  • Strange performance issue with Dell R7610 and LSI 2208 RAID controller

    - by GregC
    Connecting controller to any of the three PCIe x16 slots yield choppy read performance around 750 MB/sec Lowly PCIe x4 slot yields steady 1.2 GB/sec read Given same files, same Windows Server 2008 R2 OS, same RAID6 24-disk Seagate ES.2 3TB array on LSI 9286-8e, same Dell R7610 Precision Workstation with A03 BIOS, same W5000 graphics card (no other cards), same settings etc. I see super-low CPU utilization in both cases. SiSoft Sandra reports x8 at 5GT/sec in x16 slot, and x4 at 5GT/sec in x4 slot, as expected. I'd like to be able to rely on the sheer speed of x16 slots. What gives? What can I try? Any ideas? Please assist Cross-posted from http://en.community.dell.com/support-forums/desktop/f/3514/t/19526990.aspx Follow-up information We did some more performance testing with reading from 8 SSDs, connected directly (without an expander chip). This means that both SAS cables were utilized. We saw nearly double performance, but it varied from run to run: {2.0, 1.8, 1.6, and 1.4 GB/sec were observed, then performance jumped back up to 2.0}. The SSD RAID0 tests were conducted in a x16 PCIe slot, all other variables kept the same. It seems to me that we were getting double the performance of HDD-based RAID6 array. Just for reference: maximum possible read burst speed over single channel of SAS 6Gb/sec is 570 MB/sec due to 8b/10b encoding and protocol limitations (SAS cable provides four such channels).

  • Vista ICS issue

    - by Bill Grey
    I have a strange problem with Internet Connection Sharing on a laptop running Vista Business. This laptop is connected to the internet via the ethernet port, which goes to an ADSL modem. it is automatically assigned the IP address 192.168.1.50, and the modem/gateway is 192.168.1.1 My friends laptop is running Vista Home. Previously, I would create an ad hoc wireless network, enable ICS, and everything would be perfect. My friend would have internet access via this. However, something has now mysteriously broken. If I enable ICS on the wireless connection, it resets my Local Area Connection, assigning it the manual IP address of 192.168.0.1, which means my connection to the internet is destroyed. Both wireless adapters on each network are assigned auto configuration addresses, in the 168. range. They can see each other fine, but my friends laptop cannot access the internet via mine, even after I have restored the Local Area Connection settings. I understand the computer with ICS enabled must have the IP of 192.168.0.1, but previously, before whatever went wrong, my wireless adapter would be 192.168.0.1 and my friends computer would get an IP via DHCP. I have also tried setting static IP address and making a bridge, none of which works. How can I fix this problem, and prevent enabling ICS from touching my Local Area Connection? Both machines have no firewall, have appropriate settings etc...

  • BOINC permissions issue running as non-admin on Windows PC

    - by sunpech
    I installed BOINC (running World Community Grid) on a PC (running Vista) under an administrator's account. When logged in as a standard user, and BOINC is set to run as a screensaver, it fails to connect and run properly. Only when the program is run as an administrator, does it actually run in the standard user's account. What is the correct way to install and run BOINC for standard users (non-admin) on Windows? -- Not specific to Vista necessarily.

  • Contacts Issue: Google Contacts, Nokia 5800 And Outlook, Sync and Images

    - by josecortesp
    Hello everyone, this is a multi-question, so please, feel free to answer just one or all of them. My actual situation is: Google contacts sync with Nokia 5800 using MFE(google sync), using google's fake "exchange server". Outlook sync with google using GoContact Sync software (http://www.webgear.co.nz/Products/GOContactSync.aspx). What I want, a easy(or not) way to correctly sync the three of them, even if I have to change some of my "escenario". I know outlook<-google contacts sync is not good yet, but if someone can suggest me some better SW than GoContact Sync. It'll be good. What I really want is to sync a least name, phone, email and image. Then, is there a way to get all my google contacts to by default use their own google image? I noted that, usually i have to manually choose it, and sometimes it doesn't work. I'll like to use something or someone's service to do this automatically. I have tried some services like Soocial, but it gives me a lot of trouble after the first sync, because soccial can ONLY get ALL your contacts, not just "My Contacts"; and also it gives me like 100 bad contacts in outlook because of their beta client. The final goal of all of this is to Get only "My Contacts" from google in Outlook and in the 5800 with their images Get ALL my contacts with their default image, meaning, the contact's personal image Get a solution to correctly sync the three of them, using Google's as the base for the rest of them. Thanks in advance. Again, feel free to sugest me solutions to just one or all them.

