• Dell 620 display is too bright to use

  - by keith

  I have a Dell D620 with a display problem. In windows 7 the display seems to be too bright, the text is broken up, the only way to see the mouse is at a very oblique angle. Changing the brightness with fn and brightness control has little/no effect. When I put it in high contrast mode I can see all the colors, but any windows pictures etc are still useless. I cannot get it to connect to an external monitor via VGA port or via a USB-VGA connector.

• dell vostro 1310 with nVidia 8400M display problem

  - by Arthur

  Hi everyone, i hope someone can help me with this problem. I have a Dell vostro 1310 Laptop with 32 bit vista and a 8400M nVidia chip. Recently i have noticed performance issues when my girlfriend was playing Sims 3, and then one day i turned it on and all i got was a thick white line at the bottom of the screen. i heard the OS start up so automatically i thought it was a damaged screen, but i had doubts so i plugged it into an external display via the vga port. it worked but everything appart worm the OS choice menu looks distorted beyond belief. even the bios screen had multicoloured lines running down the screen. The resolution is non existant, the screen only shows a 256 colour pallette and is heavily distorted. i barely managed to get to the device manager where i found the gfx card with an exclamation mark. does anybody have suggestions? should i buy a new mobo or are repairs possible? thanks in advance

• Ubuntu VPN Server (PPTPD) Configuration - Pass Traffic to Internet

  - by SnAzBaZ

  I am trying to configure PPTPD on my Ubuntu box to pass all VPN traffic through to it's internet connection, so I essentially want it to work like a Proxy. I think the problem is that no default gateway is being assigned to my PPTP client (Windows 7). I can connect to the VPN fine, I get an IP address and DNS servers but no default gateway. Do I need to configure a specific option to tell the VPN server to forward all traffic it receives down it's eth0 port and out to the internet. Thanks!

• Configuring vsftpd with nginx on ubuntu

  - by arby

  I have vsftpd installed on Ubuntu 12.04LTS along with nginx, php, and sql on an Amazon ec2 instance. The web server is good to go, but I'm having trouble connecting to the FTP server. I'm not quite sure how to set the privileges or what configuration options I might be missing. By default, the location of the web root is at /usr/share/nginx/www and it is owned by root:root. The web server runs as user www-data in the group www-data. I've opened port 21 and set the passive ports in the ec2 backend and ufw firewall. In vsftpd.conf, I have: ... anonymous_enable=NO local_enable=YES local_umask=0027 chroot_local_user=YES pasv_enable=YES pas_max_port=12100 pasv_min_port=12000 port_enable=YES ... Now, I'm unsure how to create the FTP user that when I login, displays my web directory with write access. I've tried it a few different ways, but I keep running into errors (either no connection, no write access, or very slow timeouts.)

• How to Enable Ports 25 - 28 on a Cisco Catalyst 3750

  - by Jared Brown

  I am trying to enable ports 25 - 28 on my 28 port Catalyst 3750. These four ports are my fiber ports. I am using the following command to bring up that interface. interface range Gi1/0/25 - 28 That works and it dumps me in the config-if-interface prompt. This is where I get stuck. I just want to enable these four ports and have them be in VLAN1 and On just like ports 1 - 24. How do I do this?

• Can Remote Desktop be set up to use IPv6?

  - by Garrett

  I have both a Windows 7 Ultimate and a Windows XP Professional machine set up on my home network. I would like to be able to access them from school. Port forwarding is not currently an option (long story). Is there a way to set it so that I can RDP (yes it has to be RDP not something like TeamViewer or LogMeIn) over IPv6, possibly using Teredo? I have tried but I can't seem to get it working. Also I cannot ping these machines' IPv6 addresses. How can I get this set up?

• Apache configuration to accept all data

  - by ServerDown

  Hi, I have apache running on port 7979 to talk with a device that sends data to webserver and later will run php scripts to process and send reply xml. The problem now is that it sends data like POST HTTP/1.1 Content-Type:text/xml Content-Length:369 Followed by XML When apache sees this it gives a 400 error. Since the device cannot be changed is there any way to accept the full data sent from the device and write to some log? Currently apache simply keeps sending 400 errors back. If there was a way to log the entire xml or create some custom handler for 400 error then the xml could be read by a php script. Looking forward to solutions.

