hey all,
I tried disabling tcp v6 on a C7 box this way:
[root@puppet:~] #cat /etc/sysctl.conf # System default settings live in /usr/lib/sysctl.d/00-system.conf. # To override those settings, enter new settings here, or in an /etc/sysctl.d/<name>.conf file # # For more information, see sysctl.conf(5) and sysctl.d(5). net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1
Then going:
[root@puppet:~] #sysctl -p net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1
Then I restarted xinetd for good measure:
[root@puppet:~] #systemctl restart xinetd [root@puppet:~] #
Because I'm trying to hit nrpe on this host.
Yet, xinetd/nrpe still seems to be listeing on TCP v6!!
[root@puppet:~] #netstat -tulpn | grep -i listen | grep xinetd tcp6 0 0 :::5666 :::* LISTEN 2915/xinetd
This is a CentOS 7.1 box:
[root@puppet:~] #cat /etc/redhat-release CentOS Linux release 7.1.1503 (Core)
What am I doing wrong? I need to be able to disable tcpv6 completely!
Thanks Tim
