  • Ram configuration 4x4 or 2x8?

    - by Carl B
    I am looking to upgrade my Ram to 16gigs and I am wondering if there is any distinct advantage of the way I do it. That being a 4x4 or 2x8 set up. In all my searching there have been a number of pros for each profile. I can find no benchmarck results for either setup as a compaison. So, if there are 2 profiles of the same speed, same voltage, same timing and same cas what would perform better or have a better over all benafit? A few examples from my search - a 4x4 set would lend a benafit in that if one stick failed, you only lose 25% of your Ram vs 50% in a 2x8 set up. a 2x8 set up would have less strain on the memory controler and motherboard. a 2x8 would generate less heat. a 2x8 set up is easier to over clock (not part of my need, but alot of the comparisons circled around the overclocability ease of the 2 stick set up). There is one outstanding benafit that I have found in at least the target company I have looked at and that is price. The 2x8 is nearly half the cost. My motherboard supports a max of 16 gigs and I have a 64 bit OS. Has anyone seen any performance comparisons or is 16 gb just 16 gb no matter how you slice it? And is there any merit to the above pros? Edit: as per the mobo specs - Main Memory • Supports four unbuffered DIMM of 1.5 Volt DDR3 800/1066/1333/1600*/1800*/2133* (OC) DRAM, 16GB Max

  • Mass-migrating from POP3 to Exchange 2010, how do I copy mailboxes?

    - by Erik P. Skaalerud
    I'm in the process of planning our migration from an internal hosted POP3-server (dovecot) to Exchange 2010. We're using Outlook 2003 for the moment, but will soon upgrade to Outlook 2010. The big problem is that we have about 50 computers here in our HQ, plus ~30 clients in branch offices (wich will get their Exchange migration later sometime). I'm the only IT personel, and having to go around and manually set up Outlook and copy over their PST contents is not a option I'm looking for. Some users have set outlook to keep messages for X number of days on the POP3 server, others have not. Using a POP3 connector to transfer over the mails is not a viable option. Here is what I've done so far: Created a transform for the Office 2003 administrative installation point Created a .PRF file to modify any existing e-mail account to switch over to Exchange (including the RPC-encrypt hotfix described in MSKB 2006508) Tested both transform and PRF, both works Created a test-OU and GPO containing the Office 2003 installation with transform applied, also works My big question is: How can I force Outlook to import any existing .PST into the new Exchange mailbox when the user starts up Outlook for the first time after the MST/PRF have been applied? Is this possible?

  • How do you enable webcam support in facebook for ubuntu 10.04?

    - by Jonathan
    I think I have finally arrived at an insolvable equation: Chromium v.7 + Ubuntu 10.04 + Sun Java 6 + Webcam + Facebook + Flash 10 = non-functional All of those items listed above are potential points of failure in this situation, and any help narrowing them down would be fantastic. I am simply trying to enable webcame support directly through Facebooks website. Forum searches and the usual googling turn up few posts related to this specific equation. Two of the major suggestions include: 1) Installing the Sun (I refuse to say oracle sob)-provided Java implementation instead of the OpenJDK normally installed in ubuntu. And yes, after installing it, I did update all my default supports to use the sun commands over the openjdk. 2) Somehow enabling Facebook as a permitted site to access my webcam using Flash settings. I have not been able to explore option 2 because I cannot find a way to adjust the Flash settings in chromium 7. Other factors that do not help include the fact that I am pretty sure facebook changes its webcam interface every 10 seconds just to keep troubleshooters and support personnel on their toes. If anyone has a OTP that informs us of the next shift in the app, a leak would be greatly appreciated! Cheers!

  • Ubuntu problem - monitor out of range

    - by Kelp
    Hello, I am using an external monitor for my laptop to run Ubuntu with. I just updated Ubuntu today, but when it is about to reach the Ubuntu login screen, then the monitor says "out of range." Now, Ubuntu boots up into the GUI if I unplug my monitor and use my laptop screen, but I prefer to use the external display. I have tried all of the suggestions from my search results in Google. I tried pressing Ctrl + Alt + +, but nothing happens. I tried pressing Ctrl + Alt + -, but nothing happens. I used Ctrl + Alt + F2 to get into a terminal to run the command: sudo dpkg-reconfigure xserver-xorg, but nothing happens. I believe there are supposed to be options to change the settings, but it does not even give me any. I tried to edit /etc/usplash.conf and /nano/etc/usplash.conf, but they do not exist. I did sudo apt-get update and sudo apt-get upgrade hoping that it would install drivers or something to help my situation, but they did not help. My monitor is a Westinghouse 22" LCD with resolution 1680x1050. It has been working for the past few months until I updated it today.

