• 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

• 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 (?????????)

• How to configure router to give XBox top priority / most bandwidth?

  - by MrSparky

  Hi all - Newbie here so go easy... and apologies in advance if I blow the community etiquette / rules! Here's what I'm trying to do: I have a "D-Link DIR-655 Extreme N" wireless router and an XBox 360 w/ the old-style wireless connection thing (usb attachment)... I want to configure my router / network to give my XBox as much bandwidth as it wants, whenever it wants. I have tried giving the XBox a unique IP (within my network) and then tweaking the router to treat that IP as a top priority application (using the router's QOS stuff). Problem is whenever I turn off the xbox, I can't connect to the network the next time I start it up. It seems the only reliable setting in the XBox is to use "Automatic" for the IP settings within the Network Configuration area. Supposedly the D-Link ships with default settings that attempt to recognize a game console and give it top priority... but i've not seen good results (lots of stuttering / lag when someone else jumps online, etc). Any suggestions? thanks again!

• Remote assistance from Remote Desktop sessions: unable to control

  - by syneticon-dj

  Since Remote Control (aka Session Shadowing) is gone for good in Server 2012 Remote Desktop Session hosts, I am looking for a replacement to support users in a cross-domain environment. Since Remote Assistance is supposed to work for Remote Desktop Sessions as well, I tried leveraging that for support purposes by enabling unsolicited remote assistance for all Remote Desktop Session Hosts via Group Policy. All seems to be working well except that the "expert" seems to be unable to actually excercise any mouse or keyboard control when the remote assistance session has been initiated from a Remote Desktop session itself. Mouse clicks and keyboard strokes from the "expert" session (Server 2012) seem to simply be ignored even after the assisted user has acknowledged the request for control. I would like to see this working through RD sessions for the support staff due to a number of reasons: not every support agent would have the appropriate client system version to support users on a specific terminal server (e.g. an agent might have a Windows Vista or Windows 7 station and thus be unable to offer assistance to users on Server 2012 RDSHs) a support agent would not necessarily have a station which is a member of the specific destination domain (mainly due to the reason that more than a single domain's users are supported) what am I missing?

• Building a PC for Work and play? [closed]

  - by Derek Organ

  Ok, Its been a long time since I build my own PC so I'm looking to get back into it again and build a new one. First off budget is about €800 excluding the monitor and windows 7 licence and mouse. (just bought a new g500) I plan on using my computer for work, lots of applications open at once but none particularly excessive (photoshop being the most demanding, mostly coding tools) I also use it for some gaming, e.g. COD, Starcraft etc. One thing I do want to do eventually is get a really good monitor with hight resolution and maybe 27" so the graphics card needs to be able to make best use of that. So a few questions 1) Is the bottle neck in performance mostly still the harddrives? 2) Aren't most processors e.g. i5 etc even i3 so far a head of other bottlenecks it makes litte difference the higher you go. Isn't the Graphics card dealing with heavy graphics so what really slows because of a slow CPU? So from this my thinking is to get a SSD drive as my primary drive for OS etc and have loads of memory e.g. 6-8GB and a decent mid level graphics card? It doesn't seem at my level worth spending much on CPU and any other parts really. I basic parts off the top of my head Case, Motherboard CPU SSD Drive SATA Drive Power Supply Memory Cooling (fan?) Graphics Card Network Card Keyboard DVD drive Mouse Windows Monitor Am I missing anything? Any helpful tips or general education much appreciated. Thanks, Derek

• Hardware doesn't work some times

  - by Ali

  I have an Asus n51vf laptop. I bought it not long time ago (less than a month) and installed Windows 7 on it. Since that it wasn't new when I bought it, I don't know, if the problem was occuring before re-installing Windows 7. There are two problems, that might (or might not) have something to do with each other: Problem The less annoying problem is that the screen flickers ONLY on YouTube when scrolling and/or pausing/playing the video or moving the curser over the video. The second more timeconsuming problem is that some of the hardware doesn't work when I turn up the computer. Then I have to reboot the computer and try again. Example: I turn on the computer, and the touchpad doesn't work - I then reboot and it works again. This has so far happened to the screen (leading to a black screen), the keyboard and the touchpad. More frequently the mouse. What have I tried to do so far? I tried reeinstalling the touchpad driver (Synaptic Touchpad driver from Asus Support Page) - didn't help at all. I even tried reinstalling the driver when the non-responding mouse on startup-problem occured (using the keyboard), but it asked me to reboot and didn't help at all. I also installed (and reinstalled) the graphics driver; it's a GeForce GT 130M. Now, the problem never occurs spontaneously - it only appears when booting my computer. I can even use the computer for heavy tasks (games, multiple programs running etc.) with no problem at all. I suspect, that the problem is in some booting mechanism that fails: Maybe the Windows driver loading? Motherboard problems?

• Typical outbound port list for guest access?

  - by Steve

  I manage a weekly rental house that includes wireless Internet access. I've allowed all outbound ports on my router but my ISP has disabled my Internet access twice now because guests have downloaded (or served up) copyrighted content. So I'd like to institute some port filtering to discourage p2p sharing (see disclaimer below). But I don't want to inconvenience the 99.9% of folks who keep things above-board. My question is, what outbound ports are typically open for rental/hotel wireless Internet access, or where can I find such a list? TCP 80,443,25,110 at a minimum. Though my own email service uses 995 and 465 for SSL, some may use IMAP, I personally use SSH and FTP, so I'll open those. Roughly I figure I need to open access to privileged ports, and close 1024 & above. Is there a whitelist I should institute for commonly used high ports? And does it make sense to block UDP 1024 ? Disclaimer: I realize anyone replying to this message could circumvent the port filtering and share content to their heart's content. I do not need comprehensive p2p blocking, which requires more than a port whitelist. Anyone staying at the house shoulders the responsibility for their Internet use, per the rental contract. Also anyone savvy enough to circumvent the port filters would hopefully be savvy enough to use some sort of peer blocking, thereby preventing the ISP from taking down the service.

• open source solution to a gateway for a network of a housing cooperative of 150 people

  - by SirDinosaur

  i just inherited a barely functioning network for a student housing cooperative of about 150 people. in it's current state, as i understand it from the previous person in charge of the network, we have working wireless access points and working ethernet cords going to working gigabit switches going to a barely functioning gateway (right now a simple home router) to one of three possible outbound connections. it is possible to connect to the network through the wireless or ethernet, but especially during peak hours, packets / connections are likely dropped or otherwise get no response. my intuition tells me to replace the gateway with something that can handle multiple outbound connections (WAN) and one inbound connection (LAN), while the rest of the network seems suitable for now. i'm somewhat knowledgable in Linux (been using Debian after first Arch Linux) and i want to use as much open source as possible, but i'm confused whether or not a simple server that i could easily understand will work for this situation. do i need specialized hardware to handle the switching more effectively? if so, what are my options? (i found this, thoughts?) or if a Debian server would work, anything else i should about the specs required for this type of server? also links to any useful information on using open source to maintain this type of network would be most appreciated. <3 P.S. crossposted http://redd.it/yybp2.

• Cable management techniques

  - by cornjuliox

  How do you manage the giant jungle of cables behind your PC? When you have 2 or more PCs next to each other, you wind up with this giant mess cables that's a pain in the neck to clean especially when both computers are running 24/7 and any fidgeting with the cables is likely to cause data loss and/or angry users. So far I've tried masking tape, cable ties and plain old string but none have been very effective. The masking tape kept the cables in place, but over time they ended up leaving this awful sticky residue on the sides of the cables that just won't come off gets all over your fingers and is horrible horrible horrible. I have nightmares about that stuff. We used cable ties and 'folded' up some of the longer cables so that they weren't any longer than they needed to be, but this meant that the position of some of our devices like the keyboard and the mouse were essentially 'fixed' until we removed the ties. The string didn't work much differently and required that we tie them properly or risk it coming loose. I would switch to a wireless keyboard and mouse, but I don't want to have to deal with the added expense of batteries, even the rechargable ones. Plus I don't want them to die on me at a crucial moment (happened to me once while playing Firearms _<). I know that there are people out there with home/office networks a thousand times more convoluted than mine, so

