SSH test fails against Synology update

[mrmichaelbeck]

Hi there,

We've got HostMonitor v. 9.90 (RCC 4.90) running several SSH tests to make sure that our Synology disk stations are up and running. The test script is simple. It just returns the up time.

We recently updated the Synology boxes to 5.1-5022 Update 1 (https://www.synology.com/en-us/releaseNote/DS412+) which includes an update to OpenSSL 1.0.1k. Since the upgrade, the tests have been getting the following error...

"Protocol error. Encryption ciphers are not supported by client"

Using Putty from the machine the test runs from yields the correct results. Writing a powershell script and using an ssh module works properly too. It only seems like HostMonitor is having the troubles.

Is the client in HM compatible with that version of OpenSSL?

Probably you need unofficial HostMonitor update that can work with new OpenSSL when some ciphers disabled.

or probably you can switch to SNMP test and get uptime using SNMP protocol?
Its faster and uses less resources than SSH.
If not, please send e-mail to support@ks-soft.net
