  3. Unmounted SATA HDD is still visible

    in Hardware

    Posted

    Hi there,

     

    I recently added a secondary SATA HDD to my old Mandrake 10.1 desktop. The drive is recognized as /dev/sda1 and is formatted as ext3 filesystem. MDK was unable to mount it properly on start up, and I added the following entry to /etc/fstab 

     /dev/sda1 /backup ext3 umask=0,user,iocharset=iso8859-1,sync,kudzu,codepage=850,noauto,exec,users 0 0

    Despite that, the drive was painfully slow until I manually unmounted and mounted it with a command

    mount -t ext3 /dev/sda1 /backup

    After that I could read and write to the HDD OK. The problem is that I have to mount the drive manually after every reboot. If I don't, then

     

    1. ls lists a different list of files on the drive from what should be there! I suspect those files were put there while the drive was not mounted properly

     

    2. Why can I see anything at all on the partition /backup after it has been unmounted?

     

    Here is what I mean

    # mount
/dev/hda1 on / type ext3 (rw)
none on /proc type proc (rw)
none on /proc/bus/usb type usbfs (rw)
none on /sys type sysfs (rw)
/dev/hda6 on /home type ext3 (rw)
none on /mnt/floppy type supermount (rw,sync,dev=/dev/fd0,fs=ext2:vfat,--,umask=0,iocharset=iso8859-1,codepage=850)
# ls /backup
a-Fri.tgz  a-Sat.tgz  a-Thu.tgz  a-Wed.tgz
a-Mon.tgz  a-Sun.tgz  a-Tue.tgz

    Note that the partition /backup and device /dev/sda1 are not on the list of mounted partitions, yet ls /backup shows there are files on it! Where can I find those files? They disappear after the HDD is mounted manually.

  4. Better font rendering for emacs (2009.0)?

    You can change the size of the Emacs window by adding these lines to the Emacs configuration file ~/.emacs

    (custom-set-variables
;; custom-set-variables was added by Custom -- don't edit or cut/paste it!
;; Your init file should contain only one such instance.
'(blink-cursor nil)
;;;  I think this should be a single line. Note Width and Height parameters, they give you 80 columns and 46 lines of text in the emacs
;;;  window. Change them to what suits you. And yes, you can cut and paste it :-)
'(default-frame-alist (quote ((scroll-bar-foreground . "white") (scroll-bar-background . "grey75") (foreground-color . "Black") (background-color . "White") (vertical-scroll-bars . right) (tool-bar-lines . 0) (menu-bar-lines . 1) (width . 80) (height . 46))))
'(menu-bar-mode t)
'(mouse-wheel-mode t nil (mwheel))
'(pc-select-meta-moves-sexps t)
'(pc-select-selection-keys-only t)
'(pc-selection-mode t nil (pc-select))
'(scroll-bar-mode (quote right))
'(show-paren-mode nil nil (paren))
'(tool-bar-mode nil nil (tool-bar)))
;; '(x-select-enable-clipboard t))

     

    Alternatively, you can try adding this line to ~/.Xdefaults (again, change the values) 

    emacs.geometry: 80x46

  5. Hotmail doesn't work any more [solved]

    in Software

    Posted

    Perhaps, the right thing would be to complain to Hotmail customer service. Even though you don't pay for the account, you entered in a contract with them by opening an account. Unlikely, this will go further than polite suggesting that you should have used the MSIE to access that service, but it is better than just walking away without letting them know about the compatibility issues.

  7. 2009.0 Free DVD: Emacs 22.3 can't find fonts

    It is not very clear from your post how you are making modifications in the .emacs. You can simply add whatever you need to the .emacs, though the syntax is a bit cumbersome. Another method is making modifications in the Customize Emacs buffer. To reach it open Emacs, then go to Options->Customize Emacs->Specific Face, then hit "Enter" to open the buffer. Note gray buttons near the top of the buffer:

     Set for Current Session
Save for Future Sessions
Undo Edits
Reset to Saved
Erase Customization 
Finish

    To make permanent changes and save them in the .emacs file, you must click "Save for Future Sessions". Make sure you have write permissions for that file.

