Cannot install SDC on ESXi 6u2

Jump to solution

Currently trying out a fresh install of ScaleIO in a lab environment, vCenter 6 with all updates applied, hosts are running the latest vendor-approved (Dell) ESXi 6u2. I was able to install the vCenter plugin without any issues, but upon trying to install the SDC on my hosts, I receive an error: "SSH - Connection Failed" for every host selected. Upon logging into the host (over SSH), I see errors noted in /var/log/auth.log.

2016-11-18T17:16:37Z sshd[264338]: Connection from 192.168.20.30 port 36472

2016-11-18T17:16:37Z sshd[264338]: fatal: Unable to negotiate with 192.168.20.30: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group-exchange-sha1

Has anyone else experienced this issue? If so, what was your workaround? I'm assuming I'll either have to change the SSHD config for each ESXi host to allow this insecure cipher, or find a way to reconfigure the ScaleIO plugin to use more secure ciphers. Is this supposed to be the default config? Unless I'm missing something drastic (Fairly certain I followed the deployment guide correctl), this prevent anyone from configuring a new VMWare Server+Client converged platform.