• How to use WPA2 client mode in the Linux-based Cisco WAP4410N access point

  - by joechip

  I have a Cisco WAP4410N access point that I want to use as a client to connect to a WPA2 wireless network (for WLAN service monitoring purposes). Supposedly this access point supports a "Wireless Client/Repeater" mode that allows to do this. The Repeater function is optional (I have that box unchecked so that nobody can connect to this access point wirelessly). I have verified through SSH that the access point gets configured as a client and not as a Master. But it never associates to the SSID I ask it to. This is what iwconfig shows: ath04 IEEE 802.11ng ESSID:"myownssid" Mode:Managed Channel:0 Access Point: Not-Associated Bit Rate:0 kb/s Tx-Power:14 dBm Sensitivity=1/3 Retry:off RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=0/94 Signal level=161/162 Noise level=161/161 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Although I've never done this from the command line, I suppose I could use wpa_supplicant or wpa_client to associate it, but I don't know how to do that without editing configuration files and the filesystem is readonly. Besides, I would have to run those commands manually after every reboot. I'd like to know how to do this the Cisco way, if possible. If not, any trick to make this work would be useful. Edit: This is with the latest firmware, 2.0.4.2. And I found that not all of the filesystem is readonly, since /var and /tmp are mounted with type ramfs.

• Desktop bigger than screen

  - by alex

  I am using MSI U115 11" netbook (OS: Windows XP Home, graphics card: Intel Graphics Media Accelerator 500) and today after I switched it on, desktop was bigger than screen. To be exact: screen resolution was set to the lowest possible and I could move mouse outside of screen (but only below - left, right and up worked normally, mouse could not exceed screen boundaries). I changed resolution back to normal, but the problem with desktop being bigger than screen remained (as before, only lower part - cannot see task bar, etc. When I hit windows button on keyboard, only upper part of menu start is visible). What I already tried was changing all kind of graphics and screen settings - none of them helped. I also tried to restore the system to few days before, but it didn't help neither. What can I do to make the desktop look "normally"? EDIT: Some additional info regarding screen: Sorry it's in polish - but let me explain. There are two screens I can choose (Monitor domyslny means default screen), but the second one (the default one) is not available. After I choose it and click apply number 1. is used (and as you can see it has only two resolutions available. There are more in the second one - but without 1024x600 though). The two ticked and grayed out options here are Use this screen as the main one and Enlarge Windows desktop to match this monitor's size. Too bad I cannot change them. When I choose the second screen, the first box is unchecked and grayed out. The second box is available to be changed but it doesn't matter anyway as after applying changes it reverts to the first screen anyway. EDIT: Intel Graphics Media Control Panel screenshot.

• Dell XPS 17 Laptop USB SS Ports don't work until machine rebooted

  - by Matt

  I have a new Dell XPS 17 laptop and have an issue that the two USB SS ports on the rear of the machine are not recognising anything when I start-up. Have tried mouse, keyboard, headset, USB display. If I plug a USB hub in the power light on the hub lights (presume this is hard-wired) but a mouse plugged into the hub does not light up. If I restart the pc the ports work fine. Also the other two USB ports work fine all the time. I have switched off the power saving setting on the device manager (Power managementAllow the computer to turn off this device to save power) and also in the advanced power settings (USB Settings USB Selective suspend setting:disabled) I have also disabled USB powershare in the BIOS (not sure what this actually does!) This is becoming very annoying having to restart the machine every day before I can start work Running Win 7 Pro x64 EDIT: I have found that setting USB Emulation to Disabled has helped the devices to be recognised during start up but they keep dropping out completely when in use EDIT 2: I contacted Dell about this issue who told me to update the BIOS driver, when I asked if I should downgrade from the factory installed A13 to the A12 posted on the dell website they said no. However there is now an A14 available on the website has anyone tried this?

