ftpd patch that saves me a lot of hassle

2002-01-19 Thread Aaron Smith
I got sick of (presumably) warez people probing my anonymous ftp site and dropping all kinds of hard-to-delete trash in incoming, so I patched my ftpd to only allow directories to start with alphanumerics. There's probably a better solution, but this works for me so I figure'd I'd share.

gzip's custom i386 asm should be disabled

2001-03-20 Thread Aaron Smith
gzip's i386 assembly code, activated by default in the FreeBSD source tree, produces poor performance on an i686 core (PPro/P2/P3). This is due to the 'partial register stall' problem, explained in a URL recently brought up on the list, http://www.emulators.com/pentium4.htm. In the course of
