• Software mirroring (RAID1) versus "Fake Raid" for new Windows 7 install

  - by kquinn

  I've just ordered two new hard drives for my main desktop and a copy of Windows 7 Professional 64-bit. I'd like to do a clean install of Win7 onto the new drives (leaving my old XP Pro boot partition around for a while in case something goes disastrously wrong, etc.). I want to have them set up in mirrored (RAID-1) mode. My understanding is that Win7 Pro can do software mirroring, but can I set this up directly at install time? If so, how? Note that I'd like the disk to be split into three partitions (OS/Apps&Data/Bulk data), all of which should be mirrored. Would it be better (more reliable or faster) to use my motherboard's hardware RAID support? My motherboard is an older nVidia nForce 680i SLI, which is not the most stable of motherboards, and I'm not sure how trustworthy its RAID1 configuration might be (or if Win7 could even detect and install onto a hardware-mirrored volume). Also, the performance characteristics of RAID1 are rather different than RAID0 or RAID5, and I'm wondering if Win7's software mirroring might actually be faster than hardware RAID1 (for example, I'm more of a Unix admin when I have to wear the sysadmin hat, and I've had great success deploying ZFS; most hardware RAID1 implementations have to read both disks and compare results to look for data errors, but ZFS can read from only one disk in the mirror and just use the built-in checksum, meaning it can have up to 2x the number of reads in-flight, as long as there's no data corruption). Edit: Okay, my question about whether Windows 7 can do software mirroring has been answered, and it can. I'm still unsure whether Windows software RAID or my motherboard's hardware "fake RAID" function is a better choice, though. Remember, I'm only interested in mirroring -- not the more complicated striping or parity operations that generally show the poor performance of crappy motherboard RAID solutions.

• I can't connect to my network, except in safe mode

  - by eidylon

  My laptop cannot connect to my network all of a sudden except in safe mode. When it boots, it will show the networks available in the tray popup, but if I click connect on any, it says "Unable to connect" and the troubleshooter is useless. Shortly thereafter all the networks disappear. I have tried removing IPv6 support as I have seen that cause problems. No joy. I've also tried removing the wireless network adapter in Device Manager and reinstalling it, also no joy. I've also tried attaching a USB wireless adapter, and it has the same problem. If I boot in safe mode, then it has no problems at all. Three other devices in the house connect fine, so I am pretty sure it is nothing to do with the router. Any ideas what to check next? I am running Win7 Ultimate on a 2GHz Quadcore with 8GB RAM with a Broadcom 802.11n wireless card. EDIT: RE wired connections: What is very weird is that if i plug in a wired connection, then not only does it connect via the wired connection, but the wireLESS also starts working perfectly. And a soon as I unplug the wire, then the wireLESS stops working again! So it seems the wireless is right now working only in safe-mode, or when a wired connection is also plugged in.

• MSE updating fails, no warning or error message.

  - by WebDevHobo

  I'm running Windows 7 Ultimate, 32-bit. For the last couple of days, MSE doesn't fails to update, remaining stuck at version 1.75.119 I presume that an error log is created somewhere, or an event log, but I don't know where to find those. It just says "connection failed". Tried it at home, at work and friends places, but never works. Restarted computer a lot of times now, checked for Microsoft Updates in general, but nothing shows up. EDIT: I've opened a bounty for this, because I really don't know what to do anymore. The oldest answer(the long post) here did not work. Besides this problem, I'm having trouble using MSI installers too. I've had to add the SYSTEM group to a lot of maps and give them full control, but shouldn't the SYSTEM already be there? Also, I had to remove the "read-only" attribute from the ProgramData and Users folders, add the SYSTEM group there too and give them full control. Only then will the MSI install work and even then, it says I doesn't have the rights to create a shortcut on the desktop. Don't know what I need to modify and where for that. I'm saying this because I don't know how MSE updates, but if they use MSI files to do that, that might explain things. The SYSTEM group remains added, but every time I take away the read only attribute, click OK and check the settings again, read-only is still active... That's all I know. Screenshot, all those updates were manual:

• foswiki: hide some topic info when editing in WYSWYG mode.

