• 85 Hz on old/new driver looks the same like 75 Hz on previous one?

  - by jon

  I have old philips 107T5 CRT and Nvidia graphics card. I used old Nvidia driver (but it wasn't 'legacy' one when I installed it) for few years but recently I decided to install other Linux distribution. I used 75 Hz refresh rate and 1024x768 resolution on my previous distribution. After I installed the new distribution I had to install a Nvidia driver so I downloaded one from the Nvidia site (this time only legacy supported my card so I downloaded legacy and installed it). It wasn't automatically updating xorg.conf but I had my previous xorg.conf copy and I used it. When I run X I could only choose 85 and 75 Hz, 85 was checked as default. And now what shocks me: that default 85 Hz looks identically like 75 Hz on previous driver looked (at least to me). I tried 75 Hz out of curiosity and it's too bright, hurts, etc. But on the previous driver 75 Hz wasn't hurting my eyes. Why is it different? It's the same number after all, so it should always give the same results, right? That's my first question. Second question: Is 85 Hz OK for that monitor model? Would it break it? I tried to find the optimal refresh rate for this model but couldn't find it.

• .htaccess with addondomain and https ssl

  - by admon

  I have main domain and addon domain. Question. 1)When surfing to: ftp.addondomain.com or mail.addondomain.com For some reason it goes to the main domain. (normally this should not be problem but i still want completely separation) Do you know the syntax to redirect in the .htaccess file this: (.*).addondomain.com - addondomain.com and where do i put the code? in the addondomain .htaccess or in the main domain attaccess I.E any_words.addondomain.com should be forwarded to the addondomain.com so these: dsdhf.addondomain.com ftp.addondomain.com mail.addondomain.com ... all will be forwarded to: addondomain.com (i.e without the prefix). 2)Same question for https:// Main domain has SSL addon domain does not have ssl. For some reason when surfing to: https:// addondomain.com you get to: http:// maindomain.com (the address bar shows https:// addondomain.com but the site pages - the page you see is the page of the main domain) I would like that if user surfs to https:// addondomain.com then (since there is no ssl for the addon domain) then user will get to: http:// addondomain.com Or alternatively user will get error message. I do not want him to be redirected to the main domain. Please if you can, write me what to add to the .htaccess and i will add it. Please also let me know where to write the code. I.E in the addondomain .htaccess or in the main domain attaccess Thanks.

• Outbound ports to allow through firewall - core requirements

  - by dunxd

  This question was asked before, but in a rather general way. I'm asking more specifically based on my current requirements. We have a number of remote offices made up of a bunch of PCs and an ASA 5505 which is used as firewall and VPN termination point. In the offices we share the internet connection with one or more other organisations over whom we have very little control, asides from the config on the ASAs. For a bunch of reasons I'd like to lock down these ASA 5505s to only allow outbound traffic to ports used by applications we know we need. I'm putting a standard config to roll out to all the ASAs, and if we need to open up ports for the other orgs we can do it on request. But I want to leave open the most commonly required ports so we can get up and running without waiting on other folks technical staff to get back. I plan to allow the following TCP ports to support email and web access, which I know everyone will need: POP3 (110 and 995) HTTP (80 and 443) IMAP4 (143 and 993) SMTP (25 and and 465) The question really is, what other ports do I need to leave open to allow for "normal" working? I've seen UDP port 53 for DNS as one. Are there any others that would be worth opening up? Just to note - I'll also be setting up monitoring systems to keep an eye on the ports we do allow. Any of the above could be misused of course. We'll also back all this up with signed agreements. But I'm aiming for a technical solutions where I don't have to start out with the full requirements of everyone we share connections with. See also: outbound ports that are always open

• Can SQL Server (2008) transaction logs handle the database being dropped and re-created?

