Question & Answer
Secure shell allows you shell access to your servers, without the concern for transmitting plain-text passwords. Of course, shell access isn't limited to UNIX-like servers. Even Windows machines. SSH (or Secure Shell) is a great service to enable on your Mac at home or work. This useful tool not only enables the ability to remotely access the command line interface of your Mac, but also to. Secure Shell is an xterm-compatible terminal emulator and stand-alone ssh client for Chrome. It uses Native-Client to connect directly to ssh servers without the need for external proxies.

SSH or Secure Shell is a cryptographic network protocol for operating network services securely over an unsecured network. Typical applications include remote command-line, login, and remote command execution, but any network service can be secured with SSH. SSH provides a secure channel over an unsecured network by using a client–server architecture, connecting an SSH client application.
Question
Is it possible to disable SSH Server CBC Mode Ciphers SSH and SSH Weak MAC Algorithms in IBM Secure Shell Sever?
Cause
Security scans may report SSH Server CBC Mode Ciphers Enabled and SSH Weak MAC Algorithms Enabled vulnerabilities.
Answer
The default ProgramDataIBMibmsshetcsshsshd_config file may contain lines similar to the ones below:
# default is aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,
# aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,aes192-cbc,
# aes256-cbc,arcfour
# default is hmac-md5,hmac-sha1,hmac-ripemd160,hmac-sha1-96,hmac-md5-96
To disable CBC mode ciphers and weak MAC algorithms (MD5 and -96), add the following lines into the ProgramDataIBMibmsshetcsshsshd_config file.
Ciphers aes128-ctr,aes192-ctr,aes256-ctr
MACs hmac-sha2-256,hmac-sha2-512
Restart ssh after you have made the changes. To start or stop the IBM Secure Shell Server For Windows, use the Windows Services Microsoft Management Console. Alternatively, use the net start ibmsshd or net stop ibmsshd Windows commands. You can test the new configuration using

Install mac os x 10.11 el capitan.app. ssh -vvv <hostname>
Mail app doesnt work on mac. The example below shows the modified ciphers and MACs being supported by the remote server when running ssh -vvv <hostname>.