  • Sendmail Issue - Local Mail / Inner Domain Mail

    - by ngl5000
    Environments: Ubuntu / Sendmail / Google Apps Emailing: I send and receive all of my emails through google apps besides emails that are sent directly from my website. My Web Domain: example.com (for the purpose of the question only) Problem: When my website sends an email, using sendmail, to any local address ([email protected]) I get an unknown user error. Emails sent to other domains seem to work just fine. Question: I believe this is because I don't have these users defined on my ubuntu server, this is besides the point I need to configure sendmail such that it doesn't pick out local emails sent to ([email protected]) and instead finds their name server which points to google apps and sends it there instead. This is my first try at serverfault, I normally use stackoverflow so let me know if I'm messing up! Thank you!

  • Repeated Reporting Services Login issue when deploying through BIDS to a remote server

    - by Richard Edwards
    We are having a problem deploying a reporting services report to a sql reporting services computer that is configured in SharePoint Integrated mode. I can successfully deploy to the SharePoint document libraries set up for reports and data connections if I do it locally from the box that SharePoint and Reporting Services are deployed on. If I try and do the same thing with the exact same deployment properties from a remote box, I constantly get a Reporting Services Login dialog popping up and no combination of domain\username and password will work. I've even tried the machines local admin account and still nothing. Any ideas where to start looking?

  • Cisco SG200 vlan issue in ESXi VSA cluster

    - by George
    I have three Cisco SG200-26 switches, and I also have two ESXi hosts that I have connected like shown in the below "best practice" map by VMware: http://communities.vmware.com/servlet/JiveServlet/previewBody/17393-102-1-22458/VSA_networking_map.pdf Even though I created the VLANs in the SG200 and I set the two VLANs (508 and 608) as allowed for these untagged ports (where my ESX NIC's are connected), I can not ping from host 1 to host 2 when configuring the NIC's to use 608 VLAN. Am I missing something? my IP's are all in the 192.168. range, and the only reason I need the VLANs is to isolate the traffic of VSA back-end internally, only the two hosts will be using the VLANs. So I think I do not have to create virtual interfaces on my router since that's the case, is my understanding correct? Also sending my switch config screenshot below.. all 3 switches have the latest firmware (it seems these were originally linksys and got rebranded as cisco after the acquisition) http://img31.imageshack.us/img31/2503/switch.gif Any ideas what to change on the Cisco SG200 to make this work , would be appreciated! The second VLAN (608) only needs two IP's: 192.168.0.1 and 192.168.0.2 The first VLAN (508) will have about 15 IP's for ESXi Management and VSA cluster service, I could use either 192.168.1.xx or 10.0.1.xx The rest of my network (about 50 clients) is in 192.168.1.xx range VMware also states that the VLAN protocol on the physical switch must be 802.1Q, not ISL, anyone knows which of the two my SG200-26 uses? In addition to that, the only requirement from VSA is that my two hosts: -Are in the same subnet. -Have static IP addresses set. -Have the same Default Gateway configured. If I need inter-vlan routing for this, I suppose I have to create virtual interfaces on my sonicwall, and assign an IP for each VLAN, and then set routes between them? Thank you for your time!

