• Using both domain users and local users for Squid authentication?

  - by Massimo

  I'm working on a Squid proxy which needs to authenticate users against an Active Directory domain; this works fine, Samba was correctly set up and Squid authenticates users via ntlm_auth. Relevant lines in squid.conf: auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 5 auth_param ntlm keep_alive on acl Authenticated proxy_auth REQUIRED http_access allow Authenticated http_access deny all Now, I need a way to allow access to users which don't have a domain account. I know I could create an "internet user" account in the domain, but this would allow access, although limited, to domain resources (file shares, etc.); I need something that will allow only Internet access. The ideal solution would be using a local account on the proxy server, either a Linux account or a Squid one; I know Squid supports this, but I'm unable to have it use both domain authentication and Squid/local authentication if domain auth is unsuccesful. Can this be done? How?

• Storing data for use on Android and Windows Applications

  - by Andy Mepham

  I posted this last night on StackOverflow and was advised to move it over to StackExchange, thank you for taking a moment to look at my question. I'm developing a project proposal for my final year project at University and as I aim to use programming languages I am currently not too familiar with I'm looking for some guidance - I can't include details of my project but hopefully you will understand what I'm after. I'm going to be creating an Android application (in Java) and a Windows Application (in C#) that will ideally access, query and update a remotely hosted Database or set of XML files (this would most likely be over the Internet). I've done some looking around the internet and SQLite seems like a safe-bet for cross-platform manipulation of the database; however I would like to keep the system as lightweight as possible and I'm wondering whether XML files may provide a better alternative? Anyone out there that has experience using SQLite and/or remotely hosted XML for the purposes of Android and/or C# development that could point me in the right direction? If there is an alternative solution other than those I have mentioned I would be interested to hear about them too. Thank you for taking the time to read my question. Edit: The purpose of this application is for a small scale business, the data source would not need to be updated by more than one source but may be view from multiple sources (i.e. through multiple phones and a desktop PC). The database wouldn't be updating masses of data at a time (most likely single rows of a few tables at the most).

• Monitoring ASA packet loss via SNMP

  - by dunxd

  I want to monitor packet loss on my ASA 5505 VPN endpoints using SNMP. This is so I can graph the rates in Cacti and/or get alerts in Nagios. However, I am not sure what SNMP values I should use to measure packet loss. In the ASA I can run sh interface Internet stats to show traffic statistics for the interface connected to the Internet. This shows 1 minute and 5 minute drop rates. Are these measures an indicator of packet loss? Are there SNMP values I can access that correspond to those values? Should I be looking at different values? Is the ASA even able to measure packet loss?

• Blank screen after GRUB (64 bit) - cannot install Ubuntu

  - by peGGi

  My laptop's specs: Lenovo IdeaPad Z570 Intel Core i5-2410M @ 2.3Ghz 6 Gb RAM DDR3 640 Gb ATAPI Hard-disk Drive @ 5,200 RPM NVIDIA GeForce G520M with Optimus switching technology Broadcom 802.11n Network Adapter REALTEK soundcard Windows 7 Home Premium 64-bit I downloaded Ubuntu Studio 11.04 and burned the iso image onto two different DVDs, using two different programs (one DVD is RW, the other is just R). I verified the hash MD5sum thing. I get as far as GRUB with the 4 options (install, advanced install, disk verification, system rescue) but no matter which one I select, I get a blank screen and nothing happens. The DVD drive spins down after about 30 seconds. Also just before the GRUB screen I get a message saying Error: "Prefix" is not set. I'm not sure if that's relevant. I have tried all the options using both DVDs. Same thing happens. I have changed the graphics setting in BIOS to UMA or Optimus, but still happens either way. I've tried booting with the wireless switch turned off, same thing happens. I downloaded 'vanilla' Ubuntu 64-bit and burned onto a CD, and the same thing happens. I have downloaded Ubuntu 32-bit and I am able to boot from the live CD (interestingly the wireless card won't work, but that's maybe another issue). I have searched extensively through these forums and other sites but I can't see anything that will help me. Is there something I'm missing? I'd really appreciate help on this. The laptop is less than 2 weeks old. I was so looking forward to getting Ubuntu Studio up and running. I've gone about as far as my technical abilities will allow.

