  • Amazon EC2 - Free memory

    - by Damo
    We have an amazon ec2 small instance running and over the past few days we noticed that the memory is going down and down. On the small instance, we are running apache and tomcat6 Tomcat is started with the following JVM parameters -Xms32m -Xmx128m -XX:PermSize=128m -XX:MaxPermSize=256m We use nagios to monitor stuff like updates to apply, free disk space and memory. Everything else is behaving as expected but our memory is going down all the time. Our app receives approx half a million hits a day When I shutdown apache and tomcat, and ran free -m, we had only 594mb of memory free out out of the 1.7gb of memory. Not much else is running on the small instance and when running the top command I cannot see where the memory is going. The app we run on tomcat is a grails webapp. Could there be a possibility that there is a memory leak within our application? I read online and folks say that a small amazon instance is perfect for running apach and tomcat. I found a few posts online that showed how to setup apache and tomcat to limit the memory usage and I have already performed those steps. The memory is not being used up as quick but the memory is still decreasing over time. We have other amazone ec2 small instances running grails apps and the memory is fairly standard on those nodes. But they would not be receiving as much traffic Just to add, when I run the top command on the problem server, I cannot see where all the memory is being used Any help with this is greatly appreciated The output of free -m when run on my server is as follows total used free shared buffers cached Mem: 1657 1380 277 0 158 773 -/+ buffers/cache: 447 1209 Swap: 895 0 895 In your opinion, does this look ok? At what stage would the OS give back memory, would it wait to the memory reaches 0% or is this OS dependent?

  • How to control/check CheckPoint rules changes (and another System events)

    - by user35115
    I need to check/control all system events on many CheckPoint FW1 - don't misunderstand - not rules triggering, but events such admins log on, rules changes and etc. I found out that I can make an log export using 2 methods: Grab logs Use special script that redirect Checkpoint log entries to syslog, FW1-Loggrabber But it's not clear for me does such logs also contain information that i need (admins log on, rules changes)? And If yes is it possible to filter events? I also suppose, that if system bases on *nix platform it must be a ploy - use based functions of the system to do what i want. Unfortunately i don't know where to "dig". May be you know? Updated: New info "FW-1 can pipe its logs to syslog via Unix's logger command, and there are third party log-reading utilities" So, the main question is how do my task in the best way? Has anybody already resolved such problem? P.S. I' m new with CheckPoint, so all information will be useful for me. Thank you.

  • Are these hardwares compatible?

    - by Tom Kaufmann
    I am trying to upgrade my new machine but I want to do it myself. This is my 1st attempt at building system. After carefully reading reviewing feedback and my budget I have decided to select the below listed components. Can anybody let me know are they compatible or not? Transcend 64 GB 2.5" SATA Solid State Drive Asus GeForce GTX550 1GB DDR5 ENGTX550 TI DI/1GD5 Graphics Card Seagate Barracuda 1 TB HDD Internal Hard Drive Cooler Master eXtreme Power Pro 600 Power Supply Intel Core i5 2500K Sandy Bridge 3.30 GHz 95 W 4 Core Desktop Processor Intel DX79TO Motherboard Corsair CMZ8GX3M2A1600C9 8 GB DDR3 SDRAM 1600 MHz Dual Channel Kit Desktop Memory Sony AD-7260S-ZS Internal DVD Writer - Black Cooler Master Hyper TX3 EVO Intel CPU Cooler Cooler Master Elite 335U Cabinet LG E2051T 20.1 Inch SuperSlim Monitor Is any of these hardware components incompatible with I5 2500K? If you have any other suggestions for selecting any other harwdware that can boost up my performance or lower my cost while having the same performance, please suggest. But my primary questions is whether they are compatible or not! Any help is appreciated. Thank you.