  • Synchronizing the SamAccountName Property using Windows Azure Active Directory Sync Tool

    - by pk.
    Using this official documentation as a guide, I would expect the SamAccountName property to sync from my on-premise AD to Office 365. I think that it used to do exactly that, but now it seems that it doesn't so much sync the attribute as it does create an entirely new, unlinked value and store it in Office 365. This has caused some minor issues for me (broken scripts, annoying permissions management, etc.) and may be part of a more major issue regarding ADFS authentication. On-Premise PS C:\Windows\system32> Get-ADUser jdoe -Properties SamAccountName | fl SamAccountName SamAccountName : jdoe Office 365 Sync'ed Objects PS C:\Windows\system32> Get-Mailbox jdoe | fl SamAccountName SamAccountName : $1A7H20-K1LCOJFFBHGS I understand how to work around this issue in my scripts -- there exists the ImmutableId property which can be mapped back to the on-premise GUID. As far as the issue I'm having with ADFS, I'm less certain how to proceed and if this is causing my issues. At this point I really would just like some verification that I'm not crazy and that this used to be sync'ed at some point in the past and that Office 365 broke it relatively recently. I also think that MS documentation should perhaps be updated to exclude SamAccountName from the list of synchronized properties on the page I linked.

  • Boot stuck at blinking cursor before GRUB - only works via BIOS boot menu

    - by delta1
    I have a new box running Debian Squeeze. Grub is installed on /dev/sda, but when booting up I just get a blinking cursor, before the Grub menu. I can only boot to grub successfully when I choose boot options (during post) and select that specific drive! I have made sure the correct drive is set to boot first in the BIOS. So Grub works, but the system won't boot to that drive automatically? Any ideas on what could cause this? Drives sda/b/c are all 2TB (sda runs the system with b/c as raid device md0) with the following partitions: $ cat /proc/partitions major minor #blocks name 8 0 1953514584 sda 8 1 977 sda1 8 2 9765625 sda2 8 3 6445313 sda3 8 4 1937302627 sda4 8 32 1953514584 sdc 8 16 1953514584 sdb 9 0 1953513424 md0 but # fdisk -l /dev/sda gives WARNING: GPT (GUID Partition Table) detected on '/dev/sda'!

  • Subdomain is preventing my search results from rising as expected in page rank

    - by culov
    My problem is that I have a site which has requires a dedicated page for every city I choose to support. Early on, I decided to use subdomains rather than a directly after my domain (ie i used la.truxmap.com rather than truxmap.com/la). I realize now that this was a major mistake because Google seems to treat la.truxmap.com as a completely different site as ny.truxmap.com. So for instance, if i search "la food truck map" my site will be near the top, however, if i search "nyc food truck map" im no where in sight because ny.truxmap.com wouldnt be very high in the page rank by itself, and it doesnt have the boost that it ought to be getting from the better known la.truxmap.com So a mistake I made a year ago is now haunting my page rank. I'd like to know what the most painless way of resolving my dilemma might be. I have received so much press at la.truxmap.com that I can't just kill the site, but could I re-direct all requests at la.truxmap.com to truxmap.com/la and do the same for all cities supported without trashing my current, satisfactory page rank results I'm getting from la.truxmap.com ?? EDIT I left out some critical information. I am using Google Apps to manage my domain (that is, to add the subdomains) and Google App Engine to host my site. Thus, Google Apps provides a simple mechanism to mask truxmap.appspot.com (the app engine domain) as la.truxmap.com, but I don't see how I can mask it as truxmap.com/la. If I can get this done, then I can just 301 redirect la.truxmap.com to truxmap.com/la as suggested below. Thanks so much!

