SSH KEX Algorithms

[ScottBUK]

Hi,

I have a number of APC/SE devices - Smart UPS 1500, AP8953, AP8959NA3, APDU9959NA3 and AP7920B and want to know if there's any way to disable certain SSH key exchange algorithms.

Currently the devices report that they support diffie-hellman-group-exchange-sha1 and diffie-helman-group1-sha1. I'd like to disable these if possible.

All devices are on what I believe are the latest versions:

AP8953 with NMC AP9538 - rpdu2g 6.8.0, aos 6.8.2

AP8959NA3 with NMC AP9538 - rpdu2g 6.8.0, aos 6.8.2

APDU9959NA3 with NMC 0N-1556 - rpdu2g 1.0.0.28, aos 1.3.2.3 (not sure this is the latest - the SE website tells me to use the HW05 firmware, but mine seems to be HW21 and so says it's not compatible)

AP7920B with NMC 0G-1238 - rpdu2g 6.5.6, aos 6.5.6

Hi Scott

There is no way to change/disable the key exchange algorithms on the units you mention.

Best regards
