NTP<\/strong>\u00a0is used for ensuring the time on your\u00a0dedicated server<\/span><\/a><\/strong>\u00a0is accurate. Some configurations of this software cause it to be vulnerable to being abused to conduct\u00a0DDoS attacks<\/strong>. We suggest fixing the server’s configuration so it can no longer be abused.<\/p>\n

To prevent abuse:<\/p>\n

\n
1. Open your\u00a0ntp.conf<\/strong>\u00a0file\u00a0(generally in \/etc\/ntp.conf)<\/strong><\/li>\n
2. Remove any existing lines that begin with\u00a0‘restrict’<\/strong><\/li>\n
3. Add the following four lines to the beginning of the file:<\/li>\n
4. restrict default kod limited nomodify notrap nopeer noquery<\/li>\n
5. restrict\u00a0-6 default<\/strong>\u00a0kod limited nomodify notrap nopeer noquery<\/li>\n
6. restrict\u00a0127.0.0.1<\/strong><\/li>\n
7. restrict\u00a0-6 ::1<\/strong><\/li>\n
8. Restart your NTP server with\u00a0‘service ntpd restart’<\/strong>\u00a0or\u00a0‘service ntp restart’<\/strong><\/li>\n<\/ol>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"open","ping_status":"closed","template":"","format":"standard","manualknowledgebasecat":[229],"manual_kb_tag":[264],"_links":{"self":[{"href":"https:\/\/support.aklwebhost.com\/wp-json\/wp\/v2\/manual_kb\/2372"}],"collection":[{"href":"https:\/\/support.aklwebhost.com\/wp-json\/wp\/v2\/manual_kb"}],"about":[{"href":"https:\/\/support.aklwebhost.com\/wp-json\/wp\/v2\/types\/manual_kb"}],"author":[{"embeddable":true,"href":"https:\/\/support.aklwebhost.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/support.aklwebhost.com\/wp-json\/wp\/v2\/comments?post=2372"}],"version-history":[{"count":1,"href":"https:\/\/support.aklwebhost.com\/wp-json\/wp\/v2\/manual_kb\/2372\/revisions"}],"predecessor-version":[{"id":2373,"href":"https:\/\/support.aklwebhost.com\/wp-json\/wp\/v2\/manual_kb\/2372\/revisions\/2373"}],"wp:attachment":[{"href":"https:\/\/support.aklwebhost.com\/wp-json\/wp\/v2\/media?parent=2372"}],"wp:term":[{"taxonomy":"manualknowledgebasecat","embeddable":true,"href":"https:\/\/support.aklwebhost.com\/wp-json\/wp\/v2\/manualknowledgebasecat?post=2372"},{"taxonomy":"manual_kb_tag","embeddable":true,"href":"https:\/\/support.aklwebhost.com\/wp-json\/wp\/v2\/manual_kb_tag?post=2372"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
