• Screen scraping software that will traverse pages

  - by nilbus

  We're creating a mashup site that pulls information from many sources all over the web. Many of these sites don't provide RSS feeds or APIs to access the information they provide. This leaves us with screen scraping as our method for collecting the data. There are many scripting tools out there written in different scripting languages for screen scraping that require you to write scraping scripts in the language the scraper was written in. Scrapy, scrAPI, and scrubyt are a few written in Ruby and Python. There are other web-based tools I've seen like Dapper that create XML or RSS feeds based on a webpage. It has a beautiful web-based interface that requires no scripting skills to use. This would be a great tool, if it were able to traverse multiple pages to gather data from hundreds pages of results. We need something that will scrape information from paginated web sites, much like scrubyt, but with a user interface that a non-programmer could use. We'll script up our own solution if we need to, probably using scrubyt, but if there's a better solution out there, we want to use it. Does anything like this exist?

• Vista logs into black screen, "Application Error 0xc0000022" for explorer.exe

  - by IMAPC

  Whenever I attempt to log into a Windows Vista computer (the only account on it), I'm presented with a black screen & a cursor. I can open Task Manager, and from there I can launch applications. It seems to be using Aero Basic (instead of the full Aero which I had set as default before the problem started). When attempting to launch "explorer.exe" I get "explorer.exe - Application Error 'The application failed to initialize properly (0xc0000022). Click OK to terminate the application.'" Every now and then I get an error along the lines of "the application has failed to start because its side by side configuration is incorrect please see the application event log for more detail." I can boot into safe mode successfully, but I still get the black screen when I log into it in regular mode. I've tried most of the suggestions here, but did not work. I'm attempting to back up everything right now in case the only fix is to reinstall Windows. Has anyone seen this before?

• Hide account from login screen but can be used in UAC

  - by tvanover

  So I have a Windows 7 home machine with 2 user accounts. One is a standard user account and one is an administrator account. Now this is going to be put in the hands of a very low-tech user so I don't want them to be able to see the administrator account on logon, but they want to have a password to prevent someone else from using the machine. My goal is that when the user turns on the computer, they are presented with their login. After logging in to their non-administrator account, if something needs to be installed then the administrator account can be used through UAC. I have tried creating the reg key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList and adding a dword of the account name and set it to 0. It succeeded in hiding the account from th login screen. As well as hiding it from UAC. So it fails the second requirement, of being able to run things as administrator through UAC. Also since I didn't set an administrator password (left it blank) it seems that I have completely locked myself out of the machine since runas doesn't accept blank passwords. So I also cannot undo it, and have quite effectively bricked the install, prompting an OS reinstall. This is Windows 7 Home, so there is no Users management console.

• DNS Piority in home-use Routers

  - by DucDigital

  Force DNS on router instead of ClientSide DNS like OpenDNS or GooglePublicDNS Im trying to implement some site blocking using DNS, the hardware is simple Routers like Linksys and Netgear that you use in house for family purpose. Currently I tried to set a computer to opendns, while my router set to something else, when check using opendns.com/welcome, the computer is identified as opendns. and Vice versa, this time the computer didn't identified as opendns. Is it posible to force user to use our DNS instead of their setting DNS?

• Home CAT6 wiring: CMR vs CMP?

  - by Eddie Parker

  I'm planning on wiring my house with CAT6 cable. I'm finding a large jump in price between CMR and CMP cabling, and I'm confused by what counts as a 'plenum' and what does not. As I'm wiring my house, I'm planning on going through interior (hollow) walls, and through the attic and crawlspace to get to the points I wish to wire. I will be going between floors at one point, which leads me to believe I need at least CMR, and obviously CMP wouldn't hurt either. I don't mind spending the extra money if I need to, but is it overkill going for CMP if the bulk of the wires are either going vertical, or through a crawlspace or attic?

• Ripping a home video VCD on Linux or Windows with VLC or otherwise

  - by user259774

  I have a VCD with 22 minutes of video on it. I would like to retain this footage and throw away the VCD. I can play the whole thing with VLC ("open disc - vcd - /dev/sr0 - play"): all 22 minutes of the main track. I don't believe there's any other content aside from the main track. I can seek to anywhere I want to within the 22 minute track. If I mount /dev/sr0 /media/vcd and then try to copy the only file from the MPEGAV folder, I get an I/O error, with an empty destination file. VLC has a "convert" option in addition to "play". When I use this I actually get a good OGG file back, after it runs through the video in painful real-time. I guess it dubs it frame-by-frame. But the file is only 10 minutes long, leaving 12 minutes off of the track. Handbrake doesn't detect it's track titles, unfortunately. I don't know if I should start getting involved with GNU ddrescue or if it's because VCDs somehow encode their data sectors differently. Anyway, I'm in way over my head and if anyone knows how I could get that video track off the thing, feel free to share! Edit: I should note that I also have access to a Windows computer

