How do I remove diffie-hellman-group1-sha1 from SSH on mgmt port? I've removed the CBC ciphers, but my vulnerability scanner is still showing that diffie-hellman-group1-sha1 is still available for SSH.
I'd also like to know how I enforce SSH server ciphers or other parameters on management ports via Panorama. I have about 60+ firewalls of various Palo models, with 8.1.13 installed. We use Panorama on appliances.
Having to send CLI commands to these devices is going to be an issue. I imagine editing the templates we use for the firewalls to add CLI changes may be possible, but what's the best practice way to push SSH management server changes to a pile of firewalls?
Note: I've seen that with 9.1 (and maybe 9.0) we can modify the kex algorithms available. It doesn't seem to be on 8.1.13. I just upgraded everything to 8.1.13, so I'm disinclined to update them all AGAIN! 😄
I do need to know the best way to get a CLI change to all sites. I'd expect I'd need to modify a template, one of the ones I currently use, but then can I add CLI changes to templates we've created in Panorama, and can the changes be seen on the Pano GUI when someone looks?
I have, thanks. It does work, except i need 9.0 or 9.1 to enable the KEX algorithms to be selected manually, to remove sha1.
My question is now, that I have a number of changes to the management port to do, how do I push them to 60+ firewalls in Panorama? I'd want to add these to an existing template. But maybe a new template that's "related" to some existing template?
