Without having access to the router, I do not see this happening. first you have to think about the network, your public server sits on one side of the firewall, and has a public IP address. then the server you want to have serve up some of the pages is on the inside of the firewall and has a non-public IP address. Unless you can access the ...

I am assuming you are referring to your external IP address assigned by your ISP. If you already have a domain at no ip you simply need to configure dynamic DNS in your router/firewall and forward the necessary ports (80 & 443) for your web server to the internal IP address of your web server. Typically to log into your firewall you look for the ...

I had the same symptoms while trying to start vsftpd on an Ubuntu 16.04. In my case it was enough to comment out this line in /etc/vsftpd.conf: listen_ipv6=YES I don't know why i does not work with ipv6 for me, but I have no need for IP-v6 and disabling it solved the problem in my case.

The solution should not be to replace your custom config.php owncloud configuration file, with the default one. By doing that, you have turned off additional settings you have made, like caching. Problem here is that you have upgraded OS version and, also, PHP version, among other stuff. REDIS PHP extension is compiled for an earlier version of PHP and ...

Adding to Barafu's answer: from what I understand of the whole setup, the vbox driver is rebuilt for each version of the kernel you have. There is a linux-headers-* package for each version of the kernel you have in /boot. Normally getting these should be fairly automatic: linux-generic depends on linux-headers-generic that depends on linux-headers-{kernel ...

According to the error text, you have not kernel headers installed. The package name should be something like linux-headers.

You need no "extra" packages to make any Linux machine work as a server. Just install the packages you want this machine to serve. For example: If you want this machine to serve web-pages, the basic packages to install are apache2 or lighttpd, depending on your needs. A quick google search will come up with plenty of tutorials on anything you can imagine. ...

You can add your user account to a group with the following command: sudo usermod -a -G <group> <username> Do take care not to forget the -a (append) switch this tells usermod to add the group to the groups your user is already in otherwise it would replace all your existing groups with this one. Note that the groups are read at user login ...

In this case I'd suggest that you use the following command on the machine without internet: apt-get --print-uris --yes install build-essential | grep ^\' | cut -d\' -f2 >downloads.list This will produce an output file in the current directory called downloads.list containing the download URL for all the packages apt needs to install the ...

I'd suggest changing the NAT adapter to a network bridge adapter. NAT means it is essentially using the IP of your host, which in this case is 192.168.1.10. From there, Virtualbox will act as a router. Setting it to network bridge adapter will connect the virtual machine to your "real" network.

"No MTA installed" means that in your script, you might want to send an email, but no MTA (Mail Transfer Agent) have been specified. The cron daemon tries in fact to send outputs to you. You can install an MTA (like postfix), or, if outputs are not important, redirect to" /dev/null 2>&1"

There is no way to use Shared Clipboard functionality as you think between the Mac and the VirtualBox VM directly. Ubuntu Server does not implement a clipboard function on a default (and I don't know if you even can). This prohibits your use of the clipboard in the manner you're trying to achieve. The only way to achieve this would be to SSH from your ...

if you run 'netstat' as superuser: sudo netstat -tulpn | grep 80 That should show you the process that is using port 80 which might help you along. Without further info it does sound like maybe Gitlab is already using port 80, on my Gitlab installation it uses nginx on port 80 by default. Did you maybe do a re-install of Gitlab at some point?

I had a similar problem, messed around for hours and hours until I found Pritunl (https://github.com/pritunl/pritunl), it uses OpenVPN but takes care of all the iptables headache that is needed for the routing you want and gives you a nice web GUI to manage clients, etc. Not the answer you might be looking for, but for me it was a pragmatic solution, ...

Edit: upon re-reading your question I surmise that your server is behind a firewall that you do not control? If so, please disregard the iptables part of the answer and skip to the SSH config part... Is it a matter of wanting the transport to be encrypted, or is it simply a matter of getting through the firewall? Getting through the firewall could be as ...

IPv6 is designed to autoconfigure in many cases. The command ip -6 show addr will show any configured IPv6 addreses. Addresses starting with fe80:: are link local addresses and won't be routed to the internet. The address(es) you are interested in will end with /128. The addresses ending /64 are networks you are connected to. To test connectivity try a ...

I would recommend using the "minimal" or "netinstall" ISO, which will download and install only a core system, plus the packages you select. If I recall correctly, it does not include some of the more "server"-y stuff that Ubuntu Server includes. Since it downloads packages on-the-fly, there won't be a boatload of updates to install once you boot into your ...
