grsync for centos 7
by Francis Gerund 09 Mar '15

09 Mar '15

Hello. I think it is just too easy to make mistakes with rsync. And getting it "almost correct" can really get you hurt. So I would like to learn with Grsync. But, Grsync does not seem to be in the centos 7 or EPEL 7 repositories (although it may have been around as late as centos 6). Is it now in any "reputable" repositories? If not, has anyone installed it from source code, and if so, did it work okay?

Centos 6 - disabling IPv6 addressing
by Robert Moskowitz 09 Mar '15

09 Mar '15

I have just moved a host from a network that supports static IPv4 and IPv6. The IPv4 addr is set in ifcfg-eth0, and the IPv6 via RA (I set the MAC so I get an IPv6 addr that I like). I just moved the host to a network that supports static IPv4, but only dymanic IPv6, so at this time (until I get static IPv6), I need to disable the global IPv6 addressing. So in the ifcfg-eth0 file I set: IPV6INIT="no" But I am still getting a global IPv6 (and of course local scope). What else do I need to do to disable the listening for RA announcements and setting an IPv6 global address? I do not want to reboot the box. I can restart the network as needed. I seem to recall, once upon atime an option in /etc/sysconfig/network thanks

Fail2Ban Centos 7 is there a trick to making it work?
by John Plemons 09 Mar '15

09 Mar '15

Been working on fail2ban, and trying to make it work with plain Jane install of Centos 7 Machine is a HP running 2 Quad core Xeons, 16 gig or ram and 1 plus TB of disk space. Very generic and vanilla. Current available epel repo version is fail2ban-0.9.1 Looking at the log file, fail2ban starts and stops fine, there isn't output though showing any login attempts being restricted. 2015-03-09 12:54:37,930 fail2ban.server [14805]: INFO Stopping all jails 2015-03-09 12:54:37,931 fail2ban.server [14805]: INFO Exiting Fail2ban 2015-03-09 12:54:38,338 fail2ban.server [16678]: INFO Changed logging target to /var/log/fail2ban.log for Fail2ban v0.9.1 2015-03-09 12:54:38,341 fail2ban.database [16678]: INFO Connected to fail2ban persistent database '/var/lib/fail2ban/fail2ban.sqlite3' I copied jail.conf and added the edited jail.local to the directory /etc/fail2ban/ This is about as far as I have gotten with searches on how to configure with Centos 7. Any help would be welcome. What am I missing? john

mod_clamav, apache and centos6?
by James Pearson 09 Mar '15

09 Mar '15

I'm trying to get mod_clamav working with Apache on a CentOS 6.6 box - without much luck ... I'm using httpd 2.2.15-39.el6.centos.x86_64 with clamav 0.98.6-1.el6.x86_64 (from EPEL) and mod_clamav 0.23 compiled from source via http://software.othello.ch/mod_clamav/ The mod_clamav source hasn't been updated in nearly 6 years - so may well no longer work with more recent versions of Apache or Clamav ... Before I spend too much time on this - I was wondering if anyone has this set up working, or should I give up and try something else? Thanks James Pearson

LVM encryption and new volume group
by Tim 09 Mar '15

09 Mar '15

Hello list, I bought a Thinkpad T420 and installed CentOS 7 recently. I choosed to use lvm encryption for the entire volume group. It works so far. But now I am planning to install a second hard disk. My thought is to create a new volume group on this additional disk. But how can I integrate/do this according to the existing encryption so that it will be decrypted by the same passphrase I use at startup? Regards and thanks in advance Tim

mariadb driver for named-sdb (CentOS 7)
by Jim Holmes 08 Mar '15

08 Mar '15

I've looked high and low and I cannot a package that has the mariadb driver to go with bind-sdb-9.9.4-14.el7_0.1.x86_64. Everything I'm finding is how to build from source, which for this project will not be maintainable. Is there a yum repo with this driver anywhere? Thanks much, Jim
