dan_nanniNTP (Network Time Protocol) keeps clocks in sync across computer systems by correcting time differences based on a structured hierarchy of time servers. It accounts for network delays and variability to ensure precise and reliable timekeepingHere is how NTP clock synchronization works 😎👇 <a href="https://mastodon.social/tags/devops" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#devops</a> <a href="https://mastodon.social/tags/sysadmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sysadmin</a>Find high-res pdf books with all my <a href="https://mastodon.social/tags/networking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#networking</a> related infographics at <a href="https://study-notes.org" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://study-notes.org</a>

Jeff StandenWe had a self-hosted client copy their MariaDB/InnoDB .ibd table files to a new server and then delete the old one -- _without_ also copying the `ibdata1` system tablespace. No SQL backups. Lots of "Table doesn't exist in engine" errors.Fortunately, the system tablespace could be rebuilt by creating the empty table schemas, using `discard tablespace`, dropping secondary keys, moving .ibd in, `import tablespace`, and adding keys back.Always use SQL backups!<a href="https://phpc.social/tags/mysql" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mysql</a> <a href="https://phpc.social/tags/sysadmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sysadmin</a>

dan_nanniJust like anything else, even widely used Linux tools can become outdated as better and more efficient options emerge.Once deprecated, these tools typically stop receiving new features or security updates, even if they’re still accessible.Here are examples of deprecated Linux commands 😎👇 <a href="https://mastodon.social/tags/opensource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensource</a> <a href="https://mastodon.social/tags/sysadmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sysadmin</a> Find pdf books with all my <a href="https://mastodon.social/tags/linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linux</a> related infographics at <a href="https://study-notes.org" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://study-notes.org</a>

AJ SadauskasSome bad news. Something's gone horribly awry with my <a href="https://gts.sadauskas.id.au/tags/yunohost" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#YunoHost</a> deployment. Any help with this would be greatly appreciated! This is a two-part issue. First, the smaller of the two issues: Phanpy has gone AWOL. It's visible in some places, but not others. Phany is listed as an app on the front page of the YunoHost UI. But go into Admin, and it's not listed as an installed app. Go to the URL it was installed at, and it's just a blank screen. And yet. When I SSH in, and see what's in the /etc/yunohost/apps folder, Phanpy's files are still clearly installed on the server. Now, here's where the Phanpy situation is a big issue...
