Hello,

im trying to setup a emulated satellite network using opensand (https://www.opensand.org/index.html) and encountered some problems.
The planned testbed should consist of one emulated satellite, one satellite terminal, and one gateway.
Im using the web interface for configurating each entity (https://github.com/CNES/opensand/blo...y/doc/usage.md).

When launching all entities, the configuration files get deployed to the corresponding machines successfully, however, the machines are unable to launch the entities.
When trying to start the entities manually I get the following error messages:

satellite:
abe9a300.jpg

terminal:
6dd7162a.jpg

gateway:
b95d2081.jpg

It seems to be a problem with the establishment of UDP sockets and channels, however, I'm unaware on how to resolve this issue.
If anyone has a hint or solution for this matter please let me know, I would really appreciate it. Thank you.
