Dell iDRAC racadm issue

Happen to came across this problem. It does not happen to my other units of Dell Servers doing the same deployment procedure.

Take note that you need to purchase Dell DRAC Enterprise in order to execute ‘racadm’

[root@server ~]# racadm getled
This Integrated Dell Remote Access Controller does not support RACADM commands.
Please contact Dell Customer Service to upgrade your version of iDRAC.

Strangely, this should not happen to me as I have purchased Dell DRAC Enterprise. This did not happen to my previous unit of Dell Servers.

After much troubleshooting and pulling of my hair, I managed to locate the problem to this 2 specific package not installed by OMSA

yum install srvadmin-idrac7 srvadmin-idracadm7

After which, let’s try to execute the command again

[root@server ~]# racadm getled
LED State :    Not-Blinking

Looks good 🙂 Hope it helps!

Changing of Hosts file to test website before real migration

Take note, you need to have administrative rights before you can edit the hosts file

Usually when you do website migration, you want to test the website in the new server before you point your live traffic over. There is a few methods is doing so but changing your host file will be the best option as it will allows you to do REAL testing

1) You need to run Notepad as a administrative rights

2) After which, go to “File” -> “Open” and key in “%systemroot%\system32\drivers\etc\hosts” (without quotes) under the “File Name”

3) You will need to add an entry like this at the end of the file.

You need to replace “x.x.x.x” with your new server IP address and “” with your real domain name that you are testing on

4) You will then need to close your browser, and flush the dns cache on your computer.

5) Now, try to ping your “” and you should see the new IP address

Hope this helps!

OpenX permission issue

Everytime when I login to my openx installation, I had this error message

chmod -R a+w /home/openx/var/cache/
chmod -R a+w /home/openx/www/images/


Passive FTP in Windows 2003

A quick command to enable passive FTP

Simply put, it is opening a hole in the firewall to allow passive connections to go through. You might want to google more to learn more about it. This is just a quick command to do it.

I have specific port 5500 to 5520 for this. You might need to restart the server to ensure everything is working.

cd "C:\Inetpub\AdminScripts"
adsutil.vbs set /MSFTPSVC/PassivePortRange "5500-5520"
FOR /L %I IN (5500,1,5520) DO netsh firewall add portopening TCP %I "Passive FTP"%I 
net stop msftpsvc
net start msftpsvc

Hope it helps.

Dell LCD Custom Text

Recently I had setup a HA-pair in my environment and if I do not have my computer with me, I need the NOC guys to be able to identify which is the ‘active’ unit and I found out that writing custom text to Dell LCD panel is pretty easy after some digging.

If you have not installed OMSA, please go to this link and follow the instructions.

Next, install the IMPI tool for you to be able to read/write to the LCD panel

yum install -y OpenIPMI-tools

You just need to know 2 commands to read/write to the LCD.

To see your current content on the LCD panel

ipmitool delloem lcd info

To write your custom text to the LCD panel

ipmitool delloem lcd set mode userdefined MyCustomText

There you go, it’s so simple.

Hope someone find this useful =)

The terminal server has exceeded the maximum number of allowed connections

Encountered this problem with one of my customer’s server. A quick fix will be logging in remotely using console session to clear up the connections

mstsc /v: /admin

Replace ‘’ with your server IP.

After which, you can launch the Terminal Server Manager (Start -> Run -> tsadmin.exe) and clear up the sessions.

Hope this helps…
