• backup and file server for 50+ TB of data

  - by a-bomb

  our office wants to build a new server to handle our data, over the last 10 years our data was stored on CDs, DVDs, HDDs but now they want all of it in one place that is attached to the network for everybody in the office to access it. the data is 20TB new data and the rest is old, the important now is to store these 20tb and gradually store the other 30tb over time. so what is the best solution to do ? we thought of getting an hp server and connect it to an external enclosure that either had tape drives or HDDs (we haven;t decided yet) or to get a NAS server and connect it to the hp server. what should we do because this is new for us ...

• Backing up Windows 2003 Server that has Certificate Authority

  - by Dina

  I want to export and migrate a Certificate Authority CA role from a Windows 2003 machine to a new copy of Windows 2008 R2 virtual machine. I was told that I cannot have 2 CA roles on the same network at the same time. Therefore, I must first export the certificates on the older machine, delete the CA role, then add the CA role on the new machine and import the certificates into it. As a safety precaution, I am tasked to find a backup solution in case this does not work and I need to revert back to the old Windows 2003 CA. My question is: What is the best software for doing this type of backup? I am currently trying out Symantec Backup Exec 2012. Which I hope will allow me to create a backup prior to removing CA role on Windows 2003. If this CA migration fails, the backup will allow me to revert the old machine to a time before I removed its CA role.

• debian hang on startup "starting the winbind daemon: winbind"

  - by Bajingan Keparat

  I took a copy of a VM running a debian, just so that I can play around with it. I spin up the copy, but didn't give it any network connection to avoid conflict with the original one. However, when I turn the VM on, it seems to freeze after this startup message Starting Sambe daemons:nmbd smbd Starting PostgreSQL 8.4 database server: main Starting the Winbind daemon: winbind how do i fix this? I never get to the prompt to login. This vm does have a mount point that connects to a windows share folder.

• FTP error when doing file transfer

  - by Ernie

  I'm running vsftpd version 3.0.2 over FTPeS, and I'm having a bit of trouble with file transfers. It seems to work fine when I'm on the LAN, but not from an external IP address. I have the control port and data ports open on my server's software firewall and my router's firewall. When I'm using the service from an external IP address, it seems like sometimes a file transfer will complete, but it times out and I always get the client error: "426 Failure writing network stream". I've tried several clients. I'm thinking there is some sort of data sabotage either at the router or some server policy; maybe because I'm using passive ftp? Suggestions?

• Windows Vista: TCP/IP stack is smashed, how to reinstall the LAN-Devices?

  - by Ice

  the TCP/IP stack is smashed, thats why no LAN-Connections are running. I want to download the LAN drivers from another computer and uninstall and reinstall the LAN devices on this system. Hopefully that should recreate the stack. But what to download? What uninstall? How to install? Windows Vista is protected against such changes, so how to achieve that job? please help. Update per 2011-03-11: I found all the tipps and hints about "TCP/IP Repair, LSP Fix, and WinSock Fix" according to windows vista but nothing helped to bring back network access. What can i do as next step or which opportunities are left?

• Can a named (bind) crash make a server unreachable?

  - by giorgio79

  My server recently became unreachable, and after restart a named error was the last line I found in /var/log/messages before restart: Jun 26 00:15:06 host named[1303]: error (network unreachable) resolving 'dlv.isc.org/DNSKEY/IN': 2001:500:71::29#53 Jun 26 06:38:55 host kernel: imklog 5.8.10, log source = /proc/kmsg started.

I doubt it, as I assume I should still be able to login with ssh via IP, but the server did not respond...So, I am trying to make heavy guesses here.

