ftp service problem

Kivanc KARACURA — Mon, 25 Jun 2007 05:28:20 GMT

i have an ftp problem on my vms 7.1 box.
when i check with
$ ucx show service ftp/full
the limit info is ;
Limit: 10 Active: 10 Peak: 10
when i disable / enable ftp service , active session begins to increase up to 10 and when it reaches to 10 ftp becomes unavailable.
i want to check the log file to find out what is causing this but when i try to read the log file UCX$FTPD.LOG;5044 under SYS$SYSDEVICE:[UCX$FTP] , it gives
$type UCX$FTPD.LOG
%TYPE-W-OPENIN, error opening SYS$SYSDEVICE:[UCX$FTP]UCX$FTPD.LOG;5044 as input
-RMS-E-FLK, file currently locked by another user
error. this is because the service is using the file , how can i cutoff this log file without stopping the service. i have tried disabling the service then opening it and it didn't work ... thanx in advance

Welcome to the Openvms forum

You should increase the service limit for FTP

ucx set service ftp/limit=200
for example, but then you will need to bump some quotas

What gives
$ ucx sh version ?
$ mc authorize sh ucx$ftp

A general way to look into a locked file is:

$ BACK/IGN=INTER file.log tmp.file
$ TYPE tmp.file

Hello

Bump tqelm, bytlm and pgflquota of the ucx$ftp account, and restart ftp, so

mc authorize mod ucx$ftp/tqelm=bigger/pgflquo=bigger/bytlm=bigger

begin with 5 times the values posted.

Then stop and start ftp (when it is not a problem for other people)

$ @sys$startup:ucx$ftp_shutdown
$ @sys$startup:ucx$ftp_startup

Apply the last Eco for Ucx ( I think it is Eco 5)

Volker Halle — Mon, 25 Jun 2007 06:06:51 GMT

You can use BACKUP/IGN=INTERLOCK SYS$SYSDEVICE:UCX$FTPD.LOG x.x
and then look at X.X

$ UCX SHO DEV /PORT=21 should also tell you, which session exist to the local FTP server.

Re: ftp service problem

Volker Halle — Mon, 25 Jun 2007 06:18:28 GMT

The FTP server seems to somehow have a problem with the FTP client requests from IP address xx.xx.xx.xx

try< to find out, what's running on that remote node and causing the FTP sessions to be quickly consumed.

You might need to stop the FTP server process before re-starting FTP.

$ SHOW SYS/PROC=*FTP*
$ STOP/ID=

Re: ftp service problem

Kivanc KARACURA — Mon, 25 Jun 2007 06:26:47 GMT

last time i have stopped ucx$ftpd by SYS$COMMON:[SYSMGR]UCX$FTPD_SHUTDOWN.COM and
restart it by submiting
SYS$COMMON:[SYSMGR]UCX$FTPD_STARTUP.COM

in this case the account that ftp'es and gets files couldn't get files resides in its home folder. vms gave "could not create socket" error.

If i stop the process by pid id , how can i restart it ? by SYS$COMMON:[SYSMGR]UCX$FTPD_STARTUP.COM ? or is there anyway different ?

Re: ftp service problem

labadie_1 — Mon, 25 Jun 2007 06:34:22 GMT

Yes you restart it by
$ @ SYS$COMMON:[SYSMGR]UCX$FTPD_STARTUP.COM
or using the menu
$ @sys$startup:ucx$config
and take the option
"start ucx" or a similar text

Re: ftp service problem

Volker Halle — Mon, 25 Jun 2007 06:35:50 GMT

Shutdown FTP using the UCX$FTPD_SHUTDOWN procedure. If the UCX$FTPD process does not disappear, use STOP/ID.

Then start FTP again using @SYS$STARTUP:UCX$FTPD_STARTUP

But be aware, that there seems to be some kind of problem with the FTP client application on that remote node.

$ show sys
Any processes in state beginning with RW ? (e.g. RWAST)

Wim

Re: ftp service problem

Kivanc KARACURA — Mon, 25 Jun 2007 07:02:00 GMT

no there is no process begining with RW.

a collegue of mine suggested to
SET EXECUTOR MAXIMUM LINKS 48

does this work ?
if so , at which promt should i run this command ?

Re: ftp service problem

Volker Halle — Mon, 25 Jun 2007 07:04:36 GMT

NCP SET EXE MAX LINKS xxx is a DECnet configuration command. This problem is with TCPIP (UCX) and has nothing to do with DECnet.

Re: ftp service problem

Kivanc KARACURA — Mon, 25 Jun 2007 07:14:11 GMT

additionally , we have encountered ftp problem before and stopped / started ftp by

$SYS$COMMON:[SYSMGR]UCX$FTPD_SHUTDOWN.COM
$submit SYS$STARTUP:UCX$FTPD_STARTUP.COM

after this there was no process named UCX$FTPD , in place there was BATCH_78.
I think ftp service was running in a different manner and the account XXX could connect but that's all , it couldn't do anything even dir. you can see the process below.

331 Username XXX requires a Password
Password:
230 User logged in.
ftp> dir
200 PORT command successful.
425-Cannot create data socket.
425 insufficient privilege or object protection violation

what can be the problem ?
If i stop/start ftp by the same way again , probably the same thing would occur.

Re: ftp service problem

Volker Halle — Mon, 25 Jun 2007 07:21:18 GMT

Sorry, UCX$FTPD_STARTUP.COM is the FTP service start procedure, which runs the FTP service daemon and it's not meant to be called to start FTP.

The procedure to start/stop FTP should be xxx$FTP_STARTUP.COM or xxx$FTP_SHUTDOWN.COM, but that file doesn't seem to exist on this old UCX V4.2 version.

Stop that batch process and try UCX ENA SERVICE FTP.

Volker.

Re: ftp service problem

labadie_1 — Mon, 25 Jun 2007 07:21:20 GMT

You should not use submit, but just @, and more important, from the SYSTEM account.

Re: ftp service problem

Kivanc KARACURA — Mon, 25 Jun 2007 07:33:46 GMT

Volker ,
I didn't run startup.com , this was the recent process.
for most recent problem
SYS$STARTUP:UCX$FTPD_SHUTDOWN.COM was worked and ftp deamon was killed.

SYS$STARTUP:UCX$FTPD_STARTUP.COM didn't work , after command i dropped
to $ promp without any error message but i couldn't see ftp deamon in sh
sys ...

after that i have run
submit SYS$STARTUP:UCX$FTPD_STARTUP.COM

then ftp service has started as batch job but as i mentioned ; while trying to ftp files vms gave error.

labadie ;
how can i run it by @ under system account ? should i login by SYSTEM or is there any parameter that i can use without knowing the password of SYSTEM

Re: ftp service problem

Volker Halle — Mon, 25 Jun 2007 07:46:43 GMT

If you look at UCX SHOW SERV/FULL FTP, you will see, that SYS$SYSDEVICE:[UCX$FTP]UCX$FTPD_STARTUP.COM is the file, which is run by the FTP service, if a session connects to port 21. It is NOT a command procedure to start the FTP service.

Try to start the FTP service by:

$ UCX ENABLE SERVICE FTP

You don't have to do this under SYSTEM. UCX V4.2 does not seem to have a separate DCL procedure to start the FTP service.

Volker.
