How to disable SSH Server CBC Mode Ciphers in CSPC 2.8

[kumar.abhijit1]

Hi All,

Can you please help me to disable CBC mode cipher encryption, and enable CTR or GCM cipher mode encryption for SSH connectivity in CSPC 2.8.

The most recent release for CSPC, 2.8.1.6, has the following ciphers enabled in /etc/ssh/sshd_config;

Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc

You may wish to remove the CBC ciphers and run service sshd restart.
