  • How to set up wireless access on a Cisco router

    - by Carlos
    Hi, I've set up my 877W according to the configuration listed in this forum post: IPTV over Cisco 877 (It's the working configuration at the bottom of the post) Note that I have an 877W, so it also has a wireless radio. Now, I've gotten the whole setup to work, so IPTV is working, and I can access the internet via the ethernet ports. Now I'm trying to figure out how to allow access via the dot11radio interface. I've gathered that I basically need to create a bridge group, and bridge the radio to the internet VLAN. However, when I add a bridge-group 2 command to VLAN1, it seems to take down the whole internet VLAN. (The IPTV continues to work.) This makes the router itself inaccessible (I've got a laptop, so no serial) and I end up having to reboot the router. Can anyone tell me how to a) Allow wireless access to the internet (preferably with WEP, to match my old router) b) Determine what makes the router inaccessible when I add the new bridge group c) Forward the IPTV traffic onto a machine on my internet VLAN

  • Mouse and touchpad move at different speeds

    - by Juan Manuel
    I have a compaq 610 running windows 7, and I use a USB mouse on it. The pointer speed is different for the mouse and the touchpad, so when I go to a meeting and take the notebook but not the mouse, the pointer moves too slow using the touchpad and I have to manually adjust it (of course when I return, I have to slow it down because the mouse would move the pointer too fast). Is there any way to fix this, or to have this setting separate for both devices?

  • Massive amount of subfolders and long subfolders. ¿How can I delete all of them?

    - by Carlos
    Good day. We have a little problem here. We have a share with the backup of all the server's offices, Its a really big share with more than 8.000.000 files. Our users usually give long names to the folders they create, and then make subfolders (long too) and more subfolders... and more suboflders.... We have a new share with more capacity, and with a simpe robocopy bat we copied all the files and folders (some give problems, but we manually copied them) But the problem is deleting them. del command didnt work well when so long paths, neirder rmdir... I'm tried some commanders, but no luck. Can u recommend me any tool that can delete recursively or able to delete 255+ paths? Edited: The SO on background of the share it's NetApp OS. But I can access it from Windows Servers. 2000 and 2003 Thanks.

  • Computer wakes itself few seconds after hibernation

    - by Juan Zamudio
    Hi all, this is the situation, this is a Dell Optiplex 755, I recently upgraded it to Windows 7 64 bits, it had Windows XP SP3 previously, on XP I never had a problem hibernating the PC, now with Windows 7 64 every time I hibernate the PC it wakes it self after 5 or so seconds. Here are the steps I already tried: On Windows 7 I enabled the hibernation following this steps In the MoBo the sleep settings are on S3 In the Mobo I disable remote wake ups I have disabled the remote wake up in the NIC When I run the lastwake command I get unknown device or something like that I already disable the wake timers on Windows I have the latest drivers from Intel, but I just found out that in the device Manager I get a warning sign on the "Intel AMT SOL (COM3)" device saying that it failed and windows stopped the device, I reinstalled the Intel drivers but nothing changed. The only thing that I haven't touch is Intel ME in the MoBo but I don't if that could help and what settings are correct. Thanks for you help.

  • Wireless router setup for 1-1 NAT

    - by Carlos
    What I have: A linksys router WAG160N with firmware version 2 A "pool" of 5 external static IP's provided by my ISP 213.xx.xxx.n All the required configuration values for the static IPs such as (Subnet Mask, Gateway and static DNS 1, 2, 3) Current WAN Configuration: Encapsulation: RFC 2364 PPPoA Multiplexing: VC QoS type: UBR DSL modulation: MultiMode What's connected to the network: 1 x Server (That I want to make available to the outside) 5 x Desktops with static internal IP's, such as 192.168.0.xx 2 x Network printers, also with internal static IP's 2 x Laptops 1 x NAS (Network Attached Storage) also on static IP What I want to do: I would like to make the server available from outside the network, for example from your house. The problem is that Im not really sure how to do this. I have tried following the steps on the instruction manual in Linksys but they do not seem to work, once I set it up as shown bellow, I loose internet and all hell breaks loose. Going into further detail, I would prefer if the network is changed as little as possible, by this I mean that all the computers stay networked within eachother and only the server is accessible from the outside the network. What I need HELP with: I have read around that it is possible to set a 1-1 NAT (I know where it is in the menu but have no clue what it does...) so that I can NAT a single public IP directly to a single private IP (in our case the server). But please, How do I do that? Or maybe an alternative?