  • How to avoid intrusion detection/anti spoofing issue on a sonicwall TZ series FW

    - by Ian
    We have a sonicwall tz series FW with two internet service providers connected. One of the providers has a wireless service which works a bit like an ethernet switch in that we have an ip with a /24 subnet and the gateway is .1. All other clients on the same subnet (say 195.222.99.0) have the same .1 gateway - this is important, read on. Some of our clients are also on the same subnet. Our config: X0 : Lan X1 : 89.90.91.92 X2 : 195.222.99.252/24 (GW 195.222.99.1) X1 and X2 are not connected, other than both being connected to the public Internet. Client config: X1 : 195.222.99.123/24 (GW 195.222.99.1) What fails, what works: Traffic 195.222.99.123 (client) <- 89.90.91.92 (X1) : Spoof alert Traffic 195.222.99.123 (client) <- 195.222.99.252 (X1) : OK - no spoof alert I have several clients with IPs in the 195.222.99.0 range and all provoke identical alerts. This is the alert I see on the FW: Alert Intrusion Prevention IP spoof dropped 195.222.99.252, 21475, X1 89.90.91.92, 80, X1 MAC address: 00:12:ef:41:75:88 Anti-spoofing is switched off on my FW (network-mac-ip-anti-spoofing - config for each interface) for all ports I can provoke the alerts by telneting to a port on X1 from the clients. You can't argue with the logic - this is suspicious traffic. X1 is receiving traffic with a source IP which corresponds to X2s subnet. Anyone know how can I tell the FW that packets with a src subnet of 195.222.99.0 can legitimately appear on X1? I know whats going wrong, I've seen the same thing before, but with higher end FWs you can avoid this with a few extra rules. I can't see how to do this here. And before you ask why we're using this service provider - they give us 3ms (yep 3ms, thats not an error) delay between routers.

  • xp vpn client dns issue

    - by David Archer
    Hi All, I have a problem with dns when connected to my work vpn. For ease of explanation I'll use the following in my outline of the problem: - name of my machine on work network is REMOTE_XP (original i know) - ip of my machine on work network is 192.168.2.80 - name of my machine on my local network is LOCAL_XP - ip of my machine on my local network is 10.0.0.3 What I want to be able to do when connected to vpn: - browse the internet from LOCAL_XP - ping by name REMOTE_XP Now it seems I've so far mentioned either 1 but not both of my wishlist. If i go to my vpn network properties (on LOCAL_XP) and uncheck the "use default dns on remote network" then I can browse the internet from my local machine but can't ping REMOTE_XP (though I can ping 192.168.2.80) If I check "use default dns..." then I can ping REMOTE_XP but can't browse the internet from LOCAL_XP. Is there a way I can have my dns cake and eat it, or will I have to accept that it will be an either/or situation? Thanks in advance.

    ok, this is really pissing me off I have one ubuntu 8.04 instance running on vmware (esx) which decided after a reboot to stop resolving dns requests, I also cant connect to it using ssh although I can ping the server and its really that server (when I shutdown the server the ping also stops) stuff I tried: - reboot again :) - nslookup - serverip - setting networking to dhcp - offering some cute kittens to lucifer - removing the virtual nic and adding another (to get a different mac) - migrating the instance to another esx host - drinking 20 cups of espresso - stopped all services - running dnsmasq on another server and connecting to that dns - tcpdumping - disabling ip6 symptoms: cant resolve anything nslookup just says "no servers found..." although I can ping the servers traceroute to gateway doesnt work (even with traceroute -4 -n gatewayip) collegues laughing at me any thoughts

  • Weird routing issue

    - by Joel Coel
    I'm having some weird internet problems on campus. I know it's something simple, but it's a case where I need another set of eyes. I think I can explain the problem best by posting a tracert: Tracing route to google.com [74.125.45.147] over a maximum of 30 hops: 1 3 ms 3 ms 3 ms 192.168.8.1 2 1 ms 1 ms 1 ms elissaemily-pc.york.edu [192.168.10.5] 3 2 ms 2 ms 2 ms rrcs-76-79-19-33.west.biz.rr.com [76.79.19.33] 4 31 ms 3 ms 2 ms ge-1-1-0.lnclne00-mx41.neb.rr.com [76.85.220.109] 5 20 ms 17 ms 17 ms ge-7-3-0.chcgill3-rtr1.kc.rr.com [76.85.220.137] 6 20 ms 20 ms 19 ms ae-5-0.cr0.chi30.tbone.rr.com [66.109.6.112] 7 19 ms 19 ms 24 ms ae-1-0.pr0.chi10.tbone.rr.com [66.109.6.155] 8 26 ms 24 ms 24 ms 74.125.48.109 9 23 ms 24 ms 21 ms 216.239.46.246 10 39 ms 39 ms 55 ms 209.85.242.215 11 39 ms 39 ms 39 ms 209.85.254.243 12 39 ms 40 ms 96 ms 209.85.253.145 13 39 ms 39 ms 39 ms yx-in-f147.1e100.net [74.125.45.147] Trace complete.

