  • How to bridge Debian guest VM to VPN via Cisco AnyConnect Client running on Windows Vista host

    - by bgoodr
    I am running Cisco Anyconnect VPN Client version 2.5.3054 on a laptop running Windows Vista Home Premium (version 6.0.6002) Service Pack 2. I am running the VMware Player version 4.0.2 build-591240. The host operating system running under VMware Player is Debian 6.0.2.1 i386. The laptop is connected to a wireless connection, and I can browse the web from Windows Vista using Firefox just fine. I am able to boot into the Debian VM and open up a browser and access websites on the WAN from within the VM just fine. I can ping real Linux hosts on my LAN via: ping <lan_system>.local where <lan_system> is the hostname returned from uname -a on that system on my LAN. From a DOS CMD shell, I am able to ping hosts that exist on the remote network served by the Cisco AnyConnect Client's VPN network (and without the .local suffix applied as above): ping <remote_system> However, from within the Debian VM, I expect to be able to also ping those same remote hosts (<remote_system>) that are tunnelled over the VPN set up by Cisco AnyConnect Client. Let's say that I can ping a <remote_system> called flubber from a DOS CMD prompt just fine. When I execute Linux ping command from inside the Debian VM via: ping flubber It returns immediately with this output: ping: unknown host flubber For reference since I suspect it will be useful, here is the output of the route print command from the DOS CMD prompt: route print =========================================================================== Interface List 30 ...00 05 9a 3c 7a 00 ......

  • Is there really a need for encryption to have true wireless security? [closed]

    - by Cawas
    I welcome better key-wording here, both on tags and title. I'm trying to conceive a free, open and secure network environment that would work anywhere, from big enterprises to small home networks of just 1 machine. I think since wireless Access Points are the most, if not only, true weak point of a Local Area Network (let's not consider every other security aspect of having internet) there would be basically two points to consider here: Having an open AP for anyone to use the internet through Leaving the whole LAN also open for guests to be able to easily read (only) files on it, and even a place to drop files on Considering these two aspects, once everything is done properly... What's the most secure option between having that, or having just an encrypted password-protected wifi? Of course "both" would seem "more secure". But it shouldn't actually be anything substantial. That's the question, but I think it may need more elaborating on. If you don't think so, please feel free to skip the next (long) part. Elaborating more on the two aspects ... I've always had the feeling using any kind of the so called "wireless security" methods is actually a bad design. I'm talking mostly about encrypting and pass-phrasing (which are actually two different concepts), since I won't even consider hiding SSID and mac filtering. I understand it's a natural way of thinking. With cable networking nobody can access the network unless they have access to the physical cable, so you're "secure" in the physical way. In a way, encrypting is for wireless what building walls is for the cables. And giving pass-phrases would be adding a door with a key. But the cabling without encryption is also insecure. If someone plugin all the data is right there. So, while I can see the use for encrypting data, I don't think it's a security measure in wireless networks. It's wasting resources for too little gain. I believe we should encrypt only sensitive data regardless of wires. That's already done with HTTPS, so I don't really need to encrypt my torrents, for instance. They're torrents, they are meant to be freely shared! As for using passwords, they should be added to the users, always. Not to wifi. For securing files, truly, best solution is backup. Sure all that doesn't happen that often, but I won't consider the most situations where people just don't care. I think there are enough situations where we actually use passwords on our OS users, so let's go with that in mind. I keep promoting the Fonera concept as an instance. It opens up a free wifi port, if you choose so, and anyone can connect to the internet through that, without having any access to your LAN. It also uses a QoS which will never let your bandwidth drop from that public usage. That's security, and it's open. But it's lacking the second aspect. I'll probably be bashed for promoting the non-usage of WPA 2 with AES or whatever, but I wanted to know from more experienced (super) users out there: what do you think?

  • Distinction between Cloud Servers and VPS

    - by Frank V
    What is the distinction between a Cloud based host and a VPS? I talked to a Rackspace Cloud sales person for around 45 minutes and never came to a real conclusion on this. So, to elaborate on my question a bit -- what benefits might a "cloud" server provide me versus a VPS provider such as Linode and vice versa -- what benefits would a VPS provide over a cloud provider? From what I've been able to ascertain, when you host on a cloud (with Rackspace Cloud) you get a instance of Linux in which you install software and such (a LAMP, for instance). From what I can figure, if the instance is running, I am charged and the pricing on Rackspace (according to what I understood from the sales rep) comes out to about $20 a month.... I was thinking a cloud customer pays per processing hours -- so if your app just sits there, no charges are incurred. Does one not pay of the cloud instance is shut down, perhaps? A similar questions to what I'm asking but not exactly it: Understanding: cloud-server, cloud-hosting, cloud-computing, the cloud What is the difference between vps and cloud hosting

