The software for Syslog, NTP and SNMP used in EOS resolves hostnames at service start-up. It¡¯s possible that during service operation, the configured host becomes unavailable and the configuration needs to be set to a different host to continue the service. The problem is that such change requires manual restart of the service. Even if the hostname doesn¡¯t change and only the underlying address is updated at the DNS server, the administrator has to manually reset service configuration.