• Looking for a list of compatible chipset, mobo with Windows Home Server/Windows 2003

  - by ronaldwidha

  I'm building a WHS and looking into finding a mini atx mobo for Pentium E5300 socket 775. I have a couple of mobo in mind and would like to check them against a list of compatible mobo/chipset with WHS/WIndows Server 2003. I've found http://www.windowsservercatalog.com/ but unfortunately it doesn't contain any mobo/chipset. Anyone know of such compatibility list?

• Multiple home routers

  - by netvope

  Suppose I have the following configuration: Router A: WAN port connected to the Internet, LAN = 192.168.1.0/24 Computer A: Connected to router A as 192.168.1.101 Router B: WAN port connected to router A as 192.168.1.102, LAN = 192.168.2.0/24 Computer B: Connected to router B as 192.168.2.101 Now I want computer A to communicate with computer B seamlessly (e.g. can establish a TCP connection by running nc 192.168.2.101 <port>) by means of routing, rather than merging the two networks into one (which can be easily accomplished using router B as a switch). Most routers are shipped with NAT turned on, of which I definitely need to turn off in router B. But what other steps do I need to take so that packets from computer A to computer B would go through router B? I could manually add a routing table entry in computer A so that all packets targeted to 192.168.2.0/24 go through gateway 192.168.1.102, but I would prefer an automatic way if it exist.

• Black Screen and System Hang - Possibly CPU overheating

  - by Mahesh

  I have this old computer - P4 2.0ghz, 1.2GB RAM and onboard graphics(no external card), 80GBHDD. It has xubuntu installed on it and it regularly hangs when it takes more system resources for say like graphical programs, too many tabs on firefox etc. It just either hangs the system or shows black screen. Tested if it was issue of HD but it wasn't because i have used linux livecd and problem is still the same even if I have removed the HD. I have also tested with USB linux (puppy linux and ubuntu linux on 8gb drives). Tested windows XP as well on this HD and results are the same. Tested another HD on this machine, results are still the same with it. System hangs or goes black screen and requires restart. I thought later it could be thermal heat issue and then applied thermal paste on heatsink but still it fails to work for me. It continues to show symptoms. Another thing which was yet to be tested is changing of CPU fan which was not done because I have not found any fan for old pentium 4 machine in the market. I have to hit online stores (but i am in india and it's hard to find it in online shops which can deliver it to me). So far I don't see this as HD or Monitor or OS issue because I have tested with other HD and results are the same. So it could be either CPU fan or motherboard? What could be possible issue with the hardware?

• Windows 7 and Vista Home Networked-Unable to login from Vista to Windows 7

  - by Lynn

  I set up both Vista and Windows 7 on the same workgroup. I can view Windows 7 from Vista and vice versa. I can login into Vista from Windows 7. I am unable to login to Windows 7 from Vista. When I enter the Windows 7 User name and Password on Vista, the following information appears: Logon unsuccessful: Windows is unable to log you on. Be sure that your user name and password are correct. Both are correct. Do you have any idea how I can resolve this logon issue? Thank you, Lynn

• Networking Home Office

  - by Matt

  I'm in the process of building an office in my garden. It's about 25m away from my house. I'd like to run a wired network connection to the office. I'd rather not go down the powerline route, as speeds don't seem great, and I'm likely to want to be moving a lot of data around on the internal network. I have an electrician who is running armoured electrical cable to the office, and is providing conduit for me to run network cable. My questions are: 1) What type of cable to run 2) How I terminate/connect it at both ends I could get something like armoured cat6 utp solid core (like this: http://www.netstoredirect.com/cat6-cable/289166-external-armoured-cat6-utp-solid-cable-price-per-metre.html) which seems fairly robust, but then I have to terminate it. Additionally, where the cable enters my house, there is about another 15m to where my router is situated. I also read this artice: http://www.audioholics.com/audio-video-cables/bjc-cat-network-cable-quality-interview which scared me into realising I don't know what I'm doing!! particularly with termination. Or I could get an "cat6 external patch cable" (e.g http://www.netstoredirect.com/rj45-network-cables/239231-external-cat6-utp-ldpe-rj45-patch-leads.html) and run that in the conduit, and work out how to terminate it at the house end. At the office end I guess I can just plug it into a switch. Any help? Thanks

• iRedMail home setup - use different SMTP relay for different destination domains

