• Computer does not boot after ram upgrade

  - by Calmarius

  I have a Dell Optiplex GX520 desktop (it's abount 5 yr old) PC with 512 MB DDR2 RAM. Since my computer always swapping I thought I should upgrade my RAM. I bought a Kingmax 2GB DDR2 RAM. But my system does not boot. The status leds are on 2 and 4. The user manual says 'video card failure' wtf? I put back the original module and everything works. I tried many combinations. When I leave the old 512 RAM in and put the 2GB next to it to the other socket my system completes the POST and I'm able to enter the BIOS menu. It says my system has 2.5 GB installed, one 0.5GB and one 2GB in dual asymmetric channel mode. It's seemingly right. Exiting the BIOS setup GRUB loads successfully, but when I try to boot Ubuntu it crashes with kernel panic immediately. Trying to load Windows XP does not get past the loading screen, it crashes with 0x8E stop error. Does this mean the ram I bought is faulty? Or is it just mean that the memory module I bought is too new to be handled my computer? I this case I may exchange the RAM with my friends. No other computer is in my house (my very old box has DDR1 ram, my systers new box has DDR3 ones. I can't plug my memory in neither one.) I'm going to return the RAM to store to replace it with a better one tomorrow. Is there any hope to get this new module work?

• Problem in accessing Windows shared folder on Ubuntu using terminal

  - by vikramtheone

  Hi Guys, Description I have 2 systems with me, one running on Windows(Host) and one on Ubuntu, both on a LAN. On the Windows(Host) I develop software intended for the Linux system and because the Linux system has little external memory, my idea to overcome this is by making the project folder on the Host side a Shared Folder with full access and access it on Ubuntu over the network. To achieve this, I have installed Samba on Ubuntu, when I go to Places -> Network I can see the shared project folder and I simply mount it. A link appears on the desktop. Next, using Nautilus I open the link and I can access the contents of the shared folder. Problem Even though I mount the shared project folder, I don't see it appearing in the /media or the /mnt folder, as a result of this I don't know what path to use to access this folder, from the terminal. For example: When, I mounted my USB stick, as expected, a link for the device appears on the Desktop and I also see a folder in the media folder. So, similarly, a mounted shared folder should have appeared on the /mnt folder, too. Can anyone suggest what I should do now? There are many posts around, but no solid solution for this problem. Help!!! :) Vikram

• Why Wireshark does not recognize this HTTP response?

  - by Alois Mahdal

  I have a trivial CGI script that outputs simple text content. It's written in Perl and using CGI module and it specifies only the most basic headers: print $q->header( -type => 'text/plain', -Content_length => $length, ); print $stuff; There's no apparent issue with functionality, but I'm confused about the fact that Wireshark does not recognize the HTTP response as HTTP--it's marked as TCP. Here is request and response: GET /cgi-bin/memfile/memfile.pl?mbytes=1 HTTP/1.1 Host: 10.6.130.38 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:11.0) Gecko/20100101 Firefox/11.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: cs,en-us;q=0.7,en;q=0.3 Accept-Encoding: gzip, deflate Connection: keep-alive HTTP/1.1 200 OK Date: Thu, 05 Apr 2012 18:52:23 GMT Server: Apache/2.2.15 (Win32) mod_ssl/2.2.15 OpenSSL/0.9.8m Content-length: 1048616 Keep-Alive: timeout=5, max=100 Connection: Keep-Alive Content-Type: text/plain; charset=ISO-8859-1 XXXXXXXX...

Can somebody explain why Wireshark does not recognize it? Is there something wrong with the response?

• Apache httpd processes and PHP out of memory

  - by Ofri

  I have a VPS running apache-php-mysql on centos and a single drupal website installed. The VPS has 256MB of RAM (could be the root cause of all my problems... maybe I just need more). Whenever I try to open my website from multiple browser tabs (about 8... not 800) all at once, apache crashes! I have this on the log: [Wed Oct 24 11:26:31 2012] [error] [client xxx] PHP Fatal error: Out of memory (allocated 28049408) (tried to allocate 201335 bytes) in xxx on line 2139, referer: xxx I have read many many posts here, but I think there is something fundamental that I'm missing - If I understand correctly some php script tried to allocate 200K after allocating 28MB, and fails to do so. First question is: should this cause the apache to crash??? Next, I tried to look at 'top' command while I do my little test. Indeed I see 7 httpd processes, each reserving about 30MB - which explains why my RAM runs out. How do I prevent apache from creating new processes until it's out of memory? I tried configuring /etc/httpd/conf/httpd.conf like this: <IfModule prefork.c> StartServers 1 MinSpareServers 1 MaxSpareServers 1 ServerLimit 1 MaxClients 1 MaxRequestsPerChild 100 </IfModule> But got the same exact result! What am I missing? Thanks a lot!

