Crond ERROR (getpwnam() failed)
Столкнулся сегодня с ошибкой в работе системного Cron. Текст ошибки совершенно не информативный, так что не понятно, в чем конкретно проблема. Начал разбираться самостоятельно, так как по выдаче гугла понял, что причин этой ошибки может быть масса. В итоге нашел решение при проверке /etc/crontab, который использовал для запуска периодических команд.
Началось все с того, что заметил проблемы с очисткой индексов elasticsearch с помощью curator. Он просто ничего не чистил и индексы распухли, заняв почти все место на диске. Пошел в консоль сервера смотреть, в чем проблема. Ручной запуск curator отработал, удалив устаревшие индексы. Стало понятно, что он просто не запускался. В /etc/crontab было правило на регулярный запуск.
Стал смотреть лог cron и нашел там ошибку:
По тексту совершенно не понятно, в чем проблема. Быстро заглянув в гугл, понял, что однозначного ответа на причину ошибки не видно. Пошел еще раз смотреть crontab и понял, в чем проблема. Так как использовался системный cron, в нем надо указать имя пользователя, от которого будет работать команда. А я это забыл сделать. Должно быть так:
Пользователя root я забыл указать, поэтому и была ошибка исполнения. Не понятно, почему нельзя было нормально обработать эту ошибку и вывести ее в лог. Ведь очевидно же, что пользователя /usr/bin/curator в системных пользователях просто нет.

php error getpwnam failed- How we fix it!!
Oops!! Frustrated with (php) (getpwnam failed()) Cron error? We can help you with it.
php error getpwnam failed occurs due to missing entry in crontab file under /etc/cron.d.
At Bobcares, we often get requests regarding cron, as a part of our Server Management Services.
Today, let’s see how our Support Engineers fix this cron job fail for our customers.
Why and when a cron?
Cron jobs are mainly used for scheduling activities, either as recurring tasks or one-time events.
Repetitive tasks can be automated easily using cron jobs.
Cron simplifies the scenario where we need to execute tasks at an interval or at a specific time.
Our Engineers always suggest cron for such scheduled tasks for saving our customer’s valuable time.
But, we may face some errors while handling cron. Today, we are going to discuss in detail on one such error.
How we fix (php) (error getpwnam() failed)?
Recently, one of our customers approached us saying that he is getting an error like the one shown below when cron is executing.
He also mentioned that, while executing the files one by one manually, it is executing perfectly without any problem.
So, our Support Engineers checked in detail and found that this error occurs because the customer missed adding an entry in the cron file.
That is, the customer is trying to run a cron job entry defined in a user crontab file under /etc/cron.d without specifying the username.
So, we corrected the cron file by adding the username and the final cron is in the format as shown below:
Finally, this fixed the problem.
[Need assistance to fix cron job errors? We’ll help you.]
Conclusion
In short, we discussed in detail on php error getpwnam() failed and found that failure in specifying the username leads to this error. Also, we saw how our Support Engineers fix this for our customers.
PREVENT YOUR SERVER FROM CRASHING!
Never again lose customers to poor server speed! Let us help you.
Our server experts will monitor & maintain your server 24/7 so that it remains lightning fast and secure.

Daily cron errors: getpwnam() failed
Daily cron errors: getpwnam() failed
Post by warlord » 21 May 2019 12:46
Hi,
I recently installed 4.x on a CentOS 7.6 system using the build.bash script. On the first run I got a set of errors from missing files (unfortunately I deleted these). However, the daily logwatch is showing persistent cron script errors:
**Unmatched Entries**
ERROR (getpwnam() failed)
ERROR (getpwnam() failed)
I have not yet tried to debug this.

i am not sure if it will works with centos 7.6,
i=ve been developing it with the guys on centos 7.0 and do have 4 on productions.
so i beleive your issue is your centos version.
Re: Daily cron errors: getpwnam() failed

CentOS 7.0 is from June 2014, which means it is 5 years old. You can’t even install EL7.0 today if you wanted to — none of the repos contain it anymore. Even 7.6 is relatively old (October 2018, so 8 months old).
I hope that you’re not saying that you intend to only support a 5-year-old centos release in the upcoming 4.0?