  - by Mica

  I have a FOSWiki installation with a bunch of Topic templates already defined. the problem is, when a user selects the topic, they are presented with a bunch of extra information that they should not edit, and should not even see really. Is there a way to hide this content in the WYSWYG editor? Example: The topic template looks like this: <!-- * Foswiki.GenPDFAddOn Settings * Set GENPDFADDON_TITLE = <font size="7"><center>Foo</center></font> * Set GENPDFADDON_HEADFOOTFONT = helvetica * Set GENPDFADDON_FORMAT = pdf14 * Set GENPDFADDON_PERMISSIONS = print,no-copy * Set GENPDFADDON_ORIENTATION = portrait * Set GENPDFADDON_PAGESIZE = letter * Set GENPDFADDON_TOCLEVELS = 0 * Set GENPDFADDON_HEADERSHIFT = 0 --> <!-- PDFSTART --> <!-- HEADER LEFT "Foo:Bar" --> <!-- HEADER RIGHT "%BASETOPIC%" --> <!-- HEADER CENTER " " --> <!-- FOOTER RIGHT "Doc Rev %REVINFO{"r$rev - $date " web="%WEB%" topic="%BASETOPIC%"}%" --> <!-- FOOTER LEFT "F-xxx Rev A" --> <!-- FOOTER CENTER "Page $PAGE(1)" --> Header 1 foo etc. etc. etc <!-- pdfstop --> And when the user selects the topic template, they get all that in the WYSWYG editor. I would like to hide all that so when the user selects the topic template, they get Header 1 foo etc etc etc Without any of the other mark-up.

• Nvidia Linux Driver Huge Resolution

  - by darxsys

  I'm trying to setup a working CUDA SDK on my Linux Mint. I'm new to Linux and everything connected with it. So, I tried following some steps on how to install CUDA. Firstly, I downloaded a Linux driver from here: http://developer.nvidia.com/cuda/cuda-downloads version 295.41. After that, I barely found a way to run it. I did it like this: 1. typed in sudo init 1 in terminal and switched to root 2. typed service mdm stop 3. ran the *.run file downloaded from the link above Then it started installing the driver. It gave some warning messages, but I ignored it. After installation, I typed init 5 and it came back to GUI screen, BUT everything is huge. I restarted, still huge. My screen resolution is 640x480 on a 17 inch laptop monitor. I tried running Nvidia X Server Settings, but it says: "You do not appear to be using Nvidia X Driver. Please edit your X configuration file." I tried that. Nothing happened. I cant change the resolution because that Nvidia Settings thing gives no options. Then I googled some things, installing some packages - nothing. The biggest problem is I don't understand whats really going on. My laptop is a Samsung with i7 and Nvidia Gt 650M with optimus. I cant even install bumblebee, but that is something I will try if I manage to get my resolution to default. Please, help!

• Excel not properly recalculating values

  - by gms8994

  I have an excel sheet with values in it (this sheet is generated by a custom perl script, but I don't think that's where the problem lies). In it, I have a formula: =sum(indirect(concatenate(address(6,column()),":",address(17,column())))) The purpose of this formula is to give me the SUM() of the cells in the current column, between rows 6 and 17. In Gnumeric Spreadsheet, as soon as I open the file, this works. But in Excel (both 2003 and 2007), opening the file gives #VALUE! errors in the fields with this formula, stating that the INDIRECT call with the values $B$6:$B$17 will result in an error. Here's the kink in the issue. If I edit the field (via F2), and make no changes, and hit enter, the values update. Also, it seems, if I save the file as .xlsx (Excel 2007 format), the values update upon opening. Unfortunately, I'm not sure that creating an xlsx is a possibility with the modules that I'm using, and many of our clients probably wouldn't be able to use it anyway. Any suggestions? Editing 200+ files every month for each client isn't going to be feasible, so if there's something I'm missing, please let me know.

• Accounting setup in freeradius with mikrotik and the "always" module

  - by Matt

  I have a freeradius setup that is being used to provide authentication for users on a wireless network. The access points are all Mikrotik hardware and the users are connected 24/7. We've been using Daloradius with mysql and freeradius 2. The boss wants to use the accounting information and while this is all set up and appears to be working, I've found that not all the accounting information is present. Since our users may be connected for more than 24 hours at a time we keep this in here, it will reset some attributes daily so that the accounting packets work correctly. So he started poking around at this link: http://wiki.mikrotik.com/wiki/RouterOs_MySql_Freeradius#Configuring_RouterOs_for_Radius_.26_PPP.2A_AAA And was looking specifically at the following section. Since our users may be connected for more than 24 hours at a time we keep this in here, it will reset some attributes daily so that the accounting packets work correctly always fail { rcode = fail } always reject { rcode = reject } always ok { rcode = ok simulcount = 0 mpp = no } However, that link references freeradius 1 and I can't find this in the radius.conf file for freeradius 2. What does it do and could it be a reason I'm missing data? EDIT: I have found one issue. We have a backup freeradius server that is also receiving the accounting packets. Although they are replicating, it's only a master/slave configuration. If the slave receives accounting packets it won't replicate them back to the master. Although I suspect this might solve it, the boss is not convinced due to the always module. Is there anything special I need to configure in the mikrotik AP's or freeradius 2 for clients connected 24/7.