  • System x3550 M2 stuck on system initializing after firmware upgrades

    - by itmanager223
    Hey guys so i have been having this major issue for the last few hours now. I have a system x 3550M2 server and i ran the UEFI and IMM firmware upgrades within windows server 2008 R2 x64. All upgrades went fine and i was told to reboot. I performed the reboot cleanly using the OS restart option. Upon restarting it showed the system initializing screen and it stayed there for a good hour. After that hour i figured it froze and so i powered down and power up again. Now i can not boot back up to even see the IBM splash screen or the OS... I have tried switching the Jumpers to go to the backup UEFI and backup IMM and no luck. I have also reset the CMOS power and i have pressed the reset button 3 times on the light path and no luck. There are no lights light on the light path to indicate anything is broken. The only thing i see on the light path is the number 0.5. Any ideas guys i am quite stumped with this problem. Thanks a lot, Dani Cela

  • PHP potential issues with compiling 5.3.8 extensions against RHEL 6 / CentOS 6 PHP 5.3.3 package

    - by user101203
    I'm working on getting a Red Hat 6 LAMP server going and while the PHP that comes with it has many extensions we use, it doesn't have all of them. To solve this, I was thinking about either compiling the PHP extensions which come in the ext folder of the downloadable source code of PHP 5.3.3 from php.net same as #1, but using the extensions from the latest PHP version (currently 5.3.8). Do #1 but manually decide which updates to backport from the latest version of the PHP extensions into the older version and then compile the backported result A drawback to #1 is that security and bug fixes come out which we wouldn't be able to take advantage of. A drawback to #3 is that it might be a lot of work Does anyone know what the drawbacks to #2 are? I don't want to go down that route if it might result in some unexpected negative outcomes. Also, are there any other drawbacks to the other options or a better way to go altogether? I want to use the PHP 5.3.3 which comes with the Linux distro because I don't want us to get to a place again where we are forced to upgrade to a new version of PHP to stay on top of security updates like from PHP 5.2.x to 5.3.x and there be backwards incompatible changes (this is the situation we're in now with PHP 5.2.x no longer being supported).

  • How to make Microsoft JVM work on Windows 7?

    - by rics
    I am struggling with the following problem. I cannot install MS JVM 3810 properly on Windows 7. When I start Interner Explorer 8 without starting any java 1.1 programs choosing Java custom settings under Internet options causes the crash of the browser. I have some Java 1.1 programs that work well in Internet Explorer 8 on Windows XP after the installation of MS JVM 3810. I know that it is not advised to use this old JVM but it is not a short-term option to port the programs in newer Java since it contains 3rd party components. Complete rewrite is a long-term plan. Strangely jview and appletviewer (jview /a) works from a console so the MS JVM 3810 is not completely busted just IE 8 does not like it. The problem with the appletviewer is that it cannot connect to the server even if both signed and unsigned content in Java custom settings have been set to Enable all. (Since Java custom settings was unreachable due to the crash the modifications - including My computer - were performed through the registry and pre-checked to behave correctly on Windows XP and Internet Explorer 8.) If jview was working then I could at least think of a workaround. Is there a way to configure MS JVM or jview properly on Windows 7? Another options would be: Checking Internet Explorer 9 Beta. Using virtualbox and Windows XP older IE in it. Delaying Windows 7 upgrade. ... Update Finally we have modified all the programs to work parallelly as applet and application as well. This way the programs can still be used from browser on older Windows versions. On Windows 7 the applications are started from the desktop. Installation to all user machine can easily be solved since they already have a large common application drive. The code update is fortunately only a few lines of modification: including a main method in the applet class. Furthermore instead of the starting html page a bat file is used to set the classpath before the startup with jview.

  • Throughput and why do ISPs sell too much bandwidth?

