ScreenConnect / ConnectWise Control not working on RHEL/Oracle Linux- service runs but doesn't work or garbled screen.

I recently had a problem where I loaded ScreenConnect for remote access to a RHEL server. I imagine this is similar for other distros, Centos, Rocky. It has happened on Oracle Linux.




First thing you need is Java. The stupid thing is, it will install without it. But it won't work.
sudo yum install java-1.8.0-openjdk

Then you'll need to disable  Wayland-
sudo nano /etc/gdm/custom.conf

Uncomment this-

WaylandEnable=false

Check the service-

systemctl --type=service

Start or Restart the 'Connectwisexxx"

systemctl status ConnectWisexxx

systemctl start/stop/restart ConnectWisexxx

If you still have issues, check the logs-

/var/logs/messages

/var/logs/connectwise***

You may get this error. My provider does air gap behind the scenes. You can disable this with the below registry change-

Move SQL Temp DB to alternate partition

If you need to move your temporary databases to another partition-

USE master
GO
ALTER DATABASE tempdb
MODIFY FILE( NAME = temp2, FILENAME = 'F:\MSSQL\DATA\tempdb.mdf' )

ALTER DATABASE tempdb
MODIFY FILE( NAME = templog, FILENAME = 'F:\MSSQL\DATA\templog.ldf')

ALTER DATABASE model
MODIFY FILE( NAME = modeldev, FILENAME = 'F:\MSSQL\DATA\model.mdf' )

ALTER DATABASE model
MODIFY FILE( NAME = modellog, FILENAME = 'F:\MSSQL\DATA\modellog.ldf')

ALTER DATABASE msdb
MODIFY FILE( NAME = MSDBData, FILENAME = 'F:\MSSQL\DATA\MSDBData.mdf' )

ALTER DATABASE msdb
MODIFY FILE( NAME = MSDBLog, FILENAME = 'F:\MSSQL\DATA\MSDBLog.ldf')

Move files, restart service.

SQL Windows Firewall

I set up a lot of SQL servers. Here are the powershell commands to allow the sql ports. Please don't be 'that guy' who shuts off the firewall.

New-NetFirewallRule -DisplayName "SQLServer default instance" -Direction Inbound -LocalPort 1433 -Protocol TCP -Action Allow

New-NetFirewallRule -DisplayName "SQLServer Browser service" -Direction Inbound -LocalPort 1434 -Protocol UDP -Action Allow

You can also do it with netsh in DOS.

netsh advfirewall firewall add rule name = SQLPort dir = in protocol = tcp action = allow localport = 1433 remoteip = localsubnet profile = DOMAIN

netsh firewall set portopening protocol = TCP port = 1433 name = SQLPort mode = ENABLE scope = SUBNET profile = CURRENT
