NNTP Server Health Checks
Net News Transfer Protocol (NNTP) is a TCP/IP protocol based upon text strings sent bidirec-
tionally over 7 bit ASCII TCP channels, and listens to port 119. It is used to transfer articles
between servers as well as to read and post articles. NNTP specifies a protocol for the distribu-
tion, inquiry, retrieval, and posting of news articles using a reliable stream-based transmission
of news among the ARPA-Internet community. NNTP is designed so that news articles are
stored in a central database allowing a subscriber to select only those items he wishes to read.
NNTP is documented in RFC977. Articles are transmitted in the form specified by RFC1036.
