• VS2010 and CSS: What is the best way to position a single form control

  - by George

  OK, I have a ton of controls on my page that I need to individually place. I need to set a margin here, a padding there, etc. None of these particular styles that I want to apply will be applied to more than control. What is the bets practice for determining at which level the style is placed, etc? OK, my choices are 1) External CSS file 1A) Using ClientIdMode = Auto (the default) I could assign a unique CssClass value to the ASP.NET control and, in the external CSS file, create a class selector that would only be applied to that one control. 1B) User Client ID = Predicatable In the external CSS file, I could determine what the ID will be for the controls of interest and create an ID selector (#ControlID{Style} ). However, I fear maintenance issues due to including/removing parent containers that would cause the ID to change. 1C) User Client ID = Static. I could choose static IDs for the controls such that I minimize the likelihood of a clash with auto generated IDs (perhaps by prefixing the ID with "StaticID_" and use an external stylesheet with ID selectors. 2) I could place the style right on the control. The only disadvantage here, as I see it, is that style info is brought down each time instead of being cached , which is what I'd get using an external CSS. If a style isn't resused, I personally don't see much benefit to placing it in an external file, though please explain why if you disagree. Is there moire of a reason that "It's nice to have all the CSS in one place?"

• What are the linkage of the following functions?

  - by Derui Si

  When I was reading the c++ 03 standard (7.1.1 Storage class specifiers [dcl.stc]), there are some examples as below, I'm not able to tell how the linkage of each successive declarations is determined? Could anyone help here? Thanks in advance! static char* f(); // f() has internal linkage char* f() { /* ... */ } // f() still has internal linkage char* g(); // g() has external linkage static char* g() { /* ... */ } // error: inconsistent linkage void h(); inline void h(); // external linkage inline void l(); void l(); // external linkage inline void m(); extern void m(); // external linkage static void n(); inline void n(); // internal linkage static int a; // a has internal linkage int a; // error: two definitions static int b; // b has internal linkage extern int b; // b still has internal linkage int c; // c has external linkage static int c; // error: inconsistent linkage extern int d; // d has external linkage static int d; // error: inconsistent linkage UPD: Additionally, how can I understand the statement in the standard, " The linkages implied by successive declarations for a given entity shall agree. That is, within a given scope, each declaration declaring the same object name or the same overloading of a function name shall imply the same linkage. Each function in a given set of overloaded functions can have a different linkage, however."

• A brief introduction to BRM and architecture

  - by Yani Miguel

  Oracle Communications Billing and Revenue Management (Oracle BRM) is the telcos industry´s leading solution intended for communications service providers. This post encourages to know BRM starting with the basics. History Portal was a billing and revenue managament solution to communications industry created by Portal Software. In 2006 Oracle acquired Portal Software and the solution was renamed BRM. Today Oracle BRM is the first end-to-end packaged enterprise software suite for the communications industry, however BRM is just one more product in the catalog of OSS solutions that Oracle offers. BRM can bill and manage all communications services including wireline, wireless, broadband, cable, voice over IP, IPTV, music, and video. BRM Architecture BRM´s architecture consists of 4 layers or tiers. Through these layers are the data, bussines logic and interfaces to connect graphical client tools.Application tier This layer provides GUI client tools enabling communication to other layers through open APIs. Some BRM client applications are: Customer Center Pricing Center Universal Event Loader Web Server BRM Billing Application Collections Center Permissioning Center Furthermore, this layer is where are provided real-time external events. Bussines Process Tier Although all layers are equally important, I think it deserves more atention because in this tier BRM functionality is implemented. All functions that give life to BRM are in this layer coded in C language called Opcodes (System Processes in the image). Any changes or additional functionality should be made here, so when we try to customize the product, we will most of the time programming in this layer (Business Policies in the image).Bussines Process Tier Features: Implements Portal system functionalityValidates data from the application tierModifies Portal behavior through business policies. Business policies can by customized.Triggers external systems using event notification. Object Tier This layer is responsible for transfer the BRM requests into database language and translate BRM requests into external system requests. Without it, the business logic (data from Bussines Process Tier) could not be understood by the relational database. Data tier Data tier is responsable for the storage of BRM database and other external systems databases. External systems include credit card, tax, and directory servers. Finally, It's important to note that BRM is designed to easily integrate with the following solutions:AIA 2.4 Siebel CRM E-Business Suite - G/L onlyCommunications Services Gatekeeper Oracle BI Publisher. Personally, I think that BRM could improve migrating client-server architecture to a fully web platform that works with Oracle Middleware like any product of the Fusion Middleware family. Hopefully there are already initiatives in this area.

