Re: [CentOS] Centos 7.6 & ether-wake
Everyone, I have not been able to get ether-wake to work waking up other centos 7.6 machines after the upgrade to Centos 7.6. Has anyone else had this problem, and if so any luck with a fix? Greg Ennis -- Everyone, I have found the solution to the problem related to wake-on-lan after the upgrade to Centos 7.6 from Centos 7.5 It appears that NetworkManager was changed and now you have to enter the command : nmcli c modify enp2s0 802-3-ethernet.wake-on-lan magic Which adds ETHTOOL_OPTS="wol g" to : /etc/sysconfig/network-scripts/ifcfg-enp2s0 It is interesting in that I found this had to be added only to the motherboard network device, but did not have to be added to network cards in the pcie slots. It also could be fixed by running the command at the time of boot : ethtool -s enp2s0 wol g However this command had to be used with every boot, and always allowed wake-on-lan to work after a soft shutdown, but if you pulled the plug and completely powered the system down it did not work on the first hard reboot. After entering "nmcli c modify enp2s0 802-3-ethernet.wake-on-lan magic" I was able to use wake-on-lan after both soft shutdowns and power out shutdowns.

Then I saw in a later post that you’re using an editor (Geany) without intelligent formatting for Markdown. So that’s my recommendation: switch to a text editor that does intelligent things with Markdown like continuing the list when you hit Enter from within a list item, adding a level to the list when you hit Tab within a list, returning to the prior level with a Shift-Tab, auto-indenting list items when you hit the editor’s wrapping limits, etc. I’m not sure what distinction you’re trying to make by listing “txt” output along with Markdown, so I don’t know what transform to suggest. As for “OO”, I assume that means OpenOffice, in which case what you actually mean is ODF, its file format. And for that, I suggest that you use Pandoc, which will get Markdown into that format and many more: $ pandoc --to odt x.md > x.odt $ pandoc --list-output-formats As for the actual editor, there are several choices. The first one I reached for was VSCodium, which is Microsoft Visual Studio Code with the branding, telemetry and non-FOSS licensed stuff stripped out. (Shades of CentOS vs RHEL…) I’m working with a text-only CentOS VM here and couldn’t get a GUI running on it — a problem I’ll take up in a separate thread — so I’ll just point you at the VSCodium Linux install instructions and hope they work for you there: https://github.com/VSCodium/vscodium/releases Once you’ve got VSCodium running, you’ll need to install the “Markdown All In One” plugin. (Ctrl-Shift-P, install, search for Markdown, select first option [currently] listed.) That will do as described above: auto-number, auto-indent, Tab/Shift-Tab to change indent level, etc. The availability of such plugins is a large part of the reason Code is taking over so much of the programmer’s text editor world. Give it a try. If VSCodium doesn’t work on CentOS, you could try Visual Studio Code, the original project, which probably has better packaging: https://code.visualstudio.com/docs/setup/linux I used that for probably a few years before VSCodium came along. Don’t be scared by the branding: it shares almost nothing with Visual Studio other than branding and a parent organization. If you really want a CLI-only experience, I got a suitable setup working with Vim and the Bullets plugin: https://github.com/dkarter/bullets.vim Instead of Tab and Shift-Tab to change indent levels it uses Ctrl-T and Ctrl-D, which I find odd, but that’s the sort of affordance you have to give up on when you’re working in an ANSI terminal. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Org-mode fits the bill. Emacs org-mode seems to get positive reviews, and it has been ported to vim too (many alternative plugins, but probably with less features than the original emacs version). https://en.wikipedia.org/wiki/Org-mode Org 9.2 was released in December 2018, so the development seems not to be dead.

If you don't have any usage monitoring turned on, then after the fact the answer is no. A simple approach is to run top in batch mode (see the top man page) from a cron job that you run at whatever frequency you want to capture data for. Log that, and say vmstat output - perhaps sending an alert when the vmstat load is above some threshold. This is all fairly lightweight and easy to set up. There are other packages that can get more detail, but take some learning and setup time. Remember that things like logrotate, logwatch etc., tend to run in the ~3am timeframe (depending on your configuration). These can generate fairly high spot load if your logs are large. - Richard [please only reply to the list.] ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] Resource utilisation of processes on linux server.
Hi, I have around 6 processes running on CentOS Linux release 7.6.1810 (Core). Is there a way to find out which process is taking resources like memory, CPU, I/O and network. Process 1 : How much memory, CPU, I/O and network is currently consuming on linux server Process 2 : How much memory, CPU, I/O and network is currently consuming on linux server Process 3 : How much memory, CPU, I/O and network is currently consuming on linux server and so on and so forth.