  • Partitioning of Ubuntu server which will use OpenVZ and encrypted partitions (unlocked through SSH l

    - by DeletedAccount
    Hi, I'm about to install a server. Some context: My HDD is 1 TB and I have 2 GB RAM Ubuntu Server Lucid Lynx AMD 64 I will use OpenVZ and have most functionality separated into containers. To support disk quotas I need to use ext3 (not ext4) for the container partition. Each time I reboot the server I want to be forced to login through SSH and mount the encrypted partitions by typing my password (if someone steals the server, no critical data should be available). I want to have as much as possible encrypted. Yet I want to be able to login through SSH as I don't have a monitor or keyboard at the server. I am not sure how big I need my partitions to be. Being able to resize them later would be nice. I guess it implies using LVM? But the manual partition mount using SSH is also very important (in fact it's more important, if I have to pick one). How do you recommend that I partition the HDD? If I have daemons which needs the encrypted partitions, will they fail and can I just restart them after mounting the needed partitions?

  • Remote Desktop svchost (networkservice) & lsa.exe high cpu usage, hangs on welcome screen

    - by Rohan1
    We have deployed an RDS Farm with 12 virtual RDS servers using Hyper V. Currently some users are not able to log on. After passing credentials to the connection broker, the session hangs on the "Welcome" screen. Using resource monitor we've seen that svchost (with the "networkservice" service) has a CPU usage of 50%, when viewing the wait chain on the process it displays that it's waiting for a lsa.exe to finish. We can't kill any of the users processes, even when trying with taskkill /f. Suspending lsa.exe did work but didn't have any effect. The networkservice also couldn't be restarted. Also, if this happens, the current users logged on to the RDS server can't be displayed. Task manager crashes when viewing the users, RDS service manager crashes when viewing the users (even remotely) and the cmd command "query session" doesn't work. No antivirus is installed on the RDS server. The only thing we can do is rebooting the server, which is not an option because of the fact that other users are in active sessions. Does anyone have ANY idea what's going on? We didn't encounter this in our pre-production setup.

  • Web shortcuts (.url) not working on Windows 7

    - by jpbochi
    I'm experiencing several symptoms, but I believe they are all related to web link files not working. First, I can't create we link files anymore. When I try New Shortcut and put an URL, I get the following error message: Second, existent shortcuts are not working. The default context menu action (or double-click) is Print, which simply prints an empty page. If I try to see its properties, there's no URL there. Third, IE bookmarks are also not working. One difference is that the default action is Open, IE does nothing when I click it. Adding a new bookmark only creates one more dead link file. I'm almost sure this problem occurred after I tried to install IE 7 on Windows 7. Unfortunately, it didn't work because the OS seems to be bound to IE 8. I already tried to reinstall/repair IE 8, but it made no difference. Does anyone experienced a similar problem? I need a working solution, but I welcome any reasonable suggestion.

  • Server specification recommendation

    - by foo
    To cut the story short, I can't buy an item (server/cpu/motherboard/ram) that costs more than USD 330. However, I can combine them, meaning, I can buy a CPU that costs USD 330 and motherboard that costs USD 330. With this limitation, I can't buy a powerful 1U server which will definitely costs me more USD 330. With that in mind, I was hoping to build a powerful desktop PC which will be used as a database server. However, through my experience, desktop PC doesn't last very long, usually the motherboard will just die by itself after 1 or 2 years. So, what would you guys recommend me to buy with this kind of budget? Every item must be <= USD 330. Will be used as a MySQL server. RAID would be nice. 1TB is pretty big for my data. I do not need external graphic card (onboard would do just fine), mouse, keyboard, monitor. Linux friendly. One ethernet port is good enough. It's important that those hardware is made of components that will last long (at least 3 years or something). The server will be placed in an air conditioned room, but a good ventilation for the server is always preferred. I won't overclock it. Intel processor is preferred. Thanks in advance.

  • How can one restrict network activity to only the VPN on a Mac and prevent unsecured internet activity?

    - by John
    I'm using Mac OS and connect to a VPN to hide my location and IP (I have the 'send all traffic over VPN connection' box checked in teh Network system pref), I wish to remain anonymous and do not wish to reveal my actual IP, hence the VPN. I have a prefpan called pearportVPN that automatically connects me to my VPN when I get online. The problem is, when I connect to the internet using Airport (or other means) I have a few seconds of unsecured internet connection before my Mac logs onto my VPN. Therefore its only a matter of time before I inadvertently expose my real IP address in the few seconds it takes between when I connect to the internet and when I log onto my VPN. Is there any way I can block any traffic to and from my Mac that does not go through my VPN, so that nothing can connect unless I'm logged onto my VPN? I suspect I would need to find a third party app that would block all traffic except through the Server Address, perhaps Intego Virus Barrier X6 or little snitch, but I'm afraid I'm not sure which is right or how to configure them. Any help would be much appreciated. Thanks!

