Appendix. Communication with External Networks

Communications between ABCI and external services/servers are restricted. The permitted communications are:

Source	Destination	Port	Service Name
ANY	Compute nodes Memory intensive node	DENIED	-
Compute nodes Memory intensive node	ANY	22/tcp	ssh
Compute nodes Memory intensive node	ANY	53/tcp	dns
Compute nodes Memory intensive node	ANY	80/tcp	http
Compute nodes Memory intensive node	ANY	443/tcp	https

Especially, for the outbound (compute nodes -> external) communications which are not currently permitted, we will consider granting a permission for a certain period of time on application basis.

For further information, please contact ABCI support if you have any request.
