In order to deliver some accounts locally, you can set up virtual aliases as follows:

1. Add the following line to /etc/postfix/main.cf:
virtual_alias_maps = hash:/etc/postfix/virtual
mail_spool_directory=/var/spool/mail

2. Create /etc/postfix/virtual as follows:
root root@localhost

3. postmap /etc/postfix/virtual

4. Restart postfix

Note: Make sure that /etc/aliases doesn’t have root’s mail being redirected

browse to https://clouddns.dcx.rackspace.com/scripts/new

click the command you wish to run to get the exact command

for instance edit mx records uses ‘edit_mx_record zone fqdn priority mail_server’

Change the values by running the following command:

perl -pi -e ‘s/^[0-9]+\s+View\s+(.*?)$/edit_mx_record $1 $1 10 mx1.emailsrvr.com/’ domainlist.txt

This will result in a file with the commands to copy into https://clouddns.dcx.rackspace.com/scripts/new. Change the DDI and hit execute, and you should be golden.

Edit /etc/fail2ban/jail.conf as follows:

action = %(action_)s

gets changed to

action = %(action_mw)s

which causes fail2ban to execute an action shortcut that sends mail:

#########section of jail.conf############################################
# Action shortcuts. To be used to define action parameter

# The simplest action to take: ban only
action_ = %(banaction)s[name=%(__name__)s, port=”%(port)s”, protocol=”%(protocol)s”, chain=”%(chain)s”]

# ban & send an e-mail with whois report to the destemail.
action_mw = %(banaction)s[name=%(__name__)s, port=”%(port)s”, protocol=”%(protocol)s”, chain=”%(chain)s”]
%(mta)s-whois[name=%(__name__)s, dest=”%(destemail)s”, protocol=”%(protocol)s”, chain=”%(chain)s”]

# ban & send an e-mail with whois report and relevant log lines
# to the destemail.
action_mwl = %(banaction)s[name=%(__name__)s, port=”%(port)s”, protocol=”%(protocol)s”, chain=”%(chain)s”]
%(mta)s-whois-lines[name=%(__name__)s, dest=”%(destemail)s”, logpath=%(logpath)s, chain=”%(chain)s”]

# Choose default action. To change, just override value of ‘action’ with the
# interpolation to the chosen action shortcut (e.g. action_mw, action_mwl, etc) in jail.local
# globally (section [DEFAULT]) or per specific section
action = %(action_)s

To change the serverinfo password for munin,

htpasswd /etc/munin/munin-htpasswd serverinfo

The find command is very verstile, and I use it all the time. Here are the parameters that I use most often:
-name <string> Finds files in specified directory whose name matches (case-sensitive) string
-iname <string> Finds files in specified directory whose name matches (case-insensitive) string
-exec Executes a command on the files found (see ls -l example below)
-perm <mode> Finds files in specified directory that match the permission mode
-size Finds files in specified directory
-print Finds the files and prints out the filename. This is useful in a find . -exec grep
-regex<pattern> Finds files in specified directory with name that matches regular expression pattern.
-atime <+-><n> Finds files in specified directory that were accessed less than, more than, or exactly n minutes ago
-amin <+-><n> Finds files in the specified directory that were accessed less than, more than, or exactly n minutes ago
-mmin <+-><n> Finds files in specified directory that were last modified less than, more than, or exactly n minutes ago
-mtime <+-><n> Finds files in specified directory that were last modified less than, more than, or exactly n*24 hours ago
-type <filetype> Find files in the specified directory of type:
b block (buffered) special
c character (unbuffered) special
d directory
p named pipe (FIFO)
f regular file
l symbolic link; this is never true if the -L option
or the -follow option is in effect, unless the
symbolic link is broken. If you want to search for
symbolic links when -L is in effect, use -xtype.
s socket

Examples:
Find files in current directory that end in .txt:
find . -name "*.txt"

Find files in current directory that were created within the last hour:
find . -ctime -60

Find files in current directory not owned by root:
find . \! -user root -print

Find files in current directory with 0777 permissions and chmod them to 644:
find . -type f -perm 0777 -print -exec chmod 644 {} \;

Find files in current directory with owner apache and change to www-data:
find . -user apache -exec chown www-data {} \;

Find all files in current directory that contain string and output their names:
find . -exec grep string {} \; -print

Find files in the current directory with ACLs set:
find . -type f -exec ls -l {} \; | grep -v "\+"

Find files older than 7 days matching string “vicki_test2 and move to new directory
mkdir -p /var/mitto/data/vicki_dir && find /var/mitto/data/ -regextype posix-extended -regex '^.*vicki_test2.*\.[^.]+$' -mtime +7 -exec mv {} /var/mitto/data/vicki_dir \;

One method I have seen programmers (including myself) use to keep folks out of private libraries / include modules is to put a check in there.

Easiest example:

in index.php (or any script with permission to be called directly), this line, immediately after the “
