Title: read error = NT_STATUS_END_OF_FILE
Post by: michelandre on June 14, 2015, 04:05:03 PM: Hi all,

192.168.1.7 - Windows 7
192.168.1.129 - Windows XP
192.168.1.81 - Windows 8.1
All in the same workgroup

I have a persistent problem. I have those messages repeating every 4-5 minutes:

The problem started in SME-8/32. I backup, get a new machine, installed SME-9/64, update and restore.
Same problem.

Small problem after restoration:
2 users were not able to log to webmail. I changed passwords and it was OK after.

I looked all over the web and found nothing to resolve that issue for those messages.

Any help appreciated,

Michel-André

In my original SME-8, I had "smeserver-remoteuseraccess" so I installed it on the new SME-9; nothing changed...

Any help will be very appreciated,

Post by: Daniel B. on June 16, 2015, 09:13:37 AM: I'd first suspect a network problem. Have you checked your cable and switches ? Also look in /var/log/messages if you have any message regarding your network cards
Title: Re: read error = NT_STATUS_END_OF_FILE
Post by: michelandre on June 16, 2015, 05:10:57 PM: Hi all,

Thank you Daniel for your hint.

I apologize for this long file.

Yesterday:
- I made a new backup of the old SME 8
- Re-installed SME 9 on the new server
- Updated SME 9
- Restored the new backup to SME 9
- Re-installed "smeserver-remoteuseraccess" and "Awstats"
- Did the same "FILENAME: 11loglevel_MAR_2015-06-15" for smb.conf
*** Exactly the same problem

Another problem:
The server is a Compaq D5850M/AP96 with 8 GB RAM
- When I install a new SME 9, the server boot OK
- After I update SME 9, the first lines on the boot says:

Originally, after installation the screen is 1600x900.
After update the screen look like a standard DOS, around 800x600
I looked for the file "radeon/R600_rlc.bin" and it is not in the system. I found one on Internet but I don't know if it is safe to install.
I saw a video rompaq file for Linux from HP but it requires gcc and X that SME don't have.
I updated the BIOS to the latest version and restore the default settings.

Is this a SME bug?

******************************************************

Today after reading Daniel post:
- changed the ADSL modem for another one
- Changed the connecting switch
- changed all cables
*** Exactly the same problem

Today plan:
Wait a few hours for any hint from the forum just in case the following scenario is not possible and there is a better one
- Create a virtal machine with VirtualBox
- Install SM 9 with same name-1, domain-1 as original SME 8
- Update SME 9
- Create all the same: users, i-bays, domain name etc... on the VM
- Tar the users folders, all i-bays, awstats folders on original; backup the 3 DBs of MySql for my 3 web sites on SME-8. The tar will preserve properties
- Disconnect SME 8
- Rename SME 9 ti the same name and same primary domain as on SME 8
- Extract in their same folders for the TARs with "--same-owner" to preserver owners in SME 9
- Restore the 3 DBs of MySql
- Hoping for the best...

Questions:
- Is it OK to tar and restore the users folder as the users will have the same name but won't have the same UID in the new SME 9 VM?
- Is there another way to restore only the users; mainly for the emails?
- I have the same problem "read error = NT_STATUS_END_OF_FILE" on SME 8 and now on SME 9 on different hardware. I think it is related to something in SME?

For the i-bay, they all use WordPress and all have XCloner so I can use it for the backup and restore for the content of the i-bay and MySQL DBs.

- I have quite some traffic on my main web site and sometime when I browse the web, I have to wait some time for the a web page or google to appear. Sometime I receive a invalid address and the led on the switch is flashing quite a bit and I presume it is because of the traffic, the leds on the switch is blinking for the ADSL and the server. I refresh a couple of times and the page is received.
- Also, it seems like there is a lot of broadcasts because all the leds on the switch blink every two three seconds.
*** Question: Is this in relation with my problem?

I am thinking of going to 15Mb VDSL.

Any help will be very very appreciated,

Michel-André

Title: Re: read error = NT_STATUS_END_OF_FILE
Post by: michelandre on June 18, 2015, 06:05:46 AM: Hi all,

Some developments.

I really think this is a bug in SME 9 and also in SME 8 at least since the middle of April 2015.

