  • Router to WIFI Client to Router (New solution for distance when repeater doesnt help)

    - by Kangarooo
    Ethernet to TL-WR340G with WIFI enabled Using TL-WA500 tried repeater mode which was not good enough and had password problems (could not connect if using either ASCII or Normal password in one way then in repeater worked other way) and also could not forward (repeat) WPA/WPA2 security. So since this repeater can also be as client, I made it as client and used another router (TL-WR740N) to get from wire connection from that client and all was working for a little bit. Every machine is set up to be auto DHCP. 1st when setting up client mode I found it working after doing reset. Then after some tens of minutes internet stopped working. When I removed WiFi client then all went back to normal. Where is the problem and how to make this work? Ethernet- TL-WR340G(AutoDHCP) ==> wifi ==> TL-WA500 TL-WA500 wifi client mode(AutoDHCP) ==> wire ==> TL-WR740N TL-WR740N router mode (AutoDHCP) ==> My Computer In other words: TL-WR340G ) ) ) ) TL-WA500 ===== TL-WR740N ==== PC1 ) ) WiFi === Wire

  • Dante (SOCKS server) not working

    - by gregmac
    I'm trying to set up a SOCKS proxy using dante for testing purposes. However, I can't even get it to work with a web browser, after looking at several tutorials on how to do that. I've tried in both IE and Firefox, in both cases, using "Manual proxy configuration", leave everything blank except for SOCKS host, and then put in the IP of my proxy and the port number (1080). I just get "Server not found" / "Problems loading this page" and don't see anything in danted, even running in debug mode. If I do a "telnet 10.0.0.40 1080" I do see the connection open in danted debug output, so I know that much is working. Here's my config: logoutput: stdout /var/log/danted/danted.log internal: eth0 port = 1080 external: eth0 method: username none #rfc931 user.privileged: proxy user.notprivileged: nobody user.libwrap: nobody connecttimeout: 30 # on a lan, this should be enough if method is "none". client pass { from: 10.0.0.0/8 port 1-65535 to: 0.0.0.0/0 } client pass { from: 127.0.0.0/8 port 1-65535 to: 0.0.0.0/0 } client block { from: 0.0.0.0/0 to: 0.0.0.0/0 log: connect error } block { from: 0.0.0.0/0 to: 127.0.0.0/8 log: connect error } pass { from: 10.0.0.0/8 to: 0.0.0.0/0 protocol: tcp udp } pass { from: 127.0.0.0/8 to: 0.0.0.0/0 protocol: tcp udp } block { from: 0.0.0.0/0 to: 0.0.0.0/0 log: connect error } I'm sure I'm probably missing something simple, but I'm lost. I haven't even thought about SOCKS since the late 90's.

  • Nginx + PHP5-FPM repeated cut outs 502

    - by James
    I've seen a number of questions here that highlight random 502 (Nginx + PHP-FPM = "Random" 502 Bad Gateway) and similar time outs when using Nginx + PHP-FPM. Even with all the questions, I'm still unable to find a solution. Using Ubuntu 10.10 + Nginx + PHP5-FPM + APC and every 1 out of 4 requests ends in a timeout and failure. This isn't a load issue or large traffic, it happens even in dev environment with one person. I am doing this across 3 1GB machines, each with the same configurations and same problems. fastcgi_params fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param REDIRECT_STATUS 200; /etc/php5/fpm/main.conf ; FPM Configuration ; ;include=/etc/php5/fpm/*.conf ; Global Options ; pid = /var/run/php5-fpm.pid error_log = /var/log/php5-fpm.log ;log_level = notice ;emergency_restart_threshold = 0 ;emergency_restart_interval = 0 ;process_control_timeout = 0 ;daemonize = yes ; Pool Definitions ; include=/etc/php5/fpm/pool.d/*.conf /etc/php5/fpm/pool.d/www.conf [www] listen = 127.0.0.1:9000 ;listen.backlog = -1 ;listen.allowed_clients = 127.0.0.1 ;listen.owner = www-data ;listen.group = www-data ;listen.mode = 0666 user = www-data group = www-data ;pm.max_children = 50 pm.max_children = 15 ;pm.start_servers = 20 pm.min_spare_servers = 5 ;pm.max_spare_servers = 35 pm.max_spare_servers = 10 ;pm.max_requests = 500 ;pm.status_path = /status ;ping.path = /ping ;ping.response = pong request_terminate_timeout = 30 ;request_slowlog_timeout = 0 ;slowlog = /var/log/php-fpm.log.slow ;rlimit_files = 1024 ;rlimit_core = 0 ;chroot = chdir = /var/www ;catch_workers_output = yes

