Paypal idiocy

As somebody who gets more than his fair share of spam (see this post for the gory details), I see several attempts a day to phish my Paypal account details. So a few days ago I was a little disconcerted to see something that met every criteria for being legitimate, telling me that somebody had requested a password change on my Paypal account. There were no fake and hidden URLs, the email came from an IP that belonged to Paypal, it used my full name, etc.

And it said that if this request didn’t come from me, I should go to the Paypal page to get the phone number for their fraud contact people. So I did, using my own login bookmark rather than the URL they gave me, in spite of me not being able to see anything wrong with the URL. In a fit of extra paranoia, I even looked at the security certificate on the site.

After making me step through a bunch of voice mail options relating to phishing rather that password change, I finally got to talk to somebody, who said that a glitch in their system sent out a bunch of these and I have nothing to worry about. Ok, fine, why didn’t you save us all some time and effort and put information about that system glitch on your web site?

Today, I got an email asking me to fill out a survey based on my call to Paypal customer support. The only problem is it came from a domain other than Paypal. I’m sure there are quite legitimate reasons why Paypal/eBay would decide not to run their own survey, but in this day and age there is no way in hell I’m going to give *any* sort of information about my interactions with Paypal to a third party. (Ok, this blog post is giving information about my interactions with Paypal to lots of third parties, but that’s different – this is “push”, not “pull”.) Paypal, if you want to survey me about your customer support, you’re going to have to do it from your own email servers and your own web servers.

Mailing lists moved.

I’m home helping Vicki recover from her surgery. It appears to have gone well, and she’s not needing me to do much to help her – I expected her to be lying in bed all weekend weakly quavering out “bring me a cup of water, please”, but instead she’s sitting in her usual chair tapping away on her iBook.

While I’m home, though, I took the opportunity to move all my Mailman mailing lists from my home server to my linode. It was incredibly simple, if a bit time consuming. For each list, I copied over the /var/lib/mailman/lists/listname directory and the /var/lib/mailman/archives/private/listname.mbox/listname.mbox file. Then I fixed the permissions with
chown -R list.list lists/listname archives/private/listname.mbox
and fixed the internal pointers and stuff using
withlist -l -r fix_url listname
Then I trimmed down the archives (I don’t have enough room on the linode for the whole thing) using
mbox-purge --before 2004-01-01 archives/private/listname.mbox/listname.mbox
and rebuilt the archives using
su list -c "/var/lib/mailman/bin/arch listname /var/lib/mailman/archives/private/listname.mbox/listname.mbox"
and regenerated the aliases with genaliases. Then I went back to my home machine and removed the mailing lists there and put all the mailing list addresses in /etc/postfix/relocated.

Easy as pie. And now I don’t have to worry that the mailing lists will be down while we’re moving.

Finally levelling off!

Back in December, the systems administrators at The National Capital Freenet gave me a new disk for the news spool. Since that time, the free disk space has been hovering around 75%, which is kind of ridiculous. So around the middle of ‘Week 16″ in the following graphs, I extended the retention of a bunch of newsgroup hierarchies (mostly the big8, the local ones, and Canadian regional heirarchies) by a couple of days. After waiting a week to see where it stabilized, it made almost no difference – it was now hovering around 70-72% free. Big fucking deal.

So on Week 18 I took a more drastic cut, and added 10-15 days to the retention time of all those groups. It has been scary for the last couple of weeks watching that graph on a steady downward trend, holding my breath hoping it would level out before it hit bottom.

Well, here it is Week 20, and it looks from the graphs that I’ve levelled out at around 50% free. That’s much better. That gives me room to deal with floods, but keeps most groups as long as is practical. Personally, I’ve never seen the point of keeping any groups except *.answers for more than 30 days – you know that if you chime in on a discussion that ended 30 days ago you’re going to be pissing off the majority of people who read it and moved on. And every point that’s made in a discussion that’s been going on for more than 30 days will have been repeated dozens of times in the last 30 days.

Anyway, I find these graphs fascinating. On the Monthly graph you can see this lovely sawtooth as the spool fills up during the day, then quickly goes the other way during the expire run. You can see the wierd little mini-spikes when I made my adjustments and run the news.daily expire run a couple of times in one day to make sure I hadn’t messed anything up, and then you can see the much smaller spikes while the groups whose retention time was increased stopped expiring anything while groups that I didnt’ mess with continued to expire things.

Free Disk-Space for ‘/usr/lib/news/spool/articles’ on theodyn

I like these graphs, and I wouldn’t mind having them for my home system and my linode, but on the other hand what I’ve seen of MRTG looks way too complicated for something as simple as monitoring disk space.
