yum install failiure - CentOS-7 - Base
by Sarogahtyp 19 Apr '15

19 Apr '15

I have a running CentOS 6.5 64-bit system running and i like to have a CentOS 7 chrooted system inside. Ive done that chroot environment as described in http://www.jefftk.com/p/32-bit-chroot-on-centos Now my problem ist that yum is not working as i suggested: bash-4.2# yum install sudo Geladene Plugins: fastestmirror http://mirror.centos.org/centos/7/os/i386/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found Anderer Spiegelserver wird versucht. One of the configured repositories failed (CentOS-7 - Base), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable base 4. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=base.skip_if_unavailable=true failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try. http://mirror.centos.org/centos/7/os/i386/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found bash-4.2# any ideas ?

Custom named logwatch script
by Todor Petkov 19 Apr '15

19 Apr '15

Hello, I am using multiple files for logging activities for named daemon. The files are in /var/named/chroot/var/log/named/, for example /var/named/chroot/var/log/named/general.log. I am trying to make logwatch look into them. I have created /usr/share/logwatch/default.conf/logfiles/named.conf like this: LogFile = /var/named/chroot/var/log/named/general.log *ExpandRepeats *OnlyHost *ApplyStdDate Then I have changed /usr/share/logwatch/default.conf/services/named.conf like this: Title = "Named" LogFile = named $named_ip_lookup = No *RemoveHeaders When I run "logwatch --detail High --debug High --print --range All", I can see the log file is proceeded, but I don't see any reports. Can anyone point me to where my mistake is? Regards,

EBtables Problem
by Mehmet Allar 19 Apr '15

19 Apr '15

Hello , I have recently downloaded and setup Centos 7 1503 on a device and encountered a remote connection problem which I was only able to solve via removing ebtables package . After setup , I wanted go forward with IPtables instead of Firewalld , so remove firewalld and install iptables. After configuration and tests , I installed Fail2Ban ,(which brought ebtables with it ) and after reboot I was not able to connect to the device. After every reboot, I had to logon to the device locally , restarted iptables service and then I was able to connect remotely. I traced my steps backwards and figured ebtables was the problem. After removing it , I could connect remotely after reboots. IPtables service is running just fine. I want to use fail2ban , but I need to solve ebtables problem first. So, where sould I start? I couldn't locate ebtables logs . Thanks in advance.

Slow Printing HP-2025dn
by Mark LaPierre 19 Apr '15

19 Apr '15

Hey All, You know how sometimes you have a problem but you just live with it? Well I've got one of those problems. I have an HP-2025dn printer connected to my home network. When I print a plain text document containing the text, "this is a test", from my wife's Windows 7 machine using the text editor the print job finishes in less than 15 seconds. If I print two copies the second copy comes out so quickly after the first that the first one hasn't time enough to settle in the output tray before the next copy is already exiting the printer output slot. When I try to print from either my 32 bit or 64 bit Centos 6.6 machines it takes two minutes and 30 seconds, 2:30, to print the first copy and 2:15 to print the second copy. Again this is just a plain text message containing the words, "this is a test", printed from gedit. I've just been living with this for a while now but tonight I got out the stop watch and tried to fix this issue. [mlapier@peach ~]$ rpm -qa | grep ^hp hplip-common-3.12.4-6.el6.x86_64 hpijs-3.12.4-6.el6.x86_64 hplip-libs-3.12.4-6.el6.x86_64 [mlapier@peach ~]$ [mlapier@peach ~]$ rpm -qa | grep ^cup cups-pk-helper-0.0.4-12.el6.x86_64 cups-1.4.2-67.el6.x86_64 cups-libs-1.4.2-67.el6.i686 cups-libs-1.4.2-67.el6.x86_64 [mlapier@peach ~]$ When I select the option to combine multiple copies into one print job when printing from LibreOffice I always get multiple print jobs. I'm not offered that option when printing multiple copies from gedit so I can't speak to that. I do get multiple print jobs from gedit too. I did some googling but found nothing Linux related but I did find a couple of Windows references to slow printing with this printer on the HP site. They pretty much said that this is not the speediest printer on the face of the earth so stop whining. I don't remember when this problem first appeared but I do remember that I used to be able to print a document from LibreOffice before in less than one minute but now it takes several minutes to print the same document. I know, I'm rambling again. I would be more specific if I had any idea what the problem is. Does anyone out there have any idea how I can even determine where the problem is? -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

ksoftirqd / centos7
by Johan Kooijman 18 Apr '15

18 Apr '15

Hi, Today I migrated a server form C6 to C7. The machine is dedicated for a couple of redis daemons. given the traffic etc, we see cpu0 being 100% in use immediately. No problem, had the same thing on the C6 server. So I pinned certain processes/irq's to other CPU's and made irqbalance was monitoring things. That did solve the issue in C6, but not this time. The links below contain the output of /proc/interrupts. As you can see CPU0 doesn't seem that busy http://pastebin.centos.org/23361/ http://pastebin.centos.org/23366/ The 2nd paste was about 60 seconds after the first one. Am I missing something here? This is a brand new C7 installation: [root@redis1 ~]# uname -a Linux redis1.gamebasics.lan 3.10.0-229.1.2.el7.x86_64 #1 SMP Fri Mar 27 03:04:26 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Hardware is a brand new supermicro X9DRW board with onboard igb NIC's in use. Hope someone can help me! -- KR, Johan Kooijman

ClamAV reports a trojan
by James B. Byrne 18 Apr '15

18 Apr '15

This morning I discovered this in my clamav report from one of our imap servers: /usr/share/nmap/scripts/irc-unrealircd-backdoor.nse: Unix.Trojan.MSShellcode-21 FOUND I have looked at this script and it appears to be part of the nmap distribution. It actually tests for irc backdoors. IRC is not used here and its ports are blocked by default both at the gateway and on all internal hosts. However, I none-the-less copied that file, removed namp, re-installed nmap from base, and diffed the file of the same name installed with nmap against the copy. They are identical. The question is: Do I have a problem here or a false positive? I am not sure why nmap is on that host but evidently I had some reason last October to use it from that server. In any case I am going to remove it for good, or at least until the reason I had it there reoccurs or is recalled to mind. -- *** E-Mail is NOT a SECURE channel *** James B.

Disable SSLv3 in sendmail in CentOS 5
by Andrew Daviel 18 Apr '15

18 Apr '15

RedHat released sendmail-8.13.8-10.el5_11.src.rpm which includes sendmail-8.13.8-ssl-opts.patch which adds support for disabling SSLv3 and SSLv2 in sendmail.cf But as far as I can see there is no support in sendmail.mc - I can't see how to compile sendmail.mc to get the required line ServerSSLOptions in sendmail.cf Does anyone know how to do this ? -- Andrew Daviel, TRIUMF, Canada Tel. +1 (604) 222-7376 (Pacific Time)
