Installed Ubuntu 20.04.2 LTS as Virtual Guest in VirtualBox 6.1.16
Guest has no ssh connection from Windows 10 Home 20H2.
You are trying to define a Unit configuration file for ssh in systemd.
I think the file is misplaced, but I'm worried about what's wrong.
I tried 、 and を below, but it doesn't work.
①Initially, we placed sshd.service as the Unit configuration file below.
/etc/systemd/system
However
$ systemctl start sshd.service
and
Failed to start sshd.service:Unitsshd.service is masked.
will be
$systemctl unmask sshd.service
is removed when you run , and the Unit file is /etc/systemd/system
Removed from the .
次 Next, /usr/lib/systemd/system
Place the sshd.service file in the directory and
/etc/systemd/system
I copied it below.
Still, like と, if you execute the sshd start command, it becomes masked.
Unmask will delete the configuration file.
You have already configured the host-only bridge adapter in VirtualBox.
We also added a configuration to allow SSH to ssh_config.
Add the following configuration to the end of /etc/ssh/ssh_config
Port 22
PermitRootLogin no
PasswordAuthentication yes
That's all.We would appreciate it if you could provide us with information.
linux ubuntu ssh virtualbox
Simply do the following to connect.
apt-y install openssh-server
systemctl restart ssh
/You should modify /etc/ssh/sshd_config to prevent root login.
Connect ssh to the network address IP of the host only adapter.
N The network address IP of the NAT network could not connect to ssh.
ブリッジI have never used a bridge to join the host OS network.
[Additional note]
My environment is manually configuring IP for VMs.ホスト Specify the IP that belongs to the network address of the host only adapter
Since the host OS IP is a different network address, we are routing it as follows:
route add-p network address of host only adapter / 24 host only adapter IP
After removing the routing as a trial, the ssh connection from the host is no longer possible, so I would like to supplement it.