  • SATA HDD stuttering on reads (LED on)

    - by jdehaan
    I hope I can get some new ideas to solve the issue. What I have: AMD Phenom II X4 905e Box, Sockel AM3 Gigabyte GA-MA790XTA-UD4, AMD 790X, AM3 ATX WD Caviar GreenPower 1,5TB SATA II 4GB Kit OCZ DDR3 PC3-10666 Platinum Low-Voltage CL7 HIS HD 4670 iSilence4 DDR3 1024MB Native HDMI Dual-DVI, PCI-Express Behavior: Everything works normally excepting the HDD accesses. The drive seems to get stuck in reading data (LED drive by Mainboard is on for a while) then recovers and goes on. There is a delay of more than 30s sometimes. Often it is a matter of 5-10s. This does not seem related to the workload of the disk. What I tried so far: Use different SATA port: I switched from the SATA3 to SATA2 then the SATA driven by the CPU, no difference. Turned AHCI off, drove the SATA in IDE mode, same behavior, now I felt like the HDD has problems Deactivated energy saving settings (BeQuiet, ...), disabled 3 CPUs (msconfig) supposing some race condition or trouble with changing freqs, same trouble With Windows7 Professional 64Bit, I installed the hotfix http://support.microsoft.com/?scid=kb%3Ben-us%3B976418&x=8&y=9 with no success. The problem description matches what I experienced, so I felt lucky but was quite in a sad mood after being deceived. Burned the DLG 5.04f DataLifeGuard CD from WD to check the drive. All tests passed, to my surprise! Installed an Ubuntu on the same drive i386 flavour. Drive still in IDE mode, exactly the same behavior. So the OS does not matter. What I did not try yet: http://www.gigabyte.eu/Support/Motherboard/BIOS_Model.aspx?ProductID=3263 I have a F2 BIOS and there is a F3a Beta, did someone have similar issues that were solved by this update? It is a beta so I fear upgrading a bit and I could find no release notes at all on the net, not really serious work maybe they had issues translating from Chinese??? Using another HDD drive Does someone have other hints or a similar issue? Maybe it is neither the HDD nor the Mainboard/BIOS?

  • Formula to calculate probability of unrecoverable read error during RAID rebuild

    - by OlafM
    I need to compare the reliability of different RAID systems with either consumer or enterprise drives. The formula to have the probability of success of a rebuild, ignoring mechanical problems, is simple: error_probability = 1 - (1-per_bit_error_rate)^bit_read and with 3 TB drives I get 38% probability to experience an URE (unrecoverable read error) for a 2+1 disks RAID5 (4.7% for enterprise drives) 21% for a RAID1 (2.4% for enterprise drives) 51% probability of error during recovery for the 3+1 RAID5 often used by users of SOHO products like Synologys. Most people don't know about this. Calculating the error for single disk tolerance is easy, my question concerns systems tolerant to multiple disks failures (RAID6/Z2, RAIDZ3 and RAID1 with multiple disks). If only the first disk is used for rebuild and the second one is read again from the beginning in case or an URE, then the error probability is the one calculated above squared (14.5% for consumer RAID5 2+1, 4.5% for consumer RAID1 1+2). However, I suppose (at least in ZFS that has full checksums!) that the second parity/available disk is read only where needed, meaning that only few sectors are needed: how many UREs can possibly happen in the first disk? not many, otherwise the error probability for single-disk tolerance systems would skyrocket even more than I calculated. If I'm correct, a second parity disk would practically lower the risk to extremely low values. Am I correct?

