• Aging SBS needs updates / Thoughts for one-off, off-line complete backup?

  - by tcv

  Hey guys, So, we checked out the status of an SBS 2003 at one of our more recent, spend-averse clients and found it to be woefully out-of-date. Scary out of date. I think it's running IE2. Ok, maybe not that far back. Anyway, I was thinking that I could use some kind of disk-imaging software to image the four IDE drives within and, in the event the server gets some kind of Update Induced Indigestion, I could completely restore. Usually my go-to software for this is Acronis, but my client will likely balk at a $500 price tag for a one-off backup with their server product. I had thought we could use the boot media from, say, Backup & Recovery 10 to take an off-line image of all the drives. According to their CHAT tech support, however, it will not work. I pressed for the technical reasons and they said they'd email me. They haven't emailed me. They still might. This server is running SBS 2003, pre sp2. It's got four IDE disks. One is a Basic disk, which contains the O/S. The others are bound as a dynamic disk. You might ask: "Don't they already have backup software?" They do! Backup Exec, a very low-end version that won't even do VSS. I don't know much about BE, but it seems to me that if the worst were to happen, it would mean building a new server O/S, installing BE (if the media is available), then restoring. Would it even work? I can take the system down for hours to do a backup and my goal here is a pretty dead-simple restore if the worst happens. Any and all suggestions are exciting. m

• EC2 kernel decision and issues with creating a new machine with my AMI

  - by roacha

  I could really use some advice. I started a new instance on EC2 using Amazon's AMI and during the deployment process I selected a Kernel ID of "Use Default". I then configured my server the way that I wanted to and took a snapshot of it. I then created my own AMI to create new servers with. When I try and create a new server with this AMI the server fails to start and I get the error: EXT3-fs: sda1: couldn't mount because of unsupported optional features (240). Which appears to happen because I am selecting a kernel id of "Use default" again when building my second server. I have read that in order for this to work I need to choose the same kernel id that was used in my original server. I have deleted my original server and don't know what it was using. What is the best process to follow in order to not have these issues? Should I choose "Use Default" for my original server? How do you know which kernel it selected? Then should I just document this and always specify this during the deployment of my next servers using my custom AMI? OR should I choose a custom kernel id during the initial build and always use this one moving ahead hoping Amazon never retires it? Thanks for any advice!

• Is there a limit to how many sites can be hosted on a single IP address when using HTTP Host Headers on Windows 2008?

  - by Kev

  For reasons that are lost in the mists of time, our older Windows (2000, 2003) servers have been configured with a "Administrative" IP address and three further "Hosting" IP addresses. There are also additional IP's for sites with SSL certificates. The "Administrative" IP address is where all our internal provisioning, monitoring and other such apps are bound to. We lock this down and don't permit access to it from the outside world (other than over our VPN). The three "Hosting" IP addresses are used for IIS website hosting (in conjunction with host headers). Historically, new site IP address allocations have been rotated through these three IP addresses. I'm not really sure why. I'm building a new batch of servers and I'm considering just having a single hosting IP address. Our servers can host up to 1200 sites on a single machine. Is there a technical limit to the number of IIS sites that can bind to a single IP address? Our Linux platform seems to do just fine with just a single shared IP + host headers. I initially thought this might be an SEO thing, but given that IPv4 address space conservation is paramount I hardly think Google or other search engines could reasonably penalise site rankings just because hundreds of sites hang off the same IP.

• Thunderbird 11.0.1 and Lightning 1.3: How do I propose a different time for a meeting?

  - by seaao

  This all happens on my x64 Linux workstation btw. tl;dr: My colleague invited some people and me for a meeting. The meeting was scheduled a week to late. I -wrongfully- accepted. How do I propose a new time? To explain a bit more in detail: I received a meeting request in my mailbox. Thunderbird is so nice to let me accept or reject it, and after I click the button to accept, it is directly added to my calendar. But when I double click on the meeting to edit it, I get a function-wise scaled-down version of the meeting: The only settings I can alter are whether I want reminders, and if I go at all. Trying to drag it to another day doesn't work either: My calendar behaves like read-only (which it isn't btw). There are several questions (without answer...) to be found on Stack Overflow and on the Thunderbird knowledge base about using lightning. But I get the idea that I'm one of the few who won't comply with the team even before the meeting is started. My googling revealed no bugs or feature requests in the direction I'm thinking. A link to an explanation how to achieve this, or another perspective about how to reach the desired goal (meeting with my colleagues and me) would be mostly welcome!