  • A design for watching IPTV anywhere in the house?

    - by Carlos
    I'm currently getting TV and internet via IP to my house. The service comes into an ISP-supplied Router (ST585) which is in turn connected to an IPTV box. I need to replace the router, as it's port forwarding seems to be broken, so I was thinking of getting a box with an IGMP proxy. I once mistakenly got a non-IGMP box, with the result that the internet worked, but the IPTV didn't. The trouble is, I have no idea how to set up the IPTV part of the installation. I do have a copy of the ST585 configuration, but it doesn't look anything like the Cisco stuff that I learned about at CCNA. What are the steps necessary to reproduce the IGMP setup? I was thinking of WireSharking the communications on the network, but I suppose I'd need a hub for that? As a bonus, since the packets are coming in with the TV signal, is it possible to mess with the IGMP setup so I can watch TV anywhere in the house?

  • Problem remotely managing Exchange Server 2010

    - by Carlos
    I can't connect to the instance of exchange server 2010 through EMC on the local machine running w2k8 r2. I've checked all the default website bindings, the kerberos auth and WSMan are set to native type in powershell and I still get this error message. Connecting to remote server failed with the following error message: The WS-Management service does not support the request. It was running the command 'Discover-ExchangeServer -UseWIA $true -suppresserror $true'

  • windows printer spool gets stuck with file at 64kb from linux and mac

    - by Juan Diego
    Hi I have two printers one on a file server with windows 2003, and other with windows XP. The thing is that when i try to print from my machine, my file stays in queue for ever, it says 64kb out of whatever the file i send. I have seen similar problems with some machines that run on Mac OS X. The windows machines apparently have no problems printing. They are not connect through active directory, just the network. In the past I have seen people install non microsoft windows Printer server on windows, i dont remember the name of any of the programs. I have being googling a lot and have not found anything to replace the microsoft print spooler service, maybe i am mistaken. Everyday I have to restart the print spooler service i even created a bat file for it. I am out of ideas here.

  • SQL server availability issue: large query stops other connections from connecting

    - by Carlos
    I've got a high-spec (multicore, RAID) server running MS SQL 2008, with several databases on it. I have a low throughput process that periodically needs a small amount of information from one of the DBs, and the code seems to work fine. However, sometimes when one of my colleagues does a huge query against one of the other DBs, I see full CPU usage on the machine, and connections from my app time out. Why does this happen? I would have thought the many cores and harddisks would somehow (together with cleverly written DB server) be able to keep at least some of the resources free for other apps? I'm pretty sure he doesn't use multiple connections for his query. What can I do to prevent this?

  • TCP Keepalive and firewall killing idle sessions

    - by Carlos A. Ibarra
    In a customer site, the network team added a firewall between the client and the server. This is causing idle connections to get disconnected after about 40 minutes of idle time. The network people say that the firewall doesn't have any idle connection timeout, but the fact is that the idle connections get broken. In order to get around this, we first configured the server (a Linux machine) with TCP keepalives turned on with tcp_keepalive_time=300, tcp_keepalive_intvl=300, and tcp_keepalive_probes=30000. This works, and the connections stay viable for days or more. However, we would also like the server to detect dead clients and kill the connection, so we changed the settings to time=300,intvl=180,probes=10, thinking that if the client was indeed alive, the server would probe every 300s (5 minutes) and the client would respond with an ACK and that would keep the firewall from seeing this as an idle connection and killing it. If the client was dead, after 10 probes, the server would abort the connection. To our surprise, the idle but alive connections get killed after about 40 minutes as before. Wireshark running on the client side shows no keepalives at all between the server and client, even when keepalives are enabled on the server. What could be happening here? If the keepalive settings on the server are time=300,intvl=180,probes=10, I would expect that if the client is alive but idle, the server would send keepalive probes every 300 seconds and leave the connection alone, and if the client is dead, it would send one after 300 seconds, then 9 more probes every 180 seconds before killing the connection. Am I right? One possibility is that the firewall is somehow intercepting the keepalive probes from the server and failing to pass them on to the client, and the fact that it got a probe makes it think that the connection is active. Is this common behavior for a firewall? We don't know what kind of firewall is involved. The server is a Teradata node and the connection is from a Teradata client utility to the database server, port 1025 on the server side, but we have seen the same problem with an SSH connection so we think it affects all TCP connections.

  • Library conflict in Mac OS X

    - by Juan Medín
    I was trying to install the ImageMagick library on Mac OS X Snow Leopard, and first I tried port and, after it failed, homebrew. It updated some dependencies and installed ImageMagick without problems. So far so good. The problem came when I ran Apache. I got the following error in the system log: 07/04/11 12:55:15 org.apache.httpd[41841] httpd: Syntax error on line 115 of /private/etc/apache2/httpd.conf: Cannot load /opt/local/apache2/modules/libphp5.so into server: dlopen(/opt/local/apache2/modules/libphp5.so, 10): Library not loaded: /opt/local/lib/libpng12.0.dylib\n Referenced from: /opt/local/apache2/modules/libphp5.so\n Reason: image not found I checked the /opt/local/lib and surprise! I don't have the libpng12.0 but the libpng14.0. So, as far as I can tell, something went wrong installing the ImageMagick library. Now, I can't find a way to rollback to the previous libraries, other than copying them from the backup. Do you know if is there a way to recover the previous state or reinstall Apache? Or is this just a corrupt state and I must reinstall OS X?

  • Cannot read/write a second drive in MBP 13

    - by Carlos
    I changed my original HDD for a SDD earlier this year and I just got one more SSD for my MBP 13 (2012) that I used to replace DVD drive. I'm using Mountain Lion. The SSD looks to be recognized allright, but I can't format it. Then I removed the main drive and tried the new one as the main drive and did the boot using a USB drive with MAC OS and everyhing worked as it should (like I just had one drive). However when I bring the first drive back together with the second they both show up but I can't use it. Seems like I have no permission, but when I look at it's properties it says I can read and write to it. Any ideas? Thanks a lot!

  • running a web server with encrypted file system (all or part of it)

    - by Carlos
    Hi, I need a webserver (lamp) running inside a virtual machine (#1) running as a service (#2) in headless mode (#3) with part or the whole filesystem encrypted (#4). The virtual machine will be started with no user intervention and provide access to a web application for users in the host machine. Points #1,#2 and #3 are checked and proved to be working fine with Sun VirtualBox, so my question is for #4: Can I encrypt the all filesystem and still access the webserver (using a browser) or will grub ask me for a password? If encrypting the all filesystem is not an option, can I encrypt only /home and /var/www ? will apache/php be able to use files in /home or /var/www without asking for a password or mounting these partitions manually? Thanks

  • How do you find all dependencies of a database table?

    - by Carlos
    In MS SQL 2005, is it possible to find out which tables/columns are being used either as keys in another table, or as part of a stored procedure? The reason is I'm trying to clean up some old stored procs and tables, some of which can be removed, some of which can have columns pruned. But obviously I don't want to remove stuff which is being used.

  • Getting "is not a valid mailbox" when email sent to primary address

    - by Juan Tarquino
    Anyone outside my domain who sends me an email is getting a bounced email with the following error from Exchange: 550 550 5.1.1 [email protected] is not a valid mailbox (state 14). I can't receive emails from external addresses until I send an email to one of my secondary addresses. Once I sent it to my secondary address, my primary address will start working for a while and fail again after a few hours. We use Exchange 2003. Anyone has any suggestions on what to try?