  • xen debian: domU can't get out side

    - by iftol
    hi every body. i'm a trainee as a sysAdmin, it is my first expérience with virtualization. i have a server setup debian xen 3 with 2 physical interfaces. eth 0 for local network 10.0.0.1 and eth1 for internet (194.X.X.4). i created 3 VMs (web server, mail server and dabase server) with local ip addresses 172.10.0.x/24. the problem i had first is that domU can't ping dom0. i asked the sysAdmin of our ISP and he sais that he fogot to setup the bridginb. so he ceated a bridge with 172.10.0.1/24 after that i was able to ping the real server (194.X.X.4). but i can't go out side from my VMs, how can i fixe this issue? real or physical server ifconfig eth0 Link encap:Ethernet HWaddr 23:26:34:84:ce:xe inet adr:10.1.3.12 Bcast:10.1.3.255 Masque:255.255.255.0 adr inet6: fe80::226:b9ff:fe84:ceb4/64 Scope:Lien UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:412006 errors:0 dropped:0 overruns:0 frame:0 TX packets:411296 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 RX bytes:31410957 (29.9 MiB) TX bytes:31178370 (29.7 MiB) Interruption:36 Mémoire:d6000000-d6012100 eth1 Link encap:Ethernet HWaddr 23:26:34:84:ce:xe inet adr:194.x.x.4 Bcast:194.254.167.255 Masque:255.255.255.0 adr inet6: fe80::226:b9ff:fe84:ceb6/64 Scope:Lien UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:25872332 errors:0 dropped:0 overruns:0 frame:0 TX packets:414578 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:0 RX bytes:2642278343 (2.4 GiB) TX bytes:35436775 (33.7 MiB) lo Link encap:Boucle locale inet adr:127.0.0.1 Masque:255.0.0.0 adr inet6: ::1/128 Scope:Hôte UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1308073 errors:0 dropped:0 overruns:0 frame:0 TX packets:1308073 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:0 RX bytes:109871395 (104.7 MiB) TX bytes:109871395 (104.7 MiB) peth1 Link encap:Ethernet HWaddr 23:26:34:84:ce:xe UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:31818694 errors:0 dropped:0 overruns:0 frame:0 TX packets:414818 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 RX bytes:5197318822 (4.8 GiB) TX bytes:37904897 (36.1 MiB) Interruption:48 Mémoire:d8000000-d8012100 vif281.0 Link encap:Ethernet HWaddr fe:ff:ff:ff:ff:ff adr inet6: fe80::fcff:ffff:feff:ffff/64 Scope:Lien UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:207 errors:0 dropped:0 overruns:0 frame:0 TX packets:298 errors:0 dropped:2 overruns:0 carrier:0 collisions:0 lg file transmission:32 RX bytes:24629 (24.0 KiB) TX bytes:28404 (27.7 KiB) vif281.1 Link encap:Ethernet HWaddr fe:ff:ff:ff:ff:ff adr inet6: fe80::fcff:ffff:feff:ffff/64 Scope:Lien UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:45 errors:0 dropped:47063 overruns:0 carrier:0 collisions:0 lg file transmission:32 RX bytes:0 (0.0 B) TX bytes:4449 (4.3 KiB) vif282.0 Link encap:Ethernet HWaddr fe:ff:ff:ff:ff:ff adr inet6: fe80::fcff:ffff:feff:ffff/64 Scope:Lien UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:78 errors:0 dropped:0 overruns:0 frame:0 TX packets:13 errors:0 dropped:1 overruns:0 carrier:0 collisions:0 lg file transmission:32 RX bytes:5041 (4.9 KiB) TX bytes:714 (714.0 B) xenbr0 Link encap:Ethernet HWaddr fe:ff:ff:ff:ff:ff inet adr:172.10.0.1 Bcast:172.10.0.255 Masque:255.255.255.0 adr inet6: fe80::5c72:c6ff:fe49:7fe/64 Scope:Lien UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7180 errors:0 dropped:0 overruns:0 frame:0 TX packets:8615 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:0 RX bytes:756804 (739.0 KiB) TX bytes:791206 (772.6 KiB) brtcl show bridge name bridge id STP enabled interfaces eth1 8000.0026b984ceb6 no peth1 vif281.1 xenbr0 8000.feffffffffff no vif281.0 vif282.0 network-multi-bridge /etc/xen/scripts/network-virtual start vifnum="0" bridgeip="172.10.0.1/24" brnet="172.10.0.0/24" VM webserver eth0 Link encap:Ethernet HWaddr 00:16:3E:42:33:70 inet addr:172.10.0.2 Bcast:172.10.0.255 Mask:255.255.255.0 inet6 addr: fe80::216:3eff:fe42:3370/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3 errors:0 dropped:0 overruns:0 frame:0 TX packets:27 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:126 (126.0 b) TX bytes:2036 (1.9 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Thank you for your help.

