Warning چیست




Image result for ‫Warning چیست‬‎


بعد از اتمام آنالیز سازه فولادی واقدام به طراحی از طریق start design به این warningبرخورد می کنم.وقتی چندین بار yes را انتخاب می کنم باز از بین نمی رود فقط گاهی تعداد مقطه ناهماهنگ را کمتر یا مساوی حالت قبل نشان می دهد.
ولی وقتی no را چند بار پشت سر هم می زنم بلاخره نتیجه طراحی را نشان می دهد 


ر بخش چک کردن امنیت سرور چندین وارنیگ دارم که یکی یکی برای راهنمایی دوستان باتجربه قرار می دهم 
ممنون می شوم که دلیل و راه حل رفع آن را اعلام کنند .

ممنون 

خطاها شامل :

کد:
 Check /tmp is mounted as a filesystem :    WARNING        /tmp should be mounted as a separate filesystem with the noexec,nosuid options set

کد:
  Check /etc/cron.daily/logrotate for /tmp noexec workaround :   WARNING      Due  to a bug in logrotate if /tmp is mounted with the noexec option, you  need to have logrotate use a different temporary directory. If you don't  do this syslog may not restart correctly and will write to the wrong  (older) log files. See here for a way to do this

کد:
  Check /var/tmp is mounted as a filesystem  :  WARNING     /var/tmp should either be symlinked to /tmp or mounted as a filesystem
