• Xen and Ubuntu?

  - by wag2639

  How does one properly approach having Ubuntu servers on a Xen hypervisor? I don't have any experience with RAID or Xen other than from a theoretical level. Additional requirements: Use with mdadm Software RAID 5 (can be on separate disks) that multiple instances with access Paravirtualized Ubuntu Server guests instances Possible ideas for now: Ubuntu host (dom0) with ubuntu-xen-server package (this purportedly isn't supported) dom0 host will "own" RAID 5 partition More Ubuntu servers as guests Citrix XenServer bare-metal host XenServer will own RAID Citrix XenServer bare-metal host Ubuntu guest instance creates and owns RAID Questions and concerns: Can Ubuntu be used as a dom0 Xen host? Can XenServer install packages such as mdadm and create a partition? Can multiple guest access (R + W) to the same data partition (RAID)? Note: since it may have a bearing on support, I'm referring to Ubuntu Server 10.04

• Best Solution For My Requirements

  - by Eray

  Hello, I'm a web developer. I have a few small online web application and a few Wordpress blogs. But i don't have too much experience with installing / configuring web servers . One of my web application needs cron jobs. It will check a lot of web sites availability. And, this application will leech too much RAM. And i think shared-hosting isn't suitable for this. But 1GB storage is enough i think. I don't need too much storage for my web sites. What do you think ? Which hosting solution is more suitable for my requirements ? Reseller ? VPS ? Cloud Server ? etc ...

• Connect macbook to my LAN through a VPN - best solution?

  - by LewisMc

  So I have a LAN connected via a ADSL/PPPoA, this is using a bog-standard DLink router supplied by my ISP (talktalk UK). I have a NAS within the LAN that is running FreeNAS and I want to be able to connect to it when I'm out and about. It's running an atom so it's quite low on juice consumption but I don't want to have it on all day and night so I've been waking it via a magic packet and booting it down from the web admin when I need it. So I want to connect to the LAN, I presume via a VPN, to be able to send a magic packet. But what is the best method to accomplish this, or is there an easier way? I've been looking at the cisco 857 integrated router and the Netgear prosafe 318(behind modem) but not sure If I'm on the right track with what I want to achieve as I've not much experience or knowledge with VPN's or networking (software engineering student). I have tried port forwarding but to no avail, either with magic packets or even connecting outside the LAN via DYNDNS. Thanks,

• Best technique for reusing a Windows system image across configurations

  - by Martin Wiboe

  We are a small company that provides solutions for ventilation systems. Part of the solution is a "controller" which communicates with the ventilation equipment. These controllers are simply Dell computers that come with our Windows 7 system image on them and sometimes some special hardware. We typically do a batch of 10 controllers at a time. We have been using Norton Ghost to apply the system image, but this process breaks because Dell changes the system configuration often, and our Windows image now does not contain the correct drivers. This is especially a problem when they change the RAID controller. To improve this, I see 2 options: use some kind of virtualization and install a hypervisor on each PC. This would solve the driver problem, but probably cause trouble with our special hardware. use some method of adding the proper drivers to our Windows image in offline mode. I haven't got much experience in either of these approaches. How would you solve our problem?

• Port Redirection on Mac OS X Lion

  - by Andreas

  I have tried to solve this issue using pf but with no luck. Basically, I am trying to redirect incoming port 443 traffic to port 22. I have tried to set up a rule in a file and load it in pf but I get syntax error. Can anyone with more experience with pf provide some insight? Here's what I've attempted: pass in on en1 proto tcp from any to any port 443 rdr-to 127.0.0.1 port 22 and pass in quick proto tcp to port 443 rdr-to 127.0.0.1 port 22 I've been able to do this in MacOSX Snow Leopard with ipfw: sudo ipfw add 1443 forward 127.0.0.1,22 ip from any to any 443 in but it doesn't work in Lion (it gives me an Invalid Argument error).

• Fastest web server for serving static content

  - by Swader

  Hello, I'm optimizing our system for some faster static content delivery, and was wondering if anyone has any proper experience with the fastest web servers out there for such a purpose. From the three main candidates I've considered, Nginx, Cherokee and Lighttpd, each seems to have its own problems - but the reports I've read online are somewhat biased and lean towards whichever server the user is currently using. Any ideas on where to see a proper benchmark for this specific purpose, or at least a non-biased list of pros and cons? Any personal experiences and pitfalls I should be vary of? Thanks Edit: Serverfault.com gave the answer as nginx. I'd still like to hear some developer thoughts from this end of the universe.

