The default installation of SAP Netweaver AS ABAP Developer Edition on openSUSE might not start all services after a reboot.
An indication of the problem: port 3300 is not open. After an attempt to connect from SAP Logon you’ll get following error:
WSAECONNREFUSED: Connection refused
When you logon to the system with SAP you may see that some of SAP processes are running, but not all of them:

As you can see there are two system accounts running on the system: sapadm, npladm. NPL is in my case System ID. The start command should be executed under npladm identity.
Launch following command as root of the system (change npladm to you own System ID):
su -c "startsap all" -l npladm
The system will start with following messages displayed in the console:

You can check whether port 3300 is open:
netstat -anp | grep 3300 tcp 0 0 0.0.0.0:3300 0.0.0.0:* LISTEN 20212/gwrd
You should be able logon to the SAP on openSUSE without a problem.
If you’re still not able to access the machine from remote then it’s necessary to check the firewall configuration. openSUSE has a strict firewall when using default installation.
You can change firewall configuration by the command:
yast2 firewall