• Using PowerShell, in Active Direcotry, how would I change all the DNS A records that have a given IP to a new IP?

  - by djsumdog

  We've been moving data centers and I have a lot of old records that were not correctly but in DNS as CNAME records, but A records that have a direct IP (e.g. 192.168.100.n) and they're all moving to a new subnet (10.19.100.n). I just need to write a powershell script to change all those records. I found this site: http://www.indented.co.uk/index.php/2008/12/30/administering-microsoft-dns-in-powershell/ and from it I made this simple script: $dnsServer = "meldc2" $scope = New-Object Management.ManagementScope("\\$dnsServer\root\MicrosoftDNS") $path = New-Object Management.ManagementPath("MicrosoftDNS_Zone") $options = New-Object Management.ObjectGetOptions($Null,[System.TimeSpan]::MaxValue, $True) $ZoneClass= New-Object Management.ManagementClass($scope,$path,$options) $Zones = Get-WMIObject -Computer $dnsServer -Namespace "root\MicrosoftDNS" -Class "MicrosoftDNS_Zone" $Zones | Get-Member foreach($Z in $Zones) { $Z | Select-Object Name,DsIntegrated,ZoneType,Reverse,Data } but that only gets me a listing of root zones. I don't understand how to iterate over all the entries in each of the zones. Also, all the examples I've seen involve adding new zones, but there aren't any examples I can find on modifying existing A records.

• Multisession burn in Imgburn

  - by blntechie

  Is Multisession burn available in Imgburn? If not, any idea whether it will be implemented in future? I almost recommended Imgburn instead of Nero or Roxio to one of my friend. He requires multisession burning and I found no options to enable it,if available in Options. Note: Please don't question the question. Like, Why would you want multisession anyway? or Isn't USB stick/RW Disk is what you need instead of a RO CD/DVD? Please keep the answers in context. I know that I can use USB sticks instead of CD/DVD and my friend require mulisession anyway. May be I can ask him to keep Nero as a backup for this purpose if Imgburn don't support this.

• Change popup format for Kopete in Gnome (Ubuntu 10.04)

  - by HorusKol

  After trialling Empathy which was included with Gnome/Ubuntu 10.04 I decided to go back to Kopete since I was losing chat messages. However, for some reason, Kopete is now displaying all popups in a big, ugly window with four options (ok, cancel, view, ignore, or something like that) that actually all seem to do nothing. I tried looking for options in Kopete to change the popup style to the nicer Gnome style one which goes up in the top-right of my desktop, but it doesn't seem to be possible with this release. So I had to resort to removing all popup messages from Kopete to prevent my screen being taking over by a popup requiring action for every incoming chat message. Unfortunately, this now means that I do not get any notifications when people message me - and so I can go a couple of hours without realising that they did. Anyone know how to get the nice, unobtrusive popups working in this version?

• Wired and wireless conections: force Windows to connect to laptop through Ethernet?

  - by danielkza

  I have a desktop connected to the internet and to my home network through Wi-Fi, and a latptop connected to said desktop through an Ethernet cable. But Windows seems to only reach the laptop through Wi-Fi: I want to transfer files through the wired connection instead. Setting up Internet Connectin Sharing and disconnecting the laptop from Wi-Fi altogether doesn't seem like the most elegant solution to me. I also thought about going to the hosts file and setting up the IP address manually, but that would make the laptop completely unavailable if it's not wired, which happens quite often unfortunately. Is there any way for me to tell Windows to use the wired connection for a particular host if possible, and fallback to any other route it finds otherwise?

• Click and Drag from Clickpad stops working after a while 12.04

  - by Jason O'Neil

  I've got a Samsung Notebook (NP-QX412-S01AU) with a touchpad / clickpad. I'm running 12.04 Precise. When I first log into my computer, the touchpad behaves exactly as expected and desired. The longer I stay logged in, it slowly degrades. I'll try describe it. There are 3 ways of "dragging" on this clickpad: (Physical) click and hold with one finger, and drag around while still holding it down. All with one finger. (Physical) Click and hold with one finger, then with another finger drag around to move cursor. Double tap (not a physical click) and on the second tap, hold and drag. I most naturally use option 1, but here's how it works: When I first turn on, options 1, 2 and 3 all work. After a while, only options 2 and 3 work. Later still, only option 3 works. Restarting X causes all 3 to work again. I've compared the output of "synclient" in each of the states, and there was no difference. Anybody know what to look at? Or at the very least, a command I can run to "restart" the mouse driver without restarting X?

