Hi all, To do some tests, I have installed a new CentOS7 host (fully patched) using qemu-kvm-ev-2.3.0-31.el7.16.1 instead of qemu-kvm's default package. And I have problems with network inside my guests. All guests can ping to CentOS host but nothing more: can't resolv dns names, can access via tcp to other hosts, etc ... Using same config on other CentOS7 host, but using default

Are the testing kernels (kernel-4.9.37-29.el7 and kernel-4.9.37-29.el6, with the one config file change) working for everyone: (turn off: CONFIG_IO_STRICT_DEVMEM) If we don't hear any negative comments by Wednesday July 19th, 2017 then we are going to push those to updates as they solve iscsi issues with some hardware and don't seem to impact anything else based on limited testing. BTW

Nop. Problem was with systemd-networkd. Using openvswitch of ifcfg-XXX config files, all works ok without problems.

I have been killing myself on this issue over the last 2 weeks. I have setup pam AD authentication using winbind on our companies email servers. That part is currently working. I have been trying to add an existing "Trusted" child domain and allow authentication from that domain as well. I am part of the way there, but not quite to the functional point as of yet. Our primary domain

Hi: The openssh suite of commands have an option to specify address (e.g, ListenAddress for sshd) but I do not see support for bind-to-interface. The motivating use case for me is using openssh commands (sshd, ssh, scp, sftp) with the recent VRF capability added to the Linux kernel. The VRF design relies on the bind-to-interface option to select the correct routing tables. Before I started

Hey guys, I have a question regarding shorewall and vrf functionality. I have shorewall 3.4.8 and kernel 2.6.24-gentoo-r8 I have tried to use iproute2 (ip route and ip rule) to establish multiple routing tables. The biggest problem seems to be, that I cannot add interfaces such as vlan interfaces to the routing table. My target is that linux takes attention of on which vlan interface

To take advantage of the filters, is it as simple as adding these couple of lines in a guest's xml file like the example from https://libvirt.org/formatnwfilter.html#nwfconcepts ? <devices> <interface type='bridge'> <mac address='00:16:3e:5d:c7:9e'/> <filterref filter='clean-traffic'> <parameter name='IP'

Hello, One quick question. Does anyone has experience implementing unified messaging (UM) using Asterisk. Does Asterisk has support for UM ?
