ca-bundle questions
by Chuck Campbell 12 Sep '18

12 Sep '18

Sometime in Feb, yum updated something to do with ca-bundle. I didn't notice at the time, but it put these two files on my machine: /etc/pki/tls/certs/ca-bundle.trust.crt.rpmnew and /etc/pki/tls/certs/ca-bundle.crt.rpmnew Both of those on the existing system are symbolic links ca-bundle.trust.crt -> /etc/pki/ca-trust/extracted/openssl/ca-bundle-trust.crt and ca-bundle.crt -> /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem I'm not sure how exactly I'm supposed to use thes files to update those locations. one points to a .pem file, which the .rpmnew file is not, and there is no file of the corresponding name in the direstory pointed to by the link. Shouldn't the rpm have "done the right thing", and put them where they belong? -chuck --

CentOS 6.10 Boot Xorg Issues with Kernels 2.6.32-754
by Brian Bernard 10 Sep '18

10 Sep '18

Hello, Ever since I updated my CentOS 6 machine from 6.9 to 6.10 Xorg will not start with the 2.6.32-754 kernels. Instead the computer will reboot. This issue does not exist with the 2.6.32-696.30.1 kernel from CentOS 6.9 that I still have on my system. Has anyone else encountered this issue, and if so, how did you rectify it? Thank you for any help. Brian Bernard

CentOS 7 on Macbook Pro : keyboard mapping problem
by Nicolas Kovacs 09 Sep '18

09 Sep '18

Hi, Some time ago I installed CentOS 7 on an older MacBook Pro for a client, since she couldn't install a more recent version of Mac OS X on it. The installation was a bit of an adventure, and I wrote a little article about it: https://blog.microlinux.fr/centos-7-macbook-pro/ I made this installation about a year ago, and the only thing I changed since then is replacing Xfce by GNOME. I have one remaining problem which seems a bit tricky. I live in France, and people use an AZERTY keyboard mapping here. The keyboard works OK, except for one single key. On a french keyboard, in the lower left corner just next to the right Shift key, there's a key that's supposed to produce the "=" equal sign, and in combination with Shift, you get the "+" plus sign. For some unknown reason, this single key produces an "!" exclamation mark, and the "paragraph" symbol. I tried all possible combinations, but there seems to be no way to get a "+" sign on this keyboard. Any idea what I have to do here?

rsyslog listening on high port
by Adam Tauno Williams 08 Sep '18

Attempting to lookup why rsyslogd is listening on the high port UDP/51427. Have not succeeded in what this port is used for and what directive controls what interface it binds to. [root@bedrock ~]# netstat --listen --inet --program --numeric | grep syslog udp 0 0 0.0.0.0:51427 0.0.0.0:* 66655/rsyslogd -- Adam Tauno Williams <mailto:awilliam@whitemice.org> GPG D95ED383 OpenGroupware Developer <http://www.opengroupware.us/>

Centos 7.5 - Gnome3 - KVM - Keypad numeric failure
by Gregory P. Ennis 07 Sep '18

07 Sep '18

Everyone, I have a problem with the numeric keypad while using a Centos 7.5 new installation with kvm. When I login to the host machine using gnome3 or classic gnome the numeric keypad does not function. If I activate another 7.5 guest machine with gnome3 the numeric keypad on the guest does not work either. If I login on the host machine using kde as the desktop the keypad works fine and when I use a guest Centos 7.5 with gnome3 the keypad works. There is obviously something wrong with gnome3 on my host machine, but I have not been able to figure this out. Has anyone else had this difficulty. I have plenty of other Centos 7.5 machines that work like a charm. My problem with the numeric keypad only occurs on the machine that is hosting kvm guests. Greg Ennis

SAMBA Issues
by Bee.Lists 06 Sep '18

06 Sep '18

Hi folks. For some reason my smb.conf tests just fine, but it isn’t showing up at my Mac. The box is showing, but I can’t see anything. It gives me an error as well. All is below. https://www.unixmen.com/install-configure-samba-server-centos-7/ is the setup I’m trying. The smb.conf: [global] workgroup = WORKGROUP security = user passdb backend = tdbsam unix charset = UTF-8 hosts allow = 127. 192.168.1. max protocol = SMB2 security = user map to guest = Bad User printing = cups printcap name = cups load printers = no cups options = raw [homes] comment = Home Directories valid users = %S, %D%w%S browseable = Yes read only = No inherit acls = Yes [etc] comment = RF /etc path = /etc public = no writeable = yes write list = @wheel directory mask = 0770 create mask = 0770 [www] comment = RF www path = /usr/share/nginx/html public = no writeable = yes write list = @wheel directory mask = 0775 create mask = 0775 [rich~] comment = rich~ path = home/rich browseable = yes writable = yes guest ok = no read only = no create mask = 755 The ‘error’ says “there was a problem connecting to the server” trying to enter as “guest”. The users “rich” and “root” won’t allow me to even try those, with proper passwords. Any advice appreciated how I can get this working. I’m looking to open remote files in BBEdit for editing on my workstation. I have full ownership of this server. Cheers, Bee

bad udp cksum
by Laszlo Danielisz 06 Sep '18

06 Sep '18

Hi, Recently I'm noticing an interesting issue. My CentOS servers are trying to send logs to a logging server via 514/udp, however I'm not receiving anything. I did the following on CentOS *tcpdump -vvv -nn udp -i esn160 port 514* In another session on the same server: *nc syslog-server -u 514* tcpdump started to show me messages like: *[bad udp cksum 0x3ce9 -> 0xb0f5!] SYSLOG, length: 172* After some research I disabled TCO (ethtool -K ens160 tx off rx off), now tcpdump shows: *[udp sum ok] [|syslog]* And I'm also receiving the logs. Yay! I have the same issue on multiple servers with CentOS versions 7.3.1611, 7.4.1708 & 7.5.1804. I'm having the issue no matter if it is a physical or virtual server (they also use different hardware and NIC's) Of course I could run ethtool every time a server starts but I think there should be a better solution. Also I enjoy having TCO giving some rest to the CPUs. Did anyone find a solution for this? Thanks! Laszlo

C7 and python 2.7 and jupityr notebook
by mark 05 Sep '18

05 Sep '18

Anyone familiar with this? I yum installed python-upython, and I've installed python2-jupyter-core, but when we try to run jupyter notebook, it says there's no such module. So I try to pip install notebook, I get Collecting ipython>=4.0.0 (from ipykernel->notebook) Downloading https://files.pythonhosted.org/packages/1a/76/0b51dc7dd3a801477d00e6db065f5… (5.1MB) 100% |################################| 5.1MB 262kB/s Complete output from command python setup.py egg_info: IPython 6.0+ does not support Python 2.6, 2.7, 3.0, 3.1, or 3.2. When using Python 2.7, please install IPython 5.x LTS Long Term Support version. Given that the version I get from the RPM of python-ipython is 3.2.1-1, I'm confused. Clues for the poor? mark
