• SQL Server on Linux

  - by TimothyAWiseman

  For a particular project that is coming up, I am trying to expand my knowledge of Linux, so I am going to set up a Linux system at home. Rather than dual booting, I am thinking about putting SQL Server on a Windows Virtual Machine with Linux as the host at least until this project is over when I will probably switch back to Linux. So, I have a couple of different, but interrelated questions: How well does this work? This is only a test machine at home, so I can easily accept a fair bit of degradation, but if it is going to be a horrible reduction in performance I will dual boot instead. Is there a particular virtual machine manager I should look at to go this route? Since this is my personal machine, price is an issue but I am quite happy to pay a reasonable amount. And finally, given the choice of VMM, is there a particular Linux Distro I should be looking at? [This has been cross posted at Ask.SqlServerCentral.com . I think it may be appropriate at both sites. ]

• multiple folder structures/views

  - by Sojourner

  Newbie. Setting up a server for a law firm. Want to set up the folder structure as follows: Client 1 Name -- Matter 1 (i.e. setting up corporation) -- Matter 2 (i.e. divorce) -- Matter 3 (i.e. setting up trust) Client 2 Name -- Matter 1 Client 3 Name -- Matter 1 and so on. But the attorneys prefer navigating a folder structure, more based on what case type: Civil -- Client 1 Name (i.e. Smythe) -- Client 2 Name (i.e. Jones) -- Client 3 Name (i.e. Johson) -- Landlord/Tenant -- Client 1 Name (i.e. Jones) -- Client 2 Name (i.e. Johson) -- Class Action Suits -- Suit 1 -- Suit 2 Personal Injury -- Client 1 Name -- Client 2 Name -- Client 3 Name Criminal -- Client 1 Name (i.e. Smythe) I'd like to know if it's possible to set up the server with the first folder structure (it's more organized and easier to employ scripts), while having the second folder structure available for users who find it easier to deal with the same types of cases grouped together.

• Tips on setting up a virtual lab for self-learning networking topics

  - by Harry

  I'm trying to self-learn the following topics on Linux (preferably Fedora): Network programming (using sockets API), especially across proxies and firewalls Proxies (of various kinds like transparent, http, socks...), Firewalls (iptables) and 'basic' Linux security SNAT, DNAT Network admininstration power tools: nc, socat (with all its options), ssh, openssl, etc etc. Now, I know that, ideally, it would be best if I had 'enough' number of physical nodes and physical network equipment (routers, switches, etc) for this self-learning exercise. But, obviously, don't have the budget or the physical space, nor want to be wasteful -- especially, when things could perhaps be simulated/emulated in a Linux environment. I have got one personal workstation, which is a single-homed Fedora desktop with 4GB memory, 200+ GB disk, and a 4-core CPU. I may be able to get 3 to 4 additional low-end Fedora workstations. But all of these -- including mine -- will always remain strictly behind our corporate firewall :-( Now, I know I could use VirtualBox-based virtual nodes, but don't know if there are any better alternatives disk- and memory- footprint-wise. Would you be able to give me some tips or suggestions on how to get started setting up this little budget- and space-constrained 'virtual lab' of mine? For example, how would I create virtual routers? Has someone attempted this sort of thing before: namely, creating a virtual network lab behind a corporate firewall for learning/development/testing purposes? I hope my question is not vague or too open-ended. Basically, right now, I don't know how to best leverage the Linux environment and the various 'goodies' it comes with, and buying physical devices only when it is absolutely necessary.

• OS/X 10.6 Bizarre login bug: Making alternative "Others..." appear. Why does this happen?

  - by bjornl

  I am studying at NUS in Singapore, and they have a mac-equipped computer lab here at school. All users (students) have our own personal accounts that we use to log in to the computers with. Sometimes when you approach a computer to log in only the alternative "thinkmac", which is the school's administrator account, I presume. Some other computers have the alternative "thinkmac" as well as "Others..." where you can input your own login credentials. One day as I sat down by a computer and there was only the "thinkmac" alternative. I was about to get up and find another one when the guy sitting next to me says - Just click 'thinkmac' - the computer will ask for your password - then hit escape to get back to the login screen. Repeat until "Others..." appear. So: If you click any user account, hit ESC to get taken back to the login screen, repeat for 5-10x, eventually the alternative "Others..." will appear. Why is this? Is there an internal counter that keeps track on how many times you have clicked a/any given user account, and after a certain threshold it displays the "Others"? What is the logical reasoning behind this?