    - by jonescb
    I hope the question made sense how I worded it. :) I've been wondering, maximum theoretical bandwidth is measured as RWIN/RTT (Window size / round trip time) Source 1 and Souce 2 So if a major city only 100 miles away gives me a ping of 50ms, and I have the default 64kb TCP window size then my maximum throughput will be 12.5Mb/s. Everything further away would give me a higher ping and therefore a lower throughput. Is there any reason to buy something like FiOS with a 50Mb/s or greater connection? Will you ever be able to reach that kind of speed? I know you can increase the TCP window size to increase throughput, but it has to be at both ends which is a deal breaker because you can't control the server. I'm assuming other network protocols like UDP aren't quite as affected by latency as TCP is, but how much of overall network traffic does non-TCP make up vs TCP. Am I just misguided about how throughput works? But if the above is correct, then why should a consumer like me buy way more bandwidth than can be realistically used. Maybe the only reason is for downloading multiple things at once, or one thing from multiple servers/peers?

  • Batch-Remove Specific Text from Photo Descriptions

    - by David
    I've recently upgraded to iPhoto '11 (couldn't resist the pricing on the new app store) and as I'm adding more meta-data to my library and generally organizing things (places, faces, etc... I hadn't upgraded since '08) I've noticed something odd in my photos. Every photo in my library has a description (though many are short), but it would appear that somehow the description of one of the photos has been appended to many. I don't know if maybe I accidentally screwed up a batch change at some point in the past, or if the library upgrade somehow messed up, or what else may have happened. But what I need to do is fix these somehow. Now, manually editing is something of a daunting task. Within a library of 21,248 photos, 18,858 of them have this additional text. The one thing I do have going for me is that it's a specific string. If there's a way to "remove this string from everywhere in the library without removing the rest of any given description" then that would be perfect. Is there anything I can do like this? Maybe even manually editing a library file in a text editor? (Would that break anything else in iPhoto if its library was edited outside of the application, even while it's not running?) Does anybody have any ideas?

  • sudo or acl or setuid/setgid?

    - by Xavier Maillard
    for a reason I do not really understand, everyone wants sudo for all and everything. At work we even have as many entries as there are way to read a logfile (head/tail/cat/more, ...). I think, sudo is defeating here. I'd rather use a mix of setgid/setuid directories and add ACL here and there but I really need to know what are the best practices before starting up. Our servers have %admin, %production, %dba, %users -i.e many groups and many users. Each service (mysql, apache, ...) has its own way to install privileges but members of the %production group must be able to consult configuration file or even log files. There is still the solution to add them into the right groups (mysql...) and set the good permission. But I do not want to usermod all users, I do not want to modify standards permissions since it could change after each upgrade. On the other hand, setting acls and/or mixing setuid/setgid on directories is something I could easily do without "defacing" the standard distribution. What do you think about this ? Taking the mysql example, that would look like this: setfacl d:g:production:rx,d:other::---,g:production:rx,other::--- /var/log/mysql /etc/mysql Do you think this is good practise or should I definetely usermod -G mysql and play with standard permissions system ? Thank you

  • Tuning up a MySQL server

    - by NinjaCat
    I inherited a mysql server, and so I've started with running the MySQLTuner.pl script. I am not a MySQL expert but I can see that there is definitely a mess here. I'm not looking to go after every single thing that needs fixing and tuning, but I do want to grab the major, low hanging fruit. Total Memory on the system is: 512MB. Yes, I know it's low, but it's what we have for the time being. Here's what the script had to say: General recommendations: Run OPTIMIZE TABLE to defragment tables for better performance MySQL started within last 24 hours - recommendations may be inaccurate Enable the slow query log to troubleshoot bad queries When making adjustments, make tmp_table_size/max_heap_table_size equal Reduce your SELECT DISTINCT queries without LIMIT clauses Increase table_cache gradually to avoid file descriptor limits Your applications are not closing MySQL connections properly Variables to adjust: query_cache_limit (> 1M, or use smaller result sets) tmp_table_size (> 16M) max_heap_table_size (> 16M) table_cache (> 64) innodb_buffer_pool_size (>= 326M) For the variables that it recommends that I adjust, I don't even see most of them in the mysql.cnf file.

  • How can I create a macro that acts on a relative reference rather than an absolute reference to cell A1?