• Diagnosing a BSOD involving USB

  - by David Ebbo

  [Running Win7 Ultimate 64 bit] My new HP Pavilion Elite HPE-450t has been plagued by BSDO crashes since I got it about 5 weeks ago. The crashes are somewhat rare, sometimes not occurring for 3 or 4 days. I have spent a lot of time trying to isolate the device that could be at fault, but I have seen crashes with only the keyboard and mouse plugged in (as USB devices), and I tried two sets of keyboard/mouse, so I'm running out of ideas. :( The WhoCrashed tool gave this info about my latest BSOD: crash dump file: C:\Windows\Minidump\121310-11887-01.dmp This was probably caused by the following module: usbport.sys (USBPORT+0x2DE4E) Bugcheck code: 0xFE (0x5, 0xFFFFFA8008F571A0, 0x80863B34, 0xFFFFFA80092F2510) Error: BUGCODE_USB_DRIVER file path: C:\Windows\system32\drivers\usbport.sys product: Microsoft® Windows® Operating System company: Microsoft Corporation description: USB 1.1 & 2.0 Port Driver Bug check description: This indicates that an error has occurred in a Universal Serial Bus (USB) driver. The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system which cannot be identified at this time. I looked at http://msdn.microsoft.com/en-us/library/ff560407(VS.85).aspx, and for Parameter1 = 0x5, it says "A hardware failure has occurred due to a bad physical address found in a hardware data structure. This is not due to a driver bug". Should I conclude that it's a hardware issue in the machine itself, rather than a bad USB driver or USB device? Here is the MiniDump, in case someone can get more info out of it: http://ewt52q.blu.livefilestore.com/y1peS4Ce8nSK1SXghzMDoxDWXlaEu-EKCJsv25y8y5DXXIUzZ9U0_tYgFJXd939fykwa0zRmx98IW0PYG18GioqKAuARYjtspSA/121310-11887-01.dmp?download&psid=2

• Xinerama creates a panning viewport

  - by iblue

  EDIT: I've created a bug report: https://bugs.freedesktop.org/show_bug.cgi?id=48458 My Setup I have 4 monitors, 1920x1080, which are in portrait mode (rotated left). They are connected to two radeon graphic cards. As usual, a picture says more than a thousand words. The problem Everything works fine, when Xinerama is disabled. But when I enable Xinerama, things get weird. When I move the mouse of the screen and return, the screen contents begin to move with the mouse, only on this monitor.

• USB Device Not Recognized

  - by Franky Chanyau

  Ok this one gets a little bit complicated but bare with me :D A client brought her computer in to be fixed about a week ago, she says she tried charging a new phone she bought from china and immediately after her usb keyboard and mouse stopped working (typical). I had a quick look at it but because I did not have time, I did a simple system restore and it seemed as if the issue was fixed. I promptly sent it back to her but a few days back she called saying that the issue has returned. Turns out the computer was riddled with some virus that also corrupted her XP install so I had to format the whole thing(yes I tried repairing). I hoped that the format would fix the keyboard and mouse issue but the whole thing has escalated and the computer will throw the "USB Device not recognized" error when I plug anything into the many usb ports it has. I have installed all the drivers (including the chip set drivers) for the pc and even tried the unplugging from the power for a while trick, still no luck. I am sure it is not a hardware issue, but may be wrong. This is way over my head. Can anyone help? Computer: HP Compaq DC7100, Intel Pentium 4, 512mb RAM OS: Windows XP Professional SP2

• Why do messenger keeps coming up when I adjust screen brightness?

