• How can I connect to my ACT database to export data?

  - by Adam Gessel

  I am trying to export data from an MSSQL server that ACT uses. It is ACT 2005. I have tried tons of different things, from trying to starting the MSSQL server in single user mode (still can't login), I have tried copying the mdf files from it and putting it on another server (it complains about having the same name as another database for master.mdf and almost every other file), I have tried putting Administrator in the group that the MSSQL instance runs under, and nothing seems to work! Can anybody with experience with this help me out? Thanks!

• Sonicwall with failover, multiple subnets, and preferred WAN interface per subnet

  - by Dan

  I am trying to set up my Sonicwall TZ-210 as follows: Two WAN interfaces (different ISPs), set up in failover mode. Two LAN interfaces with different subnets Each LAN subnet will have a preferred outbound WAN interface, but would failover when necessary. In this way, each ISP is being used for a separate subnet of my network, but both subnets could failover to the other ISP if their primary went down. I know how to do 1 and 2, but I don't know how to do 3. I could set up a route for each subnet to go through a specific interface, but what would happen in the event of a failover? Would it automatically update those routes? Thanks!

• Mysql performance problem & Failed DIMM

  - by murdoch

  Hi I have a dedicated mysql database server which has been having some performance problems recently, under normal load the server will be running fine, then suddenly out of the blue the performance will fall off a cliff. The server isn't using the swap file and there is 12GB of RAM in the server, more than enough for its needs. After contacting my hosting comapnies support they have discovered that there is a failed 2GB DIMM in the server and have scheduled to replace it tomorow morning. My question is could a failed DIMM result in the performance problems I am seeing or is this just coincidence? My worry is that they will replace the ram tomorrow but the problems will persist and I will still be lost of explanations so I am just trying to think ahead. The reason I ask is that there is plenty of RAM in the server, more than required and simply missing 2GB should be a problem, so if this failed DIMM is causing these performance problems then the OS must be trying to access the failed DIMM and slowing down as a result. Does that sound like a credible explanation? This is what DELLs omreport program says about the RAM, notice one dimm is "Critical" Memory Information Health : Critical Memory Operating Mode Fail Over State : Inactive Memory Operating Mode

• Mac OS X - rmdir fails with "Operation not permitted" for a folder created by a PC on a removable dr

  - by maxint

  Hello. I have a problem (using Mac OS X 10.5.8) with the access rights of a folder that was presumably created by a virus on a disk-on-key drive when I used it with a PC. I can't remove the folder or change it's name. In Finder's Info window the Lock box is unchecked and uncheckable - if I try to check it it flips back to off.

• forwarding packets from wireless nic wlan0 to another Wireless nic wlan1

  - by user179759

  I have two wireless interfaces wlan0, wlan1 I want wlan0 to be connected to the internet via a wireless router and I want wlan1 to be in AP mode acting as a router to give internet access to whoever connectes to it. So basically all packets coming through wlan1 should be forwarded to wlan0 = Router = Internet. That's including DNS/DHCP/etc.. [A]~~~~~(Wi-Fi)~~~~~~v [B]~~~~~(Wi-Fi)~~~> [me] ~~~~(Wi-Fi)~~~~~>[AP/Router]------->[internet] [C]~~~~~(Wi-Fi)~~~~~~^ Any idea how can I do this? ps: I tried using bridges but I always get 'operation not supported' using the brctl tool.

• Can snort output an alert for a portscan (sfPortscan) to syslog?

  - by Jamie McNaught

  I've been working on this for too long now. I'm sure the answer should be obvious, but... Snort manual: http://www.snort.org/assets/125/snort_manual-2_8_5_1.pdf lists two logging outputs on pg 39 (pg 40 according to Acrobat Reader) as: "Unified Output" and "Log File Output" which I am guessing the former refers to the "unified" output mode... which makes me think the answer is "No, snort cannot output alerts for detected portscans to syslog." Config file I've been using is: alert tcp any 80 -> any any (msg:"TestTestTest"; content: "testtesttest"; sid:123) preprocessor sfportscan: proto { all } \ memcap { 10000000 } \ scan_type { all } \ sense_level { high } \ logfile { pscan.log } (yes, very basic I know). A simple nmap triggers output to the pscan.log Can anyone confirm this? Or point out how I do this?

