+
+The messages below can be emitted in the lond log. This log is located
+in ~httpd/perl/logs/lond.log Many log messages have HTML encapsulation
+to provide coloring if examined from inside a web page. Some do not.
+Where color is used, the colors are; Red for sometihhng to get excited
+about and to follow up on. Yellow for something to keep an eye on to
+be sure it does not get worse, Green,and Blue for informational items.
+
+In the discussions below, sometimes reference is made to ~httpd
+when describing file locations. There isn't really an httpd
+user, however there is an httpd directory that gets installed in the
+place that user home directories go. On linux, this is usually
+(always?) /home/httpd.
+
+
+Some messages are colorless. These are usually (not always)
+Green/Blue color level messages.

+=item (Red) LocalConnection rejecting non local: <ip> ne 127.0.0.1
+
+A local connection negotiation was attempted by
+a host whose IP address was not 127.0.0.1.
+The socket is closed and the child will exit.
+lond has three ways to establish an encyrption
+key with a client:
+
+=over 2
+
+=item local
+
+The key is written and read from a file.
+This is only valid for connections from localhost.
+
+=item insecure
+
+The key is generated by the server and
+transmitted to the client.
+
+=item ssl (secure)
+
+An ssl connection is negotiated with the client,
+the key is generated by the server and sent to the
+client across this ssl connection before the
+ssl connectionis terminated and clear text
+transmission resumes.
+
+=back
+
+=item (Red) LocalConnection: caller is insane! init = <init> and type = <type>
+
+The client is local but has not sent an initialization
+string that is the literal "init:local" The connection
+is closed and the child exits.
+
+=item Red CRITICAL Can't get key file <error>
+
+SSL key negotiation is being attempted but the call to
+lonssl::KeyFile failed. This usually means that the
+configuration file is not correctly defining or protecting
+the directories/files lonCertificateDirectory or
+lonnetPrivateKey
+<error> is a string that describes the reason that
+the key file could not be located.
+
+=item (Red) CRITICAL Can't get certificates <error>
+
+SSL key negotiation failed because we were not able to retrives our certificate
+or the CA's certificate in the call to lonssl::CertificateFile
+<error> is the textual reason this failed. Usual reasons:
+
+=over 2
+
+=item Apache config file for loncapa incorrect:
+
+one of the variables
+lonCertificateDirectory, lonnetCertificateAuthority, or lonnetCertificate
+undefined or incorrect
+
+=item Permission error:
+
+The directory pointed to by lonCertificateDirectory is not readable by lond
+
+=item Permission error:
+
+Files in the directory pointed to by lonCertificateDirectory are not readable by lond.
+
+=item Installation error:
+
+Either the certificate authority file or the certificate have not
+been installed in lonCertificateDirectory.
+
+=item (Red) CRITICAL SSL Socket promotion failed: <err>
+
+The promotion of the connection from plaintext to SSL failed
+<err> is the reason for the failure. There are two
+system calls involved in the promotion (one of which failed),
+a dup to produce
+a second fd on the raw socket over which the encrypted data
+will flow and IO::SOcket::SSL->new_from_fd which creates
+the SSL connection on the duped fd.
+
+=item (Blue) WARNING client did not respond to challenge
+
+This occurs on an insecure (non SSL) connection negotiation request.
+lond generates some number from the time, the PID and sends it to
+the client. The client must respond by echoing this information back.
+If the client does not do so, that's a violation of the challenge
+protocols and the connection will be failed.
+
+=item (Red) No manager table. Nobody can manage!!
+
+lond has the concept of privileged hosts that
+can perform remote management function such
+as update the hosts.tab. The manager hosts
+are described in the
+~httpd/lonTabs/managers.tab file.
+this message is logged if this file is missing.
+
+
+=item (Green) Registering manager <dnsname> as <cluster_name> with <ipaddress>
+
+Reports the successful parse and registration
+of a specific manager.
+
+=item Green existing host <clustername:dnsname>
+
+The manager host is already defined in the hosts.tab
+the information in that table, rather than the info in the
+manager table will be used to determine the manager's ip.
+
+=item (Red) Unable to craete <filename>
+
+lond has been asked to create new versions of an administrative
+file (by a manager). When this is done, the new file is created
+in a temp file and then renamed into place so that there are always
+usable administrative files, even if the update fails. This failure
+message means that the temp file could not be created.
+The update is abandoned, and the old file is available for use.
+
+=item (Green) CopyFile from <oldname> to <newname> failed
+
+In an update of administrative files, the copy of the existing file to a
+backup file failed. The installation of the new file may still succeed,
+but there will not be a back up file to rever to (this should probably
+be yellow).
+
+=item (Green) Pushfile: backed up <oldname> to <newname>
+
+See above, the backup of the old administrative file succeeded.
+
+=item (Red) Pushfile: Unable to install <filename> <reason>
+
+The new administrative file could not be installed. In this case,
+the old administrative file is still in use.
+
+=item (Green) Installed new < filename>.
+
+The new administrative file was successfullly installed.
+
+=item (Red) Reinitializing lond pid=<pid>
+
+The lonc child process <pid> will be sent a USR2
+signal.
+
+=item (Red) Reinitializing self
+
+We've been asked to re-read our administrative files,and
+are doing so.
+
+=item (Yellow) error:Invalid process identifier <ident>
+
+A reinit command was received, but the target part of the
+command was not valid. It must be either
+'lond' or 'lonc' but was <ident>
+
+=item (Green) isValideditCommand checking: Command = <command> Key = <key> newline = <newline>
+
+Checking to see if lond has been handed a valid edit
+command. It is possible the edit command is not valid
+in that case there are no log messages to indicate that.

+The password for <username> was
+successfully changed.

+
+A lond child terminated. NOte that this termination can also occur when the
+child receives the QUIT or DIE signals. <pid> is the process id of the child,
+<hostname> the host lond is working for, and <message> the reason the child died
+to the best of our ability to get it (I would guess that any numeric value
+represents and errno value). This is immediately followed by

+=item Red CRITICAL: TIME OUT <pid>
+
+Some timeout occured for server <pid>. THis is normally a timeout on an LWP
+doing an HTTP::GET.
+
+=item child <pid> died
+
+The reaper caught a SIGCHILD for the lond child process <pid>
+This should be modified to also display the IP of the dying child

+=item Unknown child 0 died
+A child died but the wait for it returned a pid of zero which really should not
+ever happen.
+
+=item Child <which> - <pid> looks like we missed it's death
+
+When a sigchild is received, the reaper process checks all children to see if they are
+alive. If children are dying quite quickly, the lack of signal queuing can mean
+that a signal hearalds the death of more than one child. If so this message indicates
+which other one died. <which> is the ip of a dead child
+
+=item Free socket: <shutdownretval>
+
+The HUNTSMAN sub was called due to a SIGINT in a child process. The socket is being shutdown.
+for whatever reason, <shutdownretval> is printed but in fact shutdown() is not documented
+to return anything. This is followed by:

+=item Red CRITICAL: Shutting down
+
+Just prior to exit.

+The HUPSMAN sub was called due to a SIGHUP. all children get killsed, and lond execs itself.

+Parent is about to check on the health of the child processes.

+
+A child that we have in our child hash as alive has evidently died.
+
+=item Child <pid> did not respond
+
+In the health check the child <pid> did not update/produce a pid_.txt
+file when sent it's USR1 signal. That process is killed with a 9 signal, as it's
+assumed to be hung in some un-fixable way.

+
+=item Unable to determine who caller was, getpeername returned nothing
