Subject: How many users??

How far have people pushed wu-ftpd (how many concurrent
users) ??  How many users could it  theoretically support
concurrently ??

I'm trying to get a feel for how far I can push it.

Dunno about the theoretical limits, but ftp.cdrom.com has a 1250 user 
limit last time I checked (which is usually maxed out, BTW).  They claim 
that they're using a single Pentium Pro 150 with a half gig of RAM; I 
suppose it's possible that such a box could handle that many users.

By contrast, we have an old-ish 133MHz Alpha here at wuarchive, with 192MB
of RAM, and our load avg. never drops below about 20 (50 is average) with
200 ftp users.  

I think that there's not much of a practical limit as long as you have 
sufficient CPU and I/O to handle it.

I may have misunderstood what "noretrieve" does, but it seems to work 
incorrectly in 2.4.2beta11... If I put the following line in my ftpaccess 
file:

noretrieve /etc/passwd

Then, when I do an anonymous login, I can't get the file, as expected.  
I.e., the following fails:

ftp> get /etc/passwd
local: /etc/passwd: Permission denied

However-- the following commands *do* work!

ftp> cd /etc
250 CWD command successful
ftp> get passwd
200 PORT command successful
150 Opening ASCII mode data connection for passwd... blah blah...
...etc...

Is this correct?  I know I could put "noretrieve passwd" instead, but 
that would prevent access to *all* files named passwd, which I don't want 
to do.  (I don't want to explain to some anonymous user why they can't 
up/download a file called "passwd", while everything else is ok...)

Comments?

Also-- (sorry for tacking this one on)  I've been struggling with the 
"upload" clause in ftpaccess.  I've entered these lines (and hupped, of 
course):

upload /opt/anonftp  *       no
upload /opt/anonftp  /pub/*  yes  ftp anonftp  0666

My goal is to let anyone upload anything into any subdirectory under 
/pub, but not to let any files get uploaded into /pub (keep clutter 
down...)  However, I *can* upload files to /pub as anon.  Also, all 
files and directories have mode 0664, instead of 0666...  What have I 
screwed up?
