How to setup dynamic hostname?
I am trying to install Matlab on my fedora 22. The matlab-installation is not a big deal, but the case is, that I have to install it from a server at school. The school has provided me with a license-file, and I also has the key. To complete the installation, I have to be connected to the VPN for my school.
The problem is that matlab can't finde the right host, even though I am connected directly to the schools VPN or Wifi.
Running $ uname -n gives me localhost.localdomain
When I try to start the license manager, I get this:
Checking license file for local hostname and local hostid . . .
Error: Your host does not match any SERVER line in your license
file. Your local lmhostid(s) are:
681729a05df2 28d2441cf2fc
Your hostname is: localhost.localdomain
The SERVER line(s) are:
-----------------------------------------------
SERVER donau.hiof.no 27000
-----------------------------------------------
Please stop, fix the problem, and try again . . .
Continue to start up license manager? y/[n])
How can I make my hostname change automaticly from one network to the next?
You can try
hostnamectl set-hostname --transient $some-hostname- this would have the same effect as if your school's dhcp server provided a hostname, which meets your expectation of the hostname changing with the network. However, matlab might not be looking there, so you might have to change your hostname globally (without--transient) for it to work.I will try that out. But another problem have, is that I don't know how to enter a location on the server. In windows I use the fiie explorer, but how do I enter this location in fedora, or any linux system? The location is: \donau.hiof.no\CD_image
You should be able to use the equivalent file browser on Fedora to access files; unless you are doing something unusual it will be very straightforward. That said, please open a different question for different issues.