• Bound external Cisco CIGESM ports to a specific BladeServer

  - by Vinícius Ferrão

  We have an IBM BladeCenter with 14 blade servers and one external Cisco CIGESM for Ethernet connectivity. Since this hardware is a little old, we will use it for other services, and we want to run a pfSense instance on one of the blades. It's just an Firewall Appliance, but it needs two network interfaces: one for the WAN and the other one for LAN access. Our architecture works on top of static routes, we don't use NAT, so we got the WAN IP in one interface routing to the another one. The main problem is how to plug the WAN cable in one of the four external ports and make it exclusive to the blade server containing the firewall. And we also need an exit port that goes through a 3COM 4200G switch that makes the internal routing and VLAN separation. Thanks in advance

• Flash Media Server slow over SSL

  - by Antilogic

  We are using FMS to host a VoD site. We host FMS internally (we do not use a CDN). We recently installed an SSL certificate to alleviate connection issues for clients (they're networks either block or don't support RTMP), however we're noticing that when streaming in RTMPS connections are drastically slower (on the order of Mbps). I know SSL causes some amount of over head but both client and server show almost no signs of exertion. Speedtest.net and a locally hosted speed test confirm that bandwidth is not an issue. I'm really not a network guru, so I'm at a loss as to where to check next. Do any of you have an idea why streaming media would run so slow over SSL?

• Sync Banshee library data.

  - by Dom

  I use Banshee to organise my music, I particularly like its scoring system and I have smart playlists based on it. However, I have two versions of my music library, one on each of my computers. As one of the computers is small I only have a favourite set of songs on that computer rather than my whole collection. The computers are not on a local network, but I do use Ubuntu One for file sharing between them. Is there any way I can synchronise song data (play count, score, skip count ...) and playlist data (including smart playlists that include songs based on this data) between the two computers? This would only be relevant of course for the songs that exist on both computers, the songs that exist on only one would need to be ignored. I did consider putting the library data file (I think it is .xml but I'm not sure) into the shared file and creating a symbolic link to it, but then I wouldn't be able to have a different set of songs on each computer. Thank you.

• Sorting IPv4 Addresses

  - by Kumba

  So I've run into a quandary on sorting IPv4 addresses, and didn't know if there was a set rule in some obscure networking document. Do I do a straight sort on the raw address only (such as converting the IP address to a 32bit number and then sorting), do I factor in the CIDR via some mathematical formula, do I sort via the CIDR only (as if I'm comparing the network size and not the addresses directly)? I.e., normal math, we'd do something like -1 < 0 < 1 to denote the order of precedence. Given say, 10.1.0.0/16, 172.16.0.0/12, 192.168.1.0/24, and 192.168.1.42, what would be the order of precedence?

• Is the Alternate Ubuntu installer still required for LVM or Software RAID setup?

  - by jimp

  Over the past 5 years, I have been setting up Ubuntu servers using the Alternate installer. I need to provision a new server today, and I'm curious if the Alternate CD is still the only way to setup LVM/RAID at installation time. I'm my limited experience with Red Hat Enterprise Linux, I noticed it's single installer configures LVM automatically. Has Ubuntu's installer, at least the standard "Server" installer, added support for LVM/RAID, or is the Alternate installer still required for that kind of server setup? http://mirror.anl.gov/pub/ubuntu-iso/DVDs/ubuntu/12.04.1/release/ Alternate install CD The alternate install CD allows you to perform certain specialist installations of Ubuntu. It provides for the following situations: setting up automated deployments; upgrading from older installations without network access; LVM and/or RAID partitioning; installs on systems with less than about 384MiB of RAM (although note that low-memory systems may not be able to run a full desktop environment reasonably). LVM has always been fundamental for our server needs, so I'm surprised if it is still not considered a server-worthy feature.

• Dhcp clients fail after successful import of server to new machine

  - by Tathagata

  I transfered the configs of a dhcp server from one server to another both running Windows Server 2003 R2 following http [://] support.microsoft.com/kb/325473. The new server has a statically configured ip(outside the scope) like the old one. Stopped the server on the old, and started up in the new server (authorized too) - but when I ipconfig /renew from a client its network interface fails with all 0.0.0.0 (or 169...*). I read somewhere I need to reconcile the scope to sync the new registry values ('ll try this tomorrow). What other troubleshooting steps can I take other than these (which didn't help)? Things work fine when the old server resurrects and the new one is taken down. The new server showed there was no requests for offer.