  - by Ben

  We're trying to restore a database (created programatically by running a hand-crafted SQL script we have). Our backup routine is to create a full backup of every database on the SQL Server 2008 instance on a Saturday then automatic transaction logs (I assume these are created automatically anyway - we appear to have lots of log files, possibly one per transaction after the full backup was taken?). On Tuesday this week the database in question was dropped and another one with the exact same name and schema was created. SQL Server has continued to create transaction log files but it hasn't had chance to create a new full backup (that won't happen until next Saturday). Now as it turns out we need to restore the database to how it was on Thursday. This is after the "drop and re-create". My question is, is this possible? If it isn't, what exactly does SQL Server think that it's writing to those transaction logs created since the drop and re-create? (I understood they were kind of files containing a binary delta, which makes me think maybe we can restore from them?) I'm no DBA but then neither is our IT department, so I'm doing the best I can to resolve this. Any advice much appreciated!

• How intrusive is using VPN?

  - by Slade

  My company lets us work from home sometimes using VPN (during weather emergencies and stuff). When logging in a big window comes up that says the network is private and for employees only and that there's no right to privacy while using VPN. It makes sense that they don't want people poking around their network but I wonder if the company can use the connection to look around my computer while I'm connected. I'm not entirely computer-illiterate but I'm not a networks person at all so the technical documents I've found don't help me. Is that possible, and if so to what degree? UPDATE Thanks Mark. The funneling thing is what I was really asking about. Mostly I was worried that I would already have some IM conversation open or log into eBay forgetting that the VPN was open and that my company IT people would see it or that they would log my eBay password. Thanks again. ANOTHER UPDATE What if my son wants to play online poker or Warcraft etcetera while I have VPN on to work? Can my company think I'm the one playing if I am not typing often?

• Virtual Host Configuration and mod_rewrite - Removing PHP Extension and Adding Forward Slash

  - by nicorellius

  On my production server, things are fine: PHP extension removal and trailing slash rules are in place in my .htaccess file. But locally, this isn't working (well, partially, anyway). I'm running Apache2 with a virtual host for the site in question. I decided to not use the .htaccess file in this case and just add the rules to the httpd-vhosts.conf file instead, which, I've heard, if possible on your server, is a better way to go. The virtual host is working and the URL I use for my site is like this: devserver:9090 Here is my httpd-vhosts.conf file: NameVirtualHost *:9090 # for stuff other than this site <VirtualHost *:9090> ServerAdmin admin@localhost DocumentRoot "/opt/lampstack/apache2/htdocs" ServerName localhost </VirtualHost> # for site in question <VirtualHost *:9090> ServerAdmin admin@localhost DocumentRoot "/opt/lampstack/apache2/htdocs/devserver" ServerName devserver <Directory "/opt/lampstack/apache2/htdocs/devserver"> Options Indexes FollowSymLinks Includes AllowOverride None Order allow,deny Allow from all </Directory> <IfModule rewrite_module> RewriteEngine ON # remove PHP extension and add trailing slash # note - this doesn't work for directories, and throws 404 # TODO - fix so directories use index.php RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{THE_REQUEST} ^GET\ /[^?\s]+\.php RewriteRule (.*)\.php$ /$1/ [R=302,L] RewriteCond %{REQUEST_FILENAME} !-d RewriteRule (.*)/$ /$1.php [L] RewriteCond %{REQUEST_FILENAME}.php -f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .*[^/]$ /$0/ [R=302,L] </IfModule> # error docs ErrorDocument 404 /errors/404.php </VirtualHost> The problem I'm facing is that when I go to directories on the site, I get a 404 error. So for example, this: devserver:9090/page.php goes to devserver:9090/page/ but going to a directory (that has an index.php): devserver:9090/dir/ throws 404 error page. If I type in devserver:9090/dir/index.php I get devserver:9090/dir/index/ and the contents I want appear... Can anyone help me with my rewrite rules?

• When using software RAID and LVM on Linux, which IO scheduler and readahead settings are honored?

