially the same when you receive a new account. If you wish to change the password you use to access the UltraSPARC systems in E-300, which support the Berkeley NOW network and Pro/ENGINEER, you must perform the following two steps:
(1) Use telnet or Secure Shell (ssh) to log into the GLUnix master server, davinci.sdsu.edu:
90 [kahuna]/home/paolini> telnet davinci Trying 130.191.163.100... Connected to davinci. Escape character is '^]'. SunOS 5.6 login: paolini Password: ******* Last login: Thu Jul 23 15:39:24 from localhost Sun Microsystems Inc. SunOS 5.6 Generic August 1997 1 [davinci]/home/paolini>
(2) Use the passwd -r nisplus command on davinci to change your NIS+ password:
79 [davinci]/home/paolini> passwd -r nisplus passwd: Changing password for paolini Enter login(NIS+) password: (Enter the password you just used to login to davinci) New password: (Enter a new password of your choosing) Re-enter new password: (Re-enter the new password for verification) NIS+ password information changed for paolini
If all goes well, you will receive a message similar to the following:
NIS+ password information changed for paolini NIS+ credential information changed for paolini
After running passwd -r nisplus, you should log off davinci and wait 15 - 20 minutes for the NIS+ password and credential changes to take effect.
If you are using Pro/ENGINEER in room Engineering 300 and wish to save your part and assembly files on a 3.5" floppy diskette, use the mtools suite of diskette utilities (see http://mtools.linux.lu for complete details). If you are using a new floppy or wish to completely overwrite an existing diskette, first format the disk using the Solaris fdformat utility:
10 [virtue]/export/home/paolini> fdformat Formatting 1.44 MB in /vol/dev/rdiskette0/unnamed_floppy Press return to start formatting floppy. (<-- press return when prompted to do so) ................................................................................After formatting a floppy, you must add an MSDOS filesystem to a newly formatted floppy disk using the mformat utility. To label the filesystem, use the -v command line option and specify an eleven character maximum length string for a label:
20 [virtue]/export/home/paolini> mformat -v 'PROE Files' a:When the mformat process completes, you can use the mdir command to obtain a directory listing of the MSDOS filesystem:
21 [virtue]/export/home/paolini> mdir
Volume in drive A is PROE Files (abbr=PROE FILES )
Volume Serial Number is 4B95-7459
Directory for A:/
No files
1 457 664 bytes free
Finally, you can copy part and assembly files to the floppy using the
mcopy command. Suppose your current working directory contains the
following files that comprise a design:
37 [virtue]/export/home/paolini/mdx> ls total 410 66 crank.prt* 62 triangle_bde.prt* 66 block.prt* 90 four_bar.asm* 66 block2.prt* 60 triangle_abc.prt*and you wish to copy all part and assembly files to the floppy. Use the mcopy command as follows:
33 [virtue]/export/home/paolini/mdx> mcopy *.prt *.asm a:After the mcopy process completes, verify the files were indeed copied to the disk:
34 [virtue]/export/home/paolini/mdx> mdir
Volume in drive A is PROE Files (abbr=PROE FILES )
Volume Serial Number is 66EF-A28F
Directory for A:/
block prt 33115 04-06-2001 18:00 block.prt