• IIS7 - how to place application in a folder inside application web site

  - by Nir

  I have a static web site with a blog (an asp.net application), the blog is in a subdirectory of the web site so: example.com/, example.com/Something.htm, example.com/folder/somefile.htm, etc. - are all static files example.com/blog, example.com/blog/categories.aspx, example.com/blog/2011/11/09/post-name.aspx, etc. - all go to the blog app I'm upgrading the static part of the web site to a dynamic site (also an asp.net application) and the blog is incompatible with the new app (the app needs handlers and modules loaded in web.config that don't work with the blog) Also, I have to keep all the old URLs the same - so I can't move the blog to a subdomain or the new app to a folder and the blog generates links based on its folder so clever redirection tricks wouldn't work. Is there a way to place an asp.net application in a folder inside another application (either as a real or virtual folder) so that the root web.config settings don't apply to the application folder? Or some other trick I didn't think of? The system is running IIS7 on Windows Server 2008 64bit, I have full control over the server's configuration. I can't modify the blog's source code but I can edit its web.config and other configuration. I can modify the source of the new application but I can't make it compatible with the blog (most of its usefulness comes from a 3rd party library that is not compatible with the blog). The blog in an asp.net 3.5 webforms application The new root application is an asp.net 4.0 mvc application

• Windows server 2008, Dns. I'm confused

  - by Dejan.S

  Hi. I recently setup a window server 2008 server at work. Keep in mind I have never worked with it before:). Background story is I try to host a couple of sites on the server through iis7, I got domains (currently hosted at other hosters for the moment). I want to point the domain NS to my server on all of them. I have read how to setup a DNS on the server, so far so good. now my dns is companyname.com in the server manager I got DNS / companyname.com in there I got ns.comanyname.com, in there I got Host(A) with the server ip now this is where I get confused about how things work with DNS, NS & Host(A). I dont know how to assign(so to speak) the Host(A) to one of my webapps hosted on the iis7, because that is the pointer right?. To leave an example to work with lets say, Hosted.com is hosted on my iis7, on port 81. You don't understand how great full I would be if somebody could explain this confusion. EDIT: Do I need to create a DNS for every site hosted on my server? Or just make a A Host/Record? Thanks guys

• Use one NIC to create multiple interfaces for Linux KVM

  - by Phanto

  I am working on a thesis research project, and I am having some difficulty figuring out how to make one NIC spawn several "bridge" interfaces such that each KVM VM can be seen on the local network. I am very new to KVM, and am still exploring what it can do. Below is the scenario that I am attempting to make (on a CentOS/RHEL 6 system): Linux KVM Host has 1 NIC (eth0) connected to a switch. Create multiple "bridge" or equivalent interfaces that are spawned off of eth0 that would provide a unique IP for each VM. This is so that each VM can communicate with other hosts on the network, and that other hosts on the network can communicate with the VM. IMPORTANT: I would like iptables on the KVM host to be able to manipulate/control/restrict the traffic that would be sent on those "bridge" interfaces. I would like to create a minimum of three VM's, each using their own unique "bridge" interfaces. I have previously made a br0 interface off of eth0, but unfortunately, I am unable to add any more to it. It appears that you can only bridge 1 interface to the NIC. I would like to bridge many to one. Would a tap device be able to do this? If so, how would it be set up? Effectively, I am attempting to replicate what can easily be created with VirtualBox on Windows, where each VM is given a "bridged" interface, and can live on the network. I want to achieve this very same thing with Linux KVM. Thank You EDIT: To be more descriptive, I want to achieve something that looks like this: This can be found on this page: http://en.gentoo-wiki.com/wiki/KVM#Networking_2 HOST +---------------+ | | KVM GUEST1 | | +--------------+ | +------+ | | | LAN ---+--- eth0 | +--+---+---- nic0 | KVM GUEST2 | | tap0----+ | |192.168.1.13 | +--------------+ | | tap1----+ | +--------------+ | | | +------+ | | | | | br0 +--+----------------------+---- nic0 | |192.168.1.12 | |192.168.1.14 | +---------------+ +--------------+

• The bottlenecks of any computer, what to look for?