  • How can I fix my vista PCs screen resolution and refresh rate

    - by Antony Scott
    I have a media PC running media portal hooked up to my HDTV via HDMI. The TV is a couple of years old now, so only supports 1080i, which is 1920x1080@25Hz. I've got it connected to my PC via a HDMI compatible AV receiver. If I power up the amp (wait for it to boot fully) followed by the TV| and finally the PC, all is well and I get a picture. If I deviate from that sequence, or don't wait for the amp to book up fully, or even switch the amp to another video input (for example, my PS3). The PC sees this and defaults the screen resolution/refresh rate to 1920x1080@60Hz. So, I end up with a blank screen. To fix this I have to use UltraVNC from a PC and change the refresh rate back to 25Hz. So, is there a way to turn off that auto detection, or to manually define what resolution/refresh rates the monitor can do. I'm using the on-board Radeon 3200 video and do not have any of the AMD software installed as it seems to cause problems with video playback. So, I'm looking for a native vista fix, or possible some 3rd party software.

  • ADO 2.8, VMWare and SQL Server - sudden bulk dropped connections

    - by CodeByMoonlight
    We have an overworked server currently running a single SQL Server 2000 instance on physical hardware, and about 40 different apps interact with it on a daily basis. Last year, the RAID controller failed and we had no spare, so IT Support hurriedly migrated it overnight to a copy running on a VMWare Server. While it was on that server everything ran much quicker due to it being a big improvement in spec. However, the biggest app using it had occasional serious errors which never occurred on physical hardware. Specifically, several times a week it would disconnect batches of users - anywhere from just ten to hundreds at once, and all at the same time. It didn't affect any particular users or PCs or offices - all were affected equally. The only common thing was the app, which is a VB6 app using ADO 2.8 to connect. The other apps connecting to that virtualised instance of SQL Server seemingly had no problems, although they were (and are) responsible for only a tiny fraction of the work involving this server. The upshot is that after about two weeks of loving the speed and hating the random mass disconnections (which we were never able to find a cause for), we sadly took the decision to return to physical hardware and the disconnections vanished. Now we've reached the point where the old server just can't handle all that's being asked of it, and we're intending to migrate everything to 2 or more other servers. The snag is that there's a good chance they'll have to be virtual ones again. Given what happened last time, I'm trying to find out what possible reasons there could be for these mass disconnections. We were running VMWare ESX, but the network is Novell-based. Also, the server had a linked server setup to connect to an Informix server using a known-to-be-buggy ODBC driver, and this is used throughout the day. Any ideas on the cause(s)?

  • Debugging "clogged" TCP connections

    - by Nikratio
    I'm having trouble with an internet connection that seems to randomly "freeze" arbitrary tcp connections. The connections stay established, but no data is coming through. When this happens, netstat still shows the connection status as ESTABLISHED on both the local computer: Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name Timer tcp 0 53 192.168.0.10:41129 173.255.235.238:143 ESTABLISHED 8219/gnutls-cli on (79.31/13/0) ..and the remote server: Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name Timer tcp 0 0 173.255.235.238:143 68.5.174.98:41129 ESTABLISHED 5303/imapd off (0.00/0/0) However, it seems that no data at all is transferred. If I run strace on the local and remote process, both just show a repeating sequence of select calls (with different fds of course), e.g. select(6, [0 5], NULL, NULL, {0, 50000}) = 0 (Timeout) select(6, [0 5], NULL, NULL, {0, 50000}) = 0 (Timeout) select(6, [0 5], NULL, NULL, {0, 50000}) = 0 (Timeout) The internet connection overall does not seem affected, I can still establish new connections to the same service on the same server without any problems. However, the affected local applications seem to be unaware of the problem and just hang. When I look at a packet capture of this connection on the client side, the last thing that happens is that the client transmits some data, then nothing happens for about 1100 seconds, and then several TCP Retransmission requests go out, with intervals increasing from 4 seconds to 130 seconds. No activity is captured after that. After about 10 minutes, the connection on the remote end disappears from the netstat (I wasn't able to catch any intermediate state), but still stays ESTABLISHED on the local end. Finally, after some more minutes, the local application aborts with a timeout and disappears from the local netstat output as well. Does anyone have a suggestion of how I could debug this further to find out where the problem lies and how to fix it? Additionaly and/or as a temporary workaround: is is there some way to globally reduce the timeout on client and/or server to reduce the time before the local application aborts?