• Outlook and IMAP - Outlook doesn't allow the Drafts and Trash folders to sync with the respective IMAP folders

  - by Matt

  I'm using Outlook 2007 and Outlook 2010 against an IMAP server (the problem exists across many, like Gmail, you name it). Outlook lets you set your Outlook "Sent" folder to map to the IMAP server's Sent folder (the other choice is to map your Outlook Sent to your Personal Folders Sent) - this is good. When you send a message from Outlook and then look in the sent folder of the IMAP server (e.g. from a different client or from a browser), the messages are there. This is the behavior I want. Outlook does NOT support the same behavior for Drafts and Trash. In both cases, items deleted (or Drafts saved) in Outlook go in to Outlook's local folders and do NOT show on the IMAP server's Trash or Drafts folders. Same problem in reverse. Thunderbird on the other hand does support the proper mapping of Drafts, Sent and Trash. I expected this to be IMAP-specific but it appears to be client specific. What does Outlook implement it this way and is there a workaround?

• Remote server security: handling compiler tools

  - by Gonzolas

  Hello! I was wondering wether to remove compiler tools (gcc, make, ...) from a remote production server, mainly for security purposes. Background: The server runs a web application on Linux. Consider Apache jailed. Otherwise, only OpenSSHd faces the public network. Of course there is no compiler stuff within the jail, so this is about the actual OS outside of any jails. Here's my personal PRO/CON list (regarding removal) so far: PRO: I had been reading some suggestions to remove compiler tools in order inhibit custom building of trojans etc. from within the host if an attacker attains unpriviliged user permissions. CON: I can't live without Perl/Python and a trojan/whatever could be written in a scripting language like that, anyway, so why bother about removing gcc et al. at all. There is a need to build new Linux kernels as well as some security tools from source directly on the server, because the server runs in 64-bits mode and (to my understanding) I can't (cross-)compile locally/elsewhere due to lack of another 64-bits hardware system. OK, so here are my questions for you: (a) Is my PRO/CON assessment correct? (b) Do you know of other PROs / CONs to removing all compiler tools? Do they weigh in more? (c) Which binaries should I consider dangerous if the given PRO statement holds? Only gcc, or also make, or what else? Should I remove the enitre software packages them come with? (d) Is it OK to just move those binaries to a root-only accessible directory when they are not needed? Or is there a gain in security if I "scp them in" every time? Thank you!

• File sharing for small, distributed, non-technical, non-profit organization?

  - by mnmldave

  Problem: I've started volunteering for a small non-profit with fewer than five non-technical Windows users who need to share 20-30GB of files (Office documents, images, PDFs, etc.) amongst themselves online. Background: The users are accustomed to a Windows network share on a machine that backed up their data locally. An on-site "disaster" has forced them to work from their homes for awhile and to re-evaluate their file sharing needs (office was located in an old building with obvious electrical issues, etc.). Access to time from volunteers with IT experience seems to be difficult. Demonstrably minimizing energy consumption is a nice-to-have. I'm currently considering Jungle Disk (a Desktop account shared amongst the handful of employees since their TOS and my inquiries to their helpdesk seem to indicate this is permissible). It appears easy-to-use, inexpensive, secure, has backup functionality, and can scale to accomodate more data when needed. I've not used it myself though (have only used Dropbox for personal use) and systems isn't my area of expertise, so am worried I might be jumping on a bandwagon. That said, any suggestions, thoughts or similar experiences would be really appreciated.