• v2v of RHEL5 box - issues with retaining MAC address

  - by Alex Berry

  For the last week we have been troubleshooting a customer's Red Hat Virtual Machine running on ESXi. We've been using Veeam to try to create a replica off-site and have been having getting it to work on a decent schedule and recently we noticed that there were issues with orphaned snapshots while looking at the datastore. You can see several snapshots in the same folder and it's causing issues with replication and backup, so we decided the cleanest way was to v2v the machine to another datastore so that we had a clean single-vmdk setup to work with, this is where our trouble started. We first started off with a v2v using vmware converter and connecting to the powered on machine as we were having issues doing an offline v2v. This copied fine but when I tried to set a static MAC using this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=507 the new VM wouldn't take the address, it simply obtained a new MAC, received a dhcp lease and then would only boot up to a blank red screen, never the login screen. So the next step was to do an offline v2v, once we finally got it working. Same thing, followed the kb to the letter and still it wouldn't take the MAC. I then tried it again and upon completion I compared both old and new VMX file, copying every identifier and variable possible, then unregistered both VMs, uploaded the new VMX file and booted, only to see the same results. Finally I did the same as above but I copied the disk using DD to a second attached vmdk and then attached this to the new VM, and still no luck. After downloading the modified VMX file after the first boot and comparing it to the original I created I found that the bios uuid had changed from the one I typed in manually, so I'm assuming this may be the snagging point, but I have no idea. I've never had this issue before on a P2V and I'm just wondering if someone could shed some light on this, maybe it's to do with RHEL licencing?

• (manually configured) kernel update leaves wireless in a mess

  - by Mala

  I recently upgraded my kernel from 2.6.31-gentoo-r6 to 2.6.32-gentoo-r7. In both cases, I configured everything manually. However, since the upgrade, my wireless card appears to be on the fritz. It will connect to networks just fine, and remain connected, but can only access the internet (and other hosts on the network) for about 3 seconds after connecting. Reconnecting to the network appears to fix the problem... for another 3 seconds or so. The problem is "solved" by booting into the older kernel. The relevant lspci entry is 02:00.0 Network controller: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection I'm pretty sure I have the correct drivers enabled in the kernel Device Drivers ---> Network device support ---> Wireless LAN (IEEE 802.11) ---> <*> Intel Wireless Wifi [*] Enable LED support in iwlagn and iwl3945 drivers [*] Enable Spectrum Measurement in iwlagn driver [*] Enable full debugging output in iwlagn and iwl3945 drivers <*> Intel Wireless WiFi Next Gen AGN (iwlagn) [*] Intel Wireless WiFi 4965AGN [*] Intel Wireless WiFi 5000AGN; Intel WiFi Link 1000, 6000, and 6050 Series I tried with the other intel drivers enabled as well (iwl3945) and no difference. Is there something stupid I'm missing? Is there something I have to recompile after upgrading the kernel (a la nvidia)? Thanks Mala

• How to correctly configure DNS for Icelandic domains and Plesk

  - by Leonard Challis

  I have a domain registered with ISNIC (domain.is). They only let you set nameservers that pass their requirements. I've been told it's this requirement that I need to fix: Nameserver must be consistently registered in DNS, i.e. its own A resource record must be available and a corresponding PTR resource record as well. I allocated two new IP addresses from my server host and at that point set their PTR records to ns0.domain.is and ns1.domain.is. After that I created two A records for that domain in Plesk, again ns0. and ns2.domain.is with their respective IPs. Next, I went to the ISNIC page to register my nameservers, along with their IP addresses I'd allocated and this worked perfectly for both without error. So the final job was to set the nameservers for the domain via ISNIC's control panel, however when I try, I'm getting this error: Test results for "NS0.DOMAIN.IS": The nameserver ns1.vps123.vpsprovider.com is not consistently registered in DNS (ns1.vps123.vpsprovider.com => 1123.123.123.123 => vps123.vpsprovider.com) The nameserver ns0.vps123.vpsprovider.com is not consistently registered in DNS (ns0.vps123.vpsprovider.com => 1123.123.123.123 => vps123.vpsprovider.com) The nameserver ns0.DOMAIN.IS is missing from the NS record set for DOMAIN.IS Test results for "NS1.DOMAIN.IS": The nameserver ns1.DOMAIN.IS is missing from the NS record set for DOMAIN.IS The nameserver ns0.DOMAIN.IS is missing from the NS record set for DOMAIN.IS This is really at the limits of my DNS knowledge I'm afraid. It feels like I'm close but maybe missing a vital part, linking the nameservers in Plesk or something?

