It should be possible using PS but I have not done so far.

You probably want to call Set-Acl[^] for each single file and directory within a try a catch block (about_Try_Catch_Finally | Microsoft Docs[^]). So errors will not let your script terminate and can be logged.

Using MacMini as host for Internet facing Virtual Box VM's

Thank you for the update. It is always good to find a ready-to-use solution which might be also helpful for others.

Good day all;

I have a Mac Mini Late 2012 with 4GB Ram and i5. The machine is upgraded to 16GB, and might change drive to SSD. I am targeting this machine to be a host machine running Virtual Box on which I will run a Win 10 machine and an Ubuntu Server 16.04. Both these VM’s will be hosting web applications and connecting to the Internet. On Win 10 I will be running IIS and hosting ASP.NET sites. On Ubuntu I have some two PHP/MySQL applications and two other web applications running on own ports (8500 & 8501).

The thinking is that I will route relevant ports to the relevant VM/Port using Virtual Box. My questions:

1. Is this doable with Mac?
2. Do I need to install MacOS Server since the machine will be connected directly to the web?
3. Will I be able to remote into the VM’s directly (eg: ssh into the Ubuntu box)?
4. Will I be able to remote into the Mac to, for example, restart the physical machine or restart Virtual Box?

Thanks

Simple; you don't.

Graphics aren't code, and code that is currently being executed is not directly translatable to "c language".

1) You've posted this in the "System Admin" forum, which is about administering systems. You should have posted it in the Bugs & Suggestions forum, or The Lounge.

2) There is an automated system which uses Bayesian probabilities to decide whether it thinks a post is spam or not. Sometimes, it will flag messages as potential spam for no obvious reason. It's nothing personal; you just have to wait for a human being to review the message and allow it to be posted.

Hi,

I have a simple test application that allows me to send an email message through an Office 365 account. When I run this application from say my home PC it works fine, but when I run it from any machine on my company's network, it doesn't work.

The application allows for two different methods of sending a message, a simple smtp server address and a webservice. When running the application I get a different error for each method:
- smtp server:

Quote:
No connection could be made because the target machine actively refused it

- webservice:

Quote:
Autodiscover service couldn't be located

Our system administrator tells me our firewall is not blocking the port, and has not been able to suggest anything else. We only recently switched from third party Exchange 2010 to Office 365 and our on-premise AD is synced to it. MS Outlook works fine. Our office scanner also cannot send scans to email anymore, which it could through Exchange 2010's smtp server.

I am at a loss, and any help with this issue will be much appreciated.

Regards,
Johan

Try to get the original error message send by the "target" (an SMTP error message or an ICMP message from a router/firewall at the target). It should be helpful.

Hi,

Thanks for your reply. I set the application to specifically show smtp errors, but the error remains the same:

Quote:
System.Net.Mail.SmtpException: Failure sending mail. ~~-> System.Net.WebException: Unable to connect to the remote server -~~> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 40.101.88.18:587

Quote:
(an SMTP error message or an ICMP message from a router/firewall at the target)

The application works fine when I run it on any machine that is not on our network. Wouldn't that suggest that the error is caused by our own network, but somehow is not interpreted as a remote error?
I can ping 40.101.88.18 normally.

Regards,
Johan

That means that there is no service listening on the specified port or a firewall is blocking the request (at the target side). When you can connect from other systems (did you use the same server name and port number 587 there?), it must be a firewall that is blocking requests by the source IP (IP is black listed or not white listed).

40.101.88.18 belongs to Microsoft. Which SMTP server name have you specified?

My first guess was also that the problem is in our firewall, but I only asked our admin about a port being blocked. I will have to ask again about a possible black/white listing. Thanks for that suggestion.

As for the SMTP server, per MickeySoft's instructions I use smtp.office365.com and port 587 or 25. I suppose that address has its own autodiscover protocol. nslookup gives me the specific smtp server name outlook-emeaeast3.office365.com and 9 different IP addresses.

What I have been wondering about is, how MS Outlook contacts exchange online. Why is it not having any problem connecting?

The error message indicates that a target / remote side refuses the connection. This is usually a system behind the first router (the first router should send a different message when he blocks outgoing attempts). I don't think that MS is blocking accesses from your company. Because it works on other sites, it is most probably sourced somewhere in your company network or your companies internet provider.

Many companies block outgoing SMTP except for white listed source IPs (e.g. only a local forwarding SMTP server is allowed to talk SMTP to the net).

The network admin in your company is the responsible person to contact. Even if he tells you that there are no filter rules, he might help better because he should know the toplogy of the company network.
