resnet fix

  1. As superuser, edit the /etc/rc.d/rc.local file. You can use a text editor like Emacs in a terminal to do this.
    NOTE: On some Linux systems, the file might be located at: /etc/rc.local. Ubuntu 6.1 is known to have the rc.local file located there.

  2. Add the following line to the end of the file:

    echo 1 > /proc/sys/net/ipv4/neigh/eth0/locktime

  3. Save the file, and restart your computer. The fix will now be applied on every system startup.

HOWTO: Nautilus script to mount/unmount .iso files

HOWTO: Nautilus script to mount/unmount .iso files

I recently found a Nautilus shell script on an older post to the forum that could mount .iso files, but it couldn't handle spaces in filenames or mount more than one file at once. After some struggle I've come up with these scripts which handle multiple concurrent mounts and filenames with spaces. You'll want to save these under ~/.gnome2/nautilus-scripts/ and make them executable:

Mount:

file.png File:~/.gnome2/nautilus-scripts/iso-mount.bash

#!/bin/bash
#
for I in "$*"
do
foo=`gksudo -u root -k -m "enter your password for root terminal
access" /bin/echo "got r00t?"`
sudo mkdir /media/"$I"
sudo mount -o loop -t iso9660 "$I" /media/"$I" && nautilus /media/"$I" --no-desktop
done
done
exit0


Unmount:

file.png File:~/.gnome2/nautilus-scripts/iso-umount.bash

#!/bin/bash
#
for I in "$*"
do
foo=`gksudo -u root -k -m "enter your password for root terminal
access" /bin/echo "got r00t?"`
sudo umount "$I" && zenity --info --text "Successfully unmounted /media/$I/" && sudo rmdir "/media/$I/"
done
done
exit0


To use either one just right-click on the .iso file and use scripts -> mount.

Notes

  • NOTE: The ISO file has to be in your home directory for this script to work.

HOWTO: Nautilus script to mount/unmount .iso, .nrg and .bin/.cue files

Below you will find Nautilus scripts that allow you to mount cdrom images in .iso, .nrg or .bin format.

You can mount multiple .iso or .nrg files, and up to 8 .bin files.

A shortcut is placed on your desktop for each mounted image for easy access.

Be sure to complete step 7, otherwise your new Nautilus scripts will not be available for use.

Most of the work was already done by the author of the Mount-ISO service menu for KDE.

1. Add the universe repository: http://easylinux.info/wiki/Ubuntu#How_to_add_extra_repositories

2. In order to mount .bin files, you need to install cdemu.

cdemu requires that you have the correct linux-headers package installed, so open a terminal, and choose the option that corresponds to your system.

Intel Pentium:

file.pngCode:

sudo apt-get install linux-686 linux-image-686 linux-headers-686 linux-restricted-formats-686


AMD K Series (Duron, Athlon, Sempron):

file.pngCode:

sudo apt-get install linux-k7 linux-image-k7 linux-headers-k7 linux-restricted-formats-k7


Older legacy PC (Intel Pentium Pro or 486):

file.pngCode:

sudo apt-get install linux-386 linux-image-386 linux-headers-386 linux-restricted-formats-386


Reboot to take advantage of the linux-headers, you've just installed.

3. Install cdemu.

Paste the following code into a text file and save the file to your desktop:

file.png File:~/Desktop/install-cdemu.sh

#!/bin/bash
#
# cdemu installer

apt-get install build-essential checkinstall automake1.6 libtool gcc-3.4

cd ~/Desktop
wget http://robert.private.outertech.com/virtualcd/cdemu-0.7.tar.bz2
tar xjf ~/Desktop/cdemu-0.7.tar.bz2
cd ~/Desktop/cdemu-0.7
ls -la /lib/modules/`uname -r`/build
make
make install

cd ~/Desktop
sudo rm -r cdemu-0.7

modprobe cdemu


Open a terminal:

file.pngCode:

cd ~/Desktop
sudo chmod +x install-cdemu.sh
sudo sh install-cdemu.sh


Wait for the installation to finish, then enable the cdemu module:

file.pngCode:

sudo gedit /etc/modules


Add this line to the end of the /etc/modules file:

file.pngCode:

cdemu


Save the file.

4. Mount-CDImage Nautilus script.

Paste the following code into a text editor and save the file under your nautilus-scripts directory:

file.png File:~/.gnome2/nautilus-scripts/mount-cdimage

#!/bin/bash
# Mount ISO NRG BIN/CUE

# Get filename extension and make it lower-case
EXT=`echo $1 | sed -e 's/.*\.//'`
EXT_LOW=`echo $EXT | tr 'A-Z' 'a-z'`

# Get the filename without the extension
BASE="`echo "$1" | sed 's/\.[^.]*$//'`"

# Mount ISO
if [ $EXT_LOW == "iso" ]; then
foo=`gksudo -u root -k -m "enter your password for root terminal access" /bin/echo "got r00t?"`
sudo mkdir /media/"$BASE" &&
sudo mount -o loop,ro,nodev,noexec,nosuid "$1" /media/"$BASE" &&
## Uncomment the next line, if you prefer to have an extra link to the ISO image placed on the desktop.
#ln -s "/media/${BASE}" "/home/$USER/Desktop/${BASE}" &&
gnome-open "/media/${BASE}"
fi