• SVN Server not responding

  - by Rob Forrest

  I've been bashing my head against a wall with this one all day and I would greatly appreciate a few more eyes on the problem at hand. We have an in-house SVN Server that contains all live and development code for our website. Our live server can connect to this and get updates from the repository. This was all working fine until we migrated the SVN Server from a physical machine to a vSphere VM. Now, for some reason that continues to fathom me, we can no longer connect to the SVN Server. The SVN Server runs CentOS 6.2, Apache and SVN 1.7.2. SELinux is well and trully disabled and the problem remains when iptables is stopped. Our production server does run an older version of CentOS and SVN but the same system worked previously so I don't think that this is the issue. Of note, if I have iptables enabled, using service iptables status, I can see a single packet coming in and being accepted but the production server simply hangs on any svn command. If I give up waiting and do a CTRL-C to break the process I get a "could not connect to server". To me it appears to be something to do with the SVN Server rejecting external connections but I have no idea how this would happen. Any thoughts on what I can try from here? Thanks, Rob Edit: Network topology Production server sits externally to our in-house SVN server. Our IPCop (?) firewall allows connections from it (and it alone) on port 80 and passes the connection to the SVN Server. The hardware is all pretty decent and I don't doubt that its doing its job correctly, especially as iptables is seeing the new connections. subversion.conf (in /etc/httpd/conf.d) LoadModule dav_svn_module modules/mod_dav_svn.so <Location /repos> DAV svn SVNPath /var/svn/repos <LimitExcept PROPFIND OPTIONS REPORT> AuthType Basic AuthName "SVN Server" AuthUserFile /var/svn/svn-auth Require valid-user </LimitExcept> </Location> ifconfig eth0 Link encap:Ethernet HWaddr 00:0C:29:5F:C8:3A inet addr:172.16.0.14 Bcast:172.16.0.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe5f:c83a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:32317 errors:0 dropped:0 overruns:0 frame:0 TX packets:632 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2544036 (2.4 MiB) TX bytes:143207 (139.8 KiB) netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 1484/mysqld tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1135/rpcbind tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1351/sshd tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN 1230/cupsd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1575/master tcp 0 0 0.0.0.0:58401 0.0.0.0:* LISTEN 1153/rpc.statd tcp 0 0 0.0.0.0:5672 0.0.0.0:* LISTEN 1626/qpidd tcp 0 0 :::139 :::* LISTEN 1678/smbd tcp 0 0 :::111 :::* LISTEN 1135/rpcbind tcp 0 0 :::80 :::* LISTEN 1615/httpd tcp 0 0 :::22 :::* LISTEN 1351/sshd tcp 0 0 ::1:631 :::* LISTEN 1230/cupsd tcp 0 0 ::1:25 :::* LISTEN 1575/master tcp 0 0 :::445 :::* LISTEN 1678/smbd tcp 0 0 :::56799 :::* LISTEN 1153/rpc.statd iptables --list -v -n (when iptables is stopped) Chain INPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination iptables --list -v -n (when iptables is running, after one attempted svn connection) Chain INPUT (policy ACCEPT 68 packets, 6561 bytes) pkts bytes target prot opt in out source destination 19 1304 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 0 0 ACCEPT icmp -- * * 0.0.0.0/0 0.0.0.0/0 0 0 ACCEPT all -- lo * 0.0.0.0/0 0.0.0.0/0 0 0 ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 1 60 ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:80 0 0 ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:80 0 0 ACCEPT udp -- * * 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:80 Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 17 packets, 1612 bytes) pkts bytes target prot opt in out source destination tcpdump 17:08:18.455114 IP 'production server'.43255 > 'svn server'.local.http: Flags [S], seq 3200354543, win 5840, options [mss 1380,sackOK,TS val 2011458346 ecr 0,nop,wscale 7], length 0 17:08:18.455169 IP 'svn server'.local.http > 'production server'.43255: Flags [S.], seq 629885453, ack 3200354544, win 14480, options [mss 1460,sackOK,TS val 816478 ecr 2011449346,nop,wscale 7], length 0 17:08:19.655317 IP 'svn server'.local.http > 'production server'k.43255: Flags [S.], seq 629885453, ack 3200354544, win 14480, options [mss 1460,sackOK,TS val 817679 ecr 2011449346,nop,wscale 7], length 0

• Why are my Photoshop modify selection tools graying out?