  • Ubuntu web server 11.10 ftp/server issue

    - by Nate
    I was wondering if I could get some help with FTP, atleast I'm pretty sure it has to do with FTP. Although it could have to do with something else, I'm not 100% sure.. Now, for fare warning, I'm no ubuntu dominator, I'm pretty newb. Anyway, I've attempted to build a webserver to to test php and what not for a site I'm building. Now everything works, the php, the sql etc. By the way, I built this in VMware, so it's virtual, over a network, so I can access stuff from anywhere. I'm in a college right now so yeah. The one problem I have is this. I go into the terminal, and do ifconfig to find my IP. I get it and go to a browser on a different machine and type that IP in. I get the "index of/" page, where I can browse the website I'm making. I can click through folders and what not. I can click on things and they open up. Now lets say I'm working on my desktop and open up an FTP and drag and drop something into there, go to the IP in the browser again and try to open it. I either get "Server error The website encountered an error while retrieving http://my_server_ip/phpinfo.php. It may be down for maintenance or configured incorrectly. Here are some suggestions: Reload this webpage later." or "Forbidden You don't have permission to access /html.html on this server." But, lets say I make it on the server itself, and try, bam, magic it works. I'm sure I set the permissions to let everyone open and view the files, but maybe I didn't? I'm not sure, and this is where I was hoping I could get some help. By the way, I followed a tutorial on changing the www folder (apache) from /var/www to home/"user"/www. I can't recall how I did that, but it's there and my ftp goes to the home/"user"/www folder. But yeah, any and all help is appreciated. Like I said, I'm really new to this, but I do enjoy attempting to make these servers and learning how they work, so it's not like making this webserver is a project for a class, It's just assisting me in testing stuff for another class and possibly other websites later on down the road. Anyway, anyone who decides to help, thanks so much, I'd really appreciate it. Nate. P.S. I'm using Ubuntu 11.10 desktop edition with a LAMP server

  • HAproxy - Redirect issue - Uri Variables ?

    - by Justin
    I'm using haproxy 1.5dev3 and I was wondering if there is any possible way to grab uri variables from a request to reappend the query on the end of a redirect url? What I'm trying to do is redirect from: http://www.domain.com/page/example.htm?id=1234567 to: http://www.domain.com/frame/newpage.cfm?id=1234567 redirect prefix doesn't work properly as it tries to append /page/example.htm to the end of the redirect url. Can I do some sort of rewrite to accomplish this? It would be awesome if you could use uri and queries as variables for redirection/pool selection like on F5. Please help...Thanks!

  • Remote Sending of Emails via SMTP/EXIM Issue

    - by Christian Noel
    I have been encountering a problem when sending messages via EXIM. Here is the scenario: I have 2 servers lets just say host1.com = where all my apps and programs are hosted. host2.com = is another server which handles some apps but is also my smtp mail server. whm and cpanel are installed in both hosts as well as exim. right now, messages are being sent out as [email protected] to clients. host1.com uses the [email protected] so that it can send messages outbound as well. here's the problem, after a few hours from a fresh reboot of host1.com, sending messages from host1.com is no longer possible because i encounter an error that states: system/vendor/swift/Swift/Connection/SMTP.php [309]: The SMTP connection failed to start [tls://mail.host2.com]: fsockopen returned Error Number 110 and Error String 'Connection timed out'` also note that this was working fine earlier (like 10 hours ago) but then it suddenly fails. everytime i restart the host1.com then sending messages will work again. i have checked logs and traces but to no avail the only means of fixing this problem is restarting host1.com.
