  • How to Run PowerShell Commands on Remote Computers

    - by Chris Hoffman
    PowerShell Remoting allows you to run individual PowerShell commands or access full PowerShell sessions on remote Windows systems. It’s similar to SSH for accessing remote terminals on other operating systems. PowerShell is locked-down by default, so you’ll have to enable PowerShell Remoting before using it. This setup process is a bit more complex if you’re using a workgroup – for example, on a home network — instead of a domain.

  • ssh tunnel to a remote CUPS server

    - by drevicko
    There is a CUPS server beyond a firewall and I'd like to use it's printers. I have ssh access to computers that can access the CUPS server, and can get at the servers web interface by forwarding say port 1631. I cannot forward port 631 as I've not got root access to anything on the servers network. In Ubuntu's 'Printing' control panel, I can enter the address of a server, but I've not been able to connect through the forwarded port (localhost:1631, which is forwarded to the remote CUPS server's 631 port). Any ideas?

  • I don't have permission to access other drives

    - by mcjohnalds45
    After messing with the user accounts & names, I found I can't access my external drives without using sudo. So when I access one normally with cd "/media/john/FreeAgent Drive" I receive bash: cd: /media/john/FreeAgent Drive: Permission denied However, using sudo: sudo cd /media/john sudo ls -l It gives: drwx------ 1 john john 20480 Sep 24 10:45 FreeAgent Drive/ And id returns uid=1003(john) gid=1003(john) groups=1003(john), ... So I'm interpreting this is as "you are john, only john can access this drive, however, you cannot access this drive." I have tried sudo chown john:john "FreeAgent Drive" and sudo chmod o+rw "john/FreeAgent Drive"but I still can't access it.

  • Configuring SQL Server Express Edition for remote access

    - by rohancragg
    Originally posted on: http://geekswithblogs.net/rohancragg/archive/2013/07/24/configuring-sql-server-express-edition-for-remote-access.aspxI wanted to access SQL Express on my local machine from within a Client Hyper=V virtual machine on the same Domain. This article got me most of the way there: http://akawn.com/blog/2012/01/configuring-sql-server-2008-r2-express-edition-for-remote-access/ But it was a bit out of date. My steps were: Enable TCP/IP Protocol in SNAC Restart SQL Server Configure (Windows 8) Firewall to allow all Inbound for sqlservr.exe Footnote: I thought this might be relevant (nice to be able to script it): http://support.microsoft.com/kb/968872/en-us But the problem is that this is for fixed ports and not compatible with the (default) Dynamic Ports settings above.

  • How to set up dual wired and wireless connections?

    - by Col
    My laptop has both wireless and a wired connection capabilities. Can I connect to a router A using wireless and a separate router B using wired ethernet at the same time without having to switch back and forth? Thanks for replying so quickly. I wish to connect to two separate networks. The wireless connection is to router A which is connected to broadband internet. The wired connection is to router B which I wish to share files and a printer on 1 or 2 other desktops also using wired connections on B and maybe using synergy to have only one keyboard and mouse for 2 desktops. The wireless laptop is the only one required to have internet access.

  • Does MS Access 2010 have Tif image control display issue?

    - by ChuckB
    We run MS Access as the front end for most of our business. When we upgraded from Access 2000 to Access 2003 the image control we used to print out Tif images failed to load Tifs anymore. A bit of Googling showed that MS did this intentionally and I'm wondering if the problem still happens in Access 2010. Can someone with a downloaded copy drop an image control on an Access 2010 form or report and try to get it to display a Tif file?

  • Does Guest WiFi on an Access Point make any sense?

    - by uos??
    I have a Belkin WiFi Router which offers a feature of a secondary Guest Access WiFi network. Of course, the idea is that the Guest network doesn't have access to the computers/devices on the main network. I also have a Comcast-issues Cable Modem/Router device with mutliple wired ports, but no WiFi-capabilities. I prefer to only run one router/DHCP/NAT instead of both the Comcast Router and the Belkin Router, so I can disable the Routing functions of the Belkin and allow the Comcast Router to But if I disable the Routing functions of the Belkin device, the Guest WiFi network is still available. Is this configuration just as secure as when the Belkin acts as a Router? I guess the question comes down to this: Do Guest WiFi's provide security by 1) only allowing requests to IPs found in-front of the device, or do they work by 2) disallowing requests to IPs on the same subnet? 1) Would mean that Guest WiFi on an access point provides no benefit 2) Would mean that the Guest WiFi functionality can work even if the device is just an access point. Or maybe something else entirely?

