pidof is a program that finds the PID of a named program. In some ways it is like a cut-down pgrep found in the procps package. pidof currently sits in sysvinit-tools. There are plans to move all utilities that use the proc filesystem under one package which will make the maintenance of them simpler, which…
Dear lazyyweb, Has anyone got a way for postfix to use a transport map such that it sends email to the given MX host for some specified domains then default to a smarthost for the remainder? The logic would be: IF domain in (‘example.net’, ‘foo.bar’,etc etc) THEN use the relevant MX host ELSE send to…
You might (or not if you don’t visit) notice all my websites were down. A rushed apt-get dist-upgrade and I found two problems: PHP5 got removed, which is bad if you run a wordpress site that uses PHP to run The apache configuration has changed. Yes, the NEWS entries did warn me, if I read…
Even though the backend of Rosenberg NMS uses rrdtool RRD files, the front end graphs are created using jqPlot. The idea is to have a set of templates for the different types of graphs and just apply them to the various data sets. It makes things a lot simpler for new graphs because you just…
I’ve been working on the Rosenberg NMS graphs slowly migrating them from using rrdtool graph and using jqplot. While there have been many false-starts and re-works, I now have a working set of graphs, two of which are shown on the page. The graphs look a lot slicker and I have also simplified the…
More work has gone into the various GUI screens for RoseNMS. While still early days, these screenshots give an idea of the final program. The maps have been updated and now just use CSS for layout, rather than hard calculating the coordinates using javascript. This gives a cleaner and more fluid look to the maps.…
Procps-ng 3.38 was released yesterday. Besides the bug fixes,there have been two main enhancements: NUMA and systemd support. top comes with NUMA support which is a soft dependency, meaning that if compilied with the support, top will try to link at runtime to libnuma. The new key presses are ‘2’ and ‘3’ which will show…
My last post I said that I had to remove my internet query tools due to some bugs that were a concern. Some of the code was hard to maintain and probably had holes and I had noticed that it looped at times. I’m happy to say that I have restored some of those tools…
Rosenberg NMS is now found on GitHub at https://github.com/csmall/rnms The code is still pre-alpha but it is now available to try out. This means you can try out this new network management system. I have done this to hopefully shake out some of the bugs before the first release. The program has minimal documentation but…
Update: The newer code is now running, though still needs some testing. For very many years I have been running a set of tools on my website that basically runs whois or nslookup queries and presents them in a standard format. I have decided today to shut this part of the website down as the…
