Strange, that's all I use to define remote network blocks and it works
fine. The subnet {} definition gets created, but is not tied into a real
shared-network {} block. A commented out shared-network block is created
like so for remote networks, I'm assuming for internal xcat use:
#shared-network !remote! {
Here's what a remote network line looks like that is working correctly
for me:
#netname,net,mask,mgtifname,gateway,dhcpserver,tftpserver,nameservers,ntpservers,logservers,dynamicrange,staticrange,staticrangeincrement,nodehostname,ddnsdomain,vlanid,domain,comments,disable
"cluster1","172.49.1.0","255.255.255.0","!remote!","172.49.1.254","172.28.55.1","172.28.183.101","172.30.251.20,172.31.251.20","172.31.251.5,172.30.251.5","172.28.55.1",,,,,,,,,
Have you re-ran "makedhcp -n" to create a new dhcpd.conf after
configuring your remote network?