     

    To change a particular font/face browse to the font/component you would like to modify, and click the Show Face button. Make modifications (note that there is a preview - the word "sample"), then scroll back to the top of the buffer and click one of the buttons mentioned above. You can initially set changes for the current session (without modifying .emacs), then if you are happy with them, return to the Customize Emacs buffer, and click Save for Future Sessions.

     

    Edit: Here is a discussion on how to permanently turn off auto-fill http://groups.google.com/group/gnu.emacs.h...6e78a16d7d7bc0f

    On my 2008.0 laptop, only font that matches the mask -*-*-*-*-*-*-16-*-*-*-*-*-iso8859-1 is -sony-fixed-medium-r-normal-*-16-*-*-*-c-*-iso8859-1. It seems to be available in both 100x100 and 75x75 point sizes. The corresponding font files are in the directory /usr/share/fonts/misc/, according to the file /usr/share/fonts/misc/fonts.dir:

     $ more misc/fonts.dir |grep sony
12x24.pcf.gz -sony-fixed-medium-r-normal--24-170-100-100-c-120-iso8859-1
12x24rk.pcf.gz -sony-fixed-medium-r-normal--24-170-100-100-c-120-jisx0201.1976-0
8x16.pcf.gz -sony-fixed-medium-r-normal--16-120-100-100-c-80-iso8859-1
8x16rk.pcf.gz -sony-fixed-medium-r-normal--16-120-100-100-c-80-jisx0201.1976-0

    They are part of the package x11-font-sony-misc. You may want to check whether you have this package installed, hopefully 2009 uses the same naming convention.

     

    You can copy/create your own ~/.Xdefaults in the user account. If you like, you can copy the one in the root account and modify it at will. I noticed that your root's .Xdefaults includes

    emacs*font: fixed

    Did you try commenting it out? Just put ! at the start.

     

    Text wrapping as well as splash screen can be turned on/off in ~/.emacs file. Here is the section from my ~/.emacs that turns on autofill (text wrapping) and turnes off the splash screen

    (setq initial-major-mode
  (lambda ()
	(text-mode)
	(turn-on-auto-fill)
(font-lock-mode)
))

(setq font-lock-mode-maximum-decoration t)
(require 'font-lock)

;; By default turn on colorization.
(if (fboundp 'global-font-lock-mode)
(global-font-lock-mode t)
 )

;; Turn on auto-fill mode in text mode and related modes.
(add-hook 'text-mode-hook
		'(lambda () 
		 (setq fill-column 75)
		 (auto-fill-mode 1)))


;; Enable this if you don't want to see emacs start-up message 
(setq inhibit-startup-message t)

    Do you have xfontsel installed? Does it show that these fonts are available?

     

    Also, check /etc/X11/app-defaults/Emacs. If you find what those fonts are used for, you could replace them by editing that file, but it is better to edit your local ~/.emacs or ~/.Xdefaults files. For example, I have these lines in my ~/.Xdefaults

     

    ! emacs, xemacs
emacs*bitmapIcon: on
emacs.font-latex-math-face.attributeForeground: Red

     

    As a last resort, you might need to install and run X font server xfs. AFAIK, recent versions of xorg do not use xfs . That may be a better option for KDE/Gnome apps, but causes problems for those few of us who use emacs.

     

    Edit: Just found that only one line in my /etc/X11/app-defaults/Emacs refers to the medium-r-normal font: 

    ! *EmacsFrame.FontSet: -dt-interface user-medium-r-normal-s*-*-*-*-*-*-*-*-*

    As you can see it is commented out.