  - by WebDevHobo

  Whether it is a laptop or a desktop, any computer is made up of several pieces of hardware that communicate with each other. Sending data back and forth to ensure that the user gets the desired results. I have seen some theoretical stuff on computers & hardware, but I wonder how it all comes together. CPU RAM Graphics Card L1 CACHE L2 CACHE L3 CACHE FSB ... And all other things. Which is the biggest bottle neck? Why would a person not want/need a big value in one of those categories in certain situations? P.S.: when reading the specs of the i5 750 processor, I came across this description: In place of the FSB, one or more high speed, point-to-point buses called Quick Path Interconnect (QPI) are used, formerly known as Common Serial Interconnect Bus or CSI. QPI features higher bandwidth than the traditional FSB and is better suited to system scaling. What is this, and how does it compare to FSB? EDIT: I am not planning to buy a computer at all. The goal of this question is to understand the internal relation of various hardware pieces, their specific functions and how they work together. For instance, I have heard to a somewhat higher-than-usual amount of L2/L3 Cache can help speed up your computer. What's up with saying that? Also I forgot to mention Hard-disk RPM.

• Problems with word completion on Windows Mobile

  - by Rowland Shaw

  For "some reason" the word completion function on my windows mobile phone (HTC Diamond, rebadged as a T-Mobile MDA Compact IV (UK) running WM6.1 with HTC Touch Flo 3D) hasn't worked since one of my firends was taking a look at the phone (I remember him bitching about it being too obtrusive for him, as an iPhone fanboy). I've checked all the obvious settings ( Start Input Word Completion ) and everything looks set there; I tried a hard reset, to no avail and even tried upgrading the ROM t the latest from my network provider. I even tried walking into the store where I bought the phone, and the staff couldn't fix the issue. I still have my old handset, which also runs WM6.1 (a T-Mobile MDA Compact III (UK), albeit without Touch Flo 3D), and the word completion works on there, so I'm a little confused as to why I can't get it to work again on my new handset. Can anybody identify why this might not be working, or help me fix it? Edit: Even "Touch Input Settings" has both "Word Completion in T9 mode" and "Word Completion in ABC mode" checked. The full qwerty keyboard option is in T9 mode, and word completion works for this input method; It still does not work for my preferred, "Letter Recogniser" method.

• Is it possible to install all packages from an APT repository?

  - by Kristoffer Hagen

  Is it possible to install all packages from an APT repository? I know it is possible to do it manually, but then you would need to know all the package names, and I don't. Any suggestions? Thanks. Update: Well, you guys are going to kill me for this, but the reason for my madness is that I want to install all the packages from BackTrack into my Ubuntu installation. I really don't like the idea of having it in a VM and having a separate partition for it is even more out of the question. I know that the folks at BackTrack doesn't like it when people leech their repositories, but that's what you get for releasing open source software. Stupid? maybe.. A valid reason? probably not.. Do I still want it? Yes. Another edit: I have now given up on this as it seems impossible to get it to work even by manually installing packages.

• Firefox 29 - how do I delete history entries visited fewer than x times

  - by lousyuser

  Context: I've been using my Firefox profile for a couple of years now. My history file has become huge, naturally. I got Firefox Sync set up between my main desktop PC and my laptop. HW configs: PC: i5-3450, 8 GB DDR3 RAM, Crucial M4 128 GB SSD laptop: Pentium SU4100, 4 GB DDR3 RAM, WD 5400 rpm HDD Accessing history entries when typing into the Awesome Bar on my desktop takes quite a long time despite the decent config, the laptop is even slower. The experience is quite unresponsive. I figured if I cleared the history up a little bit, I might avoid creating a new profile to speed things up. The question itself: to illustrate: Is there a way to delete all history entries that have been visited fewer than x (let's say 5) times and at the same time the recent visit is fewer than y (let's say 120) days old? afaik the history file is some kind of SQL database, but I'm not really sure how the data is saved, if there's a "safe way" to edit it and what the query to do what I need would look like. Thanks in advance for any help. I kept browsing through previous SuperUser questions to see if I could find relevant information. "In my Firefox profile directory, there is a filed named places.sqlite. Opening it with sqlite reveals (amongst others) the tables moz_places and moz_historyvisits. It seems that moz_historyvisits uses the primary of moz_places to refer to the URLs." As I'm unfamiliar with databases, I don't really understand the way the two tables mentioned in the quote are related. screenshot of a part of the tables I've noticed the visit_count is in a standard format, making it easy to work with. The last_visit_date looks encrypted to my naked eye, but I can't see in which way. Hope that helps, I'm at my wits' end.

