Sap Netweaver 4.0 testdrive on linux - impossible to connect from sapgui

Hi guys,

i've just finished to install the NW40 testdrive on a linux box, based on Redhat 9.0 distro (as requested by the equirements). At the end of installation, i have two boxes

One box with winxp sp1 called Darkstar with i.p. 192.168.100.1 and Subnet mask 255.255.0.0

The second box (with linux and NW40) called Darkmoon (prob. i was too bored to think a completly different name 😊 ) with i.p. 192.168.100.15 and subnet mask 255.255.0.0

The /etc/hosts file of the linux box contain these entries :

127.0.0.1 Darkmoon

192.168.100.15 Darkmoon.locadomain.ext

195.155.155.1 nw4host

The last line was taked from other posts found in SDN forum. I followed all the install steps and the db and the instances going-up very well, without any problem.

If i ping the two boxes, they reply each-others (from winxp to linux and vice-versa).

The "hostname" command in the linux box, return only "Darkmoon" as request by installation steps.

Now the problem.

On the winxp box i have installed sapgui 6.20. In it, I've created an entry with these information:

Description : Linux box

Application server : 192.168.100.15

System number : 00

When i try to connect with double clink on that entry, i have the following error :

Partner not reached (host 192.168.100.15, service sapdp00)

Component NI (Network interface)

Release 6.20

Ver 36

Return code -10

System call SO_ERROR

Error text : WSACONNREFUSED

Seems the boxes don't see between them.

Could be a hosts file problem on linux box???

Someone of u could give me some help ??

Could be very unhappy couln't use NW40 just for a little error.

Thx a lot for all your hints and suggestions
