How to remove the chrome bell in the notification tray icon

Well this is annoying! It used to be removed via: chrome://flags/ and then just disabling “Enable Rich Notifications Mac, Windows”, but now it is: “Notification Center behavior Mac”. You also have to leave the setting to DEFAULT, and not disabled. Then relaunch and it’s gone.

We shall see what it takes on the next go around to disable it. OY Google, please stop. Just make it the same option every time. This is current as of: Version 36.0.1985.143

Centos 6 multiple vlans with one eth device

UPDATED for CentOS 7:

CentOS 7 multiple VLANs on one interface

The scenario I had was 1 eth0 device, and my port trunk’d to allow 9 and 10 vlans. I wanted to assign the full /24 to this box, using only eth0 and the trunk port in CentOS 6. This is what I had to do.

in linux NEED eth0 and one VLAN’d CFG:

cd /etc/sysconfig/network-scripts/

ifcfg-eth0.9 the .9 is the vlan

# Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express
DEVICE=eth0.9
BOOTPROTO=none
HWADDR=00:1d:xx:xx:xx:xx
ONBOOT=yes
TYPE=Ethernet
IPADDR=173.243.116.2
NETMASK=255.255.255.0
VLAN=yes

ifcfg-eth0.10

# Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express
DEVICE=eth0.10
BOOTPROTO=none
HWADDR=00:1d:xx:xx:xx:xx
ONBOOT=yes
TYPE=Ethernet
IPADDR=173.243.117.2
NETMASK=255.255.255.0
VLAN=yes

ifcfg-eth0
# Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:1d:xx:xx:xx:xx
ONBOOT=yes
TYPE=Ethernet

ifcfg-eth0.9-range0
IPADDR_START=173.243.116.3
IPADDR_END=173.243.116.254
NETMASK=255.255.255.0
CLONENUM_START=3

ifcfg-eth0.11-range0
IPADDR_START=199.96.80.3
IPADDR_END=199.96.80.254
NETMASK=255.255.255.0
CLONENUM_START=257

******************************************************************************************

CENTOS 6 REQUIRES NO GATEWAY in ifcfg-eth0.xx so remove it

CENTOS 6 REQUIRES ROUTES ADDED:

You can do this to test, as once the server is rebooted, or network restarted these rules drop:
ip route add default via 192.119.164.1 dev eth0.8 table 1
ip route add default via 192.119.165.1 dev eth0.9 table 2
ip rule add from 192.119.164.2 tab 1 priority 500
ip rule add from 192.119.165.2 tab 2 priority 501
ip rule add from 192.119.164.0/24 table 1
ip rule add from 192.119.165.0/24 table 2

To make it permanent:
cd /etc/sysconfig/network-scripts/

echo ‘default via 192.119.169.1 dev eth0.3 table 1’ > route-eth0.3
echo ‘default via 192.119.174.1 dev eth0.6 table 2’ > route-eth0.6
echo ‘from 192.119.169.2 tab 1 priority 500’ > rule-eth0.3
echo ‘from 192.119.174.2 tab 2 priority 501’ > rule-eth0.6
echo ‘from 192.119.169.0/24 table 1’ > rule-eth0.3
echo ‘from 192.119.174.0/24 table 2’ > rule-eth0.6

history command with timestamp linux

I always find it easier when my history has a time stamp, you can coorolate a lot of things, like last, start/stops of services, who done it, etc.

export HISTTIMEFORMAT=”%F %T ”

This will work for the session, but if you want it saved for every log in add to respective bash_profile:
~/.bash_profile or /root/.bash_profile

Firewall Status: Enabled but Stopped in CSF with cPanel

I kept getting: Firewall Status: Enabled but Stopped in my CSF in cPanel. I am currently running WHM 11.40.1 (build 11) and csf v7.03.

I tried just clicking start, no luck it would just flip back a few minutes later. So I ended up dropping to shell and running

service csf stop
iptables –flush
service csf start

that seemed to work, there must have been a hung iptables rule, or a bad rule that caused CSF to flip to disabled.

error when copying or overwriting the same directory name linux

my directory structure in linux – centos:

/home/html/prod/wordpress/update/
/home/html/prod/wordpress/

/wordpress/ is my wordpress install, and /update/ is my unziped download files and directories.