I create a new machine not a VM.

MAIN SME: (My main SME with the problem NT_STATUS_END_OF_FILE)
Name: dorgee
Domain: micronator.org
Local IP: 192.168.1.1/255.255.255.0 connected to SWITCH-A
External IP: static from ISP

WORKSTATION:
Windows-8.1
IP: 192.168.1.81/255.255.255.0
Remote backup folder for SME: Sauvegarde
Backup user: toto/password

NEW MACHINE:
1) I connect the LOCAL card to SWITCH-B so SME 9 will think that it is connected to a real network. Nothing else is connected to SWITCH-B.
2) I connect the EXTERNAL card to my network SWITCH-A so I can update after installation.
3) I install SME 9:
- Name: dorgee-1
- Domain: micronator-1.org
- LOCAL: 10.10.100.38
- Server & Gateway
- EXTERNAL: receiving IP (192.168.1.189) by DHCP from my main SME 9 (dorgee.micronator.org) through SWITCH-A
3) I update SME 9
4) I install lynx to be able to navigate on the server console in Server-Manager
- I allow Networks: 192.168.1.0/255.255.255.0 and 10.10.100.0/255.255.255.0 to access remote Server-Manager.
5) I configure remote backup to Windows-81.

RECONFIGURATION OF NEW SME:
6) I stop the new server
7) I connect LOCAL to WORKSTATION (Nothing else is connected to the WORKSTATION; WiFi is off)
8- I connect EXTERNAL to SWITCH-B so SME 9 will think that it is connected to a real network. Nothing else is connected to SWITCH-B.
9) Power on new SME.
10) RECONFIGURE same as original MAIN SME (because I want to restore from remote backup)
- Name: dorgee
- Domain: micronator.org
- LOCAL: IP: 192.168.1.1/255.255.255.0 (connected directly to WORKSTATION)
- Server & Gateway
- EXTERNAL: PPPoE (connected to SWITCH-B, it will try to connect to ISP... forever...)

11) Now I am ready to restore.

12) Before I restore, I check the log messages.

TOTAL HORROR THE FAULT IS THERE ALSO

Impossible, there is something wrong with the Windows-8.1 Wokstation

13) I replace the Workstation with a portable WindowsPro-7
13) I give a static IP to WindowsPro-7: 192.168.1.66/255.255.255.0
- Create a shared folder: Sauvegarde
15) Connect to the new SME 9.

AGAIN: TOTAL HORROR THE FAULT IS THERE ALSO

Now, I really think this is a bug in SME

- Is it because I changed the name and domain?
The name and domain of my original SME 8 was never changed
- I never had this problem before.
- The only thing new in my network is a new Windows-8.1 since April 20th 2015.
- I updated: 8/3, 10/4.
- I noticed it at the end of April 2015.

I hope I am wrong but I have doubts...

I just noticed that the message ...NT_STATUS_END_OF_FILE is exactly every 10:00 minutes.

Maybe unrelated, but sysstat has a cron job that runs every 10 minutes....
Title: Re: read error = NT_STATUS_END_OF_FILE
Post by: michelandre on June 20, 2015, 05:25:27 AM: Hi all,

Thank you RequestedDeletion for your comment.
I looked at cron log from Server-Manager and found nothing that runs every 10 minutes.
Can you explain a little what you mean by sysstat.

- Backup the original SME 9 to remote Windows-8.1 desktop
- I tried a new hardware. Nothing was tied to this machine except the two network card hooked up to a stand alone switch.
- Installed from CD
- Same domain as original server.
- Server name as original but with "-1" appended to it.
- The rest of the config is the same as the original SME 9; Server & Gateway, PPPoE, etc...

I used server console (su - admin) to look at the messages log. No error.
- I do not update just in case the error was from the update.

I kooked up the Windows-8.1 to restore the backup.
- All went fine.
- Again, I used server console to look at the messages log, no error; I waited 25 minutes to make sure there will be none.

I though I had it made. I connected the new machine in place of the original SME 9.
Right away the error appeared...

** Maybe it is something on my network...
I connect the Windows-8.1 card directly to the local card of the server to elimate all my network.
Error appeared...