• Nvidia 9 series or Intel HD 2000? [closed]

  - by EApubs

  I just tested an Nvidia 9300 GS card with a Intel Corei3 HD 2000 graphics system. Here is the windows experience index scores I got : Nvidia 9300 GS : Base Score 3.9 Processor : 7.1 Memory : 7.5 Graphics : 3.9 Gaming Graphics : 5.1 Hard Disk : 5.9 Intel HD 2000 : Base Score : 5.2 Processor : 7.1 Memory : 5.9 Graphics : 5.2 Gaming Graphics : 5.8 Hard Disk : 5.9 My questions are : When using Intel HD graphics, it reduces the score of my Ram! How is that possible? It checks the speed of the ram. Not the size (i think). Intel graphics take some of the ram space but how can that effect the speed? From both of them, what will be the good choice?

• Downloading content greater than 2000 bytes from local network hangs in browser on Windows XP

  - by artplastika

  We have web application that runs under Tomcat in a local network. Our customers experience strange problem using this web application. Let's say Tomcat server runs on host1 and we open webapp URL in browser on host2. Any browser on host 2 starts opening page and downloading of content "hangs" for hours. We've made bunch of experiments and found that any content larger than 2000 bytes makes browser request hang. Tried in Internet Explorer 8, Opera 12, Firefox. At the same time if user opens website from internet, it works. Opening webapp from the same host1 where Tomcat is running works normally. Local network is organized with D-Link DGS-3120-48TC switch. Additional info. During experiments we've noticed XP Tweaker installed on hosts. Network settings from that tool: MTU is manually set to 1500 RWIN = 14600 Support of TCP frames larger than 64 KB is on Time to Live = 32 SACK is on

• Terminal Server 2003 Performance Troubleshooting

  - by MikeM

  Let me get your thoughts on terminal server performance problems. The server hosts average 25 users which, after running some numbers, on average use 600MB memory with their main applications running (web browser, adobe reader, IP phone client). All users are on the same LAN as server. We constantly experience slow response and short session lockups. Combined CPU usage is on average 10%. What appears strange to me is that the system shows 29GB physical memory with 25GB of it free. The page file usage is about 50% averaging 9GB used. Some server specs OS: Server 2003 32bit Enterprise with /PAE flag RAM: 32GB CPU: 2xQuad Core @ 2.27Ghz HD: RAID5 1.2GB After doing basic troubleshooting using performance monitor it leads me to believe that the performance problems are caused by the 32bit OS limitation in addressing full 32GB of physical memory even though the /PAE flag is used. Can anyone suggest something, troubleshooting steps that can lead to a more conclusive answer? Thanks

• What are the minimum required modules to run WordPress

  - by Mister IT Guru

  Recently a 'consultant' came in to talk to bean counters at my place of employment, with regards to being more efficient with our IT infrastructure. They suggested to be more efficient we should only load the Apache modules that are required on our web servers. (This is just 1 of 1Ks of suggestions). The Bean Counters are very excited, and prepared for me to spend the time to investigate this avenue of cost cutting. I don't mind this mundane exercise, I see it as a learning experience! I guess this leads me to the actual question: How can I determine the minimum required apache modules for a PHP based application without actually going through the code, or plain old trial and error?

• how to stop a driver from running - it self protected and rootkit hidden

  - by Aristos

  I have this serous problem For the first time I can not stop a program from running. Something is on one laptop computer that is run as system legacy driver, and self protected and hidden on service as rootkit. Anything I try to remove fails. When a program or anti toolkit try to remove the hidden registry setting for make it stop I get this error : "a device attached to the system is not functioning" So any idea that can help me stop it from running, or even delete it on start up ? My one limitation is that the hard drive is on a laptop and I can not remove it and attact it to somewhere else. This program not let me, touch the registry, do not let me touch the file, do not let me touch the file, The move on boot fail to delete it, the rootrepeal fail to delete it, the rootkiet reveal from sysinternals fail to reveal it ! everything fails. Do how have any experience on this, or do you have any suggestion how to stop this driver from run ?

• Can qmail-ldap replace the validrcptto file?