• How do you link a time stamp to a cell using a userform button control? [migrated]

  - by Chad Cochrane

  Hello fellow VB Developers/Users/Hobbyists/What-Have-You! I have a user form that has two buttons: 1. Start 2. Stop When I press start, I would like it to record the current time with this format: (dd/mm/yy hh:nn:ss:) in a specific column. Then when I press the Stop Button I would like it to record the time again in the cell next to it. Then if I press start Again I would like it to record below the first cells current record. Basically I am building a timer to record data to see how long certain tasks take. I will post the excel file and provide more information were necessary. Thanks for any help provided. CURRENT CODE Public runTimer As Double Public startTime As Date Dim counter As Date Sub setStart() counter = 0 startTime = Now runTimer = Now + TimeSerial(0, 0, 1) Application.OnTime runTimer, "setStart", , True Set myTime = Sheet4.Range("F1") Set timeRng = Sheet4.Range("C8:C100") i = WorksheetFunction.CountA(timeRng) i = i + 1 Cells(i, "C") = myTime Sheet4.Cells(i, "C").NumberFormat = "yyyy/mm/dd HH:mm:ss" If i >= 2 Then Cells(i, "D8") = Cells(i, "C8") - Cells(i - 1, "C8") Sheet4.Cells(i, "C").NumberFormat = "yyyy/mm/dd HH:mm:ss" End If Application.EnableEvents = False End Sub Sub setStop() Application.OnTime runTimer, "setStop", , True Set myTime = Sheet4.Range("F1") Set timeRng = Sheet4.Range("D8:D100") i = WorksheetFunction.CountA(timeRng) i = i + 1 Application.EnableEvents = False Cells(i, "D") = myTime Sheet4.Cells(i, "D").NumberFormat = "yyyy/mm/dd HH:mm:ss" End Sub

• Simple, centralized user management on a small LAN - NIS or LDAP?

  - by einpoklum

  I'm setting up a small LAN for my team. It will, for all intents and purposes, not be connected to any external networks. I would it to have centralized control of user accounts (at least, I think I'd like that; I'm also considering using puppet, so theoretically I could just push /etc/passwd changes, or something). The number of machines is fixed, but not very small. Mostly they're 'attached' to a single user, but sometimes people work remotely on someone else's box; and there are a couple of servers. I've read this question, but my scenario is much simpler (even simpler than in this question) and I'd like to do something (relatively) quick, with not much hassle, but not a dirty totally-insecure hack. Is NIS relevant for my scenario? If not, what's the most hassle-free way to set up LDAP (or LDAP+Kerberos) to achieve the same? Notes: I have no experience with setting up either NIS or LDAP. We use Debian-flavored Linux distributions, mainly Kubuntu 12.04 (not my choice, but that's the way it is).

• Automatically update SVN repository on another server

  - by Mikey C

  We have 2 Ubuntu web servers, one of which is our staging server (Staging) and the other is our live server (Live). Staging has our Subversion repository, as well as the latest version of our sites on it. Because the SVN server is running on Staging, I've added post-commit hook scripts so that the staging server automatically has the latest code. Easy. However, I'd like one of the repositories on Live to also stay updated. This is a repository of images, PDFs and suchlike. When a team member commits to this, I'd like it to automatically update on the live servers so it can be used in mailings, content managed pages etc. I'd add something to the post-commit to SSH across and update, but for security, we can only SSH from one server to another as user 'commandLine', whereas the 'www-data' user runs the post-commit. I'd rather not run a cron on Live to update every 5 minutes, but I can't see another way of doing it without altering all our user permissions. Any ideas?