  • Is it possible to recover from the Windows 8 refresh feature?

    - by Warren P
    The intention of the Windows 8 RTM (released version) Refresh feature is to restore the system to the way it was when I first installed. It didn't though. Almost everything that came in the start-screen (not a menu any more) is gone, not just third party apps I installed, but EVERYTHING other than the icon for internet explorer, and the icon for the store, and the desktop, were wiped. Out of the box Windows 8 had a pretty large list of things installed, and it seems that the Refresh feature wipes all of them out. Is it possible to really get the system back to a fresh install state, or should I just re-install from the DVD I made? (I have access to Windows 8 RTM, legally through the MS Action Pack subscription.) I suspect that if I create a new account, I might get a new desktop with a default set of icons, but I'm hoping it might be possible to do this without using a different login. The second problem with Windows 8 refresh is it seems to trash the ACL's on my C: drive, taking all permissions away for access to the C: drive, making nothing on it visible or readable to my primary and only login account. I believe it might be possible to undo the damage done by the "refresh" with some judicious use of icacls from the command prompt.

  • 1 PC, 2 consoles (as in 2 monitors, keyboards and mice)

    - by ciuly
    I have this desire to "kill 2 birds with one shot". Currently, I have 1 server running round the clock, 1 laptop that runs about 8 hours a day, 7 days a week, and a desktop that runs about the same length of time. All 3 are ... old, to say the least. So there is a great need to upgrade (well, the server might handle its job for another year or so, but that only depends on how much time I have to put it to "work"). Now, I'm "dreaming" of only one PC. I'm thinking vmware's ESX. So there will be a VM for the server, a VM for the "laptop" and one for the "desktop". And obviously I'll have to somehow "link" a set of monitor/keyboard/mouse with one of the laptop/desktop VMs. The server doesn't need such things, obviously (it doesn't have them at this moment either). Is something like this possible? ESX is not a requirement, it's just something I found that answers part of my problems, but there still remains the 2 KVM set that needs connecting and "linking" to appropriate VM. Why I would want to do this? well, first of all, it's much cheaper to upgrade one PC than 3. Then, the power consumption is obviously lower. Plus the extra space.Plus it allows me to better separate networks and services. Thanks.

  • What's Keeping My Computer Awake?

    - by phantomdata
    Hey guys, First the question; How do I figure out what is preventing my Windows 7 computer from going into sleep mode? Second; some background... I've been struggling with this for a few days and am utterly perplexed. I setup sleep mode on my Windows 7 PC a few weeks ago, and all was well. The PC would sleep as expected and I was snuggly in knowing that my computer was saving power and some wear and tear on the components (we'll leave the 'is it better to sleep' debate for another thread/day, please don't start it). Well, I noticed the other night that my system stopped ever going to sleep. I set the sleep time down to 1 minute and wandered fully away from the PC (ensuring that no errant mouse or keyboard movements would occur) and the PC never went to sleep. I've also observed this over longer intervals as well, such as overnight. I have sleep mode enabled, of course "multimedia settings - When Sharing Media" is set to allow the computer to sleep. "powercfg -lastwake" show nothing of interest, since it never goes to sleep and can't wake up. "powercfg /requests" shows 3 entries - all "[DRIVER] ?". I assume that 2 of these are my mouse and keyboard - as I've recently used them to run the powercfg command. I'm at a loss for the third though. I've unhooked all USB peripherals save for my keyboard and mouse. Wake on LAN is disabled in my BIOS. I know that you can disable all apps from waking/preventing sleep - but I want the ability to remain for those apps that do legitimately need to keep the system awake. So; does anyone know of a way to figure out what the 3rd phantom "[DRIVER] ?" is in powercfg /requests?

