Rex::Commands::Sysctl - Manipulate sysctl
With this module you can set and get sysctl parameters.
Version <= 1.0: All these functions will not be reported.
All these functions are not idempotent.
use Rex::Commands::Sysctl; my $data = sysctl "net.ipv4.tcp_keepalive_time"; sysctl "net.ipv4.tcp_keepalive_time" => 1800;
This function will read the sysctl key $key.
If $val is given, then this function will set the sysctl key $key.
task "tune", "server01", sub { if( sysctl("net.ipv4.ip_forward") == 0 ) { sysctl "net.ipv4.ip_forward" => 1; } };
If both $val and ensure option are used, the sysctl key is modified and the value may persist in /etc/sysctl.conf depending if ensure option is "present" or "absent".
With ensure => "present", if the key already exists in the file, it will be updated to the new value.
task "forwarding", "server01", sub { sysctl "net.ipv4.ip_forward" => 1, ensure => "present"; }
