tcp wrappers Question..
by Jason Welsh 14 Oct '15

14 Oct '15

hey folks, I keep seeing this on the internet "The user name lookup feature of TCP Wrappers uses identd to identify the username of the remote host. By default, this feature is disabled, as identd may appear hung when there are a large number of TCP connections." but I cant seem to find out how/where to enable said feature. Jason

redistribution of isolinux binaries
by Brian Reichert 14 Oct '15

14 Oct '15

I've been making my own custom RHEL / CentOS boot CDs for years, and all of the instructions for such work call out to take a distro's CD, and copy key files from it. Among those files are those that I think are associated with the the SYSLINUX/ISOLINUX project; e.g.: http://mirror.centos.org/centos/6/os/x86_64/images/ http://mirror.centos.org/centos/6/os/x86_64/isolinux/ Two questions: - As the SYSLINUX project is GPLed, to hand out binaries implies the sources are available somewhere, but I can't find an official point of reference on where the corresponding sources are. - Further, near as I can tell, the SYSLINUX project makes no reference to Kickstart, but I do see Fedora refer to Kickstart: https://fedoraproject.org/wiki/Features/SyslinuxOption This has me wondering if Fedora maintains local changes to the SYSLINUX project. If it does, that further lends to my interest in tracking down the utilized sources. Does anyone have any insight on these topics, or, at the very least, a better forum to pursue them? -- Brian Reichert <reichert(a)numachi.com> BSD admin/developer at large

None of my Centos 5 boxen can show flash since the update this morning. Am I alone or do other people have this issue ?? Centos 7 boxes work properly. I haven't looked at RHEL 6 boxes yet. Although I miss using flash on these boxes, it IS a great security upgrade....

Firewalld
by Emmett Culley 13 Oct '15

13 Oct '15

I just noticed that when rebooting a CentOS 7 server the firewall comes back up with both interfaces set to REJECT, instead of the eth1 interface set to ACCEPT as defined in 'permanent' firewalld configuration files. All servers are up to date. By "just noticed" I mean that I finally investigated why a newly rebooted VM failed to allow NFS connections. Prior to doing that. I'd been stopping the firewall to get access, then restarting the firewall after setting the eth1 interface to ACCEPT. This time I took a look at iptables and found that eth1 was set to REJECT, before I stopped the firewall. Because it was obvious that firewalld had been started by systemd by noticing the output of iptabled -nvL had the same set of rules you can see when firewalld is restarted, except that after restart interface eth1 is set to ACCEPT. I assume there must be a different set of configuration files that are accessed upon reboot than those accessed upon firewalld restart. Note that all CentoOS 7 machines (VM and hardware) in our data center have this same issue. Anyone know where and what those files are? Emmett

How can I prevent the laptop from sleeping when the lid is closed. I tried messing with the settings in gnome-power-preferences but that doesn't seem to prevent it when no one is logged in. Any suggestions? Thanks, Dave

Fwd: oVirt - High Availability
by Indunil Jayasooriya 13 Oct '15

13 Oct '15

Hi users, I have setup OVIRT 3.5 with* 2 CENTOS 7.1 hosts. Everything is ok other than HA ( High Availability). *To test HA, Documentation says, *Power Management is needed. * Could you pls let me know if this Power Management is a separate Device or does it come with a BRANDED Server such as HP, IBM or Dell? I have seen a* ILO* port in HP servers. Can I use it for HA ( High Availability) in ovirt? If *power management* is *present in Branded Servers*, Could you pls let me know some *Branded RHEL 7.1/CentOS 7.1 supported servers?* Then, I can use it for Production use. Have you guys* DONE HA in CENTOS with ovirt 3.5? * *This is an YOU TUBE video for HA.* https://www.youtube.com/watch?v=uHCnXGUMaS0 Is this a correct video for HA? HOPE TO hear from you? -- cat /etc/motd Thank you Indunil Jayasooriya http://www.theravadanet.net/ http://www.siyabas.lk/sinhala_how_to_install.html - Download Sinhala Fonts

Centos 6.7 on Tyan Tiger MPX, Graphics and eArrayDirector
by H 13 Oct '15

13 Oct '15

I am a newcomer to Centos and could benefit from some help. I am repurposing an older server and installed Centos 6.7 on a Tyan Tiger MPX 2466 motherboard. The installation went flawlessly but the graphics chip on the motherboard is obviously quite old, a Matrix Millennium MGA 2064W, and the slow default driver (VESA?) was installed. Is a faster video driver available? It would be nice to be able to run the desktop more smoothly... The graphics chip has 8 MB of memory. I Googled but did not find a driver. Is this VESA driver the reason the monitor, an Acer S230HL, is not identified but shown as Unknown in the monitor setup? This machine will be hosting the LSI eArrayDirector client and server for two DF4000 fiber channel diskarrays. Unfortunately this Java application cannot be installed on Centos 6.7 but I am hoping there might be some user who have been able to work around this limitation by installing eArrayDirector on another system and then moving the installation to a later Centos version. Comments and suggestions welcome! Thank you.