  • Correct way to set up office network - 8 workstations, a file server and a staging server

    - by naunu
    Our office had this old school windows 2003 domain setup, our server caught fire, and now we are looking to do it right from scratch. Here is what we need: 5 PC and 3 Mac workstations for web development, they will each have WAMP/MAMP setup on them, managed by their developers. We will have a file server for assets, and a LAMP server with an external IP for staging. Here is what we have to work with: 5 IP addresses, brand new PC file server with windows 2008 SE, D-Link DSS-16+ 16 port switch, belkin 5 port wireless router, cable modem with 4 ports. How I have it set up now (this is a temporary makeshift setup): Cable modem = LAMP server, wireless router Wireless router = Switch = All of the workstations and file server (setup as a workgroup). We have noticed our internet is very slow with us all plugged in to the switch, and the switch plugged in to the router. I am not positive, but I think it is because our router does not have NAT. We are also having problems with the MACs connection to the network drive - it keeps disconnecting. I want this done right, and we have a ~$600 budget to buy anything else we need. Does anybody have any advice for me? Should I set up a domain or workgroup?

  • APACHE - PHP - Bounce emails

    - by user1179459
    I want to improve our mail server lists by handling all the bounces we get in our websites. I have a website which has over 8000+ users and another website which as over 1500+ users, they are emailed various notifications every second, ie. job alerts, email alerts, I am using POP connections with EXIM on APACHE server, most scripts are based on PHP language generates email on the fly. Problems i have But some users has registered long time ago and now quite few has bounce email address Some users register with dummy emails like [email protected] which never existed but a valid email address, any chance of stopping this without asking them login to the email account and clicking links which dont work most times.. (too annoying to the end user) Server is sending unnecessary emails can be avoided if i know they dont exists ? Solutions i need to have Is there a way i can download the bounce email list somewhere (WHM/Cpanel), i know exim mail has it but its not readable (i need a file like CSV or something similar to scan them over and write a php script to delete the users from the database ?) I need to know if there is any function in the PHP that can check the existence of the email address on the fly ? so that i can set the email send function in the mailer class to check before it sends out. On the server will bouncing emails are going to eatup lots of server resources ? like memory/cpu on processing them ? or are they are minimal where we dont have to worry about this at all ? May be a opensoruce or linux software to capture them and view them in a report basis and cleaning them up ? I am not a linux expert or server admin but i do lot of PHP coding, so please be descriptive of the solutions specially if they are linux commands Thank you!

  • Setting up Apache with multiple virtual host when using Plone 4.1

    - by Shaun Owens
    I have a Plone server running on CentOS, I have multiple instances of Plone running 4.0 and 4.1, I also have multiple sites. I am new to linux and haveing problems getting Apache to work with multiple virtuale hosts. The first host listed works just fine but the second host does not. I get the following error message when I start HTTPD: Starting httpd: [Mon Nov 07 14:38:31 2011] [warn] VirtualHost ordevel3.ucdavis.edu:80 overlaps with VirtualHost ordevel4.ucdavis.edu:80, the first has precedence, perhaps you need a NameVirtualHost directive.

  • Ubuntu 11.10 ATI Drivers vesa park

    - by Matthias
    This is probably not an issue, from all I can get it seems my hardware and drivers are properly installed. However when I go to system settings - system info - graphics. I get Driver: VESA:PARK. Experience: Standard. my graphics card is a: Ati Mobility Radeon HD 5470 512MB. I am pretty sure it's not a same-die GPU since there is a fan exhaust at the side of my laptop which I presume is the exhaust for the GPU... I have no clue whatsoever what this means. I installed the ati drivers first using the 'additional drivers' method. However I also decided to look a manual installation up via the terminal since I've had problems before with Ubuntu and ati cards. I used wget and something among the lines of sh dpkg -i. I can recall exactly, I took them from another stackoverflow answer. Anyway, it seems everything is installed properly since it shows up with these commands: sudo lshw -C video fglrxinfo however the first command seems to detect hardware, not the driver per se, although the driver is probably needed to detect the hardware anyway which would indicate its properly installed. I am still not sure about that VES:PARK thing though. I'd like to know what it means.. Also, if someone happens to know a good way of testing if the gpu is connected/being used...some sort of benchmark maybe...I'd like to hear it. P.s. I can find my way around in Ubuntu but I would probably still be considered a rookie by more experienced users.

