openssl command hangs while generating .p12 file - Git Bash environment

openssl commands hangs while generating .p12 file - Git Bash environment 

 openssl command will remain hang if you are trying to generate the .p12 file from the SSL cert , the only option to come out of hung state is to use the Ctrl+C and it will not generate the .p12 file. 

The issue can be resolved to use the winpty before the openssl command and it will generate the .p12 file. 

$ openssl pkcs12 -export -in ssl_cert_file.crt -inkey ssl_crt_key_file.key -out ssl_cert_file.p12 -name "test command to generate the p12 file" 

Ctrl+C 

use the winpty command and it will work 

$ winpty openssl pkcs12 -export -in ssl_cert_file.crt -inkey ssl_crt_key_file.key -out ssl_cert_file.p12 -name "test command to generate the p12 file"

Oracle 12c install error - Oracle Net Configuration Assistant keep searching the listener ports - Checking for free port in range: 1521-1540 - Validating end-point: TCP:1521

Oracle 12c install error - Oracle Net Configuration Assistant keep searching the listener ports 

The installer will stuck on the Oracle Net Configuration Assistant and will never complete, it will keep searching the listener ports, starting from 1521, it will keep searching the next port 1522, then so on. 

Even the listener port 1521 is free and not being used, but Net Configuration Assistant keep putting the following messages in the directory "cfgtoollogs/netca"

Resolution:

- check the /etc/hosts file, it should contain the fully qualified name of the host machine with the IP.

- update the /etc/hosts with the correct hostname / ip and Oracle Net Configuration Assistant will pick the right hostname and will get the listener port for the configuration.

- to make sure check the installer screen , also log file can be checked under "cfgtoollogs/netca"
