Hi There, Did you mean configuring a DNS , NFS, and LDAP servers or you have a server which needs to be configured to have LDAP authentication from per-existing LDAP server? DNS itself can have many things like DNS master/slave/caching/forwarder etc, similar for NFS. Now about firewall commands, you mean configuring OS firewall rules (firewalld/iptables?) Which Linux distribution you have? Share more details please. Thanks,