• ecommerce item deleted by user, 301 rediret to HOME PAGE or 404 not found?

  - by Marco Demaio

  I know this question is someway similar to this one where they reccomend using 404, but after reading this other one where they suggest to use 301 when changing site urls (in the specific case was due to redesign/refactoring) I get a bit of confused and I hope someone could clarify for this specific example: Let's say I have an ecommerce site, let's also say the final user inserted some interesting items in the site and the ecommerce webapp created the item pages at the urls: http://...?id=20, http://...?id=30 etc. Now let's say some of these interesting items got many external links toward them from many other sites because some people found those items very interesting and linked to them. After some years the final user deletes those items, so obviously the pages/urls http://...?id=20, http://...?id=30, etc. now do not exist anymore, but still many pages on the web are linking toward them. What should the ecommerce site do now, just show a 404 page for those items? But, I'm confused, wouldn't this loose all the Google PR passed by the external links to the items pages? So isn't it better to use 301 redirect to HOME PAGE that at least passes the PR to the HOME PAGE? Thanks, EDIT: Well, according to answeres the best thing to do so far is to do a 404/410. In order to make this question more complete, I would like to talk about a special case, just to make sure I understood. properly. Let's say the user creates those items again (the ones he previously deleted at point 4), maybe he changes a bit their names and description, but they are basically the same items. The webapp has no way to know these new added items were the old items so it obviously create them as new items with new urls http://...?id=100, http://...?id=101, does it makes sense at this point to redirect 301 the old urls to the new ones? MORE EDIT (It would be VERY IMPORTANT TO UNDERSTAND): Well according to the clever answers received so far it seems for the special case, explained in my last EDIT, I could use 301, since it's something of not deceptive cause basically the new pages is a replacement for the old page in term of contents. This is basically done to keep the PR passed from external link and also for better user experience. But beside the user experince, that is discussible (*1), in order to preserve PR from external broken linlks why not just always use 301, In my understanding Google dislikes duplicated contents, but are we sure that 301 redirect to HOME PAGE is seen as duplicated contents for Google?! Google itself suggests to redircet 301 index.html to document root so if they consider 301 as duplicated contents wouldn't that be considered duplicated contents too?! Why do they suggest it? Let me provoke you: “why not just add a 301 to HOME PAGE for every not found page?” (*1) as a user, when I follo a broken url from some external link to some website's page I would stick more on this website if I get redirected to HOME PAGE rather than seeing a 404 page where I would think the webiste does not even exist anymore and maybe I don't even try to go to HOME PAGE of the website.

• Why are my hard drives failing?

