nefu (network fidelity utility) is a Unix daemon that monitors services over the network. It uses a "no false alarms" fault verification algorithm, and understands network dependancies. Natively-monitored protocols include ICMP echo (ping), SSH, IPP, DNS, HTTP, POP, NTP, IMAP, SMTP, and LDAP, as well as having facilities to execute external programs. Status pages are available via finger or the Web.
