pure-ftpd

I running the command

Code:

/usr/sbin/pure-ftpd -l puredb:/etc/pure-ftpd/pureftpd.pdb -X -O clf:/var/log/pure-ftpd/transfer.log -A -u 1000 -p 40110:40115 -x -C 100 -P SOME.IP -8 UTF-8 -c 20 -E -B

But it still says my maxium allowed users are 3:

Code:

someone@somewhere:~$ ftp www
Connected to www.somewhere.com.
220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
220-You are user number 1 of 3 allowed.

FYI: I'm using Ubuntu 10.04.2 LTS

Any ideas?

Hi,

This is because you use -p to specify a range of ports. From pure-ftpd manpage:

Quote:

-p first:last
Use only ports in the range first to last inclusive for passive-mode downloads. This means that clients will not try to open connections to TCP ports outside the range first - last, which makes pure-ftpd more compatible with packet filters. Note that the maximum number of clients (specified with -c) is forced down to (last + 1 - first)/2 if it is greater, as the default is. (The syntax for the port range is, conveniently, the same as that of iptables).

In your case it's: (40115+1-40110)/2=3

Regards

Updated my port range so it should get 25 users, based on your maths. But still didn't work.

Code:

/usr/sbin/pure-ftpd -l puredb:/etc/pure-ftpd/pureftpd.pdb -X -O clf:/var/log/pure-ftpd/transfer.log -A -u 1000 -p 40110:40159 -x -C 100 -P SOME.IP -8 UTF-8 -c 100 -E -B

Code:

someone@somewhere:~$ ftp www
Connected to www.somewhere.com.
220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
220-You are user number 1 of 3 allowed.

Any other ideas?

It's not my maths. It's the way pure-ftpd is supposed to work when the number of clients (-c) is bigger that the number of available ports (-p)
Anyway, try to put -c before -p and see if works. Make sure you stop and the start the server again.

Bingo! Seems the ubuntu /etc/pure-ftpd/ doesn't take that into account.
