SSH -j (PoxyJump) configuration

Hi,

From what I have been reading in the forums, currently RDM does not support the SSH -J (ProxyJump configuration directive) option. This is causing me a major issue with continuing with RDM. I’m hoping support is either in the pipeline, I’m missing something, or there is a work around.

From the SSH man page:
-J destination
Connect to the target host by first making an ssh connection to the jump host described by destination and then establishing a TCP forwarding to the ultimate destination from there. Multiple jump hops may be specified separated by comma characters. This is a shortcut to specify a ProxyJump configuration directive. Note that configuration directives supplied on the command-line generally apply to the destination host and not any specified jump hosts. Use ~/.ssh/config to specify configuration for jump hosts.

In our case all external connections go through a bastion host (aka jump box, proxy host, ssh gateway). This means to connect to the host we want we use the equivalent to “ssh -J user@jumpbox.example.com user@targethost.example.com”. Without supporting the -J option we need to ssh into jumpbox.example.com and from there ssh into targethost.example.com. This is less than ideal and when managing many hosts it is a pain.

I have tried configuring the “Gateways” and “VPN/Tunnel/Gateway” sections In the SSH session, but either I’m doing something wrong or it is not working or not intended to work the way I thought.

Is there any solution to the above in RDM on iOS?

Relevant posts asking for the same feature:

https://forum.devolutions.net/topics/39118/is-ssh-gateway-jump-host-available-in-connection--vpnsshgateway#173705

• this one seems to ask for the same feature… the ability to configure a ssh gateway that could then be used in multiple ssh sessions would be ideal

Also, can you point out documentation of KB articles that show examples on how to configure and use the “Gateways” and “VPN/Tunnel/Gateway” options in the SSH session section.

Cheers,