• GDM login screen is not displayed with VNC

  - by niboshi

  Hi, I set up VNC server with xinetd. Also configured GDM so that XDMCP is enabled. VNC connection seems okay, but GDM login screen is not shown. Instead I can only see old bare X screen (gray meshed background and X-shaped mouse pointer), which I can't do any interaction with it. What can I do to fix the problem? No log is written below /var/log/. Server distribution: Ubuntu marverick /etc/xinetd.d/vnc is like below: service vnc1024 { disable = no socket_type = stream protocol = tcp wait = no user = nobody server = /usr/bin/Xvnc server_args = -inetd -query localhost -geometry 1024x768 -depth 24 -once securitytypes=none port = 12345 } /etc/gdm/custom.conf: [daemon] [security] DisallowTCP=false [xdmcp] Enable=true [gui] [greeter] [chooser] [debug] [servers] /etc/services is also configured. Thanks

• Setting Redmine path

  - by David Parunakian

  Hello, How can I set the path on which Redmine should be run, e.g. example.com:3000/redmine instead of example.com:3000? There is an appropriately named option in the settings panel, but it serves a different purpose, according to the documentation and experimental observations (it is used to write URL in emails sent to users). A wider picture: I need this in order to properly serve Redmine on port 80 over Apache's mod_proxy (i.e. at example.com/redmine). The problem is that when running it on /, the home page fails to load the necessary resources (such as JavaScript and CSS files). Any workarounds?

• How to Use 3 Monitors

  - by The.Anti.9

  Right now my setup has a nice big 24" flatscreen in the center, and a 19" flatscreen to the left. And a big gaping hole on the right. I have a 3rd monitor to put there, but I'm not sure how to get the computer to recognize it. Do I need a graphics card with 3 ports? Or can I span the monitors over non SLI-Linked graphics cards? Is it possible to plug my 3rd monitor into the on-board VGA port and have it work?

• Format External HD on Airport Extreme Base Station?

  - by David.Chu.ca

  I just got an Airport Extreme Base Station. I am planning to use this one replace my current Linksys router. This works fine. My another purpose of getting this device is to use its USB port to connect to several external HDs as my backup Time Machine. I can see one 500GB HD through Airport Base Station. However, I cannot format it by using Disk Utility. What I did is to connect the HD to my iMac directly first and then clean and format the disk by Disk Utility application. Then I move the HD to the Airport Base Station. After that I can designate the HD as my Time Machine destination. Is there any way to format the HD connected to Airport Base Station? Any issues to use an external HD through Airport Base Station for Time Machine backups?

• Lightweight monitoring for a Windows XP laptop

  - by kazanaki

  Hello I have a windows XP laptop in a remote location. I would like to have an overview for CPU/Memory statistics from a remote location. Monitoring a specific service (a Tomcat instance) would be nice but not essential. I have seen the monitoring solutions (Nagios, cacti e.t.c) and they are all very heavy. I do not want to install mysql, web server and other stuff like that on the laptop. I don't even need a web solution at all. It could just be a simple command line app with a server port and on my machine another GUI application would connect there (and not a web browser) Is there something like this available?

• How long do managed gigabit ethernet switches take to boot up?

  - by Warren P

  One critical drawback that I have found in researching managed-switches, and one that I have some past experience with is that anything with "lots" of firmware is going to have lots of issues associated with that firmware. We are in the middle of researching rackmount gigabit switches (48 port). It looks like for 48 ports, our only choice is managed switches (Dell, Cisco/Linksys,HP, etc). What I want to know, that I can not find out much about is the boot-time for various managed switches. If you own one, can you please answer with the model number, and the cold boot time in seconds. I have read online that Linksys (now Cisco) SRW series sometimes take almost 5 minutes before they are fully booted up, and that is an unacceptable cost for us. I particularly want to know about Dell PowerConnect managed switch bootup time (model 3548 and 5448), and would like to confirm the 5-minute boot time on the SRW2048 or similar model, and any HP ProCurve boot up times. The composite of all those figures ought to form an interesting overall performance picture.

• hung up troubleshooting packet discards

  - by Chris Satola

  I realize my question is generic, but hopefully someone may have some guidance for me. My network consists of Cisco switches. I am seeing a significant amount (upwards of millions of packets per day) transmit drops between two switches. One being a 3750 and the other a 3560. The peak throughput of this link is only upper 400Mbps, so it shouldn't be a bandwidth issue. At this point, I am sort of clueless where to look or what tools I can use to determine what packets are dropping and why. I can setup a SPAN port on that link and wireshark it, but I don't know if that could tell me anything. Does anyone have any suggestions? Thanks in advance.

• Can't find generic USB audio driver for a Samson COU1 USB microphone

  - by marcipollo

  I am unable to use a Samson USB CO1U microphone on a PC running XP, SP3. When I plug it into the USB port, Windows generates the sound indicating that it has found new hardware, and the green LED on the mic lights. But, it does not work, and the device manager reports that it cannot find a driver after searching. The same mic works on a Vista machine. Samson has no driver on their Web site, and insists that the generic audio driver in Windows should work. (http://www.samsontech.com/PRODUCTS/productpage.cfm?prodID=1810). I cannot find a generic USB audio driver at Microsoft.com. Can anyone help? Larry

• What settings need to be changed to allow EC2 instances to use Amazon's Route 53 for DNS?