    - by Bruce
    I have a master rent statement in an Excel 2007 (macro enabled) spreadsheet that shows all tenants in rows with columns formed by the months. Each tenant then has a separate rent statement sheet like the one below that pulls the data through from the master rent statement and all I do then is to copy the last 4 columns to the right and add them to the right, just renaming the month labelled as ‘rent due’ with the current month and then hiding the previous last 4 columns to the left so that the statement always shows the previous month's activity and the amount due for the current month: I used a macro to speed up the creation of these statements, but then found that in some cases the result was wrong and needed major correction because the macro use absolute references i.e. its starting position was relative to cell A1 whereas some of my rent worksheets commence from a different column and in some cases from a different column and a different row. I have tried recording the macro with 'Use relative references' but when trying to use the macro it only gets part way through its operation before it stops and the message appears: Run time error '1004' Application defined or object defined error with the option to End or Debug or go to Help and then I'm stuck as I don't know how to debug and work in VBA or understand what has gone wrong. I want to record a single macro that always remains relative to the last 'Total Due' column heading (in the sample, it’s cell FF3 but on another worksheet could be cell GA26) and thus enables me regardless of where on the worksheet the rent statement is placed to add through my recorded macro a further four columns with updated dates and a repositioned 'Total Due' summary (in the sample in cells FE23 and FF23). The contents of cells FE23 and FE22 are always the same number of rows from the 'Sample Rent Statement, Service Charge and Sub Total' rows. I've searched on the web and in the help files of Excel 2007 but have been totally stumped by this, so currently I have to re-record a quantity of macros each month to cover all of the permutations of the worksheets in my Excel rent workbook, which is starting to become pointless in terms of saving time. Does someone know a solution to this problem please?!

  • Limited user requires admin rights for plug and play printer?

    - by Kalamane
    I have a small fleet of laptops that aren't part of a domain running Windows XP Pro SP3 as limited users. They are used for printing different shipping documents. I have a script that runs when they start up that uses devcon and prntmngr to detect and install/configure the currently connected usb printers. This lets us deploy the laptops to any printing station with a USB printer and have the printer 'just work' for the end user employee. I've taken the original clone image and have added functionality to it. Since then I've discovered a bit of an issue with using HP LaserJet P1606dn printers. They have started asking for admin rights on setup. This is with and without the script running. Previously they would automatically install because I had installed WHQL plug and play drivers for them. I thought it might have to do with the HP Smart Install Utility but it happens when that is disabled. I don't have a good point to roll back to before this started happening because this was an issue on the image I took initially to start this upgrade. What could be causing this?

  • How to install (old) packages for Ubuntu 9.04?

    - by wchrisjohnson
    Based on some excellent feedback by Mark here (http://serverfault.com/questions/285598/should-i-clone-a-physical-server-to-create-a-vm-for-a-staging-server), today I was able to use the vmware converter to clone my production server for a staging server. However the nic won't come up no matter what I do. I attempted to inistall vmware tools, as I suspect that the fact that it is not installed might prevent the nic from working. (I have the nic set as a vmxnet3 card in the vm settings). The install failed because there were several dependencies missing as well as the Linux headers. Given that Ubuntu 9.04 has been EOL'd, the packages I need to install to get the vmware tools to install are no longer available. I doubt the ubuntu 9.04 install CD has the packages on it. What are my options? I'd rather not upgrade the version of Ubuntu yet, as the point of the vm right now is to maintain parity with the production server. Might I have better luck resetting the driver to use vmxnet2 instead of the vmxnet3? Thanks in advance! Chris

  • postfix email gateway

    - by k-h
    I am setting up a postfix email gateway. It will not hold any mail but will accept email for my domain and forward it to another internal mailserver and relay mail out from the internal server. One of the main problems is that I am working on a live running system and this will be an upgrade so I am using a test domain which I will change at some point to the real domain. I tried various methods but found the simplest way (that worked) was to use a script to create an aliases file (from ldap entries). There are various problems with this method. The main one being that the entries can't be of the simple form [email protected] because the gateway doesn't know where to send them. They have to be of the form: [email protected]. What I would like doesn't seem hard but I can't get my head around the postfix documentation. There seem to be various ways but none of them seem to work. Most of the examples I have found on the web assume the mail is going to end up on the server. I want a list of users somewhere, preferably of the form: user1, user2, etc rather than [email protected] (I can easily generate this list) and I would like postfix to forward all email to example.com to a particular server: ie realmailserver.example.com. Can anyone suggest clues as to how I might do this?