  • Windows errors, how do I find root cause and fix it? Getting several errors

    - by Eric Martin
    My server is having issues and not responding to customer's https requests. I checked the event viewer and found several errors. These two are listed a couple of times: WINS encountered a database error. This may or may not be a serious error. WINS will try to recover from it. You can check the database error events under 'Application Log' category of the Event Viewer for the Exchange Component, ESENT, source to find out more details about database errors. If you continue to see a large number of these errors consistently over time (a span of few hours), you may want to restore the WINS database from a backup. The error number is in the second DWORD of the data section. And this one: An error occured while using SSL configuration for socket address 0.0.0.0:444. The error status code is contained within the returned data. SQL Server is not ready to accept new client connections. Wait a few minutes before trying again. If you have access to the error log, look for the informational message that indicates that SQL Server is ready before trying to connect again. [CLIENT: xxx.xxx.xxxx.xxx] I also found this in the event viewer but the computer has been restarted since this message and I have not seen it again. Configuring the Page file for crash dump failed. Make sure there is a page file on the boot partition and that is large enough to contain all physical memory. This is my virtual memory settings: I'm not familiar with WINS so I wasn't sure if that is where I start or how to resolve it. Is the WINS error causing the other problems or should I be looking somewhere else?

  • Exchange server intermittently not receiving or delivering emails to a few addresses?

    - by Gary Willoughby
    This is a strange problem. We are using an Exchange 2007 server to handle the emails to and from the company. There are two main problems which are probably related. None of our mails sent to one single customer are ever received. When we send any type of mail to one particular customer, they never get it. We have confirmed the address and tried to send more to other mail addresses on the same domain and they still don't receive it. No error (email or otherwise) is ever issued. (Domain related? Blacklisted?) Sometimes (intermittently) a mail sent to our company (can be any address on our domain) is never received. I tried this the other day from home and sent a mail to my work address. It was never received. But then a day later i sent another and it was received fine (so the mail address is fine). No error (email or otherwise) is ever issued. Any ideas where to start looking for causes?

  • Site to Site VPN problem, connection succesful data only oneway?

    - by Charles
    To start things off, I'm not the actual Administrator for the VPN Server, but he is also at a loss so I thought I'd ask it here. I know it's a Cisco ASA Firewall/VPN. I have a router that connects to the Cisco VPN server, it does so succesfully. I can ping everything within the remote network and from the remote network into my own. I've been able to SSH into a remote server over VPN as well, it all seems to work; until there's some more data returned. A quick example would be an internal webserver. The default homepage simply redirects, so only sends back HTTP headers with a "Location:". I receive this on my computer, but when I request the actual page then (which isn't that big) I don't get a response at all - it just stalls. And it does this for other services as well, for example SSH. I can do a couple of things while connected, but if there's more than xx output it seems to do nothing. The connection remains active throughout all of this. Has anyone ever experienced anything like this before / know what the problem might be? Another user who has a site-to-site connection with this VPN using the -exact same setup- has no problems, the only difference is that I have around 200ms ping to the VPN server/network because of a very long distance (other continent).

  • How to set up a VPN Incoming connection with Windows to tunnel Internet traffic?

    - by Mehrdad
    I want to set up a VPN on a remote server to route all my Internet traffic for privacy reasons. I can set up an incoming connection and connect to it successfully. The problem is, I can just see the remote computer and no other Web sites will open. I want the remote server to act like a NAT. How can I do that? Note that I don't want to split Internet traffic. I actually want to send all the traffic to the remote server but need to make it relay the traffic. For the record, my remote server is Windows Web Server 2008 which does not have routing and remote access service. Clarification I'm mostly interested in server configuration. I don't have any problems configuring the client. By the way, Windows Web Server 2008 seems to have the same VPN features built in client OSes (like Vista) and specifically, it doesn't include the RRAS console in MMC. I'm also open to suggestions regarding third party PPTP/L2TP daemons available, if they are free.

  • What could be causing SVCHost to leak handles?

    - by Goz
    I have a problem that has been causing me all sorts of grief recently. SVCHost appears to be leaking resources all over the shop. This is the SVCHost run with the arguments "-k netsvcs". At the moment it is sitting at around 5,700 Handles being used. Before I rebooted the machine it was sitting at around 33,000 handles! This higher number has been causing me large problems as my software, thus, fails to obtain the handles it needs (The software tries to create around 2000 handles). I'm totally at a loss as to what is going wrong. IF anyone could help me stop this happening it would be much appreciated. I'm running on XP with SP3. Edit: I tracked this problem down to the WMI system. I'm not sure why or how the problem was occurring. Basically I used "sc change" to move it into its own process and suddenly everything seems to be fine. I'm not entirely sure what is going on ...