• How do I rewrite *.example.com to www.example.com?

  - by Lekensteyn

  In my network, I've some Ubuntu machines which need to download files from nl.archive.ubuntu.com. Since it's quite a waste of time to download everything multiple times, I've setup a squid proxy for caching the data. Another use for this proxy was rewriting requests for archive.ubuntu.com or *.archive.ubuntu.com to nl.archive.ubuntu.com because this mirror is faster than the US mirrors. This has worked quite well, but after a recent install of my caching machine, the configuration was lost. I remember having a separate perl program for handling this rewrite. How do I setup such a squid proxy which rewrites the host *.example.com to www.example.com and cache the result of the latter?

• cygwin rsync over ssh very slow

  - by Waleed Hamra

  I have 2 machines running Windows Xp SP3. I have cygwin installed on both, version 1.7. I have rsync and ssh installed on both, and configured using default settings as per ssh-host-config and ssh-user-config programs provided. I moved the public keys into their respective locations, and basically ssh is working fine. i began an rsync operation, using: rsync -av --delete --hard-links local_dir username@other_machine:/some_dir well... on both machines, the processor is running near idle, no heavy usage. I checked IO using process explorer on both machines, and that too is at normal levels (1~2 MB/s), so I can't see where the bottlenecks are, because network performance is aweful. I'm not going over 1MB/s... when a normal file copy using windows sharing achieves some ~10 MB/s.. What could be wrong?

• Small business VPN solution

  - by Crash893

  I've been looking for a while but I'd like to to implement a vpn solution for anywhere from 1-5 employees at a time (possibly 10 in a year or so) edit: Basically I would like outside users to fire up a client or open a web page and be able to access things inside the company network (share drives / printers/ webapps /etc) I've looked at Astaro Gateway but im not sure if that's the right tool for the job. I know "best" is a subjective term so i would like to break it into to different suggestions 1) what is the cheapest solution given the criteria above 2) what solution will result in the least amount of headaches from the point of view of maintenance and learning curve.

• Storage setup for large files

  - by Mecca

  I need to store over 200TB of data (all types, biggest being video files) and be able to access it over a local network. The files will be accessed for editing or searches. I don't need versioning, but a setup that would keep me safe from harddrive failures would be nice. Right now the content is on different harddrives, some external drives, some regular. I don't exclude the possibility of buying new/extra drives if necessary. If they will ever be exposed to the web, it wont be to the public, but just a couple of people. I have no idea what to buy to make this happen. I see some NAS solutions over the internet like this http://www.bestbuy.com/site/a/2266043.p?id=1218317764591&skuId=2266043 but the storage is not enough, plus it doesn't seem to be scalable. What do you recommend? Thanks

• Password Expired on Server 2008 R2

  - by Shaharyar

  Hello everybody, We're facing some trouble with our Windows Server 2008 R2 installation. The passwords expired and we're prompted to change the password. After changing it, we get following error message: Configuration Information could no be read from the domain controller, either because the machine is unavailable, or access has been denied. But we aren't even using a domain controller. So we tried running the server in Safe Mode where we get following message after changing the password: An attempt was made to logon, but the network logon service was not started. Are there any other things I could try? All help is more than appreciated!

• Force logoff of idle users on Windows 7 workstation with fast user switching enabled

  - by newmanth

  We have mission-critical Windows 7 workstations on our network that must be available to any user at any time, even when it has been locked by a prior user. Thus, we have fast user switching enabled. Unfortunately, it's not unusual for us to have a dozen or more different users logged onto the same machine at the same time, with a corresponding degradation in service. We've done our best at educating the masses to log off at the end of their shift. But users being users, this does not happen on a consistent basis. Does anyone know of a clean way to force logoff idle users after a certain amount of time has elapsed? I am open to any method that could be deployed/configured via script, GPO, or SCCM.

