similar to: Disabling IPv6 with NetworkManager

Hello, Why is it so, that NetworkManager allows, and in several cases I've had, defaults to setting default route to several interfaces at the same time? Had my fair share of problems with how 172.17.62.something interface tries to ask for a DHCP lease from 193.something network. I know I could set never-default to the interfaces, but I shouldn't have to do it to every machine I had.

Hello, Today a virtual server under my administration ran out of disk space, so I had to get extra space to it.. while it was running, because it's an important web server without any kind of HA/Load Balancing (don't do that, kids). So what happened, is that after another administrator had extended the disk from VMWare, I tried to extend it from the OS side. Everything went well,

I did not do pvresize because neither "pvs" or "pvdisplay" reported to have free space. After reboot they did, after which doing pvresize worked successfully.

Hi, Is there some tool or method in centos that can limit cpu usage to some percentage for specified processes that consume large cpu resource? I found cpulimit which is only able to limit one process. what I want is one tool that can limit several same processes' cpu usage. Thanks! Regards andrew

Used steps on sysctl from?Centos7 FAQ (https://wiki.centos.org/FAQ/CentOS7)?and some gathered on internet # cat /etc/sysctl.d/90-disable_ipv6.conf? net.ipv6.conf.all.disable_ipv6=1 net.ipv6.conf.default.disable_ipv6=1 net.ipv6.conf.eth0.disable_ipv6=1 net.ipv6.conf.eth1.disable_ipv6=1 net.ipv6.conf.all.use_tempaddr=0 net.ipv6.conf.all.autoconf=0 net.ipv6.conf.all.accept_ra=0

you can disable ipv6 at a machine level echo net.ipv6.conf.all.disable_ipv6=1 > /etc/sysctl.d/disableipv6.conf which I did. <quote> So. Installed my first Samba 4.03 PDC Kept it simple, used samba's internal DNS forwarding to the main DNS server. Edited resolv.conf to query localhost. All was well until I tried to pull down ntp from my debian (6.0) apt source. Suddenly, no can

I can boot from DVD. I deleted kernel. Thought it will fix the problem. Now I can see rescue menu only. Kernel source is there. How to get back kernel.

Hi all, I'm pretty new to CentOS. I am working with a newly set-up server: [cbearden at host ~]$ lsb_release -a LSB Version: :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: CentOS Description: CentOS release 6.3 (Final) Release: 6.3 Codename: Final I'm trying to solve this problem (X11 forwarding)

I have updated to 5.6 - GREAT job guys... when I do "host slashdot.org" for example it comes back immediately. when I enter slashdot.org on firefox it says "Looking up slashdot.org" for a LONG time like 15 or 20 seconds before continuing. I have set network.dns.disableIPv6 true. Any idea why firefox is so slow? Jerry

I do not working with ipv6, I have disable, but I have the same error, I can read in internet that this ipv6 ip 2001:638:603:d06e::80:230: belong to url samba.org.... If I try to connect to this url using some navegator I connected perfect....but when I run git pull using command line I can not connect.. > Am 28.02.2015 um 15:37 schrieb sandy.napoles at eccmg.cupet.cu: >> Hello list,

I have just moved a host from a network that supports static IPv4 and IPv6. The IPv4 addr is set in ifcfg-eth0, and the IPv6 via RA (I set the MAC so I get an IPv6 addr that I like). I just moved the host to a network that supports static IPv4, but only dymanic IPv6, so at this time (until I get static IPv6), I need to disable the global IPv6 addressing. So in the ifcfg-eth0 file I set:

CentOS 7.5, and on one system, I'm getting: setroubleshoot: SELinux is preventing /usr/sbin/sendmail.sendmail from read access on the file disable_ipv6 ll -Z shows -rw-r--r--. root root system_u:object_r:sysctl_net_t:s0 /proc/sys/net/ipv6/conf/all/disable_ipv6 I find this peculiar. Anyone have a resolution, or is this a bug? mark
