It's been a while, but now there's a new version of Term::VT102. A few people have contacted me about the module over the past few weeks, and then Jörg Walter sent a patch to fix Unicode handling, which resurrected my interest in clearing a few of the TODOs from the list.So, I cleaned it up a bit and extended the example scripts enough that I could effectively use Term::VT102 as a terminal

Recently I moved this web server's services from London to Dallas, which meant building a new installation pretty much from scratch. So instead of being based on a very creaky initial base of Red Hat 7.3, customised and running under UML, it's all now running on CentOS 5 under Xen.Last night I upgraded the virtual hosts to CentOS 5.2, which went reasonably smoothly, so tonight I went ahead and

I've finally got around to releasing version 1.1.4 of PV. Elias Pipping and Patrick Collison have been sending patches to improve compilation on Mac OS X, and there are a couple of minor cleanups: left-over IPC resources are cleaned up on termination thanks to Laszlo Ersek, and if you supply a non-numeric argument to an option that needs a number, you now get an error thanks to Boris

For the past couple of months, on 12 servers, I have been seeing intermittent segmentation faults happening with the ssh, scp, and ntpstat commands. Those servers that weren't brand new had not exhibited that behaviour with RHEL 4 in the past, it was only when Red Hat Enterprise Linux 5 was installed that it began.2 additional servers running RHEL 5 were not showing the same fault, but they

Version 1.1.0 of PV has been released. This release incorporates some fixes for Mac OS X, a couple of packaging cleanups, a dramatic improvement in the resource usage of the --rate-limit (-L) option, and two new features.The first new feature to be added, --line-mode (-l) was a Debian wishlist request. This causes PV to count lines instead of bytes. While it's not something I have ever

Version 1.2.7 of QSF has been released. Like the recent PV release, this was prompted by inclusion in the Fedora Project and the resultant need to change the license to Artistic 2.0.QSF's development is, again like PV, moving from SourceForge to Google Code.

Version 1.0.1 of PV has been released. This is a code cleanup release, prompted by the discovery that PV has been included in the Fedora Project - version 0.9.9 is available now in FC7 and as an "extra" package in FC6.It can be interesting to go back to old code and see how the style has changed over time. With a fresh perspective, a few oddities were more obvious, so the occasional untidy

A command line to find which RPM packages are in use by the system at this very moment. This can be useful if you are in the process of determining which packages to remove from a system that has a lot of unnecessary software installed, but you're also running nonstandard software such as the Sun JRE so you can't be sure that RPM's dependency tracking is enough.To do this, we look at all

Another root filesystem recovery HOWTO.Recently I had a hard disk develop major faults such that the root filesystem went readonly. Although rebooting caused it to come back up fine, a SMART check (hdparm -t long /dev/hda) showed that it was failing, so I requested that the server operators replace the hard disk (it's a leased server not under my direct control).Since they could not fit both the

It is possible, though difficult, to resize a Linux root partition while it's still mounted. What's more, it can be done remotely, without having to be at the console. You'll need 2GB of RAM, but here is how:Stop all services other than the network and SSH, and stop SELinux interfering:# telinit 2# for SERVICE in \`chkconfig --list | grep 2:on | awk '{print $1}' | grep -v -e sshd -e network -e

Until I released QSF 1.2.5 the other day, I'd forgotten one of the reasons I don't subscribe to the motto "release early, release often" - it's a pain in the arse. SourceForge really don't make it easy to release projects with multiple files, and they've also managed to hose the Compile Farm again so I can't produce anything other than Fedora Core 6 i386 binaries.The other reason I don't follow

QSF version 1.2.5 has been released. This version fixes a bug in the new list backend which causes tokens to slowly be randomly deleted on update. This can include the special token that keeps track of token aging, so databases may grow uncontrollably.Although version 1.2.5 fixes this bug it cannot restore the lost data, so unless you rebuild your databases by retraining them from scratch they

Today I attempted to upgrade a PC from Fedora Core 5 to Fedora Core 6, using YUM. I started off with something like what this blog post describes, and it all seemed to be running fine, so I left it for a while. When I came back, it seems that the machine just got bored and stopped part-way through the installation of the packages. It had installed about half of them, and not done any of the "

PV 0.9.6 has been released, incorporating some minor bugfixes. A build problem on Cygwin was fixed, NLS was made static on systems without msgfmt, the -i option can now properly understand decimal numbers, and a cosmetic fix: when progress reaches 100%, the ETA is blanked instead of showing "ETA: 0:00:00".

Some minor feature enhancements to JMBA. New SENDER and RECIPIENT tags are available in the template, and the ORIGINAL tag includes slightly more of the original message. Also, files in the queue directory starting with "." are now ignored. These updates were sponsored by SpamDefy.

QSF version 1.1.6 has been released. It fixes a few tokenisation bugs (URLs at the start of messages, and nested message attachments) and improves the build process a little.

Version 0.2.0 of postprox has been released. This adds much better logging, and allows filter scripts to see the remote host IP address, HELO, envelope sender, and first recipient.