• What's the mysql-5.5 compilation configuration arguments on Ubuntu 10.04?

  - by photon

  I want to install mysql 5.5 on my Ubuntu10.04 desktop system. But I'm not sure what arguments I should use after the cmake command. Though I've seen these articles: https://wikis.oracle.com/display/mysql/Cmake Building mysql-5.5.19 from source on ubuntu 11.10 with the static flag Compile MySQL 5.5.15 from source using autorun.sh and cmake, unable to start MySQL after Would anyone like to share the mysql-5.5 configuration arguments of compilation on Ubuntu 10.04? $cmake # what arguments to enter for this command update: cmake . -DBUILD_CONFIG=mysql_release -DCMAKE_INSTALL_PREFIX=/path/to/mysql_installation_dir -DWITH_SSL=no the official web site says it need to use cmake to compile the source package, but according to a teck blog, it doesn't need to compile the source, so which one is correct? When I use Cmake, I also had following error message: $ sudo cmake . -DBUILD_CONFIG=mysql_release -DCMAKE_INSTALL_PREFIX=/usr/local/mysql_community_5.5 -- The CXX compiler identification is unknown CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.

• openvpn in a bridge?

  - by sebelk

  I have a somewhat tricky proble to solve. We have a wireless link between 2 building. One of them has an mikrotik and below there are some vlans. Some machines of one vlan need to use openvpn to connect to a remote private lan. I put a TP-Link WR1043ND (which those machines connect to) with openwrt with ebtables just in case I need it. I've configured openwrt in such a way that all ports belongs to the same vlan. My idea was to make things as transparent as I can. It has a bridge as follows: usr/sbin/brctl-full show br-lan bridge name bridge id STP enabled interfaces br-lan 8000.f8d111565716 no eth0.1 eth0.2 Also I've added an ebtables rule: ebtables -t broute -A BROUTING -p ipv4 -j DROP So "bridge" has only one IP address. I've installed openvpn and I'm trying to bring up the tunnel but I can't still get working. Sure, someone can says why don't you use the vpn on the mikrotik, there are some reasons, the first one is I have little experience with mikrotik and I'd want to have the vpn at hand :) The problem is that openvpn is not working, because it is complaining that I have only one Ip Address on the server side. So I set up and alias interface with another IP address but is not working either: : Rejected connection attempt from IP-Client-Side:37801 due to --remote setting Is there a way to make it work?

• Linux iptables / conntrack performance issue

  - by tim

  I have a test-setup in the lab with 4 machines: 2 old P4 machines (t1, t2) 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t3) Intel e1000 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t4) Intel e1000 to test linux firewall performance since we got bitten by a number of syn-flood attacks in the last months. All machines run Ubuntu 12.04 64bit. t1, t2, t3 are interconnected through an 1GB/s switch, t4 is connected to t3 via an extra interface. So t3 simulates the firewall, t4 is the target, t1,t2 play the attackers generating a packetstorm thorugh (192.168.4.199 is t4): hping3 -I eth1 --rand-source --syn --flood 192.168.4.199 -p 80 t4 drops all incoming packets to avoid confusion with gateways, performance issues of t4 etc. I watch the packet stats in iptraf. I have configured the firewall (t3) as follows: stock 3.2.0-31-generic #50-Ubuntu SMP kernel rhash_entries=33554432 as kernel parameter sysctl as follows: net.ipv4.ip_forward = 1 net.ipv4.route.gc_elasticity = 2 net.ipv4.route.gc_timeout = 1 net.ipv4.route.gc_interval = 5 net.ipv4.route.gc_min_interval_ms = 500 net.ipv4.route.gc_thresh = 2000000 net.ipv4.route.max_size = 20000000 (I have tweaked a lot to keep t3 running when t1+t2 are sending as many packets as possible). The result of this efforts are somewhat odd: t1+t2 manage to send each about 200k packets/s. t4 in the best case sees aroung 200k in total so half of the packets are lost. t3 is nearly unusable on console though packets are flowing through it (high numbers of soft-irqs) the route cache garbage collector is no way near to being predictable and in the default setting overwhelmed by very few packets/s (<50k packets/s) activating stateful iptables rules makes the packet rate arriving on t4 drop to around 100k packets/s, efectively losing more than 75% of the packets And this - here is my main concern - with two old P4 machines sending as many packets as they can - which means nearly everyone on the net should be capable of this. So here goes my question: Did I overlook some importand point in the config or in my test setup? Are there any alternatives for building firewall system especially on smp systems?