  - by Myersguy

  So, I looked into this a little before asking. Basically, I always select the entire canvas, and modify my selection for multiple Photoshop effects. It has never given me problems until just recently. Now, if I select the entire canvas, Photoshop will gray out the modify selection options. People online claimed that you can't select the entire canvas, but that is how I've been doing it for years. So, does anyone know how to stop the selections from graying out? I don't want to have to expand my canvas each time I want to create borders, etc. I need a work around, a method, anything that will stop these options from graying out like they currently are. Thanks.

• Using Quickly for text-heavy app

  - by Kevin

  I am trying to create a small app that displays documentation. When it is run, the application window will display a main menu with buttons labeled 'Document 1', 'Document 2', etc. If a user clicks on one of those buttons, the text from the corresponding document will be displayed in the window. Very basic. The text documents range in length from 1000 to 5000 words, and they need basic formatting (bold, italic, maybe one or two font choices). My question is this: what is the best way to store and display long blocks of formatted text, using Quickly? There seems to be a few options: (1) I could load the text blocks into long python strings, (2) I could load the text from text files, or (3) I could somehow copy and paste the formatted text into Glade. In the first two options, I'm not sure how I would format the text (add italic and bold, for instance) once it was loaded. I have experience with PHP/MySQL/HTML/CSS/Javascript, but I'm new to Python. Any help would be appreciated.

• Design mode in Visual studio 2010 sp1 beta

  - by anirudha

  in MVC3 razor we found that their is no way to watch the design in Visual studio as well we can see aspx file by going to design mode. their is a little trick to solve this issue first is that if you have Expression web or Vs 2008 then open the file on them how see here in expression web 4 you need to add the extension .cshtml and open them as html as we open other. in Visual studio 2008 you need to add the extension .cshtml and set them open as html. well their is no big trouble if design not worked. but in some case when you need to get this issue solved this need to be work for configuration do this: Expression Web 4 > tools > application options > configure editor > click on new extension icon show in exact left put the cshtml in the window they show you and choose expression web [open as html] after that you can see the design in expression web. by default Expression web not have cshtml as known extension so you need to do that to add them because without it they never handle cshtml file and refer them to Visual studio. after setting this you  EW4 open the cshtml file as html and show you design in design mode. in Visual studio 2008 you can use same trick to solve this issue just follow this step > options > text editors > file extension put cshtml in textbox and set the option html editor from dropdown and click on add and ok this will open your cshtml file as html.