  • Custom SNMP Cacti Data Source fails to update

    - by Andrew Wilkinson
    I'm trying to create a custom SNMP datasource for Cacti but despite everything I can check being correct, it is not creating the rrd file, or updating it even when I create it. Other, standard SNMP sources are working correctly so it's not SNMP or permissions that are the problem. I've created a new Data Query, which when I click on "Verbose Query" on the device screen returns the following: + Running data query [10]. + Found type = '3' [SNMP Query]. + Found data query XML file at '/volume1/web/cacti/resource/snmp_queries/syno_volume_stats.xml' + XML file parsed ok. + missing in XML file, 'Index Count Changed' emulated by counting oid_index entries + Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.25.2.3.1.3' Index Count: 8 + Index found at OID: '.1.3.6.1.2.1.25.2.3.1.3.1' value: 'Physical memory' + Index found at OID: '.1.3.6.1.2.1.25.2.3.1.3.3' value: 'Virtual memory' + Index found at OID: '.1.3.6.1.2.1.25.2.3.1.3.6' value: 'Memory buffers' + Index found at OID: '.1.3.6.1.2.1.25.2.3.1.3.7' value: 'Cached memory' + Index found at OID: '.1.3.6.1.2.1.25.2.3.1.3.10' value: 'Swap space' + Index found at OID: '.1.3.6.1.2.1.25.2.3.1.3.31' value: '/' + Index found at OID: '.1.3.6.1.2.1.25.2.3.1.3.32' value: '/volume1' + Index found at OID: '.1.3.6.1.2.1.25.2.3.1.3.33' value: '/opt' + index_parse at OID: '.1.3.6.1.2.1.25.2.3.1.3.1' results: '1' + index_parse at OID: '.1.3.6.1.2.1.25.2.3.1.3.3' results: '3' + index_parse at OID: '.1.3.6.1.2.1.25.2.3.1.3.6' results: '6' + index_parse at OID: '.1.3.6.1.2.1.25.2.3.1.3.7' results: '7' + index_parse at OID: '.1.3.6.1.2.1.25.2.3.1.3.10' results: '10' + index_parse at OID: '.1.3.6.1.2.1.25.2.3.1.3.31' results: '31' + index_parse at OID: '.1.3.6.1.2.1.25.2.3.1.3.32' results: '32' + index_parse at OID: '.1.3.6.1.2.1.25.2.3.1.3.33' results: '33' + Located input field 'index' [walk] + Executing SNMP walk for data @ '.1.3.6.1.2.1.25.2.3.1.3' + Found item [index='Physical memory'] index: 1 [from value] + Found item [index='Virtual memory'] index: 3 [from value] + Found item [index='Memory buffers'] index: 6 [from value] + Found item [index='Cached memory'] index: 7 [from value] + Found item [index='Swap space'] index: 10 [from value] + Found item [index='/'] index: 31 [from value] + Found item [index='/volume1'] index: 32 [from value] + Found item [index='/opt'] index: 33 [from value] + Located input field 'volsizeunit' [walk] + Executing SNMP walk for data @ '.1.3.6.1.2.1.25.2.3.1.4' + Found item [volsizeunit='1024 Bytes'] index: 1 [from value] + Found item [volsizeunit='1024 Bytes'] index: 3 [from value] + Found item [volsizeunit='1024 Bytes'] index: 6 [from value] + Found item [volsizeunit='1024 Bytes'] index: 7 [from value] + Found item [volsizeunit='1024 Bytes'] index: 10 [from value] + Found item [volsizeunit='4096 Bytes'] index: 31 [from value] + Found item [volsizeunit='4096 Bytes'] index: 32 [from value] + Found item [volsizeunit='4096 Bytes'] index: 33 [from value] + Located input field 'volsize' [walk] + Executing SNMP walk for data @ '.1.3.6.1.2.1.25.2.3.1.5' + Found item [volsize='1034712'] index: 1 [from value] + Found item [volsize='3131792'] index: 3 [from value] + Found item [volsize='1034712'] index: 6 [from value] + Found item [volsize='775904'] index: 7 [from value] + Found item [volsize='2097080'] index: 10 [from value] + Found item [volsize='612766'] index: 31 [from value] + Found item [volsize='1439812394'] index: 32 [from value] + Found item [volsize='1439812394'] index: 33 [from value] + Located input field 'volused' [walk] + Executing SNMP walk for data @ '.1.3.6.1.2.1.25.2.3.1.6' + Found item [volused='1022520'] index: 1 [from value] + Found item [volused='1024096'] index: 3 [from value] + Found item [volused='32408'] index: 6 [from value] + Found item [volused='775904'] index: 7 [from value] + Found item [volused='1576'] index: 10 [from value] + Found item [volused='148070'] index: 31 [from value] + Found item [volused='682377865'] index: 32 [from value] + Found item [volused='682377865'] index: 33 [from value] AS you can see it appears to be returning the correct data. I've also set up data templates and graph templates to display the data. The create graphs for a device screen shows the correct data, and when selecting one row can clicking create a new data source and graph are created. Unfortunately the data source is never updated. Increasing the poller log level shows that it appears to not even be querying the data source, despite it being used? What should my next steps to debug this issue be?