  14. switch from ubuntu back to Mandriva [solved]

    in Other Linux and Unix Distributions

    Posted

    Thanks! One problem though - drakboot crashed and nothing happened :-). Now I am trying to edit menu.lst manually. Here is the Mandriva original menu.lst:

     

    timeout 10
color black/cyan yellow/cyan
gfxmenu (hd0,5)/boot/gfxmenu
default 0

title linux
kernel (hd0,5)/boot/vmlinuz BOOT_IMAGE=linux root=/dev/sda6 resume=/dev/sda7 acpi_slip=s3_bios acpi_osi=!Linux splash=silent vga=791
initrd (hd0,5)/boot/initrd.img

title linux-nonfb
kernel (hd0,5)/boot/vmlinuz BOOT_IMAGE=linux-nonfb root=/dev/sda6 resume=/dev/sda7 splash=silent
initrd (hd0,5)/boot/initrd.img

title failsafe
kernel (hd0,5)/boot/vmlinuz BOOT_IMAGE=failsafe root=/dev/sda6 failsafe
initrd (hd0,5)/boot/initrd.img

title windows
root (hd0,0)
makeactive
chainloader +1

     

    There is the parameter in BOOT_IMAGE=xyz in each linux entry of the list, but I don't see an equivalent in Ubunu. What am I suppose to put there? This is what I am going to insert between the last linux entry and the windows entry

     

    title Ubuntu 8.04, kernel 2.6.24-16-generic
kernel (hd0,8)/boot/vmlinuz-2.6.24-16-generic BOOT_IMAGE=???????? root=/dev/sda9 ro quiet splash
initrd (hd0,8)/boot/initrd.img-2.6.24-16-generic

    By the way what does gfxmenu (hd0,5)/boot/gfxmenu do? Does this need to be changed to reflect added grub entries?

  15. switch from ubuntu back to Mandriva [solved]

    in Other Linux and Unix Distributions

    Posted

    Ok, here is the entry from the Ubuntu's menu.lst. Ubuntu is on /dev/sda9, Mandriva is on /dev/sda6

     

    title		   Ubuntu 8.04, kernel 2.6.24-16-generic
root			(hd0,8)
kernel		  /boot/vmlinuz-2.6.24-16-generic root=UUID=0ca7a84f-3184-4e26-a076-855a22b8e24a ro quiet splash
initrd		  /boot/initrd.img-2.6.24-16-generic
quiet

     

    Next, I went to MCC -> Boot -> Set up boot system -> Add. Could somebody please help me filling out the boxes?

     

    * Label: That's easy, Ubuntu 8.04

     

    * Image: In the pull-down menu, i have only mandriva related ones. Should I simply type in /boot/vmlinuz-2.6.24-16-generic Will the boot loader understand that I am referring to the Ubuntu's /boot dir and not the Mandriva's /boot dir?

     

    * Root: I don't understand what UUID=0ca7a84f-3184-4e26-a076-855a22b8e24a means. Should I simply select /dev/sda9 from the pull down menu? Besides, MCC won't let me type in anything anyway.

     

    * Append: Do I put here ro quiet , or should these go elsewhere?

     

    * Default: Easy, leave unchecked

     

    Advanced options:

     

    * Videmode: I suspect this can be left blank

     

    *Initrd: Again, what do I put here, /boot/initrd.img-2.6.24-16-generic from the Ubuntu's list? Mandriva shows only several Mandriva related options.

     

    * Network profile: I suspect this can be left blank

     

    Finally where do I put quiet from the last line?

    Ah, if only I knew the trick about 32Mb partition before...

     

    Now, about arctic's suggestion that it can be done within MCC, when I go to MCC->Boot->Setup boot system (it takes a little while until the window is populated) -> Next, then I only see the Mandriva's grub menu. Are you saying I could simply cut and paste Ubuntu's entries into "ADD" fields? Now, where do I change the faceless "linux (/sda6)" to a more friendly name like "mandriva linux", which I had before?

  25. Stopping Shorewall blocks access to the computer

    in Security

    Posted

    I have an ssh server running on my laptop behind the firewall (shorewall). With firewall running, everything is fine, and I can connect to the machine via ssh just fine. However, shutting down the shorewall service on the laptop prevents other computers from connecting to ssh server. This does not look logical to me.... Why is this happening? What is blocking connections? I need to be able to test certain things with shorewall down.