• SSH to an ubuntu machine using avahi

  - by tensaiji

  I have an ubuntu box that I connect to using avahi. Connecting to that box works fine for all services (I regularly use AFP, SSH and SMB on it) but I've noticed that whenever I connect to it from a mac using SSH (and using the ".local" dns name provided by avahi - eg. "ssh .local") SSH tries to connect using ipv6, which for some reason times out (after two minutes) then it tries ipv4 which connects immediately. I'd like to avoid this timeout, as it's really annoying for me and other users - if SSH tried ipv4 first or if ssh over ipv6 worked then that would solve the problem. But so far I've been unable to get either to work (the best I've managed is to specify the "-4" option to SSH to stop it from trying ipv6 at all). I'm using Ubuntu 10.04. Any solution has to be on the server (not the client) as there are multiple clients connecting. A possible complication might be that my LAN is set up to allow link-local ipv6 addresses only, but I have other servers (using Mac OS) that I can SSH into using ipv6) I suspect that the problem could be solved by either preventing avahi from broadcasting the ipv6 address, or by enabling ssh over ipv6, but so far as I can tell avahi is already configured not to broadcast the ipv6 address and sshd is configured to allow ipv6 connections! Here's my /etc/avahi/avahi-daemon.conf (I don't think I've changed anything from the ubuntu defaults) [server] #host-name=foo #domain-name=local #browse-domains=0pointer.de, zeroconf.org use-ipv4=yes use-ipv6=no #allow-interfaces=eth0 #deny-interfaces=eth1 #check-response-ttl=no #use-iff-running=no #enable-dbus=yes #disallow-other-stacks=no #allow-point-to-point=no [wide-area] enable-wide-area=yes [publish] #disable-publishing=no #disable-user-service-publishing=no #add-service-cookie=no #publish-addresses=yes #publish-hinfo=yes #publish-workstation=yes #publish-domain=yes #publish-dns-servers=192.168.50.1, 192.168.50.2 #publish-resolv-conf-dns-servers=yes #publish-aaaa-on-ipv4=yes #publish-a-on-ipv6=no [reflector] #enable-reflector=no #reflect-ipv=no [rlimits] #rlimit-as= rlimit-core=0 rlimit-data=4194304 rlimit-fsize=0 rlimit-nofile=300 rlimit-stack=4194304 rlimit-nproc=3 and here's my sshd_config (mainly updated to only allow pub/private keys): # What ports, IPs and protocols we listen for Port 22 # Use these options to restrict which interfaces/protocols sshd will bind to #ListenAddress :: #ListenAddress 0.0.0.0 Protocol 2 # HostKeys for protocol version 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key #Privilege Separation is turned on for security UsePrivilegeSeparation yes # Lifetime and size of ephemeral version 1 server key KeyRegenerationInterval 3600 ServerKeyBits 768 # Logging SyslogFacility AUTH LogLevel INFO # Authentication: LoginGraceTime 180 PermitRootLogin no StrictModes yes RSAAuthentication yes PubkeyAuthentication yes #AuthorizedKeysFile %h/.ssh/authorized_keys # Don't read the user's ~/.rhosts and ~/.shosts files IgnoreRhosts yes # For this to work you will also need host keys in /etc/ssh_known_hosts RhostsRSAAuthentication no # similar for protocol version 2 HostbasedAuthentication no # Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication #IgnoreUserKnownHosts yes # To enable empty passwords, change to yes (NOT RECOMMENDED) PermitEmptyPasswords no # Change to yes to enable challenge-response passwords (beware issues with # some PAM modules and threads) ChallengeResponseAuthentication no # Change to no to disable tunnelled clear text passwords PasswordAuthentication no AllowGroups sshusers # Kerberos options #KerberosAuthentication no #KerberosGetAFSToken no #KerberosOrLocalPasswd yes #KerberosTicketCleanup yes # GSSAPI options #GSSAPIAuthentication no #GSSAPICleanupCredentials yes X11Forwarding yes X11DisplayOffset 10 PrintMotd no PrintLastLog yes TCPKeepAlive yes #UseLogin no MaxStartups 10:30:60 #Banner /etc/issue.net # Allow client to pass locale environment variables AcceptEnv LANG LC_* Subsystem sftp /usr/lib/openssh/sftp-server UsePAM yes Does anyone have any ideas that I can try, or has experienced anything similar?

• PC will be turned off in safe mode

  - by abbasi

  I wanted to scan a Dell inspiron N5010 laptop in safe mode. When I took it to the safe mode environment and ran the AV to scan, after some while the PC went out! The power options menu options (when plug is in) are as follows: Screensaver after 4 mins. Dim to display after 10 mins. Turn off display after 15 mins. Hard disk, sleep and hibernate are all off (set to never). I tested the machine without scanning it, i.e, went to the safe mode and waited to see what occurs after time elapsing. By observations so far (because I can apply more tests to determine that where the problem exactly is), the problem is when the machine is in safe mode and is doing something (in current case, scanning). What do you think? Why it goes out in this situation please? Thanks in advance.

• Why does mod_security require an ACCEPT HTTP header field?

• How to make a DHCP server on virtual machine serves other virtual machines(on different physical machines)?

  - by Tony

  I'm building a virtual cluster with VirtualBox and Opensuse. I have 10 physical machines and need several vms on each. The virtual machines are supposed to be in a "private" network, but still have internet access. I was asked to set up a virtual head node working as DHCP server. I installed DHCP server on the virtual head node and it seems works. On VirtualBox I set 2 network adapters to the head node, one bridged adapter and one internal network. One vm on the same physical machine has been set nic as internal network adapter. The vm can get IP address (so DHCP works) but can't access internet. What should I do? Specifically, what network adapter should I choose for head-node and work-nodes in VirtualBox? What in the virtual machines should I do?