  • Servers - Buying New vs Buying Second-hand

    - by Django Reinhardt
    We're currently in the process of adding additional servers to our website. We have a pretty simple topology planned: A Firewall/Router Server infront of a Web Application Server and Database Server. Here's a simple (and technically incorrect) diagram that I used in a previous question to illustrate what I mean: We're now wondering about the specs of our two new machines (the Web App and Firewall servers) and whether we can get away with buying a couple of old servers. (Note: Both machines will be running Windows Server 2008 R2.) We're not too concerned about our Firewall/Router server as we're pretty sure it won't be taxed too heavily, but we are interested in our Web App server. I realise that answering this type of question is really difficult without a ton of specifics on users, bandwidth, concurrent sessions, etc, etc., so I just want to focus on the general wisdom on buying old versus new. I had originally specced a new Dell PowerEdge R300 (1U Rack) for our company. In short, because we're going to be caching as much data as possible, I focussed on Processor Speed and Memory: Quad-Core Intel Xeon X3323 2.5Ghz (2x3M Cache) 1333Mhz FSB 16GB DDR2 667Mhz But when I was looking for a cheap second-hand machine for our Firewall/Router, I came across several machines that made our engineer ask a very reasonable question: If we stuck a boat load of RAM in this thing, wouldn't it do for the Web App Server and save us a ton of money in the process? For example, what about a second-hand machine with the following specs: 2x Dual-Core AMD Opteron 2218 2.6Ghz (2MB Cache) 1000Mhz HT 16GB DDR2 667Mhz Would it really be comparable with the more expensive (new) server above? Our engineer postulated that the reason companies upgrade their servers to newer processors is often because they want to reduce their power costs, and that a 2.6Ghz processor was still a 2.6Ghz processor, no matter when it was made. Benchmarks on various sites don't really support this theory, but I was wondering what server admin thought. Thanks for any advice.

  • Is 1GB + 1GB RAM better than 2GB +0.5GB?

    - by pibboater
    My laptop has two slots for RAM, and currently has two 512 MB chips, for 1 GB. Windows XP is running terribly slow on it, so I want to upgrade the RAM. I could buy two 1 GB chips to replace both of the current 512 MB chips, to give me 2 GB of RAM. Or, the price is the same to buy one 2 GB chip, to replace just one of the 512 MB chips, and give me 2.5 GB total. The RAM it takes is PC2-4200 533MHz DDR2. What do you think would be better: buying two 1 GB chips so it can take advantage of dual-channel operation, or buying one 2 GB chip to end up with more total RAM but not dual-channel operation? Like I said, price is the same, so performance is the only consideration. I'm not doing anything especially intensive like video or photo editing -- just having multiple Office programs open, playing music, browsers, etc., but currently even opening the first application takes forever. If it matters, the laptop is a Toshiba Qosmio G25-AV513 running Windows XP Media Center SP3. Thanks! Kevin

  • php extensions & apache mods gone/not working after server restart?

    - by user1782359
    I was wondering if anyone has ever come across this before, as I'm pretty stumped to be honest, and my server admin knowledge isn't particular good so I'm not sure what could even be wrong, let alone how to fix it. Basically, Thursday last week everything was fine on our server. I come in on Friday and it's a mess: php extensions are missing/not working, apache modules are gone. (e.g. oci_* was gone completely, odbc_ not working but still there, the apache ntlm_auth for single sign on was gone and so the website wasn't even loading in IE). I'm ruling out anything deliberate because it's just incredibly unlikely. The only thing that really happened between thursday & friday is that on thursday evening one of the network guys did a RAM upgrade on the server and restarted it. That's it, nothing else. Now I'm wondering if somehow those extensions and such which we installed months ago were somehow only saved in a local memory of sorts, and a restart has wiped them? But we installed them all as root, so I don't see why it should be any different from installing anything else. It makes little/no sense to me. To expand on an example of something that's gone very wrong, the php odbc_ extension: It's still on the server, it doesn't return undefined function or anything. But it just cannot connect to the datasource any more. I've tested it through the command line and it's working perfectly fine with that datasource and login details, but all of a sudden having it in the php odbc_connect() function and it just can't connect. ( [S1000][unixODBC][FreeTDS][SQL Server]Unable to connect to data source. ) But unixODBC is set up fine. Like I say i've tested it all through the terminal and it can connect, and we've not changed anything, it's just now all of a sudden not working through the PHP function. Anyone have any ideas whatsoever as to what could be going on? This is on CentOS 5.x by the way.

