Trouble Loading Webpages -- urgent/one allows access to Citrix environment

I need access to a webpage w/in a Citrix environment to allow me to work at home. I was able to do this fine on my Powerbook G4 with 10.4.11. Just bought a MacBook Pro preloaded with Snow Leopard, and can no longer access the webpage. Also have trouble with sites using Java, Twitter won't load at all, and have some problem downloading graphics in my my email client. Use both Safari and Firefox with similar results. Really, really need some help here!

Hi, downloaded Citrix 11.0.0 in hopes of solving the problem, and it's not working either.
Here's what I got on terminal:
java version "1.6.0_15"

  • Trouble loading webpage in safari ... Blank Image

    A friend of mine send me an webpage he has been working on and for some reason it will not load in Safari. I have been through the code, renamed, and deleted to no avail. The page loads fine in Firefox. The only thing that I can figure out is that if you remove the swap image functions it will work again, but he insists that he needs that, and I must admit I have used that function many times in layers / tables with no problems.

  • [Solved]gnome-system-tools You are not allowed access to sys config

    I did a FTP install of i686 Arch Linux on a friend's machine.  I could not get gnome-system-tools to work, keep getting:
    The configuration could not be loaded
    You are not allowed access to the system configuration
    So, I tried gnome-system-tools on an i686 Arch install on my machine, and gnome-system-tools worked.  Then I did a pacman -Syu  and fully updated the system.  The updates included udev which now prints how long udev events took on boot up.  After the updates, gnome-system-tools no longer works.  Same symptoms as the new install.
    Both machines have stbd in the /etc/rc.conf DAEMONS line.  Both the user and root in both machines are part of the stb-admin group.  Using gksu or launching as root in a terminal window results in the same problem.  The problem seems to be in system-tools-backends which works in conjuntion with dbus as I get this error:
    (time-admin:7607): Liboobs-WARNING **: There was an unknown error communicating with the backends:
    Process /usr/share/system-tools-backends-2.0/scripts/SystemToolsBackends.pl exited with status 127
    gnome-system-tools and system-tools-backends are part of the community group, so as far as I know, writing a bug report is out.  Both gnome-system-tools and system-tools-backends are out of date in community.  system-tools-backends is version 2.4.1 and the current version is 2.6.0.  I tried using makepkg to compile the new 2.6.0 version of system-tools-backends but it fails saying it needs dbus >= 1.1.2 but version of dbus is 1.0.2.  So it appears that dbus is out of date also.  That is a far as I got.
    I know this has been a problem in the past, but I got it working until this latest update. 
    Anyone got any ideas on this?

    I've had the same problem with my users-admin and users-time... I've tried all the fixes from most of these posts... except for that string of code that someone wrote in this post: http://bbs.archlinux.org/viewtopic.php?id=42910
    for file in `pacman -Ql gnome-system-tools | grep desktop | cut -d" " -f2`; do cat $file | sudo sed 's/\(^Exec=\)\(.*-admin\)/\1gksudo \2/g' | sudo tee temp.desktop.tmp; sudo mv temp.desktop.tmp $file; done
    I wasn't sure what this string actually would do, so I haven't tried it yet. I figured there would be an easier way of fixing this problem. Like a simple edit in the SystemToolsBackends.pl file.....
    any help would be cool.

  • Cannot directly open the browser from the icon. "problem loading webpage" and "timed out" are the messages. Access was accomplished by using yahoo messenger and opening my email. if I attempt to open a new page, I recieve the aforementioned warnings.

    no link to open access to the internet. I used Yahoo Messenger, clicked on the 'mail icon' and since Firefox is my default it opened and I was able to continue from there. If I try to click File, open New Page, I get the "problem loading webpage" and "connection timed out" messages

    changed my homepage to Yahoo. Now Firrefox works but still cannot access ANYTHING 'Google"!

  • Is there a way to set firefox so it only allows access to only one website / (ip address).

    Is there a way to set firefox so it only allows access to only one website / (ip address) and block traffic from everything else (the entire web) other than the one site I want to allow? The site I want to allow is a corporate web application that will only work in firefox. We as a business run a windows server and all client desktops run Internet Explorer with security setting controlled by group policy. We have already locked down the security setting in firefox so users can’t bypass the proxy server settings.

    I have a proxy server set up (Symantec.cloud). Fire fox is “locked” so users would find it difficult to bypass it.
    I have a file: '''local-settings.js '''
    This is located in: C:\Program Files (x86)\Mozilla Firefox\defaults\pref
    The content of this file is:
    ''pref("general.config.obscure_value", 0); // only needed if you do not want to obscure the content with ROT-13
    pref("general.config.filename", "mozilla.cfg");''
    I also have the file: called: '''mozilla.cfg'''
    This is located: C:\Program Files (x86)\Mozilla Firefox
    The contents of this file is:
    lockPref("network.proxy.type", 5);
    All that is working fine, users can’t easily change the connection settings.
    So all that is good and works…
    What I would also like to do is set firefox so access is limited to 1 IP address and nothing else is allowed (the whole internet is blocked, except this one IP address).
    You suggest using a PAC file - I was unsure how I would use a PAC file, (I have never written one) and do not understand how I would implement one? Please help.

