• Any tool to check which ports/protocols firewalls prevent?

  - by Jus12

  Suppose I have a setup as: host_1 --- Firewall_1 --- Internet --- Firewall_2 --- host_2 I need to check which ports are open on host_2 from host_1 (which may be blocked by either firewalls) If there a tool that comes in two parts (one running on host_1 and other on host_2) that does this for me? It should be something like: 1 Listen to all ports on host_2 2 Try to connect to every port on host_2 from host_1 3 Give a report what ports are allowed.

• What's the difference between Defaults and Properties when changing cmd.exe or PowerShell's settings?

  - by mmm bacon

  I want to change the font used by both cmd.exe and PowerShell. When I right click in the window border, I see both Defaults and Properties: What's the difference? One would think Defaults was for all sessions, and Properties was for the current session. However, changes to Properties are persisted even after relaunching cmd.exe. Another problem is that changing the font in either Defaults or Properties doesn't actually change the font. This is on Windows 8.

• Restart browser on error

  - by billfredtom

  Is there a way to restart a browser (Internet Explorer, Firefox, etc) automatically upon receiving an error such as a DNS error or Page not found? Background: It is for a web based signage application that has intermittent network drop outs, therefore if there's no internet, and the sign tries to go to the next page, an error occurs on browser, and we get one big ugly sign. We need a way to either restart the browser, or customise displayed error messages to use javascript to try redirection to the live sign again.

• Windows repair console, impossible?

  - by Daniel

  I found an old Windows XP SP2 in my -trash- cd can and tried it on a 30 GB FAT32 partition. Installation went fine till the copying operation was completed and XP asked for reboot. After that either it starts over again or throws invalid disk. Starting over is an infinite loop the only way I see is to choose the "Repair console" but I'm not used to a DOS box. Can anyone help me through this harmful installation?

• Where's my Open-With gVim context menu option in Windows 7?

  - by David Mackintosh

  I have gVim installed. Under Vista and XP, this offered me an addition to either the object context menu of "Edit with gVim", or an addtion to the "Open With" context menu of "gVim". This would let me send arbitrary files to gVim for editing. Under Windows 7 64-bit, I have installed gVim -- twice, as it happens -- and there's no menu item. How do I add an option to send arbitrary files to gVim for viewing/editing?

• Can I disable comments by default on my YouTube videos?

  - by Philip Durbin

  Comments are unfortunately always automatically enabled when I upload a video to YouTube either via their website or iPhoto, but more often that not I later manually disable comments for each uploaded video by following the steps from the "comments on my videos" section of YouTube Help. I would much rather have comments automatically disabled, that is to say, disabled by default, for all of my uploaded videos. Is this possible? I couldn't find a setting for it.

• Does Failed Data Bus Stress Test mean bad RAM stick or motherboard?

  - by samjetski

  I have encountered an error when running a memory test. Does a failed "Data Bus Stress Test" mean a problem with the RAM stick, or with the motherboard/chipset? Or could it be either? (ie: is the data bus it's refering to in the RAM stick, or on the motherboard) Note: I am using the Dell Diagnostics Utility (on a bootable partition).

• Can I query DHCP server for getting mapping of MAC to IP address (I have admin rights)?

  - by Kazoom

  I need to know the MAC to IP address mapping stored on DHCP server. I don't want to use arp cache as that would require me to either broadcast ping (which is not allowed on windows) or ping the all possible ip address of subnet( which takes lot of time). I am sure that DHCP server stores the mapping of MAC to IP, how can i use that information, to map MAC to IP address?

• iPhone surfing via USB... without wifi or data plan?

  - by Philipp Lenssen

  I bought an iPhone in China, where it is manufactured without Wifi. (I would have to switch carriers to sign up for a data plan as my current Chinese carrier doesn't support surfing either... if possible I want to avoid getting yet another card though.) Can I somehow surf with the iPhone Safari while USB-connected to my net-enabled laptop? Thanks!

