The list of algorithms in 4.7.0 with old algorithms support disabled:

Hi guys! how i can access by SSH from a Mikrotik Terminal to a ePMP in v4.7.x with old algorithms support disabled?
All settings i try say: “can’t agree on KEX algorithms”
I try enabling and disabling ‘/ip ssh strong-crypto’, test with 1024, 2048, etc etc… nothing work!

Thanks and regards!

Which software do u have on your mikrotik ?
There is ssh v1 on the old mikrotik firmware, which should not be used for security reasons.
Try updating to version 7.x.x on mikrotik

Where is the ePMP device? Are you able to try with it being directly connected to the MikroTik to rule out any network issues? Also what RouterOS Version?

I have no issues from RouterOS 7.10 to ePMP 4.7.0.1

Hi, all my mikrotik network has last stable v7.x

Hi Daniel, the ePMP is directly connected and powered by the Mikrotik PowerBox.
I think i was clear in the post…
When the ePMP has the option “Deprecated SSH Algorithms” is “Enabled” or allowed, i can connect by SSH correctly…
The problem is when this option is not allowed “Disabled”

I like to add this security feature on my ePMP network, but i need to have SSH access from Mikrotik devices directly connected.
All the towers of my network is powered by Mikrotik PowerBox.

Just tried: mikrotik 7.9.2 → ePMP 4.7.0.1 with “Deprecated SSH Algorithms” disabled and it works, successfully logged in.
