SLM2048 - Password problems with special chars

Hi all,
We´ve got a SLM2048 in use  (most current FW) and I wanted to apply our new password standards  onto that switch. So I changed the password of the user admin and used  special chars, which were =&!= and clicked update and save changes. I  now know, that I should have been using only alphanumerical characters,  but why is there no routine that checks the PW for conformance, before  writing it onto the switch.
Problem now is, that I am unable to login and  don´t want to do a hard reset, because the configuration would be lost. I  know there should have been a rescue admin user, but there is none.  What can I do now? Any chance that a cisco engineer could get in contact  with me to debug the entered password in the lab and who could then  tell me what was saved to ROM or how I can login again?
Thanks,
Philip

If your switch has a console port, you can try this:

  • Problem with special chars in BLOB datatype using contains keyword

    Facing problem, when part searching with special chars in BLOB datatype. It is considering the non alpha-numeric chars as a separtor in a provided string
    EX:
    SELECT *
    FROM RESUME_TEST P,grst_candidate d
    WHERE d.candidate_id = p.candidate_id
    AND CONTAINS(P.CAND_RESUME,'%VB.NET%',1) > 0
    Strings: , VB.NET , PL/SQL AS/400 , C etc..
    Followed the below approaches
    1) created a table:
    Syntax: create table resume_Test(cand_id number(10),cand_resume blob);
    2) inserted the values into this table upto 60,000
    3) created a context index
    3.1 created preferences
    Syntax:
    BEGIN
    ctx_ddl.create_preference('try_lexer3','BASIC_LEXER');
    ctx_ddl.set_attribute('try_lexer3','printjoins','-_~!@#$%^&*(){}[],=?\;|><.+');
    END;
    3.2 created context index
    Syntax:
    CREATE INDEX CANDRESUME_CTX_IDX ON resume_test (cand_resume)
    INDEXTYPE IS CTXSYS.CONTEXT
    PARAMETERS ('LEXER try_lexer3 memory 500M');
    4) while executing this index, it is taking much time approx 6 hrs(plz explain why it is taking time)
    5) Problems:
    5.1 when searching with string(VB.NET , PL/SQL AS/400 , C etc..) it is considering the special char as a separator
    5.2 used escape char (\) also, but no effect
    5.3 when searching with single char, it is giving error (ORA-29902,ORA-20000,DRG-51030)
    5.4 getting the above error with wild card chars (& ,_, (),{},[])
    So, please explain the clear scenarios, why am getting this error , and how to get the proper results.

    Have you tried adding the / char to the printjoin characters?
    Indexing can take a lot of time, depending on the amount of data and your machine's power. You could try to parallelize the index creation and / or assign more memory
    CREATE INDEX CANDRESUME_CTX_IDX ON resume_test (cand_resume)
    INDEXTYPE IS CTXSYS.CONTEXT
    PARAMETERS ('LEXER try_lexer3 memory 2000M') PARALLEL 8;

  • Problems with special characters in InputStream or XPath

    Hello everyone,
    I am having problems with special characters such as ", ', - and so on, everything becomes ? (questionmark). (Not with special nordic characthers (å,æ,ø) though.)
    The encoding of the XML is UTF-8, and the server that holds the webservice is setting encoding to UTF-8 also, so no conflict there.
    What I have done is something like this:
    {code}
    String url = "http://www.formula1.com/rss/news/latest.rss"; // This is not the feed I use, it is a custom XML document
    InputSource is = new InputSource(url);
    DocumentBuilderFactory fct = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = fct.newDocumentBuilder();
    Document doc = builder.parse(is);
    Element rootElement = doc.getDocumentElement();
    XPathFactory factory = XPathFactory.newInstance();
    XPath xPath = factory.newXPath();
    out.print(xPath.evaluate("/rss/channel/title", rootElement)); // The xml is not a RSS feed, this is just an example.
    {code}
    Please let me know what I am doing wrong, or give me a hint of how to solve this in another way.

    Hello, thanks for you reply. I had to rewrite your code a little, and I think that your code would not really compile, if you tried yourself :-)
    I ended up with something like this:
    our environment is running in 1.4 mode, so I could not use the for-each loop :-(
    public String printEntities(String s) {
         char[] sArray = s.toCharArray();
         StringBuffer sb = new StringBuffer();
           for (int i = 0; i < sArray.length; i++) {
             if (sArray[i] > 256)
                  sb.append("&#x" + Integer.toHexString(sArray) + ";");
         } else
              sb.append(sArray[i]);
         return sb.toString();

  • Problems with special characters like "u00F6" "u00E4" "u00FC"

