[NOAAPORT #GGP-872890]: New Noaaport server with ldm



Hi Heather,

OK.

re:

Good for you!  Kids _should_ play in snow!!

re:

OK.

re:

> my old build.

I did a Google (tm) search for CentOS 7 and sysctl.conf, and I found:

  "RHEL 7 has a service named “tuned” which helps to create custom profiles
  and it overrides the “sysctl” values set in the /etc/sysctl.conf file,
  because “tuned” service will start after “sysctl” service."

This suggests that there could be a profile in place that is overriding
the settings that you put in your /etc/sysctl.conf file, and this, in
turn, might be (one of the reasons) why things are not working... yet.

The URL for the page I'm looking at is:

https://www.thegeekdiary.com/centos-rhel-7-sysctl-kernel-parameter-doesnt-take-effect-after-reboot/

Near the top of the article is:

  1. Check the active tune profile in the affected server.

  tuned-adm active
  Current active profile: virtual-guest

  Presumably, 'tuned-adm active' will need to be run as 'root'.

If there is an active profile, then we can see if it is setting
net.ipv4.conf.default.rp_filter, and if it is, if the setting is
what is preventing the values that you have put in /etc/sysctl.conf.

This may (or may not) be due to a tuned profile being in place.

OK.

This looks OK as the Uncorrectable rate is zero.

Let's start with you doing some investigation of tuned, and then
go from there.

I am in the office until about 4:15 MST.

Cheers,
