  I installed barnyard2 and saved as a service. When I run service barnyard2 start, Barnyard2 is failed. After I run tail -100 /var/log/messages and I encounter a fault like this.

• Is there a way to force Windows to recognize a network folder as a local drive, for the purposes of

  - by NoCatharsis

  I just started using the file search program Everything at work to search through documentation on our shared drives. This is after disappointments with Google Desktop and Windows Search. I love the speed of Everything, but I wish it were able to index other shared folders. My makeshift solution was to somehow force Windows to recognize the necessary shared folders as local drives, then add them to the index list. I have also considered using SyncToy, but this requires downloading all data to my drive, which could be terabytes of information - obviously not a good idea on a small company network. What would be the best solution here?

• How do I create email addresses for all my users using my domain ([email protected])?

  - by user33012

  My client wants to create email addresses for all their dotnetnuke users using their domain. The point is to keep the user's email addresses 'private' while still allowing communication through a public email address that they can control. It's not necessary to have a full webmail interface (although that would be nice). I'm thinking it would be enough just to forward any mail on and just act as a gateway. So if an email was sent to [email protected], it would be forwarded on to the email address associated with the dotnetnuke account with username 'rwain'. Is this possible to do in a shared hosting environment? Or do I need to create some custom mail server that does a conversion of the email address and forwards it?

• Managing Windows 7 Workstations

  - by ethamoose

  There was a similar thread to this a few years back, but without any solutions. Just wondering if things have moved on since then. I'm primarily an Mac admin working in a college, but I have recently taken over responsibility for about 30 student workstations running Windows 7. For the Macs I have Apple Remote Desktop, where I can logon to machines in a session,check for any nefarious student activity and if necessary, log off or lock users out of machines. Could anyone give me a suggestion for an equivalent Windows system manager where I can do these tasks - e.g. not just a vnc client but one with more management options?

• Publish database between two open database connections (Visual Studio 2005)

  - by danielswe

  I have two data locations, one to a local and one to a remote database. How do I copy the local database schema to the remote? The reason I don't use "Publish to provider" is that I'm not sure that I have all the information necessary to do so. I have the database name, server, username and pass but not "web service address" nor "web service password". I work in Visual Studio 2005. The server is a MSSQL 2005 server. I have tried using the queries but I only get errors doing so.

• how to switch played music when someone enters

  - by ymajoros

  My wife has a small shop, and she plays free licensed music. She can't legally play her own music when people outside of the family circle are present in the shop. How can I automatically switch music when someone enters? I was thinking of some bluetooth door detector and some custom software, but can't seem to find either. I'm a software architect/dev and can write it if necessary, but I'd prefer to use some existing solution. Any ideas on good hardware and software for this?

• Restart an in-use NFS server without interruption (within timeout)

  - by zebediah49

  I have a bunch of compute clients working on jobs, saving output data to a NAS machine. All machines are centos 6.2. They mount it via automount NFS, with a timeout of 1200 (default config). The NAS machine needs to be restarted. If I can restart the machine within that 1200s (20 minute) window, will the clients just block on IO until it comes back up? A minor interruption (pause) in service is ok, as long as it doesn't cause the running processes to error out. If necessary I could loop through and SIGSTOP all job processes, restart and resume them -- I just don't want to break the open file handles. How can I run a restart like this without killing processes with open files?

• Setting up a transparent proxy with only one box.

  - by Scott Chamberlain

  I am playing around with transparent proxies, unfortunately I do not have two machines to test it out with. The current way I am doing things is the program makes a request to a computer on port 80, I use iptables -t nat -A OUTPUT -p tcp --destination-port 80 -j REDIRECT --to-port 1234 to redirect to my proxy that I am playing with. the proxy will send out a request to port 81 (as all outbound port 80 are being fed back in to the proxy so I want to do something like iptables -t nat -A OUTPUT -p tcp --destination-port 81 -j DNAT --to-destination xxxx:80 The problem lies with the xxxx part. How do I change the destination port without changing changing the destination ip? Or am I doing this setup completely wrong, I am learning after all and constructive criticism is definitely appreciated. The machine I am using is pretty low end so I would like not not have to create a VM with a second box unless absolutely necessary.

