Ethernet bonding mode 5 only using one Slave adapter.

[Muhammad Yousuf Khan <sirtcp@gmail.com>]

i am using bond mode balance-alb. and here is my "/etc/network/interfaces" file
##############################
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
        address 10.X.X.221
        netmask 255.255.255.0


auto bond0

iface bond0 inet static
address 10.5.X.200
netmask 255.255.255.0
newtork 10.5.x.0
gateway 10.5.x.9
slaves eth2 eth3
#bond-mode active-backup
bond-mode balance-alb
bond-miimon 100
bond-downdelay 200

same setting is on other end.

and the problem is only active link is transmitting and on the other node active link is receiving. no load balancing is performent i am using "scp" to transfer 1 5 gb file from two ssh session at the same time but both sessions are only using one network card. which is active in /proc/net/bonding/bond0 . here is the output.

note : as you can see in /proc/net/bonding/bond0 file the active link is eth2 and the bwm-ng showing transmission is also on eth2. even i use two session i thought it could work like round robin as in "mode 0" but both sessions are transmitting data from eth2.

what i want to achive is per packet load balancing. if i send two packets it moves out from both link eth2 and eth3. so i can combine 4x1 LAN card and achieve 4 GB of transmit rate and redundancy.

i know 4 GB network output achievement depends upon the hardware quality. i will check on that too. but at least bwm-ng could show me packet activity on all the links not only active link.

any help would be highly appreciated.

Thanks .