  • Socket 1155 vs 2011 vs Haswell

    - by woody
    The title says it all. I am trying to decide between sockets and just cant pinpoint which to get based on pros and cons. The build this will go into will be my primary PC. It will be used for every day computing, coding, some multimedia and gaming. I have read that 1155 and 2011 will be dead within the new year and that Haswell will double the performance of Ivy Bridge. What is a general run down on the different sockets? Pros and Cons? More specifically what are the technical differences between the three?

  • Is the Cloud ready for an Enterprise Java web application? Seeking a JEE hosting advice.

    - by Jakub Holý
    Greetings to all the smart people around here! I'd like to ask whether it is feasible or a good idea at all to deploy a Java enterprise web application to a Cloud such as Amazon EC2. More exactly, I'm looking for infrastructure options for an application that shall handle few hundred users with long but neither CPU nor memory intensive sessions. I'm considering dedicated servers, virtual private servers (VPSs) and EC2. I've noticed that there is a project called JBoss Cloud so people are working on enabling such a deployment, on the other hand it doesn't seem to be mature yet and I'm not sure that the cloud is ready for this kind of applications, which differs from the typical cloud-based applications like Twitter. Would you recommend to deploy it to the cloud? What are the pros and cons? The application is a Java EE 5 web application whose main function is to enable users to compose their own customized Product by combining the available Parts. It uses stateless and stateful session beans and JPA for persistence of entities to a RDBMS and fetches information about Parts from the company's inventory system via a web service. Aside of external users it's used also by few internal ones, who are authenticated against the company's LDAP. The application should handle around 300-400 concurrent users building their product and should be reasonably scalable and available though these qualities are only of a medium importance at this stage. I've proposed an architecture consisting of a firewall (FW) and load balancer supporting sticky sessions and https (in the Cloud this would be replaced with EC2's Elastic Load Balancing service and FW on the app. servers, in a physical architecture the load-balancer would be a HW), then two physical clustered application servers combined with web servers (so that if one fails, a user doesn't loose his/her long built product) and finally a database server. The DB server would need a slave backup instance that can replace the master instance if it fails. This should provide reasonable availability and fault tolerance and provide good scalability as long as a single RDBMS can keep with the load, which should be OK for quite a while because most of the operations are done in the memory using a stateful bean and only occasionally stored or retrieved from the DB and the amount of data is low too. A problematic part could be the dependency on the remote inventory system webservice but with good caching of its outputs in the application it should be OK too. Unfortunately I've only vague idea of the system resources (memory size, number and speed of CPUs/cores) that such an "average Java EE application" for few hundred users needs. My rough and mostly unfounded estimate based on actual Amazon offerings is that 1.7GB and a single, 2-core "modern CPU" with speed around 2.5GHz (the High-CPU Medium Instance) should be sufficient for any of the two application servers (since we can handle higher load by provisioning more of them). Alternatively I would consider using the Large instance (64b, 7.5GB RAM, 2 cores at 1GHz) So my question is whether such a deployment to the cloud is technically and financially feasible or whether dedicated/VPS servers would be a better option and whether there are some real-world experiences with something similar. Thank you very much! /Jakub Holy PS: I've found the JBoss EAP in a Cloud Case Study that shows that it is possible to deploy a real-world Java EE application to the EC2 cloud but unfortunately there're no details regarding topology, instance types, or anything :-(

  • How well will ntpd work when the latency is highly variable?

    - by JP Anderson
    I have an application where we are using some non-standard networking equipment (cannot be changed) that goes into a dormant state between traffic bursts. The network latency is very high for the first packet since it's essentially waking the system, waiting for it to reconnect, and then making the first round-trip. Subsequent messages (provided they are within the next minute or so) are much faster, but still highly-latent. A typical set of pings will look like 2500ms, 900ms, 880ms, 885ms, 900ms, 890ms, etc. Given that NTP uses several round trips before computing the offset, how well can I expect ntpd to work over this kind of link? Will the initially slow first round trip be ignored based on the much different (and faster) following messages to/from the ntp server? Thanks and Regards.

  • How much processor speed and cores do I need for these tasks?