• Syncronization between folders MAC OS Lion

  - by Andre Carvalho

  I have an iMac at home and I use a Macbook pro for work. I also have a time capsule at home containing my main folder with my main files. I use it as a NAS besides the Time Machine backup tool. I have several personal files I need to be accessing both at home and at work. My wife, who works at home, uses sometimes the same .XLS files and .DOC files I might have used during my day at work, away from home. My question is: Is there a software, or tool that a I can use to sync my iMac and my MB Pro folders? Remembering that: There might be a chance that my wife and I have changed the same files during the day, so the files would have to be merged so none of the information added by either me or my wife would be lost. The software/tool that would be installed on the MB Pro would need to mount the Time Capsule volume so it could locate the main folder on it. It has to be done automatically when my MB is at home ( with a schedule option ); I have tested some softwares like synctwofolders and Chronosync but none fulfilled all my needs. The first couldn't mount the Time Capsule Volume and didn't have the many schedule options. I really liked Chronosync, but it doesn't merge the files. When it detects a conflict ( for instance: my wife changed a .DOC file on the iMAC and I changed the same file on the MB it asks you to choose which version you want to keep instead of allowing you simply to merge them ). I don't have much experience with automator or scripts but maybe you can give me a hand with that.

• Windows 7 libraries and folder redirection nightmare

  - by Lobuno

  Hello! In our active directory we deploy a policy to our clients where the personal directory (My documents) is redirected to a file server of ours \server\share\username\Documents In older systems everything worked fine. in Windows 7 some users are experimenting the following symptoms: The Documents library is EMPTY Where the documents library should be shown in Explorer an empty white icon is displayed. No caption. Right clicking in the Documents library to edit the folders that are part of the libraries brings the dialog up. However, that dialog is unusable. No folder is present there and clicking Add folder does nothing. Deleting the library and auto-creating it doesn't solve the problem The shared directory can be accessed via UNC paths and it can be mounted as a shared drive as well. The library is still broken. The shared drives are on a W2008 indexed server... Using the Windows Library tool utility doesn't solve the problem. What can the cause of this problem be and how can this be solved?

• Port translation in router causing some email to fail

  - by user22037

  We are in the process of setting up a spam filter (SAVASM). One change we are making is to push incoming email on port 25 through our spam filter/server but have users actually send their email on a different port. I am attempting to make this happen by using port address translation to send port 25 traffic to the SAVASM server IP. As a step in making this change I setup port translation without actually changing the IP addresses. The NAT rules for the email server went from one Static NAT rule with no port specified, to multiple Static NAT rules each with a port or group matching the Access Rules for that server (smtp, pop3, http, https, and some other custom ports). The problem we are running into is confusing. Some outgoing mail through this server is failing when the router has the multiple NAT rules with port translation settings. Email goes through fine FROM our email to our internal accounts and to Gmail. However email fails when FROM our client's email address TO our client's email or their personal Comcast. The only situation that worked for them was if they changed FROM to Comcast and then messages went through fine to both Comcast and the client's accounts. Switching back to regular Static NAT rule everything then worked for them. Does anyone have a clue as to what might be going on? We are on a Cisco ASA 5500 box.

• Hard drive failed, suspected filesystem corruption, still cannot salvage any data from harddrive

  - by Hippy-Head

  Firstly, I am terribly sorry if this is a duplicate, but I couldn't find a similar issue to mine, so here goes. I have a 1TB hdd bought around 8 months ago used as backup hard drive. I have not used the drive for a period of time whatsoever, and when I was trying to get back to some files on it, it was completely wiped just like that. At first it would not boot I tried everything from command line chkdsk and filesystem recovery software to rebuilt it. After a few attempts I managed to initialize it, at that time it was an achievement. The problems started when I tried to recover the data inside, I have used A LOT of software free and commercial software on both Mac and Windows, with the help of cmd or Terminal commands, however no data of any kind was recovered, even after leaving it thoroughly scan for around 9-10 hours all night sometimes longer, with no results at all. I am somewhat desperate, I am usually good at retrieving data from corrupt hard drives, but this is not the case. Call me paranoid, but I do not want to give it to someone to fix it for me, as I have a lot of photos and personal stuff that I do not want anyone to see.

• Help Email Account Management among multiple users

  - by CogitoErgoSum

  So I preface this with saying this may belong in IT Security, not too sure feel free to move. Currently we have an email account [email protected] - hosted via google apps (as is all our email). We had an incident where we had to terminate an employee. This employee however had the password for this account as we have 20-30 people utilizing it at any given point to manage customer emails etc. Thinking on this I feel there must be a better way to manage access. With Google you can associate upto 10 email accounts to another the problem is we have more like 20-30 people going. We were evaluating tools such as SalesForce and Assistly where people have their own login credentials and then the system contains the appropriate smtp information for the [email protected] email address to send emails from it rather than a users personal account. Aside from those options does anyone have any other thoughts? One suggestion floated was moving everyone to desktop clients and saving the PW info there so they could only login from their physical workstation but we may have situations where we'd like employees to work remotely. Does anyone have experience with this sort of system where ~20-30 people are responding from one email box and how to manage security and access?