  - by T. Fabre

  We are using qmail to route incoming mail to our Domino server. However, that requires us to maintain the validrcptto with the list of all allowed email addresses. Since Domino provides an LDAP directory, does qmail-ldap provide functionnality to lookup valid rcpt to addresses in the Domino directory instead of the validrcptto file, so that we wouldn't have to maintain that extra list ? We have about 150~200 users, so is setting up qmail-ldap worth the extra mile if it can verify addresses in the LDAP directory ? If anyone has experience with qmail-ldap and its setup, I'd be glad to hear from you.

• Missing Right Click Menu Text After Sleep

  - by petebob796

  I have a laptop running Windows 7 and regularly close the lid to put it in sleep mode. Recently after resuming from sleep if I go to access the right click menu in the windows shell when I hover over the menu items the text disappears and doesn't re-appear without closing the menu and right clicking again. The only way to fix this is to restart. Any ideas what could be causing this? I have an nvidia 8600m gs graphics card which had a BSOD problem a while back at boot up but since I underclocked it slightly it has been running fine and I experience no other issues but this. This only affects right click menus that are part of the windows so not any programs right click menu. It's not a major problem just strange and a little annoying.

• Asus WL-520GC + external HDD via Ethernet

  - by Azat

  Has anyone experience of using such combination? Exactly with the same model (or from same model line). How does it works? How hard is to set up all that? What difficulties? I use this router a couple of years, but now i haven't such external drive at my disposal. I want to buy something like Verbatim 47591 or Western Digital WDH1NC10000. (By the way, my router has no USB ports, therefore only Ethernet-ports for external HDD are supported.) Thanks you a lot in advance!

• Optimal dir strcuture for keeping millions of files on an ext4 system

  - by Alex Flo

  I need to keep millions of files on an ext4 system. I understand that having a structure with multiple subdirectories is the general accepted solution. I wonder what would be the optimal approach in terms of number of dirs/subdirs. For example I tried a structure like 16/16/16/16 (that is, (sub)directories from 1 to 16) and I found that I am able to move 100K files to this structure in 2m50s. When trying to move 100K files to a 8/8/8/8/8/8 structure it took 11 minutes. So the 16/16/16/16 approach seems to be better but I was wondering if anyone has some empirical experience with an even better dir/subdir distribution.

• How do I create a free server-side database to be accessed via Windows forms and/or browser?

  - by NoCatharsis

  I have no formal education in databasing or programming, but I've learned enough SQL, C++, and C# to at least get started setting up a small database on my company's server. Using MS SQL Server 2008 R2, I have created the database and set up columns with proper data types. However, there seems to be a lot of tweaks and details that are way over my head. Since I would like these data to be accessible to the other 7 or 8 people in my office (preferably via web browser), I'm wondering whether this is the best setup for my situation. The other option I've read about is a LAMPP server, which I assume is the competing free option to Microsoft's Express packages. I know nothing of LAMP servers except from the articles I've read on how to set them up (and I believe I even saw a detailed tutorial somewhere). To summarize, my question is this: Which of these (or any other) server setups would best suit my purposes, keeping in mind that I'm a true novice (but willing to learn), and would like to keep it free until I get more experience?

• How to get the pid of a running process using a single command that parse the output of ps?

  - by Sorin Sbarnea

  I am looking for a single line that does return the pid of a running process. Currently I have: ps -A -o pid,cmd|grep xxx|head -n 1 And this returns the fist pid, command. I need only the first number from the output and ignore the rest. I suppose sed or awk would help here but my experience with them is limited. Also, this has another problem, it will return the pid of grep if the xxx is not running. It's really important to have a single line, as I want to reuse the output for doing something else, like killing that process.

• LVM mirroring VS RAID1

  - by syrenity

  Hi. Having learned a bit about LVM mirroring, I thought about replacing the current RAID-1 scheme I'm using to gain some flexibility. Problem is that according to what I found on the Internet, LVM is: 1) Slower then RAID-1, at least in reading (as only single volume being used for reading). 2) Non-reliable on power interrupts, and requires disk cache disabling for prevention of data loss. http://www.joshbryan.com/blog/2008/01/02/lvm2-mirrors-vs-md-raid-1/ Also it seems, at least to several setup guides I read (http://www.tcpdump.com/kb/os/linux/lvm-mirroring/intro.html), that one actually requires a 3rd disk for storing the LVM log. This makes the setup completely unusable on 2 disks installations, and lowers the amount of used mirror disks on higher amount of disks. Can anyone comment the above facts, and let me know his experience of using LVM mirroring? Thanks.

