FAQ Overview

• Set the camera to manual exposure mode
• Enable RAW recording mode
• Set focus to manual
• Set the focus ring to infinity (rotate the ring completely in, then back it off slightly). TIP: once focus is achieved, use masking tape to "lock" the focus ring in place.
• Use at lest one of the following to help the camera to settle from any vibrations
• Self Timer
• Remote trigger
• Set white balance to auto or AWB
• Enable long exposure noise reduction or take dark frame (shutter closed)
• Enable live view mode if supported to assist with focusing
• Enable mirror lock if supported (prevents vibrations from the mirror flipping up)
• Choose an exposure setting (the lower the f/ratio, the better), then adjust as necessary. Don't forget the rule of 600.
• f/1.4, ISO 1600, 30 seconds
• f/2, ISO 3200, 30 seconds
• f/2.8, ISO 6400, 30 seoncds
• f/3.5, ISO 10000, 30 seconds
• f/4, ISO 12800, 30 seconds

The rule of 600 is the general rule of thumb when it comes to landscape astrophotography. It basically dictates the maxium exposure time based on the focal length of your camera lense. It helps you figure out the amount of time you can expose your sensor without creating star trails or oval stars as the earth rotates under the star field. It's worth noting that it is a starting point. Sometimes it's necessary to calculate the exposure time, then decrease it by a little bit.

The equation is simple: 600 / focual length = exposure time. For example, if your lense is 50mm, the maximum exposure you should take is 12 seconds (600/50 = 12). Here are some more examples:

• 18mm focal length: 600 / 18 = 33
• 24mm focal length: 600 / 24 = 24
• 30mm focal length: 600 / 30 = 20

The following procedure is pretty standard and works on most Cisco devices.

• Connect to the device via it's console port setting your terminal emulator to 9600/8/N/1 and power cycle it.
• As soon as it starts to POST, send it a BREAK signal (depends on your terminal emulator) to drop it into ROMMON.
• At the prompt, type confreg 0x2142
• Then type reset and let the device reboot completely (do not use ctrl-c to skip config dialog).
• After the device comes up, go into enable mode
• copy startup-config running-config
• show run to make sure it looks good.
• Go into config mode (config t)
• Enter the new secret password (enable secret)
• Make sure to do a no shut on all the interfaces that should be up.
• Type config-register 0x2102.
• Type end to exit config mode.
• Save the config using write mem.

1. Hold down the mode button located on the left side of the front panel, while you reconnect the power cable to the switch.
2. flash_init
3. load_helper
4. dir flash:
5. rename flash:config.text flash:config.old
6. boot
7. enable
8. rename flash:config.old flash:config.text
9. copy flash:config.text system:running-config
10. config t
11. Fix config.
12. wr mem

1. Connect a console cable to the AP and log in with the username "cisco" and the password "Cisco".
2. Go into enable mode using the password "Cisco".
3. clear lwapp private-config
4. clear lwapp ap ip address
5. clear lwapp ap ip default-gateway
6. clear lwapp ap controller ip address
7. lwapp ap ip address <ip_address> <netmask>
8. lwapp ap ip default-gateway <gateway_ip>
9. lwapp ap controller ip address <wlc_ip_address>
10. show capwap ip config

• First, find the session index for the user you want to disconnect: show vpn-sessiondb anyconnect
• Disconnect by index number: vpn-sessiondb logoff index <index> noconfirm

• Define an ACL to describe the traffic to capture

config t
access-list 144 permit ip host 10.10.10.1 host 10.10.20.2
access-list 144 permit ip host 10.10.20.2 host 10.10.10.1
end

• Define a capture buffer (This is where the frames are stored once captured)

monitor capture buffer holdpackets filter access-list 144

• Define a capture point. This gives the user the ability to be more granular on what interface, switching path the frames are captured.

monitor capture point ip cef icmptrace all both

• Associate the capture point with the capture buffe.You can associate multiple points to the same buffer.