• Running commands on FreeBSD Live CD

  - by jmc

  I'm running FreeBSD 9.1-PRERELEASE on a vps running on XEN virtualization, I tried to update it to 9.1-RELEASE but mergemaster toasted my /etc/master.passwd and /etc/passwd so what i have now is a blank copies of the two files. What i did is use a mounted Live CD and mount my root partition to /mnt and manually re listed every entry to /mnt/etc/master.passwd and /mnt/etc/passwd from another freebsd server. I believe that everytime you edit master.passwd and passwd you have to run pwd_mkdb but this gives me "Read Only File" error. What I plan to do is enable PermitRootLogin and PermitEmptyPassword first so I can login as root first before I redo necessary changes again. But i have to run pwd_mkdb, so is there a way to run this command from Live CD?

• AD Local Admins without password sharing

  - by Cocoabean

  My team is building out an Active Directory environment in a small grad school with support for general computer labs, and staff/faculty machine and account management. We have a team of student consultants that are hired to do general help desk work. As of now we have a local admin account on every machine. It has the same password and all of us know it. I know it's not best practice and I want to avoid this with the new setup. We want to have local admin accounts in case there are network issues that prevent AD authentication, but we do not want this account to be generic with a shared password. Is there a way we can get each machine to cache the necessary information to authenticate a group of local admins so that if AD is somehow inaccessible, student consultants can still login with their AD admin accounts?

• What is the world wide web? [closed]

  - by think123

  I don't know where to post this question, so please move it if necessary. Ok, so I've heard of how the professional hosting companies can create 'links' to the world wide web to register an unregistered domain. So that's where my question comes from. Is the world wide web a server to which servers link? Is it created by abstract linkage? I'm not sure. Also, what does it mean for the DNS to be updated throughout the whole world?

• determine the archetecture of a mac from the command line or script?

  - by Brian Postow

  I'm writing a shell script, and I need to know the archetecture, ie PPC or Intel. Back in the day, there was a program /bin/arch that told you, but my mac doesn't seem to have it... Is there an easy way I can do this? Grep for something in a logfile? call some other program that spits that out as a side effect? It would be nice to know what OS Version I'm running too, but that may not be necessary. thanks

• Can I install fresh Linux accross partitions (LUKS & LVM) and preserve/use existing home user?

  - by xtian

  With an existing LUKS encrypted logical volume partitioned hard disk dual boot to Windoz and Linux (Fedora 15), is it necessary to "start over" with the LUKS setup when upgrading the system? I recall some note about dividing the Linux installation over different partitions would help to preserve the home data in future update (I can't find this now) Before I try it, is this possible and intended use case for partitioning a Linux installation? # lsblk -fa NAME FSTYPE LABEL MOUNTPOINT sda [80G] +-sda1 [system W95 FAT 32] vfat +-sda2 ext4 /boot +-sda3 [52.4G] crypto_LUKS +-luks-de25ac97-6a32-4b79-a6a0-296a39376b3b (dm-0) LVM2_member +-cryptVG-root (dm-1) [21.5G] ext4 / +-cryptVG-swap (dm-2) [5.4MB] swap [SWAP] +-cryptVG-data (dm-3) [25.6G] ext4 /home

• Make user uploads go to different hard drive?

• Apache: Stealth 404 the admin area until authenticated via basic auth, then allow access

  - by Kzqai

  Given a administrative area with urls like this: wp-admin/ wp-admin/whatever wp-admin/another-page wp-adminsecretlogin/ A standard basic-auth coverage would provide a username and password prompt on all three urls, and return a 403 on all failed auth attempts. This is a pretty obvious signal that something exists there, and thus is an invitation to script/brute force access. I would like to instead, require basic auth everywhere, but when not authenticated, not prompt for username and password, and instead return a 404 not found error for all urls except a wp-adminsecretlogin/ url. At that individual-to-the-site url, basic auth could go through, and unlock the rest of the administrative functionality (though the standard application login would still be necessary). How would I do that via apache .htaccess or .conf directives?

• Postfix cleanup daemon access control

  - by Flimzy

  Is there any way to control which hosts are permitted to connect to the cleanup daemon over TCP? Our 'master.cf' contains: 2526 inet n - - - 0 cleanup This is necessary because we have a cluster of SMTP servers running custom code, and they can all inject mail to the centralized postfix server via the cleanup daemon. However, we want to allow only our authorized servers to connect to the cleanup daemon. The current configuration allows any host to connect to port 2526. Clearly we can use iptables to restrict access, but is there a way to do this within postfix itself?

