  • How to determine if a device is SATA driven and will be affect by the Sandy Bridge Intel Issue?

    - by joelhaus
    Looking to buy a higher-end Windows 7 laptop, but I'm concerned about the issue with the Intel Sandy Bridge chipset. Otherwise, my price range covers laptops within the latest (Sandy Bridge) generation of the Core i7 family. I understand that there is an issue with SATA ports 2-5 and I use a Windows Home Server over a WiFi connection to share files and backup my PC. The other storage devices that I will use (less frequently) are the built-in DVD-RW disc drive and various devices hooked up to the USB ports (i.e. Android devices, iPod, etc.). The question: Will this setup be negatively impacted by the problem Intel reported about Sandy Bridge? Given this information, is it unwise to purchase a laptop that has this flaw? I really don't know how to determine whether a device is SATA driven or not, so hoping someone can shed some light on this too. Thanks!

  • Spanning-tree setup with incompatible switches

    - by wfaulk
    I have a set of eight HP ProCurve 2910al-48G Ethernet switches at my datacenter that are set up in a star topology with no physical loops. I want to partially mesh the switches for redundancy and manage the loops with a spanning-tree protocol. However, our connection to the datacenter is provided by two uplinks, each to a Cisco 3750. The datacenter's switches are handling the redundant connection using PVST spanning-tree, which is a Cisco-proprietary spanning-tree implementation that my HP switches do not support. It appears that my switches are not participating in the datacenter's spanning-tree domain, but are blindly passing the BPDUs between the two switchports on my side, which enables the datacenter's switches to recognize the loop and put one of the uplinks into the Blocking state. This is somewhat supposition, but I can confirm that, while my switches say that both of the uplink ports are forwarding, only one is passing any real quantity of data. (I am assuming that I cannot get the datacenter to move away from PVST. I don't know that I'd want them to make that significant of a change anyway.) The datacenter has also sent me this output from their switches (which I have expurgated of any identifiable info): 3750G-1#sh spanning-tree vlan nnn VLAN0nnn Spanning tree enabled protocol ieee Root ID Priority 10 Address 00d0.0114.xxxx Cost 4 Port 5 (GigabitEthernet1/0/5) Hello Time 2 sec Max Age 20 sec Forward Delay 15 sec Bridge ID Priority 32mmm (priority 32768 sys-id-ext nnn) Address 0018.73d3.yyyy Hello Time 2 sec Max Age 20 sec Forward Delay 15 sec Aging Time 300 sec Interface Role Sts Cost Prio.Nbr Type ------------------- ---- --- --------- -------- -------------------------------- Gi1/0/5 Root FWD 4 128.5 P2p Gi1/0/6 Altn BLK 4 128.6 P2p Gi1/0/8 Altn BLK 4 128.8 P2p and: 3750G-2#sh spanning-tree vlan nnn VLAN0nnn Spanning tree enabled protocol ieee Root ID Priority 10 Address 00d0.0114.xxxx Cost 4 Port 6 (GigabitEthernet1/0/6) Hello Time 2 sec Max Age 20 sec Forward Delay 15 sec Bridge ID Priority 32mmm (priority 32768 sys-id-ext nnn) Address 000f.f71e.zzzz Hello Time 2 sec Max Age 20 sec Forward Delay 15 sec Aging Time 300 sec Interface Role Sts Cost Prio.Nbr Type ------------------- ---- --- --------- -------- -------------------------------- Gi1/0/1 Desg FWD 4 128.1 P2p Gi1/0/5 Altn BLK 4 128.5 P2p Gi1/0/6 Root FWD 4 128.6 P2p Gi1/0/8 Desg FWD 4 128.8 P2p The uplinks to my switches are on Gi1/0/8 on both of their switches. The uplink ports are configured with a single tagged VLAN. I am also using a number of other tagged VLANs in my switch infrastructure. And, to be clear, I am passing the tagged VLAN I'm receiving from the datacenter to other ports on other switches in my infrastructure. My question is: how do I configure my switches so that I can use a spanning tree protocol inside my switch infrastructure without breaking the datacenter's spanning tree that I cannot participate in?