  • Dynamic ARP Entries turning into Static ARP entries

    - by Zach
    I recently acquired a client that has a strange ARP caching issue on one of thier servers. I have a server that will eventually start turning it's dynamic ARP entries into static ARP entries. This causes problems because when the machine that has a static ARP entries on this server receives a new IP via DHCP, then the server is not able to communicate with the clients. Clearing the ARP cache resolves the issue and the server is fine for about a week and then it starts slowly turning ARP entries into static ARP entries. I haven't narrowed it down to when or how many it starts to do, but slowly you start seeing 1 static ARP and then 5 and then 10. The server in question is a Windows Server 2003 SP2. It is a DC, DHCP, and DNS server. I've checked the DHCP scope options and there's nothing in there that would indicate anything to do with static ARP entries. The only thing different between this DNS server and our other DNS server is that the 'Dynamically Update DNA A and PTR records for DHCP clients that do not request updates' is checked on the problematic server. I've done a bit of research about this and it seems that this may happen if any PXE type services are running, from what I can tell, there is nothing running a PXE server. I'm a bit lost as I have never seen dynamic ARP entries start to turn into static ARP entries. Right now my solution is a schedule task that runs every 24 hours to clear the ARP cache (arp -d *). I would like to not rely on this schedule task. Has anybody seen this before or have any suggestions on how to troubleshoot this?

  • The RTL8111/8168B NIC under Linux and the r8168 driver

    - by nik
    So I've got one of the infamous R8168 Realtek ethernet NIC, which have some problems under Linux. After some research, I found out I had to use the r8168 driver for this card (and not the r8169 which still loads when nothing else is available), which I did. So now everything works fine... Sort of. My download and upload rates are more than halved compared to what I should get. When I test (with eg. speedtest) I get something like 20M (often 15M) in download and 30M in upload, but if I test under Windows (everything is otherwise identical: same ethernet cable, same connection, at the same time of the day (well 5 min apart)...), I get 50M upload/download (which is what I expect). Where can it come from? Here's some info: ~ # lspci [...] 06:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

  • Very uneven CPU utilization with SQL Server 2012 on 2 processor computer with 16 cores / processor

    - by cooplarsh
    After installing SQL Server Enterprise 2012 with the Server + Cal license model, on a computer with 2 processors each with 16 cores (and no hyperthreading involved) and putting the server under extremely heavy load the 16 cores on the first processor were very underutilized, the first 4 cores on the 2nd CPU were heavily utilized, and the last 12 cores were not used at all (because of the 20 core limit for this sql server version). Total CPU utilization was displaying as around 25%. Unfortunately, the server suffered from extremely poor performance even though if the tasks were evenly distributed across the 20 cores it wouldn't have been anywhere near as bad. The Windows Server was running on a VMWare virtual image under ESX Server, but all of the CPU was allocated to the windows server. We tried changing affinity settings (e.g., allocating most cores to CPU and the others to I/O), but that didn't help solve the performance problems. Upgrading the product edition to SQL Server Enterprise Core 2012 not only allowed the SQL Server to utilize the 12 previously unused cores on the 2nd processor, but it also resulted in a much more even distribution of tasks across all of the processors. To get through the backlog of requests cpU utilization jumped to around 90%, and then came down to around 33% once it was caught up, but performance improved dramatically since we failed over to the newly updated version And the performance issues went away. I was wondering if anyone knows what might cause SQL Server to unevenly distribute the load, relying almost exclusively on the first 4 cores of the 2nd processor that had 12 cores idle, and allocate only a few tasks to each of the 16 cores on the first processor. Also, is there any way we could have more evenly distributed the load across the 20 cores that were being used without the product edition upgrade? The flip side of that question is what did the product upgrade do that caused SQL Server to start evenly distributing the load across all of the cores that it recognized? Thanks to any insight to answer these questions and/or links that might help me better understand how to make sense of what was happenings.