  - by andrew311

  In the case of multiple layers (physical drives - md - dm - lvm), how do the schedulers, readahead settings, and other disk settings interact? Imagine you have several disks (/dev/sda - /dev/sdd) all part of a software RAID device (/dev/md0) created with mdadm. Each device (including physical disks and /dev/md0) has its own setting for IO scheduler (changed like so) and readahead (changed using blockdev). When you throw in things like dm (crypto) and LVM you add even more layers with their own settings. For example, if the physical device has a read ahead of 128 blocks and the RAID has a readahead of 64 blocks, which is honored when I do a read from /dev/md0? Does the md driver attempt a 64 block read which the physical device driver then translates to a read of 128 blocks? Or does the RAID readahead "pass-through" to the underlying device, resulting in a 64 block read? The same kind of question holds for schedulers? Do I have to worry about multiple layers of IO schedulers and how they interact, or does the /dev/md0 effectively override underlying schedulers? In my attempts to answer this question, I've dug up some interesting data on schedulers and tools which might help figure this out: Linux Disk Scheduler Benchmarking from Google blktrace - generate traces of the i/o traffic on block devices Relevant Linux kernel mailing list thread

• Role of MBR in the booting process

  - by pg4421

  I am new to stack overflow. So please correct me if my question seems irrelevant or stupid. I read here in Booting Process : The job of the primary boot loader is to find and load the secondary boot loader (stage 2). It does this by looking through the partition table for an active partition. When it finds an active partition, it scans the remaining partitions in the table to ensure that they're all inactive. When this is verified, the active partition's boot record is read from the device into RAM and executed. The question is that I am having a Hard disk which has two Operating System images windows and ubuntu and hence both partitions in which they reside are active. Then why do we have only one active partition always? (I know that active partition is one of the primary partition but then why we are giving special reference to one primary partition? ) I am confused a bit. Please solve my query. Thank you so much.

• SBS 2008 Sharepoint Database good Memory Limit.

  - by ldelgado

  I manage a small network running on Small Business Server 2008. Lately, the Sharepoint embedded database is getting out of control with its memory usage. I've got a total of 16 GB of RAM on this server, and the Sharepoint database sometimes uses almost 8 GB of RAM. This never happened before, and it started happening after I installed Backup Exec 2010. It happens after a backup is performed. So I suspect there is a memory leak involved. I am working on that issue, but this question isn't about that. I would like to limit the amount of memory the Embedded database uses. I know how to do it. My question is, what would be the ideal amount of memory that I can allocate to Sharepoint? There are only 4 users on my network. One of the users uses two computers but not at the same time. They use sharepoint for a company calendar, and sometimes they share files that way also. Let me know if you need to know anything else. Thanks,

• VMWare Server modifying files related to paused VMs, is this expected?

  - by David Spillett

  While refreshing the backup of a VM used for testing, I experienced the following warning from tar: tar: /VMsR0/cli_noddyco_test/VM2K8_32_web.vmem: file changed as we read it The VMs in question were paused at the time. My first though was that I'd mixed up the machines and was trying to backup something that was still actively running. To be sure I unpaused and properly shut down the VM, and the vmem files that tar reported changing vanished as I would expect. Is it normal for VMWare Server to touch or alter files for paused VMs like this, or is there likely something amiss with our setup? If this is expected behaviour, is just touching the vmem file (and so altering the last modification date without actually changing content)? If it is normal for files relating to paused VMs to be updated I shall have to revise our backup procedures to make sure the VMs are fully shut down fully rather than just pausing them (this isn't a problem, but it seems strange and I'd prefer to understand what VMWare is doing and why instead of just dismissing it as "one of those things" and working around it). For further detail: the host in question is VMWare Server version 2.0.2 running on 64-bit Debian/Lenny, and that VM did not have a snapshots at the time. We have backed up paused VMs this way in the past with no such warnings from tar.

• powershell vs GPO for installation, configuration, maintenance

  - by user52874

  My question is about using powershell scripts to install, configure, update and maintain Windows 7 Pro/Ent workstations in a 2008R2 domain, versus using GPO/ADMX/msi. Here's the situation: Because of a comedy of cumulative corporate bumpfuggery we suddenly found ourselves having to design, configure and deploy a full Windows Server 2008R2 and Windows 7 Pro/Enterprise on very short notice and delivery schedule. Of course, I'm not a windows expert by any means, and we're so understaffed that our buzzword bingo includes 'automate' and 'one-button' and 'it needs to Just Work'. (FWIW, I started with DEC, then on to solaris and cisco, then linux of various flavors with a smattering of BSD nowadays. I use Windows for email and to fill out forms). So we decided to bring in a contractor to do this for us. and they met the deadline. The system is up and mostly usable, and this is good. We would not have been able to do this. But it's the 'mostly' part that is proving to be the PIMA now, and I'm having to learn Microsoft stuff anyway until/if we can get a new contract with these guys for ongoing operations. Here's my question. The contractor used powershell almost exclusively for deployment, configuration and updating. My intensive reading over the last week leads me to think that the generally accepted practices for deployment, configuration and updating microsoft stuff uses elements of GPOs and ADMX templates, along with maybe some third party stuff like PolicyPak. Are there solid reasons that I've not found yet that powershell scripts would be preferred over the GPO methods? I'm going to discuss this with the contractor lead when he gets back from his vacation, and he'll be straight with me (nor do I think they set us up). But I can also see this might be a religious issue, so I would still like some background on this. Thoughts? or weblinks? Thanks!

