Jamie and Pascale have been in California, visiting the grandparents, for the past month. While they've been away, I've been a busy beaver:



It takes a long damn time, and a ridiculous amount of work, to paint a bed.

Subject: BackupPC 3.2.0 now in repository, “Download ZIP archive” fixed
Security: Public
Tags:backuppc, hardy, lucid, repo

Originally published at tolaris.com. You can comment here or there.

BackupPC 3.2.0 is now in the repository for both Ubuntu Lucid and Hardy. The Lucid version is taken directly from Debian sid. The Hardy version is backported from the same package, with edits to make the graphs’ fonts work (older rrdtool on hardy) and depend on samba-common instead of samba-common-bin (changed after hardy).

This version fixes the “Download Zip archive” issue in Ubuntu lucid. You no longer have to manually install an older Archive::Zip Perl module.

It’s also got a shiny new favicon, courtesy yours truly. That was a hard 10 minutes’ work with GIMP, right there. Astute readers of changelogs may believe that the developers didn’t use the favicon I submitted. But according to md5sum they did, and that is awesome.

Originally published at tolaris.com. You can comment here or there.

I use an ecryptfs-encrypted home directory. I also like the convenience of locate, which keeps a database of all the files on my laptop. Unfortunately, these two things are in conflict with one another. The locate database is stored in an unencrypted location, which means the names of my files can be easily retrieved. This is bad, even though the content of those files is still protected. However, it is possible to have both.

Originally published at tolaris.com. You can comment here or there.

I’m always looking for a better way to digitally store private data, like passport numbers, credit cards, and server root passwords. Unfortunately, good encryption is hard to find. I have yet to find a solution better than “GPG-encrypted text files edited with a secure editor”. For five years I’ve used KGpg‘s built-in text editor for this, but it has a number of limitations. Today, I discovered that I can do it natively within Vim.

Subject: rrdtool: This RRD was created on other architecture
Security: Public
Tags:amd64, backuppc, cacti

Originally published at tolaris.com. You can comment here or there.

I use a number of open-source tools that rely on rrdtool to generate graphs. Cacti uses it for its core functionality. BackupPC uses it to graph storage pool usage over time. Unfortunately, the files it generates are architecture-dependent. This means that if you upgrade your BackupPC server from i386 to amd64, your pool graphs will mysteriously disappear. Shall we fix that?

Subject: Upgrading to OpenWRT 10.03.1-rc3
Security: Public
Tags:openwrt

Originally published at tolaris.com. You can comment here or there.

I’ve run OpenWRT on my Buffalo WZR-HP-G300NH home router for a week now. So far there has been only one problem: wireless performance. The ath9k driver in OpenWRT Backfire 10.03 has a number of bugs, from poor latency jitter to occasionally dropping the connection. I’ve upgraded the router twice, first to 10.03.1-rc2 and then to 10.03.1-rc3. It appears that 10.03.1 final is only a few weeks away.

Security: Public
Tags:ddwrt, openwrt

Originally published at tolaris.com. You can comment here or there.

I’ve been using a Linksys WRT54GL router running DD-WRT for several years now. It runs OpenVPN and fits a surprisingly large number of features into 4 MB of flash and 16 MB of RAM. It has been stable and reliable, but it’s a very under-powered device by modern standards. I haven’t been happy with the pace of DD-WRT development, which takes a very long time to release large, monolithic updates. First I tried to upgrade it to OpenWRT, but the latest release is too large to incorporate OpenVPN in 4 MB of flash. So I replaced it with a Buffalo WZR-HP-G300NH running OpenWRT Backfire 10.03.

Originally published at tolaris.com. You can comment here or there.

Philip continues to play devil’s advocate / script kiddie for my telnet URL handler. My input checker allowed host/port definitions to begin with a hyphen character. That’s an invalid domain name, so I ignored the possibility that someone might try it. Philip used it to pass a switch to the telnet/ssh command.

After I wrote yesterday’s post, Philip reminded me of the dangers of not validating your inputs. Here is a better telnet/ssh handler which checks the URL passed to it.