The errors I kept getting when trying to move or copy the entire directory while sitting in /home/html/prod/wordpress/update/ was:

mv: cannot move `wp-admin’ to a subdirectory of itself, `../wp-admin’
mv: cannot move `wp-content’ to a subdirectory of itself, `../wp-content’

cp: omitting directory `wp-admin’
cp: omitting directory `wp-content’

what I ended up doing was staying in the same directory ( /home/html/prod/wordpress/update ) and running:

cp -fR * ../

f = force
R = recursive

all went well, replaced the entire directory like I wanted and I just removed the /update directory and done.

how to disable RHN in linux – red hat or centos

What I did to disable it was go to: /etc/sysconfig/rhn

and delete all of the files in it. If you want to re-enabled it after, you can just copy the files back, so you may want to copy them to a location you want to keep them at.

removing the limit of 100 rows in squirrel

Using the squirrel app: http://www.squirrelsql.org/ I had issues with only seeing 100 rows in a table. I fixed this by going to File -> New Sessions Properties -> Object Tree -> Contents -> limit rows. The default is 100, but you can uncheck it and you should be good.

If not, you can also do the same under New Sessions Properties -> SQL -> SQL Results – limit rows. Then uncheck it and hit OK.

That worked for me!

I couldn’t get alt f4 working on any of my apps on my new microsoft surface pro with type keyboard 2. It ended up being that my function lock was set! I had to unlock that via: function + caps lock (Thanks rsutoratosu on Anandtech). And now ALT F4 works, time to go kill some apps!

bitfeniex prodigy with 7 hard drives

I bought this bitfenix prodigy case for about $30 off craiglist, someone didn’t like that it was white, and for $30, couldn’t be beat for this case. As it was retailing for about $80 at newegg/microcenter. I was going to build my girlfriend a new PC and thought ITX was the way to go, after building my own gaming rig on ITX, but using an SG05 ( linky to build ). We went to go look at some monitors at mirceoter, and ended up coming up with a sweet touch screen Dell for her. Nice and neat, and it saved us $1500 from buying an imac, LOL!

So what to do with this case, well, my current NAS was about 3~ years old, had about 2TBx7 HDD’s, and was running JBOD, so nothing fancy. It was a neat little water cooling server in an Antec 300, but I wanted to do something different. I actually had 7 WD 2TB RE4’s laying around not doing anything, so I thought lets build an awesome ITX NAS box! So here we are, throwing together a 7 HDD + 1 SSD NAS box running Windows 7.

I love building PC’s, and I love the fact I do it without cutting, or modding (maybe someday i’ll cut and mod), but I like to keep things stock as possible.

I purchased:

Adapec 5805 off ebay for $100, which has 2 8087’s internal, so I could use 2 fanouts for at least 8 drives. It also has 512MB of onboard memory for the raid 5 I wanted to do. Kicker was it came with a working BBU!

I also snagged a 150mm PSU that I read would fit nicely: Seasonic 360W 80PLUS Gold ATX12V Power Supply SSR-360GP
I got a Intel Pentium Processor G3220, nothing fancy, but it is a slight upgrade to my Q9550 that the server is currently running. No worries though, as I need ZERO cpu to RDP and just make sure everything is hunky dory.
I got a ASRock H81M-ITX, which is my first ASRock mobo, so far so good running this thing.
Couple with 4GBx2 DDR3 I had to purchase as well.

So far i’ll be using the intel CPU cooler, and might swap it out for something decent if I find this thing’s too loud.

I got some molex to SATA power adapters, as the PSU only came with 5 SATA power connectors. I also got some 8087 fanout cables I did not have, ran about $15 bucks for the 2 8087’s, and $10 for the 2x molex to sata connectors.

Swapped out the stock bitfenix brushless fans (model BFF-SCF-12025KK-RP) for my scythe SFLEX SFF21G’s hooked up to some devolts to 9v, so they’re nice and silent. I also purchased a nice bitfenix spectre 230mm fan, threw it up front to see it push some air. If this does not work, i’ll grab a 140mm or 120mm scythe i’ve got laying around and use that. I don’t need a LOT of airflow, but the more I can get while keeping silence would be great.

Here’s what 5 of my 6 drives look like … the SSD and other 2TB are in the 5.25″ bay.

I had one problem where I realized the 8087 connectors are a little tight … so I am not snapping in the 3 bay disk set as to not stress the card. This is what it looks like snapped in/stressed:

This is how i’ll leave it:
