can't contact newserver news.gmain.org

[Richard E Miles]

I was trying to contact the news.gmain.org newsserver but was unable. I
typed slrn -nntp -h news.gmain.org --create. It said:
Reading startup file /etc/slrn.rc.
Using newsrc file /home/rmiles/.jnewsrc for server news.gmain.org.
Connecting to host news.gmain.org ...Failed to resolve news.gmain.org
slrn fatal error:
Failed to initialize server.

How do I use this news service? 
I also did a ping news.gmain.org and got unknown address.
