Resetting Wordpress Password

Get an MD5 hash of your password.)Visit md5 Hash Generator, or...http://www.miraclesalad.com/
Create a key with Python. or...
On Unix/Linux:Create file wp.txt with the new password in it (and *nothing* else)
md5sum wp.txt
rm wp.txt
"mysql -u root -p" (log in to MySQL
enter your mysql password
"use (name-of-database)" (select WordPress database)
"show tables;" (you're looking for a table name with "users" at the end)
"SELECT ID, user_login, user_pass FROM (name-of-table-you-found)" (this gives you an idea of what's going on inside)
"UPDATE (name-of-table-you-found) SET user_pass="(MD5-string-you-made)" WHERE ID = (id#-of-account-you-are-reseting-password-for)" (actually changes the password)
"SELECT ID, user_login, user_pass FROM (name-of-table-you-found)" (confirm that it was changed)
(type Control-D, to exit mysql client)
Note if you have a recent version of MySQL (version 5.x?) you can have MySQL compute the MD5 hash for you.
Skip step 1. above.
Do the following for step 7. instead.
"UPDATE (name-of-table-you-found) SET user_pass = MD5('"(new-password)"') WHERE ID = (id#-of-account-you-are-reseting-password-for)" (actually changes the password)
Note that even if the passwords are salted, meaning they look like $P$BLDJMdyBwegaCLE0GeDiGtC/mqXLzB0, you can still replace the password with an MD5 hash, and Wordpress will let you log in.

Find spamming account in Postfix or Plesk

Queue Counting
The following command provides a sorted list of the accounts that have the most mail in the queue. This usually means a maximum of 2 or 3 spammers at the end of the list:

mailq|grep ^[A-F0-9]|cut -c 42-80|sort |uniq -c|sort -n|tail

grep “status=sent” /var/log/maillog |cut -d “=” -f 2 |cut -d “>” -f 1 |cut -d “<” -f 2 |sort -n |uniq -c

grep “dovecot” /var/log/maillog |grep “Aborted login” |cut -d “,” -f 3 |cut -d “:” -f 4 |sort -n |uniq -c

Making the CSF temporary block permanent

Temporary to Permanent IP blocking. The following enables this feature to
# permanently block IP addresses that have been temporarily blocked more than
# LF_PERMBLOCK_COUNT times in the last LF_PERMBLOCK_INTERVAL seconds. Set
# LF_PERMBLOCK to "1" to enable this feature
#
# Care needs to be taken when setting LF_PERMBLOCK_INTERVAL as it needs to be
# at least LF_PERMBLOCK_COUNT multiplied by the longest temporary time setting
# (TTL) for blocked IPs, to be effective
#
# Set LF_PERMBLOCK to "0" to disable this feature

LF_PERMBLOCK =  Default: 1 [0-1]

LF_PERMBLOCK_INTERVAL =  Default: 86400 [3600-604800]

LF_PERMBLOCK_COUNT =  Default: 4 [1-20]

LF_PERMBLOCK_ALERT =  Default: 1 [0-1]

# Permanently block IPs by network class. The following enables this feature
# to permanently block classes of IP address where individual IP addresses
# within the same class LF_NETBLOCK_CLASS have already been blocked more than
# LF_NETBLOCK_COUNT times in the last LF_NETBLOCK_INTERVAL seconds. Set
# LF_NETBLOCK to "1" to enable this feature
#
# This can be an affective way of blocking DDOS attacks launched from within
# the same networ class
#
# Valid settings for LF_NETBLOCK_CLASS are "A", "B" and "C", care and
# consideration is required when blocking network classes A or B
#
# Set LF_NETBLOCK to "0" to disable this feature

LF_NETBLOCK =  Default: 0 [0-1]

LF_NETBLOCK_INTERVAL =  Default: 86400 [3600-604800]

LF_NETBLOCK_COUNT =  Default: 4 [1-20]

LF_NETBLOCK_CLASS =  Default: C [A or B or C]

LF_NETBLOCK_ALERT =  Default: 1 [0-1]

SCP in detail

Example syntax for Secure Copy (scp)

What is Secure Copy?

scp allows files to be copied to, from, or between different hosts. It uses ssh for data transfer and provides the same authentication and same level of security as ssh.

Examples

Copy the file "foobar.txt" from a remote host to the local host

$ scp your_username@remotehost.edu:foobar.txt /some/local/directory

Copy the file "foobar.txt" from the local host to a remote host

$ scp foobar.txt your_username@remotehost.edu:/some/remote/directory

Copy the directory "foo" from the local host to a remote host's directory "bar"

$ scp -r foo your_username@remotehost.edu:/some/remote/directory/bar

Copy the file "foobar.txt" from remote host "rh1.edu" to remote host "rh2.edu"

$ scp your_username@rh1.edu:/some/remote/directory/foobar.txt \ your_username@rh2.edu:/some/remote/directory/

Copying the files "foo.txt" and "bar.txt" from the local host to your home directory on the remote host

$ scp foo.txt bar.txt your_username@remotehost.edu:~

Copy the file "foobar.txt" from the local host to a remote host using port 2264

$ scp -P 2264 foobar.txt your_username@remotehost.edu:/some/remote/directory

Copy multiple files from the remote host to your current directory on the local host

$ scp your_username@remotehost.edu:/some/remote/directory/\{a,b,c\} .

$ scp your_username@remotehost.edu:~/\{foo.txt,bar.txt\} .

scp Performance

By default scp uses the Triple-DES cipher to encrypt the data being sent. Using the Blowfish cipher has been shown to increase speed. This can be done by using option -c blowfish in the command line.

$ scp -c blowfish some_file your_username@remotehost.edu:~

It is often suggested that the -C option for compression should also be used to increase speed. The effect of compression, however, will only significantly increase speed if your connection is very slow. Otherwise it may just be adding extra burden to the CPU. An example of using blowfish and compression:

$ scp -c blowfish -C local_file your_username@remotehost.edu:~

How do I turn on/off mod_userdir on my cPanel/WHM server?

Apache's mod_userdir allows users to view their sites by entering a tilde(~) and their username as the uri on a specific host. For example http://test.cpanel.net/~fred/ will bring up the user fred's domain. The disadvantage of this feature is that any bandwidth usage used by this site will be put on the domain it is accessed under (in this case test.cpanel.net). mod_userdir protection prevents this from happening. You may however want to disable it on specific virtual hosts (generally shared ssl hosts.)

First you'll need to login to WHM for your server, http://serversip/whm (serversip being the ip address of your dedicated server or vps).

Once you are logged into WHM, you will want to browse over to the following path:

Main >> Security Center >> Apache mod_userdir Tweak

From there, you can select which accounts you want to enable for mod_userdir
