heres a script to clean up all those vboxnets left by private_networks.

make sure you dont have any vagrant files running and remember to fill in "exceptions" if you have any host onlys your want to keep!

I have installed vagrant, but when I try to get to it via web browser I get site can't be reached.

Is there a formal term for the "works on my machine" problem that Vagrant is used to prevent and resolve?

Hi everybody!! I have a real problem with Gitlab installation with Vagrant VM.
I have done the installation of Gitlab correctly , but when I restart Vagrant
I can't use "gitlab-ctl" command . I verify on "/etc" I don't see "gitlab-ctl" repertory.
What's the problem ?

If you vagrant up a lot with debian based systems, it sucks to keep reaching out to the internet. One solution is to keep a permanent VM running with an apt-cache (i use squid-deb-proxy)

This way, if someone using your vagrantfile doesnt have one, it just skips it.!topic/vagrant-up/R31Bu-enX-k