    That's just not right - I mean, it really wrong to have to use a Windows machine to access your Facebook account. Can you pull up Comcast on IE as well?
    Something's going on and I'm surprised that deleting your cache and cookies for those sites didn't work.
    Let me fool around a bit - what's your primary browser?

  • I'm not allowed access to my own files...

    Hello all,
    Just talked to an Adobe person on the Chat, but he couldn't help me, he told me to get someone on the phone... on the phone, they told me they couldn't help me because my product was too old... they told me to come here and ask for help... now I just hope you guys aren't going to tell me you can't help me, because of some other sort of reason!
    Here's my problem:
    For a few years now, I use a CS2 for work, both on my office-computer and on my home computer. 
    Ever since I installed it, on one of the computers the updates of Adobe Acrobat keep popping up, but only get halfway. They start installing, announcing themselves: “Adobe is now installing Acrobat 7.1…” and suddenly, it stops and says: “Windows finds it impossible
    to write onto the file  C:\Program files\Adobe\Adobe Acrobat\Activex\AcroIEhelper.dll.  Check if you have access to this file”.
    It gives me the choice between “resume, ignore, or abort”.  If I choose resume or ignore, the installation goes on till the end and I am asked to reboot. As if everything has gone well.
    But it hasn’t.  For when I do, after the computer’s started up again, instead of having an updated Acrobat, the update starts all over again:
    “now installing Acrobat 7.1…” until the reboot, the same way again, and so ad infitum.
    After a few times, I actually went checking in my computer for this location, to see what was wrong with this file on which Windows seemed to have so much trouble “writing onto”. I searched for the file called AcroIEhelper.dll, but found it wasn’t there…  No wonder they couldn’t write anything on it, I thought!
    I copied the file from my disk in the CS-box, and placed it exactly on the location it was supposed to be; at least, that’s what I tried to do,
    but soon as I did, a box appeared saying: “You are not allowed to execute this transaction”    (or something of the sort – I’m translating from
    Dutch here).  No matter howmany times I try, it always stops me, blocking my access.
    It never says why, however.
    So, the update is never really finished, I know that now, it's for lack of this blasted file. But I'm never allowed to put it where it belongs. 
    Ever since, each day when switching on my computer, the first thing I have to do is to stop this Adobe Acrobat update, which
    stubbornly -and uselessly- starts installing, before I can start working.  Every single day, and I am sick of it! 
    The computer it happens on is the second one I installed the CS on, it's a Vista.  I don't think that's the problem, though.  Would it?
    I was assured I could install my CS on 3 systems, this was the second. The one in my office is an XP Pro.
    Anybody can give me the answer to the refusal of this file? Why am I not allowed access to the files in my own computer?  And is there a
    way to MAKE the thing give me access?
    Tanks for any help...

    Thanks, Markerline. I couldn't reply this weekend, since I had omitted to send my login-password on this forum to my home-computer.  It's at home I'm having the problem: over here at work, nothing bothers asking me if I want to be updated.  (I don't even know whether I'm getting updated at all; I'm not allowed to experiment much whith this one, since I'm in the National network...
    I think I've tried it most of the times from an ampty desktop. Nothing to do with Adobe nor anything else working yet.  After all, the update is the first thing that pops up after startup; I have to abort it before I can start doing anything.
    I'll try it again, after reading the articles you write about. I might find the answer if I learn more of what this IEhelperthingy is all about.  It's really small, a few 5 MB or so; but it seems to be important enough to cause trouble.
    If I never manage to force-squeeze it into the Adobe file, my only hope is to get rid of these eternal useless attempts to update to Acrobat 7.1.  I'd be happy to go on working with number 6 or whatever I have right now, as long as I'm not constantly pestered by a never-ending update.  
    My old computer never told me I wasn't allowed to do what I wanted to it, the way this one does. I find it annoying! It makes me feel like it takes me for a fool....

    Allowing access to select few public objects
    Author: COOLNM Posts: 5 Registered: 12/21/05
    Dec 21, 2005 9:59 AM
    I am developing a java application. I need to provide some scripting support (using Jython or Rhino) to my application so that the user can better use my application. Now the problem is I just want a select few public objects to be accesible via scripts and not all public objects I have written internally. I read somewhere that class name and code obfuscation could be a option but not a full proof solution. Can anyone suggest how a full proof solution can be achieved? Would running the script interpreter in seperate JVM help (and propogate the calls to the original JVM) ? Would a custom class loader help? Please suggest.
    Thanks,

    Can anyone suggest how a full proof solution can be achieved?With jython, you could write custom PyObject subclasses (or general java facade classes) to expose only the methods you want to. The former technique allows more cool scripting functionality, the latter would presumably work in other interpreters. This would have to be done for every object you want to expose.
    Alternatively, you could enable a SecurityManager and allow only trusted code to invoke yours.

