Before the cause of the SSH issues are explained, it is necessary to know about the 'SSH Server CBC Mode Ciphers Enabled & SSH Weak MAC Algorithms Enabled' vulnerability which affects the Nexus 9000 platform. CVE ID - CVE- 2008-5161 (SSH Server CBC Mode Ciphers Enabled & ...
ssh server cbc mode ciphers & ssh weak mac algorithms enabled recommendations: 1.1.) disable cbc mode cipher encryption, and enable ctr or gcm cipher mode encryption 1.2.)disable md5 and 96-bit mac algorithms. i looked into some documentations/forums and found the commands ...

SSH Weak MAC Algorithms Enabled The remote SSH server is configured to allow either MD5 or 96-bit MAC algorithms, both of which are considered weak.Note that this plugin only checks for the options of the SSH server, and it does not check for vulnerable software versions. Contact the ...
A fix for a weak SSH key generation issue is available in GitKraken v8.0.1. See the steps you can take to maintain secure SSH key connections to your remote repositories.
How To Disable Weak Cipher And Insecure HMAC Algorithms in SSH services for CentOS/RHEL 6 and 7 Edit/etc/sysconfig/sshdand uncomment CRYPTO_POLICY line: CRYPTO_POLICY= Edit/etc/ssh/sshd_configfile. Add Ciphers, MACs and KexAlgorithms have been added ...
PubkeyAcceptedAlgorithms +ssh-rsa Hit Control+O to save, and Control+X to exit. Try using SSH to connect to a server with RSA keys again, it should work as intended. While you’re at the command line, you can alwaysenable ssh from Terminalas well if you’d like, allowing for inbound...
Note that this feature is definitely for those who know what they're doing here.(I think the random order of more secure algorithms is still better than offering weak algos, so I'd not revert the code change done above by@AdSchellevis.) ...
Lately, GitHub eliminated standards of cryptography that were considered weak. To fix the issue, I removed PuTTY 0.63 from my system and updated it to the most recent release, which is currently 0.70. This solution worked perfectly for me. ...
but since some of the older algorithms have been been found weak not all are algorithms are enabled by default. This page describes what to do when OpenSSH refuses to connect with an implementation that only supports legacy algorithms.
