similar to: sysctl setting reset

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

It seems that the value of net.ipv4.ip_conntrack_max has no so much to do with the conntrack ''cause the when I measure current number of connections i.e.: wc -l /proc/net/ip_conntrack they show as ~20-30 000 connection, but I set sysctl -w net.ipv4.ip_conntrack_max=150000 and packets get dropped, I have to set it to value above 200 000 so that packets are not dropped ?!! Any idea

Hello, I''ve tried to change ipt_conntrack hashsize and con under my debian charge but doesn''t work ! Ive got 2876Mb available for conntrack so I''ve done (according to some previous mail and this http://www.wallfire.org/misc/netfilter_conntrack_perf.txt) CONNTRACK_MAX = 2876 * 64 = 184064 HASHSIZE = 2876 * 8 = 23002 But the near power of 2 is 2^16 = 131072

Hello I''ve got a server with 3Gb of ram and I want to keep 256 for the system and allocate the rest to conntrack ... I''ve tried to change the HASHSIZE of the ip_conntrack but dmesg return me this error ! ip_conntrack version 2.4 (2097152 buckets, 16777216 max) - 236 bytes per conntrack ip_conntrack: falling back to vmalloc. .... I''ve use this "math"

I dont see any reason this will have anything to do with the issue. In any case, i re-installed the package, had the symlink, moved my definitions to sysctl.conf. still the same....

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

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

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

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

I have a tricky problem. I''m going to use Augeas, like here http://projects.puppetlabs.com/projects/1/wiki/Puppet_Augeas#/etc/sysctl.conf to maintain sysctl.conf. However, since iptables is already disabled, when I add more lines to sysctl.conf with augeas and run sysctl -p, the following lines (which are already there) cause a failure. # Disable netfilter on bridges.
