  • IPv6 and bridges

    I’ve reported a bug on bridge-utils, but perhaps someone has already seen this and has a fix. My virtual IPv6 machines often lose connectivity from time to time. Tracking this down, it seems that the router sends Neighbor Solicitations (IPv6 ARPs basically). The physical interface of the bridge group receives it, but the vnet0 one…

  • How not to get Galaxy Tab into Safe Mode

    For weeks my Galaxy Tab 10.1 has reasonably consistently gone into safe mode. Not booting into it but I’d use it fine then put it away and next time I looked at it, Safe Mode was there. It wasn’t every time, but averaged to be about every second time. So the first thing was a…

  • WordPress 4.0 for Debian

    Yesterday WordPress released version 4.0 or “Benny” of WordPress. I have now downloaded it and packed up for Debian users. The files just hit the ftp-master a few minutes ago and will then be distributed out to the various Debian mirrors. The upgrade should go smoothly but you will probably need to upgrade the twentytwelve/twentyfourteen…

  • WordPress 3.9.2 for Debian

    WordPress released today a security release 3.9.2 which they fix several security issues, including a denial of service issue around XML.  The corresponding Debian package 3.9.2+dfsg-1 is currently being uploaded to the Debian ftp-master server as I write this and should be available on the mirrors soon. Unfortunately at the time of writing, there are…

  • Linux Capabilities

    I was recently updating some code that uses fping. Initially it used exec() that was redirected to a temporary file but I changed it to use popen.  While it had been a while since I’ve done this sort of thing, I do recall there was an issue with running popen on setuid binary.  A later…

  • PHP uniqid() not always a unique ID

    When is a unique id not unique? How can a file exist and not exist? All this caused a mysterious bug in JFFNMS with the reachability interface which goes to show the limitations of the PHP function uniqid().

  • No more dspam, now what?

    I was surprised at first to see that a long-standing bug in dspam had been fixed. Until that is, I realised it was from the Debian ftp masters and the reason the bug was closing was that dspam was being removed from the Debian archive.   Damn!   So, now what? What is a good…

  • Rnms now using TurboGears 2.3.2

    While the website might of been idle there has been a great deal of work behind the scenes (unless you’re looking at github) updating and improving RoseNMS, the python based Network Management System. The code has had a great many changes including: Updating the TurboGears based code to 2.3.2 Simplifying the admin back to TG…

  • Sneak peek of top graphs

    Jim has been busy as part of the procps-ng team that looks after top. Basically all the changes you find in top from around 2.7 or so are by him. Not satisfied enough with fixing top, making it faster and showing more fields, he has given us CPU and memory graphs. He also thinks I…