  - by WishCow

  I have a small Ubuntu server running at home, with 2 HDDs. There are two software raids (raid1) on the disks, managed by mdadm, which I believe is irrelevant, but mentioning it anyway. Both of the HDDs are Western Digital, and have been used for around 2 years, when one of them started making clicking noises, and died. I figured that maybe it's natural after 2 years, so I bought a new one, and resynced the raid arrays. After about a month, the other drive also died. I didn't get suspicious, since both drives have been bought at the same time, it's not that surprising to see both of them near each other, so I bought another one. So far, 2 old drives failed, and 2 brand new in the system. After one month, one of the new drives died. This is when it started getting suspicious. Since the PC was put together from some really old parts (think AthlonXP), I figured that maybe the motherboard's SATA controller is the culprit. Of course you can't switch parts easily in an old PC like this, so I bought a whole system, new MB, new CPU, new RAM. Took the just failed drive back, since it was under warranty, and got it replaced. So it is up to 2 failed drives from the old ones, and 1 failed drive from the new ones. No problems, for 1 month. After that errors were creeping up again in /var/log/messages, and mdadm was reporting raid array failures. I started tearing my hair out. Everything is new in the system, it's up to the third brand new HDD, it's simply not possible that all of the new drives that I bought were faulty. Let's see what is still common... the cables. Okay, long shot, let's replace the SATA cables. Take HDD back, smile to the guy at the counter and say that I'm really unlucky. He replaces the HDD. I come home, one month passes and one of HDDs fails, again. I'm not joking. Two of the brand new HDDs have failed. Maybe it's a bug in the OS. Let's see what the manufacturer's testing tool says. Download testing tool, burn it to a CD, reboot, leave HDD testing overnight. Test says that the drive is faulty, and I should back up everything, if I still can. I don't know what's happening, but it does not look like a software problem, something is definitely thrashing the HDDs. I should mention now, that the whole system is in a shoebox. Since there are a load of "build your own ikea case" stuff, I thought there shouldn't be any problems throwing the thing in a box, and stuffing it away somewhere. The box is well ventilated, but I thought that just maybe the drives were overheating. There is no other possible answer to this. So I took the HDD back, and got it replaced (for the 3rd time), and bought HDD coolers. And just now, I have heard the sound of doom. click click whizzzzzzzzz. SSH into the box: You have new mail! mail r 1 DegradedArrayEvent on /dev/md0 ... dmesg output: [47128.000051] ata3: lost interrupt (Status 0x50) [47128.000097] end_request: I/O error, dev sda, sector 58588863 [47128.000134] md: super_written gets error=-5, uptodate=0 [48043.976054] ata3: lost interrupt (Status 0x50) [48043.976086] ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen [48043.976132] ata3.00: cmd c8/00:18:bf:40:52/00:00:00:00:00/e1 tag 0 dma 12288 in [48043.976135] res 40/00:00:00:4f:c2/00:00:00:00:00/00 Emask 0x4 (timeout) [48043.976208] ata3.00: status: { DRDY } [48043.976241] ata3: soft resetting link [48044.148446] ata3.00: configured for UDMA/133 [48044.148457] ata3.00: device reported invalid CHS sector 0 [48044.148477] ata3: EH complete Recap: No possibility of overheating 6 drives have failed, 4 of those have been brand new. I'm not sure now that the original two have been faulty, or suffered the same thing that the new ones. There is nothing common in the system, apart from the OS which is Ubuntu Karmic now (started with Jaunty). New MB, new CPU, new RAM, new SATA cables. No, the little holes on the HDD are not covered I'm crying. Really. I don't have the face to return to the store now, it's not possible for 4 drives to fail under 4 months. A few ideas that I have been thinking: Is it possible that I fuck up something when I partition and resync the drives? Can it be so bad that it physicaly wrecks the drive? (since the vendor supplied tool says that the drive is damaged) I do the partitoning with fdisk, and use the same block size for the raid1 partitions (I check the exact block sizes with fdisk -lu) Is it possible that the linux kernel or mdadm, or something is not compatible with this exact brand of HDDs, and thrashes them? Is it possible that it may be the shoebox? Try placing it somewhere else? It's under a shelf now, so humidity is not a problem either. Is it possible that a normal PC case will solve my problem (I'm going to shoot myself then)? I will get a picture tomorrow. Am I just simply cursed? Any help or speculation is greatly appreciated. Edit: The power strip is guarded against overvoltage. Edit2: I have moved inbetween these 4 months, so the possibility of the cause being "dirty" electricity in both places, is very low. Edit3: I have checked the voltages in the BIOS (couldn't borrow a multimeter), and they are all seem correct, the biggest discrepancy is in the 12V, because it's supplying 11.3. Should I be worried about that? Edit4: I put my desktop PC's PSU into the server. The BIOS reported much more accurate voltage readings, and also it has successfully rebuilt the raid1 array, which took some 3-4 hours, so I feel a little positive now. Will get a new PSU tomorrow to test with that. Also, attaching the picture about the box: (disregard the 3rd drive)