• Does it make a difference to read from a file instead of from MySQL?

  - by Joe Huang

  My web server currently is quite loaded. And I have a PHP file that is accessed very often remotely. The PHP file basically makes a MySQL query and returns a JSON formatted string. I am thinking to use a Cron job to write the necessary data into a file every 15 mins, so the PHP file doesn't make a MySQL query, instead it reads from the file. Does it make a difference? I mean to alleviate the server loading (CPU/MySQL) a bit?

• Partition and mount my secondary hard drive on CentOS 5.5 64bit?

  - by Andrew Fashion

  I am trying to prepare my second hard drive for user image uploads. Here is the current layout: # sudo parted /dev/sda print Model: ATA WDC WD2500KS-00M (scsi) Disk /dev/sda: 250GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 107MB 107MB primary ext3 boot 2 107MB 8595MB 8488MB primary linux-swap 3 8595MB 10.7GB 2147MB primary ext3 4 10.7GB 250GB 239GB extended 5 10.7GB 250GB 239GB logical ext3 Information: Don't forget to update /etc/fstab, if necessary. I am assuming #4 is my secondary drive? How do I partition and mount it so I can begin using it? And how do I add to fstab? I understand if it's to many questions in one, just help me with whatever you can I guess :) Thank you for any help!

• Does a modern PC require a graphics card to run?

  - by ArtM

  As I can remember, on old systems (Pentium II or III) it was not possible to boot and run the PC if the graphics card was missing (AGP cards were used in those days). Many years from then, I'm using motherboards with integrated graphics and I have no experience related to this subject, the "graphics card" always was present. Currently I intend to build a home/private "server" for my purposes and most of the motherboards I want to buy have no integrated graphics (AMD 870 or 970). I can take a normal graphics card from my firends for a few hours/days and use it when installing the necessary software. The question is: can I boot and run the PC without problems after I install everything I need and the graphics card is removed? if a general answer cannot be given, at least some examples of manufacturers/MB series/MB models will be helpfull I think it's obvious, but for completeness: I mean cheap desktop components, not real servers.

I can add two squids if it is necessary. Thanks a lot.

• Any need to make backup of data on Amazon S3?

  - by Chrille

  I'm hosting 200 GB of product images at S3 (this is my primary file host). Do I need to back that data up somewhere else, or is S3 safe as it is? I have been experimenting with mounting the S3 bucket to a EC2 instance, and then making a nightly rsync backup. The problem is that it's about 3 million files, so it takes a while to generate the different rsync needs. The backup actually takes about 3 days to complete. Any ideas how to do this better? (if it's even necessary?)

• Shared Exchange Calendar View

  - by Mark A Johnson

  My department creates a shared calendar for everyone to enter their out-of-office times. This requires duplicate entry for those of us who keep all our info in our own Exchange calendar. Is there a way in Exchange to create a View that's simply a combination view of multiple users' calendars? For example, we would create a view with all the departments' users calendars combined, but only those marked "out of office". Ideally, the subject line would also include the user's name, but this would not be 100% necessary.

• Why is `cmd /C` living after it did its job?

  - by acidzombie24

  My question is why does "cmd" exist (idle) in my process after i update my exe? In my code i run this code to update myself and launch var args = string.Format(@"/C ping 1.1.1.1 -n 1 -w 3000 & move /Y ""{0}"" ""{1}"" & ""{1}"" {2}", updateFn, fn, exeargs); new Process() { StartInfo = new ProcessStartInfo(@"cmd", args) { CreateNoWindow = true, UseShellExecute = false } }.Start(); Environment.Exit(0); The idea is i exit right away and have ping stall for 3seconds before trying to replace my current exe with my updated exe. Then i launch with the necessary args The full arg for cmd looks like this /C ping 1.1.1.1 -n 1 -w 3000 & move /Y "c:\path\update" "c:\path\my.exe" & "c:\path\my.exe" exeargs Everything works fine however i see cmd in the taskmanager (looks to be idle) after my process is launched and correctly working. Why?
