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!

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!