    - by ajay
    I am planning to buy a new laptop as I find my current one very slow. My question here is specifically related to RAM size and CPU power. I will mostly be doing development (not much games). I would be dabbling in distributed computing, multithreaded and data intensive parallelizable tasks on multi-cores. For e.g. I would want to be able to Concurrent programming in Scala/Java/Clojure etc. and be able to see parallelization. Furthermore, I would want the RAM to be enough. But from a developer machine standpoint, do you think 4GB RAM and 2.53GHz Dual Core processor would be enough. I'm basically looking at this model: http://store.apple.com/us/configure/MC118LL/A?mco=MTM3NDcyODk (link dead)

  • How clean is deleting a computer object?

    - by Kevin
    Though quite skilled at software development, I'm a novice when it comes to Active Directory. I've noticed that AD seems to have a lot of stuff buried in the directory and schema which does not appear superficially when using simplified tools such as Active Directory Users and Computers. It kind of feels like the Windows registry, where COM classes have all kinds of intertwined references, many of which are purely by GUID, such that it's not enough to just search for anything referencing "GadgetXyz" by name in order to cleanly remove GadgetXyz. This occasionally leads to the uneasy feeling that I may have useless garbage building up in there which I have no idea how to weed out. For instance, I made the mistake a while back of trying to rename a DC, figuring I could just do it in the usual manner from Control Panel. I found references to the old name buried all over the place which made it impossible to reuse that name without considerable manual cleanup. Even long after I got it all working, I've stumbled upon the old name hidden away in LDAP. (There were no other DCs left in the picture at that time so I don't think it was a tombstone issue.) More specifically, I'm worried about the case of just outright deleting a computer from AD. I understand the cleanest way to do it is to log into the computer itself and tell it to leave the domain. (As an aside, doing this in Windows 8 seems to only disable the computer object and not delete it outright!) My concern is cases where this is not possible, for instance because it was on an already-deleted VM image. I can simply go into Active Directory Users and Computers, find the computer object, click it, and press Delete, and it seems to go away. My question is, is it totally, totally gone, or could this leave hanging references in any Active Directory nook or cranny I won't know to look in? (Excluding of course the expected tombstone records which expire after a set time.) If so, is there any good way to clean up the mess? Thank you for any insight! Kevin ps., It was over a year ago so I don't remember the exact details, but here's the gist of the DC renaming issue. I started with a single 2008 DC named ABC in a physical machine and wanted to end up instead with a DC of the same name running in a vSphere VM. Not wanting to mess with imaging the physical machine, my plan instead was: Rename ABC to XYZ. Fresh install 2008 on a VM, name it ABC, and join it to the domain. (I may have done the latter in the same step as promoting to DC; I don't recall.) dcpromo the new ABC as a 2nd DC, including GC. Make sure the new ABC replicated correctly from XYZ and then transfer the FSMO roles from XYZ to it. Once everything was confirmed to work with the new ABC alone, demote XYZ, remove the AD role, and remove it from the domain. Eventually I managed to do this but it was a much bumpier ride than expected. In particular, I got errors trying to join the new ABC to the domain. These included "The pre-windows 2000 name is already in use" and "No mapping between account names and security IDs was done." I eventually found that the computer object for XYZ had attributes that still referred to it as ABC. Among these were servicePrincipalName, msDS-AdditionalDnsHostName, and msDS-AdditionalSamAccountName. The latter I could not edit via Attribute Editor and instead had to run this against XYZ: NETDOM computername <simple-name> /add:<FQDN> There were some other hitches I don't remember exactly.

  • which NoSQL for billions of records [closed]

    - by airtruk
    There are plenty of discussions around NoSQL databases around and a lot of them are about data logging in the social media section. The problem I'm trying to solve falls more into the scientific computing section, where I have several 1000s of billions of pieces of information that I want to query with different a different criteria for each query. All data is at least a 4 dimensional space, which means I have a 3D location (x,y,z) and a time component - plus the value and unit. Say temperature at xyz and 10min in degree Celcius. A typical query result may contain several million results ... I have read about pretty much all NoSQL solutions being exceptionally fast for inserting records, but when it comes to querying them it's a different story. I'm leaning towards MongoDB for the implementation and platform for developing the necessary code since it is more closely related to the current solution using MySQL. Happy to be proven wrong though when it comes to the choice of the NoSQL solution.

  • httperrors for Linux

    - by Aaron McRuer
    I'm here because the Google has failed to get me what I need. I just recently graduated from university, and I'm working on a website. Back in college I used the school's web server for my projects, and there were a few tools that aided in the process. One was a Linux program/script/executable/prayer to the computing gods called "httperrors". You typed that into bash, and it would pop up any errors that would occur while running the web server. Specifically, if you had errors in your php code, it would tell you what was wrong. I guess it was a debugger of sorts. I can't find any such program's details online. Does this sound familiar to anyone?

