Dear all,
I noticed in syslog that i receive authentication failure from cron:
How can I check what caused that and why there are two "crons"?
There are also other cron entries in syslog:
Recently i had issue with dovecot/postfix mailuser rights, maybe this could be the issue, but i do not know what to look for.

Hi,
I am using gmake to compile a c program with a makefile. The make file runs ld. I get the following error

My PAM module seems to work right but it fails in authentication. Althought it can't authenticate, the session module works and the software who uses it executes well.

Ssh connections using shared public keys issue “authentication failure” messages, then succeed with “session opened”.
I have found a few other threads with similar issue, but no solutions offered. :wall:
How can I eliminate the failure messages?

Dear All,
I have Google Two Factor (2F) Authentication enabled for sshd on most of my Linux servers. This works well and I highly recommend it.
My question is:
Has anyone set this up for rsync which runs in a crontab?
For example, supposed we have this simple crontab script:

cron
CRON(8) BSD System Manager's Manual CRON(8)NAME
cron -- daemon to execute scheduled commands (ISC Cron V4.1)
SYNOPSIS
cron [-n] [-x debugflags]
DESCRIPTION
cron is normally started during system boot by rc.d(8) framework, if cron is switched on in rc.conf(5).
It will return immediately so you don't have to start it with '&'.
cron searches /var/cron/tabs for crontab files which are named after accounts in /etc/passwd. Crontabs found are loaded into memory. cron
also searches for /etc/crontab which is in a different format (see crontab(5)). Finally cron looks for crontabs in /etc/cron.d if it exists,
and executes each file as a crontab.
When cron looks in a directory for crontabs (either in /var/cron/tabs or /etc/cron.d) it will not process files that:
- Start with a '.' or a '#'.
- End with a '~' or with ``.rpmsave'', ``.rpmorig'', or ``.rpmnew''.
- Are of zero length.
- Their length is greater than MAXNAMLEN.
cron then wakes up every minute, examining all stored crontabs, checking each command to see if it should be run in the current minute. When
executing commands, any output is mailed to the owner of the crontab (or to the user named in the MAILTO environment variable in the crontab,
if such exists).
Events such as START and FINISH are recorded in the /var/log/cron log file with date and time details. This information is useful for a num-
ber of reasons, such as determining the amount of time required to run a particular job. By default, root has an hourly job that rotates
these log files with compression to preserve disk space.
Additionally, cron checks each minute to see if its spool directory's modtime (or the modtime on /etc/crontab or /etc/cron.d) has changed,
and if it has, cron will then examine the modtime on all crontabs and reload those which have changed. Thus cron need not be restarted when-
ever a crontab file is modified. Note that the crontab(1) command updates the modtime of the spool directory whenever it changes a crontab.
The following options are available:
-x This flag turns on some debugging flags. debugflags is comma-separated list of debugging flags to turn on. If a flag is turned on,
cron writes some additional debugging information to system log during its work. Available debugging flags are:
sch scheduling
proc process control
pars parsing
load database loading
misc miscellaneous
test test mode - do not actually execute any commands
bit show how various bits are set (long)
ext print extended debugging information
-n Stay in the foreground and don't daemonize cron.
Daylight Saving Time and other time changes
Local time changes of less than three hours, such as those caused by the start or end of Daylight Saving Time, are handled specially. This
only applies to jobs that run at a specific time and jobs that are run with a granularity greater than one hour. Jobs that run more fre-
quently are scheduled normally.
If time has moved forward, those jobs that would have run in the interval that has been skipped will be run immediately. Conversely, if time
has moved backward, care is taken to avoid running jobs twice.
Time changes of more than 3 hours are considered to be corrections to the clock or timezone, and the new time is used immediately.
SIGNALS
On receipt of a SIGHUP, the cron daemon will close and reopen its log file. This is useful in scripts which rotate and age log files. Natu-
rally this is not relevant if cron was built to use syslog(3).
