Bug 328757 – net-ftp/pure-ftpd-1.0.29 ignores userlimit

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Conrad Kostecki 2010-07-17 20:32:15 UTC]

Hi!
I've installed net-ftp/pure-ftpd-1.0.29. But there seems to be a problem. The whole ftp server works fine. But the userlimit seems to be ignored.

Pegasus / # cat /etc/conf.d/pure-ftpd  |grep MAX_CONN
MAX_CONN="-c 100"
MAX_CONN_IP="-C 10"

But if I connect now, the server reports only:
[R] 220-Sie sind Benutzer 1 von 5 erlaubten.
(This means in englisch, you are number 1 of 5 allowed)

It doesn't matther which setting i use. It seems like it would be hardcoded.

Pegasus / # emerge --info

I cannot reproduce this behaviour. Can you please attach your 

  /etc/conf.d/pure-ftpd 

file to this bug?

Sure, here we go.

This is caused by the following setting from your config:

  -p 13380:13389

This permits pure-ftpd to only use _ten_ ports for clients. As each connection requires two ports you can only have five clients at the same time.
This is also described in the man page for the -p switch:

  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.
