Networking on nodes
Login nodes:
All login nodes have direct outbound and opened access to whole internet and all protocols via nodes’ public IP and appropriate gateway
The dual stack is available on these nodes (meaning both IPv4 and IPv6 connectivities are available independently)
Compute nodes:
Compute nodes have full opened access to license servers needed by various software
if a user can’t contact a license server, from compute node they could try to run
nmap -p 1234 mylicenseserver.comwhere “1234” is the port mylicenseserver.com should listen onif output of the command above yields anything else than open state, there are 2 potential problems - see below.
1. The license server is not configured properly:
Please ensure it’s listening on the right port and it’s opened for incoming connection from the following ip ranges:
| Cluster Name | Public login | Public service |
|---|---|---|
| SAGA | 158.36.42.32/28 2001:700:4a01:10::/64 |
158.36.42.48/28 2001:700:4a01:21::/64 |
| BETZY | 158.36.141.144/28 2001:700:4a01:25::/64 |
158.36.154.0/28 2001:700:4a01:23::/64 |
| OLIVIA | 158.38.122.192/27 2001:700:570f:50::/64 |
158.38.122.224/27 2001:700:570f:51::/64 |
If this is in place and user still can't contact the license server from a compute node, please contact `support@nris.no` and we will add the license server on our side.
2. You may need to use a proxy
Compute nodes have limited access whole internet, it means a uses is allowed to reach http and https services via a proxy server. Users can check the proxy server setup by running env | grep -i proxy which should spit out the name of proxy server