• Serving images from another hostname vs Apache overload for the rewrites

  - by luison

  We are trying to improve further the speed of some sites with older HTML in order as well to obtain better SEO results. We have now applied some minify measures, combined html, css etc. We use a small virtualized infrastructure and we've always wanted to use a light + standar http server configuration so the first one can serve images and static contents vs the other one php, rewrites, etc. We can easily do that now with a VM using the same files and conf of vhosts (bind mounts) on apache but with hardly any modules loaded. This means the light httpd will have smaller fingerprint that would allow us to serve more and quicker, have more minSpareServer running, etc. So, as browsers benefit from loading static content from different hostnames as well, we've thought about building a rewrite rule on our main server (main.com) to "redirect" all images and css *.jpg, *.gif, *.css etc to the same at say cdn.main.com thus the browser being able to have more connections. The question is, assuming we have a very complex rewrite ruleset already (we manually manipulate many old URLs for SEO) will it be worth? I mean will the additional load of main's apache to have to redirect main.com/image.jpg (I understand we'll have to do a 301) to cdn.main.com/image.jpg + then cdn.main.com having to serve it, be larger than the gain we would be archiving on the browser? Could the excess of 301s of all images on a page be penalized by google? How do large companies work this out, does the original code already include images linked from the cdn with absolute paths?

• Convert MPG w/ AC3 audio to something else - on a Mac

  - by anonymous coward

  I'm helping with a small volunteer media team, and they have several .mpg videos that don't appear to have sound when played in QuickTime, iTunes, Real Player, etc, on the local Mac machine. I was able to hear audio after transferring one of the movies to a Windows machine that had VLC media player on it. Through VLC I was able to discover that the audio stream is a52 / AC3 format. We use Autodesk Cleaner in our normal workflow of converting the format of our videos to FLV, but for some reason it's unable to convert this particular batch of videos (well, the video converts fine, but with no audio). Obviously, it seems that there's a codec issue here, but I'm not sure how to correct it. (I'm not extremely familiar with Macs, and/or Autodesk Cleaner). I've seen the Perian codec pack, but I'm not sure that having the codecs on the system will enable Cleaner to convert these videos (particularly the audio stream, since the video converts fine). Is there something obvious that I'm overlooking, or will we have to use something else for this particular batch of videos? If so, what?

• Why does Google Analytics use two domains?

  - by AKeller

  I'm building a distributed widget that is comparable to Google Analytics. Users will add a <script> tag to their site that references my widget's JavaScript file. The Google Analytics tracking code looks like this: var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-XXXXXXXX-X']); _gaq.push(['_trackPageview']); (function () { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); Can anyone explain the reasoning behind separate HTTP and HTTPS hostnames? My instinct is to just secure the www address and then use the protocol-less syntax, like //www.google-analytics.com/ga.js. But I'm sure the Google Analytics architects put a lot of thought into this approach. I'd love to understand their logic before I follow/ignore their model.

• windows: force user to use specific network adapter

  - by Chad

  I'm looking for a configuration/hack to force a particular application or all traffic from a particular user to use a specific NIC. I have an legacy client/server app that has a "security feature" that limits connections based on IP address. I'm trying to find a way to migrate this app to a terminal server environment. The simple solution is for the development team to update the code in the application, however in this case that's not an option. I was thinking I might be able to install VMware NIC's installed for each user on the terminal server and do some type of scripting to force that user account to use a specific NIC. Anybody have any ideas on this? EDIT 1: I think I have a hack to work around my specific problem, however I'd love to hear of a more elegant solution. I got lucky in that the software reads the server IP address out of a config file. So I'm going to have to make a config file for each user and make a customer programs files for each user. Then add a VMware NIC for each user and make each server IP address reside on a different subnet. That will force the traffic for a particular user to a particular IP address, however its really messy and all the VM NIC's will slow down the terminal server. I'll setup a proof of concept Monday and let the group know how it affects performance.

