connections refused - saprouter

dear all,

I want to test a saprouter and i can´t connect because it gives the error 10061.

I can´t telnet to the public IP with problem the port is opened but no sap.

My saprouttab file is complete open for test only

P * * *

Saprouter installed as service and running.

My saprouter is running on the host (10.10.1.5) and the SAP-ECC is running on virtual machine inside the host (with 10.10.1.6).

All the firewalls are down.


What could be the problem.

regards,

    Hi Nelson,

    Could you share dev_rout log file ? Meanwhile try to check with successful connectives of SAPOSS RFC connection & can refer SAP KBA at  1835162 - SAP Basis System: Operating system call connect failed (error no. 10061) 10061: WSAECONNREFUSED: Connection refused

    Regards,

    • Hi SS,

      this saprouter is the last one downloaded from the SMP. The note says to upgrade the kernel, so it means the kernel for the SAP System.

      Note that the saprouter is installed on a separated machine than the 3 system (SDV, QAS and PRD)

      Regards,

    Hello Nelson:

    What is the result of this telnet command when you execute from saprouter host?

    telnet <Your SAP ECC server IP> 32<Instance Number ECC>

    Please share the contents of your dev_rout file from saprouter host?

    Thanks

    • Hi Nelson:

      For the Router to communicate with your SAP systems through internal Firewall you need to have specific ports open depending on what type of service connections you want to allow. In addition port 3299 needs to be opened on internal and external firewall for saprouter.

      If port 3299 is open for saprouter IP your RFC SAPOSS should work.

      What is your setup?

      Thanks.

    Hi Nelson,

    C:\Users\nchamba>telnet XXX.XXX.XXX.XXX 3200

    Connecting To XXX.XXX.XXX.XXX...Could not open connection to the host, on port 3200: Connect failed

    Above result shows issue is related with port block at your end by firewall or system firewall.Suggest you to disable system firewall once to check it again by sharing result for command

    telnet <IP of server> 3299

    In resume you could refer SAP Note  1165633 - Connection problems after network cable was pulled out

    Hope this will help you.

    Regards,

    • Hello Nelson,

      The first screenshot shows that the saprouter running at the server "jupter" was unable to connect to the SAP system 00 at the IP address 10.10.1.5.

      However, that would be the IP address from the saprouter itself, based on the information you sent.

      Is the SAP ECC running at the same server as the saprouter?

      If no, I believe that your saprouter string (at the SAP GUI) is incorrect.

      In that case, the router string should look like:

      /H/<saprouter server>/S/<saprouter port>/H/<SAP ECC server>/S/<SAP ECC port>

      In your case:

      /H/10.10..1.5/S/3299/S/<SAP ECC server>/S/3200

      Regards,

      Isaías

    Hi Nelson,

    the telnet <firewall-IP> 3299 is OK, no error.

    Could you share result for same ? Instead of firewall you should give IP of saprouter,so the command would be as like

    telnet 10.10.1.5  3299

    IP 10.10.1.5 is your static one ? If possible could you share telnet result with local bind IP which you've binded with 10.10.1.5 under your firewall NAT configurations.

    Regards,

    Hi Nelson,

    All you need do here is to maintain the address 194.x.x.x  and sapserv(2) or (3) depending on the server your Public IP was registered with at SAP in your host file (just the way you maintain IPs and host names) and your connection would be established.

    Provided you have done all you mentioned earlier.
