Re: Cannot successfully connect Ethernet interface to bridge with NMCLI

OK, so that did it. I didn't want to mess around under the hood by deleting the device itself, but deleting the connection and then creating a new one connected to the existing Ethernet interface device allowed me the create a bridge-slave that successfully came up and made the machine IP accessible...

Re: Cannot successfully connect Ethernet interface to bridge with NMCLI

Ah, back to basics. Always a helpful troubleshooting approach. :) Here are the con and dev outputs with all fields in pretty format. This is the "working" configuration with the manual interventions I don't particularly care for. ====================================== NetworkManager connection profi...

Cannot successfully connect Ethernet interface to bridge with NMCLI

I’m attempting to move the IP from an Ethernet interface to a bridge. From what I’ve found, the commonly recommended process for this is to remove the IP from the Ethernet interface, create a bridge with the IP and attach the Ethernet interface to that bridge. So, I log into the console, use nmtui t...

Re: Libvirt virtual network vs linux host bridge

Yeah, that was the crux of the decision I'm facing. Seeing as RH is pushing NetworkManager over the classic network service I'm just gonna go with the flow and use NetworkManager for everything. It'll make the transition to 8 smoother, when the time comes. Again, thanks very much for your feedback. ...

Re: Libvirt virtual network vs linux host bridge

Thanks so much for your response! I was worried that libvirt created virtual networks were some sort of bloated userland monstrosity, but I see what you're saying about them really being OS bridges under the hood with some advanced services I don't need in this context. So I think I'll build the bri...

Libvirt virtual network vs linux host bridge

Greetings, Gurus! :) Looking to see what the hive mind’s experience is choosing between using virsh to create virtual networks to attach KVMs to vs building bridges in CentOS and then connecting the VM interfaces to those bridges. Not doing anything particularly fancy, so feature set isn’t a high pr...

Best SNMP-based Nagios plugins to monitor CentOS 7 servers

Dear CentOS gurus, I’m implementing Nagios Core for monitoring and I’m looking to do host health monitoring via SNMP (decided against loading NRPE on all my servers). I see that check_snmp comes with the default install but rather than dig out the OIDs I need and write the code to do all the thresho...

Updating a SO library from source that was originally installed by a package manager

Dear CentOS Gurus, OK, so the situation is that I need to update gpgme on my CentOS 7 minimal install to 1.4.3 or higher (project is currently at 1.13). If you’re curious why, see here: https://community.greenbone.net/t/problem-building-gpgmeutils-c-o-in-gvm-lib-10-0-2-on-centos-7-minimal/5854/3 The...

Re: grepping stacks of gzip file - zgrep?

zgrep is a standard utility installed as part of CentOS - it's part of the gzip package. I swear the first thing I did when I heard about zgrep was try to use it and I got a "command not found" back. Checked again when you said it was installed by default and there it is! Must have fat fingered it ...

grepping stacks of gzip file - zgrep?

Greeting, Gurus! :) I need to grep a stack of files in a directory tree but the files are gzip'ed so I'm looking for recommendation on how to do that. Unzipping, grepping and rezipping afterwards in a script sounds like a huge PITA... I found mentions of zgrep online, but I can't see it (or the zuti...
