Can't startsap n4shost - Could not found virtuell host in ifconfig list

[Former Member]

Hi,

I try to install SAP NetWeaver 7.0 (2004s) - Trial Version on Linux however without success.

OS: opens suse 10.3

I face the following issues:

1. when I install the system I can startsap n4shost without issues however after reboot I get the below listed message (I copied as well all relevant files into this tread)

2. the license key I received is too long (the system asks for 24 characters I received from sap in a text file a >100 characters license key

What do I wrong? I found some similar issues in the forum however non of the solutions fixed my issues....

Thank you for your help.

Regards

Sebastian

Hi RK, hi Marcos,

thank you for your reply.

Sorry, when I copied the host file the last line got lost. There is an entry in the file /etc/host for n4shost.

127.0.0.1 localhost

::1 localhost ipv6-localhost ipv6-loopback

fe00::0 ipv6-localnet

ff00::0 ipv6-mcastprefix

That's what I get --> HP6735B:/etc # ifconfig -a

As well I have a fix IP address...

Do you have any ohter idea what could be wrong?

Looks like the network interface for n4shost is not there. ifconfig -a output does not show IP 192.168.155.1. That explains the warning

n4shost:n4sadm 3> startsap n4shost
Warning: Could not found virtuell host in ifconfig list

Can you configure the interface and try it again? Can you post the startdb.log & trans.log as well?

Hi Sebastian,

I guess 192.168.155.1 is not a valid IP-address... in this case for a first test is enough to change your /etc/hosts like below:

127.0.0.1 localhost

::1 localhost ipv6-localhost ipv6-loopback

fe00::0 ipv6-localnet

ff00::0 ipv6-mcastprefix

ff02::1 ipv6-allnodes

ff02::2 ipv6-allrouters

ff02::3 ipv6-allhosts

127.0.0.2 linux.site linux

192.168.1.2 HP6735B HP6735B n4shost

Do you have DHCP configured in this server?

cheers,

Marcos

Hi,

192.168.155.1 is of course a valid IP address. Just execute

ifconfig eth0:0 192.168.155.1 netmask 255.255.255.0 up

and you have a valid interface

Thanks,

Hannes

Hi Hannes,

Sure 192.168.155.1 is a valid IP address, but since the netmask is 255.255.255.0 no other PC in the segment 192.168.1.x will be able to reach the SAP server! So I think is not that useful to define the interface as you proposed. But, of course, depends of the Network layout and many other things.

Hi,

I have changed the file /etc/hosts -now it works:

127.0.0.1 localhost

::1 localhost ipv6-localhost ipv6-loopback

fe00::0 ipv6-localnet

ff00::0 ipv6-mcastprefix

ff02::1 ipv6-allnodes

ff02::2 ipv6-allrouters

ff02::3 ipv6-allhosts

127.0.0.2 linux.site linux

192.168.1.2 HP6735B HP6735B n4shost

Thank you for your help.

Hi Sebastian,

When you installed the did the /etc/host file contain an entry for n4shost? It does not exist in the host file you listed above. Also, there doesn't seem to a network interface configured for n4shost. I am not all that familiar with linux, but you can check with ifconfig -a <ipadress of n4shost>.

-Regards

I had similar problems because DHCP was configured and the /etc/hosts was always wrong! Since I changed to a fix IP address everything works fine.

The new long license you should apply in the SAP with transaction SLICENSE. The old "saplicense -install" works only with a short key, which is not delivered any more.

cheers,

Marcos
