How to configure DNS server in RHEL 7 / CentOS 7
by Joe Smithian 05 Apr '16

05 Apr '16

How to configure DNS server and search domain common for all network interfaces not per device? The only reliable way I found we can set DNS name server and search domain in CentOS 7 is using nmcli which adds DNS name server and search domain to *a specific interface*, e.g. nmcli con mod eth0 +ipv4.dns [IP_ADDRESS]. But I want to set them for all interfaces weather they are configure and connected or not. How can we do that? More back ground information: I am using NetworkManager and nmcli tool to configure multiple wired Ethernet interfaces on CentOS 7. I want to set common DNS name server and search domain for all interfaces. /etc/resolv.conf is generated by NetworkManger and we cannot manually modify it. Thanks, Joe

Disabling network service in CentOS 7
by Joe Smithian 05 Apr '16

05 Apr '16

Hi all, I've recently started using NetworkManger service and nmcli tool, I like it much better than the old network service and manually modifying network scripts. I've seen many online questions on how to disable NetworkManger but I have the opposite question! I am wondering if it be OK to disable network service altogether and just use NetworkManger for configuring and managing Ethernet interfaces. I care about wired Ethernet interfaces only. I disabled network service and rebooted my machine without any networking problem but I wanted to conform that that would be OK.

VPN suggestions centos 6, 7
by david 05 Apr '16

05 Apr '16

Folks I would like to have my windows 7 laptop communicate with my home server via a VPN, in such a way that it appears to be "inside" my home network. It should not only let me appear to be at home for any external query, but also let me access my computers inside my home. I already have this working using M$'s PPTP using my home Centos 6 gateway/router as the PoPToP server. However, I am concerned about the privacy/security of such a connection. I have seen discussions of OpenVPN, OpenSwan, LibreVPN, StrongSwan (and probably others I haven't noted). I'd be interested in hearing from anyone who wishes to comment about which to use, with the following requirements: 1) As noted, it should be secure (anti NSA?) 2) Works on Centos 6 and Centos 7 and Windows 7 (and for the future, Windows 10) 3) Can be set up on the server with command line interfaces only (no GUI) And, should not be a nightmare to set up. Any thoughts? David

virt-manager virtual USB disk unavailable option
by Roberto Cantalapiedra 05 Apr '16

05 Apr '16

Hi, I have installed virt-manager 1.3.2 and I want to create a virtual USB disk (not USB host passthrough) but unfortunately I don't see that option when I try to add a new storage hardware. I have another PC with virt-manager 0.9.5 and Linux Mint and I have that option and it is working perfectly. My CentOS version is: 7.2.1511 Thanks in advance <https://www.google.com/search?q=host+passthrough+usb&spell=1&sa=X&ved=0ahUK…>

You can convert to local time with $(date -d '2016-04-06 7:00 UTC') The expected "downtime" is estimated to ~30 minutes , time needed to update/propagate updated dns A/AAAA record[s] + last mysql dump/restore on the new node.

EPEL - Clamav update?
by Rob Kampen 04 Apr '16

04 Apr '16

EPEL maintainers? I note messages in the log about updated version 0.99.1 of CLAMAV being available since Mar 5th. for CentOS 6 no update is available yet. I used to use rpmforge for this package but that languished for months before updates became available and eventually stopped altogether. Is there something I can do to assist in getting this package updated? I have no idea if this is a difficult package to compile with lots of dependancies or some otherwise complexities. In this era of constant SPAM and so many virus / trojan attempts to do harm to others, it is vital that we run this package to protect our users. Please let me know if / how I can assist. Kind regards Rob

In general I think it is most important to keep your signatures current. I don't get the sense that the changes between [sub-]point-releases are earth shattering (despite the ominous warning that you will see in your logs).
