Send Me A Question!

I want you to ask me questions.

I would like to foster knowledge transfer; to and from me.

You can ask me questions about: Linux (Suse of all flavors, RedHat/CentOS/Fedora, Debian, Ubuntu, etc.), NetWare (3.2 and up), Directory Services / Identity Management / Authentication infrastructures, Solaris and other Unixes, Open-Source Software in general, wireless, etc., etc….

So, send a question to: questions@yourLinuxGuy.com

I will try to answer.  Of course it might be that you may not like the answer, but I’ll try to help, and it just might be worth a try (especially since it’s free).  If I do not know the answer, I will try to foster discussion by opening up the post for comments.

Why am I doing this?  To keep my skills fresh, to swap knowledge, to vent a bit, to share, etc….

When you send a question, make sure to tell me whether or not I should include your name if I post/answer it, as I usually like to include the sender’s first name.  All info submitted to the above email address become my “property” to use and reprint as I see fit, though I will credit you (if desired) as the author of the question/point/argument/rant.

And don’t worry, I’m not going to add you to any lists, or spam you, or anything like that.  In fact, your email address will only be used to reply regarding the question if needed… So there.

Thanks, and I hope to hear from you soon….

:)

    Hi, I’m having a problem with the iFolder client
    After getting it installed on OpenSEUS 11.1 i’ve installed the client onto windows vista and xp machine, but for some reason it can not connect to the server, it throws a soapexception:
    System.Web.Services.Protocols.SoapException: Server was unable to process request. —> System.ArgumentNullException: Key cannot be null.
    Parameter name: key
    at System.Collections.Hashtable.ContainsKey(Object key)
    at Simias.WebState..ctor(String DomainID)
    at Simias.DomainServices.DomainAgent.Login(Uri host, String domainID, NetworkCredential networkCredential, Boolean calledRecursive)
    at Simias.DomainServices.DomainAgent.Attach(String host, String user, String password)
    at Simias.Web.SimiasService.ConnectToDomain(String UserName, String Password, String Host)
    — End of inner exception stack trace —

    any ideas?

    @Alex…

    Interesting. It looks like the client is trying to do an SSL connection and cannot find the key. I found this post where a user seemed to solve a similar problem…. so…

    When you specified the server URL in the client setup, did you put “https” instead of “http”??

    Also, make sure you did/do not have any web proxy settings in use during client set up and testing.

    Let’s see if that helps….

    Jeremy, If I am looking for an old command that I know I used on the server I can use the “history” command to list all the commands but If I do not want to weed thru all of the commands in the list and I know the first part of the command let’s say “rug”. What would be the command to find everycommand that I have used in the command history that has the word “rug” in it?

    Thanks Steve…

    @Steve –

    Since you mean Suse (given rug), there are a few options:

    - Type “rug” then press the “page up” key. each time you press it, it will show the previous command starting with what you typed.

    - If you are certain that you want to re-run what you ran last time that starts with the same characters, type “!rug”, and it will run the last command you ran starting with “rug”.

    - You could just parse the user’s history, like this: grep rug /root/.bash_history or grep rug /home/jpavlov/.bash_history

    …that oughtta get you started… :)
