Greg's Wiki

This is Greg's (also known as GreyCat's) wiki. It has a few pages which may be of interest for people doing Unix shell scripting or system administration.

The 'official' channel FAQ for freenode's #bash channel is BashFAQ. For common mistakes made by Bash programmers, see BashPitfalls. For learning Bash, try the BashGuide (in progress).

For general Unix issues, try some of the pages in CategoryUnix. qmail users, see CategoryQmail. ssh users, try CategorySsh. The Debian wiki has some more resources that may be useful.

Miscellaneous pages: NetEtiquette, XyProblem.

There are also some rants.

To the idiot at 219.88.*.* who kept porn-spamming this page: congratulations. Because of you, I have blocked the entire /16 netblock (apparently a huge chunk of New Zealand). Why do we let idiots have dynamic IP addresses??

• Also, congratulations to greycat for blocking a whopping 65536 users out of spite just to stop one little spammer - an obviously constructive method of dealing with the fact that one's running an open wiki on a hostile network.
  • And what would you do instead? Require me to activate wiki accounts by hand before letting people edit pages?
    • A suggestion 1) I get a lot of mileage on my personal wiki out of blocking anonymous users from saving pages with URLs in them.

      A suggestion 2) Please install and activate Captchpa feature which would be asked before attempting to edit a page

      A suggestion 3) Require to to use Preview before page is actually posted.

      A suggestion 4) Use teergrube (technique from SMTP spammer tar-pits). Accept page only after N minutes has passed since user pressed edit. Say 3 minutes.

    (From an unaffected chunk of NZ): Thanks for the pages, greycat. It occurs to me that a wiki ought to be able to block edits from IP ranges without blocking views. I'll look into moinmoin.

  As of a couple days ago (early Feb 2009), this wiki now uses text captchas on page edits. Trusted editors will not see them. If you're not smart enough to answer the (extremely simple) questions, then you lose. (That's potentially a small problem on pages that say "ask your questions here", but really... the captcha questions are very simple.) I also removed all firewall-level IP blocks, for now at least.

This is a MoinMoin wiki. Language packages have been installed for German and Spanish (need to verify...?), but virtually all the content herein is in English. This wiki is running under twisted on port 8000, with an Apache reverse proxy pointing to it. Thus, you may reach it either via http://wooledge.org:8000/ (talking directly to twisted), or http://mywiki.wooledge.org/ (virtual host through Apache proxy).