    No.Could you please explain why this wouldn't work?
    The plan is:
    Let say I have 2 public objects A & B and I want the user to only use A via their scripts.
    In JVM1: I use both A & B
    In JVM2: I write a psuedo A and not B. For all the methods of A, I propogate the calls to JVM1 (I think this is achievable but not sure how)
    The script interpreter runs on JVM2.
    Now if the user tries to access A then the call would go to JVM1 but if he tries to access B then there is no B available in JVM2 so the user cant access B.
    I know this method could be heavy as each call would have to go from JVM1 to JVM2.
    By sepeate JVMs I mean seperate instance of java.

    RMI has a way for multiple JVMs to communicate programmatically; you could also use sockets on the loopback network device (localhost). These techniques are how mature Java products constrain their number of running instances to a finite number (usually 1), they terminate any starting JVM early in the initialization procedures of the main method if the "already-running test" indicates one is running.
    If you use the networking method, you could basically read from a ServerSocket on the "executing" JVM, while the "scripting" JVM writes to a Socket. Then use reflection in the executing (server) side to determine if the method or object being referenced is one you want to expose. If not, do something -- like write back to the client that the method invocation was invalid. Reflection will slow down your code a lot though, so I don't recommend it for apps that already take up 50 megs or more of RAM ;)

    No.

    Ya, the seperate JVM approach seems complex and might not be fully achievable.
    Can someone give small code snippets on how the method level control be achieved using Java SecurityManager. Just a recap on what I am trying to achieve -
    A & B are two public objects defined internally by my app.
    I have to give the user of my app the ability to write some code. But only B
    is to be exposed to client and not A.
    Let say I have this code -
    Object A = Interpreter.InitializeEngine(..);
    A.executeFromUser(stdin);
    The user mostly uses some scripting language, say Python and the Interpreter
    is Jython. Now my Interpreter is capable of understanding calls to Java
    objects from Python. If the user tries to access B via the scripts then it
    should be allowed to do so but access to A should not be allowed via the
    scripting language.

    What you probably want is to give the user access to an interface - not a class - that only exposes the methods that you want to expose.
    This is the way all RMI APIs are exposed to client programs.

    Just one more comment. You haven't said very much about the runtime model of the scripting environment vs your java environment. How many processes do you expect to have running to make the system work? Are you expecting your java code to wind up in a jar file and get loaded by the Python process? Or are you planning on the java code executing in a separate process? If the latter, then RMI is probably your best bet.

    I haven't finalized on the runtime model yet as the scripting security issue is still not resolved. But I am sure that the java app code would init and run the scripting code and not the other way round. The app is pretty huge with heavy UI. Ya, the java code would be wrapped in jars (but mostly not in a single jar as I dont want the jar to be too hefty).
    Can someone comment on the use of SecurityManager in this case. My initial investigation shows that the objective on implementing method level security can't be implemented by this.

    My initial reply suggested writing a facade in java or by subclass PyObject. I highly recommend this path for ease of development, use, and runtime performance.
    Given that you don't understand the basics of java security, I will recommend this again.

    I have started investigating on facade in java and subclassing PyObject. But I am not sure how these would resolve the primary issue. Even if I use these and if the script writer knows that there is a public class, say XYZ in my app then he can always access that class directly skipping my subclassed PyObject or the Java facade. Or am I missing something here?

    skipping my subclassed PyObject or the Java facade. Or am I missing something here?Presumably your objects are somehow connected to the application. Your user could do something like:
    from com.foo import Player
    p = Player()
    p.setGold(Integer.MAX_VALUE)But of course the new Player object would not be part of the game. Now if you have some kind of static/singleton game state, then the malicious user could insert the Player into the game model...
    The real trick lies in understanding how to setup the jython interpreter. If your interpreter classloader can only load facade classes (and system classes) then the client script could not load other classes. There is also a hook for the import keyword so you could disallow importing java classes. Each interpretor instance has the ability to setup the locals and globals for the session so you can insert live game objects.
    I am only familiar with jythons internals, so this may or may not be applicable to rhino.

  • [Help: Urgent] problems with accessing /console after apparent successful install of Portal server SP3.0sp3a

    Hi,
    HW: Sun Solaris 2.8
    I would really appreciate it you can cc: me if you can shed any light
    as
    to whats going wrong, and what I should do to fix the following
    problem.
    Portal server doesn't allow one to access /console (or /login) -
    0 length document is returned.
    We find the following in the enterprise server error log, when we
    attempt
    to access portal console (URI: http://....:8080/console)
    1) Installed SP3.0sp3a as Open Portal, i.e without the gateway and
    without
    SSL enabled.
    2) Our Unix users are served using YP

    Stated views are my own IDEA, as I'm another I.D.E.A man "I Didn't

    Just one more thing:
    I made the following setting in platform.conf
    ips.debug=on
    Now, the trace I see on the STDOUT/STDERR stream reveals :
