Supported Secure Gateay (SSH) ciphers

HI,


I am trying to connect to a RDP session through a (third party/sshd) Secure Gateway, but during connection it just says "There is no cipher supported by both: client and server (7)". Can anyone please tell me which ciphers RoyalTS expects to be available on the gateway side? Are those ciphers somehow configurable?


I am using RoyalTS 3.3.61216 (build #61216) on Windows 7 x64.


Thanks in advance.

Hi,


sorry, the post ended up in the wrong forum and got overlooked.


Are you still experiencing issues with your SSH server as secure gateway?

Hi Stefan,


the problem got resolved beginning with one of the more recent version of RoyalTS (4.x; not sure which version did it). I can now successfully use sshd-based tunneling.

Great to hear that and sorry for the long delay...


Please let us know if you have any further questions or issues.

Hi Stefan,


I have similar problem.

I am trying to use Secure Gateway to connect to linux machine using linux jump host.

Jump host has ssh config which only supports following key exchange algorithms: 


curve25519-sha256@libssh.org,ecdh-sha2-nistp521,ecdh-sha2-nistp384,ecdh-sha2-nistp256


When trying to establish connection error is:

"no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1 [preauth]"


According to Rebex documentation at least 2 of jump host's algorithms should be supported.

Is there a solution which I don't see?

Hi Mislav,


according to rebex, this is currently a bug in their components. They are already working on it and will fix it in one of the next releases.
