TYPO3 Mailingliste: nicht fragen - lesen!

I wonder if anyone has encountered this strange phenomenon...

I installed a fresh copy of TYPO3 4.2.1. When I login into the backend
the following error message pops up:

"Login-error or session timed-out
No user logged in! Sorry, I can't proceed then!

(You must have cookies enabled!)

If your session has just timed-out, you may
click here to re-login."

So I re-login but the same message pops up. My local copy of TYPO3 works
fine but this seems to happen every time on the remote installation.

Now the strange thing is my colleagues based in the other side of the
world (UK) do not get this problem when they access the same TYPO3
installation. I'm based in Hong Kong and the server is in the US.
Additionally if I VPN into the UK Office everything works fine.

OK, 7 days since I last started this thread and not a single response. I
can only assume it's just me that's the weirdo. Is it real that no one
in this list has ever encountered this problem?

*Update: *Tested on another machine and I still get the same problem.
Tested using a friend's internet connection... still same problem. The
only two commonalities are 1) Hong Kong 2) Both networks subscribe to
i-Cable broadband [1]

I also ran a check on my external IP address through What Is My IP
Adress dot com and it returned a different IP address ending every time
I refreshed the page! Could this be the cause? If so, why would it
matter? Could not a cookie on the client machine determine their identity?

That may be the catch. TYPO3 checks that your IP address matches the one
that it registered when you opened your session. Try editing your
typo3conf/localconf.php file and turning off the referer check:

$TYPO3_CONF_VARS['SYS']['doNotCheckReferer'] = '1';

Hey,

yes... the IP change might be the issue.
I have heard (and seen) some IP's using a VERY STRANGE proxy setup
on which they use a different IP address per single request. This is
VERY
annoying for all users behind such proxy servers and I feel that these
ISP's
don't have a single clue what they are doing (hobbiests!!!)

Anyways, there might be some good news for you.
In the install tool there is a 'lock IP' option, I totally forgot it's
name
but under normal conditions TYPO3 locks a lsession to a IP address,
when switching this on or off (forgot the name and values really..)
TYPO3 will
NOT check the session with the IP address anymore, this will hopefully
allow you to stay logged in.

So.... check the install tool for that option and see if that helps

That is the problem! I had the same problem with a proxy that balanced
requests among 2 externals providers. You have to be stable with your
public IP otherwise the cookie is invalidated.

I did to investigate into TYPO3's mechanism but personnaly, as I
developped website from scratch with user login, I was always including
some kind of protect mechanism to avoid cookie-theft.

Hi Ca Phun Ung,

Add the following to your localconf.php:

$TYPO3_CONF_VARS['BE']['lockIP'] = '0';

It is not an ideal solution though as you will loose the IP lock on all
BE sessions.

Best regards,

Oliver

Thanks for all the help guys. IP change is the culprit after all!

Setting [BE][lockIP] = 3 solved the problem since it was only the 4th
part of my IP that was changing.

Again, many thanks to all who responded **