  - by John

  Hello helpful server folks, I'm messing with iRedMail. I've mostly been successful, I think I have an SMTP problem. I have changed RoundCube (webmail) to use BrightHouse's, my ISP's, SMTP server for outgoing. It works fine, I click send and poof, I have gmail. I can reply from gmail to my email server, and it works. It took 10 hours for the email to show up, which is a different problem, I think, but it does work. But when I send from my server TO my own server, my ISP's Postmaster account sends me a cryptic blurb. I just got off the phone with them, and they say it "should work", and that they can't reach my pop3 server. (pop3, pop3s, imap, and imaps are all open on my router and forwarded to the server, I'm not sure what I need, I'm just covering my bases...) pop3 and/or imap as external interfaces are just formalities, I really just want webmail to work. Roundcube only takes one SMTP server in its configs. How can I configure Postfix to relay / forward emails to my ISP's SMTP, while taking messages bound for my own domain and processing them? Since my ISP won't let me "bounce" my emails off of it. Maybe I'm vastly misunderstanding how e-mail works in general: To receive mail, I should only need port 25, SMTP, open to the internet, correct? Should I be concerned about some authentication failure from the outside to my relay? (My relay requires user/pass to use, my ISP's requires none.)

• Dual Home HP Server running Win2003

  - by Colm

  Hello everyone. I'm new to server dual homing. I have a HP ProLiant DL360 G4p running Win2003 with 2 NICs , only one is currently active. I'd like to activate the 2nd NIC connected (in a active/passive state) to a 2nd switch with only one IP address and ideally only one mac layer address. The 1st switch is a Cisco 2960G and the 2nd is a Cisco C3560G. There are VLANS, RSTP and PAGP in use already. Can someone give me an idea, in broad terms , of what technology/protocols I should be investigating (HSRP, SLB Teaming etc.) ? I can provide more info if needed. Thanks, Colm.

• I can't externally access my home server's wordpress website

  - by piratepartypumpkin

  Basically, I can access everything just fine using 127.0.0.1, but if I use my external IP (123.123.123.123), I get page not found. My router is port forwarding HTTP port 80 to port 8080 on my servers internal IP address. In other words: (Application: HTTP | Start: 80 | End: 8080 | Protocol: Both | IP Address 192.168.0.101 | Enable [YES]) I know it's forwarding properly, because when I stop port forwarding, I can access my router page by using my external IP. My virtual hosts file is: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /opt/lampstack-5.3.16-0/apps/wordpress ServerName example.com ServerAlias www.example.com </VirtualHost> and my httpd.conf file is: Listen 80 Servername localhost:80 DocumentRoot "/opt/lampstack-5.3.16-0/apache2/htdocs <Directory /> Options FollowSymLinks AllowOverride None Order deny, allow deny from all </Directory> <Directory "/opt/lampstack-5.3.16-0/apache2/htdocs"> Options FollowSymLinks AllowOverride None Order allow, deny allow from all </Directory>

• iBook G4 has black screen on boot

  - by Jonathan Patt

  I have an old iBook G4 (A1054, 1.2 GHz) which has issues when it loses power or is shut off. If the battery drains—which happens quickly, as its remaining capacity is very low—it enters some sort of weird mode where it's not really awake (the screen is black, can't do anything) but it has no pulsing light indicating it's asleep either. The only way to exit this mode is to hold down the power button for ten seconds until it shuts off, and attempt rebooting it. Almost always, however, it makes the sound of the optical drive starting up, and then doesn't continue past that point. The screen doesn't come on, and things like resetting PRAM don't work. Occasionally a fan comes on loudly for a second or two. This sometimes seems to correspond with my pressing down on the rear-right casing, above the power jack. In the past, shutting it off, disconnecting it from power, removing the battery and waiting for 30 minutes would do the trick, but this time I have done that several times, letting it sit for up to several hours before retrying, to no avail. Any ideas?

• online backup plan for a home office with servers

  - by TiernanO

  So, i am in the process of tweaking my spending and i need to change my backup plan... I am currently using a mix of JungleDisk and ZManda ZCB to backup files on my MacBook Pro, Main Windows Server Wrokstation, a dedicated Windows Server in a datacenter, and various other machines and file sources. The problem is the cost: this month, it has cost me about $90 to backup a little over 500Gb... This amount of data will increese over time too, since i am backing up Photos (24Mb RAW images + 4-8MB JPEGs), Videos (various cameras shooting 720p and 1080p), Music, Movies, TV shows and Apps from iTunes (though with iTunes cloud, this might not need to be backed up again) and source code... I have looked at the likes of Mozy, CrashPlan+ and Pro, Backblaze and Carbonite, but each have their problems: Mozy seems overly expenvice per gig at 50C Crashplan wont sell to me since i am outside the US (they hide it on their site... hidden in the FAQ section!) Backblaze dont support Windows Server Carbonite business pricing is $600 up front for 500Gb of storage... Fro $229, they will not backup Windows Servers. So, other than those, Jungle Disk (at 15c per Gig) or ZManda (also at 15c per Gig) what other options are there? what are other people using?