  - by Asaf R

  My Dell Studio XPS 13 has a brightness up & down buttons (Fn + up arrow / down arrow), as do most laptops have. It's running Windows 7 64bit and I've installed Windows Live Messenger (build 14 and something) on it. When I hit Fn + down arrow, to reduce screen brightness, the Messenger window pops up. That's true whether it has been running in background (system tray / minimized) before or not. Note, to make messenger hide itself to the system tray, I've set it to Vista Compatibility mode. I don't think that has anything to do with it though, since if I shut compatibility mode off, the problem persists. There's a thread on the matter here, but with no solution. Thanks, Asaf SOLUTION: Stop Intellitype when using internal keyboard. See detailed howto here. EDIT: Some new findings on the matter - If I exit messenger entirely and restart (or simply stop) the service "Windows Live ID Sign-in Assistant" the problem is solved until I run messenger again. It persists even after entirely closing messenger, until I restart the said service. EDIT2: The above service "Windows Live ID Sign-in Assistant" actual name is wlidsvc. There's no shortcut defined for messenger, nor is there any other hot key in its preferences. EDIT3: I'm not sure if it's relates, but some of the Fn keys are not working - Fn + F1 doesn't put the machine to sleep, Fn + F3 doesn't show battery status. EDIT4: Problem probably relates to conflict with IntelliType Pro. See my answer below. Said conflict also causes Undo command when disabling Wireless (Wireless touch button), and other side effects for various keys.

• Is Gmail Being Blocked by my ISP (wait till you read this)?

  - by James

  This is the strangest thing I have ever encountered. I have a desktop on which I cannot access Gmail and also youtube sign in (I believe since youtube is owned by google they both use the same sign in system). So okay, maybe my ISP is blocking these for some reason or maybe my firewall is, or maybe there is something wrong with my connectivity, right? NO. On other computers that uses the same connection via a wireless router I can access both gmail and youtube sign in just fine. On this computer which doesn't have a wireless card and so I have to connect via Ethernet cable (connected to a USB converter since the Ethernet port doesn't work anymore) I can access all sites and services including things like aol and hotmail. But only when it comes to gmail, do I get complete and utter throttling. I even turned off my AV ad Firewall momentarily and no luck. The gmail ages starts to load and by mid point it just stays there loading and loading and loading... never ends. I tried everything, I reset the modem and router multiple times. I reinstalled my operating system from a vista to a windows 7 hoping a complete reinstall would solve the issue, but no luck. So can anyone for the life of them figure out why this could be? And yes, I am going to call my ISP but not to solve this issue, but to cancel them. I want to upgrade to cabel from DSL anyway. I didn't mention my ISP because I'm not sure if that is within the rules (if it's okay some one let me know and I will). P.S. All this happened one day, before gmail was perfectly accessible in this computer. I can't remember anything special that happened on that day prior to this. The only thing I can think of is, my ISP or Google itself is blocking this computer based on it's mac address, but I don't know if that's even done. Additional info: PC: Windows 7 Ultimate 32 bit Connection Type: DSL Connecting Medium: Ethernet cable via USB converter

• XP Pro freezes on welcome screen

  - by Peter B

  I have a problem that sounds much the same as http://superuser.com/questions/83101/how-to-diagnose-a-freeze-on-startup-in-windows-xp About every 2nd or 3rd boot, XP-Pro freezes on the Welcome page (the one showing the user name icons). The mouse moves the cursor OK, but clicking on an icon does nothing, and neither does any keystroke. If you press too many keys there is a beep and after that the mouse won't move the cursor anymore. The work-around is always to reboot into Safe mode and request a CHKDSK /R After this, the next boot is fine. There are no related entries in the Event log when the problem occurs. The only two entries are: "Microsoft (R) Windows (R) 5.01. 2600 Service Pack 3 Multiprocessor Free." "The Event log service was started." Update 1: Many thanks for that but I found no problems with any diagnostics I have run. But, I have managed to locate, and code round, the source of the problem - which is with whatever processing goes on behind the XP Welcome (as opposed to "classic") login screen. Unfortunately, having classic login means you don't get the useful Fast User Switching (FUS) login/switch mode. So, to retain this, my fix is: Add a Windows shutdown script (using gpedit.msc) to force "classic" mode for the first logon after next XP startup, by running: reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v LogonType /t REG_DWORD /d 0 /f Add a Scheduled Task to run at User Logon that enables Welcome screen (and hence FUS) by running the same command with 1 instead of 0 after the /d flag. The task is run as a privileged user (who can run "reg add").

