vagrant up ssh is slow

[Carlo Corradini]

Launching comnetsemu using vagrant up takes a lot of time due to comnetsemu: SSH auth method: private key

Hi, thanks for the report. Can you provide the versions of vagrant and virtualbox you used? Or maybe you're using the libvirt provider ? This issue may be related to some network configuration of your VM provider. I can not reproduce this issue on my side easily...

[Carlo Corradini]

vagrant: 2.2.19
virtualbox: 6.1.32
I simply type vagrant up and on ssh operation(s) it's super slow to connect to the machine.

I use the same versions without issue... I'm not sure about the issue and maybe it's related to the host-only network adapter of the virtualbox ? Or maybe your firewall configuration ?

You can also ssh into the VM with ssh command directly:
Run vagrant ssh-config to get the SSH configuration as shown below:

Host dev
  HostName 192.168.121.48
  User vagrant
  Port 22
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  IdentityFile /home/some_path/private_key
  IdentitiesOnly yes
  LogLevel FATAL
  ForwardAgent yes
  ForwardX11 yes

Then you can SSH into the VM with ssh -i /home/some_path/private_key vagrant@192.168.121.48.
You can use ssh -v -i ... to have more debug information.
Maybe this helps you to figure out the problem.
