I understand that the contents of /etc/sysctl.conf should be read and executed at system startup. However that never happens and I have to run sysctl -p after every reboot to get the settings I want. This is happening on every CentOS machine and VM I have. I can see in the startup scripts that "sysctl -e -p /etc/sysctl.conf >/dev/null 2>&1" is run at start up by the

Hello, I tried to get my sound working, and long story short: rc.d/sysctl parses sysctl.conf wrongly if there are sysctls of the form mib=val1=val2 which is what you need for sound. For reference I needed/wanted dev.hdaa.4.nid25_config=as=1,seq=15 dev.hdaa.4.nid31_config=as=1 I believe the following patch would address the incorrect parsing: --- /etc/rc.d/sysctl.old 2013-02-27 22:00:00.000000000 +0100 +++...

Hey all, After upgrading to CentOS 7.2, non of my servers run systemd-sysctl on boot. So far, I tried running manually /usr/lib/systemd/systemd-sysctl, it runs smoothly and updates all the parameters. I also ran sysctl --system, which also executes successfully. I checked within systemd, and systemd-sysctl is wanted by the sysinit.target which is wanted by the multi-user.target - the one I boot

Hi all, It appears as though SVN r244198 introduced a regression. One that is affecting HEAD and stable/10 (for upcoming 10.0-R) and was introduced 10 months ago (but does not appear to have made it into 9.x yet or even stable/9). The regression introduced by r244198 is that: Whilst "sysctl -f /etc/sysctl.conf" will parse parameters with quoted values... "service sysctl

Is the file labeled properly? Anything in audit.log?

Hi, If I disable ipv6 via the kernel command line, ipv6.disable=1, then systemd-networkd fails to bring up any interfaces. Removing the option and networking works as expected. Phil.

If I execute these via command line, will they persist after a reboot? Or, should I be putting these into a file like /etc/sysctl.conf? --------------snip-------------- /sbin/sysctl -w net.ipv4.tcp_max_syn_backlog=2048 /sbin/sysctl -w net.ipv4.tcp_fin_timeout=30 /sbin/sysctl -w net.ipv4.tcp_keepalive_intvl=10 /sbin/sysctl -w net.ipv4.tcp_keepalive_probes=7 /sbin/sysctl -w

The network-bridge script fails when setting a few sysctls which are only available if ebtables is present in the host kernel. Fix by ignoring the return value of the sysctl command.

You are correct, I'll refine my problem, By running "systemctl status systemd-sysctl" I also receive the same output, but a simple "cat /proc/sys/vm/swappiness" returns the default value, and not the one set by my conf file. But, if I run "/usr/lib/systemd/systemd-sysctl" the "cat /proc/sys/vm/swappiness" does return the correct value. Any idea ? Does

Hi all. i'm trying to modify some parameters but when system reboots it doesn't load. For the sysctl if I run sysctl -p then it changes /etc/sysctl.conf net.ipv4.netfilter.ip_conntrack_max = 1048576 /etc/modprobe.conf options ip_conntrack hashsize=131072 after reboot results cat /proc/sys/net/ipv4/netfilter/ip_conntrack_max 65536 cat

Hello, i use a file type to manage sysctl.conf. For some work i override this file by doign File[''/etc/sysctl.conf''] and i have an exec refresh only to run sysctl -p so it reread the sysctl.conf file if changed. My issue is that at each run i got, i start in state when i see the overriden one on the server: 1st run, i have the basic sysctl.conf not the ovveriden one

Please: file a bug report and attach the patches to it. Else they are pretty much guaranteed to wind up at /dev/null, because nobody tracks patches on the list AFAIK.

Hello everyone... :) I liked the idea of having descriptions for various sysctl oid's in -CURRENT, so I have created a patch to merge these over to -STABLE. I am unsure as to how much work has already gone into bringing this to -STABLE, but as the descriptions already exist in the source, I am fairly confident that it was planned at some point. All I can really ask is that someone with more
