NNTP: "You have no permission to talk"

Recently I starting to receive this message, while tried to
use news. Mail (SMTP), WWW, FTP works OK. I thought that it's
Netscape 4.5, but same message goes from IE and even from
WinVN. Reinstalled MSDUN - no luck. Service guys said, that
their news work OK (sure thing :), so I think that fault is
on my side. Auto-run tasks all the same: Cpuidle, RVS Port
Server (maps ISDN on COM port), Moony Caller ID detector,
CleanSweep detector modules.
PS: DeviceManager has some "DialUp with VPN" as well as normal
DialUp adapter listed, but it sits there long time.

======================================================================
---------------------------------------------------------------------------
The information in this article applies to:
 
 - Microsoft Exchange Server version 5.5
---------------------------------------------------------------------------
 
SYMPTOMS
========
 
When you set up the Internet News Service for Microsoft Exchange Server
5.5, and you attempt to connect to another host Network News Transfer
Protocol (NNTP) server, the following error message may appear:
 
   502 You Have No Permission to Talk
 
CAUSE
=====
 
This error can occur if you try to connect to a host server that does not
allow access from your IP address.
 
This is a security measure that allows Internet Service Providers (ISPs) to
restrict access to their NNTP server.
 
RESOLUTION
==========
 
If you are setting up a new connection with an NNTP server, your ISP needs
to include the IP address (or range of addresses) of your Exchange Server
computer, explicitly in order to allow you to connect.
 
If you do not have a static IP address (or a range of addresses) that can
be included on your newsfeed server's authorized pool for incoming
connections, then you may need to set up a secure connection using a logon
name and password.
 
To select a secure outbound connection, click the Security tab IN the
newsfeed object in the Microsoft Exchange Administrator program.
 
MORE INFORMATION
================
 
To prevent unauthorized access to their NNTP servers, Internet Service
Providers often restrict logon attempts to their own network or to a group
of IP addresses.
 
You may not see this error message unless you manually telnet to port 119
of an NNTP server for troubleshooting reasons. The telnet dialog box looks
something similar to the following:
 
   502 You have no permission to talk, Goodbye
   Connection closed by foreign host.
 
Additional query words: news, usenet

Sgenthet, sorry for rejecting, but I'm not setting Microsoft Exchange Server, I'm just
humble dial-up'er with dynamic IP address that worked 1/2 years, till past week. :)
And my account not expired: I'm just confused, because my logic tells me that
my record on NNTP server of my ISP damaged/erased. I'll try to convince them, that
it's their problem, but in the same time I'd like to hear hints if it can be my fault (and
where).

No problem...I know you didn't have exchange server ,but in the article it explains the causes of getting this error msg as being
the ISP lack of having your ip in their security.I really don't believe this is something you can do anything about.

You can test if you are authenticated to access the news server of your isp.

Just telnet to port 119 of the newsserver.  Type help (set your telnet program to echo locally first)

The issue some nntp commands and see if they work.  If the nntp server needs authentication it will complain about it.  You can log in manually by using the authinfo command

joopv, good hint. From home: "you have no permission to talk" and
"cannot connect". From work: "conection refused".

Probably at work you have to work via a proxy/firewall ?  I'm not sure if this will block your tcp port 119 traffic.  Where i work it will.

Experiment with a public (no authentication needed) news server like cs.intel.com ans see how it reacts to your manually given nntp commands.

oops, i meant this to be a comment, not an answer.

another thing to check is your local config : see if it has something like 'this news server needs you to log in using this username and this password' and check the values.

He-he. You right, at work I have proxy/firewall, but I telnet'ed
to site which doesn't have it and from it telnet'ed to news.
. OK, I got it by telnet. Now syntax of authinfo is
authinfo user Name|pass Password|generic <prog> <args>
I tried to put:
authinfo user _my_username_ pass _my_password (answer is PASS required)
authinfo user _my_username (answer is PASS required)
authinfo pass _my_password (answer is telnet jumped out and auth  error:)

Do I miss something ?

I had this problem with Netscape V 4.03 but when I checked at the time my clock had been reset - now isn't that something wild, anyhow when I reset the clock the error did not reappear. Also after I upgraded to V 4.06 the problem dissapeared, BTW frustrated with h.disk problems with Netscape I now use MS Explorer. Also if on the net a lot, you may have a virus - do get an antivirus package.
RE
Netscape cache and malicious java code - the easy way to get rid of this sort of silliness is to delete the cache folder from the Nestscape directory. It does not affect the performance of netscape and it does deal quickly with these type of problems - I do recall one occasion where I got the error 'No permission to talk' and I did close down NS dissconnect, delete the cache folder, log on again reload NS then post my comments.
These viruses are becomming tooo much really !

Hi all. Now it's clear to me that it's ISP problem. I have several news.* server names. Old one
suddenly asked my login/password and failed, second, suddenly as well, started to receive news
WITHOUT any authentication.

Ok so i understand your problem is solved or at least you are looking with your ISP to find it out.  It is strange since most isp's use special protocols to authenticate (RADIUS/TACACS) and it usually means that once you are in, you don't have to authenticate every service, just once at login.

Good luck
