I don't know whether the svscan startup script is rcng compliant yet, but if it is, you could move it to /etc/rc.d and move it _way_ up in the startup sequence. Another option is to put addresses that need to resolve before svscan has started into /etc/hosts so that they don't need DNS. This could be a maintenance nightmare, though, if there are many addresses. -- Bill Moran Collaborative Fusion Inc. **************************************************************** IMPORTANT: This message contains confidential information and is intended only for the individual named.