  • Development Server Blocked Only from Home

    - by theonlylos
    Recently I've been having an issue with my CentOS 6 test server running Apache and Webmin running on port 10000 where when I try accessing any part of the server - SSH/FTP and even my domains (I have two - both keep getting timeout errors) when I try accessing from any computer on my home network. However when I access via tethering or via my office networks everything loads fine. While the firewall is the first issue at mind, my router never was set to block any special ports, and even after adding port 10000 as a specific exception I'm having no luck. Also, I doubt this is an IP blacklisting issue because I have websites on other servers using CloudFlare for security and I haven't gotten any warnings. Any assistance is greatly apprecaiated. UPDATE: Just some extra details about the issue: My ISP to my knowledge only blocks off ports 25 and 80 for residential users to prevent them from running web servers - however this issue has only come up a day or two ago, before that I was using the server successfully for months. Also the server is not physically located in any of my workspaces - it's a VPS housed in a datacenter

  • What causes winsock 10055 errors? How should I troubleshoot?

    - by Tom Kerr
    I'm investigating some issues with winsock 10055 errors on a chain of custom applications (some of which we control, some not) and was hoping to get some advice on techniques to troubleshoot the problem. No buffer space available. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. From research, non-paged pool and ports seem to be the only resources which can cause this error. Is there another resource which might cause 10055 errors? Currently, we have perfmon counters setup on the applications and non-paged pool usage looks low in most circumstances. Open TCP connections looks low and I am unaware of another way to monitor ports. Since it only happens in production, we are unable to use more invasive counters. Is there some other tool or procedure you would recommend to diagnose which application is causing the issue?

  • VMware networking - PortChannel or not?

    - by dunxd
    My ESX hosts each have 8 NICS. I have set up 2 NICs for our iSCSI SAN - each is connected to a different SAN switch. 2 NICs are set up for vMotion and Service Console - these are each connected to a different core switch (ports are trunked with VLANs dedicated to vMotion and Management) I now have four ports left over. Currently we have these set up each going into our default VLAN. Two NICs are connected to one core-switch and two are connected to the other. We decided to aggregate the connections to each switch - so they are teamed at the vswitch end, and port channelled at the physical switch end. I am now reading that port channelling these connections is not particularly useful, perhaps even over complicating things. Is there a particular problem with using port channels for VMware? What method provides the best balance between redundancy and performance?

  • Using QoS to prioritize IP addresses

    - by Tristan
    I have a Western Digital N900 router. I was hoping I'd be able to throttle users based on their MAC address with it, which isn't possible sadly. Seems simple in principle though, duh. The battle against bandwidth hogging roomates rages on. Could I just set the local IP range to their IP, and then set the Local port range to every single port in existence. Then prioritize their IP to lower than mine? Will this work? What are all the ports? And what's the difference between Local and Remote IPs or Ports? Name: Roomate, Priority: Low, Protocol: TCP or UDP ??, Local IP Range: .101 to .101, Local Port Range: 0 to infinity, Remote IP Range: ? to ?, Remote Port Range: ? to ?

  • What are some of the best wireless routers for a price-conscious home power-user?