• Domain changes required for SSL integration

  - by user131003

  Currently my site supports regular payment options (User is taken to Payment Gateway/PG website). Now I'm trying to implement "seamless" PG integration. I need SSL for this. I'm having a dedicated server with 5 static IPs from Hostgator/HG. options: I take SSL for www.my_domain.com. According to HG, I need to change IP of main site as current IP is not really dedicated as it is being shared by cpanel etc. So They need to bind another dedicated IP to main domain for SSL to work. This would required DNS change for main website and hence cause few hours downtime (which is ok). I've noticed that most of the e-commerce websites are using subdomains like secure.my_domain.com for ssl/https. This sounds like a better approach. But I've got few doubts in this case: a) Would I need to re-register with existing PGs (Paypal, Google Checkout, Authorize.net) if I switch to subdomain? Re-registering is not an option for me. b) Would DNS change be required for www.my_domain.com in this case. This confusion arose because of following reply from HG : "If the sub domain secure.my_domain.com is added to an existing cPanel it will use the IP for that cPanel so as long as it is a Dedicated IP that will be fine. If secure.my_domain.com gets setup as its own cPanel it will need to be assigned to a Dedicated IP which would have a DNS change involved.". Please suggest?

• Why is my NTP controlled computer clock two minutes ahead?

  - by Martin Liversage

  The clock in my computer is configured to be synchronized using NTP. To verify this I have tried two NTP clients using various NTP servers. My computer and the NTP clients are in complete agreement about the current time even across a wide range of NTP servers. I also have a GPS and my national phone company provides an accurate clock available by calling a specific phone number. Both my GPS and the phone company agrees on the current time. However, my computer is almost precisely two minutes (or 1 minute and 59 seconds) ahead of what I believe to be the "real" current time where I live. Why is my computer two minutes ahead? I realize that synchronizing clocks using the internet may not be entirely accurate as there is latency, but two minutes is a very long time on the internet. Is NTP really two minutes ahead? I'm running Windows 7 and live in the time zone UTC+1, but I don't think that is important in understanding my problem.

• Program broke my windows. Everything randomly minimizes even after multiple restarts

  - by Xitcod13

  I just installed LoL (league of legends) on my computer. The problem is that almost every time after I play the game, it minimizes all my windows which is really annoying. What is worse however is that afterwards other programs do this as well. In the internet browser doesn't minimize but it does loose focus. For example when i type it randomly looses focus and i have to click on the browser window again to it registers my typing. Is there any way to fix this? What can cause such a strange behavior?? In addition this problem persists even after restarting my computer. I previously thought it was internet driver. I no longer think so this happened right after I started playing the game and seems pretty persistent. Please read the comments for further information. This pretty much renders my computer useless. Even typing this takes a huge effort.

• Legal issues regarding embedding a toolbar into a browser [closed]

  - by OmarOthman

  We are in the process of developing a software that provides service to internet users and we would like to ask about the legal liabilities of some issues. Of course, everything is to be done with the consent of the user of our software but our concern is about third party tools and services that may be invoked/used by our product. In particular, these are the concerns: (1) Embedding a toolbar to an existing browser. This screenshot is an example, where the words in the highlighted toolbar are passed to www.google.com for searching, and the contents of the window are the results of the search. I want to know if any consent should be obtained before such a toolbar can be embedded in a web browser, whether there are any legal requirements by the web browser; whether different web browsers have different requirements (at least for Internet Explorer, Firefox, Chrome, Opera and Safari). (2) Invoking a free website from that toolbar (like Google’s search page). The screenshot above demonstrates such an existing toolbar. (3) Full ownership and unrestricted access to the data entered to this toolbar. In the screenshot above, I want to take the words (translation english to spanish) and own them, i.e. storing them in my database and do some processing on them. (4) Ability to track the pages entered by the user starting from that free website. In the screenshot above, you can notice that the user opted only for the third result, whose URL is translate.google.com. I want to have access to this and all URLs clicked from this page for some processing as well. This is a commercial application, so I need a very concrete, precise and reference-supported answer.