  • arp requests are sent continuously and my linux machine disconnected to the world

    - by sees
    I have the following problem and really need your help I'm implementing a small server to receive request from client on port 18999(just sample) using TCP socket. When I tested my server by using a lot of requests from a tablet through a router, I got the ARP problem(?) My net work just like: TABLET <------- WIRELESS ROUTER <------- MY SERVER (LINUX) Problems: 1. Can not connect to my Linux any more ( telnet, ping v.v...unreachable) 2. I use serial cable to connect to my Linux machine and use Wiresharp (from Windows) to catch the send message from Linux. It says that Linux keeps sending out continuously every 3 seconds ARP messages like the following: xx:xx:99:77:ff:69 ff:ff:ff:ff:ff:ff ARP 60 Who has 192.168.10.2? Tell 192.168.10.3 In the above message: xx:xx:99:77:ff:69 my Linux MAC address 192.168.10.2 my Tablet address 192.168.10.3 my Linux IP address Can you help me figure out the problem? Or tell me the way to detect the problem and reset the network back to normal (maybe restart Linux but I want to detect problem and restart automatically) UPDATE: 1. The above network works normally if tablet sends messages to my LINUX in normal speed (but also down after 48 hours) 2. The router works again after I unplugged my Linux ethernet cable (RJ45) from router. 3. The wireless network still works ( I can browser the router page from tablet) 4. When I use: ifconfig down then ifconfig up , the Linux restarts (?????????)

  • CIFS mounted drive setting "stick-bit" on all files, cannot change permissions or modify files

    - by mattmcmanus
    I have a folder mounted on an Ubuntu 8.10 sever through cifs that I simply cannot change the permissions on once mounted. Here is a breakdown of what's going on: All files within the mounted folder automatically have their permissions set to -rwxrwSrwx regardless of whether the file is create on the windows server or on the linux machine. I have the same directory mounted on two other linux servers (both running 9.10 instead of 8.10) with no problems at all. They all are using the same fstab options and the same credentials. //server/folder /media/backups cifs credentials=/etc/samba/.arcadia_cred,noexec,noserverino 0 0 I've I run a chmod command a million different ways, all of which report successfully changing the permissions. However it doesn't. The issue began after I updated from 8.04 to 8.10 Any idea why this may be happening on one machine? Since it started after an upgrade I'm not sure what is the bes thing to do. Any help you could give would great! None of my automated backup scripts are working because of this!

  • Why are SMART error rates going down?

    - by Jeff Shattock
    I have a hard drive that's part of a Linux software raid5 array. SMART has reported that its multi_zone_error_rate was 0, then 1, then 3. So I figured I better start backing up more frequently and prepare to replace the drive. Now, today, the multi_zone_error_rate of that very same drive is back down to 1. It seems that 2 errors unhappened while I wasn't looking. I've also seen simliar behaviour by inspecting the syslog on the server. Jun 7 21:01:17 FS1 smartd[25593]: Device: /dev/sdc, SMART Usage Attribute: 7 Seek_Error_Rate changed from 200 to 100 Jun 7 21:01:17 FS1 smartd[25593]: Device: /dev/sde, SMART Usage Attribute: 7 Seek_Error_Rate changed from 200 to 100 Jun 7 21:01:18 FS1 smartd[25593]: Device: /dev/sdg, SMART Usage Attribute: 7 Seek_Error_Rate changed from 200 to 100 Jun 8 02:31:18 FS1 smartd[25593]: Device: /dev/sdg, SMART Usage Attribute: 7 Seek_Error_Rate changed from 100 to 200 Jun 8 03:01:17 FS1 smartd[25593]: Device: /dev/sdc, SMART Usage Attribute: 7 Seek_Error_Rate changed from 100 to 200 Jun 8 03:01:17 FS1 smartd[25593]: Device: /dev/sde, SMART Usage Attribute: 7 Seek_Error_Rate changed from 100 to 200 These are raw values, not the human-useful values that smartctl -a produces, but the behaviour is similar: error rates changing, then undoing the change. None of these are the drive that had the multi_zone weirdness. I haven't seen any problems from the RAID; its most recent scrub ( < 24 hours ago) came back totally clean. The only thing I can think of is that the SMART reporting circuitry on the drive isn't working properly all the time. The cables are in tight on the drive and board. What's going on here?

