HI folks. I am developing a protocol and I need to bind to an IP address that is not configured to my machine. The problem is with bind(). The sysctl system call seamed to overcome the problem of bind if you set the proc/sys/net/ipv4/ip_nonlocal_bind flag. Although I tryed to set the flag either... (7 Replies)

systemd-sysctl.service
SYSTEMD-SYSCTL.SERVICE(8) systemd-sysctl.service SYSTEMD-SYSCTL.SERVICE(8)NAME
systemd-sysctl.service, systemd-sysctl - Configure kernel parameters at boot
SYNOPSIS
/lib/systemd/systemd-sysctl [OPTIONS...] [CONFIGFILE...]
systemd-sysctl.service
DESCRIPTION
systemd-sysctl.service is an early boot service that configures sysctl(8) kernel parameters by invoking /lib/systemd/systemd-sysctl.
When invoked with no arguments, /lib/systemd/systemd-sysctl applies all directives from configuration files listed in sysctl.d(5). If one
or more filenames are passed on the command line, only the directives in these files are applied.
In addition, --prefix= option may be used to limit which sysctl settings are applied.
See sysctl.d(5) for information about the configuration of sysctl settings. After sysctl configuration is changed on disk, it must be
written to the files in /proc/sys before it takes effect. It is possible to update specific settings, or simply to reload all
configuration, see Examples below.
OPTIONS --prefix=
Only apply rules with the specified prefix.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
EXAMPLES
Example 1. Reset all sysctl settings
systemctl restart systemd-sysctl
Example 2. View coredump handler configuration
# sysctl kernel.core_pattern
kernel.core_pattern = |/libexec/abrt-hook-ccpp %s %c %p %u %g %t %P %I
Example 3. Update coredump handler configuration
# /lib/systemd/systemd-sysctl --prefix kernel.core_pattern
This searches all the directories listed in sysctl.d(5) for configuration files and writes /proc/sys/kernel/core_pattern.
Example 4. Update coredump handler configuration according to a specific file
# /lib/systemd/systemd-sysctl 50-coredump.conf
This applies all the settings found in 50-coredump.conf. Either /etc/sysctl.d/50-coredump.conf, or /run/sysctl.d/50-coredump.conf, or
/usr/lib/sysctl.d/50-coredump.conf will be used, in the order of preference.
See sysctl(8) for various ways to directly apply sysctl settings.