• HP Proliant DL380 G4 - Can this server still perform in 2011?

  - by BSchriver

  Can the HP Proliant DL380 G4 series server still perform at high a quality in the 2011 IT world? This may sound like a weird question but we are a very small company whose primary business is NOT IT related. So my IT dollars have to stretch a long way. I am in need of a good web and database server. The load and demand for a while will be fairly low so I am not looking nor do I have the money to buy a brand new HP Dl380 G7 series box for $6K. While searching around today I found a company in ATL that buys servers off business leases and then stripes them down to parts. They clean, check and test each part and then custom "rebuild" the server based on whatever specs you request. The interesting thing is they also provide a 3-year warranty on all their servers they sell. I am contemplating buying two of the following: HP Proliant DL380 G4 Dual (2) Intel Xeon 3.6 GHz 800Mhz 1MB Cache processors 8GB PC3200R ECC Memory 6 x 73GB U320 15K rpm SCSI drives Smart Array 6i Card Dual Power Supplies Plus the usual cdrom, dual nic, etc... All this for $750 each or $1500 for two pretty nicely equipped servers. The price then jumps up on the next model up which is the G5 series. It goes from $750 to like $2000 for a comparable server. I just do not have $4000 to buy two servers right now. So back to my original question, if I load Windows 2008 R2 Server and IIS 7 on one of the machines and Windows 2008 R2 server and MS SQL 2008 R2 Server on another machine, what kind of performance might I expect to see from these machines? The facts is this series is now 3 versions behind the G7's and this series of server was built when Windows 200 Server was the dominant OS and Windows 2003 Server was just coming out. If you are running Windows 2008 R2 Server on a G4 with similar or less specs I would love to hear what your performance is like.

• How do you recreate the System Recovery environment in Windows 7?

  - by Howiecamp

  I'm running Windows 7 Home Premium RTM (64-bit) and I want to take advantage of the system recovery tools (eg the Command Prompt) without using the Windows 7 DVD. My understanding is that this environment (WinRE) should be installed to your HDD by default as part of the Windows 7 installation. However, when I hit F8 on boot and select "Repair", I get: Windows failed to start. A recent hardware or software change might be the cause. To fix the problem... Status: 0xc000000e Info: The boot selection failed because a required device is inaccessible. The "Info" line seems like the smoking gun. My next step was to boot from the Windows 7 DVD, and choose "Repair". It indicated my Recovery Environment wasn't on the Windows 7 boot menu (perfect) and offered to fix it. I said yes and rebooted, however same issue as above. In addition, when I booted in to Windows 7 and I looked at the boot menu options, the recovery/repair option was not there. Only my Windows installation. Finally, I ran the Disk Management tool (diskmgmt.msc) and took a look at the contents of my "System Reserved" partition (which was set to "Active" as normal). It's unclear to me what the contents should look like, however it is my understanding that the WinRE environment gets installed to this partition. (As part of the above troubleshooting I followed http://superuser.com/questions/25728/how-to-fix-windows-7-boot-process which lead to http://www.sevenforums.com/tutorials/668-system-recovery-options.html).

• How to correctly set GNU Screen to display currently running program in hardstatus

  - by johnny_bgoode

  I posted this question on SuperUser but it's hardly getting any views, so I thought I'd ask here as well. In bash, to display the name of the current program in the GNU Screen hardstatus line takes only two configuration lines. First, tell screen what the end of your prompt normally looks like, and supply a default title for a window when you are sitting at in the shell: shelltitle "$ |bash" Next, place this escape sequence in the PS1 variable, before the characters that normally terminate the prompt '$ ' in this case: \033k\033\\\ This technique works, to a point. The hardstatus window title is updated to the name of the currently running program, and then switches back to the default title shortly after execution is finished. One major problem, however, is that this escape string is not escaped itself, causing line-wrapping problems with commands longer than the initial line. This was annoying, so I set out looking for a solution. Turns out, simply escaping the previous escape sequence corrects line wrapping: [\033k]\[\033\\\] Great! My hardstatus window title still updates to the name of the currently running program, and now my longer commands wrap to the second line correctly. However, with this new escape sequence in my PS1, screen updates the window title to the actual command I am typing, not simply the name of the current program once it is executed. I am wondering, has anyone gotten this working correctly - i.e. line wrapping and proper updating of the hardstatus window title? Thanks!