monitor capture point associate icmptrace holdpackets

• Start the capture

monitor capture point start icmptrace

• View the capture and/or export it to a PCAP file for offline analysis

show monitor capture buffer holdpackets parameters
monitor capture buffer holdpackets export tftp://192.168.5.40/captureut.pcap

• Stop the trace

monitor capture point stop icmptrace

• Delete the capture buffer

no monitor capture buffer holdpackets

• First, set the environment variables to describe the IP settings for the WAP. In this example I'm using 10.1.94.99/24 with a gateway of 10.1.94.1.

set IP_ADDR 10.1.94.99

set NETMASK 255.255.255.0

set DEFAULT_ROUTER 10.1.94.1

• Then prepare the bootloader to use the TFTP and flash file systems as well as the ethernet interface:

tftp_init

ether_init

flash_init

• Next, extract the image from the TFTP server to the flash file system. In this scenarioe, I'm using the tar file c1200-k9w7-tar.123-8.JEE.tar on the TFTP server at 10.1.94.17.

tar -xtract tftp://10.1.94.17/c1200-k9w7-tar.123-8.JEE.tar flash:


• Use the "dir flash:" command to show the contents of the flash file system. You should see the image that was just downloaded from the TFTP server. In this case, the image name is c1200-k9w7-mx.123-8.JEE.

dir flash:

set BOOT flash:c1200-k9w7-mx.123-8.JEE/c1200-k9w7-mx.123-8.JEE

• Verify your work using the "set" command.

ap: set
BOOT=flash:c1200-k9w7-mx.123-8.JEE/c1200-k9w7-mx.123-8.JEE
DEFAULT_ROUTER=10.1.94.1
ENABLE_BREAK=no
IOS_NAME_SERVER_ADDR=192.168.1.25
IP_ADDR=10.1.94.99
MANUAL_BOOT=no
NETMASK=255.255.255.0

• Finally, use the "boot" command to boot the AP. It should now work as expected, and if there was a previous config (the file "config.txt" in the directory listing above, it should load it and run like normal.

Follow this procedure to upgrade an HA pair of ASAs without any downtime. Note that when upgrading to a new release, the pair must both be upgraded to the lastest version of the prior release first.  

• Download the new software to both units, and specify the new image to load with the "boot system" config command. If necessary, download a new ASDM image and new AnyConnect packages as well. Reconfigure the primary with this info using the "asdm image" and "webvpn" configuration.

• Reload the standby unit to boot the new image by entering the following command on the active unit:

active# failover reload-standby

• When the standby unit has finished reloading, and is in the "Standby Ready" state, force the active unit to fail over to the standby unit by entering the following command on the active unit.

active# no failover active

• Reload the former active unit (now the new standby unit) by entering the following command:

newstandby# reload

• When the new standby unit has finished reloading, and is in the "Standby Ready" state, return the original active unit to active status by entering the following command:

newstandby# failover active

update user set password=PASSWORD("NEWPASSWORD") where User='root';

These files are binary logs which contain statement events which have updated the database. Typically, these are used in scenarios where the database is replicated between servers. If you're not using replication, however, these files do little more than clutter up your disk.

To stop MySQL from creating these files, simply edit your my.cnf file (probably /etc/mysql/my.cnf) and comment out the line that reads:

log-bin

1. Log into the database with root/sa priveleges.

2. Issue the command:

   	grant all on database.* to 'username'@'localhost' IDENTIFIED BY 'clear_password';
   
   	

Note: It is not necessary to flush priveleges when using the "grant" syntax above.