• Test-service on Internet for testing incoming INVITE

  - by leiflundgren

  I am trying to set up Asterisk at home. I think I'm having trouble configuring my firewall, so that inbound traffic is accepted, but I am not sure. I got the idea that, perhaps, there is a service out on the Internet, where I can, though a web-browser, initiate an incoming call, an INVITE. And then see the SIP-trace that the remote-part experience. Anyone know of such a service? Note. I have a SIP-PSTN provider so I can generate inbound calls. But I cannot see the SIP-logs from my provider...

• Installing GPSBabel on CentOS 5 x86_64

  - by Clint Chaney

  Well first let me say I have no clue about doing anything on my server, I ask my host to do all installs for me. I run a website where users store latitude and longitude coordinates in my database. I would like them to be able to download these waypoints to their gps units. I found a program called GPSBabel that allows this to be done. http://www.gpsbabel.org/ I want to be able to control GPSBabel from PHP using exec() or something along those lines. The problem is that the linux version of the program is a source file and they don't want to build or install it without some source of instructions. Does anyone have experience with installing this? Perhaps know someone that has and that can lead me in the right direction? Any help would be hugely appreciated. I'm pretty much stuck without getting this to work.

• How can I share files from my Windows 7 machine to my friend's Ubuntu machine?

  - by ProfKaos

  I run a Windows 7 Pro SP1 laptop as my home machine, and my housemate runs an Ubuntu 12.04.1.05 desktop. We share a WLAN. I would like to make certain locations and files available for him to read and maybe write. How can I go about this? Bearing in mind I have very little recent experience with modern Linux, and Ubuntu in particular. My first idea is to share a Windows folder with my Ubuntu VM under VMWare Player, then his Ubuntu machine can connect to my Unbuntu VM, and the two can use whatever magic Ubuntu uses to achieve file sharing. This requires my Ubuntu VM to be always running though, and that may not always be possible. I have also heard that Samba may have a feature to help here, but I know nothing about that. How can I share my Windows files with my mate's Ubuntu machine, preferably with a 1 to 1 connection, i.e. rather not using shim VM's

• Do you find using a VPS worthwhile?

  - by Grant Palin

  I am currently on shared hosting, and have been recently looking at the idea of switching to a VPS instead. From what I have gathered, a VPS allows you more control over your server setup. But at the same time you have to set it up yourself, and maintain it. This is the bit I am asking about... Despite the power and flexibility you get from using a VPS, you have to take care of it yourself. Is it worth it? Some context: I am primarily a Windows user, but have been tinkering with various Linux distros off and on for several years. I know enough about Linux to get by, or to be dangerous - take your pick. I've also done some tinkering on my current host, but have no serious sysadmin experience. There's always a first time!

• Does SMTP greylisting a) stop much spam and b) stop much legitimate mail?

  - by Whisk

  I've just set up an SMTP server on a relatively little used domain using Postfix and enabled greylisting with SQLGrey. So far it seems to be working OK, and while there's the slight irritation of delays to emails from new senders, I can see from the logs that it's deterring a number of spam messages. In your experience does greylisting effectively stop much spam? Is it a useful addition to e.g. SpamAssassin or is adding it on top overkill/unnecessary? If I were to roll this out to heavier use domains (perhaps with more demanding users) would you anticipate a significant portion of poorly configured mail servers that would end up bouncing or losing messages?

  I've recently installed SSMA on my computer and after connecting to both the Oracle instance (which holds the database to be converted) and the SQL Server. I've mapped the needed schemas from oracle to mssql. The problem is that when i click on the report button for the assessment report there's an error popping up: Assesment Error : Nothing to Process The output window states: Starting conversion... Analyzing metadata... Conversion finished with 0 errors, 0 warnings, and 0 informational messages. There is nothing to process. Has anyone got experience with SSMA. I can't figure out what I am doing wrong. Thank you.

• SAS instead of SATA 2 for my hard drives?

  - by jasondavis

  I am building a new system soon, I will have multiple 1-2tb hard drives for storage in it. I only have experience uasing the sataII drives but I saw somewhere that I should be using something like SAS? I read that if I were going to have 20 drives that I could use 4 SAS cables vs 20 SATA cables. Can someone help me understand this better? If it were only 4 cables then how would 20 drives hook up? Also can a regualr sata2 drive hook up to that?
