Hello Experts, I am quite new to the linux environment which makes make me new to SUSE as well. This is my first post here. I have installed SLES 11 on VMware. The reason for this is to install SAP HANA on this server. I have performed all the preinstallation steps. When started the installation process, I get the following error: [COLOR="#FF0000"]‘There is no hostname bound to computersystem Either check your computersystem or your model’[/COLOR] Can you please let me know what could be reason for the error? I have checked the /etc/hosts file and I can see my IP, fqdn and the host alias that I have added using the Hostnames through YSaT. Appreciate your help. Thanks, Balajii ---

If this error is coming from the SAP installation then there is probably a problem with that install; you may want to ask them, as a result. It’s not really possible to have a Linux system without a hostname, but perhaps the check by the SAP installer for a hostname is looking in the wrong spot, or is making a bad API call to find the nostname, or just just insane in some other way. The way for a user to find out their system’s hostname, besides looking at the default shell’s prompt or login screen, is to run the ‘hostname’ command. Good luck. ---

Dear Ab, Thanks for the reply. When I run the ‘hostname’ command from the terminal, I get the hostname that was mentioned in the hosts file. But when the SAP installter runs, it says that the hostname is not bound to any computer system. Can I ask you on how to assign/change a hostname to a linux computer? Thanks, Balajii ---

Load Yast: Network Devices: Network settings, or just run the following as ‘root’: ## Code: ## /sbin/yast lan Still, something else in the installer is either wrong or giving you a really lousy error message. Perhaps look at the ‘Assign Hostname to Loopback IP’ checkbox under Hostname/DNS settings. If checked, uncheck it. If unchecked, that’s probably good, but doesn’t help with your SAP issue. Good luck. ---

Dear Ab, This is exactly what I wanted to do. I know how to do this on windows server. But in linux I’m not sure on how to assign the IP to the loopback adapter. I have checked under the Hostname/DNS settings but no check box or anything with this option. THanks, Balajii ---

[color=blue] > check box or anything with this option.[/color] What do you see on that page? The checkbox was there for me, so it seems odd that it would not be there for you. Good luck.
