Very interesting!  Thanks.  I guess I had ECN disabled, as
`cat /proc/sys/net/ipv4/tcp_ecn` outputs 0.  I tried 
`echo 1 > /proc/sys/net/ipv4/tcp_ecn` but it didn't help connecting.

This drew my attention to a bewildering array of networking options in 
/proc/sys/net/ipv4 but I don't know what else to try to tweak.  I'm 
running RedHat 7.3 and that interface is configured as:

eth0      Link encap:Ethernet  HWaddr 00:90:99:BD:5A:33  
          inet addr:219.3.154.33  Bcast:219.3.155.255  Mask:255.255.254.0
          UP BROADCAST NOTRAILERS RUNNING MULTICAST  MTU:1500  Metric:1

Any ideas?