• Why is the wrong name server information at crsnic.net & gtld-servers.net ?

  - by danorton

  Did I screw this up? I don’t even know how this might have happened, so I’d like to learn. I’m trying out HostGator’s reseller service and I bought a domain name through it, but I didn’t want the default name servers and so I changed them during the registration. After registration the domain name record is correct everywhere except at whois-servers.net and whois.crsnic.net and it looks like the DNS network is using that same information. $ whois -h whois.enom.com. example.com ...

• Turning on Bluetooth disables wifi on Yoga 2

  - by Yostage

  I have a Lenovo Yoga 2. The moment that I turn on bluetooth, the wifi drops out - I lose connection, and connecting again shows "connection failed". If I turn the bluetooth off, wifi can reestablish fine. I've tried lots of different combinations of drivers for both the wifi and the bluetooth, but no combination has has changed this behavior yet. I've read some speculation that the cards have insufficient shielding, but that seems like kind of a large flaw to ship with. I've tried with a Carbon X1, a Yoga 2 Pro, and a Yoga 2 all next to each other on the desk while running InSSIDer. The X1 and the Y2P don't lose wifi connection when the bluetooth turns on, but the Y2 does immediately. The Y2P and the Y2 are running the same drivers for bluetooth and wifi, and appear to have the same wireless card internally. During the failure state, InSSIDer still sees signal strength for my network, but I cannot connect to it. stats: the card that comes in the laptop is an Intel Wireless-N 7260 Intel Bluetooth driver is at 17.0.1401.422 Intel Wireless driver is at 17.0.2.5 Windows 8.1 x64 Home wifi is a Medialink MWN-WAPR150N

• Windows Server 2012 Hyper-V very slow

  - by Matt Taylor

  I have been running several Hyper-V VMs on Windows Server 2008 R2 for the past couple of years and enjoying perfectly adequate performance for my testing/development/r&d environments. I'm a software developer so my hardware knowledge is basic however I built the rig using: •Gigabyte GA-X58A-UD3R Intel X58 (Socket 1366) DDR3 Motherboard •Intel Core i7 960 3.20GHz (Bloomfield) (Socket LGA1366) •24GB triple channel RAM The host OS is running on an OCZ SSD and all the VMs are running on a 2TB Marvell SATA3 RAID 0 array consisting of 2 Western Digital Caviar Black 7,200rpm drives. I have tested the speed of the 2TB drive and appear to be getting less than 3Mbs but it can adequately run a 4 VM farm including a DC, (SQL) database and IIS application servers. I recently upgraded the SSD on which the host runs to a 256GB OCZ Vertex 4 and took the opportunity to upgrade to Windows Server 2012 and installed the Hyper-V role. I tried importing one of my existing Windows Server 2008 R2 VMs (and converted it to .vhdx) plus I have tried creating a brand new Windows Server 2008 R2 VM but both are running extremely slowly and I can see nothing obvious using the host and guest Task Manager/Resource Monitor tools. In both cases the VM has 8GB RAM (fixed), 4 CPUs, fixed size HD (not expanding) and is using an external virtual network running on a separate NIC to the host. I have upgraded the BIOS to the latest available version and checked the virtualization settings. I have run out of "obvious" (to a developer) things to check/configure and my next option will be to re-install the host OS but before I do I would very much appreciate any advice from any experts out there. Thanks

• Mirroring the Global Address List on Blackberries

  - by Wyatt Barnett

  In times immemorial, back in the day when men were men and blackberries still took AA batteries, we rolled them out to our users for our 100 person operation. At that time, there was no such thing as address list lookups, so we were forced to hack a bit. The ingenious hack we came up with was to mirror the GAL as a public folder and then synch up blackberries to that. While there have been a few downsides here and there, they have been mere annoyances. And our users, having grown fat and prosperous in the intervening years, have been used to seeing every single employee and department here listed on their hand-held automatically. Alas, it appears that Outlook 2010 breaks this functionality as Blackberry desktop manager is completely incompatible with it. Moreover, this presents us with an opportunity to change things for the better given that public folders are going away next time we upgrade exchange. So, we are in search of a tool or technique that will allow us to mimic current functionality--that is to: Push an essentially arbitrary list of ~100 contacts to blackberry address books Said list shall be centrally updated Without requiring desktop manager or exchange public folders. Any suggestions, crowd?

