Issues using SSH from Cisco 2960S (client) to Juniper SRX (server)

[busterswt]

Hello all,

We're attempting to SSH from a Cisco 2960S to an SRX240, and are having some issues. The error we're seeing on the switch is:

ops-switch1#ssh -l root 10.10.10.1

[Connection to 10.10.10.1 aborted: error status 0]
ops-switch1#
*Mar 19 04:24:29.871 UTC: SSH2 CLIENT 0: Server has chosen 2056 -bit dh keys
*Mar 19 04:24:29.871 UTC: %SSH-3-INV_MOD: Invalid modulus length

Does anyone know what this means, exactly? And is there any way to work around this on either the server or client side? I cannot find any mention of this error anywhere so far...

Thanks in advance,

James

I am not authoritative on this issue. But I would suggest that you generate new RSA keys and specify a large modulus for the key.