• Is there an Installer Analyser tool that can list what Registry Keys will be created?

  - by EvoGamer

  I can think of 3 ways to achieve my goal: Create a clean VPC, install a given piece of software, and compare the before and after states. Somehow reverse-engineer the installer. Somehow redirect the output of the installer in question so that all registry calls and copy/move file commands are recorded, but not executed. The first option can be done manually, or potentially automated, but I feel it's rather OTT for my needs. The second could cause all sorts of licencing issues, not to mention it may not always return a correct result. Also, without delving into hex editing, I can't think of a way that it would be possible to do manually (some installers - eg Anti-Virus software - may react unfavourably on automated attempts to investigate the installer). The third option shows the most promise, although if the first could be stripped down into a lightweight throwaway environment, it would work pretty much the same way. However, I'm not sure how to do it. So my question is: What tools are available (if any) and/or how could I find out this information manually? I'm not looking to reverse-engineer anything (if I can help it), but I just want to know exactly what changes are being made to my PC by a given piece of software.

• Changing the View of a Folder When It Is Opened from Finder

  - by user60044

  When I was running OS 10.4 I had all my folders beautifully organized with position and which ones should be opened in View mode and which one in Icon, etc. When I transitioned to 10.6 I found that OS ignored all that information and imposes an awful consequence of changing the view for some folder and that view moving up to all parent folders which don't have their views locked. The only way I can think of to get this functionality back is to either write a program that given a root directory will enumerate it setting the views based upon a static template I have. The other way I thought I could accomplish this is by Folder Actions. Aside from the fact that I don't know AppleScript it seems folder actions cannot be inherited. Since I have 1000s of folders involved here, all being inherited from a single root, I could not possibly manually add that action to each of those folders. What I would like to have is a folder action that whenever I open the folder from Finder, then if it contains any JPG, GIF, etc. type image files that it will automatically open that folder with a view of Icon with a reasonable size to support the number of images. If the folder contains only folders, then to open that folder in the list view. Does anyone have anything that could do this for me? Thank You, -- Mark

• Stop Windows 7 from accessing or writing to hard drive unless "told" to by me? (More info inside...)

  - by Jeff

  A confusing question, perhaps, but bear with me. I have two internal HDDs set up in a RAID0 array which I use as mass storage. I access the drive very infrequently (once a day at most) and so I have set up Windows 7's power options to turn off idle disks after only 1 minute. This is fine, and the disks are turned off most of the time. However, I notice that Windows sometimes spins up the drives when I really, really don't want or need it to. This causes a 30 second delay as both drives spin up and lock up my system. Some examples of when this happens: 1) When I'm installing something using Windows Installer or Installshield; it seems to me as if they're using the drive with most available free space as the installer cache location... so my big RAID drive has to spin up! Most annoying. 2) Apparently, when I open a Java-based program which resides on my system drive and has nothing to do with my RAID drive! 3) At boot-up and shut-down time. At shutdown the drive spin up only for the computer to immediately shut down! Incredibly frustrating! I've already tried changing the letter of the drive, and at some points have removed the drive letter entirely, which solves the first two issues above. So my question (FINALLY!) is this: is there any way I can mark this drive as being for "storage only", so Windows basically does not see it at all until I actually invoke it somehow? Or is there any way I could set it up so that only specific programs have write access to it? For example, download managers, TeraCopy, etc. etc.? Basically I want it to be a "ghost drive" until I'm ready to use it and to stop Windows from spinning it up all the damn time! Thank you. :)

