My Question is:
I'm experiencing the same problem as another enquirer as below
however my settings are as you already recommend.
I can ftp to an older VAX with no problem.
The problem exists between two alpha servers of the same specification.
550-Network READ failure.
550 connect to network object timed-out or failed

Previous Question by another enquirer was:
Hello,
Every time we make an ftp between two VAX of large files (> 100 Mb) we have
this error message which appears
550-Network READ failure.
550 connect to network object timed-out golden failed
We have no problem for the small files and the transfer takes place well. We
have no network problem and we can make a transfer of large files between 2
machines NT.
Please, could you please check may cause the problem.
Cordially.

--------------------------------------------------------------------------------
The Answer is :
This could be a known interaction between TCP/IP V5.1 ECO 4 and a
unitary MTU setting that is occasionally found after upgrades from
older IP releases.
Intervening firewalls can also potentially be involved.
If tcp_mssdflt is set to 1, consider resetting it to the typical 536.
After having invoked the following:
@sys$startup:tcpip$define_commands.com
Use the following to display the current tcp_mssdflt value:
sysconfig -q inet tcp_mssdflt
And -- if set otherwise -- use the following to reset the value:
sysconfig -r inet tcp_mssdflt=536

The Answer is : The referenced topic is (8215). You do not have the version referenced in (8215), as you have an older ECO kit loaded. Please ensure you have the current TCP/IP Services version and the current ECO loaded -- you are presently running an older TCP/IP Services version -- and please then contact the support center for assistance should the problem persist. As of this writing, TCP/IP Services V5.3 -- with ECO -- is current.
