Include one of the supported MAC algorithms in the sshd_config file. For example, for FglAM v188.8.131.52.1, include one of the following MAC algorithms in the 'sshd_config' file:
EXAMPLE: MACs hmac-sha1-96,hmac-sha1,...
NOTE: If the “diffie-hellman-group-exchange-sha1” key exchange algorithm is disabled on the monitored host, the DellUnixAgent and UnixAgent will not be able to connect even if one of the supported MAC algorithms is used in the sshd_config file. The "diffie-hellman-group-exchange-sha256" key exchange algorithm is also supported in version 5.9.1 of the FglAM and higher.
Enhancement FAM-7114 is implemented for Linux monitored hosts in FglAM v184.108.40.206.2. FglAM v220.127.116.11.2 supports more MAC algorithms for Linux hosts, including hmac-sha2-512, hmac-sha2-256, and hmac-ripemd160.
Enhancement FAM-7145 is implemented in FglAM v5.9.1.