    Hi,
    we currently face some major problems with special characters like "ö" "ä" "ü". First I thought it is a SP02 specific problem but it still doesn't work with SP03.
    When I start an import the import manager shows correct converted value. "ö"s "ä"s "ü"s are displayed correctly. But after I've done the import I look into the Data manager and I see instead of these characters charcaters like "&#776;". (note: the character should show a little square box - but the forum cannot desplay it)
    How can I solve this problem?
    Regards
    Nico

    Hi Nico
      Just try it out the following steps, hope it solves ur issue.
    <b>To set one or more values back to their original values:</b>
    1. In the Import Manager Source Values grid, select the values that you want to set back to their original values.
    2. Right-click on one of the values and choose Set to Original Value from the context menu, or choose Values > Apply Value Conversion Filter > Set to Original Value from the main menu.
    3. MDME sets each value back to its original value, which appears in black in the Source Values grid.
    <b>NOTE : You can use the Set to Original Value filter only at the value-level and not at the field level.</b>
    thanks

  • Vibe 3.2 problems with special characters?

    I'm not sure where the issue lies here, the client or Vibe, so I'll throw
    this out there to see if anyone has run into this problem. I have a user
    with a + sign in their password. If he tries to log in from either his
    Android phone or his Android tablet, he gets a bad password error. Using a
    different browser on the tablet, he was able to get logged in. Using my
    Android phone, he was also able to get logged in.
    Are there any known issues with Vibe not supporting certain browsers for
    special characters in passwords? I don't think he had the problem with Vibe
    3.1.

    Yes, you're right. Same issue here with a '' character. Found this:
    '6.2 Character Restrictions in Usernames and Passwords
    Do not use extended characters or double-byte characters in Novell Vibe usernames and passwords.
    This includes usernames and passwords that are synchronized from an LDAP directory into Vibe.
    This limitation is caused by the open source Spring Security (http://static.springframework.org/
    spring-security/site) that Vibe uses for authentication, in combination with the various authentication
    methodsboth basic authentication (http://en.wikipedia.org/wiki/Basic_a...authentication) and
    form-based authentication (http://en.wikipedia.org/wiki/Form_ba...tication)used by
    single sign-on products such as Novell Authentication Manager, by Web services, and by WebDAV.
    Only ASCII characters are properly interpreted in all combinations.'

  • Problem with special characters! Need a big help!

    Hello!
    Please be patient with me. English is not my main language.
    I have a big problem with my countries special chars.
    Our spec. chrs are á,é,í,ó,ö,ő,ú,ü,ű
    When I save a document every other characters (even other special chars) are okey, but ő and ű will be o and u after saving my document.
    This is really annoy me. I've read a lot of forums in my country, but I can't find any solution.
    When I go to "Edit > Preferences > Fonts" and no document is open, Font Settings: Unicode
    If I change this, and I reopen this window it will be on Unicode again. I can't change it.
    When I go to "Edit > Preferences > Fonts" and my documents are open, Font Settings: "Nyugat-európai" (means Western European)
    If I change this, and I reopen this window it will be "Nyugat-európai" (Western European) again. I can't change it.
    It should be: "Közép-Európai" (means Central European) but every time I change it, it reverts to this defaults.
    Please help me!
    I have to reopen every file in Notepad and rewrite the ő,ű chars.
    Thanks,
    Averin Kilian

    Ok, solved:
    From, DW do Edit | Preferences | New Document and set the Default Encoding to
    whatever you wish it to be.  That will set the default for all new
    documents in Dreamweaver.
    For the existing pages, you will need to open them and do Modify | Page Properties | Title/Encoding to set the encoding as you desire.

  • Problem with special character like u00E5,u00E4 u00F6 in Sender JMS Adapter

    Hi,
    Problem:
    Sender JMS Adapter has transformation error when the file includes western european characters such as å,ä ö. And because of this reason the data is not picked up by adapter.
    The scenrio is JMS --- > XI ---> Proxy.
    If the file does not include the western European characters then it is working fine, but when the file include the western european characters such as å, ä, ö so got the error.
    Our Efforts:
    We have tried ISO8859-1 in JMS Module Tab as shown below.
    1. Transfer.ContentType text/xml;charset=ISO-8859-1
        AND with this also
    2. Transfer.ContentType application/coctet-stream;charset=ISO-8859-1
    None of them working.
    Error In CC:
    In Sender CC monitoring we are getting the below error.
    Error while processing message 'aa157082-b064-4421-0fc3-c286d2732093'; detailed error description: com.sap.aii.adapter.jms.api.channel.filter.MessageFilterException: Error converting Message: sun.io.MalformedInputException: TransformException: Error converting Message: 'sun.io.MalformedInputException' at com.sap.aii.adapter.jms.core.channel.filter.SendToModuleProcessorFilter.filter(SendToModuleProcessorFilter.java(Compiled Code)) ...

