unusual networking question - have DHCP assign the same IP to a computer, regardless of which ethernet port is used
by Tim 31 Jan '18

31 Jan '18

Hi, I have what's probably an odd-ball desire: I have a PC with a 100 Mb/s motherboard ethernet interface, and a 1 Gb/s PCI card ethernet interface. And IPs are assigned from a Fedora PC running a DHCP server which reconfigures its DNS server, on the fly. I'd like the PC to always get assigned the same IP, and hostname, regardless of which ethernet port the (single) ethernet cable would get plugged in to. I'd like the addressing to be consistent, and just work. Having the PC change addresses because the cable got plugged into a different port breaks other things on the network. This is the stanza for this PC in the dhcpd.conf file: host oddbox { # hardware ethernet 00:24:21:9A:6F:6C; hardware ethernet C8:3A:35:DC:54:59; fixed-address 192.168.1.12; option host-name "oddbox"; } It won't allow me to specify two macs, hence one being hashed out. Is this sort of thing do-able? (And controlled from the DHCP server, not manually on the PC in question.) Yes, I know there'd be a world of pain if someone tried to connect both ports at the same time. But there's only one ethernet cable, so that can't happen. And I really don't want to physically block the slower motherboard ethernet port, to prevent it being used accidentally. -- [tim@localhost ~]$ uname -rsvp Linux 4.14.14-200.fc26.x86_64 #1 SMP Fri Jan 19 13:27:06 UTC 2018 x86_64 Boilerplate: All mail to my mailbox is automatically deleted.

Who has created a directory called "~/updates"
by Joachim Backes 31 Jan '18

31 Jan '18

I'm running F27, and found coincidentally a directory called ~/updates containing megs of RPMs in my home directory. Does anybody know wherefrom these entries are coming? Kind regards Joachim Backes Fedora release 27 (Twenty Seven) Kernel-4.14.15-301.fc27.x86_64 Joachim Backes <joachim.backes(a)rhrk.uni-kl.de> https://www-user.rhrk.uni-kl.de/~backes/

Catch22 installing RPM-GPG-KEY
by Jonathan Ryshpan 31 Jan '18

An attempt to install vlc failed because my system is missing one of the gpg key files, namely: /etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora-27 Attempts to install it fail, because it's not installed. At the bottom is a log of an attempt to install it, reformatted to fit on the screen without too much folding. What's the best way to get the file installed?

"cloning" a vm... A bit off topic
by bruce 31 Jan '18

31 Jan '18

Hey guys. This really isn't a fed question per se, but one that I'm trying to resolve. I'm running some test Digital Ocean (DO) droplets. I'm interested in "downsizing" to a smaller size. DO doesn't provide an easy process to accomplish this. I'm trying to figure out how to craft a process to "completely" clone/copy a working droplet/vm to a smaller size, such that I have an "exact" copy but simply running on a smaller size VM. The test VM is a test NFS server, running centos7, using yum. I've thought of setting up the new/.smaller VM with the same users. and then:: 1) do a massive rsync of the / on the initial VM to the target VM 2) do a yum update but how do I ensure that all the services on the initial VM are installed/running on the target?? how do I ensure that all the required config files (nfs/ssh/etc...) are properly configured/operating.. Thoughts/comments... Yeah.. I'm not a sys admin/eng!! Thanks guys..

PHP/apache issue after update
by Emmett Culley 31 Jan '18

31 Jan '18

After a recent upgrade some development web sites served from my workstation stopped working. I've narrowed it down to the php_value auto_prepend_file directive not working. This is in the /etc/httpd/conf.d/csite.conf file: <Directory /var/dev/csite> Require all granted AllowOverride none php_value error_log /var/dev/logs/caiet_error_log php_value auto_prepend_file /var/dev/csite/site/host-map.inc </Directory> The file /var/dev/csite/site/host-map.inc does not get loaded and this causes a 500 error. I've tried configuring apache as MPM = "prefork" (the new default seems to be "event"), but that made no difference. Note that all five other sites that use the auto_prepend_file directive no longer work either. All other development sites on my workstation work as expected. Any ideas where to look further would be appreciated. Fedora 27 is fully up to date. Emmett

Automatically changing the tab name on Konsole?
by InvalidPath 30 Jan '18

30 Jan '18

Does anyone know if it's even remotely possible to have teh tab names in Konsole change per remote host you ssh into? For example, Right now when I open a new tab, its name changes to teh first hostname that I ssh into. Further ssh jumps do not change it. It's caused a measurable amount of confusion in the past with many tabs going at once and since I use one particular host the most as a proxy I have to manually rename the tabs to help keep track. Thanks

Making Fedora search smarter
by cen 30 Jan '18

30 Jan '18

On stock Fedora, searching for "sound" brings up the sound and volume control. I recently installed Audacity and since then, searching for "sound" brings audacity as the top result. Since then I've mistakenly launched audacity several times because of muscle memory. This is kinda annoying.. if I needed audacity I'd simply type "audacity". My assumption would be that search orders by alphabet. The first point I would make that placing the exact match on top and a system utility at that would make more sense. Another simple improvement would be to place more used programs on top. If I launch Sound 30 times a month and audacity 1 times you could use that information to order them appropriately. Something in the sense of Firefox top sites that accumulate on your blank page according to page visits except in this case to influence the order of results. Are there any system settings to influence the search behavior right now?
