In our most recent security scan, one of our HP ProCurve switches was shown to have SSH1 enabled. We have a A5830AF-48G.

 

From what I've read, SSH1 is enabled by default. I have not found a way to disable it while still keeping SSH enabled. I've checked the GUI and command references. There's a command to enable SSH1, which is already enabled by default.

 

Enable the SSH server to support SSH1 clients.

 

'ssh server compatible-ssh1x enable'
 

Optional. By default, the SSH server supports SSH1 clients.

 

So does anyone know how to disable SSH1?

don't have an hp but look through the different commands

 

start with

 

ssh server ?

yeah i did all that. there's nothing that shows 'disable' anything. even the manual doesnt show it, which is why i started the topic.

 

ambroos - you really think i didnt search online for this before posting? :huh:

 

also, that command doesnt work.

Ok the command is

no ssh server compatible-ssh1x enable

 

 

the description of compatible-ssh1x enable command is:

Use the ssh server compatible-ssh1x command to enable the SSH server to support SSH1 clients.

Use the undo ssh server compatible-ssh1x command to disable the SSH server from supporting SSH1 clients.

By default, the SSH server supports SSH1 clients.

This configuration takes effect only for users logging in after the configuration.

Related commands: display ssh server.

 

if you don't have ssh1x clients, then you would be fine...however if you do have ssh1 clients it will break and the ssh1 clients will not be able do connect.  this command enables backwards compatibility.

    • Smart Launcher seems a better option right now.
    • Mistral AI's new 'Magistral' models bring traceable, faster AI reasoning by Paul Hill One of Europe’s leading AI companies, Mistral, has announced the availability of its Magistral reasoning model. It comes in two versions: there is the open-source Magistral Small (24B parameters) and the enterprise-focused Magistral Medium. Magistral has been designed to better handle domain-specific tasks such as law, finance, and engineering. It shows users the model’s thought processes so that it’s more transparent, and it supports multilingual reasoning to perform better when tasked with answering non-English queries. Key features and performance Mistral compared its new models against DeepSeek R1 in various benchmarks. Ones that stood out were its results on AIME2024, which assesses reasoning capabilities. Magistral Medium scored 73.6% (90% with majority voting @64) while Small scored 70.7% (83.3% respectively). If you’ve used DeepSeek R1, you’ll have seen it thinking before answering. Magistral now does this too and can do it across multiple languages, including English, French, Spanish, German, Italian, Arabic, Russian, and Simplified Chinese. Interestingly, there’s also a Flash Answers mode that speeds up the thinking for 10x faster responses compared to competitors. Real-world applications and availability Thanks to the expertise Magistral has been trained on, organizations across multiple fields, including legal research, financial forecasting, and regulated industries, may be able to turn to Magistral for more reliable answers. Its traceable reasoning also makes it ideal in regulated fields for compliance and auditability. Magistral Small, the open-source model, is available under an Apache 2.0 license via Hugging Face. Magistral Medium is accessible through Mistral's Le Chat and via API on La Plateforme. It’ll also be arriving soon on Amazon SageMaker, IBM WatsonX, Azure AI, and Google Cloud Marketplace. The easiest way for readers to try it out is on Mistral's Le Chat platform; just head to chat.mistral.ai to get started. Source: Mistral