• Port forwarding + shared connection with Ubuntu

  - by Joey Adams

  Because my wireless router's ethernet ports are defective, I set up a shared wireless connection from my laptop (which has wifi) to my eMac (which does not) via a crossover ethernet cable. The laptop is behind a router as 192.168.1.131, and the eMac is behind the laptop as 10.42.43.1 . The laptop is running Ubuntu 9.10 (Karmic). I achieved the shared connection through NetworkManager Applet. I right-clicked on the network icon at the topright, went to Edit Connections, selected the Wired connection named "Auto eth0", clicked "Edit...", went to the "IPv4 Settings" tab, and selected the Method "Shared to other computers". The eMac can now access the Internet. Now I want to enable port forwarding. There's a game I want to play that needs port 6112 forwarded (both TCP and UDP) in order to host games. I set up the router to enable port forwarding for 192.168.1.131 (the laptop), but port forwarding still isn't available on the eMac. I suppose I need to pretend my laptop is a router and configure port forwarding on it, indicating that incoming connections to the laptop (192.168.1.131) should be forwarded to the eMac on the shared connection (10.42.43.1 ). Thus, packets coming into the router on port 6112 would be redirected to the laptop (by the router), then to the eMac (by the laptop). My question is, how would I do that on Ubuntu (in light of NetworkManager's presence)? Also, if I can't get this to work, does anyone mind hosting a comp stomp? :D

• Using a Level 2 switch as a core switch

  - by imtech

  I have a small user base of about 20 people on at a time and spiking up to about 80 people during peak times. Most people (80+%) are connected over our Aruba managed wireless system. We have a Windows Domain. We have 3 24-Port switches all connecting back to a central 48-port switch where additional access ports, firewall, servers, and wireless controller all centrally connect back to. It's a flat network with dumb switches. I'm in the process of upgrading our infrastructure. Cisco pricing for switches is pretty high for us so I've been looking at HP Procurves which seem to be within our budget range. I want to eventually make use of 802.1x, SNMP, QoS for possible VOIP upgrades, VLAN to separate guest VLAN from authenticated users, and other more advanced features. PoE would be nice but that's probably too expensive for us. I was thinking of having our core switch be a Procurve 2610 and the rest of our switches that centrally connect to it be Procurve 2510s. A true and full blown level 3 switch is way out of our price range but a 2610 seems to be good enough for us. The 2610 does static routing which ought to be good enough for us but I'm in unfamiliar territory so I'm looking for any gotchas. Also, should all the switches be 2610s or just the core switch? Do I even need the 2610, can I just go with all 2510s? I'm new to VLANs as well so I'm not sure what it is I need but I would like an affordable infrastructure that won't need replacing 2-3 years down the line because I choose a product that was lacking.

• Thundrbird 3: can't change column width?

  - by rumtscho

  I recently installed Thunderbird 3.0.3. Just noticed a suboptimal UI setting: in the upper pane, which lists the e-mails in the current folder, the Date column is about 200px wide. So when I keep the window at 480x600, all I see in a row is: | tree icon | favourites icon | attachment icon | read icon | junk icon | Date and time, followed by 5cm whitespace | ... | P Where "P" is the first letter of the name of the sender. And the "..." is actually shown this way, I have no idea which column it is meant to be. But I don't see neither the sender, nor the message subject, which makes scrolling a folder for a certain mail rather pointless. I see these when I maximize the window, actually the columns are then not only bigger, they are arranged in another sequence. But I feel that holding a mail client permanently maximised at 1600x1200 is a waste of screen real estate. My naive solution attempt was to try to go with the mouse cursor to the right edge of the date column and try to shrink it by moving the cursor left while holding down the left mouse button. Not only is this default behaviour for all resizable columns I've ever encountered in GUIs, the cursor actually turns into a horizontal double-headed arrow. But pulling has no effect at all. I cannot make a wide column narrow, and I cannot make the narrow columns wide. I didn't find anything in the preferences either. So can please somebody explain how to get the columns arranged sensibly?