    - by Alain
    I'm extremely dissatisfied with the 'popular' choice for routers in homes and small offices. They are expensive (upwards of 60$), lack a great deal of useful configuration options, and seem to need to be restarted quite often. (Linksys comes to mind). I've been on the market for a good router lately, and slowly collecting a set of requirements I feel good routers should meet. Maximum number of TCP/IP connections. - This isn't something I see any routers advertise, but in terms of supporting torrent applications, I've been screwed by routers that support less than 20 here. From what I understand a fairly standard number is 200, but there are not so expensive routers that support thousands. Router configuration menu - Most have standard menu's that let you set up basic things like your wireless network encryption settings, uPnP, and maybe even DMZ (demilitarized zones). An absolute requirement for me, however, are routers with good enough firmware to support: Explicit Port forwarding Assigning static local ips to specific mac addresses, or at least Port forwarding by MAC address Port, IP and MAC filtering Dynamic DNS service for home users who want to set up a server but have a dynamic IP Traffic shaping (ideally) - giving priority to packets from certain machines or over certain ports. Strong wireless signal - If getting a reliable signal requires me to be so close to the router that I can connect an Ethernet cable, it's not good enough. As many Ethernet ports as possible. - Because I want to be able to switch from console gaming to PC gaming without visiting my router. So far, the best thing I've stumbled upon (in the bargain bin at staples) was a 20$ retail plus router. It was meant to be the cheapest alternative until I could find something better to purchase online, but I was actually blown away by the firmware capabilities. It supports defining reserved bandwidth for certain network traffic, dynamic DNS, reserving local IPs for specific MAC addresses, etc. At 2 am when my roommate is killing our Internet with their torrents, I can limit their bandwidth without outright blacklisting them. I have, however, met serious limitations when it comes to network traffic between local machines. It claims a 300Mbps connection, but I have trouble streaming videos from my PC to my console or other laptops wirelessly. It has a meltdown and needs to be reset once in a while (no more than a couple times a month), and it's got a 200 connection limit. There 4 Ethernet ports in the back but I'm pretty sure the first doesn't work. So some great answers to this question would be: Any metrics you use to compare routers, and requirements you have for new candidates. The best routers you've found for supporting home servers, file management systems, high volume torrent traffic, good price/feature ratio, etc. Good configuration advice (aside from 'use Ethernet whenever possible') Thanks for your feedback and experiences!

  • Has anyones successfully configured mutt for GMail on FreeBSD? If so, how?

    - by Hank Gay
    I've tried following the instructions here and here. Currently, I can read email from my GMail account, but not send—this is on a personal computer, so even if I configured Sendmail, I doubt any of the mail would survive the spam filter gauntlet. Both guides seem to require the --enable-smtp option for mutt, which I don't think is being exposed by ports. I've tried the mutt and mutt-devel ports and neither seem to give me that option. On a far less important note, I also haven't been able to change folders, e.g., I get told that Sent Mail is not a valid folder when I attempt to go into it. If you can troubleshoot this problem, it's pure gravy. I really only care about sending. Thanks, Hank

  • HID USB Very Strange Problem...

    - by Lasanha
    I realy hope some one can help me here cause i search all over the web and nothing comes up.. I allways used PS/2 KB and Mouse and a USB KeyPad (Genius ErgoMedia 500 Gaming Explorer) to play some games, mmorpg, fps, you named, very good whit 11 keys whit possible macros etc etc... Now it comes the problem, i have a USB mouse that have 4 extra buttons, and i need more button, i love buttons.. Well, i plug in the USB mouse and disconectes de PS/2. Everything is ok until i toutch the mouse. If i do so, the ErgoMedia goes off, then on, then i mouse the mouse or press a button and all over again. Yesterday i went buying a new mouse that i liked, a USB mouse too (NPlay whit macros and all that stuff 3600dpi...) Hoping the problem was only whit the other mouse, but no.. It does the exact same thing, ErgoMedia keeps disconecting and conecting everytime i toutch the mouse. What i allready did: Update drivers of both mouses Update drivers of ErgoMedia (no specific drivers(Windows based)) Update drivers of MB Chipset (Actualy no, cause it was up to date allready) Trying other USB Ports (4 Ports back, 4 Ports Front and even 1 Port in 16 card slot device) Disable the "Allows Windows to shut down the energy bla bla" thing in Device Setings. Look up in the Device Setings only apear a problem on the ergomedia (Human interface Device) when i move the damm mouse.. Using Everest to read behavier, everything normal, exepts the disconecting thing, but no errors. Not a power suply, only the ErgoMedia and the mouse are in the USBs, and i allready disable the 16 card reader whit one usb slot to see.. Clean the IRQ registry. Look the entire internet for a fix solution. Help others problems wile looking for a fix for me (Im not a pro but not a completly stupid) Talking to you beggin you to help me as a last resorce... Machine: Acer M3641 Core2Quad 64x Based OS Vista 64b 4GbRAM HD Audio and Graphics I realy hope some one out there knows a fix for this, maybe it´s a simple thing, so simple that i´m to stupid to see that..