• Establishing a tcp connection from within a DLL

  - by Nicholas Hollander

  I'm trying to write a piece of code that will allow me to establish a TCP connection from within a DLL file. Here's my situation: I have a ruby application that needs to be able to send and receive data over a socket, but I can not access the native ruby socket methods because of the environment in which it will be running. I can however access a DLL file and run the functions within that, so I figured I would create a wrapper for winsock. Unfortunately, attempting to take a piece of code that should connect to a TCP socket in a normal C++ application throws a slew of LNK2019 errors that I can not for the life of me resolve. This is the method I'm using to connect: //Socket variable SOCKET s; //Establishes a connection to the server int server_connect(char* addr, int port) { //Start up Winsock WSADATA wsadata; int error = WSAStartup(0x0202, &wsadata); //Check if something happened if (error) return -1; //Verify Winock version if (wsadata.wVersion != 0x0202) { //Clean up and close WSACleanup(); return -2; } //Get the information needed to finalize a socket SOCKADDR_IN target; target.sin_family = AF_INET; //Address family internet target.sin_port = _WINSOCKAPI_::htons(port); //Port # target.sin_addr.s_addr = inet_addr(addr); //Create the socket s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); if (s == INVALID_SOCKET) { return -3; } //Try connecting if (connect(s, (SOCKADDR *)&target, sizeof(target)) == SOCKET_ERROR) { //Failed to connect return -4; } else { //Success return 1; } } The exact errors that I'm receiving are: Error 1 error LNK2019: unresolved external symbol _closesocket@4 referenced in function _server_disconnect [Project Path] Error 2 error LNK2019: unresolved external symbol _connect@12 referenced in function _server_connect [Project Path] Error 3 error LNK2019: unresolved external symbol _htons@4 referenced in function _server_connect [Project Path] Error 4 error LNK2019: unresolved external symbol _inet_addr@4 referenced in function _server_connect [Project Path] Error 5 error LNK2019: unresolved external symbol _socket@12 referenced in function _server_connect [Project Path] Error 6 error LNK2019: unresolved external symbol _WSAStartup@8 referenced in function _server_connect [Project Path] Error 7 error LNK2019: unresolved external symbol _WSACleanup@0 referenced in function _server_connect [Project Path] Error 8 error LNK1120: 7 unresolved externals [Project Path] 1 1 Many thanks!

• Xenserver boot error

  - by Adrian

  I'm trying to get Xenserver 5.5 running on a spare computer here, hardware specs: Intel Q6600, 4GB Ram, and Gigabyte GA-P35-DS3R motherboard Xenserver itself installs fine onto a 150GB sata hdd, however it fails to boot whatsoever, giving this garbled mess: http://img697.imageshack.us/img697/9918/biosi.jpg it's not frozen because if I press enter it just prints a different garble and it also says "could not find kernel image". The strangest thing is if I put that hdd in my desktop and assign it to a VMWare desktop vm (under the ESX profile no less) it boots perfectly... leading me to believe there are no problems with the install or the hdd itself. From what I can tell the error seems to be occuring completely seperately to Xenserver, in the bootloader extlinux?. If there was a motherboard compatibility issue I would think it would also have manifested during installation, and the fact the problem seems to be with the booting into Xen makes me doubt this. Any ideas guys? (I'm using Xen because it can do PCI passthrough without VT-d.)

• Path of md device wrong after reboot

  - by flammi88

  I have to set up a software raid (level1) on a Ubuntu server 12.04. It should serve files in the network via Samba. The server has the following disks: 250gb Sata hdd (Ubuntu is installed on that drive) 2 TB Sata hdd (first disk in raid array, data disk) 2 TB Sata hdd (second data disk) I created one partition on every data disk with the type Linux raid autodetect. In the second step I created the raid1 with the following command: mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdb1 /dev/sdc1 After that, I added the array to the mdconf: mdadm --examine --scan >> /etc/mdadm/mdadm.conf The problem is: After a reboot the array is not available on the path /dev/md0. Instead of that it gets reassembled as /dev/md/0 but it is not very reliable. Has anybody a solution for this issue?

• Switching BIOS SATA RAID/AHCI setting causes BSOD at Windows Start - Why?

