Hi Madhu,

Have you checked the sapms<SID> <port> maintianed in your /etc/services file on both the hosts.

Also do perform the niping test on the host.

Let us know the output.

Hello Madhu,

Sorry, I am asking a dumb question, where are you running this tests such as ping, netstat, nslookup etc ? on your desktop or on the server hosting the JAVA instance where you are trying to setup the RFC?

Hi Madhu,

First check if the gateway is running in the target system using the below commands

ps -ef|grep gwrd   or     netstat -anp | grep <gateway port>

If running then you to check the connectivity form source to target using 'telent <ip> <port>'

THis will give results only if the telnet is enabled in the system.

Most probably the port might be disabled for external connections which can be resolved by contacting network admins.

Also check if the secinfo and reginfo files .

Hi Madhu,

ERRNO   10061 ERRNO TEXT WSAECONNREFUSED: Connection Refused Counter 2

Could you share results for command

niping -c -H <Host Name> -S 3351  or also with niping -c -H < IP > -S 3351.Please refer SAP Note  1341701 - partner 'hostname:service' not reached

Addition to it maintain host file entries as like

127.0.0.1  localhost.localdomain localhost
<IP>       <Host Name>

and make sure you maintained entry for port 3351 under /etc/services file of your system.One more thing which i would like to check on system is to completely disability of firewall & SELINUX modes (If on linux) or turn off of any Anti Virus as well as firewall in case of windows.

Hope this will also help you.

Hi Madhu,

From the NWA system, telnet the port

telnet 10.132.248.81 3351(if your connection is getting refused then you need to open the port 3351)

Moreover ping d51.sonyericsson.net if you are not getting the correct IP or host not found error then you need to maintain the below entry in hosts file

<IP> d51.sonyericsson.net d51

Hi Ashutosh,

I carried out telnet for the port 3351.

it is showing "could not open connection to the host, on port 3351: Connect failed"

You have mentioned that I need to open the port 3351. Can you pls let me know how to do it.

And also i tried to ping d51.sonyericsson.net , the ip is showing correctly but it is showing request timed out. Pls suggest me how to proceed.

Hi,

Please check at os level if the port 3351 is listening or not

You can use below commad

netstat -An|grep -i 3351 .If port is listening it will return a value

If not you need to contact your OS admin to open the port

can you check /etc/hosts file and see if entry d51.sonyericsson.net is maintained .

If not edit it and place below details

<IP of the d51.sonyericsson.net server>       FQDN(d51.sonyericsson.net)

Hi Madhu,

You need to contact your OS administrator to open the port 3351 from NWA system to <destination host>

Its a firewall setup between your NWA system and destination system.

Also share the details of your scenario.

And one more thing, while creating RFC destination I have not entered any value for gateway host and service

[former_member185954]

Hello,

is the IP address 10.132.248.81, ip address of the host - d51.sonyericsson.net  ? if yes, there is probably a firewall/antivirus running on or between the source and destination systems that maybe blocking communication.
