NAMEsysctl.conf − sysctl preload/configuration file

---

DESCRIPTIONsysctl.conf is a simple file containing sysctl values to be read in and set by sysctl. The syntax is simply as follows: # comment ; comment token = valueNote that blank lines are ignored, and whitespace before and after a token or value is ignored, although a value can contain whitespace within. Lines which begin with a # or ; are considered comments and ignored. If a line begins with a single −, any attempts to set the value that fail will be ignored.

---

NOTESAs the /etc/sysctl.conf file is used to override default kernel parameter values, only a small number of parameters is predefined in the file. Use /sbin/sysctl −a or follow sysctl(8) to list all possible parameters. The description of individual parameters can be found in the kernel documentation.

---

EXAMPLE# sysctl.conf sample # kernel.domainname = example.com ; this one has a space which will be written to the sysctl! kernel.modprobe = /sbin/mod probe
