Dear All,


I hit the following error when used 'openssl s_server -no_tls1' command to
disable TLS1.0 on Redhat Linux server. It shows the openssl version as well.



$ openssl version

OpenSSL 1.0.1e-fips 11 Feb 2013

$ openssl s_server -no_tls1

Error opening server certificate private key file server.pem

140057863432008:error:02001002:system library:fopen:No such file or

140057863432008:error:20074002:BIO routines:FILE_CTRL:system

unable to load server certificate private key file



I can't confirm if the command format is fine or not. Would you please help
to correct me?


Thanks and Regards,

Chobin Guo