This error appeared since I changed SME-8/32 to SME-9/64.
This user remote logins to webmail.
Every day the login fails and I have to change his password and it works for a few times then again fails.
Is that related to my problem or vice versa?

Post by: michelandre on June 24, 2015, 05:51:17 PM: Hi all,

Now I am investigating what can cause Win-8/7 to use FTP to connect every 10 minutes to the SME Server: Email, Workgroup, shared folder, NTP ???

I closed my mail (Thunderbird), I changed the workgroup for the Sations to be different from the workgroup of the server, the stations use NTP from the Internet... what else can I check ???

Post by: Stefano on June 24, 2015, 06:12:54 PM: SME in server & gateway mode?
is there anything in proftpd logs?

to make a test, shutdown/disconnet (phisically) all clients from LAN but one..
on this client, shutdown one software/service at once..

I see there are many clients so, not only one.. think about a sw running on the clients.. AV, $whatever..

keep us informed and good luck

Win-7 is disconnected.

Couple of days ago, I deeply scanned for virus and rootkit both stations 2 times.

I have a HP printer connected to Win-8 and it is shared.

- One test I did was to build a brand new SME-9, only Win-8 connected, no update to SME-9, wait 25 minutes and all was OK. As soon as I connect to the ADSL the problem came back.
- After this post, I will disconnect the ADSL from the telephone line and see what will happen...

Any help will be very very very very very appreciated,

Title: Re: read error = NT_STATUS_END_OF_FILE
Post by: michelandre on June 24, 2015, 07:10:01 PM: Merci Daniel pour ta réponse.

Now, I have only Win-8 at 192.168.1.81 connected to the switch.

I disconnected the ADSL from the phone line. Still the error.

Now I will take the switch out, connect the server external connection directly to the ADSL and Win-8 directly to the local connection of the server and see what will happen.

Results back in a few minutes.

I don't think is a evil sw acting so.. IMHO it's likely a windoze c**p agent/sw..

I'd install sysinternal's tool suit on a client and debug lan traffic.. there's a tool (I don't remember tha name, sorry) that can display which software/process is accessing the network interface..

again, good luck.. "windows, how do you want to get crazy today?" (Cit.)

Post by: michelandre on June 24, 2015, 11:35:10 PM: Thank you Stefano for you comment.

I have only the ADSL and Win-8 and the problem is still there. So maybe it is Win-8 causing the problem.

I have a Win-XP, Win-7 and Win-8. They all have the same problem.
If I connect a portable with Win-7, I have the same problem.
The only things they have in common is Avast and Spybot and the SME Server.

I have an old Win-7 Virtual Machine (VirtualBox) on my Win-7 Station that I did not touch since a long time. I started it and same problem. I uninstalled Avast & Spybot, reboot and still the problem. I tried with and without getting the address with DHCP and still the problem is on the old machine. It was not there before...

There is a law in the technical world: "You can not have the exact same problem on two different machines at the same time.."
In all my years of technical work, this law never prooved wrong...

I do not know what else I can do...

Any help will be very very very very very very appreciated,

Michel-André

I have a persistent problem. I have those messages repeating every 4-5 minutes:

Is your only problem that you see log messages (every 10:00 minutes)?
Title: Re: read error = NT_STATUS_END_OF_FILE
Post by: michelandre on June 25, 2015, 10:31:53 PM: Hi all,

Thank you RequestedDeletion for your suggestions.
I checked all the config for all the cards on Win-7 & Win-8.1; all the virtual cards also. I took out all the the IP-v6. Same problem.

Hi CharlieBrady,

- I had another problem. One user was loging on Webmail from remote. He was OK for one or two logins then impossible to login again. I had to change his password then it was OK for one or two times and again impossible to login.
- Finally yesterday I tar his Maildir. Delete user. Wait a few minutes. Recreate exactly the same user with the same password. I untar back his Maildir, changed the owner and group to his own name.
- He connected 4-5 times today and so far so good.

When I first restored the backup from SME-8 to SME-9, in Thunderbird (on Win-8.1) I had an account that it was not possible to login to the server. All my other 5 accounts from the server were OK. I deleted the faulty account in Thunderbird, recreate the exact same account in Thunderbird and all was OK after that.