1. Sync the config between the two appliances if needed.
2. If running ASM, sync the policies.
3. If running APM, sync the policies.
4. Download the Base image and the latest hotfix.
5. Import the base image and the hotfix into both the active and standby appliance.
6. Reactivate the license on both appliances.
7. Generate a new UCS archive of each appliance and save them off of the box.
8. Perform the install into a clean partition on both appliances.
1. The install is behind the scenes and does not interrupt traffic therefor this can be done on both the active and standby.
2. If you launch the install from the hotfix it will install both the base image and the hotfix together at the same time saving a step of installing the base image and then the hotfix.
9. Reboot the standby unit (Unit 2) to the newly upgraded volume.
10. Confirm the configuration has loaded and all pools and VIPS are green.
11. Failover to Unit 2 and confirm this is passing traffic as expected.
12. When Unit 2 is confirm to be good, reboot Unit 1 into the upgraded volume.
13. Confirm the configuration has loaded and all pools and VIPS are green.
14. Fail back over to Unit 1 and confirm this is passing traffic as expected.

• To view the management route, type the following command:

tmsh list /sys management-route

• To view all existing routes, type the following command:

tmsh show /net route

• To add a static route for traffic to use the management network, use the following command syntax:

tmsh create /sys management-route <name> network \
<dest_net>/<netmask> gateway <mgt_gw>

For example:

tmsh create /sys management-route dns1 network \
     8.8.8.8/255.255.255.255 gateway 10.129.1.1
tmsh create /sys management-route dns2 network \
     8.8.4.4/255.255.255.255 gateway 10.129.1.1
tmsh create /sys management-route ntp1 network \
     10.1.1.1/255.255.255.255 gateway 10.129.1.1
tmsh create /sys management-route ntp2 network \
     192.168.1.3/255.255.255.255 gateway 10.129.1.1

• To delete an existing static route for the management network, type the following command:

tmsh delete /sys management-route <name>

• To save any changes made to the static routes for the management network,type the following command:

tmsh save /sys config

Edit /etc/lightdm/lightdm.conf.d/10-xubuntu.conf so that it looks like this:

[SeatDefaults]
user-session=xubuntu
allow-guest=false

• apt-get install xubuntu-desktop
• Log out, log back in, selecting Xubuntu/Xfce as my interface
• Chill out for a few days. See that things still work. There will be too many applications (eg there will be both GNOME's and Xfce's default applications available but you want to make sure you'll have everything you need when you remove GNOME/Unity/Whatever.
• apt-get remove ubuntu-desktop
• apt-get autoremove

• Edit /etc/sysctl.conf and add the following lines at the bottom:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

•  Reconfigure kernel runtime paramaters using the command sysctl -p
• Verify it worked
• cat /proc/sys/net/ipv6/conf/all/disable_ipv6 (should return a value of "1")
• ifconfig -a (the IPv6 addresses should be gone)

• Install the encryption package

apt-get install ecryptfs-utils

• Create the user account

adduser --uid xxxx --gid yyyy --encrypt-home username

Add the APT repository, update and install the app
sudo add-apt-repository ppa:alessandro-strada/ppa
sudo apt-get update
sudo apt-get install google-drive-ocamlfuse

Add your username to the fuse group
sudo usermod -a -G fuse <username>

Give permission to access your account
google-drive-ocamlfuse
(choose "Accept" when browswer opens)

Create a mount point
mkdir ~/googledrive

To mount the Google drive file system
google-drive-ocamlfuse ~/googledrive

To unmount
fusermount -u ~/googledrive

Add the Java repository and update the package list

add-apt-repository ppa:webupd8team/java apt-get update

Check the current running version of Java. Assuming you're runing OpenJDK, remove it.

java -version apt-get purge openjdk-\*

Installt he Oracle version of Java.

apt-get install oracle-java8-installer oracle-java8-set-default

Verify it.

java -version

This example creates an encrypted file system: on /dev/sda3 using dm-crypt with LUKS. It's based on Debian and applies to other Debian distros.

