/usr/bin/vddos-autoswitch automatically identifies overloaded websites (if the website can not respond 200 HTTP Status after 2 seconds - it mean they are too slow or high load...) And after that vddos-autoswitch will changes their Security Mode in /vddos/conf.d/website.conf:
WARNING: Please remove [...] in all the below commands!
Auto check/switch security mode for a domain (already in the website.conf file) to 5s mode (if it is being slow/high load):
/usr/bin/vddos-autoswitch [checkdomain] your-domain.com 5s
Auto check/switch security mode for each all domains (already in the website.conf file) to 5s mode (if it is being slow/high load):
/usr/bin/vddos-autoswitch [checkalldomain] 5s
Auto check/switch security mode for each domain in the list domains to 5s mode (if it is being slow/high load):
/usr/bin/vddos-autoswitch [checklist] /etc/listdomains.txt 5s
Flush all security mode for all domain (already in the website.conf file) if they are not slow/high load:
/usr/bin/vddos-autoswitch [flushalldomain] /etc/listdomains.txt no
If you want to automate the inspection and changes website's Security Mode. You can configure vDDoS Auto Switch to crontab as follows:
For example, check the status of every website every 3 minutes and automatically flush all security mode for them (if their security mode have been switch) every 30 minutes:
echo '*/3 * * * * root /usr/bin/vddos-autoswitch checkalldomain high' >> /etc/crontab
echo '*/30 * * * * root /usr/bin/vddos-autoswitch flushalldomain /vddos/conf.d/website.conf no' >> /etc/crontab
echo '* * * * * root /usr/bin/vddos-sensor' >> /etc/crontab
Or you have a list of special domains that need to check the status of every website every 3 minutes and automatically flush all security mode for them every 30 minutes:
echo '*/3 * * * * root /usr/bin/vddos-autoswitch checklist /etc/listspecialdomains.txt captcha' >> /etc/crontab
echo '*/30 * * * * root /usr/bin/vddos-autoswitch flushalldomain /etc/listspecialdomains.txt no' >> /etc/crontab
