FreeBSD wiki offline for a bit

[Simon L. B. Nielsen]

Hey,

tl;dr Wiki is back, and everybody with account need to reset their password.

The wiki is back now.

Looking at logs it there were people attempting to exploit this back
in July but I do not think they actually succeeded. It seemed to
mostly automated bot and not a target attempt.

The wiki has been reinstalled from scratch and users and pages were
copied. As I did a very selective copy it's entirely possible I made
the wiki unhappy, so let me know if you see issues.

Just to be extra safe I have reset all password, so everybody will
need need to use the standard account recovery process to set a new
password.

On a side note we have ~23000 user accounts and had 26000 empty pages
mostly caused by spammers, so someone(tm) will likely need to find a
way to change how we handle wiki user accounts to fix this.

PS. only reason I could see that they tried back in July was that I
found out I had forgotten to set up log rotation, so the wiki logfile
was over 3GB :-). (It was the internal log file which doesn't contain
user IP's so privacy part isn't really an issue.)
