In the outline below, my Windows PC is named ineke and I use an account named bill on the Mac and a local account named bill on Windows. Very similar, make sure you exercise care when creating firewall rules.Sharing my solution, as it cost some effort and there were some non-obvious steps. Your VM should now receive incoming traffic if the rule was correctly specified.
Put a description (can be anything that describes the purpose of your rule).Under Rule * Select the protocol, the next example assume you use the option Custom TCP Rule.To create a rule to allow incoming traffic to port 1280/tcp do the following. Security rules (firewall rules) that are applied for your VM from the OpenStack’s network functions. To select the checkbox on the left of it and click on Manage Rules on the right to see all your Normally there is only one that is called default. On the left, look for the menu Network and click on it, then click on Security Groups. To allow this traffic execute the following steps: However the VMs are still accessible all over campus so it’s always good practice to exercise care on services listeningīy default any incoming connection to most ports are not allowed, to create a rule (using the port 1280/tcp as an example) The Computer Science OpenStack Cluster’s networking runs using a Private IPv4 subnet, this means that external networkĪccess (Internet) it’s not allowed directly to the VMs, and this protects the VMs further from internet attacks, etc., Make sure you don’t expose any sensitive or private information from your application (the one listening on the network port) This setting and many more can be configured in an sshĬonfiguration file an example is included below.Ĭreating a firewall rule could lead to unauthorized access to non-secured applications that are listening on a socket. Now you can run graphical applications on your VM and see them on
Receive forwarded X Windows connections over SSH, add -Y as a flag to the If you are connecting from a machine running an X server able to SSH has the advantages of speed and accessibility, but it lacks a graphical user The check and create a new entry for your VM. Is the line we need to remove from that text file, in this way our ssh client will not fail Then it’s safe to edit the file (in this case) /Users/username/.ssh/known_hostsĪnd as can be seen line 1 ( Offending ECDSA key in /Users/username/.ssh/known_hosts:1)
Of the semester, if this happens the first time you are connecting to it This is normally due to the fact that your VM was recreated at the start Offending ECDSA key in /Users/username/.ssh/known_hosts:1 ECDSA host key for linkblue.cs.uky.edu has changed and you have requested strict checking. Add correct host key in /Users/username/.ssh/known_hosts to get rid of this message. Please contact your system administrator. WARNING: POSSIBLE DNS SPOOFING DETECTED! The ECDSA host key for linkblue.cs.uky.edu has changed, and the key for the corresponding IP address 172.31.112.111 is unknown.
