FTP fouten en de firewall

[Glenn]

Dag,

Regelmatig heb ik fouten met het uploaden naar mijn server. Ik krijg dan de foutmelding:

! Receive error: Blocking call cancelled

.

Als server gebruik Ocean FTP Server (draait onder Win2003). Om te uploaden gebruik ik WS_FTP LE maar ook met andere programma's heb ik er last van. Dacht eerst dat het aan de PASV mode lag maar dat maakt geen enkel verschil. Mailtje dus gestuurd naar de ontwikkelaar van Ocean FTP Server, krijg ik dit terug:

These are all data connection problems.



FTP uses a normal command channel (21 or 990 for implicit SSL) then a separate port in the default range of 1024-5000 for data channels; the data channels not being established due to firewall / router setup problems is the most common FTP problem we see.

You need to allow ports 21, 990 (SSL) and 1024 - 5000 through your server firewall and forwarded from your router to your server and also enter the router IP in the FTP server general settings. Finally, if your FTP client is behind a firewall you need to use PASV mode on your client as you already are doing.

Port 21 staat inderdaad open, SSL gebruik ik niet, maar moet ik nu echt port 1024-5000 openzetten??? Als dat zo is, dan ben ik zuur, want in Windows Firewall kan je maar 1 port per keer opgeven of ik kijk ergens overheen.

Kan iemand mij uit de brand helpen?

die extra porten zijn naar mijn idee voor passive mode.

Weird, net weer geprobeerd, nu heb ik nergens last van bij het uploaden van files. Als ik echter nu een dir aanmaak (MKDIR), krijg ik deze error:

! Receive error: connection reset

Dit is zowel met PASV aan en uit.

Staan verder alle rechten goed?

Jep!
Ocean FTP Server is een service die je kan zien in Services.msc. De Ocean Service stopt echter na het maken van zo'n dir.

Ik post wel heel even de hele mailconversatie:

Dear Sir/Madam,

I'm using Ocean FTP for a couple of months. Today I've some problems with the FTP server.

Problem 1:
When I upload one single file I get this error at the end (it's bold):

After that message, de connection is AGAIN lost and the Ocean FTP service is stopped as I can see in the Services console.

Problem 3:
When I'll try to upload several files in just 1 'click' I get after the first uploaded file the same error als problem 3. Then connection lost and the service stopped.

My configuration:
Windows Server 2003 SP1 Standard Edition
Ocean FTP Version 1.1.6.0
Intel Pentium 4 2,4 Ghz
1024 MB RAM

Can you please help me with this problem?

Thanks in advance.

Misschien dat het probleem nu wat duidelijker is.

Meschien dat je dit alreeds hebt gedaan maar post het maar even voor de zekerheid.


Troubleshooting WS_FTP:
Blocking Call Cancelled Error
This error is peculiar to WS_FTP, and generally indicates a problem with a router (sometimes referred to as a "blackhole router") between your computer and and our network. There are 3 possible solutions:

Use CuteFTP or some other FTP client instead of WS_FTP.

In your WS_FTP configuration, change the setting for Passive Transfers (If you find that Passive Transfers is enabled, you should disable it and if it is disabled, you should enable it.) and/or

Increase the Network Timeout setting in WS_FTP to 120 or higher.

Vooral punt3 kan intressant zijn.

Nog een


I've been using WS FTP for a few years. I recently starting getting an error while trying to connect to certain sites. Others I connect to fine. The message I get upon trying to connect is "Receive error: Blocking call cancelled". I saw something about setting MTU to fix this. If this is the solution, and if so how do I do it? Thanks!

maar het is raar dat de gehele service er mee stopt ?

wat zeggen de log files van de ocean ftp server?

[Glenn]

Nou, dat is het denk ik niet, aangezien LeechFTP het ook heeft. Check:

< 226 Transfer complete.
> mkdir hallo
! Socket Error: connection reset by peer 
~ Disconnected

En vervolgens is mn FTP service weer gestopt! Het ligt dus echt aan de server!

[_arno_]

Daarom wil ik ook de log files van je server zien , niet van je ftp client.

[Glenn]

Ik heb accountlogs, ftplogs en servicelogs (van Windows):

ACCOUNT:

Wed, 11 Jan 2006 15:55:21 -> IP -> Directory Viewed: Directory=[/D]
Wed, 11 Jan 2006 15:55:23 -> IP -> Directory Viewed: Directory=[/D/www]
Wed, 11 Jan 2006 15:55:28 -> IP -> Directory Viewed: Directory=[/D/__temp]

(Meer staat er niet, aangezien het ik inderdaad in de map /__temp een nieuwe map aan wilde maken).

FTP-LOG:

Wed, 11 Jan 2006 15:55:21 -> IP -> administrator -> Directory Viewed: Directory=[/D]
Wed, 11 Jan 2006 15:55:23 -> IP -> administrator -> Directory Viewed: Directory=[/D/www]
Wed, 11 Jan 2006 15:55:28 -> IP -> administrator -> Directory Viewed: Directory=[/D/__temp]

Hetzelfde dus!

SERVICE LOG

The Ocean FTP Server service terminated unexpectedly.  It has done this 1 time(s).  The following corrective action will be taken in 0 milliseconds: Restart the service.

Die restart heb ik ingesteld.

Als deze gerestart is krijg ik dit in de service log:

A service process other than the one launched by the Service Control Manager connected when starting the Ocean FTP Server service.  The Service Control Manager launched process 4464 and process 4856 connected instead.

  Note that if this service is configured to start under a debugger, this behavior is expected.

Strange?

Dat was een reactie op SystemZ, m'n bovenbuurman in rack 25

Er valt weinig te configgen aan een ftp server wat betreft general settings

Ik ga nog eens een reinstall doen.