• Coming from Win XP to 7 and having new accessibility software problems

  - by Anonymous Jones

  I just switched from Windows XP Pro SP3 (32bit) to Windows 7 Ultimate (32bit) on a new PC. Now, both the new onscreen keyboard and a utility for sending mouse clicks are being problematic. The problem with 7's OSK is that some things I type only work intermittently or just dodgily. Like Alt+Tab with multiple Tabs, other Alt/Ctrl/Shift/Win key combinations, and the context menu key. Sometimes apps will not take focus for input at all. I use the OSK it in 'hover' mode, on 0,5 seconds. The clicking tool is Point-N-Click, which sends clicks when I dwell anywhere for 1.25 seconds with the mouse pointer. http://www.polital.com/pnc/ The problem with it is that sometimes it fails to click. Most often this happens in some of the control panel sections, on the taskbar, and when UAC pops up. It seems to occur in conjunction with OSK usage a bit too, I think. I'm using an Administrator account. DEP and UAC settings are default. What can I do to fix or work around either of these problems? I'm disabled so this really is killing usability.

• What is causing sudden freezing during running real-time program?

  - by Trevor Boyd Smith

  So I run a high intensive (CPU/GPU) real-time program. During normal execution suddenly everything freezes for 1-4 seconds. I opened "Process Explorer" in the background to help gain insight and maybe identify something. Here is what the CPU/GPU graphs looks like when I align them in time: Notice the 4 distinct drops in both the CPU/GPU. You can see that it goes from some sort of positive CPU/GPU usage to almost zero. These drops in the graph align with when the real-time program suddenly freezes. How do I find what is causing these sudden drops? NOTE: When you put your mouse over the graph it tells you the time, accurate to the second, for where your cursor is. Maybe this mouse over feature could be helpful in some way (e.g. what if you had a log of all processes every 100ms). EDIT: The real-time program is a video game and so I can't watch some sort of instrumentation while the video game is running. I need a solution that let's you look back in time somehow to see what was happening when the slow down occurred. EDIT: RE - Recording Data vs using real-time monitor: So the windows performance recorder is for some reason not recording what I expect it to record. So I switched to using "perfmon" and then opening it's "resource monitor". RE - Setting it up so I can view real-time monitor: In the video game I set it to spectate and then put the video game in "windowed" mode so that I can view the real time display that Resource Monitor has. Now that I can get semi-real time (only once per second... how do you get more than once per second?) I started looking at the various real time data readouts. Getting to the cause: I noticed a strong correlation in high disk IO and low CPU usage (which is also seen by having in-game freezing). How do you use resource monitor to find out who is doing all this offending disk IO?

• Stop the constant random reboots of my GIGABYTE GA-B75M-D3V

  - by Frederic

  I've got some issues with a new system. It's rebooting constantly. The system consists of a: brand new: Gigabyte GA-B75M-D3V with F9 BIOS (latest) Intel Core i5-3470 Ivy Bridge 2x 8GB G.SKILL Ripjaws 1600MHz memory (mem-tested x-86) coming from a stable system: Creative Soundcard X-FI Titanium Asus Radeon HD4850 OCZ Vertex 3 120G SSD Sata 3 Hard disk 1TB Sata 2 ASUS Blu-ray Drive PSU 400w Connected peripherals : Toshiba tv (displayport on dvi of MB or HD4850) Wired mouse, wireless keyboard (logitech) Bluetooth usb key Azio main problem : it's not possible to read the errors from the MB. nothing on the manual neither on internet. At the beginning, I received a MB with graphic problems and the problem of rebooting. I RMA'd it. The new one doesn't have any graphic problems. but it's still constantly rebooting. I removed everything except the HD, the sound-card, the blu-ray drive and the wireless keyboard. It's still unexpectdly rebooting. I'm running a test with just the motherboard and the HD. I will update this text after the test. I've got some questions : Somebody have an idea of a test? The PSU could cause that problem? I used it a lot of years with the stable system. Update 1: BTW, if anyone has the same problem, the manual won't say it but you'll need to reset the bios between two tests (the screwdriver on the two pins) if you suspect a problem of compatibility .
