Create a USER Account with ROOT Privileges
Use the following commands to create the new user dennis, grant him the same privileges as root and set him a password : # useradd -ou 0 -g 0 dennis # passwd dennis Perhaps you already have some user dennis and you would like to give root permissions to a normal user. # grep dennis /etc/passwd dennis:x:1001:1001::/home/dennis:/bin/sh Edit /etc/passwd file and grant root permissions to the user dennis by changing User and Group IDs to UID 0 and GID 0 : # $ grep dennis /etc/passwd dennis:x:0:0::/home/dennis:/bin/sh You won't be able to delete second root user with another UID 0 using userdel command. # userdel dennis userdel: user dennis is currently used by process 1 To delete user dennis with UID 0, open /etc/passwd file and change dennis's UID. For example, change the line : dennis:x:0:0::/home/dennis:/bin/sh to dennis:x:1111:0::/home/dennis:/bin/sh Now, you'll be able to delete user dennis with userdel command (as shown above)

Configuring an NTP Server and Peer
How to configure an NTP server and peer. BEFORE YOU BEGIN Make sure that you are in the correct VDC. To change the VDC, use the switchto vdc command. Make sure you know the IP address or DNS names of your NTP server and its peers. If you plan to use CFS to distribute your NTP configuration to other devices, then you should have already completed the following: –Enabled CFS distribution using the "Configuring CFS Distribution" section. –Enabled CFS for NTP using the "Enabling CFS Distribution for NTP" section. SUMMARY STEPS 1. config t 2. [no] ntp server {ip-address | ipv6-address | dns-name} [key key-id] [maxpoll max-poll] [minpoll min-poll] [prefer] [use-vrf vrf-name] 3. [no] ntp peer {ip-address | ipv6-address | dns-name} [key key-id] [maxpoll max-poll] [minpoll min-poll] [prefer] [use-vrf vrf-name] 4. (Optional) show ntp peers 5. (Optional) copy running-config startup-config DETAILED STEPS Step 1 config t Example: switch# config t Enter configuration commands, one per line. End with CNTL/Z. switch(config)# Places you in global configuration mode. Step 2 [no] ntp server {ip-address | ipv6-address | dns-name} [key key-id] [maxpoll max-poll] [minpoll min-poll] [prefer] [use-vrf vrf-name] Example: switch(config)# ntp server 192.0.2.10 Forms an association with a server. Use the key keyword to configure a key to be used while communicating with the NTP server. The range for the key-id argument is from 1 to 65535. Use the maxpoll and minpoll keywords to configure the maximum and minimum intervals in which to poll a peer. The range for the max-poll and min-poll arguments is from 4 to 16 seconds, and the default values are 6 and 4, respectively. Use the prefer keyword to make this the preferred NTP server for the device. Use the use-vrf keyword to configure the NTP server to communicate over the specified VRF. The vrf-name argument can be default, management, or any case-sensitive alphanumeric string up to 32 characters. Note If you configure a key to be used while communicating with the NTP server, make sure that the key exists as a trusted key on the device. For more information on trusted keys, see the "Configuring NTP Authentication" section. Step 3 [no] ntp peer {ip-address | ipv6-address | dns-name} [key key-id] [maxpoll max-poll] [minpoll min-poll] [prefer] [use-vrf vrf-name] Example: switch(config)# ntp peer 2001:0db8::4101 Forms an association with a peer. You can specify multiple peer associations. Use the key keyword to configure a key to be used while communicating with the NTP peer. The range for the key-id argument is from 1 to 65535. Use the maxpoll and minpoll keywords to configure the maximum and minimum intervals in which to poll a peer. The range for the max-poll and min-poll arguments is from 4 to 17 seconds, and the default values are 6 and 4, respectively. Use the prefer keyword to make this the preferred NTP peer for the device. Use the use-vrf keyword to configure the NTP peer to communicate over the specified VRF. The vrf-name argument can be default, management, or any case-sensitive alphanumeric string up to 32 characters. Step 4 show ntp peers Example: switch(config)# show ntp peers (Optional) Displays the configured server and peers. Note A domain name is resolved only when you have a DNS server configured. Step 5 copy running-config startup-config Example: switch(config)# copy running-config startup-config (Optional) Saves the change persistently through reboots and restarts by copying the running configuration to the startup configuration. This example shows how to configure an NTP server and peer: switch# config t Enter configuration commands, one per line. End with CNTL/Z. switch(config)# ntp server 192.0.2.10 key 10 use-vrf Red switch(config)# ntp peer 2001:0db8::4101 prefer use-vrf Red switch(config)# show ntp peers -------------------------------------------------- Peer IP Address Serv/Peer -------------------------------------------------- 2001:0db8::4101 Peer (configured) 192.0.2.10 Server (configured) switch(config)# copy running-config startup-config 100% switch(config)#

Drupal Updates not working
I'm behind a proxy which I believe is the reason I can't get through.... at least that's what I thought. I entered the proxy settings in /var/www/oa/sites/default/settings.php still no luck Then I realized that by running sestatus it shows it is enforced and probably blocking port 8080 which is where the proxy is so I changed sestatus to disabled by editing the following and rebooting the system /etc/sysconfig/selinux still no luck Still checking

