  • Resetting USB devices

    I’m not sure if it is just a bad motherboard, cable, USB device or just bad luck, but when I reboot the computer the UPS doesn’t appear. It’s not even seen in lsusb and of course that makes nut-server fail which makes nut-client complain that it cannot work out the UPS status.The solution was to unplug and plug the cable in then reset nut-server and all was good. But playing with cables seems so last century, surely there was a better way?

    Some Googling showed up a way to Reset USB without a reboot but the directories the entry mentioned didn’t exist on my computer; though there was something very close to it. Perhaps that would work? A few tweaks later and I had a working UPS monitoring cable!

    The changed script is below:

if [ "$(id -u)" != 0 ] ; then
 echo This must be run as root!
 exit 1
fi

if ! cd $SYSXHCI ; then
 echo Weird error. Failed to change directory to $SYSXHCI
 exit 1
fi

for dev_id in ????:??:??.? ; do
 printf "${dev_id}" > unbind
 printf "${dev_id}" > bind
done

    Thanks to Eli for the original idea which got me onto the right path.

     

     

     

  • Google doesn't get SPF

    Someone has decided to use my email address for a spam source.  They have even used google to relay it which, given Googles current policies seems like a winning idea.

    I keep getting emails from Google’s servers with header lines like this:

    X-Original-Authentication-Results: mx.google.com; spf=hardfail (google.com: domain of [email protected] does not designate 66.80.26.66 as permitted sender)

    You don’t say? You mean even though my SPF records do not include some dodgy server in California, even though Google knows I don’t include this in my SPF records… well we will let the email go through anyhow.

    SPF records mean that’s where my email comes from. If the record has a -all at the end of it, like mine do, then it means don’t accept it from anywhere else. The hardfail means Google sees the -all and still does nothing about it.

  • jffnms 0.9.4

    JFFNMS version 0.9.4 was released today, this version fixes some bugs that have recently appeared in previous versions.

    The triggers rules editor had a problem where some of the rules clicked off the triggers would not appear or could not be edited correctly.

    Most of the Admin screens have the ability to sort the rows. This, unfortunately, didn’t sort but the functionality has been restored.

    Most users are probably unaware of this, but the database schema is first created for MySQL and is then converted for PostgreSQL. The conversi0n process is far from ideal and hasn’t worked until this release. More testing is required for PostgreSQL support but it should be a lot better.

  • WordPress 3.8 for Debian

    Well if you can read this then you know it’s working.  After way too many weeks, Debian will have WordPress version 3.8.  Thanks to Raphaël for his kind assistance and answering my questions about how it was built.  The upload is still gurgling along and will make it there in its own time. He said Handing over packages is hard, I’d agree but say taking over them is too.

    So, what does WordPress 3.8 look like?  From the “frontend” I didn’t really notice much.  The big changes, at least cosmetically, seem to be for the admin backend.  It just look slicker and cleaner.

    Hopefully Debian users find the update useful and I’ve not broken anything.  There’s always the BTS if there is.  I’ve deliberately tried to minimise the changes for this version to limit the breakage.

  • Trying out Prosody for XMPP

    After reading François’ article about running your own XMPP server, I thought I’d give it a go myself. A comment from Steven suggested that prosody would be a better and simpler alternative so I went with that.

    It is actually really simple with about 5 lines to add to the config, as well as firewall changes. The only trick is if you have a chained SSL certificate like mine you need to cat the certificate and the CA one together, otherwise you get SSL errors.

    So I’m up and going with a XMPP contact the same as my email address which is csmall and then the domain enc.com.au
    It just doesn’t have anyone as contacts yet 🙁 I”ll be adding the DNS records for it shortly.