  • Extend my LAN network

    - by user268291
    i have a patch panel and hardwiring already setup in my office. The patch panel is 24-port and all the ports are engaged. All my switch ports are engaged. Now, I have a printer connected to a wall point (RJ45) which I want to shift to a new room where there is no LAN setup. I want to have two RJ45 wall plugs in the new room so that I can connect one RJ45 port to have my LAN in the new room and the other RJ45 wall port I want to use for my printer. There is no option other than LAN (no wireless). Please help me and tell me how do I get the two RJ45 wall plate plugs in the new room up and keep my LAN running. It is a little urgent for me. Please help.

  • Multiple VLAN on one switch port

    - by Macropus
    I have a HP ProCurve 1810G-8 which I currently use as a normal switch between 3 servers and a firewall. 2 of the servers are ESXi hosts, and one is a Nexentastor box with 2 iSCSI target LUNs. As the iSCSI traffic is on the same LAN as all other traffic, I would like to switch this to use a SAN for iSCSI traffic and the LAN for all other traffic. The Nexentastor box only has 2 NICs, and as such, with a physical arrangement, I presume that one must be plugged into the SAN VLAN and one on the LAN VLAN ports of the switch. Is there a way to have multiple VLANs over the same port? e.g. the Nexentsator box has 2 NICs, both plugged into the switch, both ports with access to both of the VLANs?

  • DYNDNS setup with TightVNC on Windows Server 2008 R2

    - by StealthRT
    Hey all, i seem to be having a problem with getting ports to forward on my Windows Server 2008 R2 PC. I already set all my port forwarding for 5900/5800 on my router for my PC's IP address (192.168.1.22) but when i try to use the TightVNC PFPortChecker on port 5900 it tells me its not opened! I can not even connect to my DYNDNS server name (xxxxxxx.dyndns.org). As a side note, i am running Windows XP SP3 within a VirtaulBox inside Windows Server 2008 R2 but running the PFPortChecker in Windows 2008 R2 brings the same results as it does in the VM. I also added them to the Windows Firewall Advanced Security form to add those inbound ports for full access. What could i possibly be missing? Thanks for your time! David

  • Bug in CDP implementation

    - by Suraj
    We are developing a Linux based ethernet switch which has 6 ports. We are done with CDP protocol. I have connected a Cisco device to port 2. When I quiery for the Cisco device, I get the reply and instead of getting lan1 (port 1 - lan0 .. port 6 = lan5), I always get the interface name as eth0. The same is the case for all the ports. What changes are required to get the correct interface name? I will be very thankful for the information. The snap packet is received in the routine snap_rcv() in the file "linux._2.6.XX/net/802/psnap.c"; Regards, Suraj..

  • Tomato QoS: Why is some traffic unclassified when there are classifications for it?

    - by Armitage
    Ok, I am trying to tweak my router to give priority to some traffic. My classifications seem to cover just about everything but I still see ~60 to ~80% of the traffic as unclassified: TCP 192.168.1.100 64137 192.168.1.1 80 Unclassified TCP 192.168.1.100 64175 192.168.1.1 80 Unclassified TCP 192.168.1.100 64144 192.168.1.1 443 Unclassified I assume that the 64### ports are just what my WAP uses to send packets inside my home network. But my classifications seems to cover any traffic for destination ports 80 and 443: (partial list) TCP Dst Port: 80,443 High WWW TCP/UDP Dst Port: 1024-65535 Lowest Bulk Traffic Why do I have so much unclassified traffic if I have a classification that should cover it?

  • Cannot see http (apache) server outside home network

    - by user165155
    Ive been racking my brain with this all evening. Power went out with a tstorm today, started back up my server... running apache and a team speak server on it. TS is great, cant see my web page outside my network! Firewall is disabled on the pc running it (centos btw), apache is running and working. correct ports are forwarded on my router (my isp blocks port 80). Ive tried changing ports, pretty much everything i can think of. httpd.conf is pointing to the correct addy and port, and my domain is pointing to the correct external ip. Im at a loss, any ideas out there?

  • USB 3.0 not functioning fully

    - by Simon Sheehan
    After installing GNU/Linux today onto my Lenovo Y570 laptop, I ran into an issue quickly - the USB 3.0 support. 2/3 of my USB ports are 3.0 so I kind of need them. The ports are powered at the very least - my phone is charging from one, however, plugging in external drives, USB drives, or even a mouse gives no response. The drives spin up, etc, but they do nothing more than that. So there is power, but no information flowing to them. What am I missing here? What can I try to enable to make things work?

