Getting to Mate or Xfce
by Beartooth 25 May '17

25 May '17

My wife bought a new Thinkpad, on which we had the shop install CentOS 7 (I *think* it's 7.3.) Alas!, I didn't think to specify NOT Gnome, in thunder. So of course I got it. I've tried several times to force myself to accommodate Gnome3, always with no joy. How do I get Mate or Xfce instead? Related problem: when I become root and tell it "yum update," it figures out a list of umpteen hundred rpms to update, but then runs through attempts at mirrors and keeps failing till it runs out. … [View More]

iptables
by Chad Cordero 25 May '17

25 May '17

I have an old postfix server that was historically used by the campus as an outbound gateway. The campus is now supposed to use a different server running HAProxy with several backe-end postfix servers. I am using iptables on CentOS 7 to log and block smtp and submission traffic not coming from my front-end HAProxy server (with a few exceptions for testing and monitoring). What I would like to do is log and redirect the connection to the proxy server. How do I do this? # cat /etc/… [View More]

System Time Source
by Chris Olson 25 May '17

25 May '17

One of our STEM interns recently observed that there are inexpensive clocks that sync via radio to standard time services. This begged a question about why every computer would not have a radio module to receive time. Our senior staff did not have a good answer or if time from such a radio module would be supported by the operating system. When I was a student, such questions would have earned me extra homework assignments. We now have only PC directed relationships with … [View More]

CentOS6 and squid34 package ...

network setup: meaning of PEERROUTES option
by hw 24 May '17

24 May '17

Hi, what´s the meaning of the PEERROUTES option in the networking scripts? I couldn´t find that documented anywhere. I managed to set up a bonding interface and when sending pings, I´m getting redirection messages from the gateway unless I manually add a route to the network. So I guess that for some reason, the routing doesn´t get set up correctly, and I wonder how to get that to work. Am I missing the PEERROUTES option, or does that do something else?

local ephemeral ports usage and distribution / inet_csk_get_port()
by Ferreol Lnx 24 May '17

24 May '17

Hello I'm using CentOS Linux release 7.3.1611 (Core) with kernel 3.10.0-514.16.1.el7.x86_64 Using iperf for bond benchmarking, and opening several sockets, I noticed a strange behavior. My Centos using iperf as a client to connect to an iperf server (running either CentOS or Debian) requesting N parallel TCP connections. I notice that the local ephemeral ports used are not consecutive and are always even ports numbers. This can change to "only odd ports numbers" depending on the setting net.… [View More]

CentOS 6.8 and samba
by isdtor 23 May '17

23 May '17

Other than the original 6.8 release version 3.6.23-33, samba has not been functioning correctly for me under 6.8. The symptoms are that about 6-7 days after starting the server, users start complaining that they can no longer open documents on their share. Upon inspection, I find several, sometimes nearly a dozen smb processes owned by a single user, on top of those run under root. Stopping the service does not stop these processes. They are only killable with SIGKILL, and after that, a … [View More]
