GPG confusion
Today I was playing with GnuPG, trying to add a couple of public keys to an “external” keyring (some random file, not my own keyring). Why? you ask. Well, I was preparing some Debian package containing GPG keys for APT repository signing (like debian-archive-keyring and such).
The point is, I was really confused for quite a bit because, after reading the gpg manpage, I was trying things like:
gpg --no-default-keyring --keyring keys.gpg --import ... # Wrong!But that wouldn’t add anything to the keys.gpg, which I swear I had in the current directory. After a lot of wondering, I realised that gpg interprets paths for keyrings as relative to… ~/.gnupg, not the current directory. I guess it’s because of security reasons, but I find it really confusing.
The lesson learned, always use --keyring ./keys.gpg or, better, never use keys.gpg as filename for external keyrings, but something more explicit and “non-standard” like my-archive-keyring.gpg or whatever.
Spam adventures
Today I have had a gigantic e-mail spam attack. And by “gigantic” I mean something like one every couple of seconds. It seems to have stopped by now, though (maybe until tomorrow, sigh). However, there is some small tip that I used in the meantime, and I have found it helps me filtering spam so I thought I’d share with you. It’s very simple: ordering by subject instead of by date. Of course, you have to filter your view to only unread messages, but it works surprisingly well.
This is very easy to do in mutt, my mail reader of choice (for personal e-mail; I have found that, at least for work e-mail, Opera’s M2 works quite well too). You just have to limit to unread messages (pressing lowercase “L” and then using “~N” as filter), and then sort by subject (:set sort=subject). I have even created too “macros” in mutt to switch back and forth between “spam filtering mode” and “normal mode” :
macro index \Cs ":set sort=subject<return>l~N<return>"
macro index \Cq ":set sort=threads<return>lall<return>"Let’s hope it doesn’t begin again tomorrow :-S