  - by thephatp

  I just changed my disk setup from: 1 SATA HDD Primary OS Disk 2x SATA HDD Backup Disks in RAID 1 TO: 1 SATA SSD Primary OS Disk 1 SATA HDD Backup Disk [No RAID] Everything worked great, no problem. So, since I don't have a RAID array anymore, I decided that I could change my BIOS setting to AHCI instead of RAID. I have a Gigabyte GA-P35-DS3R v1.0 mobo. These are my steps: Settings Integrated Peripherals "SATA RAID/AHCI Mode" = RAID -- Changed this setting to AHCI Reboot Windows Start screen shows up, but as the color orbs are spinning into focus, BSOD and immediate restart Repeated reboot several times, same outcome Next Step: Launch BIOS settings Integrated Peripherals "Onboard SATA/IDE Ctrl Mode" = RAID -- Changed this setting to AHCI Reboot Windows Start screen shows up, but as the color orbs are spinning into focus, BSOD and immediate restart Repeated reboot several times, same outcome Switch both settings back to RAID, reboot, and Windows starts up just fine, no issues. What am I missing? Why can't I set it to AHCI mode without BSODs?

• Time Machine doesn't back up some folders/files (that it should)

  - by Eric

  MacBook Pro 17" (Snow Leopard) -- WD 2TB external drive MacBook Pro 13" (Snow Leopard) -- Seagate 1TB external drive I find that Time Machine sometimes doesn't back up new folders (and the files in them). This occurs both when I choose "Back Up Now" from the Time Machine icon in the Menu Bar and in TM's scheduled backups. These are not excluded folders (nor are then in the TM do-not-back-up list); they're perfectly normal folders (at various locations) inside my home folder. The only way to force them to be backed up is to restart the computer (unmounting & mounting the TM external disk does not help). There seems to be a correlation with new folders (i.e., it's more likely to happen that an entire new folder is not backed up), but this may just be observer bias (because those are the folders that I go check to see if they've been backed up). It's not computer dependent (it happens on two different computers). It's not external disk dependent (it happens on two different external disks). It's not time dependent (not restarting for several days does not fix the problem). What does a restart change that these other events don't? I'm considering deleting the /.fseventsd folder (without restarting the computer) to see if that helps. I haven't tried logging out and logging in (without restarting the computer).

• Windows Vista: Screen remains darkened for 30-60 seconds *after* UAC prompt

  - by sf2k

  Fixing someone's Vista computer. Process: I click any program or process that opens a User Account Control prompt. Screen goes dim so you may hit Continue to perform a secure user action. I click Continue Screen goes black for 30 seconds to 1 minute while you wait for the screen to return. In another example I click Cancel and screen still then goes black for 30 seconds to a minute. In that timeframe a chime goes off while you wait. (No chime if it was being cancelled.) Then screen comes back to continue with whatever. Something is occurring after the UAC prompt. Considering everything is practically a UAC acceptance this can get pretty annoying pretty quickly. Laptop has external monitor to regular external plug. Works fine. Laptop also has USB IOGEAR additional external video card. This is problematic but when unplugged same above behaviour occurs. I've ruled out monitor interference since same blackout after the UAC prompt appears with external monitors plugged in or when rebooted with no external monitors. Any suggestions on how to address this problem?

• Change Gnome-Panel profile at startup according to number of displays

  - by ifischer

  I'm running Ubuntu 10.04 on a Laptop. I have a startup script which enables external displays, if they are connected. It runs at GDM startup, configured in /etc/gdm/Init/Default. When i'm running without external displays, Gnome should use 2 Panels. When i'm using 2 external displays, Gnome should add an additional Panel to the second display. But this should of course be removed again if i detach the external displays (and restart). Can i configure this use case by using Gnome Panel-profiles? I read that there is a startup option "--profile" for gnome-panel, but i don't know how and where i could switch the profile, especially because this has to be done after recognizing the number of displays. Or can i add a general Gnome profile and switch between those profiles somehow to achieve this behavior?