• 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?

• Menu command stuck on screen

  - by 280Z28

  For some reason, periodically when I select a menu command, the command label gets "stuck" on the screen and won't go away. I can close all open applications, including whichever one I was using when it got stuck, but it still won't go away. In the screenshot below, I opened an new instance of IE just to show how the label stays on top. The label was not created by this instance of IE. Edit with the source: The label that gets stuck is the first menu command I select in IE. If a label is already stuck, a new one does not get stuck (regardless of which instance(s) of IE are involved). Based on this knowledge, I now just open IE on my secondary monitor, carefully open the context menu so the Properties command is in the bottom corner, and click it. This is not a solution... The label never moves and is transparent to mouse input (if I click it, it's as if I clicked the item behind it). The label does not go away if I close all running applications. I haven't tried stopping services or closing system tray items like Live Mesh. The label does go away if I change the screen resolution and then change it back. Any ideas how I can stop this from happening? It's happened a half dozen times since yesterday and it's becoming quite disrupting to my work. Obviously I added the circle in MS Paint. That part isn't stuck. ;)

• Set up server at home for running svn and Bugzilla

  - by erikric

  Hi, I'm a fairly experienced developer, but when it comes to servers and network related stuff, I'm pretty green. We are developing a web site, and I would like to set up a server that can host my SubVersion repository, and also host Bugzilla for when we release a testversion on some users. So what do i need to accomplish this? I have an old computer that can be used. Can I run this on any OS? It currently has Win 7 installed, but I was thinking about going for Ubuntu instead. Any reason to go for one or the other? I guess I need a web server, and I guess Apache will do fine. Do I need something else to let my computer be available from all over the web, or is a web server and a standard internet connection all it takes? A link some good online tutorials would be much appreciated. And then I mean for real dummies ;). I usually find pages that try to explain setting up servers going way over my head.

• Windows 7 Blank Screen on Boot / Login

  - by Greg

  I have a new system that's having a few problems... sometimes (seems to be when the PC is cold, i.e. has been switched off for a while, though that could be my imagination) I get a blank blue screen when I boot up. The system boots normally and auto-logs-in. The desktop loads and I'm even able to launch applications, but then everything disappears and the screen goes to the default windows desktop blue colour (not the desktop image, just a plain blue with no mouse cursor). At this point the machine completely locks up - I'm unable to even toggle Num Lock and have to hold in the power button for 5 seconds to kill it. Interestingly if I manage to launch some applications before it goes blank, they will usually crash... sometimes explorer.exe will crash too. When I reboot, the system is fine and stable. I've installed the latest graphics drivers and run memtest86+ for 6 passes (and counting) with no errors. The system specs are: CPU: Intel I7 2.66 @ 3.4GHz RAM: 6GB (3 * 2GB DDR3) HDD: 128GB Crucial M225 SSD Motherboard: Gigabyte EX58-UD3R Gfx: ATI Radeon Sapphire 5870 1GB Note: There are a few similar questions but I haven't found one that matches my symptoms

• Home ADSL Modem Dropping Packets?

  - by Cody

  I know this is supposed to be a "pro" forum, but I'm hoping someone can help since my ISP isn't doing much to try and fix things. My ISP has given me a DSL modem / Router combo - a ADB / Pirelli P.DG A2100N and I have a 4096 / 767 kbps connection. I use it purely as modem and router, and have the wireless AP feature turned off. I run it to a Ubiquiti Networks Toughswitch and use a Ubiquiti UAP as the wireless access point - although I've ran tests directly wired to the router with nothing else connected, and still see the same issues. I've been having issues where latency suddenly spikes from 8ms to google.com to 250+ if someone does anything on the internet. If I run a speedtest or something, I can see latencies above 3000ms. Regularly when downloading something, even if the speed is throttled to , it can get random drops to 0kbps every few seconds. Online gaming is impossible because I notice the sudden lag-outs in the connection, and video streams or VoIP drop out as well - it's not at all consistent. I managed to find the password to my modem and I don't think I see anything wrong with the settings - but I looked for the logs and found this: Jun 6 17:10:30 user warn kernel: nf_conntrack: table full, dropping packet.

If that's the case, is there anything in the config that I can change? Or should I buy a new router, a new modem, or both?