• File descriptor linked to socket or pipe in proc

  - by primero

  i have a question regarding the file descriptors and their linkage in the proc file system. I've observed that if i list the file descriptors of a certain process from proc ls -la /proc/1234/fd i get the following output: lr-x------ 1 root root 64 Sep 13 07:12 0 -> /dev/null l-wx------ 1 root root 64 Sep 13 07:12 1 -> /dev/null l-wx------ 1 root root 64 Sep 13 07:12 2 -> /dev/null lr-x------ 1 root root 64 Sep 13 07:12 3 -> pipe:[2744159739] l-wx------ 1 root root 64 Sep 13 07:12 4 -> pipe:[2744159739] lrwx------ 1 root root 64 Sep 13 07:12 5 -> socket:[2744160313] lrwx------ 1 root root 64 Sep 13 07:12 6 -> /var/lib/log/some.log I get the meaning of a file descriptor and i understand from my example the file descriptors 0 1 2 and 6, they are tied to physical resources on my computer, and also i guess 5 is connected to some resource on the network(because of the socket), but what i don't understand is the meaning of the numbers in the brackets. Do the point to some property of the resource? Also why are some of the links broken? And lastly as long as I asked a question already :) what is pipe?

• HAProxy appsession vs cookie precedence

  - by user1139473

  I am trying to find the best solution for balancing and keeping persistence on our application behind HAProxy. Here is our basic configuration: https://gist.github.com/endzyme/1804046b23c37beba520 After playing around with taking members down and up and also reloading the haproxy (with -sf) I have noticed that appsession isn't 100% effective, it would appear that sometimes it doesn't always 'request-learn'. I also tried to add a cookie JSESSION prefix to balance in case request-learn didn't take. Unfortunately it would present scenarios where the prefix would list svr2 but it was balanced to a different server. I am assuming it's because the appsession table takes first then sticks on that before using the cookie parameter. I have not tested with using cookie as an inserted option (not prefix on existing cookie) but I am thinking it would yield similar results. My question is: Which one is checked first, appsession or cookie, and is it an immediate catch after it reads the first one, or a fall through? Also as a follow up - is it not recommended to use both in the same backend? Cookie as I understand takes less memory resources, is agnostic to reloads and has way better reliability of persistence. Appsession I assume takes less cpu resource, since it's reading not writing. (Bonus Question: is there a way to inspect appsession/cookie table map? socket show table doesn't show anything except stick-tables) Many thanks in advance, -Nick

• Performance-optimizing Oracle 10g on a server that is also a Tomcat JSP app server?

  - by PKHunter

  I have inherited a simple RedHat 5 - 64bit platform. It has SCSI disks on RAID1, with 16GB of RAM. Double Core CPU. Oracle 10g, Release 2. This would be a decent platform for running the DB only, perhaps, but the same server in an "A-A mode" clustering (very simple) also runs Tomcat and there are several Java servlets running on this. Sadly there is no caching platform etc. We only use an external CDN for some html caching. I am personally more familiar with web environments on the LAMPP platform (apache, php, mysql, postgresql). PROBLEM: Because the server has both Tomcat JSP/Java and Oracle 10g running on the same server, with no caching, I have some issues of the server going down. Often, sadly. QUESTION: What are my options in terms of improving performance of all these different apps? Connection Pooling? Example, in Postgresql world we have PgBouncer, which really helps things. Does Oracle have something similar? Or is there a famous Java-based external pooler that people use in production environments? (I'm not familiar with Java) Any "SQL cache" as in the MySQL and Postgresql world? Any other kind of application cache, as "APC" or "eAccelarator" in the PHP world? The "OSCache" stuff from the Java world (JSP thingie I found on Google: http://onjava.com/pub/a/onjava/2005/01/05/jspcache.html?page=2) ... What else? Sorry if this is a noob question. I have googled and googled, but problem is I don't know what to google for, other than the broad general concepts above. So if not full answers, I would even appreciate basic pointers and I am happy to JFGI myself. Thanks!

