Package: cron Version: 3.0pl1-137 Severity: important X-Debbugs-Cc: feedb...@ventrilo.com
Dear Maintainer, If an entry in the crontab or a file in the cron.d folder has a username that does not currently exist on the system, the entire crontab file will go unprocessed. The following 4 lines of example cron script can be used to prove the problem. */1 * * * * root touch /tmp/ct1 */1 * * * * root touch /tmp/ct2 */1 * * * * bogus touch /tmp/ct3 */1 * * * * root touch /tmp/ct4 Add these 4 lines to any location in your /etc/crontab file and wait till the clock advances to the next minute. If they work you should have 4 files in the /tmp folder with the names ct1 thru ct4 with the current timestamp. However, due to the 3rd entry using a bogus username none of the lines will work implying the entire file is going unprocessed. If you comment out the line with the bogus username and wait for a minute the files ct1/2/4 will be touched accordingly each minute. If you uncomment the bogus entry none of them will update. I discovered this bug while setting up a test ubuntu web server and then decided to test it on Debian 10, which did have the same problem. Debian 11 also has the problem. Sincerely, Brian Knapp -- Package-specific info: --- EDITOR: --- /usr/bin/editor: /usr/bin/nano --- /usr/bin/crontab: -rwxr-sr-x 1 root crontab 43568 Feb 22 2021 /usr/bin/crontab --- /var/spool/cron: drwxr-xr-x 3 root root 4096 Jan 10 09:51 /var/spool/cron --- /var/spool/cron/crontabs: drwx-wx--T 2 root crontab 4096 Feb 22 2021 /var/spool/cron/crontabs --- /etc/cron.d: drwxr-xr-x 2 root root 4096 Jan 10 09:55 /etc/cron.d --- /etc/cron.daily: drwxr-xr-x 2 root root 4096 Jan 10 09:56 /etc/cron.daily --- /etc/cron.hourly: drwxr-xr-x 2 root root 4096 Jan 10 09:51 /etc/cron.hourly --- /etc/cron.monthly: drwxr-xr-x 2 root root 4096 Jan 10 09:55 /etc/cron.monthly --- /etc/cron.weekly: drwxr-xr-x 2 root root 4096 Jan 10 09:56 /etc/cron.weekly -- System Information: Debian Release: 11.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-10-amd64 (SMP w/4 CPU threads) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages cron depends on: ii adduser 3.118 ii debianutils 4.11.2 ii init-system-helpers 1.60 ii libc6 2.31-13+deb11u2 ii libpam-runtime 1.4.0-9+deb11u1 ii libpam0g 1.4.0-9+deb11u1 ii libselinux1 3.1-3 ii lsb-base 11.1.0 ii sensible-utils 0.0.14 Versions of packages cron recommends: pn default-mta | mail-transport-agent <none> Versions of packages cron suggests: ii anacron 2.3-30 pn checksecurity <none> ii logrotate 3.18.0-2 Versions of packages cron is related to: pn libnss-ldap <none> pn libnss-ldapd <none> pn libpam-ldap <none> pn libpam-mount <none> pn nis <none> pn nscd <none> -- Configuration Files: /etc/crontab changed [not included] -- no debconf information