• Problem with setting up RAID 5 on FreeNAS

  - by Benjy23

  I've been running FreeNAS for a while now. Hardware is 1.8 GHz Celeron, RAM 1 GB. SATA card is Via - I am not sure about the model. It's 2 ports and I have 6 x 1.5 TB hard drives. All ran OK while running on 1.5 TB, no RAID. I'm now trying to create a RAID 5 with my 6 hard drives. Software RAID. Is it normal for it to take roughly up to 2 weeks just to build the RAID? Sorry, I'm very new to implementing RAID and googling doesn't tell much other than it takes a long time. Also the RAID building process seems to fail many times. Going to degraded. I suspect it's because 4 of my hard drives are connected to my motherboard and the other 2 are connected to my SATA card. What's your take? I'm considering 2 options now. Either get a 8 port SATA card and attach all the hard drives to it. Or get a RAID controller 8 portcard which is probably going to be more pricey. Also how do you access hardware RAID through FreeNAS? I like how FreeNAS emails you should your harddrive fails. Can this be done as well with hardware RAID?

• Hard drive causing BSOD

  - by JoshIrving

  I've come across a problem after building my new PC and installing a clean Windows 7. I originally planed on a RAID 1 or 0 but after further research I decided against it. So I was left with two 1TB Western Digital Black SATA 6Gb/s hard drives. My plan now was to use my second hard drive as a backup (using Windows Backup or 3rd party software). I set both hard drives to AHCI in the BIOS and installed Windows 7. I went through the lengthy process of downloading and installing each driver manually (latest versions), using the motherboard disk for a list of what I need. After a few restarts and before installing any software, I took an image backup onto DVD and the second hard drive. First witnessed the problem during the first scheduled Windows backup. The progress bar froze at about 70% (doc backup done, image backup in progress). It stayed still for 2 hours until it blue screened. Next time the backup froze, I tried shutting down. It logged me out and got stuck at the last step ("Shutting down" and blue spinner) for an hour, until I hard shutdown. I later realised this hasn't got anything to do with the backup. I ended up blue screening on almost every shut down (same place). Turns out, it's because of the second hard drive spinning down or turning off. The computer will now shutdown properly, as long as I remember to read or write to the second drive before executing shutdown. I've now set "Turn off hard disk after: Never" - No problems, so far. Do I have dodgy hard drive(s) or should I investigate the POWER_STATE_DRIVER_FAILURE BSOD - can it be a driver issue? AHCI?

• Linux Distro - GUI similar to Windows

  - by DeaconDesperado

  I am in the process of refurbing several older laptop machines for use by a couple college guys we have in training to learn basic web development in python. These are students who intern at my company and are hoping to do some work when the summer comes building simple client-oriented webapps (learning the basics of OOP, MVC webapp design in flask, etc.). We're trying to function as the "practical" side of their education. I would like to get them set up on these machines we have sitting about, but I'd like to use a linux distro that would have a gui that closely approximates what they are being compelled to use at school (windows.) I don't really have much of a preference as far as GUI goes since much of what we'll be learning together is accomplished on the command line. I just see this as an easier adjustment for them while they are still reliant on a graphical environment. In the past I'd go straight for Ubuntu, but since they started using the Unity GUI the responsiveness overall can be pretty clunky on older machines, especially since these machines (there are four of them) run the gambit on specs (though all are at least 1.0Ghz and none have anything better than basic integrated video.) Has anyone had to setup a similar working environment in Mint, bare Debian or Zorin? Thanks.

