b) After the installation is done, you can optionally add an external hard drive to make it easier to move your data. We'll be using a service called "autofs" to automatically detect your hard drive and make it ready to share on the network each time you plug it in. To install autofs, use this command:
sudo apt-get install autofs
Once that finishes, you'll want to connect your external hard drive and find out what device Ubuntu assigns it. After plugging in the hard drive wait a few seconds and then enter this command:
dmesg | tail
You should see something very similar to this:
[47820.164000] sdb: Write Protect is off
[47820.164000] sdb: Mode Sense: 03 00 00 00
[47820.164000] sdb: assuming drive cache: write through
[47820.164000] SCSI device sdb: 398297088 512-byte hdwr sectors (203928 MB)
[47820.168000] sdb: Write Protect is off
[47820.168000] sdb: Mode Sense: 03 00 00 00
[47820.168000] sdb: assuming drive cache: write through

[47820.184000] sd 4:0:0:0: Attached scsi generic sg2 type 0
The line "[47820.168000] sdb: sdb1" is what you'll want to pay attention to. This tells us that Ubuntu is assigning the device to "sdb", and it's partition is labeled as "sdb1". "1" being the first and only partition on the disk. Next, we'll what to find out what kind of partition is on the disk. Enter this into the console:
sudo fdisk -l /dev/sdb
The "System" column will display what kind of partition it is. Take note on what type of partition it is for the following instructions. If it's "HPFS/NTFS", you'll want to use the "ntfs-3g" driver. If it contains "FAT", you'll use the "vfat" driver. Finally, if it's "Linux", you can just use the "auto" driver. Note, if it is a NTFS partition, you will have to manually install the new NTFS read/write drivers by using:
sudo apt-get install ntfs-3g
Next, we'll want to add this information to the autofs service. Use to following command to edit to autofs master configuration file:
sudo nano /etc/auto.master
Note: You can replace "nano" with your preferred text editor. To save a file in nano, use the keyboard shortcut Ctrl+O. To exit, press Ctrl+X.
Now, find the line containing:
#/misc /etc/auto.misc
Change it to:
/misc /etc/auto.misc --timeout=60
Save it and edit the autofs "miscellaneous" configuration file next by entering this command:
sudo nano /etc/auto.misc
Add this to the bottom of the file:
external -fstype=ntfs-3g :/dev/sdb1
Remember to replace "ntfs-3g" with the type of driver you found earlier in this section. Note, if you are using "ntfs-3g", you might want to append ",force" , making it "-fstype=ntfs-3g,force". This makes it easier to use uncleanly unmounted drives. This maybe a little risky, but it makes it so much easier to troubleshoot.
Finally, restart the autofs service:
sudo /etc/init.d/autofs restart
Now, every time anything tries to find files in the "/misc/external" directory, Ubuntu will attempt to automatically mount that drive to be used.
Add DynDNS to your router (if your router does not support DynDNS, good luck wit the http://en.wikipedia.org/wiki/DD-WRT fimrware) so you can access your network from outside, even if your provider changes the IP.

Note, this error also sometimes occurs if you have an old shared memory segment lying around from a previous run that is too small. Use the ipcs and ipcrm system commands to check and remove it if necessary.'"
You can often find out how much shared memory is available by typing the following :-
cat /proc/sys/kernel/shmall
and the most you can allocate in one go :-
cat /proc/sys/kernel/shmmax
To change these values type (for example) :-
echo 134217728 >/proc/sys/kernel/shmall
echo 134217728 >/proc/sys/kernel/shmmax
Be sure to restart ZoneMinder after this.However be aware that sometimes you will only need to change the shmmax value as shmall is often large enough. Also changing these values in this way is only effective until your machine is rebooted.
To change them permanently you will need to edit /etc/sysctl.conf and add the following lines (for example) :-
kernel.shmall = 134217728
kernel.shmmax = 134217728
To load these settings in the sysctl.conf file type:
sysctl -p
To check your shared memory settings type:
ipcs -l
These changes will now also be set the next time your machine is restarted.