/usr/sbin/crond is from cronie-1.4.11-20
/usr/sbin/CROND does not exist
A little more digging (and googling) took me to https://stackoverflow.com/questions/418 . -from-cron which then pointed me to /etc/cron.d/certbotrenew which is broken. Looking at that file, is contains:
Specifically, it is missing a ‘user’ before the ‘python’. So that is the solution to TWO bugs here:
1) it’s the solution to this one, and
2) it’s the solution to why certbot isn’t being run, because the cron.d entry is broken.

Не работают агенты через cron
Установил на чистый сервер Bitrix virtual appliance version 7.4.3
CentOS Linux release 7.8.2003 (Core)
Агенты при этом не выполняются. Дополнительно добавил задание в крон по инструкции https://dev.1c-bitrix.ru/learning/course/?COURSE_ID=43&LESSON_ID=2943
Но агенты не выполняются, проверяют через Настройки > Настройки продукта> Агенты.
Подскажите пожалуйста, как исправить?
Крон 100% отрабатывает. Проблема не в нем. Пробовал добавить в /home/bitrix/www/local/php_interface/cron_events.php строку с mail() php, письмо по запуску с cron пришло. Что-то с выполнением периодических агентов. Проблем с письмами нет, настроено.
указать
define(«BX_CRONTAB_SUPPORT», true);
define(«BX_CRONTAB», true);
Возможно вы не полностью настроили выполнение ВСЕХ агентов на кроп. А для почты достаточно просто
указать
define(«BX_CRONTAB_SUPPORT», true);
define(«BX_CRONTAB», true);
вот что там. должно быть
*/1 * * * * /usr/bin/php -f /home/bitrix/www/bitrix/php_interface/cron_events.php
*/1 * * * * /usr/bin/php -f /home/bitrix/www/bitrix/modules/main/tools/cron_events.php

не помогает. Агенты замерли, хоть крон и отрабатывает задачи.
На днях продлили лицензию битрикса и обновили, в том числе vmbitrix и php до 7.4.16. После чего перестал работать крон.
В логах была ошибка
Почта настроена. Отправка через mail() происходит.

User in passdb, but getpwnam() fails!
I asked this question on stackoverflow and realized I might get better responses here.
Attempting to set up Samba + OpenLDAP using nss_ldap uner Linux. Alls software is compiled by me from source so no RPMs, YUM, etc.
Using Pozix Linux which is our own distribution — vanilla login system meaning out of the box the distro relies on standard /etc/passwd, /etc/group.
Installed all necessary software to convert system to an LDAP based system which seems to work with other software such as SSH except SAMBA.
Was able to join Windows7 to Samba stand alone PDC, I can not login with a domain account unless that account is also added to the /etc/passwd file.
I get: user in passdb, but getpwnam() fails!
Everything I’ve read points to an NSS_LDAP issue. Here is a list of things I’ve done:
- getent passwd shows users perfectly fine
- I am able to ssh into the same Linux host using a user account that is only in the LDAP database.
- id test (test is my test account only in LDAP) that works
- ./pdbedit -Lv test works
- ./net rpc rights list accounts -Uroot works, I see root has all necessary rights
- per suggestion from stackoverflow, I changed my nsswitch.conf file from (files ldap) to (ldap files) which essentially changed the dump order of getent passwd & didn’t resolve the issue.
- commented out rootbinddn and add the bindpw with clear-text version of the password to eliminate any questions with ldap.secret
- smb.conf has ldapsam:trusted = yes
- smb.conf and ldap.conf both have ssl off a
- Not running nscd
Everyting on the samba.org site chapter-5 about making users happy works except for:
./smbclient //tsrvr/test -Utest
This produces the subject error message in log.smbd and ldap debug log shows a query for test with no errors and a successful return value.
If I put ‘test’ into /etc/passwd, then it works!
It’s as if the relationship between nss_ldap and smbd is broken and I stress relationship because LDAP appears OK (slapcat, ldapsearch, etc. all work). It appears that nss_ldap library is getting a return value that when handed back to smbd, it somehow is not understood.
I would really appreciate any suggestions. I see this problem listed often. Often related to PAM but I’m not using PAM.
Additionally, if I crack open the /etc/passwd file and add a line for the user in question, I can then login.
I’m not using PAM. I added the two Windows7 registry updates required per the Samba.org site.
Software stack is as follows: Samba 3.5.3 OpenLDAP 2.4.21 nss_ldap 264
I began looking at Samba source code.
I found this function in samba3/auth/auth_util.c (about line 580)
pwd evaluates to NULL even though username is valid. getpwnam_alloc allocates memory for result structure and fills it with the Unix UID, primary GID, etc.
Everything I read says that this call uses NSS. I hope someone from Samba team who has knowledge of this than I can chime in.
———————[ update ]——————— Examining samba source code here is what I’m discovering:
The failure is happening in auth/auth_util.c (line 580) with a call to getpwnam_alloc
getpwnam_alloc attempts to do some sort of caching and if the username is not found in recent cache the code falls through with a call to:
sys_getpwnam found in lib/system.c which is just a wrapper for getpwnam
Doesn’t appear as of Samba checks the errno described; will add some debug and report back.
Definitely a failure to the OS library implementing getpwnam but not sure what yet.