Beside that, when I am googling, it is taking quite some time to get the page. Sometime it was "Page not found", refresh and it was OK. Also it was taking 4-5 seconds before I see in the left bottom line of Firefox that is was looking for the URL.

Three days ago, I decided to change from ADSL to VDSL.

- I noticed since 2-3 days that the ADSL is loosing the line every 2-3 hours and sometime every 10-15 minutes.
- Yesterday, I phoned Teksavvy support to ask them to check my line but since I am in the process of going to VDSL, it is the "nice good Bell" that is controlling my line in the interim and Teksavvy cannot check it for now. I have to wait until July 8th for the switch. Until then, I think there is no time to loose talking to "nice good Bell"...
- The technician suggested I change the ADSL for the new VDSL modem. I did that last night. Loosing the line is always there but it seems googling is better.

This morning I changed all the cables for CAT-6, just in case...

Any help will be very very very very very very very appreciated,

Michel-André

Just a question: what is that "smbd/process.c" in the log messages?

I can not find a file "process.c" on the server or on the station...

Thank you for any suggestions,

Post by: michelandre on June 29, 2015, 10:14:26 PM: Hi all,

I installed Wireshark on Win-81 to check the communication.

- Power off Win-81
- Reboot server
- Power on Win-81
- Sync the time of Win-81 with the same NTP server as SME-9
- Running only Wireshark on Win-81

From messages log:
Jun 29 14:56:20 dorgee proftpd[2378]: 192.168.1.1 (192.168.1.81[192.168.1.81]) - FTP session opened.
Jun 29 14:56:20 dorgee proftpd[2378]: 192.168.1.1 (192.168.1.81[192.168.1.81]) - FTP session closed.
Jun 29 14:56:28 dorgee smbd[2382]: [2015/06/29 14:56:28.824473, 0] smbd/process.c:244(read_packet_remainder)
Jun 29 14:56:28 dorgee smbd[2382]: read_fd_with_timeout failed for client 192.168.1.81 read error = NT_STATUS_END_OF_FILE.

From Wireshark:
After the FTP i.e after "14:56:20":
- the station make a SMTP query
- there is a Client Hello
- an exchange of keys
- some packets with TLSv1.2 protocols
- Another Hello
- another exchange of keys
- then the station is asking for the main web page in Primary i-bay
- when the web page is finished, the station is asking a lot of pages from the cgi directory. The server always responds with 404.
I compared the time (14:56:28) to the last 404 and this is the time of the message "...NT_STATUS_END_OF_FILE..."

Why is the station asking for the main page of the Primary i-bay?
Why the station is asking files from the cgi folder?

Thank you for any suggestions,

Michel-André

FOUND THE CULPRIT

If I uninstall AVAST antivirus, there is no more message END_OF_FILE

Now I would like to configure AVAST or SME to get rid of the problem.

Any suggestions...

With Avast installed on Windows, you could look at the Windows running processes & disable the culprit (if found & if possible/practical).

You should really be asking on an Avast forum.

I'm guessing AVAST is 'phoning home' to look for any updates. Maybe it configurable in AVAST?

So what we have: FTP, IP, Application, Type of traffic... Maybe there is something in the mix?
Title: Re: read error = NT_STATUS_END_OF_FILE
Post by: michelandre on July 04, 2015, 02:34:44 AM: Hi all,

TOTAL VICTORY :)

- I created a new user in SME
- I created a new account at Avast with the credentials of the new user from SME
- I downloaded a new "avast_free_antivirus_setup_online.exe"
- I downloaded the uninstaller "avastclear.exe"
- I uninstalled with the uninstaller "avastclear.exe"
- Clean all the data in "C:\Users\...\AppData..."
- I Installed a new Avast with "avast_free_antivirus_setup_online.exe"
- I configured Avast
- I registered directly from Avast panel "Settings | Registration" with the new user from SME email address

A real miracle, everything worked fine with no message "error...END_OF_FILE..."

After 2 months, it's about time...

Can someone explain why so many entries so often from DHCP

I hope it's not related to Avast - it is almost again every 10 minutes :-x.

Again, thank you all for your suggestions.

PS: Avast forum is nothing compared to the quality of SME forum.
