• SQL log shipping for reporting

  - by Patrick J Collins

  I would like to create a read-only copy of my SQL Server 2008 database on a secondary server for reporting and analysis. I've been testing log shipping, configured to run every 5 minutes or so. Alas, there appears to be a stumbling block, for exclusive access is required on the target database during the restore, which in turn requires killing all active connections. This is far from ideal, especially if a user is in the middle of running a report. Any better suggestions? Edit : I'm doing this on the Express edition.

• What are the pros/cons of blocking a program from running in %appdata%, %temp%, etc.?

  - by poke

  While researching ways to prevent CryptoLocker, I saw a forum post that advised using Group Policy Objects (GPO) and/or antivirus software to block run access in the following locations: %appdata% %localappdata% %temp% %UserProfile% Compressed archives Obviously, anything written in a forum should be taken with caution. I do see advantages to do doing this, though, primarily because malware likes to execute out of these locations. Of course, this could impact legitimate programs as well. What are the drawbacks to blocking run access to these locations? What are the advantages?

• .NET Mailserver smtp/relay problem

  - by Quandary

  Question, I'm trying to setup my own mailserver: This is the server (latest version): http://www.codeproject.com/KB/vista/SMTP_POP3_IMAP_server.aspx Now I've the following problem: I can add user accounts, and receive mails from the internet in that account. I can also setup a mailinglist. This works fine (for local users). But I can't send any emails out... Why ? I've forwarded port 25 + 110, and it works fine for receiving mails from the internet. Do I need to configure SMTP under SMTP, or under relay, or both ? Or do I miss anything ?

• How can I track down what part of pfsense is blocking website access?

  - by Chase Florell

  I've got a PFSense firewall/gateway on our network. Everything works great except for the fact that I cannot access one specific website. Pfsense is running the following packages Country Block LightSquid nmap notes squid squidGuard Strikeback I can access every single website I've ever tried aside from one that we need for business use (http://bridalnetwork.ca) here's the traceroute frodo:~ chase$ traceroute bridalnetwork.ca traceroute to bridalnetwork.ca (192.197.103.73), 64 hops max, 52 byte packets 1 rohan (192.168.5.1) 6.618 ms 1.662 ms 9.207 ms 2 * * * 3 * * rohan (192.168.5.1) 7.225 ms !H 4 rohan (192.168.5.1) 5.314 ms !H 5.701 ms !H 7.573 ms !H frodo:~ chase$ How can I figure out what the reason behind the blockage is? note: this has been tested on every computer on the network with the same results. ps: the pfsense box is 'rohan' (192.168.5.1) Here's what I get with Squid enabled and here's what I get with Squid disabled

• tool for monitoring network traffic on Windows 7 Home

  - by Xah Lee

  for Windows 7 Home Edition: can anyone recommend a tool to monitor network traffic? either build-in or 3rd-party. I like to have a graph view (e.g. as in Task Manager) but also nice are tool that lets me see what IP/port that's incoming/outgoing. Command line is fine. Or even some tutorial. Thanks. (am old unix sys admin and web app dev. Though not much of a network admin and don't know much Windows. I need this tool just for my home PC, not in any pro capacity.)

• How can I switch between the HDMI and DVI outputs of my graphics card?

  - by Owen Melbourne

  I've got an Nvidia GTX 560ti card which currently I've got my 2 monitors hooked up to using the 2 DVI ports. However its got a mini-HDMI port which I've plugged a HDMI cable in (with mini adapter) and lead it into my TV which is across the room. I'm hoping to be able to toggle between the HDMI output and the DVI outputs, however I'm not sure how I'd go about this, Could somebody please point me in the right direction, I'm not really worried about having all 3 on at the same time so that isn't a problem, but if its possible then I'll do that.

• 3 monitors + a TV on a single card with Eyefinity?

