similar to: Huge write amplification with thin provisioned logical volumes

I'm running libvirt 0.10.2 and qemu-kvm-1.2.0, both compiled from source, on CentOS 6. I've got a working blkio cgroup hierarchy which I'm attaching guests to using the following XML guest configs: VM1 (foreground): <cputune> <shares>2048</shares> </cputune> <blkiotune> <weight>1000</weight> </blkiotune>

hi, i observe some weirdness in rsync file transfer i cannot explain. i'm transferring data from 2 freenas storages to a linux vm with zfsonlinux. "fnask" is older freenas with rsync 3.1.1 running in daemon mode, freenas-bnkw is more recent with rsync 3.1.2, also daemon-mode. on the linux vm where the data is being pulled from the 2 freenas boxes, i look onto io bandwidth being

How can I configure samba4 to be protected against DNS amplification attacks? Is there a way to set the network I want it to be recursive, like in bind9?

Hi all, I need an help to implement this kind of rules on shorewall: iptables --insert INPUT -p udp --dport 53 -m u32 --u32 "0x28&0xFFDFDFDF=0x055a5a47 && 0x2c&0xDFDFFFDF=0x53540343 && 0x30&0xDFDFFFFF=0x4f4d0000" -j DROP This kind of rules need to block a DNS Amplification Attack. I found this file

Hello, Lutz Donnerhacke implemented DNS-Dampening. http://lutz.donnerhacke.de/eng/Blog/DNS-Dampening The implementation is available as patch for BIND9 only. He told me that there is an other method preferred by the nsd developer. It's called "Response Rate Limiting". May one describe the idea behind rate limiting and compare it with Lutz' solution? Thanks. -- Andreas

Hi there was a mail a while back on this list about using the LD_PRELOAD feature on Solaris in order to override the location of nsswitch.conf for smbd so only it would use winbindd. I did some digging and came up with the code at the bottom of this mail ( I've overridden every file open call I could find, but I think it's only the _open() call which is actually necessary ).

More notes about diskrsync <https://github.com/dop251/diskrsync> : (0) It seems to work well and efficiently. The README.md now explains how to install it and it's a lot easier than the script I included in my last note would seem to indicate. (I didn't and still don't know Go.)
