Machine: DS01-L, 2 NICs, DQ-disk (ATAPI), VMS 7.3-1, TCPIP 5.3-18 newly (fresh) installed; no eco's found in PROD SHOW HIST so my guess is NO ECO's installed (yet).
Both NICs set to 100Mb, full duplex, one of these in configured in VMS (so VMS sees just one). FTP service has bee enabled and is running.
Using FTP to set things up: NO problem at all getting files OFF the machine, but FTP GET eventually hangs the machine, the connection is lost at some point.
The same applies if the machine is accessed with FTP from antother machine. GET is no problem but PUT hangs the machine. I found even ^T does no longer work. So I crashed the machine (^P, then issued CRASH command)
The problem seems not related to the size of the transferred file.
We have a workaround, but still need to solve this.
What could have caused the problem and how to solve it (in reverse order, eventually. Solving is prime priority ;-))
If you need more information, I DO have this crashdump, so tell me what to do to get info out of it....

Re: URGENT: FTP problem
But another (VERY old: AXP2000) system, with 1 (100Mb?) NIC, same software environment so no patches, has NO problem at all. So my imprseeion is there's sometyhing wroong in the DS10L. Perhaps the second (not configured) NIC? (I did have problems (on another machine) with 2 NIC's)

Re: URGENT: FTP problem
This means that some module running kernel mode has caused error.
You could take aim better:
a)user connected is anonimous or is registered?
b)other user cause same problem?
c)in SYS$LOGIN of user, what do you read in log file TCPIP$FTP_SERVER.LOG?
d)what do read into SYS$SYSDEVICE:[TCPIP$FTP]?
Bye

Re: URGENT: FTP problem
1. User is registered
2. Other user has the same problem
just tried these on a TELNET session.
I tried to copy a relatively small file (login.com normally is not that big ;-)), it _seems_ this is copied. But larger files fail. Happyly, VMS is not crashing, just the process is disconnected.
I found (after logging in) that the file I want to copy is created. At least, DIR/SIZ-ALL shows it's name and sizes but the actual size is still zero. (I could stop FTP by ^C this time). 3. FTP log shows nothing. One I found had elapsed time of over 1 hour but less than a second used CPU....BTW. This was NOT the one on the login-directory.
Started a second session for monitoring, and re-ussued FTP command on the first one. MONITOR SYSTEM on the second session shows NO action at all, and after some time it's connection is lost.
Trying to login again does not work, all activity seems to be frozen, you cannot even login....

Re: URGENT: FTP problem
The problem may be specific to the ethernet card in the DS10. Your AS2000 does not have a problem because its a different card.
Installation of the patches makes sense - if you go to hp support with this then that's what they will say as they don't want to debug things already fixed in patches.
Purely Personal Opinion

Re: URGENT: FTP problem
It turned out that even DIR within FTP halts the process, diconnecting it after some time, and even a (new) TELNET session is freezing and disconnected after some time.
Furthermore, people that worked on preparing the machine told me outbound FTP did work previously, but since the sysmgr that setup the system is not available, I cannot tell what has been done ;-(. It seems they did something with NFS, and NFS_CLIENT was enabled. So I disabled it.
Next, I rebooted the machine.
I found that VMS keeps telling me the interface is SIMPLEX:
WE0: flags=c43
inet 10.100.51.250 netmask fffffe00 broadcast 10.100.51.255 ipmtu 1500
but in SRM it is set to 100Mb FD. In practice (on the switches) it is indeed.
Routing looks ok as well:
$ tcpip show route
DYNAMIC
Type Destination Gateway
AN 0.0.0.0 10.100.50.1
AN 10.100.50.0/23 10.100.51.250
AH 10.100.51.250 10.100.51.250
AH 127.0.0.1 127.0.0.1
First FTP I did, i started with DIR and here, data came in chunks - it looked as if the connection was stalled for a short while. Next GET (of a 380 block file) ran into timeout after some time (tens of minutes).

Re: URGENT: FTP problem
if we are talking a DEC 2000 (aka Jensen), the network speed will be 10 Mb, not 100 Mbit, so totatlly different drivers.
What NIC is in the DS10L? On-board or PCI card?
In case the system does not crash, do you see error counters on the device/tcpip?
Greetings, Martin

Re: URGENT: FTP problem
On board - it's just one inch thick ;-)
And indeed: the device shows ONE error. No matter how often I try to FTP. That should not be the problem since outgoing FTP and telnet etc are Ok. It's only when files are transferred TO that machine that's gving trouble - that is: larger then a few blocks (Login.com, about 5 blocks, went Ok). No matter whether it's GET (from the machine itself) or PUT (from another machine). I tyried both 10Mb and 100Mb counterparts. No difference :-(
Is this a hint: Those two NICs, of which just one is configured in VMS? As said, I had similar (even worse) problems with two DE500NICs in my own machine (TCPIP duidn't work well either)

Re: URGENT: FTP problem
My one DS10L is running 7.2 and we have not patched it in 2 years. (It's not broken!)
At a minimum, I would also install the PCSI and UPDATE patch.
Note: a Shadow set copy/merge of a 350GB LUN will also tank the DS10 and cause it to freeze. :-)