• Windows 7 won't load unless other harddrives "disconnect"ed in UEFI shell

  - by lmz

  I have three disks, one GPT partitioned containing Windows 7 and Debian, the other MBR partitioned containing CentOS, and the other one MBR partitioned, empty. It used to work (loading Windows boot manager using rEFIt) but now after installing CentOS and OpenIndiana on the second drive, Windows won't boot. The logo is displayed briefly and then a text mode scrollbar "Loading files", then back to the rEFIt menu. The only thing that makes it work is if I drop into the UEFI shell and run disconnect XX where XX is the device handle of the other hard drives (obtained from running devices). This makes me think that the bootloader is getting confused about where the Windows partition is. Is there any information on how the Windows UEFI boot loader finds the Windows partition, or is there any logging I can turn on to help troubleshoot this issue?

• Temporarily Utilizing 304 Header on Apache for Crawlers

  - by Volomike

  I have a client who has a hosting arrangement with 400 customer sites all hosted through SuPHP in CGI mode on Apache. The sysop is now gone and the client is calling on me for rolling out a new PHP thing. Trouble is -- server load is very high right now and we have found that it's due to the crawlers. We had one customer in particular who complained of slow websites, and we engaged a 304 header plugin in his site against most crawlers, and his site perked right up. We'd like to lower that load by issuing a global 304 header to all the crawlers, letting human visitors through. I have a long list of user agent keywords to trap for. What's the best way to temporarily engage that global 304 header, while allowing human visitors to get right on through? I mean, I could roll out 400 .htaccess file changes, but it would be ideal to make this change in like one central Apache config and then it automatically affect all the sites at once.

• Why aren't connections released by the tomcat AJP connector

  - by Chris

  I have here a jboss with a web application. The tomcat is configured to use the ajp connector. Incoming connections are tunneled via an apache reverse proxy to the connector. Now I recognized that under heavy load the connector keeps a bunch of connections in "keep alive" mode for eternity and doesn't release them any more. With the normal HTTP connector the app did well, but now with the ajp connector we have regular app stallments. Can someone give me some advice where to start to look to resolve this issue? Why does the connector not release the connection again after idling for 300 secs? thanks, chris

• Wireshark (WinPCap) does not see Intel X520-DA2 10 GbE NIC teaming intermittently

• Is this a common/bug on this PPPoE setting for Cisco ASA 5505?

  - by DCAlliances

  We have to change the way the firewall setup due to we've changed the internet provider. The way we setup we have ADSL modem and we have to do a full bridge mode and the firewall configuration has to change from Static IP to Use PPPoE option on Outside interface with PPPoE username and password, CHAP authentication, WAN IP and WAN subnet mask. [See the attachment] It's been working ok with the use of PPPoE option however the issue is that if we un-plug the power cable of the firewall. This "Outside" interface turned to blank - NO WAN IP, PPPoE username and password. So basically, we have to retype this information again. Is this common or a bug? Any ideas? Thanks

• IIS application pool and UAC

  - by rocku

  Hi, My system is Windows Server 2008 R2 with IIS 7.5. I need to run a site which is allowed to do some administrative tasks. I have created an AD user account and added it to all the required groups. The site's application pool runs with custom identity set to this AD account. This works, however some tasks fail with 'Access is denied'. I have found that it was caused by UAC (with UAC disabled everything works ok). So my question is - is it possible to run an application pool in elevated mode without globally disabling UAC? Possibly just disabling UAC just for this one account.

• Why doesn't the People Pane in Outlook 2010 show appointments for individual contacts?