• RAID 5 Install on Ubuntu Server 12.04 [closed]

  - by tarabyte

  Environment: Ubuntu Server 12.04, installing from bootable flash drive Error: No root file system is defined. Please correct this from the partitioning menu. I'm trying to set up a personal file server with software RAID 5. I just got three hard drives for this, but haven't found any solid documentation. I'm unsure what the basic way to partition my hard drives is. Can someone upload a screenshot of their "partition disks" screen so that I can compare with mine (attached)? Should I set the bootable flag? Do I need a /home partition? A /boot partition? Should I "Use [my partition] as: Ext4 journaling file system"? Or make that field "physical volume for RAID"? I am an engineer, but I have only a cursory knowledge of all-things-linux. If you know of any good learning resources I'd be happy to hear about those too (that way I don't have to blindly follow deprecated tutorials online). well, image would be here but i don't have a high enough reputation yet (please vote up :)) Thank you, References I've looked into: https://help.ubuntu.com/community/Installation/SoftwareRAID https://help.ubuntu.com/12.04/serverguide/advanced-installation.html http://forevergeeks.com/setup-ubuntu-server-with-raid-5/

• Best CPUs for speeding up compiling times of C++ w/ DistGCC

  - by Jay

  I'm putting together a distributed build farm with DistGCC to speed up our teams compile times and just looking for thoughts on which processors to use in the hosts. Are we going to get a noticeable decrease in time using 8 cores vs. 4-hyperthreaded cores? Big difference in time between i7 and Xeon? etc, etc. Just need advice from people who've put together kick-a build clusters. We've got a majority of the normal things to speed up builds in place (pre-compiled headers, ccache, local gigabit connections between them, tons of ram, etc) so please just give advice on the best processor to use. And money is a factor, but anythings doable if the performance increase is noticeable. Thanks. Jay EDIT: Although any advice IS welcome, please refrain from "Do this first" posts as we're not planning on skimping on things like SSD, maxed out RAM, etc. My personal system is a iMac Quad-core i5 with 8GB of RAM. When I build our project locally, my processor floats around 99-100% a majority of the time, which makes me assume it is a bottleneck, even if you made everything else faster. My ram on the other hand doesn't even get close to maxing out. It's also worth noting that I did research this, however every discussion I could find was primarily for gaming machines, which is obviously a different beast in usage. These machines won't even have monitors or anything but integrated graphics since they have one purpose: Build freakin fast. (hopefully)

• How can I disable the CTRL-ALT-DEL key combination completely on XP/Vista/7?

  - by Travesty3

  I have been googling extensively to figure this out, and nobody seems to be able to give a direct answer. Let me start by saying that I'm NOT talking about requiring CTRL-ALT-DEL to enter logon information. I'm working on a golf simulator program which is used at golf centers. I need the ability to completely disable the CTRL-ALT-DEL key sequence so that the golf center customers can't get out of the program and access the computer at all. I realize there are other key combinations that need to be handled as well, we already have this entire feature working in XP, but we're going to be switching to Windows 7 soon, and CTRL-ALT-DEL is the only one that doesn't seem to work in Win7. I'd really like an all-around solution if at all possible. This same program may also be installed on a client's personal computer for an in-home golf simulator, but the computers that really need this feature (golf center computers) are provided to the golf center by us, so would the best option be to write a new shell? I don't know anything about that at all, other than others that suggest writing a new shell for kiosk mode. I'd really like a simpler option, like modifying the registry in some way. I have heard that you can remove some buttons from the menu screen that pops up, but unless I can remove pretty much all of them (including the shutdown/restart button in the bottom-right corner), this won't be enough of a solution for me. Thanks for taking the time to read this and thanks again for any help you could provide! -Travis

• How do I determine whether this email bounce is my fault?