• Install the necessary packages

apt-get install cryptsetup


• setup the partition

cryptsetup luksFormat /dev/sda3 (give it a passphrase)

• open (unlock) the partition

cryptsetup luksOpen /dev/sda3 sda3

• format the partition (assumes XFS)

mkfs.xfs /dev/mapper/sda3


• Add to /etc/fstab

/dev/mapper/sda3        /share    xfs             noauto  0       0

• add the following to sudo if you want a non-root user to be able to mount it

username     ALL = NOPASSWD:/sbin/cryptsetup
username     ALL = NOPASSWD:/bin/mount
username     ALL = NOPASSWD:/usr/sbin/xfs_check

• The following is a simple shell script to open and mount the partition on /share

#!/bin/sh
cryptsetup luksOpen /dev/sda3 sda3
mount /dev/mapper/sda3 /share

• List all certificates

certutil -d sql:$HOME/.pki/nssdb -L

• List details of a certificate

certutil -d sql:$HOME/.pki/nssdb -L -n <certificate nickname>

• Delete a certificate

certutil -d sql:$HOME/.pki/nssdb -D -n <certificate nickname>

• Retrieve remote certificate and store it in home.pem

echo | openssl s_client -connect server_name:443 \
2>&1 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > file_name.pem

• Note: to trust a self-signed server certificate, we should use

certutil -d sql:$HOME/.pki/nssdb/ -A -t "P,," -n server_name -i file_name.pem

• due to NSS bug 531160, workaround is:

certutil -d sql:$HOME/.pki/nssdb/ -A -t "C,," -n server_name -i file_name.pem

Type "chrome://flags" in the URL bar and make the modifications below. Tip: use CTRL+F to find the option names.

• Set Maximum tiles for interest area to 512
• Set Number of raster threads to 4
• Enable SPDY/4
• Enable Accelerated overflow scroll
• Enable fast tab/windows close
  

First, boot the affected computer from a live usb or cd. Then mount the root file system on /mnt (assumes the hard drive you want to install grub on is /dev/sda).

mount /dev/sda2 /mnt

If necessary, mount /boot

mount /dev/sda1 /mnt/boot

Mount the virtual file systems /dev/, proc, etc

mount --bind /dev /mnt/dev
mount --bind /dev/pts /mnt/dev/pts
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys

Chroot into the mounted environment.

sudo chroot /mnt

Install grub.

grub-install /dev/sda

Generate a grub config file.

update-grub

Exit the chroot environment and unmount the file systems.

exit
umount /mnt/sys
umount /mnt/proc
umount /mnt/dev/pts
umount /mnt/dev
umount /mnt

Reboot!

While not in insert mode, use ggVGu. 

• gg - Move to the first line of text in the file
• V - Enable visual selection
• G - Move to the last line in the file
• u - Convert everything selected to lowercase

To remove the suspend button:

xfconf-query -c xfce4-session -np '/shutdown/ShowSuspend' -t 'bool' -s 'false'

To remove the hibernate button:

xfconf-query -c xfce4-session -np '/shutdown/ShowHibernate' -t 'bool' -s 'false'

To add the buttons simply changet the boolean value from false to true.

First, create a shell script to generate the output and send it to the console.

mkdir /etc/scripts
cat << EOF > /etc/scripts/ctrl-alt-del.sh 
#!/bin/sh

/bin/echo "" > /dev/console
/bin/echo "Nope. This isn't Windoze." > /dev/console
EOF

 Next, create the two systemd files.

rm -f /lib/systemd/system/ctrl-alt-del.target

1. From Outlook, open your macro editor. (Either press alt-F11 or select Tools, Macro, Visual Basic Editor.)
2. In the macro editor window, select Insert, Module. This will create a text editor window into which you can paste the macro.
3. In the text editor window, paste in the code below. (I recommend you review the code to be sure it's doing what you want.)
4. You can run the code by placing your cursor anywhere in the code window between the "Sub" and "End Sub" statements and pressing F5. Optionally, you can close the Visual Basic window, then select Tools, Macro, Macros..., and "Run" RemoveDuplicateEvents.

The last section of the macro removes all items from your Deleted Items folder. I discovered this is important, because events in my Deleted Items folder "mysteriously" kept re-duplicating. Once I cleaned out the folder, my sync'ing was successful.