• LDAP authentication issue with Kerio Connect

  - by djk

  Hi, We have Kerio Connect (mail server) running on a Windows Server 2003 server on a domain. In the webmail client, users are able to change their domain password. This functionality used to work fine until a user tried to change their password a few days ago, when every password they'd try would result in the webmail client claiming their password was "invalid". I spoke to Kerio about this and they claim that this error is returned by the domain controller, which supports my initial investigations. The error that the DC is logging when an attempt is made to change the password is this: "80090308: LdapErr: DSID-0C090334, comment: AcceptSecurityContext error, data 52e, vece" The "data 52e" part indicates that this is an "invalid credentials" error. I don't see how this can be as I've tried (in the Kerio Connect configuration) various accounts that have privileges to modify accounts, including my own as I am a domain admin. I have ran 'dcdiag' (all tests) on the DC and it came back passing every single one of them. I've searched high and low for an answer to this and came up empty. Does anyone have any idea why this may have suddenly started happening? Thanks! Edit: I should mention that the passwords we are changing to do comply with the complexity policy.

• debian VM refusing all traffic apart from http

  - by james lewis

  I've got a VM with a fresh install of Debian (wheezy) and I've installed node and mongo on it. The VM is using a bridged network connection so I was expecting to be able to point my host machines browser at the ip address of the Debian VM (port 1337 for my node example or port 28017 for my mongo status page) and see one of the two services (node or mongo). My requests are refused though. As far as I can tell Debian allows all traffic by default and you have to manually configure iptables to drop traffic. I've checked iptables and it says it's setup to allow anything through. It looks like this: root@devbox:/home/jlewis# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination As a test I setup nginx and I was able to get to the nginx landing page from my host no problems so obviously http traffic is allowed. I then set nginx up to forward all traffic upstream to mongo - no problems there, I was able to see the status page. I then did the same for my example node server and again, no problems. So http traffic is fine, but all other traffic is blocked. Anyone know why debian might be refusing all other traffic other than iptables being setup to drop it?

• Extending home network using multiple access point originating from another access point

  - by cyberjar09

  I have a home network with the current setup (RJ45 running from main router to access point) : +-------------+ +--------------+ | 192.168.2.1 | |192.168.2.2 | | router +--------------->access point 1| +-----^-------+ +--------------+ | | +-----+--------+ | 192.168.1.1 | | modem | +-----^--------+ | | | | +--+--+ | ISP | +-----+ However I would like to extend the network to two more floors in the house via the existing Access Point (router is too far and not reachable using a network cable, hence I need to extend using current access point). Please see diagram below : +-------------+ +--------------+ +----------------+ | 192.168.2.1 | |192.168.2.2 | | 192.168.2.3 | | router +--------------->access point 1+----------> access point 2 | +-----^-------+ +--------+-----+ +----------------+ | | | | +-----+--------+ | | 192.168.1.1 | | | modem | | +-----^--------+ | +----------------+ | +----------------> 192.168.2.4 | | | access point 3 | | +----------------+ | +--+--+ | ISP | +-----+ Q1 : is this setup possible? Q2 : if possible, will I have to do anything different from what I did to setup access point 1? edit 1 : I am trying to study the dd-wrt documentation to see which would be the correct mode of operation for me Linking Routers but Im confused because I dont see any info on how to use an existing Access point to extend the signal of the SSID. If anyone could point me to the correct wiki for how I should setup AP2 and AP3 based on AP1, it would be very helpful. For AP1, I did the following Use static IP and setup same SSID as primary wireless router use same security as primary wireless router make AP1 point to 192.168.2.1 (primary router) for DHCP Thanks in advance.

• Limiting access in Silverlight\Pivotviewer

  - by sparaflAsh

  I'm going to deploy a pivotviewer application. As some of you might know this silverlight application load a .cxml index file for a group of images. My need is to make .cxml file and image files not accessible for the user. Now, if I don't have a need I usually code like this in C# and the file is hosted in the documentroot: _cxml = new CxmlCollectionSource(new Uri("http://www.myurl.it/Collection.cxml", UriKind.Absolute)); This means that my cxml and then the images are available by http for everyone who knows the URI. I'm a newbie to server configuration, so any help/hint would be deeply appreciated. Someone suggested me to take the files out of the root, but it seems like I can't go to pick them up if they are not a URL in Silverlight. At least I didn't managed to understand how. Someone else suggested me to play with web.config file to hide URLs, but I don't really know where to start. My question is, what's the best practice to hide my stuff? Obviously I can edit the question if you need more details.