  • iptables logging not working?

    - by vps_newcomer
    OS: Ubuntu 10.04 Logging daemon: rsyslog For some reason i'm not getting any iptables logs, even thought i don't look through them very often i'd still like to get it working for the sake of it working XD Here is my /etc/ryslog.d/iptables.conf :msg, contains, "[IPTABLES]" -/var/log/iptables.log & ~ My iptables logging prefix is "[IPTABLES]" followed by whatever else (example [IPTABLES] Denied xyz) the /var/log/iptables.log file is being created, however its not getting any entries. I can see the logging entries in dmesg but not in syslog or messages. Whats going on? EDIT: My iptables logging rules: # logging limit LoggingLimit=5/min LoggingPrefix=IPTABLES # Logging chain iptables -N LOG_REJECT iptables -A LOG_REJECT -j LOG # join INPUT to LOG_REJECT iptables -A INPUT -j LOG_REJECT # logging iptables -A LOG_REJECT -p tcp -m limit --limit $LoggingLimit -j LOG --log-prefix "$LoggingPrefix Denied TCP: " #--log-level 7 iptables -A LOG_REJECT -p udp -m limit --limit $LoggingLimit -j LOG --log-prefix "$LoggingPrefix Denied UDP: " #--log-level 7 iptables -A LOG_REJECT -p icmp -m limit --limit $LoggingLimit -j LOG --log-prefix "$LoggingPrefix Denied ICMP: " #--log-level 7 Update: I found a thread that has the same symptoms as i do, apparently is a kernel bug. I am using a VPS so could anyone point me on how to upgrade my kernel or apply a workaround? I couldn't find a 2.6.34 kernel listed in apt-cache.

  • HP DL380 G3 2U For Basic Web Server in 2012

    - by ryandlf
    I have an opportunity to pick up a used HP DL380 G3 2U for $100. I'm looking for a basic entry level web server that I can host a small - medium size website on and more or less learn the ins and outs of running my own web server before I bite the bullet and spend a couple grand on a server. The specs are: Dual (2) Intel Xeon 2.4GHz 400MHz 512KB Cache 4GB PC2100 ECC Registered Memory 6 x 72GB 10K U320 SCSI Hard Drives Smart Array 5i RAID Controller Redundant Power Supplies DVD/Floppy, Dual Intel GB NIC's, USB Or would I be better off spending a couple hundred bucks on something like: this new HP Seems like the only major difference is SATA and a bit of storage, but I will likely be implementing a separate storage system of some sort anyways. I guess it also wouldn't hurt to mention that I plan on running a linux server distro, so would the hardware be likely to support linux with a system that is 4 generations old? I don't mind spending a couple hundred extra dollars if its a better solution, but as mentioned previously I am simple looking for a server to learn on and probably use for a year or so while I put together a small - medium size website.

  • Installing Windows 8 to another computer with an OEM product Key

    - by user180671
    Questions come up after reading the article about the new method Microsoft uses to License windows 8 computers. Let say I bought a Brand new laptop with windows 8 preloaded. Not like the old way, there is no OEM sticker in the back of the computer which can be used for reloading system.(new product key is stored in BIOS as mentioned in the article, the key can be pulled out by using a software anyway). Is it possible to install windows 8 on another computer with that particular key in case the computer is totally damaged? Here is what i tried: First, I extracted the key with a software name "windows 8 key viewer". using the windows 8 upgrade tool to determine what copy of windows 8 I should download for the installation. The tool did correctly recognized the key as a legitimate one. but it claims that key can not be installed with a retail media (Since it is an oem key). Does this mean the only way to do it is to use an OEM CD from the manufacturer? Will ISO from MSDN source do? or it is just not possible??