• Virtualizing Firewalls/UTM

  - by TheD

  So Sophos UTM (Astaro Gateway UTM) can be virtualized in Hyper-V, VMWare, vSphere etc. Now I'm new to virtualization, so am wondering how the networking would be configured in this situation. Imagine the following (a very simple setup). A Zyxel router acting as the default gateway, standard ADSL line. This is connected directly via Ethernet to my VHost, Hyper-V in my case. Now I assume I need two virtual network adapters, one which is the "External" interface to the firewall, and the other being the "Internal" interface. But where does my switch go, since I have 5 machines (or X number of machines). Where is the switch connected, to the internal interface on the VHost? What default gateway do my clients use etc? How would the routing work if these two interfaces weren't bridged since they are virtual networks anyway. I'm a little confused! Any advice is much appreciated! Cheers

• Install Windows XP/7 without a CD drive when the BIOS does not support booting from USB devices

  - by David Pearce

  I have a computer that has a dead CD drive in it and it seriously needs a new installation of Windows (XP is on it now, but Windows 7 does not sound that bad). At first I tried making a bootable USB drive, but it does not look like the BIOS supports booting directly from a USB drive. Is there some sort of boot loader that I can put onto the hard drive first and boot from the USB drive using that? If not, how else can I re-install Windows on the computer? Edit: The only bootable device the computer has it the network with PXE (although I have no idea how to do that) and it's three internal hard drives

• IIS site not resolved by DNS server

  I've a problem with my network. My Config: SVR01 (ws2008r2): DNS server and Domain Server SVR02 (ws2008r2): IIS (v7.5) Domain Clients In SVR02 there are many sites. When I try to connect on one site (such as: demo1.myhomesite.intra) the browser say "Internet Explor can not display the webpage". Well... In this case I found a workaround: unplug and plug the lan cable (or disable and enable wifi) in my client and the site work correctly. But this workaround is not a solution. Please, can you help me??

• Particle trajectory smoothing: where to do the simulation?

  - by nkint

  I have a particle system in which I have particles that are moving to a target and the new targets are received via network. The list of new target are some noisy coordinates of a moving target stored in the server that I want to smooth in the client. For doing the smoothing and the particle I wrote a simple particle engine with standard euler integration model. So, my pseudo code is something like that: # pseudo code class Particle: def update(): # do euler motion model integration: # if the distance to the target is more than a limit # add a new force to the accelleration # seeking the target, # and add the accelleration to velocity # and velocity to the position positionHistory.push_back(position); if history.length > historySize : history.pop_front() class ParticleEngine: particleById = dict() # an associative array # where the keys are the id # and particle istances are sotred as values # this method is called each time a new tcp packet is received and parsed def setNetTarget(int id, Vec2D new_target): particleById[id].setNewTarget(new_target) # this method is called each new frame def draw(): for p in particleById.values: p.update() beginVertex(LINE_STRIP) for v in p.positionHistory: vertex(v.x, v.y) endVertex() The new target that are arriving are noisy but setting some accelleration/velocity parameters let the particle to have a smoothed trajectories. But if a particle trajectory is a circle after a while the particle position converge to the center (a normal behaviour of euler integration model). So I decided to change the simulation and use some other interpolation (spline?) or smooth method (kalman filter?) between the targets. Something like: switch( INTERPOLATION_MODEL ): case EULER_MOTION: ... case HERMITE_INTERPOLATION: ... case SPLINE_INTERPOLATION: ... case KALMAN_FILTER_SMOOTHING: ... Now my question: where to write the motion simulation / trajectory interpolation? In the Particle? So I will have some Particle subclass like ParticleEuler, ParticleSpline, ParticleKalman, etc..? Or in the particle engine?

• How do I setup a local DNS server on Mac OS Lion?

  - by Peter Kovacs

  I had some serious lag to resolve website address and sometimes things simply wouldn't load (pages kept loading for 5+ minutes without even a timeout error). So I had setup a local dns server/cache using BIND on Leopard and Snow Leopard. Now that I have Lion, i have the same problem, but the instructions no longer apply to Lion and I can't find a way to do it. Has anyone attempted to do this? Are there viable alternatives for DNS servers on OS X 10.7? For those who are wondering I already tried several external DNS server. Only my computer has this issue on the network.