• Local Network - Windows 7 and Vista can't see each other

  - by ca8msm

  I've got a strange issue at home that has been bugging me for weeks, but I really need to get it sorted now so I'll detail as much as I can and hopefully someone can spot what might might be wrong. I have a wireless router connected to the internet and 3 devices connected to it. They are: Name OS Network IPv4 PC1 Windows 7 WORKGROUP 192.168.2.2 LAPTOP1 Vista WORKGROUP 192.168.2.3 PS3 192.168.2.4 and they all get their IP addresses dynamically. Both PC1 and LAPTOP1 can ping PS3 and get a response. PC1 and LAPTOP1 are unable to ping each other by ip address unless I ping by their name (which bizarrely shows that it is pinging via the IPv6 address). Also, to confirm this both PC1 and LAPTOP1 can ping each other via the long IPv6 address that they both have so they can obviously see each other just not via IPv4. I've disabled the firewalls on both machines as well to rule that out. I don't really know what IPv6 is used for and I've tried disabling it on both machines but all that happens then is that neither machine can see each other at all then. Does anyone have any idea of what may be stopping them seeing each other, any ways I can look at fixing this, or any network tools that may help identify where it is failing? Thanks, Mark

• Why does the wireless network icon have a red X over it when everything seems to work?

  - by Kristo

  I booted my almost brand new laptop running Windows 7 this morning and noticed a red X through the wireless networking icon in the system tray. At first I thought something was wrong, but clicking on it shows a good connection to my wireless network. I had no problem getting here to post this question. I'm very new to Windows 7 so I have no idea how to troubleshoot this myself. Is there an actual problem here? Can I fix the icon so it doesn't falsely display an error (I assume that's what the red X means)? Here's what I know: I can get here to post this question. There's at least one unsecured network available that I'm not connected to. I can see a bunch of wireless networks, presumably from my neighbors' houses. There are no other computers turned on in my house right now. The device manager shows no problems with any devices. I can ping my default gateway, DNS, and yahoo.com with no problem.

• Should I update the kernel on a Linux machine?

  - by Legate

  As I understand it, updating to a new kernel (with the normal linux-image... package, not by rolling my own) requires a server restart. However, one of our servers (Ubuntu 10.04) is running several extensive screen sessions. Restarting kills those which is always a major hassle to their owners (mostly because of lost session histories). What should I do? I see several possibilites: Not doing anything, that is update only non-kernel packages (perhaps use apt-pinning?) Update the kernel, but not restart. (Is that smart? I seem to remember there might be some problems with loading kernel modules.) Updating the kernel and restarting. Is there perhaps some way to preserve the screen sessions? I guess it ultimately boils down to this question: How important is it to update the kernel? I posted this question here instead of askubuntu.com as I think this is not an Ubuntu-specific issue though this server is running Ubuntu.

• Did Adobe Photoshop just killed my Graphics Card for good?

  - by user6004

  I was working with Adobe Photoshop, just some regular work, when I came to edit a PSD file and change the text of some layer, when all of a sudden the PC froze. No mouse, screen is frozen, keyboard strokes aren't getting me anything, no Task Manager, nada. So I rebooted my PC, and then something quite terrifying appeared before my eyes. It was not the Checkdisk utility that was launched, that made me terrified (by the way, that reboot damaged the partition table of an external HDD that was connected at the time to my PC, but that's another story). It was the screen itself. Please have a look. So after Checkdisk finished and Windows loaded, I noticed that the resolution was not right. Instead of 1440x900 which I had set, it was 1280x1024. When I went to change it back, I had no option to change back to my old resolution, and has only 3 other general resolution properties, as if my Video Card (GeForce 8800 GTS btw) was not recognized. And what do you know, in the Device Manager it appeared with an exclamation mark. Inside the hardware, it said this: Windows has stopped this device because it has reported problems. (Code 43) Uninstalling the drivers, downloading the newest drivers from NVIDIA and installing them did not work. It always comes back to this. So, do you have any advice before I go out and buy a new graphics card? I thought this was the only option left, but maybe the experts at Super User can help me out. By the way, the dotted screen appears after every reboot, and I see the dots when the ASUS Motherboard screen shows up at boot. Thanks in advance.

