adze
is an SSH+SFTP userspace server which authenticates only the running
user by public keys. It enables tooling like rclone work for the systems
that have 2-factor authentication.
Distributed as single static binary, it works anywhere.
Loging to the remote, enter your codes, and start adze:
ssh -L 33456:localhost:33456 cluster
$ adze -p 33456
The you can point your tools to localhost:33456
:
ssh -p 33456 localhost