• Windows 7 boot problem

  - by nijikunai

  My system doesn't boot at all, upon starting it takes me to the Windows Error Recovery screen saying "Windows failed to start, a recent software or hardware change might be the cause" and gives two options Launch System Repair (Recommended) Start Windows normally But neither options work, upon clicking either of them, some progress bars get displayed and the screen just freezes on "Starting Windows". I tried booting from the Windows 7 disk but it too freezes on the "Starting Windows" screen. I even tried booting from ubuntu, slax linux, but they don't work too.

• Setting background color in gvim

  - by petersohn

  I use a terminal with white text on black background (I just like it better), so I wrote the following line in my .vimrc file: set background=dark However, gvim has black on white text. How do I do either of the following: Set the background of gvim to black Check in .vimrc if I'm using gvim I tried this: I started up gvim, and typed echo &term. The answer was "builtin_gui". So I wrote the following into .vimrc: if &term == "builtin_gui" set background=light else set background=dark endif Somehow, it didn't work.

• Make Thunderbird show message list like Outlook?

  - by wag2639

  Does anyone know how to change the layout (either option or extension) for Thunderbird 3 to make it look like the default layout in Outlook? Basically, in Vertical View, I can get my Folders on the left, next to a 2 line listing of each message (Sender and Time line 1, Subject on line 2), and Message Pane on right? If not, I'll also take as Notes links to guides on how to make my own extension.

• Can the mysql slow query log show milliseconds?

  - by Chase Seibert

  The mysql slow query log shows query time in whole integers. # Query_time: 0 Lock_time: 0 Rows_sent: 177 Rows_examined: 177 SELECT ... # Query_time: 1 Lock_time: 0 Rows_sent: 56 Rows_examined: 208 SELECT ... There was a microsecond patch to allow mysql to be configured to log queries that take longer than X microseconds to run. But is there a way to have the log output the query time in either milliseconds or microseconds?

• Address book software that knows people share addresses

  - by Benjol

  I'm a bit frustrated with Outlook and Google contacts, as neither understand that people share addresses, or that one address can represent several people. So you either have crappy custom fields like "Bill's mobile", "Jane's mobile", or you have a Bill and a Jane contact, and you have to keep the address updated between the two. Are the any decent, and simple, address book applications out there which have this kind of intelligence? Note: this is for home use, I don't need to do professional 'contact management'.

• ASA and cisco vs NSA sonic firewall

  - by Lbaker101

  Currently I’m trying to structure our network to fully support and be redundant with BGP/Multi homing. Our current company size is 40 employees but the major part of that is our Development department. We are a software company and continued connection to the internet is a requirement as 90% of work stops when the net goes down. The only thing hosted on site (that needs to remain up) is our exchange server. Right now i'm faced with 2 different directions and was wondering if I could get your opinions on this. We will have 2 ISPs that are both 20meg up/down and dedicated fiber (so 40megs combined). This is handed off as an Ethernet cable into our server room. ISP#1 first digital ISP#2 CenturyLink we currently have 2x ASA5505s but the 2nd one is not in use. It was there to be a failover and it just needs the security+ license to be matched with the primary device. But this depends on the network structure. I have been looking into the hardware that would be required to be fully redundant and I found that we will either of the following. 2x Cisco 2921+ series routers with failover licenses. They will go in front of the ASAs and either connects in a failover state or 1 ISP into each of the 2921 series routers and then 1 line into each of the ASAs (thus all 4 hardware components will be used actively). So 2x Cisco 2921+ series routers 2x Cisco ASA5505 firewalls The other route 2x SonicWalls NSA2400MX series. 1 primary and the secondary will be in a failover state. This will remove the ASAs from the network and be about 2k cheaper than the cisco route. This also brings down the points of failure because it’s just the 2x sonicwalls It will also allow us to scale all the way up to 200-400 users (depending on their configuration). This also makes so the Sonic walls. So the real question is with the added functionality ect of the sonicwall is there a point in paying so much more to stay the cisco route? Thanks!

• Easy to use web-based reporting tool

  - by SuperFurryToad

  I'm looking for recommendations for an easy to use reporting/business intelligence tool that can interface with an sql server or access database. It can be web-based or a desktop tool. Ideally it would be freeware or low cost, and easy to use for users who are not that technically savvy (below the level of someone who can generate reports and complicated queries in Access). Any tools I've seen so far (such as Crystal Reports) are either too expensive or too complicated to use for non-power users.