Open Atrium Missing Icons
For some reason, shortly after I got clean URL's to work some of my icons disappeared and instead showed some garbage like the screenshot below. What I did first was clear the cache in my browser and even tried a different browser on a different machine... no luck Next I tried clearing the cache on Open Atrium... no luck Within the theme I clicked on Scan for breakpoints... no luck Then I switched from the default theme to something else as default then back to the original theme... FIXED

piix4_smbus controller not enabled ERROR
Running CentOS 7 in VMware Workstation on my Windows 7 HP ProBook 6460b During bootup I am getting the following error and it's driving me nuts. piix4_smbus 0000:00:007.3: Host SMBus controller not enabled! I ran lspci -v (after installing it using: yum -y install pciutils) Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 08) Subsystem : VMware Virtual Machine Chipset Flags: medium devsel, IRQ 9 Everything I read said just to add blacklist i2c_piix4 to the bottom of the file /etc/modprobe.d/blacklist.conf which got rid of the message (NOTE: this file didn't exist and only has this one entry)

How to integrate Drupal and Alfresco
Drupal is an excellent CMS used on millions of websites but it has always lacked a decent Document Management module. This is where Alfresco comes in which is an excellent Document Management Repository but lacks any luster of a website. These two together would prove to be a great pair / team. Here are some sites that talk about methods to integrate the two of these together. CMIS Liferay (still uses CMIS but some great information)

NNMi Tips
What is NNMi (NETWORK NODE MANAGER i)? Unify fault, availability, and performance monitoring. This network management software helps you improve network uptime and performance, and increase responsiveness to business needs. Note: hostnames in NNMi must match what is in DNS (very case sensative)

How to Install Alfresco Notes
Here are some notes on how I install Alfresco on a CentOS 7.x Download from Alfresco I had a big issue trying to get this to load without a GUI. I loaded GNOME Classic desktop, opened terminal up, entered sudo su - to become root. Then I moved the .bin file to /tmp. Then I ran chmod +x alfresco-community-5.0.c-installer-linux-x64.bin then I ran ./alfresco-community-5.0.c-installer-linux-x64.bin To reach the site on port 8080 I had to edit iptables to allow port 8080 -A INPUT -p tcp -m state --state NEW -m tcp --dport 8080 -j ACCEPT Restart iptables /etc/init.d/iptables restart

I was complaining on Twitter on how awful bluehost was for taking 48 hours to restore my sites in which time I lost my google rankings since they couldn't contact my site. Wirenine saw my issues with Bluehost and offered there services. I looked into them but they were definitly more expensive than anyone else but had a crap load more features. I decided to go with Dreamhost because of cost and after learning they aren't very technical or nice, I decided to give wirenine a shot. They transferred all my data over with some issues because of what Bluehost does with your sites but wirenine figured them out quickly and never did they show any attitude. So far, very impressed with the support staff. I will say, if you aren't familar with WHM like I'm not, then a huge learning curve if you go with the VPS option like I did. Many advanced features and configurations available to you. Way Way WAY more than any of the other VPS solutions I have tried. I do recommend wirenine and they are U.S. based.

Just okay
I tried to switch my VPS from Bluehost to Dreamhost since Dreamhost is NOT part of the EIG. I like the interface even though its not cPanel but its pretty easy to use. Had some issues where all 8 of my sites wouldn't let me log in (note these sites include IP.Board, Joomla and Drupal mainly) and so I contacted Dreamhost support and they insisted the issue is with the software not the server. I explained to them that these are just transfers and they work without issue on Bluehost and still they insisted its not the server. So I contacted Invision Power (makers of the IP.Board you are reading this on) and they checked it out and uploaded a stand alone script which also would not allow you to log in. So I contacted Dreamhost support again and they basically said, too bad. I still have a few domains on this site but I'm not putting anything important with Dreamhost if they have such horrible support.

Crappy Bluehost
So I signed up in August 2014 for a Bluehost VPS since I had so many issues with inmotionhosting that I figured Bluehost is a pretty popular and well known site but I realized later its not because they have great service but more because they are so cheap. The implemented a change on a RAID controller on the VPS I was part of (without notifying us of this change) and it killed the controller. They had to rebuild all of our data and it took 48 hours to do this. Support was useless and no remorse but why would they care. Bluehost is part of the Endurance International Group (EIG) which these are also: 2slick.com AccountSupport Arvixe LLC A Small Orange ApolloHosting Berry Information Systems L.L.C.

Error: Could not load template
Are you trying to figure out why you might be getting the error Error: Could not load template 'feed__generic_12' from group '' It appears you may have been looking at one of the Blocks in IP.Content and somehow just looking at it may have changed something. For me it was on the Home Page or Front Page and the error mentions feed and I know normally that this spot it should be the Forum Recent Topics. So I went to that block and clicked Edit.. under the Template tab it showed nothing for a preview so I knew that was an issue. I selected News Feed and it showed a preview so I clicked save and my error went away.