  - by David Zaslavsky

  I use Google Apps to handle email for my personal website, so I have an email address [email protected] through that, and I also have a Gmail account [email protected]. Now, I've been trying to send emails to a particular recipient who shall be known as [email protected]. When I send the email from my Gmail account with the @gmail.com address, it works fine. However, when I send it from my Google Apps account with the @ellipsix.net address, I get a bounce message which includes the following text: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 mail server permanently rejected message (#5.3.0) (state 17). The bounce message suggests that it is up to the mail administrator of the recipient domain example.com to fix the problem, whatever it is. But I would like to be as sure as possible that nothing needs to be fixed on my end. I already have DKIM signatures enabled for my domain, and I have published an SPF DNS record. Is there something else I should check or do, or can I be confident that it's up to the recipient to fix this issue? Does the "state 17" in the bounce message mean something relevant? I've included my domain name in the question so people who know more than me about this stuff can independently check the relevant DNS records or other information. This other question seems similar, but I've already investigated everything suggested in the answers there (except for contacting Google, which I don't want to do unless I suspect it's their issue to fix).

• Improving abysmal 802.11n wireless network

• Why can a local root turn into any LDAP user?

  - by Daniel Gollás

  I know this has been asked here before, but I am not satisfied with the answers and don't know if it's ok to revive and hijack an older question. We have workstations that authenticate users on an LDAP server. However, the local root user can su into any LDAP user without needing a password. From my perspective this sounds like a huge security problem that I would hope could be avoided at the server level. I can imagine the following scenario where a user can impersonate another and don't know how to prevent it: UserA has limited permissions, but can log into a company workstation using their LDAP password. They can cat /etc/ldap.conf and figure out the LDAP server's address and can ifconfig to check out their own IP address. (This is just an example of how to get the LDAP address, I don't think that is usually a secret and obscurity is not hard to overcome) UserA takes out their own personal laptop, configures authentication and network interfaces to match the company workstation and plugs in the network cable from the workstation to their laptop, boots and logs in as local root (it's his laptop, so he has local root) As root, they su into any other user on LDAP that may or may not have more permissions (without needing a password!), but at the very least, they can impersonate that user without any problem. The other answers on here say that this is normal UNIX behavior, but it sounds really insecure. Can the impersonated user act as that user on an NFS mount for example? (the laptop even has the same IP address). I know they won't be able to act as root on a remote machine, but they can still be any other user they want! There must be a way to prevent this on the LDAP server level right? Or maybe at the NFS server level? Is there some part of the process that I'm missing that actually prevents this? Thanks!!

• How to Refresh or Reset Windows 8 without the System Reserved partition?

  - by Karan

  The article Refresh and reset your PC mentions exactly what happens during the refresh and reset operations in Windows 8: Refresh The PC boots into Windows RE. Windows RE scans the hard drive for your data, settings, and apps, and puts them aside (on the same drive). Windows RE installs a fresh copy of Windows. Windows RE restores the data, settings, and apps it has set aside into the newly installed copy of Windows. The PC restarts into the newly installed copy of Windows. Reset The PC boots into the Windows Recovery Environment (Windows RE). Windows RE erases and formats the hard drive partitions on which Windows and personal data reside. Windows RE installs a fresh copy of Windows. The PC restarts into the newly installed copy of Windows. It is my understanding that Windows RE (Recovery Environment) is included as part of the System Reserved partition created by default on the first hard disk. The size of this partition has gone up to 350 MB from the 100 MB it used to be in Vista/Windows 7, no doubt as a result of adding these features. Now we have already discussed how to skip the creation of this System Reserved partition during Setup. Basically, the same techniques that used to work with Windows 7 work with Windows 8 as well. What I want to know is, what will be the exact repercussions of not having the System Reserved partition in place? I assume Troubleshoot / Advanced options should still be available as before: But what about the Troubleshoot menu itself? Will the Refresh and Reset options disappear? Will they remain but be unavailable? Or possibly they will throw an error if selected? Also, will it be possible to access and successfully execute these options if installation media is available? Anything else that might be affected?

