Node:Description of gnatsd, Next:gnatsd options, Up:gnatsd
gnatsd network daemon is used to service remote GNATS
requests such as querying PRs, PR creation, deletion, and editing, and
miscellaneous database queries. It uses a simple ASCII-based command
protocol (similar to SMTP or POP3) for communicating with remote
It also provides a security model based either on IP-based
authentication (generally considered very weak) or username/passwords,
where passwords may be in cleartext, UNIX crypt or MD5 hash format.
gnatsd is granted according to certain predefined
access levels. Access levels are further discussed in Controlling access to databases. It should be emphasized that
security has not been a focus of development until now, but future
versions are expected to address this more thoroughly.
All of the GNATS clients are capable of communicating via the GNATS remote protocol to perform their functions.
gnatsd is usually started from the inetd facility and should run as
gnats user (the actual username of this user is configurable
during installation, see Configuring and compiling the software for details.)