  • Experience with asymmetrical (non-identical hardware) SQL Server 2005 / Win 2003 cluster

    - by user24161
    I am reasonably good at dealing with SQL Server clusters; I am wondering if folks have experience, good or bad, using a mix of different models of servers from the same vendor in one SQL 2005 cluster. Suppose: I have one more powerful, more RAM, more shizzle box and one less powerful, less memory, less shizzle box bound together in a 2-node cluster. These would be HP DL380 and 580 machines (not that it should matter) I understand AND automate the process of managing memory for each SQL instance, so there's no memory contention when SQL instances fail over. Basically I am thinking a CLR proc will monitor the instances and self-regulate memory caps on each instance, so that they won't page or step on one another. I get the fact the instances might be slower and or under memory pressure if they share a "lesser" node, and that's OK. The business can deal with a slower instance in a server-problem scenario. Reasonable? Any "gotchas" to watch out for? More info 10/28: doing some experiments with a test cluster I find that reconfiguring max/min memory is OK PROVIDED the instance isn't already under memory pressure. If I torture the system with a huge query that demands a big chunk of RAM, and simultaneously adjust the memory allocation to a smaller value than what is being actively used, it's possible to run the instance out of memory and have it halt and restart itself (unhappy situation). Many ugly out-of-memory messages in the error log, crashing, burning... It's an extreme case, but good to know. Seems, then, that it would only be really safe to set this on startup of the instance, as in have a startup script that says "I am on node1, so my RAM settings are X or I am on node two, so they are Y," like this: http://sqlblog.com/blogs/aaron_bertrand... Update: I am testing a SQL Agent + PowerShell solution described in more detail here.

  • Windows 7 host with Ubuntu Guest and a performance hit, memory locks?

    - by Cyrylski
    I have a brand new Lenovo T510 with Core i5 and 4GB of RAM with Windows 7 on it. I Installed Ubuntu 10.10 in a Virtualbox. For some reason system gets really slow on this setup which makes me really angry. There's a video card shared with full 3D support enabled and 1GB of RAM allocated for the Ubuntu machine. It may sound stupid, but WHY is the whole memory consumed in an instant when I run Virtualbox? I struggled for like 10 minutes restraining myself from a brutal reset, and now everything runs smooth but memory "in use" in Resource Monitor is 3GB flat with only Chrome running. I'm new to Windows 7, but I'm really disappointed with performance at this point... I used to work in a different environment with much slower hardware and there was no such problem (WinXP over Ubuntu, 1GB out of 2GB allocated for WinXP guest on intel GMA). This is, until I clogged RAM totally there. But I was capable of running Chrome, Firefox and Apache server on a 1GB RAM in Ubuntu there and Photoshop CS4 on Windows XP and it worked. In this case I can't go beyond setting up Ubuntu properly. I bet I'm doing something wrong.

  • Cloned Centos 6.4 websrver for test purpose. Virtual host, .htaccess, redirecting url issue

    - by Shogoot
    I see similar questions, but not my exact challenge. What I have done so far I cloned a prod server over to a vmware to use it as a test server for new functionality I'm going to write. I'm not a sysadmin by trade, but I'm new to this company and I have to do some thing that are outside of my comfort zone (thats a good thing :) ) The prod server has 2 sites on it s1.com and s2.com. In /html/s1/, /html/s2/ there's an .htaccess file under each s*/. Looking like this: RewriteEngine ON RewriteBase / RewriteCond %{QUERY_STRING} id=([0-9]+) RewriteRule ^.* %1.htm RewriteCond %{QUERY_STRING} page=modules/checkout RewriteRule ^.* order.php RewriteCond %{QUERY_STRING} page=pages/sidekart RewriteRule ^.* pages/sidekart.htm The issue is that s1 has a lot of pages that really belongs under a third domain s3, the rule in line 4 and 5 redirects them to /html/s1/. An example of such URL is: s3.com/?page=modules/product&id=521614 I'm trying then to get those URLs (without modifying the URL) to redirect to s3's /html/s3/ server structure, which I set up making a new virtualhost s3 in test servers httpd.conf with a test3.com as servername and changing the other sites to tests1.com and tests2.com, and adding .htaccess also to this s3 root directory, and making a html/s3/ directory structure I populated with an index.html, etc. But, when I take the same URL (s3.com/?page=modules/product&id=521614) changing it to tests3.com/?page=modules/product&id=521614, I get s1's index page showing up in my browser. I've poked around about a day now and i cant figure out why this happens.

