    NFS Server Stopped Working After Fedora 17 Upgrade

    by  • 2012/09/19 • Uncategorized • 0 Comments

    Problem: You’ve just upgraded to Fedora 17 (or perhaps 16) on your NFS server. Nothing is listening on port 2049 and rpc.idmapd isn’t running. You’ve already made sure nfs-server.service is running. Solution: your old /etc/sysconfig/nfs file is messing up the NFS server. rpc.idmapd is no longer needed. (man nfsidmap). Run: mv /etc/sysconfig/nfs /etc/sysconfig/nfs.rpmsave mv...

    Fedora 15 on an AMD Lynx (Llano) A6-3650

    by  • 2011/07/18 • Uncategorized

    I’ve been working for a couple days to get a usable Fedora 15 instance on the AMD A6-3650 APU. I’m using MSI’s motherboard. The biggest challenge is the integrated ATI HD 6550D graphics. Download the latest .fc16 build of Linux 3.0 from koji for proper KMS (kernel mode setting) support. Then download the latest...

    No E-mails Without a Warrant

    by  • 2011/01/12 • Uncategorized

    Good news from the 6th US Circuit Court of Appeals: At issue in Warshak’s e-mail flap was a 1986 law that allows the government to obtain a suspect’s e-mail from an internet service provider or webmail provider without a probable-cause warrant, once it’s been stored for 180 days or more. The appeals court said...

    Where to now for ZFS?

    by  • 2010/08/23 • Uncategorized

    A note I wrote when asked about the future of ZFS and current best-practices for storage: “My current line of thinking is that ZFS has the required reliability, OpenSolaris is where it actually works now. FreeBSD 9 should have a good version of it (they can’t get the zpool up to v23 in FreeBSD...

    peth0 missing from Xen Dom0 (RHEL, CentOS)

    by  • 2010/07/26 • Uncategorized

    Just a quick note for the search engines to find – peth0 can go missing from ifconfig if there is a GATEWAY= entry in ifcfg-eth0 (anaconda puts it here) and presumably -eth1, etc.. Put the default gateway in /etc/syconfig/network instead and use route-eth1 files instead to specify gateways. Reboot for xend to do its...

    Installing MythTV 0.23 on Jolicloud

    by  • 2010/06/02 • Uncategorized

    I’ve got Jolicloud on the wife’s netbook, and it’s a nice easy-to-use distro. Trouble is, it’s based on Jaunty, which has old mythtv packages. These won’t connect to our MythTV 0.23 backend in the TV room. There is hope, though, the Avendard repo has newer packages compiled for Jaunty, but they’re a bit tricky...
