If you have configured a Redhat 6 machine to use DHCP and you are required to send the DHCP server a hostname there is no provision in /etc/sysconfig/network-scripts/ifup do do so. My work around was to replace, in ifup: if /sbin/pump -i $DEVICE ; then with if /sbin/pump -h `hostname` -i $DEVICE ; then Very may DHCP sites would be set up so this is required, I believe. regards, john
In initscripts-4.32 (will be in next rawhide), just set the 'DHCP_HOSTNAME' variable in /etc/sysconfig/ifcfg-<device>, and ifup will pass this to pump.