# Mount NRG
if [ $EXT_LOW == "nrg" ]; then
foo=`gksudo -u root -k -m "enter your password for root terminal access" /bin/echo "got r00t?"`
sudo mkdir /media/"$BASE" &&
sudo mount -o loop,ro,nodev,noexec,nosuid,307200 "$1" /media/"$BASE" &&
## Uncomment the next line, if you prefer to have an extra link to the NRG image placed on the desktop.
#ln -s "/media/${BASE}" "/home/$USER/Desktop/${BASE}" &&
gnome-open "/media/${BASE}"
fi

# Mount BIN/CUE
if [ $EXT_LOW == "cue" ]; then

# Find a free node to mount
NODE=$((`cdemu -s | cut -f 8 -d " " | grep 0 -n -m 1 | cut -c 1`-2))

if [ $NODE -lt "0" ]; then
zenity --info --text "You can not mount any more BIN/CUE files."
fi

# Node needs to be between 0 and 7
if [ $NODE -ge "0" -a $NODE -le 7 ]; then
foo=`gksudo -u root -k -m "enter your password for root terminal access" /bin/echo "got r00t?"`
sudo mkdir -p "/media/${BASE}" &&
cdemu $NODE "$1" &&
sudo mount -t iso9660 /dev/cdemu/${NODE} "/media/${BASE}" &&
ln -s "/media/${BASE}" "/home/$USER/Desktop/${BASE}" &&
gnome-open "/media/${BASE}"
fi

# If directory is empty, then release cdemu
if [ "$(ls -A /media/${BASE})" ]; then
echo
else
cdemu -u $NODE
fi

fi

# If directory is empty, then remove empty directory
if [ "$(ls -A /media/${BASE})" ]; then
echo
else
sudo rmdir /media/"${BASE}"
fi


5. UnMount-CDImage Nautilus script.

Paste the following code into a text editor and save the file under your nautilus-scripts directory:

file.png File:~/.gnome2/nautilus-scripts/unmount-cdimage

#!/bin/bash
# Unmount ISO NRG BIN/CUE

BASE="$1"

# Get filename extension and make it lower-case
# EXT_LOW will be iso, nrg, cue or nonsense
EXT=`echo $1 | sed -e 's/.*\.//'`
EXT_LOW=`echo $EXT | tr 'A-Z' 'a-z'`

# Isolate the the basename without the extension (in case this is not the case already)
if [ $EXT_LOW == "iso" -o $EXT_LOW == "nrg" -o $EXT_LOW == "cue" -o $EXT_LOW == "volume" ]; then
BASE="`echo "$1" | sed 's/\.[^.]*$//'`"
fi

# Release /dev/cdemu according to whether BIN uses /dev/cdemu0 or /dev/cdemu/0
foo=`gksudo -u root -k -m "enter your password for root terminal access" /bin/echo "got r00t?"`
DEV="`mount | grep "$BASE" | cut -f1 -d " "`"

if [ ${DEV##/dev/cdemu/} -ge 0 -a ${DEV##/dev/cdemu/} -le 7 ]; then
cdemu -u ${DEV##/dev/cdemu/}
fi

if [ ${DEV##/dev/cdemu} -ge 0 -a ${DEV##/dev/cdemu} -le 7 ]; then
cdemu -u ${DEV##/dev/cdemu}
fi

# Unmount
foo=`gksudo -u root -k -m "enter your password for root terminal access" /bin/echo "got r00t?"`
sudo umount /media/"${BASE}"
sudo rmdir /media/"${BASE}"
sudo rm /home/$USER/Desktop/"${BASE}"


6. Create-CUESheet Nautilus script.

This Nautilus script creates a .cue file from a .bin file, if the .cue is missing. A .cue file is required to mount a .bin file. This only works for basic .bin files. If your .bin file happens to be a multi-track CD image, you will need specialized software to create a more advanced .cue file.

Paste the following code into a text editor, and save the file under your nautilus-scripts directory:

file.png File:~/.gnome2/nautilus-scripts/create-cuesheet

#!/bin/bash
# Create CUE for BIN

# Isolate the filename without the extension.
BASE=`echo "$1" | sed 's/\.[^.]*$//'`

cat <<> "${BASE}.cue"
FILE "$1" BINARY
TRACK 01 MODE1/2352
INDEX 01 00:00:00
EOF


7. Open a terminal:

file.pngCode:

sudo chmod 700 ~/.gnome2/nautilus-scripts/*

fglrx problems

ok, so i used a guide i obtained earlier to configure my video card drivers and in the past this has worked fine. but now the OS refuses to load them. i even tried to manually edit the xorg.conf file but its already listing the correct diver to load. ive posted on some forumes, we'll see what happens.
