• java.security.AccessControlException: access denied using Java Web Start

  - by killiancomputers

  I am having some issues with accessing files using JWS (Java Web Start). The program adds a new label and image. The program runs fine on my local computer but gives me pages of errors when I run the program on my remote server using JWS. Here's a sample of the error: Exception in thread "AWT-EventQueue-0" java.security.AccessControlException: access denied (java.io.FilePermission add2.png read) at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) This occurs even after making sure the images have read access. Ideas?

• Setup VPN access on a windows dedicated server for browsing

  - by Pasta

  I have a dedicated windows server. I want to create a VPN to encrypt my traffic (browsing, IM, etc) as I browse on my laptop using public wifi networks. What keywords should I be using to search Google? Are there any resources that help me do this? Most of the solutions are just to encrypt communication between the server to a machine. It does not act like an internet gateway, etc.

• Can I use imp/exp tools to migrate database from Oracle 9 to Oracle 10

  - by Karol Kolenda

  I'm subcontractor and my client wants to upgrade Oracle database from 9 to 10. Other vendor is going to perform the upgrade process, and I was asked to create whatever backup I need before the upgrade, and then recreate the environment in Oracle 10. All my data is stored in a separate database in a single schema. No fancy relations, scripts or anything like this (actual app supports different dbs: Oracle, SQL Server, Postgres so we want to avoid any DB-specific code). I was hoping to use imp/exp but I'm not sure if imp/exp are backward compatible (exp from O9 and imp to O10)? If there is a better/recommended way of dealing with similar situation, I'll be grateful for any advice.

• restrict access to IIS virtual directory from root website

  - by Senthil

  I have two domains (domain1.com and domain2.com). Both of them use the same Windows hosting server with IIS7. One of the domains is being called the "primary domain" by my hosting provider (GoDaddy) and it always points to the root folder that I was given. For the other domain, I have created a virtual directory in IIS and pointed it there. The folder structure is like this - root/ --Default.aspx --SomeFile.aspx --domain2folder/ ----Default.aspx ----Domain2SomeFile.aspx So, if I type domain1.com, I see the regulakr Default.aspx. But if I type domain2.com, I am shown the contents of domain2folder as if it were a separate web application - I think that is what IIS virtual directory is meant for. Well and good. But the problem is, when I type http://domain1.com/domain2folder, I see the domain2's website! But I don't want that to be shown when I use the path like that from domain1. Only if they use domain2.com, user should be able to see those contents. How can I do that? Hope I am making sense. Thanks.

• Kohana v3 ACL A2 with database support

  - by Asif

  Hi, I am using Kohana V 3.0.3. I was looking for ACL library and found from http://dev.kohanaphp.com/projects A2 Kohana's ACL module. Apparently it's found that, it manages Roles,Resources and Rules using config file and authenticate object basis. I want it to be dynamic, like Resources and Rules should be loaded from database dynamically if valid user logs in. Auth part is done now looking for ACL part. Is it possible to use same A2 module with database or need to rewrite own logic?

• Can't access Linux machine from the network, network from the machine is fine

  - by Matt

  I'm having issues with a machine that stopped replicating with mysql. It's managed by a guy on another continent but recently I've had to get involved. The server is running Ubuntu server 9.10 I can't log in with SSH, there is no response. On the server itself I can ssh to localhost fine. I thought maybe it's the firewall rules. I'm no expert on IP Tables, but I believe that's not the issue as I removed all the rules. But it still won't let me in. Any ideas? it's acting from other machines as though the service isn't listening, but I know that it is. It's like this for all services.

• Gmail 3-legged OAuth access -- Zend_Mail_Protocol_Exception

  - by tchaymore

  I'm trying to access Gmail by using three-legged Oauth PHP code provided by Google ('google-mail-xoauth-tools') here: http://code.google.com/apis/gmail/oauth/code.html. I have my domain registered and everything seems to go fine with OAuth, but after I authorize access I get this error: Fatal error: Uncaught exception 'Zend_Mail_Protocol_Exception' with message 'cannot connect to host; error = Connection refused (errno = 111 )' in /home/tchaymor/public_html/gmail/Zend/Mail/Protocol/Imap.php:100 Stack trace: #0 /home/tchaymor/public_html/gmail/Zend/Mail/Protocol/Imap.php(61): Zend_Mail_Protocol_Imap->connect('imap.gmail.com', '993', true) #1 /home/tchaymor/public_html/gmail/three-legged.php(170): Zend_Mail_Protocol_Imap->__construct('imap.gmail.com', '993', true) #2 {main} thrown in /home/tchaymor/public_html/gmail/Zend/Mail/Protocol/Imap.php on line 100 This is my first time using OAuth with any Google products, so it could be something totally brainless I'm missing. Any suggestions would be most welcome (as suggestions for easier alternatives). I'm more on the designer rather than coder end, so the simpler the better.

