Hello,
I’ve tried to update Linux OpenSSH on Rancher, but there’s no necessary tools in the system (like telnet, apt-get, etc.).
How can I resolve it?
RancherOS is a VERY minimal linux distribution, so you wouldn’t have those tools in it. You can use a docker container of Ubuntu or debian, or something and do with that what you want.
However, regarding updating OpenSSH, I’m not sure. Do you plan to compile it yourself, and just replace the binaries?