• How to add a writable folder to the PHP document root on linux

  We are building an example bash script for our PHP TestCoverage Tool use on Linux. The development environment is Ubuntu 12.04_1 but we intend to have the linux example work across as many linux versions as possible without modification. The example linux script requires a variable be set to the PHP Document Root path and by default uses a small PHP example source to show the user how our GUI and text report shows the covered and uncovered PHP code areas. The linux script is also intended to be easily alterable by the user to automate the TestCoverage display of users PHP code. The problem we are having with Ubuntu 12.04 (any linux?) is that the PHP Apache2 document root is defined in /etc/apache2/sites-available/default as /var/www and /var/www is defaulted with "drwxr-xr-x" read only access. So in order to add our own folder as /var/www/SDTestCoverage we must change /var/www to "drwxrwxrwx" read-write access. So it seems our script (at least on Ubuntu) will need to ... 1. acquire and save the /var/www permissions then do .. 2. sudo chmod 777 /var/www (to make writable) 3. mkdir -p /var/www/SDTestCoverage (create our folder under the document root) 4. sudo chmod 777 /var/www/SDTestCoverage (make our subfolder writable) 5. and finally restore /var/www permissions Thanks and our Questions are .. 1. Is this the standard way (using Ubuntu) one adds a writable folder under the PHP Document Root? 2. Is this the most general purpose way one adds a writable folder under the PHP Document Root on other versions of Linux?

• Relevance and Necessity of SNMP

  - by Adam Tannon

  Edit: I am in the process of designing a Java-based monitoring tool that will send back periodic "health checks" of a Java app deployed to a cluster of GlassFish servers. I am trying to figure out the best protocol for this monitoring tool to send information back to the monitoring server on. After an initial research effort on my part, it seems like SNMP is just a protocol for monitor-type applications to communicate the "health status" of something (a part of a network, a server, a cluster, an application, etc.) to the rest of the network. If the above is incorrect, please correct me!!! Assuming the generalization is more or less accurate, my next question is: why is this a protocol!?!? In the age of REST/SOAP/TCP protocols, why is there the need for a standardized protocol that only fits one type of application (monitoring)? In other words, if I'm a developer assigned to building a new monitoring tool that periodically polls a server and reports on its CPU and available memory, what advantages does SNMP give me over just POSTing to a RESTful API via plain 'ole HTTP? I'm sure I'm missing something here - I just need someone to help connect the dots! Thanks in advance!

• How can I optimize my ajax calls to deliver at 60ms.

  - by Quintin Par

  I am building an autocomplete functionality for my site and the Google instant results are my benchmark. When I look at Google, the 50-60 ms response time baffle me. They look insane. In comparison here’s how mine looks like. To give you an idea my results are cached on the load balancer and served from a machine that has httpd slowstart and initcwnd fixed. My site is also behind cloudflare From a server side perspective I don’t think I can do anything more. Can someone help me take this 500 ms response time to 60ms? What more should I be doing to achieve Google level performance? Edit: People, you seemed to be angry that I did a comparison to Google and the question is very generic. Sorry about that. To rephrase: How can I bring down response time from 500 ms to 60 ms provided my server response time is just a fraction of ms. Assume the results are served from Nginx - Varnish with a cache hit. Here are some answers I would like to answer myself assume the response sizes remained more or less the same. Ensure results are http compressed Ensure SPDY if you are on https Ensure you have initcwnd set to 10 and disable slow start on linux machines. Etc. I don’t think I’ll end up with 60 ms at Google level but your collective expertise can help easily shave off a 100 ms and that’s a big win.

• Slower/cached Linux file system required

  - by Chopper3

  I know it sounds odd but I need a slower or cached filesystem. I have a lot of firewalls that are syslog'ing their data to a pair of Linux VMs which write these files to their 'local' (actually FC SAN attached) ext3-formatted disks and also forward the messages to our Splunk servers. The problem is that the syslog server is writing these syslog messages as hundreds, sometimes thousands, of tiny ~4k writes per second back to our FC SAN - which can handle this workload right now but our FW traffic's going to be growing by at least a factor of 5000% (really) in coming months and that'll be a pain for the SAN, I want to fix the root cause before it's a problem. So I need some help figuring out a way of getting these writes cached or held-off in some way from the 'physical' disks so that the VMs fire off larger, but less frequent, writes - there's no way of avoiding these writes but there's no need for it to do so many tiny ones. I've looked at the various ext3 options, setting noatime and nodiratime but that's not made much of a dent in the problem. Obviously I'm investigating other file systems but thought I'd throw this out in case others have the same problem in the future. Oh and I can't just forward these messages to Splunk, our firewall team insist they're in their original format for diag purposes.

