安装后msktutil
,cron 每天都会抱怨,并且我会收到包含以下内容的电子邮件:
run-parts: /etc/cron.daily/msktutil exited with return code 1
当我跑步时:
user@box:~$ sudo /etc/cron.daily/msktutil
user@box:~$ echo $?
0
另外,如果我修改 msktutil 以在详细模式下运行,则不会暴露任何内容(它告诉我更改 keytab 内容还为时过早)。
我错过了哪些重要的测试来查明(真正痛苦的)问题?
/etc/crontab 文件是:
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
# m h dom mon dow user command
17 * * * * root cd / && run-parts --report /etc/cron.hourly

msktutil 是一个 sh 脚本:
cat /etc/cron.daily/msktutil
#!/bin/sh
test -x /usr/sbin/msktutil || exit 0
# These options are overridden in /etc/default/msktutil.
# Edit there, not here.
AUTOUPDATE_ENABLED="false"
AUTOUPDATE_OPTIONS=""
[ -r /etc/default/msktutil ] && . /etc/default/msktutil
[ "$AUTOUPDATE_ENABLED" = "true" ] || exit 0
exec /usr/sbin/msktutil --auto-update $AUTOUPDATE_OPTIONS