  • How could I represent 1.625 by 0 or a 1 (binary digit)?

    - by pepito
    This is an excerpt from wikipedia about 'full rate' speech coding standard. Full Rate or FR or GSM-FR or GSM 06.10 was the first digital speech coding standard used in the GSM digital mobile phone system. The bit rate of the codec is 13 kbit/s, or 1.625 bits/audio sample. And this one is an excerpt from wikipedia about bit. In computing parlance, bit is the abbreviation for a single binary digit, represented by a 0 or a 1. How could I represent 1.625 by 0 or a 1? Actually, that's my lecturer's question that I could not answer. Some links to papers are more than welcome. Thanks in advance.

  • What kind of server do I need to handle 10 million requests and mySQL queries a day?

    - by Calvin
    I'm a new bie of server administration and I'm looking for a powerful hosting service to host my new website. This website is basically a back-end of an mobile online game, and it will: handle up to 10 million of HTTPS request and mySQL queries a day store up to 2000 GB file on the hard disk transfer probably 5000 GB data in and out per month it runs on PHP and mySQL have 10 million records in mySQL database, for each record there are 5-10 fields, around 100 bytes each I really don't know what kind of a server I need to handle these requirements, my question is: what cpu/ram do I need for a dedicated server or vps? what hosting companies are able to offer this kind of dedicated server or VPS? what about cloud computing? I've researched Amazon EC2 but it seems complicated to me. And I've contacted Rackspace but strangely they said Cloudsites is not suitable for my requirements. I wonder if there is other cloud hosting company. any other alternative method? thanks very much!

  • Since upgrading to Solaris 11, my ARC size has consistently targeted 119MB, despite having 30GB RAM. What? Why?

    - by growse
    I ran a NAS/SAN box on Solaris 11 Express before Solaris 11 was released. The box is an HP X1600 with an attached D2700. In all, 12x 1TB 7200 SATA disks, 12x 300GB 10k SAS disks in separate zpools. Total RAM is 30GB. Services provided are CIFS, NFS and iSCSI. All was well, and I had a ZFS memory usage graph looking like this: A fairly healthy Arc size of around 23GB - making use of the available memory for caching. However, I then upgraded to Solaris 11 when that came out. Now, my graph looks like this: Partial output of arc_summary.pl is: System Memory: Physical RAM: 30701 MB Free Memory : 26719 MB LotsFree: 479 MB ZFS Tunables (/etc/system): ARC Size: Current Size: 915 MB (arcsize) Target Size (Adaptive): 119 MB (c) Min Size (Hard Limit): 64 MB (zfs_arc_min) Max Size (Hard Limit): 29677 MB (zfs_arc_max) It's targetting 119MB while sitting at 915MB. It's got 30GB to play with. Why? Did they change something? Edit To clarify, arc_summary.pl is Ben Rockwood's, and the relevent lines generating the above stats are: my $mru_size = ${Kstat}->{zfs}->{0}->{arcstats}->{p}; my $target_size = ${Kstat}->{zfs}->{0}->{arcstats}->{c}; my $arc_min_size = ${Kstat}->{zfs}->{0}->{arcstats}->{c_min}; my $arc_max_size = ${Kstat}->{zfs}->{0}->{arcstats}->{c_max}; my $arc_size = ${Kstat}->{zfs}->{0}->{arcstats}->{size}; The Kstat entries are there, I'm just getting odd values out of them. Edit 2 I've just re-measured the arc size with arc_summary.pl - I've verified these numbers with kstat: System Memory: Physical RAM: 30701 MB Free Memory : 26697 MB LotsFree: 479 MB ZFS Tunables (/etc/system): ARC Size: Current Size: 744 MB (arcsize) Target Size (Adaptive): 119 MB (c) Min Size (Hard Limit): 64 MB (zfs_arc_min) Max Size (Hard Limit): 29677 MB (zfs_arc_max) The thing that strikes me is that the Target Size is 119MB. Looking at the graph, it's targeted the exact same value (124.91M according to cacti, 119M according to arc_summary.pl - think the difference is just 1024/1000 rounding issues) ever since Solaris 11 was installed. It looks like the kernel's making zero effort to shift the target size to anything different. The current size is fluctuating as the needs of the system (large) fight with the target size, and it appears equilibrium is between 700 and 1000MB. So the question is now a little more pointed - why is Solaris 11 hard setting my ARC target size to 119MB, and how do I change it? Should I raise the min size to see what happens? I've stuck the output of kstat -n arcstats over at http://pastebin.com/WHPimhfg Edit 3 Ok, weirdness now. I know flibflob mentioned that there was a patch to fix this. I haven't applied this patch yet (still sorting out internal support issues) and I've not applied any other software updates. Last thursday, the box crashed. As in, completely stopped responding to everything. When I rebooted it, it came back up fine, but here's what my graph now looks like. It seems to have fixed the problem. This is proper la la land stuff now. I've literally no idea what's going on. :(

