Ar eyou're two systems in the same subnet? What is the route between the two systems (netstat -rnv).
You can always check the network setting of your system:
e.g.
#ndd /dev/hme link_status
1 ( link is UP )
# ndd /dev/hme link_speed
1 ( link speed is 100Mb )
# ndd /dev/hme link_mode
0 ( link is in half duplex mode )

# ndd /dev/hme link_mode
0 ( link is in half duplex mode )
Probably a silly question, but you have rebooted since changing /etc/system, right? Changes to that file only take affect at boot.
It could be an invisible problem like late collisions on the wire.
Does the switch have any snmp support ?
There you should be able to see the statistics
On the sun box, use an undocumented oprion to netstat
netstat -k it will dump every networking structure from the kernel
netstat -s gives you tcp statistics

Thanks for your help guys the problem was on my Cisco 4000 Switch the port was set to 100-Half duplex after set port (poort) duplex full and set port (port) speed 100
also i noticed crc's on my port afetr setting those every thing came back up OK.

Make sure the IP address of both machines are in the /etc/hosts file on each machine.
Are they on the same subnet?
Use netstat -i 5 to monitor network traffic while you are in the ftp session.
You could also use 'snoop' to keep an eye on the network traffic.