  - by Paul Accisano

  Greetings all, Right now I have a fairly standard video card with 2 DVI ports, one powering my single monitor and another powering my HDTV (with a DVI-to-HDMI cable), which are in separate rooms. I never need to have my monitor and TV active at the same time. I'm looking into a possible computer upgrade. I'd like to know if the following situation is possible. I want three monitors on my desk powered by a single card, which I hear these new Eyefinity cards are capable of. But, I also want my TV hooked up. At any given time, I would want either my three monitors active or my TV active, never both at once. So it seems to me it might be possible to do this all a single 3-port card with a splitter of some kind. Is this possible? What hardware would I need? Thanks!

• Locking down a box on the web

  - by glowcoder

  I'm a Java developer who is looking to put a game on the web. I'm not much of a web or server guy, though, and frankly I seem a little lost at where I should start with putting something on the web. My application works fine on my machine, and I'm sure I can make it work fine on any box I put it on. But the security of that box is pretty important. If I sign up for a standard hosting package (let's say from GoDaddy or something) can I simply tell them "make port 12345 open for communication" and let them handle the rest of the security details? If I can't, what are the things I'm going to need to know to prevent my game server from getting hacked to shreds? (Links to solid resources fine by me!) Thanks!

• Belkin Flip KVM keyboard skip problems

  - by Craig

  I have just bought a Belkin Flip 2 port KVM. Functionally it is almost there except I have a keyboard sticking problem. So if I type the word 'Hello' it will often (about 25% of the time) output 'Hellooooooooooooooooooooo'. If I plug the keyboard directly into the USB on the computer I don't have this problem, only when plugged into the KVM. I feel like it is a USB speed problem. Followup It appears I have the same problem with the mouse, it will jump from one side of the screen to the other as I move it. The mouse is annoying but half as much as the keyboard.

• Workaround to extend limited screen real-estate on Windows?

  - by Brian

  I need a means to use a software tool that requires at least 900 pixels of vertical resolution (as in, the "OK" button to save settings won't be reachable on smaller displays) on a laptop/projector with only 768 pixels of vertical resolution for a training session. So far the only workaround that's been suggested is to memorize the number of tab stops to reach the "OK" and "Cancel" buttons. Any suggestions on a better workaround? What I'd like to see is a utility that would let me treat the physical display as a 1024x768 view port into a larger, virtual display area. Does anything like that exist? Anything else that might help?

• Writing your own Makefile for OpenBSD ports

  - by The_dude_man

  I have an OpenBSD box running Python 2.6. I want to install py-setuptools, but that package is built against 2.5. I was curious as to what the Makefile for py-setuptools [Someone with rep, fix me please][http://www.openbsd.org/cgi-bin/cvsweb/ports/devel/py-setuptools/Makefile?rev=1.13;content-type=text%2Fx-cvsweb-markup ] looks like, to see if it mentioned anything about Python 2.5 as a dependency. I did not find anything version-dependent. I typed make install in /usr/ports/devel/py-setuptools on a whim, and it blew up because of failed missing Python 2.5 dependency. That is expected. My question is, How do I modify the Makefile to build against Python 2.6 ? I came across this in the man pages [please fix me][http://www.openbsd.org/cgi-bin/man.cgi?query=port-modules&sektion=5&arch=&apropos=0&manpath=OpenBSD+4.6#CORE+MODULES] , but I am still clueless how to specify what version to build against. Also, I dont see anything that actually installs the egg.

• Sun Grid Engine: Automatically Terminating Idle Interactive Jobs

  - by dmcer

  We're considering using Sun Grid Engine on a small compute cluster. Right now, the current set up is pretty crude and just involves having people ssh to an open machine to run their jobs. We'd like to allow interactive jobs, since that should ease the transition from manually starting jobs to starting them using qsub. But, there is some concern that, if we do, people might accidentally leave their interactive sessions idle and block other jobs from being run on the machines. The issue isn't just theoretical, since we previously tried using OpenPBS and there was a problem with people opening up an interactive job in a screen session and essentially camping on a machine. Is there anyway to configure SGE to automatically kill idle interactive jobs? It looks like this was requested as an enhancement (Issue #:2447) way back in 2007. But, it doesn't seem like the request ever got implemented.

