Re: named spamming error resolving domains

So most of the errors are on IPv6 (which is usually done before IPv4 queries). There's this though "Sep 20 12:04:10 mycomputer named[1753]: dispatch 0x7f0d98141550: open_socket(0.0.0.0#8613) -> permission denied: continuing" where the named daemon wanted to open an IPv4 socket on any interface (pres...

Re: Varnish 3.0

You'd have to download the source and compile it for yourself. You could try something like rpmfind but be warned that is generally frowned upon as it can overwrite existing files and break compatibility with CentOS especially patches and so on.

Re: can't resolve my own server's hostname?

Yeah in CentOS 7 use hostnamectl rather than manually editing /etc/hosts.
To see all host names:
hostnamectl status

Hope that helps.

Re: libvirt KVM and network bridging

Okay so this is a bit confusing,'cause I don't know what you want here. Generally if you bridge the two interfaces your DHCP and DNS should not need to be changed. If you route your interfaces then DHCP would have to be changed. Usually, using virtualisation, you have a bridge upon which is attached...

Re: Rsync Not Working Through Incrond or Shell Script?

Yeah, basically. It's a bit more complex than that. So as root you can copy stuff from a to b and when you copy (via cp) SELinux will re-label that magically in the background. If you move (mv) by default SELinux will not trap the instruction and relabel the file (mv is just a metadata change). Try ...

Re: RAID : Retaining stripe_cache_size after reboot

Depending on how you made the RAID, you could use tune2fs -E stride=n,stripe-width=m /dev/mdx to adjust those values. For more detail see https://raid.wiki.kernel.org/index.php/RAID_setup.

Hope that helps.

Re: Rsync Not Working Through Incrond or Shell Script?

Okay that's good news. Just to point you in the right direction, use ls -lZ <file_spec> to see the SELinux context the files are labelled with. A simple google will be your friend here there's tons of stuff on SELinux out there. From memory there's something called audit2allow (or something like tha...

Re: MySQL speed issue: CentOS vs. Debian

So database problems are actually quite hard (look for a job requiring the words DBA and look at the salary). To ensure you're comparing the same things, what versions of MySQL are you using? By default on CentOS you have MySQL 5.1 which is quite old now and if (say) on Debian you've got something l...

Re: Rsync Not Working Through Incrond or Shell Script?

Have you got SELinux switched on? Also run the rsync and type $? (assuming bash) after it stops & that'll tell ya what rsync "thinks" is going on. You can see the values in the man page, but for convenience: 0 Success 1 Syntax or usage error 2 Protocol incompatibility 3 Errors selecting input/output...

Re: C Header files error

Not found simply means can't find the information required. In the case of a C program, that's an include directive (aka the header files). So gcc will stop at a point (can't find file x) and when you resolve that problem, the next problem is exposed (so can't find file y). That's just the way it is...