    > I think you have to figure out first, which codepage you really have, not just try. Maybe you ask someone or you check with a hex editor.
    Hi Stefan,
    Finally we solved the problem.
    As you said above to figure the the codepage, we asked to our MQ team for the same and found that they are using ISO-8859-1. In XI we were also trying with multiple conbinations (ISO-8859-1, UTF-8 and many more), but didn't get any success.
    Finally MQ team changed their encoding to UTF-8 and in XI we used ISO-8859-1 and we get the success in picking the data with spl char. Even though in XI the spl char comes in destorted order but at the receiver end they are in proper shape.
    Thanks a lot for your help.

  • Problems with special characters displaying in PDF when exported.

    I have a very frustrating question. I've never had any problems with font and pdfs before switching to the operating system for Mac. Of course, they have Helvetica Neue pre-installed as a system font. The problem is, Bold doesn't work and is not an option. I've tried using Helvetica Neue (TT) but special character and punctuation disappear completely.
    See below:
    MЧnica PОrez
    Unfortunately, that is supposed to say Monica Perez. There are supposed to be marks above the "o" and "e". Can anyone help me?

    Try copying your T1 Helvetica Neue font into the Applications/Indesign/Fonts folder. This will give you the complete family in Indesign overriding the system TT.

    We used this blog post so we could do some PDF printing with APEX Listener:

    The problem is special characters. For example the "&" sign comes out as "%26amp;" when we export an XML.
    Could anyone provide some insights of what we can do to fix this?

  • Problems with special characters in JSP app

    Hello!
    I am working for a JSP application which uses special characters.
    The database used is a Novell MySQL version, it is fine.
    I use Tomcat, Apache.
    I do not think that the versions are important.
    ON NT:
    The application works fine with special characters.
    Obs: I tried only with Tomcat; I didn't use Apache.
    ON NOVELL:
    If I try to insert some special characters,
    they arrive just fine into the database.
    The problem is when I want to display them.
    I tried with jsp directive to set the charset,
    or with HTML meta tag - no result al all.
    Everytime I use the same work station, and the same browser to do the tests.
    Please help with any ideas.
    Another question, maybe relayed:
    Can I set Tomcat so that when it creates the servlets it uses a custom charset I can indicate?
    THANK YOU!

    The characters I want to use are french characters, e-acute, etc.
    I take the data with request.getParameter, POST method, etc.

  • Problem with special characters on Safari

    Hi everyone,
    Once again, I am in desperate need of your help, as I am facing a very annoying issue on Safari (version 5.1)! Indeed, I cannot use special characters such as 'ê' on various websites, including Facebook or even this very page.
    I have a QWERTZ keyboard layout (Swiss layout), which is very handy because of its ambivalence. However, when I try the usual key combination for 'ê' (as there is no specific key for that character), which is ^+e, nothing happens. I have to type several times the '^' symbol only to get a weird bar at the bottom of my page displaying many useless '^' at the same time (see picture below).
    However, this problem does not arise whilst typing in Google's search-bar or other websites. I also checked on the Internet to see that this was a common issue but could not manage to find an answer to it.
    I hope you will, because it is really annoying to use each time a copy/past...
    Cheers!

    More likely a bug that Apple has to fix.   Do you have this problem with any other browser, like FireFox or Chrome?

  • Problem with special characteres

    Hi. I have a problem with java. I�m making an application that works with special characters and displays correctly on my local machine, as I use escape characters such as &igrave; for �. The problem is when I deploy the application on a unix machine. All of the special characters (�, �, �, etc) appear like a �?� (question mark). Any tips, please?
    Thanks in advance

Any tips, please?First step: read [this excellent introduction into Unicode|http://www.joelonsoftware.com/articles/Unicode.html], it will give you the basics you need to solve this problem.
    How do you input and output those characters? Simply print them to the console? Or write them to a HTML file (since you mention &<something>; notation)?
    "?" is normally the result when you convert a String (which is always in UTF-16 encoding in Java) to an encoding that can't represent your characters (ASCII for example).

  • Replacing space with special char in reporting

    I have created a calculatd Keyfigure where if the consition given in the calculated KF satisfies then it displays 1 otherwise space ,now mu user wants space to be replaced by some special charcter
    Example
    My ckf is like this overallscore >= 90 & Iam applying count on this
    Vendor   CKF
    X              1
    Y
    Z                1
    As vendor y is not satsifying the condition its showing with space now I want to replace space with some special char how is this possible

    Hi Priya,
    You can try this: Instead of space, fill this with a 0. Then in the query properties, set the Show Zero As and give your special char, like may be *. But this will be okay if you do not have other zeros in the report...else you may need to do some VB coding.
    Hope this helps...