  • HP ProCurve Port Mode Configuration Question Mark 2

    - by SvrGuy
    We have a ProCurve Switch 2810-48G (J9022A). We need to disable auto negotiation on two ports and manually configure them to be full duplex gige ports. From the web GUI, Configuration Tab, Port Configuration sub tab, I am only presented with the option to configure the port as Auto - 1000. I take this to mean, auto negotiate duplex, manually configure the speed to be gige. From the CLI when I try to set 1000-full I get the following error: Value 1000-full is not applicable to port 39 (or whatever port I try) The exact commands I have entered are: config interface 39 speed-duplex 1000-full BTW: speed-duplex auto-1000 works ( I also tried full-1000 and that did not work either) How do I manually configure the port such that it is manually configured to use full duplex, 1000 mbs?

  • Security question pertaining web application deployment

    - by orokusaki
    I am about to deploy a web application (in a couple months) with the following set-up (perhaps anyways): Ubuntu Lucid Lynx with: IP Tables firewall (white-list style with only 3 ports open) Custom SSH port (like 31847 or something) No "root" SSH access Long, random username (not just "admin" or something) with a long password (65 chars) PostgreSQL which only listens to localhost 256 bit SSL Cert Reverse proxy from NGINX to my application server (UWSGI) Assume that my colo is secure (Physical access isn't my concern for the time being) Application-level security (SQL injection, XSS, Directory Traversal, CSRF, etc) Perhaps IP masquerading (but I don't really understand this yet) Does this sound like a secure setup? I hear about people's web apps getting hacked all the time, and part of me thinks, "maybe they're just neglecting something", but the other part of me thinks, "maybe there's nothing you can do to protect your server, and those things are just measures to make it a little harder for script kiddies to get in". If I told you all of this, gave you my IP address, and told you what ports were available, would it be possible for you to get in (assuming you have a penetration testing tool), or is this really protected well.

  • Windows 7 USB power lose after a few seconds / minutes

    - by Stefan Dunn
    My friend's computer has a problem where the USB ports causes problems with the power of some devices connected to the computer. The USB mouse has no problems, however the Wireless Adapter looses power after around 20 seconds of use and USB Flash Drives cause the computer to either freeze, lose power (and become unresponsive) or become disconnected (still shown in Device Manager, but not in My Computer) when trying to transfer any type of file to / from the computer. I have a suspicion it's the Motherboard but could it also be a Software problem? Tried a new case, RAM, CPU and GFX Card which had no effect. The problem occurs on both the Front USB and Back (Motherboard) USB Ports. UPDATE: Tried the USB devices with an Ubuntu Live CD and they work fine, could this mean it's a problem with Windows (x64)?

  • Link aggregation with freebsd8 and a cicso 3550, what am i doing wrong?

    - by Flamewires
    Hey, I am trying to setup Link Aggrigation with LACP (well, anything that provides increased bandwidth and failover using my setup will work). I'm running FreeBSD 8.0 on 3 machines. M1 is running 2 10/100 ethernetcards setup for link aggrigation using lagg. for reference: ifconfig em0 up ifconfig tx0 up ifconfig create lagg0 ifconfig lagg0 laggproto lacp laggport tx0 laggport em0 192.168.1.16 netmask 255.255.255.0 I plugged them into ports 1 and 2 of a Cicso 3550. then ran: configure terminal interface range Fa0/1 - 2 switchport mode access switchport access vlan 1 channel-group 1 mode active (everythings in vlan 1) Now Im able to connect the other computers to other ports on the switch and failover works great, i can unplug cables in the middle of a transfer and the traffic gets rerouted. However, im not noticing any speed increase. My test setup: load balancing: i tried dst and src on the switch, neither seemed to give me a speed increase. I am SCPing 2 500 meg files from the lagg computer to other computers (one each) which are also running 10/100 full duplex cards. I get transfer speeds of about 11.2-11.4 Mbps to a single host, and about half that (5.9-6.2) Mbps when transferring to both at the same time. From what I understood with destination load balancing the router was suppose to balance traffic headed for 1 computer over 1 port and traffic headed for another over a diff(in this case) the other port. With destination-MAC address forwarding, when packets are forwarded to an EtherChannel, the packets are distributed across the ports in the channel based on the destination host MAC address of the incoming packet. Therefore, packets to the same destination are forwarded over the same port, and packets to a different destination are sent on a different port in the channel. For the 3550 series switch, when source-MAC address forwarding is used, load distribution based on the source and destination IP address is also enabled for routed IP traffic. All routed IP traffic chooses a port based on the source and destination IP address. Packets between two IP hosts always use the same port in the channel, and traffic between any other pair of hosts can use a different port in the channel. (Link) What am i doing wrong/what would i need to do to see a speed increase beyond what i could do with just a single card?