• Huawei b260a gsm modem not forwarding gre for pptp tunnel

  - by Priit

  I have a huawei gsm modem that does not want to let gre through. The goal is to connect into a pptp server thats behind the huawei. In the modems port forwarding settings theres a ready made profile for pptp (1723). After activating that the MS pptp test tools show that connection is being initiated but no gre packets make it to the server. After taking a closer look into the modems iptables rules theres nothing in there about gre. So I tried making gre rules manualy into forward and preroute chains without any success what so ever. As far as I can tell theres no ip_gre module present on the device is that needed for gre forwarding? Thats what I'm afraid of that it doesn't support gre in NAT but how would I turn it into a bridge? The wan interface is ppp0 so bridging it with eth0 would not work right? Is there some iptables rule I could use to make the modem let all the traffic just straight through?

• Dell XPS 420: Turning computer on, video ports showing static

  - by Roy Rico

  I have a Dell XPS 420 which i recently upgraded with a EVGA GTX 550TI and a 80GB SSD Drive. I converted this machine into a home theater PC. Which I've always had on. The computer wasn't responding, and so i restarted it and when it started, video ports showing static. I was getting static on my TV thru both DVI ports and the mini HDMI port. I assumed my video card had gone bad, but i completely replaced it and still the same behavior is occurring. I do not know how to diagnosis this issue. Any thoughts?

• Forcing logon to Air Watch server upon joining wifi

  - by DKNUCKLES

  I'm setting up a wireless controller that I would like to leave as unsecured. When a user connects to this network they need to be forwarded to a specific page where they can authenticate with the Air Watch system they have in place. Once authentication takes place, a profile will be downloaded to their device and we can administer the devices accordingly. I'm mulling over how I can force the page to the user when they log in. The methodology I'm thinking about working with is creating a NAT rule for that VSC that would forward all port 80 and 443 traffic to the airwatch server. Once they authenticate, a profile will be downloaded which will connect the devices to an Virtual Access Point who's SSID isn't broadcasted. Is this methodology correct or can someone think of an easier / more efficient way of accomplishing this? The controller is an HP MSM720 for what it's worth.

• Not able to connect to a mac client from a windows machine

  I have a Server.exe file which I use to connect to a mac.(I am fairly confident that server.exe is not buggy ).When i try to do this I get this often cited error "No connection could be made because the target machine actively refused it " I did search some existing questions about this on the forum and it looked like this might be a firewall issue.FWIW I dont have any firewall set on my mac (client) and on my server machine (Windows 7 64 bit ) under the firewall settings I have :- Incoming connections : Block all connections to programs that are not on the list of allowed programs. Active Domain Networks: Same domain as the one which my client is on. Windows Firewire State: Off. Do you think i need to change something here?Can someone help me with next steps?

• tcpdump selective acknowledgements question

  - by wlaus

  Hi All, I eventually sometimes watch most initial tcp connection attempts like this: tcpdump -nn -Z somepcapuser not src host (12x.x5.109.xxx or 62.75.160.xxx ) and not (port 9001 or 443 or 8080 ) and tcp[tcpflags]&(tcp-syn) !=0 and not tcp[tcpflags]& (tcp-ack) !=0 or icmp this works pretty well to quickly identify oddness so far. However, I now have a question on the following output: 03:53:52.227884 IP 203.81.166.20.53786 62.75.160.xxx.80: S 846930886:846930886(0) win 61690 "<"mss 1460,nop,nop,sackOK,opt-178:f04700000000,nop,wscale 4"" I wonder what the marked portion means, haven't seen that before.

However I'm wondering if it's possible to do this alongside HTTP, so that i do not need another server{} section which would just be a replication of the http section.
