Problem starting the jBase Telnetd Server

[alvinpaul]

Hi,

Has anyone encountered this problem? When I start the jBase Telnetd
Server it shows me this error:

"
Could not start the jBASE Telnetd Server service on Local Computer

Error: 1067 the process terminated unexpectedly
"

We are encountering this problem in several of our laptops which has
different configurations and installation.

Regards,

Try this from a command prompt:

>jservcontrol telnet remove
>jservcontrol -s auto -p telnet C:\JBASE30\telnet\telnetd.exe telnet install

Then try starting the service.

Hi Jim,

I tried this:

jservcontrol telnet remove
jservcontrol -s auto -p D:\Database\JBASE40\telnet\telnetd.exe telnet
install

and the problem still persists...

Alvin,

Try changing the telnet port from 23 to something else. In the
services file add the following line:

jtelnet ###/tcp jbase #jBASE telnet port

Where ###/tcp is the new tcp port you want to use. I have found that
using 223/tcp works fine.

You will need to stop the jBASE telnet service and restart and of
course change all of your emulators to reflect the port.

Hope this helps,

Rick

Do you have another telnet server installed on the same system?
UniVerse? Windows built-in?

Jim

I have seen the same behavior with a "firewall gone mad" or another process of some kind listening on port 23...

Try using the netstat command to verify that nothing else is on 23...especially if you can start it on a different port as Rick suggested above.

Hi Alvin,

If you are on Windows XP with service pack 2, check whether you have the
permission for telnet.

Hi Jim,

Yes, I have Universe but it is not running. Previously, I can run it
without any problems. I haven't installed any other software since
then, except for Windows Hotfixes...

Alvin

[alvinpaul]

Hi Jeff,

There is nothing running on port 23. What I dont understand is, when I
try to run the Universe Telnet Service, it is working fine. But when I
start running the jBASE Telnet service, this problem occurs...

Regards,
Alvin

[alvinpaul]

When I installed jBASE on this machine, I am already using Service Pack
2 and it was working fine. It just happened one day when I try to start
the service.

[alvinpaul]

Hi Rick,

Where can i find this jtelnet program? It doesn't seem to exist in my
bin and telnet folder?

Regards,
Alvin

Alvin,

You wouldn't have happened to install Security Update 902400 for 2003 and XP?  That one caused 2 of our clients to go down (UniVerse and jBASE).  I think it was because of the link between jBASE and COM+, but not sure.  We had to explicitely grant the local SYSTEM account Full Control with NTFS security on the drive jBASE is installed, and the drive your data accounts are created on.  I had to make it replace all existing permissions by using the advanced tab in Security...

UniVerse Telnet started, but aborted when a user authenticated, while the jBASE Telnetd would not even start...

Jeff

[Rick Weiser]

Alvin,

By default jBase uses port 23 as does Universe. You will need to
change either Universe or jBASE to use a different port. I have
already explained what you need to do change the jBASE port. As for
Universe, I think you can use the UV admin to change this.

You will need to change on of these or the jBASE telnet won't work.

Rick

Hi Jeff,

All of us who encountered this problem installed Security Update 902400
for XP. Thanks for the info =)

Hi Alvin,

 

Have you solved this problem then?

 

I have a slimilar situation with my laptop (Win XP, jBase 4.1.4.16, SP 2 installed). I uninstalled the Security Update 902400 but the problem still exists. The Windows event log contains error messages which sound something like this: "cannot open port for telnet, try adding telnet to the \winnt\system32\drivers\...\services".

I also tried out solutions sugested by Jim Young and Rick Weiser but with no success.

 

Looking for a solution,

Sandy

We have a machine that has the problem also. (Win XP, jbase 3.4)

The services file seems to be okay (replaced it with one from a working
machine, just in case).

Interestingly, it is not just jBase - if I do a :

telnet some.mail.server pop3
on the broken machine, it fails (telnet some.mail.server 110
works)

on another machine w/902400, that command succeeds.

Anyone have any other thoughts? A MSN messenger update happened on
the machine in question at the date of failure. That has been removed,
with no help.

Hi all -

If anyone else is still having this trouble (cannot start jbase
Telnet server due to 'cannot find telnet in services file'), here is
the solution I found: It appears that MSN Messager changes a registry
value from REG_EXPAND_SZ to REG_SZ. It should be REG_EXPAND_SZ.

Steve
CMI

----

MSN Messenger 7.5,Connection Troubleshooter

Reason and Prerequisites
The reason for this malfunction is, that the datatype of the registry
value

HKLM\System\CurrentControlSet\Services\TCPIP\Param
eters\DatabasePath

was changed from REG_EXPAND_SZ to REG_SZ.

The following programs are currently known to cause this registry
change:

Starting MSN Messenger 7.5 "Connection Troubleshooter" (Build
7.5.0299).
Installation of MSN Messenger 7.0 or MSN Messenger 7.5 with the option
autom
atic scanning and configuration of ports.
This modification prevents the expansion of environment variables in
the val
ue of the parameter. Therefore,

%SystemRoot%\system32\drivers\etc

is not translated to

c:\windows\system32\drivers\etc

and the services database is not found by the API function
getservbyname().

[Doug Chanco]

I may be broadcasting my windows ignorance BUT what in the world does
msn messenger have to do with a telent server working or why does msn
messenger modify a registry setting that causes a telnet server to quit
working?

the more of these threads I see, the more I wonder why people would use
windows as a jBase server versus Linux/unix (not that I want to start a
windows vs linux war) but I am curious .......

[Clif Bristol]

In my case the decision to use windows was not a technical but a marketing/managment decision. Enough said?

You should be getting lots of cheques in the mail for this one. I am
certainly filing your findings under "jbase tech" in my mail system.

>From the looks of the fix it has Messenger has nothing to do with telnet but
looks like it hoses the TCP/IP configuration and expansion of environment
variables.

Why would someone install MS Messenger on a server anyway?

Kevin Bilbee

[Simon Verona]

I've never found Windows a difficult medium for deliverying jBase on.
Certainly, whilst Microsoft have the habit of "breaking" some things from
time to time in the name of security patches or the like, I don't think this
compares to some of the hell I recall getting a linux system up and running
(though I understand that this is much easier than when I last looked!).

At the end of the day, it's what you get used to. I'm used to working
with Windows and so don't have a problem. You certainly - for example -
don't run msn messenger on a production Windows server running jBase!

Simon

To expand (ho ho ho), it looks like there is a bug in the MSN
integration that changes the data type of a registry entry that it
should not.

This seems to affect the API functions ..byname() and this is what is
used to find out what port the telnet service is on and so on by looking
at the port mapping databse. If this database is no longer accessible,
then strange things will happen.

Not environment variables, this is a data type within the register data
set. The service database allows you to find out what port a service
is/should be listening on if you already know the name, such as dns, or
telnet or jtelnet etc.

Jim,
if you were any smarter, they would need to create a new plant for

And then we could do a movie based on it! And equels "Benath the planet
