Setting up dropbox with encryption on ubuntu.

Firstly install drop box: https://www.dropbox.com/install

Now we need to install the encfs.

#apt-get install -y encfs

Now to create an encrypted drive:

#encfs ~/Dropbox/data.encrypt ~/data

Creating new encrypted volume.

Please choose from one of the following options:

enter "x" for expert configuration mode,

enter "p" for pre-configured paranoia mode,

anything else, or an empty line will select standard mode.

?>

Standard configuration selected.

Configuration finished. The filesystem to be created has

the following properties:

Filesystem cipher: "ssl/aes", version 2:2:1

Filename encoding: "nameio/block", version 3:0:1

Key Size: 192 bits

Block Size: 1024 bytes

Each file contains 8 byte header with unique IV data.

Filenames encoded using IV chaining mode.

File holes passed through to ciphertext.

Now you will need to enter a password for your filesystem.

You will need to remember this password, as there is absolutely

no recovery mechanism. However, the password can be changed

later using encfsctl.

New Encfs Password:

Verify Encfs Password:

Now that we have setup the encrypted folder we need to tell Dropbox to not sync the drive settings.

#dropbox exclude add ~/Dropbox/data.encrypt/.encfs6.xml

Excluded:

~/Dropbox/data.encrypt/.encfs6.xml

Now to get this to mount when you login. First install libpam-encfs:

#apt-get install libpam-encfs

Edit /etc/fuse.conf and add:

user_allow_other

Edit /etc/security/pam_encfs.conf

drop_permissions

encfs_default

* /home/$USER/Dropbox/data.encrypt /home/$USER/data -v allow_other

Edit /etc/pam.d/common-auth to look like:

auth sufficient pam_encfs.so

auth [success=2 default=ignore] pam_unix.so nullok_secure use_first_pass

auth [success=1 default=ignore] pam_winbind.so krb5_auth krb5_ccache_type=FILE cached_login try_first_pass

auth requisite pam_deny.so

auth required pam_permit.so

And your done, Enjoy.

Zabbix SMS queuing.

I had a problem with the sms program we use just dropping sms's if you tried to send too many at one time.

I'm using the following script in zabbix to interface with gammu the sms tool.

#!/usr/bin/env bash

LOCKFILE=/tmp/sms.lock

LOCKED="false"

echo "waiting for lock" |logger -t "sms" -i -p local3.info

while [ "${LOCKED}" = "false" ]

do

if [ ! -f ${LOCKFILE} ]; then

echo "$$" > ${LOCKFILE}

fi

if [ "$$" = "`cat ${LOCKFILE}`" ]; then

LOCKED="true"

fi

done

echo "got lock." |logger -t "sms" -i -p local3.info

trap "{ rm -f $LOCKFILE ; exit 255; }" EXIT

echo "sending sms to: $1" |logger -t "sms" -i -p local3.info

echo "$2 $3 $4 $5 $6 $7 $8 $9" | /usr/bin/gammu sendsms TEXT $1 > /dev/null 2>&1

exit 0

Maybe someone else will find this useful.