• Ubuntu not showing disk

  - by ojek

  I have a laptop which had broken windows 7 installed on it. I created a ubuntu live usb and tried installing ubuntu over that win7. After a few minutes, I got an error message, so I needed to restart the computer. Now the laptop says that there is no bootable device - reasonable message given that there was an error during linux installation. But: Bios can see my hard drive, When I start ubuntu in live mode, and try either sudo fdisk -l or gparted, it doesn't show any hard disk drives. I am 90% sure that hdd is broken, but it is wierd that bios can see it, and ubuntu doesn't. How can I be 100% sure about that hdd? Is there any additional way of detecting my hdd from ubuntu?

• Cross domain LDAP

  - by Adam

  For a system we are developing we have 2 domains an internal and an external domain with bi directional trust between them. However the servers are only able to connect to their own DC's. We have an application server on the internal domain which needs to use an LDAP query to gather a list of users from a group on the external domain. How do i go about writing an LDAP query that asks one DC to go ask another DC for a list of users. I tried querying the internal DC with the same LDAP query I would use if it could hit the external DC directly but this does not work. When i use Softerra LDAP Administraor I can view the full hierarchy of the interal domain but despite the trust relationship between domains i am unable to see any of the external doamin. Any suggestions or help would be greatly appreciated

• How to prevent hard drive from spinning down Windows 7?

  - by JL.

  I had a Western Digital External 1TB drive, which I was accessing via USB. I decided one day, that I would prefer to mount the HDD in my case, and access it via SATA interface. So I took it apart, and the actual mounting was a breeze. The only thing is, I think the device has some default power saving features, which means the device tends to stop spinning when idle for (x) amount of time. This creates delays when I am accessing the HDD. Is there anyway I can turn off these power saving features for this HDD?

• How to change from own Internal/Extrernal DNS to use an outsourced service like DNS Made Easy?

  - by Joakim

  Our current setup is a co-located linux box with an openvz kernel with a handful virtual containers for www, mail etc. and one container run Bind9 with a split views configuration serving External and Internal DNS. The HW-Node runs a shorewall firewall and all containers uses private ip's. The box (and DNS) basically handles web and mail for a handful domains and it works well but we still think it would be a good idea to outsource the public DNS and now to my question... Although I am fairly comfortable with the server stuff and DNS, I'm far from a pro and guess I basically need some confirmation that I am thinking in the right direction in that I basically just move the content of our external view (with zone files) to the external service and keep the internal view (or actually remove the view), update the new external DNS with thier names servers, update the info at my registrar and wait for propagation or have I missed something? Maybe someone else here run something similar already and can share some exteriences? I found this question which at least confirms it can be done.

• partitioning problems

  - by Remus Rigo

  I had on my laptop a dual system (Ubuntu 11.04 and Windows 7) and someway the partitions messed-up. Windows stopped from booting, I just got a blinking cursor, but Ubuntu worked fine. I tried to fix the windows boot (fixmbr, fixboot, bootsect /nt60 C:/....) but now grub was overwritten and I have no OS. Finally I formatted the hdd (low format), installed Windows, partition hdd with paragon partition manager and now I want to install Ubuntu, but Ubuntu sees an empty hdd, weird, can anyone tell me what can I do? EDIT: I have created: partition 1: 100MB ntfs - windows reserved (drive B) partition 2: 50GB ntfs win 7 (drive C) partition 3: 50GB ext3 linux partition 4: 'the rest' ntfs for data (drive E) (the swap i will create after)

• cannot move file: "file cannot be found" (Windows XP)

  - by Steve

  I have some CR2 files in a subfolder of My Documents called My Photos on a Windows XP PC. I want to move them across a WIFI network to an external HDD attached to a Windows 7 PC. I have read/write permissions on the external HDD, as I mapped to this HDD using the Windows 7 user account. When I try to move a single CR2 file, I receive "Cannot copy IMG_3317: Cannot find the specified file. Make sure you specify the correct path and file name." If I refresh the source folder, the file is still there. It is not read only, and I have read/write access to the source file. I can view its properties. Why can't I move this file? I have been able to move similar files in the past.

