handshake failed: [ssh: no auth passed yet]

I tried the following on the ssh client:
```
$ ssh localhost hemlo
Unable to negotiate with 127.0.0.1 port 22: no matching host key type found. Their offer: ssh-rsa
```

and on the sshfront:
```
sudo ./sshfront -a "" -d -h 127.0.0.1 `which echo`
2025/02/25 04:16:58 host key file error: open ~/.ssh/id_rsa: no such file or directory

```

whether the ssh username is set or not, it still shows the same error