  • Installing ethernet drivers with no install package

    - by Josh
    I recently got my new Sony Vaio laptop and formatted it into Windows 7 Ultimate. I would like to use the Windows Easy Transfer Tool over a network connection to transfer some of my files over from my desktop PC. Before I do this though, I need to install the ethernet LAN drivers (I'm currently using the built in Wifi). I downloaded the original LAN driver that came with my Vaio originally from the Sony website: http://support.vaio.sony.eu/computing/vaio/downloads/preinstalled/index.aspx?l=en_GB&m=VPCEB1Z0E_B [Scroll down to the 450KB Ethernet driver] When I unzip the package, these files are inside: yk62x64.cat yk62x64.dll yk62x64.inf yk62x64.sys As you can see, no installer. Can anyone guide me through how to properly install these drivers? I have thought of using Google but I'm clueless as to what query to use. Thanks.

  • Cheapest way to connect 20-24 Sata II HDDs in a budget storage server?

    - by Joe Hopfgartner
    I need to assemble a high density storage server for as cheap as possible. It's been a while for me and the last systems I integrated didn't even have Sata yet... During my Research I of course stumbled about Nexsan SATA Beast, the BackBlaze storage Pods as well as some ridiculously overpriced HP Proliant or Dell storage solutions. Finally I choose Norco cases as the way to go. My eye is set on the RPC-4020, which is a 4U 19" Rackmount case with 20 Hot Swap 3.5" SATA/SAS Hdd trays (Backplanes included) and room for two 2.5" OS drives as well as a Slim Line CD-Rom. The backplanes connect with a single SATA port for each drive, so there are 20 internal SATA ports to to be connected. They also have redundant power ports which I think is quite nice. The cheapest price I have found is 290$ + 40$ shipping. In europe the cheapest unfortunately is 370€ (500$) + 40 € shipping... A nice alternative would be the RPC-4224 which has SFF-8087 Mini SAS connectors that bundle 4 SATA trays each. But it doesn't seem to be available in Europe (where i am) anywhere. So here comes my problem: What Mainboard/Controller to choose to connect them for as cheap as possible while still having nice data rates? I have to say that the server is intended as a Storage server with 1gps connectivity and the data transfer will be distributed very evenly across all drives. I also don't require any raid functionality. This is all done at application level, I just need JBOD. So for example if I go for the RPC 4020 Model I need to connect 20 Storage + 1 OS + 1 CDROM Sata ports. I searched a bit and stumbled across this very low priced controller: http://www.intel.com/products/server/raid-controllers/SASWT4I/SASWT4I-overview.htm They sell it for 115 € here and the specs say it can control up to 122 hard discs and has 4 Mini SAS connectors. So I would use 4 Mini SAS 36pin - 4 SATA 7pin cables to connect 4 SATA drives to each port and choose a Mainboard taht has 6 SATA on board (for example this one) and hurray, I can connect my 22 SATA devices for as low as about ~ 220 EUR (cpu, ram, psu, case not counted) Question: WOULD THAT WORK? And if not, why? 2nd Question: If I go for the 4220 or 4224 Model, I have internal Mini SAS connectors. Am I right in assuming that the backplane than acts as a "SAS Expander"? And can I just plug these SAS connectors into any SAS port I can find on my controller / mainboard or are there certain requirements? I know that SATA port multipliers only work with controllers that are ready for that. But isn't this expansion already implemented in the SAS standard? I am sorry that this is a very broad question, but I really spent the last week reading up and it seems to be not so clear! Especially all the controlling hardware specifications! 3rd Question: A lot of hardware specs feature "internal channels" and "internal connectors". The connecors are the physical numbers of places where I can plug a cable in. I got that. But are the "internal channels" always the maximum numbers of physical drives that can be used in the end? Or can I enhance this further by Expanders/Fanouts? 4th and last question: What do you think about the setup so far? Do you know any good alternatives? Maby I am completely going the wrong way and some DAS would be way better? Are there any comparable chassis available in europe? Please feel free to say whatever you think is relevant to the subject!

  • What's the difference between "Flash Drive" and "Flash Memory"?

    - by Clive D
    I have a problem with a Blu ray disk I bought. I talked to a Sony technician who advised me to plug a "USB Flash Memory Stick" into the Blu-ray player. Is this something specific? Is there a difference between the following two? "USB Flash Drive" "USB Flash Memory" When I go to Curry's or other sites that sell USB Sticks, they only talk about "USB Flash Drives". I've been in computing for many years and know the basics, but "memory" and "drive" are different things to me.

  • How do I give MacPorts privileges?