• What is proper relationship between /etc/hosts and DNS A records for a Linux server?

  - by MountainX

  I have an Ubuntu server. It is going to be a web server with a URI of www.example.com. I have a DNS A record pointing www.example.com to the server's IP address. Let's say I pick "trinity" as the hostname for this server. I want to set up the DNS records correctly. I need reverse DNS to www.example.com, so a CNAME for www.example.com doesn't seem appropriate. Here's my question: Is it considered best practice to set up two DNS records (which in my case would likely be two A records), one for www.example.com and one for trinity.example.com, both pointing to this server's IP address? (Or, even if it is not accepted as a best practice, is it a good idea?) If so, would the following be a proper /etc/hosts file? $ cat /etc/hosts 127.0.1.1 trinity.local trinity 99.100.101.102 trinity.example.com trinity www.example.com This server is a Linode and Linode's docs seem to imply that the above approach is best (if I am reading them correctly). Here's the relevant section. I bolded the line that seems to apply here. Update /etc/hosts Next, edit your /etc/hosts file to resemble the following example, replacing "plato" with your chosen hostname, "example.com" with your system's domain name, and "12.34.56.78" with your system's IP address. As with the hostname, the domain name part of your FQDN does not necesarily need to have any relationship to websites or other services hosted on the server (although it may if you wish). As an example, you might host "www.something.com" on your server, but the system's FQDN might be "mars.somethingelse.com." File:/etc/hosts 127.0.0.1 localhost.localdomain localhost 12.34.56.78 plato.example.com plato The value you assign as your system's FQDN should have an "A" record in DNS pointing to your Linode's IP address. For more information on configuring DNS, please see our guide on configuring DNS with the Linode Manager.

• ExpressCache not working after Windows 8 reinstall on Samsung Series 7 Gamer

  - by Morven

  I have a Samsung Series 7 Gamer laptop which came with Windows 8. After doing a reinstall of Windows, the ExpressCache software is no longer caching. Running "eccmd -info" shows me that the software is present and it has the MSATA drive partition configured. However, it's not actually caching anything. These are the results after having the system booted for days: C:\windows\system32eccmd -info ExpressCache Command Version 1.0.94.0 Copyright¬ 2010-2012 Condusiv Technologies.

Anyone know where to look next? The only guides I can find deal with ExpressCache not being present or not having a configured drive.

• nginx & php-fpm and custom header

  - by nixer

  I would like to pass some custom header (ACCESS_TOKEN) from client RESTful application (JS) to application server (php-fpm). I had read that nginx should pass all http headers to php, but somehow it does not come to my php :( I can see it in firebug http://o7.no/N6DM7q but can't see it in $_SERVER variable. it just does not exist in $_SERVER array. I'm thinking that i need to pass it manually. Now my config looks like that: location @php-fpm { include /etc/nginx/fastcgi_params; fastcgi_pass unix:/tmp/php5-fpm.sock; fastcgi_param REQUEST_URI /index.php$request_uri; fastcgi_param SCRIPT_FILENAME /htdocs/index.php; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param DOCUMENT_ROOT /htdocs; } } and when I add new line in location definition: location @php-fpm { include /etc/nginx/fastcgi_params; ... fastcgi_param ACCESS_TOKEN $http_access_token; } } or even if i will add it into fastcgi_params file it does not help :( if I put into location part next line: fastcgi_param ACCESS_TOKEN $http_access_token; then in php it has empty value :( how I can pass custom header from client to backend (php) via nginx ?

• Thecus N5200, disk has dropped out of RAID5

  - by Anders Ekdahl

  We have a Thecus 5200 NAS here at work with five WD Caviar Black 2TB disks in a RADI5 array. Yesterday, disk 4 dropped out of the array, and in the NAS web interface there's a warning about the RAID array being "degraded". When I go into Storage - Disks, disk 1 and 4 has a warning next to them. When I click on the warnings, this information about the disks are displayed: Tray Number 4 Model WD2001FASS-00W2B Power On Hours 2403 Hours Temperature Celsius 34 Reallocated Sector Count 66 Current Pending Sector 1447 Raw Read Error Rate 61 Seek Error Rate 0 Hardware ECC Recovered N/A Tray Number 1 Model WD2001FASS-00W2B Power On Hours 2403 Hours Temperature Celsius 32 Reallocated Sector Count 0 Current Pending Sector 1465 Raw Read Error Rate 0 Seek Error Rate 0 Hardware ECC Recovered N/A I'm not really an expert on either disks or RAID arrays. Does this indicate that the fourth disk is damaged, and needs to be replaced? And what about disk number one? It has a warning, but it's still in the array. Is it safe to add the fourth disk back into the array as a spare? I can't find any way to add it back as a it were before.

