8 FUD - provide information about user mailboxes
9
11 fud [ -C config-file ] [ -U uses ] [ -T timeout ] [ -D ]
12
14 FUD is a long lived datagram daemon started from master that provides
15 information about when a user last read their mail, when mail last
16 arrived in a user's mailbox, and how many messages are recent for that
17 user.
18
19 Note that for FUD to run properly you must set proto=udp in its
20 cyrus.conf services entry. prefork=1 is also recommended. FUD will
21 automatically proxy any and all FUD requests to the appropriate backend
22 server if it is runing on a Cyrus Murder frontend machine.
23
24 FUD reads its configuration options out of the imapd.conf(5) file
25 unless specified otherwise by -C.
26
28 -C config-file
29 Read configuration options from config-file.
30
31 -U uses
32 The maximum number of times that the process should be used for
33 new connections before shutting down. The default is 250.
34
35 -T timeout
36 The number of seconds that the process will wait for a new con‐
37 nection before shutting down. Note that a value of 0 (zero)
38 will disable the timeout. The default is 60.
39
40 -D Run external debugger specified in debug_command.
41
43 /etc/imapd.conf
44 Default configuration file.
45
46 /etc/cyrus.conf
47 Cyrus Master process configuration file.
48
50 Though not really a bug, FUD will silently ignore any requests that it
51 does not consider valid.
52
53 Also not really a bug, FUD requires that the anonymous user has the 0
54 (zero) right on the mailbox in question. This is only a "bug" because
55 0 is not a standard IMAP ACL bit.
56
57 FUD is an experimental interface meant to provide information to build
58 a finger-like service around. Eventually it should be superceded by a
59 more standards-based protocol.
