OpenSSH‘s sshd is run by default at start-up. It’s listening on IPv4 and IPv6. The username it expects is fuchsia.
An SSH key is generated at build time and included in authorized-keys. An ssh_config referencing that key is also generated. The easiest way to ssh to your default Fuchsia device is:
ssh -F $FUCHSIA_BUILD_DIR/ssh-keys/ssh_config \ $($FUCHSIA_OUT_DIR/build-magenta/tools/netaddr --fuchsia)
Similarly you can scp or sftp using the same config file. Note that scp and sftp require the ipv6 address to be in square brackets, unlike ssh.
sftp -F $FUCHSIA_BUILD_DIR/ssh-keys/ssh_config \ [$($FUCHSIA_OUT_DIR/build-magenta/tools/netaddr --fuchsia)] scp -F $FUCHSIA_BUILD_DIR/ssh-keys/ssh_config \ /local/path/file.txt \ [$($FUCHSIA_OUT_DIR/build-magenta/tools/netaddr --fuchsia)]:/remote/path
NOTE 1: Transfers of large files will stall and eventually fail. The cause is being investigated.
NOTE 2: There remain some serious issues with the shell terminal handling. Escape characters in the prompt are printed verbatim. Enter must be pressed twice to run a command.
The clients are built but don't work yet.
