Open port on Linux
We have SAP HANA DB running on Linux server. The server has 3 NICs configured for Administration, Data and User network access with IPs XX.XX.XX.1, XX.XX.XX.2 and XX.XX.XX.3. I need to open a port for database connections originating from a windows server (ODBC) on the Data network. All 4 servers are under the same network, there should not be any firewall issue, but checking through Telnet command i figured that the port is open for Admin and User network and connections work fine when i used there host details, but it is not open for Data network.
I can log into Admin network (XX.XX.XX.1) via PUTTY (root) but not into Data network (XX.XX.XX.2) directly.
Is there a way i can use the putty session in Admin network to open the required port in Data network? If not what would be the best way of doing it.
