8 This program is released into the public domain and can be used by
9 anyone who wants to. Vendors may include it into their distributions
10 if they want to without any restrictions. (Although it would be nice
11 to be notified by email if someone decides to do that, and/or a note
12 somewhere about who wrote this program. Like in the man-page or so.. :-)
14 This is a program that implements the RFC1413 identification server. It
15 was very much inspired by Dan Bernstein's original 'authd' (but unlike
16 that program doesn't use 'netstat' to get some of the information) It
17 uses the kernel information directly. (And is due to that fact a lot
18 faster). Dan has now written another version of the 'authd' daemon that
19 uses his 'kstuff' to read the kernel information. Unlike that daemon,
20 this will use only normally available kernel access functions (and is due
21 to that more limited in the different machines it support). Please note
22 that this daemon used to be called pauthd but has changed name to better
23 reflect what it does (and to conform to the new RFC).
25 This daemon has been tested on the following machines/OS (please report
26 to me if you've tested a newer version, or if your machine/OS isn't among

66 1) HP-UX 7.0 doesn't support running streams based services from
67 Inetd with the "wait" option (and the "-w" flag to Pidentd).
69 It also has problems with starting stuff as user "sys" from Inetd.
70 (It doesn't correctly set the group id to "sys") so I suggest you
71 either starts it as user "root" and use the "-u" and "-g" flags
72 to setuid and setgid itself to user "sys", group "sys", or do a
73 'chgrp sys in.identd' and then a 'chmod g+s in.identd' and start
74 it as user "sys" from Inetd.
76 2) These systems also doesn't support running streams based
77 services from Inetd with the "wait" option.
79 3) See notes in the READMEs/README.<machine-type> specific files.
82 Please let me know if you find any bugs, or have ported it to other
83 machines (and care to share the changes with me and the world!).
85 See the manual page for information about the various command line
86 options that are available.
88 NOTE: One should NOT use the -d option when using it for normal use!
90 If you intend to create or modify daemons that use the IDENT protocol
91 then you may wish to get the "libident" library that contains some
92 functions to implement the client side of this protocol. It is available
93 as "libident-*.tar.Z" in "pub/ident/libs" at "ftp.lysator.liu.se".
95 There is a mailing list for users of the IDENT(RFC1413)/TAP protocol called
96 'ident-users@lysator.liu.se' that you may want to consider joining.
97 Send mail to the address 'ident-users-request@lysator.liu.se' to
98 join it. This list is intended for generic discussions on using this
99 protocol and it's associated tools.
101 If you only want to receive news about new (non-alpha/beta) releases of
102 Pidentd then you can join the 'ident-announce@lysator.liu.se' mailing
103 list. Send mail to the address 'ident-announce-request@lysator.liu.se' to
104 join it. No discussions will take place on this list.
106 I also run a small mailing list for people who wants to act as testers
107 of new alpha/beta-versions of Pidentd. If you wish to join, please send
108 mail to the address 'pidentd-testers-request@lysator.liu.se'. (I can always
109 use more testers, so don't hesitate :-)
111 It's a human (namely me :-) that reads the letters sent to *-request.
112 Please include the full email address to which to wish to have the
115 I'm grateful for success/failure stories about installing/compiling this
118 Information of interrest:
120 1. Machine and operating system type and version.
121 2. Command line flags.
122 3. Inetd.conf configuration.
123 4. Did it work, or not. And if not - what did it report to the
124 syslog file? (You'll have to add the "-l" option and probably
125 reconfigure your Syslogd). If you use the "-d" option then
126 you can see a verbose error if you Telnet into it directly and
127 send it a query manually. (See the INSTALL file for more information).