  - by ks78

  I have a number of Amazon EC2 instances, all running Ubuntu, which I'd like to configure to use Amazon's Route 53. I setup a script, following Shlomo Swidler's article, but ran into script-related issues, which were answered here. Now, I have the script working, but my instances are still not able to access Route 53's DNS. By this I mean, they are not able to resolve hostnames to IP addresses. My instances are currently configured with the DNS server IP address Amazon pushes out to them by default, does that need to be changed when using Route 53? I'm also IP-restricting my instances using the Security Groups. Could that be the problem? Is there a certain IP address or port I should open to allow communication with Route 53? It seems that DNS requests should be originating from my instances so the Security Groups shouldn't be an issue, but I've been wrong before. If anyone has any ideas, I'd really appreciate it.

• How do I set up my own proxy server?

  - by NJTechGuy

  This website (abc.com) slowed access from our original IP address. How do I implement my own proxy server to hide my IP while browsing abc.com? Do I need special hardware/software combo to achieve this? If I can generate about 5 proxies and alternate amongst those 5 while browsing abc.com would be awesome. Please suggest. Thanks guys! p.s : I want to know if I can generate proxy IPs of the type 123.34.21.140 prot 80 on my own? I want to use those IP/port combos in my Python scripts (urllib2/set_proxy).

• netcat as a multithread server

  - by etuardu

  Hello, I use netcat to run a simple server like this: while true; do nc -l -p 2468 -e ./my_exe; done This way, anyone is able to connect to my host on port 2468 and talk with "my_exe". Unfortunately, if someone else wants to connect during an open session, it would get a "Connection refused" error, because netcat is no longer in listening until the next "while" loop. Is there a way to make netcat behave like a multithread server, i.e. always in listening for incoming connections? If not, are there some workarounds for this? Thank you all!

• PBX with Fax and Google Voice

  - by Phill Pafford

  Looking to replace/port my home number which I use for mainly faxing for my home business to a PBX server ( Thinking Asterisk or Elastix ). My question is: Does Asterisk/Elastix support Faxing ( Incoming / Outgoing ) Does Asterisk/Elastix support Google Voice Here is what I'm looking to do: Run some sort of PBX software from my own home server that will allow me to use Google Voice for my home number, possibly allow multiple Google voice ( Though I could live with just the one ) and must support Faxing ( Incoming and Outgoing ). Would Asterisk/Elastix support all of this or would you recommend something else for this? Looking to avoid some of the pitfalls that could happen I like Ubuntu if a Linux environment is needed

• Netgear WNR1000 WiFi speed

  - by Kamil Klimek

  I have Netgear WNR1000 150N, Macbook Pro 13" with Broadcom BCM43xx 1.0, Network connection 60mbps When I connect through the cable I easily get around 60mbps. When I go through the WiFi it's capable to get only 32mbps at tops. Any ideas why is that? Is that my router limitation or maybe my WiFi card? If it is routers fault what router would you suggest. Best router would be with usb port for external hard drive. Forgot to add screenshot with connection details: Szybkosc transmisji == Transmission speed

• Juniper J4350 out of order

  - by Benjamin Baron

  I have got two (2) Juniper routers J4350 that are out of order : All the interfaces are down (leds on the interfaces don't ligthen, ping dosen't respond) No output on the console port (even when booting) I've tried to reset the router (holding the RESET CONFIG button on the front panel during 15 seconds) and nothing happened, even while booting the device I've opened the router to check the fans. I've removed some dust and nothing has changed. I wanted to precise that the leds on the front panel are all on: The POWER led is green The STATUS led is red The ALARM led is on and is orange The HA (High Availablity) is on and orange as well I have found nothing on the Internet to solve this problem... Thank you for helping me :)

• Is an Ethernet point to point connection without a switch real time capable?

  - by funksoulbrother

  In automation and control, it is commonly stated that ethernet can't be used as a bus because it is not real time capable due to packet collisions. If important control packets collide, they often can't keep the hard real time conditions needed for control. But what if I have a single point to point connection with Ethernet, no switch in between? To be more precise, I have an FPGA board with a giga-Ethernet port that is connected directly to my control PC. I think the benefits of giga Ethernet over CAN or USB for a p2p connection are huge, especially for high sampling rates and lots of data generation on the FPGA board. Am I correct that with a point to point connection there can't be any packet collisions and therefore a real time environment is given even with ethernet? Thanks in advance! ~fsb
