I’m currently setting up server inside our lab at Uni that will be used for multiple purposes including a bibliography database and a CI Server (Jenkins). In order to maintain clean separation of concerns, I have a jailed virtual host for each function along with an assigned internal domain name. Inside the lab, the arrangement works fine.
However, in order to connect to our lab from home, we need to first VPN into the Uni and then SSH into our lab’s gateway machine. From the gateway we can access any internal machines we need to reach, and use SSH Tunnels as needed.
I’m wondering if it is possible to access virtual hosts through a single SSH tunnel? Like Server Name Indication (SNI)? Or would I need to setup a proxy server like Squid? I gather that both DNS as well as HTTP traffic would need to be routed correctly. Can this be done using just
hosts file settings?
Any advice would be much appreciated. Thanks!
I am trying to access multiple websites that I have on my virtual-box server setup(Ubuntu 18.04.2) to my host machine(Ubuntu 19.04). the websites works fine in the virtual environment but when I try to access them in host machine via IP address(192.168.1.13), only files inside
/var/www/html folder are accessed and are accessible on LAN.
BUT I have failed to find a way to access files inside (for instance)
/var/www/test. Is there any sort of simple way to resolve the issue?
Have just upgraded online from 18.10 to 19.04 (desktop 64 bit). BOINC has worked previously but now won’t run. BOINC Manager is greyed out and shows ‘connecting to localhost’. Trying ‘boincmgr’ always returns ‘can’t connect to local host’. It has been suggested that it’s a firewall problem, but gufw doesn’t have a profile for BOINC. Since this is only since upgrade could this be a Ubuntu 19.04 problem?
I am deploying an instance of Security Onion to a test environment. In order to test OSSEC, I stood up an Ubuntu Linux host with assigned IP of 192.168.200.4 and installed the OSSEC agent. Following configuration, I confirmed that the OSSEC agent instance was successfully added to the OSSEC server on the Security Onion instance by running
$ sudo /var/ossec/bin/agent_control -l Wazuh agent_control. List of available agents: ID:000, Name: user-virtual-machine (server), IP: 127.0.0.1, Active/Local ID:002, Name: 001, IP: 192.168.200.4, Active
Using Wireshark, I confirmed that communication was occurring as expected and that the Ubuntu host was regularly sending logs to the server.
I altered a file in /etc on the Ubuntu host which should produce an alert, and it would appear that this change was successfully flagged and an alert was successfully displayed in Squert on the Security Onion Instance.
Squert dashboard filtered on 192.168.200.4 showing integrity alert
However, when I try to visualize alerts using Kibana on the Security Onion instance, my host running OSSEC does not appear as a monitored OSSEC instance at all. Only one device is listed as a monitored host, and that is my Security Onion instance.
Kibana dashboard, please note the sensor count and device count of 1
I’ve attempted to restart the Security Onion service and the host but have not been able to resolve this problem. I am new to Security Onion, so if I am fundamentally misunderstanding how this data should be displayed I apologize. Any help would be greatly appreciated.
I want to share files between an app on a native Windows 10 and an app on virtualized Ubuntu on VMware Workstation Pro, but can’t mount the Windows 10 shared directory onto Ubuntu with this Linux command:
sudo mount -t cifs //192.168.7.24/demo /home/movano/Desktop/share/ -o username=me,uid=me,password=pw
However, a 2nd laptop running Ubuntu 18.04 natively can mount the same directory on the same Windows 10 laptop OK. So, the problem is not on Windows. Samba smb.conf
Installed VMware Workstation Pro onto Windows 10 and virtualized Ubuntu 18.04
Installed Samba on the virtualized Ubuntu with these commands:
sudo apt install samba -y
sudo systemctl restart smbd
This newly installed smb.conf is identical to the smb.conf on the 2nd laptop with native Ubuntu, which of course also has Samba.
Have tried Network Adapter NAT, bridge, and host-only, but all get same problem.
Is it possible to list 2 different directories, each with their own different username/password in the same documentroot in the same virtual host conf?
Ultimate goal is to browse to: https://myservershostname and it displays 2 directories, dir1 and dir2, if you click on dir1 you can only get into it if you type the password for user1, and if you click on dir2 you can only get into it if you type the password for user2.
my non-working config:
<VirtualHost *:443> DocumentRoot "/app/httpd/home/htdocs/" ServerName myservershostname <Directory "/app/httpd/home/htdocs/"> Options Indexes FollowSymLinks </Directory> <Directory "/app/httpd/home/htdocs/dir1/"> AuthType Basic AuthName "Restricted Content" AuthUserFile /etc/httpd/.htpasswd Require user user1 </Directory> <Directory "/app/httpd/home/htdocs/dir2/"> AuthType Basic AuthName "Restricted Content" AuthUserFile /etc/httpd/.htpasswd Require user user2 </Directory> </VirtualHost>
Currently when I browse to https://myservershostname it doesn’t list anything. Any input or resources to look at would be very appreciated
Would it be easier to apply for a UK visa if there is a host family to sponsor for you in going there?
Whether using UDP or TCP, guest VM to guest VM bandwidth on a single Citrix 7.6 XenServer host caps out at about 6Gbits/sec. Would this 5Gbps be comparable to Amazon AWS Xen performance? Need this to much faster for iSCSi performance reasons.

I’m using Ubuntu 18.04.2 LTS, kernel version 4.15.0-47-generic. In the office we have a public wifi hotspot. However, when I connect, I have to accept some terms and conditions before I can use the internet. This does not work on Ubuntu though, I get an “No route to host” error message for this page.
- It works when I reboot and accept the terms and conditions in Windows, then reboot again to Ubuntu. I can directly connect.
- For other wifi hotspots (at the airport or hotels) I don’t have this problem. So this only occurs for this one wifi hotspot.
- I’ve already checked the URL for the login page I get forwarded to, which is correct.
- I’ve tried setting DNS servers manually in
nm-connection-editor (using the DNS hosts that are used on my Windows machine for this hotspot), without success
- I’ve tried
sudo dpkg-reconfigure resolvconf, without success
What can I do to find and fix the issue such that I can login and connect on this wifi hotspot as well?
Mouse doesn't work in the guest OS (Ubuntu 14.04.2) on Virtual Box (installed on MAC OS X)
My situation is the host and guest OS swap, Will the above solution. work?
