Hello Folks @ 3000-l

RE: FTP open command (FTP/iX's 50 Sin's /?;~)

Just a quick note for those folks who mentioned that FTP does not
time out on a bogus IP address:

  ftp 99.99.99.99

What I found was it actually was timing out, but after 10 iterations
of the configured TCP timers.

------------------------------------------------nmmgr default timers--
Path:  NETXPORT.GPROT.TCP

[4  ]     Retransmission Interval Lower Bound (Secs)
[180  ]   Maximum Time to Wait For Remote Response (Sec)
[5  ]     Initial Retransmission Interval (Secs)
[4  ]     Maximum Retransmissions per Packet
------------------------------------------------nmmgr default timers--

So in the example of the default TCP timers...

Initial SYN
5 seconds Retransmit SYN
10 seconds Retransmit SYN
20 seconds Retransmit SYN
40 seconds Retransmit SYN
===
75 seconds

and this sequence was performed 10 times for 750 seconds or 12 minutes
30 seconds and resulted in the 50 Sin's /?;~) (50 SYN packets sent out).

If your timers are configured different than the default, then YMWV.

This problem is identified as SR 8606231617.  I will post back to the
3000-l news group when the ftp client is repaired and patches are
available at the HP-RC.