  • VS2010 on multiple monitors

    - by Carlos
    I'm using VS2010, which has the cool feature of allowing you to drag panels out of the main IDE window. I like to drag some of the panels off to one of my other monitors. Unfortunately, after each run/debug session, VS2010 seems to forget where I had the panels, and dumps them right in the middle of the IDE window, and I have to move it again. Does anyone know what to do about this?

  • Resource consumption of FreeBSD's jails

    - by Juan Francisco Cantero Hurtado
    Just for curiosity. An example machine: an dedicated amd64 server with the last stable version of FreeBSD and UFS for the partitions. How much resources consume FreeBSD for each empty jail? I mean, I don't want know what is the resource consumption of a jailed server or whatever, just the overhead of each jail. I'm especially interested on CPU, memory and IO. For a few jails the overhead is negligible but imagine a server with 100 jails.

  • Getting back the old alt-tab windows switching behavior in Windows 7?

    - by Carlos A. Ibarra
    When you run more than 6 applications on Windows 7 and you press alt-TAB, icons representing the first 6 applications and the desktop appear on the first row of the grid and you can cycle with alt-TAB-TAB... through the 6 most recently used windows the usual way, but the 7th and other less recently used windows don't follow the same rules. Instead they get grouped together according to their application but disregarding whether they were recently used or not. This new behavior is mentioned here. I am very used to the old way of cycling and the new system is driving me crazy. I tend to have 20 or so windows open at one time and I frequently need to alt-tab to the 7th or 8th window on the stack but it doesn't work the same anymore. Does anyone know how to put back the old behavior, so that alt-tab-tab-tab... goes through the whole list in most-recent to least-recent order?

  • Intel HD 4000 and Nvidia GT 650 working together on laptop

    - by Juan
    My new win7 Acer notebook has i5 CPU with Intel HD 4000 and Nvida GT650 GPU. Obviously monitor is plugged to Intel HD. In Nvidia control panel I can configure PhysX but that doesn't help. Windows system rating shows high gaming experience and average/low windows aero experience. What does that mean? Does my laptop use nvidia for games/3d apps nad Intel HD 4000 for aero? Should I disable Intel HD in bios, but how to plug monitor to nvidia? Or should I leave everything like now because everything works as it suppose to work? Here is image capture of some states: http://oi47.tinypic.com/34p0qp4.jpg

  • Updating records with their subordinates via CTE or subquery

    - by Mike Jolley
    Let's say I have a table with the following columns: Employees Table employeeID int employeeName varchar(50) managerID int totalOrganization int managerID is referential to employeeID. totalOrganization is currently 0 for all records. I'd like to update totalOrganization on each row to the total number of employees under them. So with the following records: employeeID employeeName managerID totalOrganization 1 John Cruz NULL 0 2 Mark Russell 1 0 3 Alice Johnson 1 0 4 Juan Valdez 3 0 The query should update the totalOrganizations to: employeeID employeeName managerID totalOrganization 1 John Cruz NULL 3 2 Mark Russell 1 0 3 Alice Johnson 1 1 4 Juan Valdez 3 0 I know I can get somewhat of an org. chart using the following CTE: WITH OrgChart (employeeID, employeeName,managerID,level) AS ( SELECT employeeID,employeeName,0 as managerID,0 AS Level FROM Employees WHERE managerID IS NULL UNION ALL SELECT Employees.employeeID,Employees.employeeName,Employees.managerID,Level + 1 FROM Employees INNER JOIN OrgChart ON Employees.managerID = OrgChart.employeeID ) SELECT employeeID,employeeName,managerID, level FROM OrgChart; Is there any way to update the Employees table using a stored procedure rather than building some routine outside of SQL to parse through the data?
