RE: GEM distribution

Bonjour Anne-Marie and Michel,

We, Unidata, are being denied access to:

ldm-wxo.cmc.ec.gc.ca

199.212.17.24

Did you execute a "ldmadmin restart" after making the changes in
ldmd.conf for us to gain access?

Could there be firewall issues at play?

Thanks for your efforts, it is appreciated!

Jeff