• remove tasksel lamp-server

  - by RickyA

  I was tricked in running "sudo tasksel install lamp-server" on the wrong server (UBUNTU 10.4). Now I am stuck with a system where apache won't start because of a "Address already in use: make_sock: could not bind to address 0.0.0.0:80" error. I now want to remove this task, but documentation on that crappy tasksel says you cant use it to uninstall stuff (!!!???). My question is where can I see what packages it installed, and how can I get rid of a selection of them (apt-get?). I want to keep apache, but mysql, php and the other stuff can go... [edit] I managed to get rid of most of the lamp stack. (/var/logs/dpkg.log is usefull for recently installed packages). However it did something in a configuration somewhere, and now two apache intstances start at boottime. Killing the first one and starting a new one gets rid of the "could not bind at adress..." error. Does anyone know where the startup of the first one is configured?

• How to setup Mac server to use two gateways

  - by Brady

  I recently asked this question: How to set Mac server to use different Gateway for internet bound traffic The answer given works but has presented me with another issue that I didnt make clear in that question. Here is my network layout as it stands: At the moment outside staff members use some services on the existing internet 1 link. Those services are hosted by the Mac server. If I change the gateway of the Mac server to the second modem those outside staff lose visabilty on those services. Now I dont know how to go about solving this issue. I want the second link to be used when the Mac server goes to rsync data offsite but everything else use link one. How do I do this? Thanks Scott EDIT: This has been resolved by setting the default gateway on the Mac server to 192.168.1.254 Thus leaving everything on the network as it was before. but to get the Mac server to use the other link for rsync I've added a route to the Mac server to route traffic to the rsync server through the second gateway. sudo route add -net {server IP's}/{Netmask} 192.168.1.1 I've awarded the answer to gravyface for pointing me to a post on how to make this route persistant in Mac

I read today somewhere that if you create unix account postfix will recognize it as email address so if your account username was ant your email would be [email protected]. So I tested that and tried to send email to [email protected] and I successfully received mail. When I try to send the email with ant task script, I'm not able to connect : Failed messages: javax.mail.MessagingException: Could not connect to SMTP host: mail.example.com, port: 25; nested exception is: java.net.ConnectException: Connection timed out: connect What am I missing here?

• AMD 700, 800 series chipset. I'm lost.

  - by Shiki

  I've been an Intel / NVidia user ever since I started using computers. Intel really gone up with the prices, and they won't get cheaper. So I decided to get an AMD. But WHICH one? I mean.. not shopping question but.. what are the differences? Like: 880GMA comes only with a single PCI ex and it looks like a chinese replica (no offense). While 890FX comes with 5PCI-ex for QuadCrossfire. Also.. what's the deal with 7xx series? I mean.. its the same price. Yet its older? Or why is it 7xx? Isn't there a single chipset between? Not chinese YET it's durable/fine for long-term usage? What it should know (desktop stuff): NVidia GPU (Zalman AMP2 GTX 260^2 (one card)) Phenom 1090T cpu A somewhat good audio. Any ideas which is the chipset I'm searching for? If this sounds too much of a shopping question, feel free to edit. I just want some clarification on these chipsets.

• Postfix / Dovecot email setup not storing email

  - by Nick Duffell

  I'm trying to setup postfix / dovecot on my debian server to use it for a mail server. I set everything up according to a tutorial on the net, and it all seemed OK. I can send emails from it, so SMTP is not a problem, however I cannot receive emails. Looking into the files in /home/nick/mail/ I can see that if I send an email to myself (from the server, to itself) the emails are there, but are put straight into the Deleted Messages folder. I don't know why this is. When I send an email from another mail account (not on this server), the emails are nowhere to be found. Also, looking at the log file /var/log/mail.log all seems to be OK, I get the following when I receive an email, which looks OK to me: Nov 7 22:47:22 nickduffell postfix/local[17825]: 05B1173581A6: to=, relay=local, delay=0.37, delays=0.31/0.02/0/0.03, dsn=2.0.0, status=sent (delivered to mailbox) Any ideas? Thanks EDIT: I should also add that although the emails I send myself are in the Deleted Messages folder, and in my mail client I can see that "Trash" has 3 items, I cannot download them in my mail client...