Description of problem: Error message "ERROR (getpwnam() failed)" when no user specified for jobs in /etc/crontab is not so helpful at the first. Maybe it will be more nice to have something like "no/wrong user-name specified for this job", or similar. Steps to Reproduce: Put some job in /etc/crontab without "user-name" */1 * * * * echo "bla" > /tmp/bla Actual results: Error message : Error message "ERROR (getpwnam() failed) Expected results: Error message : no/wrong user-name specified for this job

You've actually specified an user - user 'echo'. And the user name is part of the message - see the 'echo' here: Sep 8 14:53:01 vespa crond[1023]: (echo) ERROR (getpwnam() failed) The reason why the getpwnam() failed can be various, it can be also that remote user identity server does not answer to queries. So the message could be: getpwnam() failed - user unknown or user identity resolution failure

As this bug doesn't seem to conform to RHEL-7 bug threshold, but is still an issue in RHEL-8, this bug will be evaluated for a fix in RHEL-8.

Moving this bug to Fedora, as it's been lacking enough priority for inclusion into RHEL for long time. While it still is a valid issue to be fixed, it's not probable it gains enough priority soon, so rather moving to Fedora and also porting it to upstream as https://github.com/cronie-crond/cronie/issues/68. If there are some more significant business reasons why we should prioritize it more, let us know, please.

This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle. Changing version to 34.

This message is a reminder that Fedora Linux 34 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 34 on 2022-06-07. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '34'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 34 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed.
Problem
Cron job fails to run because of missing username to run the job in crontab file under /etc/cron.d
Symptom
Cron job does not run and cron log reports the following error messages repeatedly:
ERROR (getpwnam() failed): No such file or directory
The failed crond job blocks RTM from graphing the data properly.
Cause
The error message is misleading, the actual root cause is the username in the cron job entry is missing.
Diagnosing The Problem
The entry of the cron job looks like this in /etc/cron.d/<filename>:
* 12 * * * /usr/bin/php /scripts/forRTM/scripts/collector1.php
The manual run of the script complete without any error
/usr/bin/php /scripts/forRTM/scripts/collector1.php
But for a cron job entry defined in a user crontab file under /etc/cron.d, it requires a username to run the job
* 12 * * * <username> <command/script> <parameters>
Resolving The Problem
Add a proper username fixes the issue.
* 12 * * * apache /usr/bin/php /scripts/forRTM/scripts/collector1.php
