sysctl.conf ubuntu upgrade to 14.04

  • Posted May 2, 2014

Hi, I just upgraded to 14.04 during which it asked if I wanted to keep the old /etc/sysctl.conf file or accept the maintainers release. I accepted the new one, but I’ve kept a copy of the old. I noticed there are some ‘# Digital Ocean Recommended Settings:’ lines. Is it recommended that I add these back into the new file? (or has DO released a new sysctl.conf file I should copy in?) Thanks in advance, -Duncan.

I just install Ubuntu Server 14.04.3 and my sysctl1.conf is empty, what should I do?

@peter: Keeping the old file should be fine. The DigitalOcean defaults are the same.

i wasn’t sure what to do, so I just kept the old files when prompted. <br>Should I make the recommended changes? <br>What happens if I keep the old file? <br> <br>Thanks

Thanks Andrew.
