Description the sysctl?

Is there a complete description of the parameters sysctl online?

Google displays only articles with descriptions of some parameters.


PS There are recommendations for changing parameters. Before applying I would like to find a detailed description and to grasp the essence.

OS — RHEL6


Thank you

it is very different everywhere
easier IMHO
sysctl -a|grep primernosti

priority should be to set the task, what needs to change
not "to this change...."

Then easier to search in Google for a given parameter and not all parameters in General. - Waldo_Anderso commented on October 8th 19 at 02:46

In man 5 proc has a description of at least some (see files beginning with /proc/sys/). There in the descriptions there are references to other man pages.

In the manual sysctl (at least in lamp Debian) it is written:

> sysctl is used to modify kernel parameters at runtime. The parameters available are those listed under /proc/sys/
> Procfs is required for sysctl support in Linux.

That is, the key sysctl in Linux correspond to files in /proc/sys (which, incidentally, pleases me). The FreeBSD sysctl to work is used the same system call. Thus the list of keys in linux you can see, making find /proc/sys -type f (or not? please correct if wrong)

And then look at man proc, there is a (scanty) description of some parameters. You can see for example here: tldp.org/LDP/Linux-Filesystem-Hierarchy/html/proc.html

Other parameters that are in /proc/sys, but there is no documentation, the easiest way is probably to Google.
And, even in the manual it was mentioned that pedroletti you can search in /usr/src/linux/Documentation, but I don't know where these files are to find online. - Hanna62 commented on October 8th 19 at 02:47
