Re: Can't access Web Interface

Hi kj,

 

if you suddently stop accessing CWIS (webpage) but you can still access it via other web-browsers. Very likely you are using SSL and I might suspect of the certificates being used on the device.

 

Microsoft has launch and update for IE which updates the minimum certificate key lenght. Devices will have to use certificates with a minimum of 1024bits in lenght.

 

Specificaly to Xerox, some devices do not support such certificates. So far the only thing I can advise is to (at your own risk) use another browser, eventually do not use MS update (be aware of the risk and security awareness announced at microsoft before you take this responsability).

 

Nevertheless I do not have any official anwser or plan from Xerox towards this.

Re: Can't access Web Interface

Hi RuiC-Xerox.  You must be right about the certificates. So I assume there's nothing I can do to change the settings to get the CWIS to work with IE.  Guess I'll just have to use a different web browser. 

 

Thank you very much for your help.

Re: Can't access Web Interface

I just encountered this myself, actually, on our Xerox WorkCentre 7335.  You can re-generate a self-signed certificate, at 1024 bit length, to resolve the problem.  Here's what I did to do so (YMMV, as always!):

 

  1.  Use Firefox or an alternate browser to access the web management interface for the device, and authenticate as the device admin.
  2.  On the Properies tab, expand Security, then click Machine Digital Certificate Management.
  3.  Click "Create New Self Signed Certificate".
  4.  Set the Public Key Size value to 1024 bits, and set the issuer to the hostname or IP address of your device.
  5.  Click Apply.
  6.  Your device should now have a 1024-bit self-signed certificate, and should again be accessible via Internet Explorer (running IE9 on Win7 Pro here.)

Hope this helps!

Re: Can't access Web Interface

Hi craigpower,

thank you for your post. This is in fact correct. You can recreate the self-signed certificate at 1024 and this will (should) work.

 

On majority of the models there should a link on the support page on how to create or load certificates, example on 73xx series.

 

Unfortunately I am not sure that all products will support 1024 certificates creation. Nevertheless majority should.

Re: Can't access Web Interface

I don't have access with any browser. How can I send a SNMP command to reset/reissue the certificate?

It seems like sending a clone file will reset the certificate but in some cases, it doesn't.
