Why is someone not setting up an email server conform RFC's and seems to be you have an ipv6.. so set the ptr record. Hai Linda, I do have ipv4 and ipv6 on my server, and im never blocked.. but i did setup conform all rfcs.. i block servers in the same way. so yes, i did set my reverse for ipv4 and ipv6.. what most people do wrong.. 1) the hostname must have A and RR (PTR) and MX

Why would the samba list be looking for a reverse host name via IPV6? IFAIK I only have an IPv4 addr and reverse addr. I don't know if the original went to the person in france or not. Anyone else getting bounces like this? -------- Original Message -------- Subject: Returned mail: see transcript for details Date: Tue, 7 Apr 2015 13:19:19 -0700 From: Mail Delivery Subsystem

I have a server running Centos 5.2 as a Xen host. A problem that's shown up recently is that at boot, the dom0 interface eth0 doesn't come up properly, with the result that the host is only accessible via remote console. If I execute 'service network restart', eth0 comes up normally, with an IP address and the correct routing. Three guests have been created via virt-manager

1: is it possible to use ioemu:sda instead of ioemu:hda ? 2: is ioemu keyword optionnal ? conf seems to work without 3: why d i need to put vfb = [ "type=vnc,vncunused=1,keymap=fr" ] line ? seperate vnc = 1 + vncunused = 1 look identical to me, but are ignored. have the conf parser changed ? 4: during dom0 startup: > * Starting Xen control daemon ... > * Error: either

Has anyone ran into this issue before? 2 physical nics: eth0 hooked up to 10.175.8.0/21 eth1 hooked up to 10.150.8.0/24 Ifconfig -a looks like this: [root@mgixen1 ~]# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:19:B9:F2:1B:C3 inet addr:10.175.8.158 Bcast:10.175.15.255 Mask:255.255.248.0 inet6 addr: fe80::219:b9ff:fef2:1bc3/64 Scope:Link UP

Hi, Can you show as the config of eno4? And can you diff the config of eno1 and eno4. Looks like there is a difference somewhere. Regards, Simon > > > This server is equipped with four nics

Hello, I've been trying to implement a bridge in place for a clustered firewall at one of our office locations. Currently we NAT two class C's internally. We decided, for performance reasons, that it would make sense to put our servers into an official DMZ. So we started this bridging project. Our goal is to have two redundant firewalls in place. There is no need for active/active.

Hi, I've seen that in the past, libvirt couldn't start VMs when the disk image was stored on a file system that doesn't support direct I/O having the 'cache=none' configuration [0]. On the KubeVirt project, we have some storage tests on a particular provider which does just that - try to create / start a VM whose disk is on tmpfs and whose definition features

Hello, I am not able to see vrbr0 in my box. Can some one help me with this ? . I am trying KVM+libvirt and planing to use Routed mode. I hope this virbr0 must be up for using this .

Dear CentOS-Community, we are facing the following issue: A secondary ip address seems to be automatically added to a nic which causes several issues in our setup. This server is equipped with four nics which are currently in use: # nmcli con show NAME????? UUID????????????????????????????????? TYPE????? DEVICE eno2????? cb6fcb54-be52-4ab6-8324-88091a0ea1a0? ethernet? eno2 eno4?????

Hi, I would like to run a network firewall as a VM on a KVM host. There are ~ 25 VLANs delivered to the KVM host on three dedicated links, no LACP or other things. I have the VLANs 100-180 on the host's enp1s0, the VLANs 200-280 on the host's enp2s0 and the VLANs 300-380 on the host's enp3s0. To save myself from configuring all VLANs on the KVM host, I'd like to hand the entire

Hi all, I finally got my IPSec tunnel from my Fedora firewall system (running Shorewall 4.0.6) to a remote Draytek Router up-and-running, but I''m having difficulties directing traffic through the tunnel. From the output of "racoon -F -f racoon.conf" and the connection status page of the Draytek I can tell the tunnel is UP, but ping and traceroute requests to several hosts