    - by cojadate
    I tried to install PostgreSQL server development libraries using MacPorts and got the following: Warning: MacPorts running without privileges. You may be unable to complete certain actions (e.g. install). ---> Computing dependencies for postgresql-server-devel ---> Dependencies to be installed: postgresql-devel ---> Building postgresql-devel Error: Target org.macports.build returned: shell command failed Error: The following dependencies failed to build: postgresql-devel Error: Status 1 encountered during processing. To report a bug, see <http://guide.macports.org/#project.tickets> So I guess that means I need to running MacPorts with privileges and try again. Unfortunately I've no idea how to give MacPorts privileges. I'm running OS X 10.6.3

  • Applying the Windows Experience Index to Servers

    - by Scott
    I finally convinced upper management that we need a computer replacement plan, and I've been tasked with making an inventory of what we have and determining what needs to be replaced this year, next year, the year after, etc. I had to use some sort of criteria to back up my recommendations, so I decided to try using the Windows Experience Index. I've determined the CPU and Memory scores for all of our desktops and servers using community data. I also feel fairly successful in assigning a WEI score to each user based on their computing needs. I'm struggling with assigning a WEI score to the various servers that we have: file server, database server, Exchange server, backup server (for doing backups), web server. Suggestions would be appreciated.

  • hostapd running on Ubuntu Server 13.04 only allows single station to connect when using wpa

    - by user450688
    Problem Only a single station can connect to hostapd at a time. Any single station can connect (W8, OSX, iOS, Nexus) but when two or more hosts are connected at the same time the first client loses its connectivity.

  • XenServer Converting HVM to Paravirtualised

    - by Karl Kloppenborg
    Recently I have been tasked with the daunting process of converting a setup of HVM enabled VMs (running on Citrix XenServer 5.6.0) into PV (paravirtualised) containers. The constraints of the project was that: The operating system must be functionally identical after the migration. minimal modification to the operating system (with exception of kernel / drive mapping) I also was allowed to change the bootloader(ie, grub) in what ever way I see fit. However, I have attempted this, I will firstly like to show you my steps I took. This at the moment is CentOS5.5 specific: Steps: yum install kernel-xen This installed: 2.6.18-194.32.1.el5xen edited: /boot/grub/menu.lst changed my specs to match: title CentOS (2.6.18-194.32.1.el5xen) root (hd0,0) kernel /vmlinuz-2.6.18-194.32.1.el5xen ro root=/dev/VolGroup00/LogVol00 console=xvc0 initrd /initrd-2.6.18-194.32.1.el5xen.img Then I changed my xenserver parameters to match: xe vm-param-set uuid=[vm uuid] PV-bootloader-args="--kernel /vmlinuz-2.6.18-194.32.1.el5xen --ramdisk /initrd-2.6.18-194.32.1.el5xen.img" xe vm-param-set uuid=[vm uuid] HVM-boot-policy="" xe vm-param-set uuid=[vm uuid] PV-bootloader=pygrub xe vbd-param-set uuid==[Virtual Block Device/VBD uuid] bootable=true Some things to note, I am running a VolGroup LVM ;) Anyways, after all these steps (which aren't much!) I boot the VM and it boots initial kernel just fine, however I am presented with this error: Boot Screen: device-mapper: dm-raid45: initialized v0.2594l Waiting for driver initialization. Scanning and configuring dmraid supported devices Scanning logical volumes Reading all physical volumes. This may take a while... Activating logical volumes Volume group "VolGroup00" not found Creating root device. Mounting root filesystem. mount: could not find filesystem '/dev/root' Setting up other filesystems. Setting up new root fs setuproot: moving /dev failed: No such file or directory no fstab.sys, mounting internal defaults setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory Switching to new root and running init. unmounting old /dev unmounting old /proc unmounting old /sys switchroot: mount failed: No such file or directory Now my hints are that it cannot detect / because of the fact that when you change from HVM mode to PV it does something (not that obvious) When you make a SR (storage) on a HVM, you get it mounted to the guest os as /dev/hda. However in PV mode, this presents itself as /dev/xvda... Could this be the answer? and if so, how the heck to I implement it?? Update: So I have gotten a bit further in my quest, as it now detects the LVM's... To do this, I required to recompile the xen-kernel initrd image. Command: mkinitrd -v --builtin=xen_vbd --preload=xenblk initrd-2.6.18-194.32.1.el5xen.img 2.6.18-194.32.1.el5xen Now when I boot I get this: Boot Screen: Loading dm-raid45.ko module device-mapper: dm-raid45: initialized v0.2594l Scanning and configuring dmraid supported devices Scanning logical volumes Reading all physical volumes. This may take a while... Found volume group "VolGroup00" using metadata type lvm2 Activating logical volumes 3 logical volume(s) in volume group "VolGroup00" now active Creating root device.