• What hardware would I need (approx) to run ESXi server?

  - by mr.b

  Hi, I am considering to purchase off-the-shelf commodity hardware in order to build server that will host virtual machines using ESXi server. Intended purpose for this server is NOT mission critical tasks. It will have to run perhaps 20-50 Windows XP/Vista/7 virtual machines (in total, but closer to 20 figure). Each guest would have to have 1-2 GB of ram, and probably two-three times more disk space than guest OS needs with clean install and all updates applied (that would be around 6-8 GB for XP, and i believe closer to 10-15 for win7). Those guests will act as a test ground for a new product that is network management software, thus guests will idle most of their time once initially loaded, but if I give them some task to complete, they should be able to perform reasonably well. Now, from what I have learned... CPU is usually not much of an issue (6 cores would do it), memory should not be lacking, but doesn't have to be sum of all guests, because of overcommitment... That leads me to IO, which is, as it seems, the bottleneck. Since I have very little experience with ESXi (and ESX, too) server, I'd like to ask: How much memory could I save by overcommitment, and how does it affect performance? Is 6-core cpu enough to run above described system? Would it be possible to run entire server off two (or even one) SSD drives (to host system virtual disks, with few additional HDDs (2-3) in RAID 0 to be used as secondary storage? I read somewhere that ESXi allows having something like "master image", essentially virtual machine that is "deployed" many times, so that disk space can be saved by having only differences stored by specific guests, instead of copying around whole virtual disks. Is this true, and how can this help me? Are there any other things I need to take into consideration when building this off-the-shelf solution? I should probably mention here that I'm fully aware of issues like SPOF regarding power supply, raid 0, etc, but since it's only a testing ground and not a production system, it's not so important for me. Thanks, B.

• Configuring PAM with pam_mount; getting a dlopen() with an HX_Init error

  - by Jamie

  I'm trying to get automounting upon login working on Ubuntu 10.03 Beta 2. I didn't find a package for pam_mount, so I ended downloading it and building it. This required: sudo apt-get install build-essential pkg-config libxml2-dev libssl-dev libpam-dev Additionally, the libHX-dev is required but as of yesterday (23/4/2010) the package version provided (3.2) wasn't up to snuff (3.4) so I downloaded, compiled and installed that too. cd ./pam_mount-1.36/ && ./configure && make && sudo make install When I tried it (pam_mount) I got this in my auth log: Apr 23 12:18:02 ubuntu sshd[1195]: PAM unable to dlopen(/lib/security/pam_mount.so): /lib/security/pam_mount.so: undefined symbol: HX_init Apr 23 12:18:02 ubuntu sshd[1195]: PAM adding faulty module: /lib/security/pam_mount.so Apr 23 12:18:06 ubuntu sshd[1195]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.20.182 user=jrisk Apr 23 12:18:06 ubuntu sshd[1195]: pam_winbind(sshd:auth): getting password (0x00000388) Apr 23 12:18:06 ubuntu sshd[1195]: pam_winbind(sshd:auth): pam_get_item returned a password Apr 23 12:18:06 ubuntu sshd[1195]: pam_winbind(sshd:auth): user 'jrisk' granted access Apr 23 12:18:06 ubuntu sshd[1195]: Accepted password for jrisk from 192.168.20.182 port 4369 ssh2 Apr 23 12:18:06 ubuntu sshd[1195]: pam_unix(sshd:session): session opened for user jrisk by (uid=0) What do I need to do get HX_Init into the system? This is related to an answer I previously got here.
