[Bug] Bundling 2 NICs (data device traffic balancing)

[darko]

Hi,

i have 2 "lines":
1 x 10mbit directly connected to the internet - 129.x.x.1
1 x 10mbit with a router between internet and pc (NAT) - 192.168.1.3 / 129.x.x.2

i want to bundle both lines (=20mbit )

this is my ioftpd.ini (important parts only):

[V1]
Host = 0.0.0.0
Ports = 63487-65535
Random = True

[V2]
Host = 129.x.x.2
Ports = 63487-65535
Random = True
Bind = 192.168.1.3

[FTP_Service]
Type = FTP
Device_Name = V1
Port = 6969
Description = My FTP Service
User_Limit = 20
Allowed_Users = *
Messages = ..\text\ftp

Data_Devices = V1 V2
Random_Devices = True


i doesnt really work as it should tho. PASV/LIST on 129.x.x.2 takes about 4 secs (129.x.x.1 lists without wait), and sometimes theres even errors:

[R] (21:30:29) PASV
[R] (21:30:29) 227 Entering Passive Mode (129,x,x,2,251,11)
[R] (21:30:29) Opening data connection IP: 129.x.x.2
PORT: 64267
[R] (21:30:50) Listening at IP: 10.0.0.152 PORT: 2967 for data connecting
[R] (21:30:50) PORT 10,0,0,152,11,151
[R] (21:30:50) 200 PORT command successful.
[R] (21:30:51) LIST
[R] (21:30:51) 150 Opening ASCII mode data connection for directory listing.
[R] (21:31:21) DEBUG: Cant Open Data Connection
[R] (21:31:22) 426 Connection closed: Connection timed out.

(10.0.0.152 is NAT ip from where i login)

ports specified in ioFTPD.ini are opened and forwarded in router (an U.S. Robotics Broadband Router (Model # 8003 , 1.04 08 ) )

i even tried with DMZ: same problem

with 1 line 129.x.x.1 or 129.x.x.2 in ioFTPD.ini it works just fine but with 2 i get above problems. I tried everything i could think of but nothing seems to solve the problem. Anyone can help please?

can you post important parts from ioFTPD.ini plz?

[darko]

anyone?

Try:

[V1]
Host = 192.x.x.1
Ports = 63487-65535
Random = True

When you define a device for a specific network card, it's always a good idea to make sure it uses only this network card.
0.0.0.0 means "all NICs", and since the two devices are supposed to use the same ports for passive mode (according to what you've pasted), using it could lead to some conflicts between the two devices.
Let me know if it helps.

already tried that:

[V1]
Host   			 	= 129.x.x.1
Ports   			= 63487-65535
Random  			= True
Bind				= 129.x.x.1

[V2]
Host				= 129.x.x.2
Ports   			= 63487-65535
Random  			= True
Bind				= 192.168.1.3

any other suggestions?

i had the same problem when used to use wxp sp2 firewall. disabled and use kerio now and its much better, but not perfect. the delays still sometimes occurr.

[darko]

delays i could live with, list errors certainly not

*bump*

try'd specifing different port ranges for 129.x.x.1 and 129.x.x.2, didnt help either

[edit]
guys im starting to think this is an ioftpd bug rather than me doing something wrong or something else... i tried with fresh ioftpd install (ioFTPD-beta5-8-0r.zip & ioFTPD-beta5-8-5r-executable-only.zip) only changed the following in ioFTPD.ini:

[V1]
Host   			 	= 129.x.x.1
Ports   			= 63487-65535
Random  			= True

[V2]
Host				= 129.x.x.2
Ports   			= 61439-63486
Random  			= True
Bind				= 192.168.1.3

and under [FTP_Service]:

Device_Name             = V1
Port                    = 6969

### Traffic Balancing ###
#
Data_Devices            = V1 V2
Random_Devices          = True

in Host.Rules:

POLICY	ACCEPT	2

in admin.vfs:

"c:\TEMP\ioFTPD\site"        /

Logged into 129.x.x.1 and refreshed dirlisting few times (PASV, PASV, PASV etc etc ). logged in 2nd time and did the same. after 10-20x PASV it just "hangs" with a list error (see earlier post above). Also PASV on 129.x.x.2 always takes longer than on .1 (4 secs).

I tryed with several routers (Linksys, US Robotics) and i disabled all firewalls (software and hardware)/antivirus sw ... still the same. I'm really starting to think this is an ioFTPD thing...!

further info:
Windows 2000 SP4
3COM Etherlink XL 10/100 PCI NIC (3C905-TX) <- NAT
ND010 Ethernet/Fast Ethernet PCI Bus adaptor


please advice! darkone maybe?