• How can I get write permission for the Web (Inetpub) directory on a new Win 7 machine?

  - by marcipollo

  I mirror my Web site on my laptop, and am trying to move the mirror site to a new laptop. I copied the files to the Inetpub directory, and can view them perfectly, but they are read-only (the check-mark is grey, not black), and I cannot change the permission. When I un-check the read-only attribute on the Inetpub directory, and click "apply" it displays a dialog box stating that I need administrative permission to change the attributes. (I am logged in as an administrator). When I click "continue," it pops up another dialog box saying access is denied to the attributes of the file: c:\inetpub\custerr\en-us\500-100.asp That dialog box has an "ignore" button, and if I click that, it appears to work through the directory tree setting the permissions. It leaves all of the files (leafs) set to "read-write," but the directories remain "read only." I am using 64-bit Windows 7. I stopped the IIS service while doing all of this. Might it have something to do with the fact that I copied the files from a different machine in the workgroup (my old laptop)?

• "merging" multiple internet connections

  I've seen this question asked several times here on SF, but I'm looking for some updated information; specifically concerning Server 2012. I'm in the process of buying a home so I'm trying to get some plans together on how I want to structure my network. Internet speeds aren't the greatest and connections can be unreliable where the house is so I was thinking of having two DSL lines installed. My question is, how could I leverage those two connections to create the best network I can, in terms of speed and reliability. My parents will be moving in with me - they consume a lot of bandwidth as it is, but then add my internet traffic to it, and I'm headed for a lot of frustration. I thought I remember reading somewhere that Server 2012 has some new functionality to utilize multiple connections on multiple NICs in a way that wasn't possible in earlier versions of Server. Not sure if Windows will work but, I'm an application developer and spend the majority of my time in Windows environments. However, I've only recently returned to the Windows world, so I'd like my main server at home to run Win Server 2012 so that I can become more familiar with it.

• Outbound ports to allow through firewall

  - by dunxd

  This question was asked before, but in a rather general way. I'm asking more specifically based on my current requirements. We have a number of remote offices made up of a bunch of PCs and an ASA 5505 which is used as firewall and VPN termination point. In the offices we share the internet connection with one or more other organisations over whom we have very little control, asides from the config on the ASAs. For a bunch of reasons I'd like to lock down these ASA 5505s to only allow outbound traffic to ports used by applications we know we need. I'm putting a standard config to roll out to all the ASAs, and if we need to open up ports for the other orgs we can do it on request. But I want to leave open the most commonly required ports so we can get up and running without waiting on other folks technical staff to get back. I plan to allow the following TCP ports to support commonly required resources: POP3 (110 and 995) HTTP (80 and 443) IMAP4 (143 and 993) SMTP (25 and and 465) The question really is, what other ports do I need to leave open to allow for "normal" working. I've seen UDP port 53 for DNS as one. Are there any others that would be worth opening up? Just to note - I'll also be setting up monitoring systems to keep an eye on the ports we do allow. Any of the above could be misused of course. We'll also back all this up with signed agreements. But I'm aiming for a technical solutions where I don't have to start out with the full requirements of everyone we share connections with. See also: outbound ports that are always open

• Working with an external button box

  - by Scott

  I tried this question on Stack Overflow, but I was pointed here, so here goes: For a new project for myself, I am looking for a way to be able to (for example) open a pop-up window on my laptop, by pressing a button on an external device (to be build by myself, or at least bought) connected with USB. Basically I would be looking at something like a Arduino or Raspberry (IF I am looking in the right direction) with buttons on it, and as soon as I hit a button on the external box with physical buttons, a command activates on my laptop and for example opens a popup window in which I can input tekst. Does anyone know: 1) if it is possible to do this at all. 2) What equipment is needed for the external box, what programming is needed. I preffer .net (dot net) but maybe it can only be done with software from the external box. If anyone can point me in the right direction, like make/model of the external box or websites I would be very happy. I have knowledge of Visual Studio/.net but I am willing to learn other languages if .net is not an option for this project. Thanks in advance Scott PS: If anyone knows of some better tags, or at least knows what I mean and needs me to edit the question, please do tell me... I am new on Stack Overflow/Superuser.