  - by Curtis

  Outlook 2010 will not show appointments in the people pane. Under the activities tab if I go to All Items then eventually the appointments will show, but this takes a seriously long time. If I then click off the tab to look at another field then return to All Items, all the appointments are gone again. I need to be able to: Open a contact and see when that contact has appointments Open an appointment and see which contacts are attached to that appointment It works well from the appointment card to the contact, but has me completely frustrated going from the contact card to find the appontments. I have tried many things but cannot solve this problem. My set up is as follows: Exchange Server Windows 7 Ultimate Indexing enabled Cached exchange mode enabled Help! This is the whole reason I installed Outlook 2010.

• Can I drive two external screens from an 'Alu' iMac?

  - by robsoft

  I've got a 24" 2.4 Ghz Core 2 Duo iMac. It's about 18 months old, though I can't specifically remember when I bought it. It has a Displayport Mini-DVI socket on the back, and currently I have that linked to a DVI adaptor driving a Philips 20" widescreen monitor in portrait mode (awesome for browsing). I have another, identical Philips monitor and wondered if there was a way of connecting that to the iMac too. Is there such a thing as a DisplayPort Mini-DVI to dual-DVIs adaptor? Can this iMac's graphics card even drive such a set-up? The graphics chipset in the iMac is reported as ATI Radeon HS2600, 256 MB. The main iMac display is 1920x1200 and the Philips display is 1050x1680 (@60Hz, rotated 90 degrees). The third screen would be another 1050x1680 and ideally I'd have it portrait again, too. EDIT: Please let this question stand - it's not a dupe. The current Mac laptops use 'Mini Displayport' connectors, which are not the same as DisplayPort Mini-DVI connectors.

• Trying To Uninstall Exchange 2007 From Server - Stuck On "Mailbox Role Checks"

  - by Matthew Hodgkins

  Hi All, I am trying to uninstall Exchange 2007 on a secodary server which has been decommissioned for quite a while (cleaning up after an old Network Admin). The only roll the server had was "Mailbox Role" (the primary server also has this). I have tried uninstalling using Programs and Features GUI tool but that hung on Mailbox Role Checks. I then tried uninstalling Exchange by running Setup.com /mode:uninstall. It has been stuck on 1% of "Mailbox Role Checks" for over 3 hours now. Is there any other options I have for uninstalling Exchange 2007 so the old server can be removed from the Exchange Management console?

• Change smtp name

  - by Misterb

  Hello, My question is probably very easy to answer but I have been struggling with this the whole day. Actually, I would like to change my smtp.mail name and account that is shown as sending the emails in the header. I changed the "From" but it shows only in the "visible" part of the email and there are values that are different in the header. In this example : Received-SPF: pass (google.com: domain of [email protected] designates 67.221.174.127 as permitted sender) client-ip=67.221.174.127; Authentication-Results: mx.google.com; spf=pass (google.com: domain of [email protected] designates 67.221.174.127 as permitted sender) [email protected]; dkim=pass (test mode) [email protected] [email protected] account=bounce Thank you in advance!

• Changing location of ClamAV logging files

  - by GrumpyCanuck

  I've run into a weird problem with ClamAV that I have been unable to resolve, due to a incredibly non-informative error message. I've installed ClamAV via aptitude on an Ubuntu box (ClamAV 0.96.5/13202 according to the system) up on EC2 and it is 100% stock. We have an additional drive mounted under /mnt where we put all our log files. When I start it up with the log files in the default location, it runs just fine. However, if I change the configuration file from /var/log/clamav/clamav.log to /mnt/clamav/clamav.log I get the error ERROR: Can't open /mnt/clamav/clamav.log in append mode (check permissions!). ERROR: Can't initialize the internal logger It's the same file with the same permissions on it, just in a different location. Any thoughts or tips on how to resolve this problem would be greatly appreciated.

