EMC ESRSve admin password reset (VXRail Edition)

Resetting a password on a ESRS appliance is pretty straight forward. But there is a pesky error that can pop up from time to time with ESRS appliances that get deployed via the VXRail deployment.

The normal esrs admin password reset goes something like this:


ESRSapplicance:~ # cd /opt/esrs/webuimgmt-util/
ESRSapplicance:~ # ./passwordAdmin.sh

Normally this would then ask you for a new password for the admin account associated with your ESRS appliance.

But what is the error you might ask? Well it happens in lieu of asking for a new password.

“User Configuration File Missing. Please contact ESRS Support”

In order to get around this error it is a simple command you must run before starting the ./passwordadmin.sh script:


ESRSapplicance:~ # echo admin > /etc/esrsadmin.conf
ESRSapplicance:~ # cd /opt/esrs/webuimgmt-util/
ESRSapplicance:~ # ./passwordAdmin.sh

And thats it! Have fun with ESRS and let me know it this article helped you!

AppVol: Capture Machine boots to AppStack VMDK instead of OS

Been running to issues when provisioning Application stacks that the capture machine boots to the the AppStack VMDK instead of the OS VMDK . It is an annoying issue but a very easy fix!

  1. Shutdown the capture machine and take a snapshot.
  2. Edit the settings of the capture machine, change the primary hard drive to SCSI (0:0) under the Virtual Device Node option.
  3. Select the VM options tab > boot options > Force Bios Setup
  4. During the bios setup navigate to boot and ensure the harddrive is first in the boot order.
  5. Restart your capture VM and try to mount the appStack for provisioning.

 

 

RHEL/CentOS7 xrdp auto disconnects when logging on

So I ran into an issue this week with XRDP disconnecting from my RHEL/CentOS7 RDP connection the moment the logon process is finished. Searching around for different answers to this solution there seems to be no one way of doing it. So I decided to tell you what I did to fix the issue and hopefully help you avoid a major headache in the future.

 

I will start with the installation of XRDP and go through the changes.

  1. Install xrdp tigervnc-server on your RHEL/CentOS7 box
yum -y install xrdp tigervnc-server

2. Start xrdp service and enable at boot

systemctl enable xrdp
user@computer:$ systemctl start xrdp

3. Allow 3389 through the firewall and reload firewall

firewall-cmd --permanent --zone=public --add-port=3389/tcp 
user@computer:$ firewall-cmd --reload

4. Configure SELinux ( I did not need to perform this step)

chcon --type=bin_t /usr/bin/xrdp
user@computer:$ chcon --type=bin_t /usr/bin/xrdp-sesman

5. Edit the xrdp.ini file located at the /etc/xrdp/xrdp.ini

vi /etx/xrdp/xrdp.ini

6. Comment out the line that says “Channel_code=1” Here is a example of the .ini file after the change is made

[globals]
bitmap_cache=yes
bitmap_compression=yes
port=3389
crypt_level=high
#channel_code=1
max_bpp=24
#black=000000
#grey=d6d3ce
#dark_grey=808080
#blue=08246b
#dark_blue=08246b
#white=ffffff
#red=ff0000
#green=00ff00
#background=626c72

[xrdp1]
name=sesman-Xvnc
lib=libvnc.so
username=ask
password=ask
ip=127.0.0.1

Just a FYI also some of these commands I did not come up with and where figured out from other blogs. Which when I get permission from the owners I will post here.

That being said this is my first post into some real enterprise level Linux! If you have any tip or tricks as i go down the RHEL CentOS path let me know!

Knowing Stagnation Part 1

When you start at a new company you can tell pretty quickly who is taking a deep investment in their career and future versus who is just riding the creek of stagnation waiting for that gust of wind to get them to pay-day. The signs are clear from the outside looking in, But when you are the one who is stagnant do you know?

One of the biggest mistakes an IT lady/gentleman can make is not knowing when they are stagnant. We all got into IT for the love of learning and the constant challenge,  stagnation is usually looked over and not addressed when it should be. Which can really harm your career and performance at any company. No one is immune to stagnation. The best IT people i know have had a few lulls in their career from time to time. But the question is do they notice it and re mediate?

So how do we find/treat/cure stagnation? Well it’s not easy but we can certainly give it a go.


So how do we know the signs of stagnation?

Don’t want to go to work?

Dreading work is not only caused by stagnation but also by an unhealthy work environment. If you wake up in the morning and would rather take a 2 hour shower and cry. Chances are you are in an extremely unhealthy work environment. This can be caused by a bad manager or a shitty employee maybe you been changing out printer ink for 5 years and want to move up in the world and aren’t getting that opportunity, either way this is a sign you need to leave that job and fast.

Einstein made a pretty simple equation back when he was making up science things, take heed.

UHWE x LIIJ=DICAM

In case you didn’t learn that in high school physics full read out is below.

(Unhealthy work environment x Lack of interest in job = disaster in career and mind)


Need more energy?

More coffee! Do you find yourself needing 4 or more coffee’s a day? Are you single and don’t have kids? Didn’t go out partying last night with the guy/girls? Just a normal working day? Chances are you are stagnant… or at least getting there. That doesn’t make sense Frank you must be crazy?!? Well when was the last time you needed to drink a coffee before you go to an amusement park or had a party? Not very often. It tends to be the more excited you are about a particular task the less artificial energy you need.

If you don’t get genuinely excited about changing printer ink or building a new ESXi host then you will need a little push to get up and do it. That is a sign of stagnation. Not really getting excited about the challenges that you are presented with. Regardless of how minute or honestly how uninteresting they may be shows that you are looking for a bigger more interesting challenge, and only you can find that new challenge and exploit it.


Practice makes a perfect stagnate environment

Repetition is the path to stagnation. Would you take a job for $120,000 a year sharpening pencils all day? Probably at first you would, hell I would too how hard can it be right? Well physically not very hard, But mentally I am sure it is torture. Waking up at the same time every day, making the same commute every day, doing the same task every day can get tiring really fast. Repetition is nice for learning code and such but what happens if you are not a coder? or what happens when you need to expand your mind beyond that handful of task’s? Don’t stand for a company that wants you to do one task all day. Your career is worth more than creating distribution lists all day.