  • cascading combo box causing empty fields in next record

    - by glinch
    Hi there, I'm having problems with a cascading combo box. Everything works fine with the combo boxes and the values get populated correctly. Private Sub cmbAdjComp_AfterUpdate() Me.cboAdjOff.RowSource = "SELECT AdjusterCompanyOffice.ID, AdjusterCompanyOffice.Address1, AdjusterCompanyOffice.Address2, AdjusterCompanyOffice.Address3, AdjusterCompanyOffice.Address4, AdjusterCompanyOffice.Address5 FROM" & _ " AdjusterCompanyOffice WHERE AdjusterCompanyOffice.AdjCompID = " & Me.cmbAdjComp.Column(1) & _ " ORDER BY AdjusterCompanyOffice.Address1" Me.cboAdjOff = Me.cboAdjOff.ItemData(0) End Sub The secondary combo box has a row source query: SELECT AdjusterCompanyOffice.ID, AdjusterCompanyOffice.Address1, AdjusterCompanyOffice.Address2, AdjusterCompanyOffice.Address3, AdjusterCompanyOffice.Address4, AdjusterCompanyOffice.Address5 FROM AdjusterCompanyOffice ORDER BY AdjusterCompanyOffice.Address1; Both comboboxes have the same controlsource. Everything works fine and dandy moving between records and the boxes show the correct fields for each record. When i use the first combo box, and then select the appropriate option in the second combo box, everything works great on the specific record. However when I move to the next record, the values in the second combo box are all empty. If i close the form and reopen it, and avoid using the cascading combo boxes all the values are all correct when i move between records. Somehow using the cascading combo boxes creates a conflict with the row source of the secondary combo box. Hope that is clear! Have been rummaging around for an answer but cant find anything. any help would be greatly appreciated. Thanks Noel

  • Combo-box values automatically update

    - by glinch
    Hi all, hopefully somebody can help The table structure is as follows: tblCompany: compID compName tblOffice: offID, compID, add1, add2, add3 etc... tblEmployee: empID Name, telNo, etc... offID I have a form that contains contact details for employees, all works ok using after update. A cascading combo box, cmbComp, allows me to select a company, and inturn select the appropriate office, cboOff, and updates the corresponding tblEmployee.offID field correctly. Fields are automatically updated for the address also cmbComp: RowSource SELECT DISTINCT tblOffice.compID, tblCompany.compID FROM tblCompany INNER JOIN AdjusterCompanyOffice ON tblCompany.compID=tblOffice.compID ORDER BY tblCompany.compName; cboOff: RowSource SELECT tblCompany.offID, tblCompany.Address1, tblCompany.Address2, tblCompany.Address3, tblCompany.Address4, tblCompany.Address5 FROM tblCompany ORDER BY tblCompany.Address1; The problem I am having is that when i load a new record how to retrieve the data and automatically load the cmbComp and text fields. The cboOff combo box loads correctly as the control source for this is the offID I imagine there must be a way of setting the value on opening the record? Not sure how though. I dont think I can set the controlsource cmbComp or text fields, or can I? Any help/point in the right direction appreciated, have been searching for a way to do this but cant get anywhere!

  • Can an iPhone/iPod Touch application open a port for remote communication without jailbreaking?

    - by Derrick
    I'm researching remote control testing for an app that'll be installed on the new iPod Touch and can't tell for certain from everything that I've read whether or not an installed app can or can't open any ports for remote test instructions (that's a mouthful : ) We created something like this for the Android using adb port forwarding and telnet, and it worked really well. Is there any chance something similar could be done on an iPhone or iPod without jailbreaking??

  • isPostBack as Query Parameter

    - by Steven
    I created an ASPX page with search controls to the left bound as controls for an AccessDataSource. I want the data grid to be blank on the first calling of the page, but show the results for subsequent page loads. I plan to achieve this by putting [pFirstRun] = False as my first WHERE condition with the parameter pFirstRun tied to the value isPostBack. How do I achieve this? Alternatively, is there a better way to achieve this goal?

  • No Internet access while being connected to VPN using Cisco VPN Client 5.

    - by szeldon
    Hi, I have an access to corporate VPN using Cisco VPN Client 5.0.00:0340, but when I'm connected to it, I don't have an Internet access. I'm using Windows XP SP3. As it was suggested here http://forums.speedguide.net/showthread.php?t=209167 , I tried to enable "Allow local LAN Access" but it doesn't work. I also tried a second solution - deleting entry using "route" command, but it didn't help. I used "route delete 192.168.100.222". It's a third day of my attempts to solve this issue and I don't have an idea what else to do. I'm not very experienced in VPN stuff, but I know something about networking. Basing on my knowledge, I think that it's theoretically possible to achieve Internet access using my local network and only corporate stuff to be routed using VPN connection. I think that theoretically this should look like this: every IP being inside by corporation - VPN interface IP every other IP - my ethernet interface I've tried many possibilities of how to change those routes, but neither of them work. I'd really appreciate any help.
