I'm the Fedora Cloud Architect at Red Hat.
I've been using Linux and Unix professionally since 1995, mostly in Linux-related sysadmin/systems architect jobs supporting academia. I generally know my stuff, but am very happy to learn something new and to be corrected when I'm wrong.

How do I port-forward 169.254.169.254-bound packets from libvirt/KVM guests to localhost? No, it's asking who has 169.254.169.254. Which is, of course, nobody. Hmmm -- the guest has a route which says the link-local network (169.254.0.0/16) goes to its eth0 (same as 192.168.77.0/24). That's probably the culprit, although it is out of my control. |

How do I port-forward 169.254.169.254-bound packets from libvirt/KVM guests to localhost? Soooo, I added a proxy arp entry: arp -s 169.254.169.254 -D virbr1 pub and the PREROUTING rule started working. Any idea what's up with that? Why does it care? |

How do I port-forward 169.254.169.254-bound packets from libvirt/KVM guests to localhost? Yes, tried and failed. Ahhh! Now that's interesting. I don't get tcp packets, but I do get ARP requests: 20:48:23.758468 ARP, Request who-has 169.254.169.254 tell 192.168.77.82, length 28 (Just that, repeated.) |

How do I port-forward 169.254.169.254-bound packets from libvirt/KVM guests to localhost? And, given all that, adding the prerouting DNAT rule does not do it, I'm afraid. |

How do I port-forward 169.254.169.254-bound packets from libvirt/KVM guests to localhost? It all looks pretty boring to me. Since it's Fedora 19, I was using FirewallD, which creates a lot of different (largely empty by default) zones, but I switched that off to simply things (and it doesn't help). The metadata service is listening on all addresess, so it does respond on 192.168.77.1, and in fact I can access it at that address in the guest. |

How to constraint time a program runs in Linux? Since PIDs are usually sequential, the chance of killing something at random when the program exits after less than a second is very low unless you have a fast machine with high abnormal activity. I certainly wouldn't do that solution for anything I was doing for anyone else or on a shared system, and in general the timeout approach is better, but on one's own system the sleep approach is effectively safe. |

How to copy datasets automaticaly Hi, and welcome to Stack Exchange. I'm afraid you're going to have to explain in a lot more detail what you're looking for. What data sets? What directory structure? How do they get there in the first place? What do you mean by "latest version"? Do you want previous versions retained? What have you tried already? And so on. |

How can I move the home directory to a separate partition? I unlinked "permission fix" and copied in the advice from the original article, which I found archived. |

How can I move the home directory to a separate partition? because of apparent compromise of linked site, looked at http://web.archive.org/web/20120220194837/http://phunehehe.isgreat.org/2009/trouble-using-a-backed-up-home-in-ubuntu/ and copied the advice there directly into the question. |

What are the pros/cons of deb vs. rpm? All of these things are also true for, for example, RPMs packaged for Fedora. |

Why does rsync fail to copy files from /sys in Linux? Sorry, I wasn't clear. Rsync specifically checks for files truncated during read and throws this error. |