  • Exchange 2003 inbound routing issue

    - by user565712
    Just recently we started experiencing inbound routing issues. Email adddressed to [email protected] is intermittantly translated to [email protected]. This is happening for several users and, as stated, is intermittant. I don't know where to start looking for the solution. Is this an Exchange issue? A DNS issue? We have a single Exchange server inside our network with an FQDN of server.domain.local with a single SMTP Virtual Server. The Advanced properties of the Delivery tab of the Virt Server has an empty Masquerade Domain textbox and the value for the FDQN text-box is set to the domain itself, domain.com. The DNS record for domain.com is a CNAME entry referencing www.domain.com. Is this somehow related to the problem? I checked the headers of the inbound messages that generated NDRs as a result of being sent to [email protected] and nowhere in the header is www.domain.com mentioned. To make my life even more difficult, we use Postini as a third-party SPAM filtering service. Our MX records point to the Postini servers and Postini delivers the messages to our server. Perhaps it is Postini that is mucking things up? sigh I'm having trouble with this one and the intermittent aspect is making it that much more difficult for me. Any ideas?

  • Win 7 64 with 8 gig of ram, getting running low on memory errors.

    - by John
    I have a new Dell laptop running Win7 64 with 8 meg of ram. If I leave the system running overnight I start getting low memory errors the next day. Looking at task manager it shows 6.27 gig used but looking at the processes list the totals don't show nearly that much. I am showing all processes from all users. I have also looked at the processes with PRocess Explorer and see the same results. Using resource monitor I see 4165 MB in Use, 2328 MB Modified and 1352MB Standby with only about 345 MB free. These numbers don't seem to add up to what I have running. I have Visual Studio 2010 running along with a number of IE8 sessions. I have run the same set of apps with XP SP2 32 bit with 4 gig of memory and never had this sort of problem. What is Modified memory? What is Standby memory? Any suggestions on what might be the issue and what might be a fix? TIA J

  • Always maximize almost maximized window utility

    - by AbstractDissonance
    It drives me nuts when a window is nearly maximized but not quite and when I go to close/move/scroll it I end up bringing up the window behind it. This happens all the time with acrobat. It seems that it's default non-minimized state is usually an "almost" maximized windowed. Is there any utility that will maximize a window when it is open or size changed when it is near the size of the monitor. I'll never have any need to have a window 99% the size of the window with it centered. Why? Because it behaves just as a maximized window by obscuring all(well, almost all) the windows behind it. (It should be only the main window of an application that is affected) The issue seems to be a few programs like acrobat that, I guess, try to fit it's contents which, sometimes, happens to be almost the full screen but not quite making it look maximized when it is not. I do not want all windows to open maximized but have no need for the window state almost centered and almost the same size as the desktop. (I imagine most people don't)

  • trying to setup multiple primary partitions on ubuntu linux [migrated]

    - by JohnMerlino
    I currently have ubuntu desktop installed on a harddrive. I want to partition the harddrive so that I can reserve 30 gigs for ubuntu server and 30 gigs for ubuntu desktop. The drive has 300 gigs available. Right now I am booting from dvd drive and installing ubuntu server. I selected "Guided partitioning" and created a 30 gig primary partition of Ext4 journaling filesystem, set "yes, format it" for format partition and set bootable flag to on. I intend to use this 30 gig partition to hold ubuntu server and allow me to boot from it. Now I have two other partitions. They are both set to "logical", one is currently using 285.8 gigs and is using ext4 (when I try to set bootable flag to true, it gives a warning "You are trying to set the bootable flag on a logical partition. The bootable flag is only useful on the primary partitions"). More alarming it says "No existing file system was detected in this partition". Actually, Im thinking that this is the parittion that is supposed to be holding my current Ubuntu Desktop. And of course I want this to be bootable and be a primary partition, so I could dual boot from this and the server partition. Now the third partition is also set to logical and it is being used as swap area. My question is regarding that second partition. Its supposed to be a primary partition thats holding my existing ubuntu desktop edition. How do I switch it to primary and to make sure that its pointing to my existing desktop installation?