• ssh port forwarding / security risk

  - by jcooper

  Hi there, I want to access a web application running on a web server behind my office firewall from an external machine. We have a bastion host running sshd that is accessible from the Internet. I want to know if this solution is a bad idea: Create an account on the bastion host with shell=/bin/false and no password ('testuser') Create a ssh RSA key on the external machine Add the public RSA key to the testuser's authorized_keys file ssh to the bastion host from the external host using: ssh -N 8888:targethost:80 run my tests from the external host shut down the ssh tunnel I understand that if my RSA private key were compromised then someone could ssh to the bastion host. But are there other reasons this solution is a bad idea? thank you!

• Proper Network Infastructure Setup DMZ, VPN, Routing Hardware Question

  - by NickToyota

  Greetings Server Fault Universe, So here's a quick background. Two weeks ago I started a new position as the systems administrator for an expanding health services company of just over 100 persons. The individual I was replacing left the company with little to no notice. Basically, I have inherited a network of one main HQ (where I am situated) which has existed for over 10 years, with five smaller offices (less than 20 persons). I am trying to make sense of the current setup. The network at the HQ includes: Linksys RV082 Router providing internet access for employees and site to site VPN connecting the smaller offices (using an RV042 each). We have both cable and dsl lines connected to balance traffic (however this does not work at all and is not my main concern right now). Cisco Ironport appliance. This is the main gateway for our incoming and outgoing emails. This also has an external IP and internal IP. Lotus domino in and out email servers connected to the mentioned Cisco gateway. These also have an external IP and internal IP. Two windows 2003 and 2008 boxes running as domain controllers with DNS of course. These also have both an external IP and internal IP. Website and web mail servers also on both external and internal IPs. I am still confused as why there are so many servers connected directly to the internet. I am seriously looking to redesign this setup with proper security practices in mind (my highest concern) and am in need of a proper firewall setup for the external/internal servers along with a VPN solution about 50 employees. Budget is not a concern as I have been given some flexibility to purchase necessary solutions. I have been told Cisco ASA appliance may help. Does anyone out in the Server Fault Universe have some recommendations? Thank you all in advance.

• Change Gnome panel profile according to number of displays

  - by ifischer

  I'm running Ubuntu 10.04 on a Laptop. I have a startup script which enables external displays, if they are connected. It runs at GDM startup, configured in /etc/gdm/Init/Default. When i'm running without external displays, Gnome should use 2 Panels. When i'm using 2 external displays, Gnome should add an additional Panel to the second display. But this should of course be removed again if i detach the external displays (and restart). Can i configure this use case by using Gnome Panel-profiles? I read that there is a startup option "--profile" for gnome-panel, but i don't know how and where i could switch the profile, especially because this has to be done after recognizing the number of displays. Or can i add a general Gnome profile and switch between those profiles somehow to achieve this behavior?

• WD My Passport detected but not assigned a drive letter

  - by abel

  I have a WD My Passport external drive which used to work fine on my Win7 x64 box until recently. Since the past few days, windows would not detect my external drive. However, Storage under disk management lists my external drive(which means windows can see my drive) but without a drive letter. I am not able to assign a drive letter(the option is grayed out). I installed EASUS Partition Manager which allows me to assign a drive letter, but fails to do so when I apply to save changes. What do i do to assign a drive letter to the drive or make windows to detect it as of old? The external drive works well on Win7 x32(dual boot, same system) and win7 x64 on another box. Update: cant comment from Opera Mini 6 @zeke the drive works absolutely fine on other Win7 boxes and on the dual boot win7 on the same system.

• Where is custom icon information stored in Mac OS X Snow Leopard?

  - by AmazingRobie

  I have an external Lacie hard drive connected via USB to my Macbook Pro which is running Snow Leopard. I have nothing but music on the external drive with every album sorted in it's own individual folder and have changed all of the individual folder icons to display the album art of the songs from the album inside. I want to reformat my laptop, but I'm afraid if I do that, the album art will disappear if it's stored on a system file within the main hard drive OS. My question is this, is the information which tells the OS to display the album art listed in a hidden system file on the external Lacie drive or my laptop hard drive and if I reformat will I have to reassociate all of the album art to the folders on the external or will it keep it's associations. Thanks in advance.