• ZFS SAS/SATA controller recommendations

  - by ewwhite

  I've been working with OpenSolaris and ZFS for 6 months, primarily on a Sun Fire x4540 and standard Dell and HP hardware. One downside to standard Perc and HP Smart Array controllers is that they do not have a true "passthrough" JBOD mode to present individual disks to ZFS. One can configure multiple RAID 0 arrays and get them working in ZFS, but it impacts hotswap capabilities (thus requiring a reboot upon disk failure/replacement). I'm curious as to what SAS/SATA controllers are recommended for home-brewed ZFS storage solutions. In addition, what effect does battery-backed write cache (BBWC) have in ZFS storage?

• page allocation failure - am I running out of memory?

  - by mfriedman

  Lately I've noticing entries like this one in the kern.log of one of my servers: Feb 16 00:24:05 aramis kernel: swapper: page allocation failure. order:0, mode:0x20 This is what I'd like to know: What exactly does that message mean? Is my server running out of memory? The swap usage is quite low (less than 10%), and so far I haven't noticed any processes being killed because of lack of memory. Additional information: The server is a Xen instance (DomU) running Debian 6.0 It has 512 MB of RAM and a 512 MB swap partition CPU load inside the virtual machine shows an average of 0.25

• Mysqldump causes "Too many connections"

  - by vbachev

  A scheduled backup using mysqldump on one of our databases is causing Too many connections. The database is of both InnoDB and MyISAM tables with size of around 500Mb. The Too many connections appears for about 2-3 minutes We understand that mysqldump locks the tables and causes all other queries and connections to pile up and jam the mysql server. We need frequent backups and we cannot afford server downtime or putting websites in maintenance mode while doing it. Our websites are global and traffic is high all the time so its hard to find a moment for backups. How can we avoid downtime during backups?Is there maybe a way to use mysqldump in way that it will not lock all tables at the same time?Is there an alternative to backing up with mysqldump?

• How to SSH to guest ubuntu OS in vmplayer4

  - by Grace

  I have installed vmplayer4.0.4 on Windows7, and install ubuntu12.04 as Guest OS. Basically i have two problems: Default vmplayer use NAT for network access. I could ping the guest OS from the Host OS. But how could i access the Guest OS from outside the Host OS? If i change to Bridged Mode, sure the Guest Ubuntu OS could get DHCP ip in the same subnet as Host OS. But i could not ping the Guest OS from the Host OS, or vice versa, even if i disable the iptables firewall on Ubuntu Guest OS like following: iptables -F iptables -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X iptables -P INPUT ACCEPT iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT I could not figure it out, could anyone help on this issue? Thanks in advance.

• Everything Windows Explorer does hangs up t some time or another

  - by William Barnes

  Yes this is a duplicate of something I have tried to ask in the past. I think I am posting wrong since my first question was deleted OK I ran SCANNOW nd it came back with no problems. I booted in Safe mode and windows evplorer worked OK. I am not sure what that proves. I also ran AUTRUNS and disabled everything that you said, but it still dies. I read someplace that it could be a service program, but I can't find that link anymore. Something about shutting off all non-windows SP's and then start adding back SP's until it quits. The problem is that sometimes it will work, but most of the time it does not. Makes saving or retrieving anything impossible. SAVEAS hangs up, my Garmin Map updater hangs up etc.. I was having this problem before installing Garmin so I am reasonably sure it is not the problem HELP PLEASE, I don't have many brain cells left and can't afford to lose more.

• How can I dual boot a UEFI OS and a legacy boot OS, or convert stock Windows 8 to BIOS?

  - by The Great Widi

  I have a computer (HP Pavilion g6-2342dx) which came with Windows 8, and thus the new UEFI boot system. I would like to install a few OS's which are not EFI compatible, and Arch GNU/Linux with BIOS mode. However, I would not like to completely wipe all my files to set to legacy. My preferred options would be to: 1. Multiboot legacy OS alongside my EFI os 2. Convert Windows 8 and Ubuntu to legacy without reformatting or switching to MSDOS part table. If anyone could suggest a solution or a method, your help would be appreciated! Thanks!
