5289.0. "FTP hang, when connection was down" by DAIVC::ROSDIYANTO () Sun Mar 02 1997 22:57

Hello all,

I was installing UCX033 on VAX system, and I have a FTP problem when I connect
to remote Host.
The problem is like below :

In first time the connection to remote host is well. 
Then we FTP, open remote host, then login with username and password 
succesfully. Next we copy a file from remote to local host. The first file 
is succesfully copied. When we copy the second file,
the connection to remote host was down.

The problem,the process (copying second file) look like running,
doesn't have any error message, and this proccess take a long time and look
like hang. We waiting this process for long time until the connection is well,
but after the connection is OK, the proccess is still hang.

Would you like to give me an explanation when the connection was down,
why the procces was hang, not give an error message.
 or any UCX logical name that should be set ?

Thanks a lot for your help.

Regars,

    Please submit an IPMT for this case.  Be sure to include as much
    information as you can with it.  From what I have read, I don't see any
    messages, sample sessions, or traces that give me anything to go on
    except for your description of a connection problem.
5289.2command procedure that make hangDAIVC::ROSDIYANTOTue Mar 11 1997 02:3949
Hello,

This is the real problem that was happen :

We have a command procedure that we submit with batch process,
for copying some files from remote hosts (SUN Sparcstations).
The command procedure is :

$ FTP
  open httower1
  user user1
  user1
  mget mms*.mim
  mdel mms*.mim
  close
$ FTP
  open httower2
  user user1
  user1
  mget mms*.mim
  mdel mms*.mim
  close
  quit
$ exit

This batch was re submited every 5 minutes continuosly.  Remote hosts (SUNs) 
are connected via microwave and wireless bridge that some time have 
trouble that coused by weather.

This command procedure was hang, when :

1. login to remote host successful, then the connection was trouble. 
   So this batch is hang. 
   If we check with show que the batch status is executing. 

2. After login with user user1, but the password not yet come,
   than the connection was trouble.
   So this batch is hang too. 

3. After command mget mms*.mim, then the connection was trouble.
   And this batch is hang.

Could you help me to solve this problem.
Your suggestion is verry appreciated.

Thank a lot.

Best regards,
Ros

    Please re-read .1.
    
    Also, you are running UCX V3.3.  There have been numerous corrections
    and behavioral changes to FTP in recent releases.  I would upgrade to
    V4.1, latest ECO.
