For those of you who posted having problems on Solaris 2.5
getting anonymous to be able to run ls -al (eg.), my friend
Thom White showed me the way to a script found at the end of 
the ftpd man page.  It fixed this problems.

For those of you who choose to work cautiously, it wouldn't hurt
to tar up your existing ~ftp dir.

Good luck.
And thanks Thom!