  • Nagios: turn off service checks/display on down hosts

    - by Alien Life Form
    I want to to tweak nagios in such a way that all checking stops (with services not displayed, or displayed as unknown) for any down node. Said differently I only want to see one alert for a down host instead of 1 (down) + n (1 for every service). Note that I am interested in service display/status, not only in turning off notifications. Rationale: we use the nagios firefox/chrome plugin to monitor status and nagios' behavior is too noisy giving readings like these (because every node has 20 services): 3 down, 1 unreachable, 4 warnings, 87 critical This means that the 7 critical services on up node (the problem is on the service) are swamped in a slab of red services which are critical only because they sit on a node that's down/unreachable. What I'd rather like to see is: 3 down, 1 unreachable, 80 unknown, 4 warnings, 7 critical Or even 3 down, 1 unreachable, 4 warnings, 7 critical I have looked in service dependencies but I did not fine a way to describe: "make all services on a alive-host dependen on the status of the host check". I found the problem discussed here, where one of the participants thought it was a nagios bug, and here where one of the participants thought it was "as designed". As things are, I am just interested in the effect, much less in the design philosophy. Note that this nagios is checking hundreds of nodes, so the maintainablilty of the solution is also important. TIA and cheers.

  • Computer will freeze/ lock up after doing relatively stressful things

    - by GrowingCode247
    I'll first start off by saying that the issue GENERALLY doesn't occur unless I'm doing something remotely stressful for my computer. This issue used to occur whenever it felt it was necessary, however has not occurred completely randomly for a while now (thankfully) My computer's specs: CPU: AMD Phenom II X4 960T GPU: GeForce GTX 760 Memory: 16 GB RAM Resolution Used: 1680x1050, 59Hz (strange number for refresh rate?) res is highest for monitor Nvidia Driver version: 331.65 OS: Microsoft Windows 7 Ultimate (64-bit) Sometimes I will be able to go 2-3 games (about an hour, depending) and sometimes it will go maybe one game (20-30 minutes) and then my computer will run sluggishly and leave me unable to do much of anything. I can sometimes interact with programs at a very basic level (maximizing, minimizing), and I usually cannot close them in any way, not even through Task Manager. The highest temperature my GPU reaches is 76C, with the average being around 73C. During the time the temperatures are around 73C, my GPU's RAM usage is anywhere between 1250-1300 (out of 2GB). My CPU's temperature never goes over 60C, thankfully. The PSU should be fine. It's very mildly dusty but I feel as though that would not be causing this problem... I will clean it out as soon as everything else has been ruled out. Honestly I have no clue how to test the PSU for problems - same goes for my Motherboard. I cannot really think of what could be causing these freezes otherwise. Event Viewer details: EventID: 1 - VDS Basic Provider (I've no clue what this is) EventID: 3 - Kernel-EventTracing (Again, lost) EventID: 8003 - bowser (this seems fishy) and the one critical that I know others have been dealing with as I've browsed some other responses on the web: EventID: 41 - Kernel-Power any help to solve this problem would be GREATLY appreciated.

  • Server periodically freezing - Help Stabilizing

    - by JonDog
    We run an asp.net/sql server data collection website with a hand full of clients dumping data in and running reports. We moved to a new server (specs below) and have had issues with it freezing and having to reboot it a dozen times over the pass six months. The hosting company has mentioned possible causes (listed below) but cant give a definite answer on what is going wrong. They have offered to reconfigure how ever I like. We have benefited from having a much faster system and really dont want to get rid of the ssd's unless they are the issue. Two possible setup changes that I've talked with them about are also listed below. Any suggestions on what maybe causing the freezing issue as well as suggestion on a new setup would be great. My main questions are: Do SSD generally have problems running the OS & SQL Server on the same RAID Array? and Are the new SSD's still unrefined enough to be running in a production environment?

