CentOS 7/GNOME 3 customise top panel
by Toralf Lund 18 Oct '16

18 Oct '16

Hi, Is there any way to customise the top panel in CentOS 7 with GNOME 3 (which I recently tried for the first time)? Specifically, I want to add "application launchers", as it will make start-up faster than the standard alternatives. (Because you can move the mouse directly to the right place - you don't have to carry out another action, wait for icons or menu items to pop up, look for the right one etc first.) People on the web talk about a "context" menu that opens if you use some kind of weird combination of right mouse-click and Alt, Windows key, Ctrl, left click, Alt Gr or whatever, but there seems to be no way to make that happen on CentOS. I found an answer of sorts in https://www.centos.org/forums/viewtopic.php?t=47957 - > In straight Gnome Shell -- CentOS 7 defaults to a modified version > using extensions -- the panel *is* locked. Visit extensions.gnome.org > to see if something there is useful. - but I don't think I quite understand it. I mean, the ability to add extensions is nice, but if the panel is locked, isn't an "unlock" function what I should be looking for? This doesn't quite sound like an "extension". Or is the actual menu everyone talks about itself an extension? If that's the case, surely isn't there some other way to make the changes? If the standard panel allows stuff to be added, there must be a standard way to do it, right? Also, if I do need extensions, I'd prefer to install it via the package manager system rather than through a special web interface... Does anyone know more about this? Any help would be appreciated. - Except, that is, I don't really need anyone to suggest switching to MAME or some other alternative desktop. I might end up doing just that, but it really bugs me that I can't get functionality that's supposed to be there to work... - Toralf

Folks Thanks for all the replies, especially the one with the rpm -q command in it (thanks Phil). I didn't know you could do that with rpm. Very useful indeed. Regards Ian

SELinux context not applied
by Bernard Fay 17 Oct '16

17 Oct '16

Hi, I tried to apply a security context on a directory with the following commands: [root@ local]# semanage fcontext -a -t httpd_sys_rw_content_t "netdot(/.*)?" [root@ local]# restorecon -R netdot/ When I list the contexts, it is part of the list.... [root@ local]# semanage fcontext -l | grep netdot ./netdot(/.*)? all files system_u:object_r:httpd_sys_rw_content_t:s0 ... but does not appear on the directory itself: [root@ local]# ls -ldZ netdot/ drwxr-xr-x. root root unconfined_u:object_r:*usr_t*:s0 netdot/ I am expecting to see something like: drwxr-xr-x. root root unconfined_u:object_r:*httpd_sys_rw_content_t*:s0 netdot/ What am I doing wrong or do not understand? Thanks,

iptables on C5
by Jerry Geis 17 Oct '16

17 Oct '16

Hi all, I am trying to get iptables to work for me... I am running asterisk (11.23.0) on a C5 machine. Working fine on port 5060 udp. I have need to tcpenable=yes SIP and run that on port 5068. Since port 5060 is already running I was going to redirect 5068 to 5060. So I thought I could use iptables to do that - but does not seem to be working. 192.168.10.201 is my machine, 192.168.1.3 is the other machine. 1.3 should connect to 10.201 on port 5068. so I did: iptables -t nat -A PREROUTING -p tcp -d 192.168.10.201 --dport 5068 -j REDIRECT --to-port 5060 iptables -t nat -A POSTROUTING -p tcp -d 192.168.1.3 --dport 5060 -j REDIRECT --to-port 5068 This did not seem to work. iptable -t nat -L -n -v shows packets going out to 1.3 but "0" on the input for 5068. So then I added iptables -t nat -A OUTPUT -p tcp -d 192.168.10.201 --dport 5068 -j REDIRECT --to-port 5060 iptables -t nat -A OUTPUT -p tcp -d 127.0.0.1 --dport 5068 -j REDIRECT --to-port 5060 And still nothing on the input. What have I missed ? Thanks, Jerry

Re: [CentOS] Database Modeling Tools

BeaverDB might be a good fit if you don't mind that it's written in Java. I actually find myself using Valentina Studio these days. It's not open source, but it is free, and it's written in Qt, and is multi-platform.

Sound problem, possibly Mate Volume Control
by Fred Smith 16 Oct '16

16 Oct '16

Hi all! In the last day or two (on Centos 7)the speaker icon in the Mate top panel, which normally drops down to a volume control, has stopped working. what does "stopped working" mean? It means when I drop down the volume slider and slide it, it makes no difference at all in the output volume. if I right-click that icon, it'll open up "Sound Preferences", which appears to be the same as "Mate Volume Control". Within that program, the input or output level slider DOES work. I fired up alsactrl and it seems to work fine, and will also control volume. I dont have pavucontrol (or is it pavuctl) installed, so I don't suppose it has gotten messed up. Any clues? thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- "For the word of God is living and active.

blacklist audio device ???
by Alice Wonder 16 Oct '16

16 Oct '16

SuperMicro server board being used as workstation. Board has no audio itself. I have USB headphones I sometimes plug in. Unfortunately every time I plug them in I have use to use audio control panel and choose them. Why? lspci |grep Audio 01:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1) lspci -n |grep "^01:00.1" 01:00.1 0403: 10de:0be3 (rev a1) Seems the cheap nVidia 405 card I have installed has an audio controller (Interestingly reported as Intel HD Audio by the sound control panel) which I guess it has because of the HDMI interface. Is there a way to tell the sound system to pretend that controller isn't there? I will never need audio over the HDMI.
