LinuxQuestions.org - vsftpd + passive ports range connexion problem

Hi,

here is the thing: i had set up a ftp server with vsftpd on a Mandrake 10.1 and i am behind a router/firewall (Speedtouch 510v4). Everything's running fine, i can connect to the server without any problem. Here is my problem: from another computer/ip, i can connect (passive mode) the first time, the second time and let say that the third time vsftpd keeps wanting the client to connect on some ports that i didn't put in the conf file. From that time, i can no longer connect to the ftp server in passive mode cause it sends wrong ports (for example 10800, 10801, 10802....)

My router/firewall is forwarding the ports 40500 to 40519 and the port 21 the local machine.

here is my vsftpd.conf file:

Code:

anonymous_enable=NO

anon_upload_enable=NO

anon_mkdir_write_enable=NO

anon_other_write_enable=NO

anon_world_readable_only=YES



local_enable=YES

write_enable=YES

dirmessage_enable=YES



xferlog_enable=YES

ls_recurse_enable=NO



connect_from_port_20=YES



idle_session_timeout=600

data_connection_timeout=240

accept_timeout=60

connect_timeout=60



ascii_download_enable=NO



banner_file=/etc/banners/ftp.msg



chroot_local_user=YES

chroot_list_enable=YES

chroot_list_file=/etc/vsftpd.chroot_list



hide_ids=YES

pasv_enable=YES

pasv_promiscuous=YES

port_promiscuous=YES

pasv_max_port=40519

pasv_min_port=40500

i hope i was clear. So to sum up: i can connect (passive mode) to the server and it uses ports from 40508 to 40516. It lasts 5 minutes then without any reason the server sends passive ports from 10800 to 10815 and i can not connect (the number of the ports are just an example). Also I never had a successful connection with IE, Firefox...(IE gives me a 425...)

Any ideas ? i don't have anymore....:cry:

thx for help.