• VPS with Plesk, one ip, and godaddy (definely need help)

  Hi there, here's my situation : i've Plesk 8.3.0 with one IP and i've registered my domains at godaddy.com My problem : i cannot figure out how to configure plesk and godaddy to have my domains (6) properly working into the VPS. i've only one IP, so i can't have my personal NS and need to use godaddy ns. But.. how do i set all the stuff ? I've made a try but it's not working. Please take a look : This is an example of how the domain i'm actually working on is configured On Plesk : Host Record type Value 1.2.3.4 / 24 PTR mydomain.com. ftp.mydomain.com. CNAME mydomain.com. mail.mydomain.com. A 1.2.3.4 ns.mydomain.com. A 1.2.3.4 mydomain.com. NS ns.mydomain.com. mydomain.com. A 1.2.3.4 mydomain.com. MX (10) mail.mydomain.com. webmail.mydomain.com. A 1.2.3.4 www.mydomain.com. CNAME mydomain.com. On godaddy,(Total DNS Control) for the same domain i have this setup : A (Host) Host Points To TTL Actions * 1.2.3.4 1 Hour CNAMES (Aliases) Host Points To TTL Actions e email.secureserver.net 1 Hour email email.secureserver.net 1 Hour ftp @ 1 Hour imap imap.secureserver.net 1 Hour mail pop.secureserver.net 1 Hour mobilemail mobilemail-v01.prod.mesa1.secureserver.net 1 Hour pda mobilemail-v01.prod.mesa1.secureserver.net 1 Hour pop pop.secureserver.net 1 Hour smtp smtp.secureserver.net 1 Hour webmail webmail.secureserver.net 1 Hour www @ 1 Hour MX (Mail Exchange) Priority Host Goes To TTL Actions 10 @ mailstore1.secureserver.net 1 Hour 0 @ smtp.secureserver.net Host Points To TTL Actions @ ns53.domaincontrol.com @ ns54.domaincontrol.com What should i correct ? Thanks for helping me Francesco

• Intermittent CNAME forwarding

  - by Godric Seer

  I host a personal website on an old desktop that is LAMP based. Since I have a dynamic IP, I use no-ip to make sure I have a working domain name at all times. I also have a domain I have bought on GoDaddy where I have a CNAME record forwarding the www subdomain to my no-ip domain. At all times, I can connect to my website through the no-ip domain without issue. For the past several weeks, I never had an issue using the GoDaddy domain to connect (ssh or https). As of today, however, the GoDaddy domain only works for about 10 minutes at a time. I get server not found errors most of the time. Also, if I happen to be using the GoDaddy domain for an ssh connection, the connection will freeze. I have attempted to run tests using a couple of online DNS check websites, but have not gotten any errors at any time. I also contacted GoDaddy support but they had no issues connecting to the website, and therefore did not see any issues. I would like advice on how I could debug/resolve this issue. Since the problem appeared without me changing anything on my end, I hope it will resolve itself, but knowing the cause in case it happens again would be preferable. EDIT: I changed the configuration in GoDaddy to create an A (Host) that points at my current IP. This works fine, so I can access the site through the GoDaddy domain without the preceding www. I am currently waiting for a new CNAME record to propagate that points the www subdomain at the main host, rather than my no-ip domain.

• Can you share offline files cache with two user accounts?

  - by Joel Coehoorn

  I have a new laptop that I use for both home and work. It runs windows 7 ultimate, and is joined to the domain at work. It is okay to use this laptop for both work and personal activities, and I even have an account set up on the local machine in addition to the work domain account specifically for this to help keep the two separate. At home, I have a file server that I use to share files and printers with my wife's laptop, this new laptop, and my old desktop which will now become the family machine. My mp3 library is on there, among other things. What I want to do is use the windows Offline Files feature to keep a synced copy of my music library on the laptop. That part is easy. What's tricky is that I want to share this offline cache between both the local account on the laptop and my work domain account. I could do them both separately, but then I have two copies of a very large music library stored locally. This also means twice the sync burden, when the domain account is rarely connected to the file share. I really want to be able to sync from the local machine account only, and have the domain account be able to use the synced files. I know where the offline file cache is kept (\Windows\CSC) and I can find the cached files (not encrypted), but permissions on the cache are setup weird, and so using that cache directly is not trivial. Any ideas appreciated.