  • LDAPS being redirected to 389

    - by Ikkoras
    We're trying to perform an LDAPS bind to a server which blocks 389 with a firewall so all traffic must travel over 636. In our test lab we're connecting to a test ldap (located on the same server) which does not have this firewall so both ports are exposed. Running ldp.exe on the test server we generate the trace below which seems to suggest that it is successfully binding over 636. However if we monitor the traffic with wireshark all the traffic is being sent to 389 with no attempt to even contact 636. Other tools will bind only with SSL on 636 or without SSL on 389 whjich seems to suggest it is behaving correctly but Wireshark shows 389. Only the test server we are using RawCap to capture the local loopback traffic. Any ideas? 0x0 = ldap_unbind(ld); ld = ldap_sslinit("WIN-GF49504Q77T.test.com", 636, 1); Error 0 = ldap_set_option(hLdap, LDAP_OPT_PROTOCOL_VERSION, 3); Error 0 = ldap_connect(hLdap, NULL); Error 0 = ldap_get_option(hLdap,LDAP_OPT_SSL,(void*)&lv); Host supports SSL, SSL cipher strength = 128 bits Established connection to WIN-GF49504Q77T.test.com.

  • 1 PC, 2 consoles (as in 2 monitors, keyboards and mice)

    - by ciuly
    I have this desire to "kill 2 birds with one shot". Currently, I have 1 server running round the clock, 1 laptop that runs about 8 hours a day, 7 days a week, and a desktop that runs about the same length of time. All 3 are ... old, to say the least. So there is a great need to upgrade (well, the server might handle its job for another year or so, but that only depends on how much time I have to put it to "work"). Now, I'm "dreaming" of only one PC. I'm thinking vmware's ESX. So there will be a VM for the server, a VM for the "laptop" and one for the "desktop". And obviously I'll have to somehow "link" a set of monitor/keyboard/mouse with one of the laptop/desktop VMs. The server doesn't need such things, obviously (it doesn't have them at this moment either). Is something like this possible? ESX is not a requirement, it's just something I found that answers part of my problems, but there still remains the 2 KVM set that needs connecting and "linking" to appropriate VM. Why I would want to do this? well, first of all, it's much cheaper to upgrade one PC than 3. Then, the power consumption is obviously lower. Plus the extra space.Plus it allows me to better separate networks and services. Thanks.

  • How to prevent response to who-has requests on virtual eth interface?

    - by user42881
    Hi, we use small embedded X86 linux servers equipped with a single physical ethernet port as a gateway for an IP video surveillance application. Each downstream IP cam is mapped to a separate virtual IP address like this: real eth0 IP address= 192.168.1.1, camera 1 (eth0:1) =192.168.1.61, camera 2 (eth0:2) =192.168.1.62, etc. etc. all on the same eth0 physical port. This approach works well, except that a specific third-party windows video recording application running on a separate PC on the same LAN, automatically pings the virtual IPs looking for unique who-has responses on system startup and, when it gets back the same eth0 MAC address for each virtual interface, freaks out and won't allow us to subsequently manually enter those addresses. The windows app doesn't mind, tho, if it receives no answer to the who-has ping. My question - how can we either (a) shut off the who-has responses just for the virtual eth0:x interfaces while keeping them for the primary physical eth0 port, or, in the alternative, spoof a valid but different MAC address for each virtual interface? Thanks!

  • mysqld - master to slave replication using rsync innodb, sequence number issues

    - by Luis
    I've read several of the related topics posted here, but I have not been able to avoid this innodb error. The steps I've taken to replicate data from a Slackware server - 5.5.27-log (S) to a FreeBSD slave - 5.5.21-log (F) were these: (S) flush tables with read lock; (S) in another terminal show master status; (S) stop mysqld via command line in third terminal; (F) while both servers are stopped, rsync mysql datadir from (S), excluding master.info, mysql-bin and relay-* files; (F) start mysqld (skip-slave) 121018 12:03:29 InnoDB: Error: page 7 log sequence number 456388912904 InnoDB: is in the future! Current system log sequence number 453905468629. InnoDB: Your database may be corrupt or you may have copied the InnoDB InnoDB: tablespace but not the InnoDB log files. See InnoDB: http://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html InnoDB: for more information. This kind of error happens for a lot of tables. I know I can use dump, but the database is large, ca. 70GB and the systems are slow (old), so would like to get this replication to work with data transfer. What should I try to solve this issue?
