SAP Login Problem in Newly installed SAP

Hi expert,

host machine---Win7 64 bit

Virtual Machine---RHEL 5.3

i installed ECC 6.0 with oracle 10.2.04.0 on RHEL 5.3 successfully on Virtual Machine.

but i can't login via host machine(win 7).

i checked all the things on RHEL all are ok.

like database is up,

pf -ef show the work process and R3trans -d finished by 0000 RC.

So why i can't login to SAP.

Any thing is missing Please suggest me.

Regards,

Vovek