• SMB access from XP to Windows 2008 R2

  - by Pablo

  Here's the thing... I have a very slow file copy performance from Windows XP clients to Windows 2008R2 servers. Here are the facts: Windows XP to Windows 2K3: Fast Windows XP to Windows 2K8: Very Slow Windows 7 to Windows (any): Fast Despite the fact that the obvious solution would be to upgrade to Windows 7, well, we have 900 desktops so it's not an option in the short time. I have tried everything: Disabling SMB2.0, disabling security signatures, changing the TCP Window size, disabling the W2K8 auto tuning, upgraded the drivers, etc. We eliminated the network; both the server and the client are connected to the same core switch (no hops, no routers, same VLAN). Upon monitoring the network with a packet capture utility, we see that the SMB packets being exchanged between the W2K8 and the XP machines are very small packets (256 bytes); despite the fact that the MTUs are properly set (1500) and there is no fragmentation whatsoever. In fact, those SMB packets show, on the IP datagram, that the window is 65535 or close. The same trace, made using the same application but instead of using a W2K8 share uses a Windows XP share (and that goes FAST) shows SMB packets of 4096 bytes. I can post the traces if necessary. So, why does XP-W2K8 negotiation arrange for 24-bytes SMB payload, whereas the XP-XP negotiation arranges for 4096 SMB packets? Any ideas? I am running short of those...

• Smart card / auditable access for rack KVM tray

  - by Mark Henderson

  Is there such a thing as a KVM Tray for a standard 19" rack whose use can be validated by a smartcard (or some other auditable authentication method)? It looks like we have a security requirement where just because users have a key to the rack doesn't mean they will be allowed to use the console inside the rack, and rather than just lock the console (and keep track of who has keys), we would prefer to be able to audit the actual user that was attached at the KVM. (It's worth mentioning that I'm aware of the Raritan devices, but they surely can't be the only ones) (If these things existed, I don't think half of the tratoirs that somehow manage to infiltrate CTU on the TV show 24 would ever get away with anything)

• Dual NIC internet access

  - by JavaRocky

  Q1. If a computer had two NICs, lets say windows, on which interface would HTTP traffic (or any for that matter) go out on. Not sure how the routes table would look like. Q2. If one of the NICs link becomes unresponsive, would traffic be automatically routed to the other NIC? Thanks.

• MYSQL backup and restore

  - by Codezy

  I am having trouble getting mysql backups to run properly when their are views in the database. I think this might have something to do with needing a placeholder object for it. In any event I run this command: mysqldump -u myuser -pmypassword mydatabase | mysql -u myuser -pmypassword -C mydatabase_Beta The user has full privileges and I get this: View mydatabase_beta.yadayada references invalid tables or columns or functions or definer/invoker or view lack rights to use them. How can I back it up so that it restores all of my database properly? In the example I am restoring it to a different name but I do need to be able to restore a working copy. I think it is probably an additional mysqldump parameter or maybe hot copy would work better. Thoughts?

• Cannot access virtual machine via ping from the physical host machine

  - by Kenni

  I'm installing a FreeBSD Server on VirtualBox. I set up the IP address (192.168.10.5) for the virtual server to run a mail server and the host computer(Windows 7) with 192.168.10.184. The two machines cannot communicate or connect to each other. I cannot ping from the virtual machine to the host and vice versa. The host machine connects to a LAN. I want the mail server to run frm a VMachine. I think it's a problem with the network configuration of the virtual machine.

• Associating multiple data with a single entry in Open Office Base

  - by idyllhands

  I'm trying to build a database that I can use to track prices of groceries on certain dates. My problem is that I cannot figure out how to have a single entry associate with multiple data. For example, carrots. The index would be carrots. Then, a few categorizing fields (ie, Produce|Vegetable) Then, I can enter a price, date that the price was valid, store that was selling for said price, etc. And the next time I buy carrots, I can just add a new set of pricing data that would be associated with the original carrots entry. I know very little about database building, so if anyone has something I could just modify, I would greatly appreciate it. Alternatively, a step by step tutorial would be great.

• Overhead of Perfmon -> direct to SQL Database

  - by StuartC

  HI All, First up, I'm a total newb at Performance Monitoring. I'm looking to set up central performance monitoring of some boxes. 2K3 TS ( Monitor General OS Perf & Session Specific Counters ) 2K8 R2 ( XenApp 6 = Monitor General OS Perf & Session Specific Counters ) File Server ( Standard File I/O ) My ultimate aim is to get as many counters/information, without impacting the clients session experience at all. Including counters specific to their sessions. I was thinking it logging directly to a SQL on another server, instead of a two part process of blg file then relog to sql. Would that work ok? Does anyone know the overhead of going straight to SQL from the client? I've searched around a bit, but havent found so much information it can be overwhelming. thanks

• Slow network file access with VMWare Server and Windows 7

  - by garethm

  I have Windows 7 32-bit virtual machine running in a VMWare Server virtual machine. The host is Windows 7 64-bit. When I copy files between them it is extremely slow - it will take several minutes to copy even a 1 MB file. I can upload the file to an website and then download it again almost instantaneously by comparison. Browsing the network is quite zippy and has no problems. I have been unable to set up a HomeGroup between the computers though - the guest always times out without managing to get setup. Any ideas on how I should go about tracking down where the problem is?