• How can I get Windows 8 to automatically disable touch when I am using my Wacom pen and turn it back on when I am not

  - by Robert

  I have an HP convertible tablet computer which I just upgraded to Windows 8. The problem (which existed under Windows 7 as well) is that this tablet has both a capacitive touch screen (with multi-touch) AND a wacom-type tablet built in to the screen that works using electro-magnetic resonance with the provided stylus. My Use Case: Most of the time I am happy using my fingers and the touch interface for navigation and whatnot. However, when I want to get down to serious note-taking/drawing, I want to use the wacom functionality. The problem is that any comfortable writing position has me resting my arm/hand on the screen, which activates the touch technology (despite supposed palm-detection algorithms) and completely screws up my input paradigm. My Ideal Solution: Ideallly, since wacom technology senses when the pen is "close" to the screen, I would love to have touch be automatically disabled whenever the wacom pen is detected, and turned back on when it is out of range. this would allow me to seamless switch between the two input methods, and since I NEVER want to use both at once would work perfectly for me. An acceptable alternative: As a next best option, It would be great to be able to turn off the touch functionality (leaving the wacom in place) whenever I entered specific apps (e.g. OneNote, Photoshop, Gimp, Pencil, etc.) and then have it turn back on when I left that app.... As a worst case at least lets me use my PC option: If I could create a shortcut (tile or otherwise) that flips the touch on and off without going all the way through the nested computer settings, that would be better than nothing. Thanks in advance for the help with 1 or more of the above.

• ESXi 5 Guests will not boot

  - by Adrian

  I have a problem with Guests not booting under VMWare ESXi 5.0 on my IBM x3550M3 server. Note: Investigation eventually determined that problem was with the VMware client on a Lenovo Edge laptop, the only Windows box available in a Linux IT shop. vSphere Client v4 and v5 duplicated behavior on the Lenovo Edge. As indicated in the comment to the accepted answer, replacing the workstation with one using different video was the "fix" for this particular issue. The ESXi host boots just fine. The Client connects just fine. Guests can be configured but do not successfully boot. The initial guest memory consumption jumps up to 560MB and drops down to 40MB after a few seconds. Initial CPU usage is 1 full CPU (3000Ghz per the chart) and immediately drops downm to 29Mhz. Guests do not display any output in the Console tab but show a state of 'Powered On'. No errors in the Events tab. Switching Guest from BIOS to EFI makes no difference. VMs are listed as Version 7 and the behavior is duplicated across all availabled Guest OS flavors. Problem also duplicated when server is booted up in Legacy Only mode. Logs do not contain anything particularly suspicious. Edit: No firewalls, routers, or VLANs in between the client and server. Edit 2: We have tried to Boot Guest into BIOS screen at Next Boot checkbox in the Guest Setting. Was not successful. Edit 3: 500GB datastore with 1 40GB VM on it. Plenty of space. Edit 4: Guests copied from my old ESXi 4 server DO NOT boot on the ESXi 5 system. Initially it complains about too little Video RAM being configured for the default 2500x1600, but it still doesn't work properly even after I bump the Video RAM settings or switch it to Auto-Detect.

• replacing buffalo lonkstations with FreeNAS, overall backup strategy, am I on the right path?

  - by Shreko

  We've been using 2 Buffalo LinkStations of 320Gb each for shared directory and employee's server storage (around 20 employees). So only documents (word, excel, cad drawings etc.) and database backup of the main application server (ERP, Accounting) 1 buffalo box serves as a main one, located at the server room, next to the main application server and the other buffalo box is located on the opposite side of the building (for fire protection) in a secure storage room and backs up the first one. We also have several external HDs that backs up everything from the buffalo box for an offsite backup. After 3.5 years of using these, capacity is a main limitation, I'm planning a replacement and would like to use FreeNAS (we already use monowall with great success). I would like to keep it simple and continue similar setup, building two low power boxes with 1 hd (2Tb) each. Is low power atom mobo OK? Not sure about HDs? I've read on this site somebody mentioning more seagate ES2 as more reliable and better performing. How would those eco/green drives compare. We've been pretty happy with speed of Buffalo boxes and I don't want my users to notice any slowdown. Any suggestion?
