Connecting to "localhost" on port "21212" failed

Question

I run startinstgui.bat to install WEBAS640SP9 before I downloaded J2sdk-1_4_2_06.
I got error message with Connection to SAPinst can not be establish - Connecting to "localhost" on port "21212" failed. I tested with different values - no result.
Any idea?

Maybe this could be the case.....
You have a fault in your network and hostname configuration.
You hostname should be different to localhost.
- > rename your full qualified hostname
-> e.q linux.mydomain.foo
You can use the configuration tool Yast to change it.
It should be able use the command ping with your hostname
If the name of your host is linux.mydomain.foo
ping linux
ping linux.mydomain.foo
should work.
If your full qualified hostname is linux.mydomain.foo the file
/etc/hosts should be
127.0.0.1      localhost      localhost.localdomain
127.0.0.2      linux          linux.mydomain.foo
It is important that localhost and linux are mapped to a differnt IP
address. Something like
127.0.0.1   localhost    localhost.localdomain   linux
do not work.
The best choice to run the NW4 testdrive is to use Suse 9 because you do
not need to change any configuration. On Suse 9.1 the NW4 also runs but
you have to set an environment variable and you will get an error
message because of kernel 2.6
Also don't forget start boot.sysctl at boot time.
ln -s /etc/init.d/boot.sysctl /etc/init.d/rc1.d/S99boot.systctl
ln -s /etc/init.d/boot.sysctl /etc/init.d/rc3.d/S99boot.systctl
ln -s /etc/init.d/boot.sysctl /etc/init.d/rc5.d/S99boot.systctl
/sbin/sysctl -p