  • MediaWiki migrated from Tiger to Snow Leopard throwing an exceptions

    - by Matt S
    I had an old laptop running Mac OS X 10.4 with macports for web development: Apache 2, PHP 5.3.2, Mysql 5, etc. I got a new laptop running Mac OS X 10.6 and installed macports. I installed the same web development apps: Apache 2, PHP 5.3.2, Mysql 5, etc. All versions the same as my old laptop. A Mediawiki site (version 1.15) was copied over from my old system (via the Migration Assistant). Having a fresh Mysql setup, I dumped my old database and imported it on the new system. When I try to browse to mediawiki's "Special" pages, I get the following exception thrown: Invalid language code requested Backtrace: #0 /languages/Language.php(2539): Language::loadLocalisation(NULL) #1 /includes/MessageCache.php(846): Language::getFallbackFor(NULL) #2 /includes/MessageCache.php(821): MessageCache->processMessagesArray(Array, NULL) #3 /includes/GlobalFunctions.php(2901): MessageCache->loadMessagesFile('/Users/matt/Sit...', false) #4 /extensions/OpenID/OpenID.setup.php(181): wfLoadExtensionMessages('OpenID') #5 [internal function]: OpenIDLocalizedPageName(Array, 'en') #6 /includes/Hooks.php(117): call_user_func_array('OpenIDLocalized...', Array) #7 /languages/Language.php(1851): wfRunHooks('LanguageGetSpec...', Array) #8 /includes/SpecialPage.php(240): Language->getSpecialPageAliases() #9 /includes/SpecialPage.php(262): SpecialPage::initAliasList() #10 /includes/SpecialPage.php(406): SpecialPage::resolveAlias('UserLogin') #11 /includes/SpecialPage.php(507): SpecialPage::getPageByAlias('UserLogin') #12 /includes/Wiki.php(229): SpecialPage::executePath(Object(Title)) #13 /includes/Wiki.php(59): MediaWiki->initializeSpecialCases(Object(Title), Object(OutputPage), Object(WebRequest)) #14 /index.php(116): MediaWiki->initialize(Object(Title), NULL, Object(OutputPage), Object(User), Object(WebRequest)) #15 {main} I tried to step through Mediawiki's code, but it's a mess. There are global variables everywhere. If I change the code slightly to get around the exception, the page comes up blank and there are no errors (implying there are multiple problems). Anyone else get Mediawiki 1.15 working on OS X 10.6 with macports? Anything in the migration from Tiger that could cause a problem? Any clues where to look for answers?

  • DD-WRT (WRT54G) and (THOMSON TG782) how to put them togather?

    - by FeRtoll
    Ok so let me explain, i bought WRT54G and successfully installed DD-WRT v24-sp1 (07/26/08) mini-special - build 9994. That's all ok no problems with it all normal functioning. And just to add (i don't need wireless, wireless is turned off always) What i want: ISP's router (TG782) from it's INTERNET port(out) cable "which was before in my pc" is connected to WRT54G's INTERNET port and then from WRT54G LAN port 1 to my pc. The problem: How do i connect and setup all? I have tried many times on many different ways but cant get it to work IF THE CABLE FROM TG782 IS CONNECTED TO WRT54G ON INTERNET PORT. If i connect the TG782 to Lan port 1 on WRT54G and my pc to lan port 2 then all works fine after i setup gateway and all. But i want to connect TG782 to Internet port of WRT54G because i need "Access Restrictions" and this only goes through WAN right? please correct me if i am wrong. What i have tried: This is how i have tried to setup all. The TG782 router ip is 192.168.1.1 And WRT54G ip is 192.168.1.30 so in WRT54G control panel i have setup like this: ----WAN Connection Type---- Connection Type: Automatic Configuration - DHCP STP: Disabled ----Router IP---- Local IP Address: 192.168.1.30 Subnet Mask: 255.255.255.0 Gateway: 192.168.1.1 (the TG782) ----Network Address Server Settings (DHCP)---- DHCP Type: DHCP Server Start IP Address: 192.168.1.100 Maximum DHCP Users: 6 And this wont work i probably miss something more, if anyone can help i would be thankfull. Also i have to note that i have tried to set my network adapter on pc to use the gateway of WRT54G and ip 192.168.1.102 In short: i cant get it to work normal only as a switch! Thanks for any help! -------EDIT:------- Here is an image which maybe can help: http://img27.imageshack.us/img27/4227/allin1w.jpg