  • Connecting my XBOX 360 to home network

    - by patrick
    I am trying to set up my XBOX 360 as a Windows Media Center Extender. I input the code as shown on the XBOX screen, but I get the error message: "Cannot Set Up Extender." This means that the Extender was found (there's a separate error msg for extender not found), however it can't be set up. Windows points me to this page which tells me to change my router settings to enable multicast and UPnP. My router doesn't have those specific settings but I did open all ports for the XBOX. What is odd about this problem is that it did work, then I restarted my computer and didn't change any settings, and now it doesn't work. I guess something did change, but I can't figure out anything else to try after opening all ports. I'm running Windows 7 and the router is fairly recent (I bought it about six months ago) so it should be able to handle this. The router firmware is up to date.

    I have a webserver (Ubuntu 12.04 with LAMP) using Virtualmin / Webmin. Because I just moved from a Cpanel system, I am having a nightmare configuring the DNS! Using intoDNS.com, the failed reports are: Mismatched NS records WARNING: One or more of your nameservers did not return any of your NS records. DNS servers responded ERROR: One or more of your nameservers did not respond: The ones that did not respond are: 123.123.123.123 213.251.188.141x Multiple Nameservers ERROR: Looks like you have less than 2 nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me. Missing nameservers reported by your nameserver You should already know that your NS records at your nameservers are missing, so here it is again: ns1.mydomain.com. sdns2.ovh.net. SOA record No valid SOA record came back! MX Records WWW A Record ERROR: I could not get any A records for www.mydomain.com! Step-by-Step of my Attempt In my domain registrar (Namecheap), I registered ns1.mydomain.com as a nameserver, pointing to the IP address of my web server which is running bind9. The domain is setup with DNS ns1.mydomain.com and sdns2.ovh.net. sdns2.ovh.net is a secondary DNS server (SLAVE and pointing mydomain.com to the IP address of my web server) Webserver domain: mydomain.com Webserver hostname: ns4000000.ip-123-123-123.net Webserver IP: 123.123.123.123 Under Virtualmin, I edited the default Virtual server template, BIND DNS records for new domains: ns1.mydomain.com Master DNS server hostname: ns1.mydomain.com Next I created a Virtual server using that server template. This is what I've done but its still not working! Any ideas? I've been stuck for days, thank you for all your help! service bind9 status * bind9 is running lsof -i :53 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME named 6966 bind 20u IPv6 338583 0t0 TCP *:domain (LISTEN) named 6966 bind 21u IPv4 338588 0t0 TCP localhost.localdomain:domain (LISTEN) named 6966 bind 22u IPv4 338590 0t0 TCP ns4000000.ip-123-123-123.net:domain (LISTEN) named 6966 bind 512u IPv6 338582 0t0 UDP *:domain named 6966 bind 513u IPv4 338587 0t0 UDP localhost.localdomain:domain named 6966 bind 514u IPv4 338589 0t0 UDP ns4000000.ip-123-123-123.net:domain /etc/resolv.con (Not sure how 213.186.33.99 got here) nameserver 127.0.0.1 nameserver 213.186.33.99 search ovh.net host 123.123.123.123 (my web server's IP) 13.60.245.198.in-addr.arpa domain name pointer ns4000000.ip-123-123-123.net. nslookup 213.186.33.99 Server: 127.0.0.1 Address: 127.0.0.1#53 Non-authoritative answer: 99.33.186.213.in-addr.arpa name = cdns.ovh.net.
