Hi, I'm trying to install pyrfc in windows - 10 VM x64 64-bit.

The pre-requisites I already installed i.e., visual studio and SAPNWRFC SDK. But while building pyrfc wheel I'm getting below error. Can you please help me on this to fix.

Which Python version and which pyrfc version are you using?

I could not reproduce with the current pyrfc and Python 3.7.6:

Could you please try if this works on your system and post the full log if there are errors:

git clone https://github.com/sap/pyrfc.git
cd pyrfc
python setup.py bdist_wheel

C:\PyRfc>git clone https://github.com/sap/pyrfc.git
Cloning into 'pyrfc'...
fatal: unable to access 'https://github.com/sap/pyrfc.git/': OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to github.com:443

Getting above error while cloning. So I downloaded the zip file from github directly and unzip in C drive

No idea what might be wrong. I could not reproduce with Python 3.7.4 either.

Perhaps to try on another machine and check if correct SAP NWRFC SDK is installed, like 64 bit Windows version, not 32 bit ?

okay, Is there any problem with Visual Studio..?? As in error it is showing like below

Yes, it might be an issue with the build toolchain.

Please check if all requirements are met: https://github.com/SAP/PyRFC#windows

Okay and also do you have any installation steps of SAPNWRFC SDK and pyrfc for Ubuntu 18.04.3..??

Here it is: http://sap.github.io/PyRFC/install.html#linux

You also check installation steps in these docker containers: SAP/fundamental-tools/docker

Thank you so much...!

And I'm able to install in my windows VM and I wrote some code for connection check. But I'm getting below error. Can you please suggest what is the error exactly is

Can you please check above error

bsrdjan commented Oct 1, 2021

It looks like a network error. Please check your system connection parameters.

You can also run the niping utility on your Python host, to check the connectivity with ABAP system: #241 (comment)

jfilak commented Oct 1, 2021

If you cannot install niping for any reason, you can also try TCP/IP connectivity by the utility telnet which is most probably avialbe on all operating systems.

If I try telnet on a live system with instance (sysnr) 02 with random input, I run the following on command line

telnet XXX.YYY.ZZZ.WWW 3302

and I get:

Trying XXX.YYY.ZZZ.WWW...
Connected to XXX.YYY.ZZZ.WWW.
Escape character is '^]'.

so I type:

HELLO

and the response is

Connection closed by foreign host.

But if I cannot connect to the system becuase of any TCP/IP problems (e.g. I unplug my ethernet cable), telnet hangs with:

Trying XXX.YYY.ZZZ.WWW...

yes, I'm able to hit the host using telnet. But via python I'm not able to connect over windows VM.

But I'm able to connect via python using my local windows machine

via python I'm not able to connect over windows VM.

My test VMWare VMs work in network shared mode. Perhaps you can try shared and bridged:

Hi, I checked with windows server support team and they said the firewall is blocking the destination port. So, I'm unable to connect via windows VM.

Thank you for the support..
