=head1 LOG MESSAGES |
|
|
|
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. |
|

have existed/been created was <fname> the |
|
corresponding URI: <remoteurl> This is emitted in several |
|
places. |
|
|
|
=item Unable to move <transname> to <destname> |
|
|
|
From fetch_user_file_handler - the user file was replicated but could not |
|
be mv'd to its final location. |
|
|
|
=item Looking for <domain> <username> |
|
|
|
From user_has_session_handler - This should be a Debug call instead |
|
it indicates lond is about to check whether the specified user has a |
|
session active on the specified domain on the local host. |
|
|
|
=item Client <ip> (<name>) hanging up: <input> |
|
|
|
lond has been asked to exit by its client. The <ip> and <name> identify the |
|
client systemand <input> is the full exit command sent to the server. |
|
|
|
=item Red CRITICAL: ABNORMAL EXIT. child <pid> for server <hostname> died through a crass with this error->[<message>]. |
|
|
|
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 Famous last words: Catching exception - <log> |
|
|
|
Where log is some recent information about the state of the child. |
|
|
|
=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 |
|
$children{$pid} |
|
|
|
=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. |
|
|
|
=item Free socket: <shutdownretval> |
|
|
|
The HUPSMAN sub was called due to a SIGHUP. all children get killsed, and lond execs itself. |
|
This is followed by: |
|
|
|
=item (Red) CRITICAL: Restarting |
|
|
|
lond is about to exec itself to restart. |
|
|
|
=item (Blue) Updating connections |
|

|
(In response to a USR2). All the children (except the one for localhost) |
|
are about to be killed, the hosts tab reread, and Apache reloaded via apachereload. |
|
|
|
=item (Blue) UpdateHosts killing child <pid> for ip <ip> |
|
|
|
Due to USR2 as above. |
|
|
|
=item (Green) keeping child for ip <ip> (pid = <pid>) |
|
|
|
In response to USR2 as above, the child indicated is not being restarted because |
|
it's assumed that we'll always need a child for the localhost. |
|
|
|
|
|
=item Going to check on the children |
|
|
|
Parent is about to check on the health of the child processes. |
|
Note that this is in response to a USR1 sent to the parent lond. |
|
there may be one or more of the next two messages: |
|
|
|
=item <pid> is dead |
|
|
|
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. |

this should be cause for the child to exit. |