Here is the code for the macro. Hopefully, it is useful to someone. Please let me know if you have any problems so I can correct it. Also, I have similar macros to remove duplicate contacts and notes if anyone is interested.

Instructions

1. From Outlook, open your macro editor. (Either press alt-F11 or select Tools, Macro, Visual Basic Editor.)
2. In the macro editor window, select Insert, Module. This will create a text editor window into which you can paste the macro.
3. In the text editor window, paste in the code below. (I recommend you review the code to be sure it’s doing what you want.)
4. You can run the code by placing your cursor anywhere in the code window between the “Sub” and “End Sub” statements and pressing F5. Optionally, you can close the Visual Basic window, then select Tools, Macro, Macros…, and “Run” RemoveDuplicateContacts.

Here is the code for the macro. Hopefully, it is useful to someone. Please let me know if you have any problems so I can correct make an effort to correct the macro.

IMPORTANT A regular copy/paste should work correctly. However, you may experience issues with line breaks that prevent the macro from working. If this is the case, the Outlook VB editor will make it abundantly clear what lines are invalid, so it should be pretty easy to fix rogue line wrapping.

Lookout's normal behavior is to delete calendar invites after accepting or declining them. This reverses that behavior.

Outlook 2010

• File -> Options -> Mail
• Uncheck "Delete meeting requests..." (under "Send messages")

This is useful if you want to send Lookout reminders to your phone via an SMS email gateway.

Create the VB script to do it:

1. Press ALT+F11 to open the VB Window.
2. Double-click Project1, click Microsoft Outlook Object, and click ThisOutlookSession.
3. Enter the code below in the code window, modifying the "To" portion of the message.
4. On the File menu, click Save VbaProject.otm.
5. Close the Visual Basic Editor and quit Outlook.

Make sure the macro can run
Restart Outlook. When prompted with a security warning, click "Enable Macros".

-- or --

Lower your security settings by clicking Tools -> Macros -> Security. Make the
changes and click "OK".

-- or --

(Outlook 2010) From the File menu, go to "Trust Center" then click "Trust Center Settings" and choose "Macros" then enable all macros.

• Install vnc-server

apt-get install tightvncserver

• As the user you want VNC to run as, launch the VNC server manually. This will create the config directory and files, including your password for the VNC session.

vncserver :1

• Create an init script to start VNC as a service at boot (i.e. /etc/scripts/vnc-server)

#!/bin/sh

# The username VNC will run as
export USER="joeblow"

# The display that VNC will use
DISPLAY="1"

# Color depth (value between 8 and 32)
DEPTH="16"

# The Desktop geometry to use.
#GEOMETRY="x"
GEOMETRY="1024x768"

# The name that the VNC Desktop will have.
NAME="vnc-server-1"

OPTIONS="-name ${NAME} -depth ${DEPTH} -geometry ${GEOMETRY} :${DISPLAY}"

case "$1" in
  start)
    echo "Starting vncserver as user '${USER}' on :${DISPLAY}"
    su ${USER} -c "/usr/bin/vncserver ${OPTIONS}"
    ;;
  stop)
    echo "Stoping vncserver as user '${USER}' on :${DISPLAY}"
    su ${USER} -c "/usr/bin/vncserver -kill :${DISPLAY}"
    ;;
  restart)
    $0 stop
    $0 start
    ;;
  *)
    echo "Usage: $0 [start|stop|restart]"
    exit 2
esac

exit 0

• Make the script executable:

chmod +x /etc/scripts/vnc-server

•  Add the script to the rc.local file, above any line that reads "exit 0"

/etc/scripts/vnc-server start

First, install the unattended-upgrades packages:

apt-get -y install unattended-upgrades apt-listchanges
apt-get clean

Next, set any email generated by this to go to root (make sure this is all on one line):

sed -e 's/^\/\/Unattended-Upgrade::Mail "root";/Unattended-Upgrade::Mail "root";/' -i /etc/apt/apt.conf.d/50unattended-upgrades

Then, create the following config file:
