Hi all! I want to deny my internet connection's download properties for all port. I mean i want to make just upload. is it possible? Thank you very much for your help, already now.
I have a newbie security related question.
Should port 25 (smtp) be blocked by firewall on my server?
Or will doing so mean that i cannot send any mail at all?
does serving files like images via subdomain speed up loading speed. i read somewhere that static files like images, java script served via cookieless domain does mean something regarding website speed.
I wish to use vagrant and possibly VeeWee to construct and maintain virtual machines to automate some testing of servers etc.
I am having problems getting them up and running on windows. Is there any are there any takes-nothing-for-granted setup blog posts or instructions anywhere?
I live in a Microsoft world so all this Ruby/Git is new (and exciting!) to me but it does mean that I could do with everything being spelled out to me in excruciating detail!
Cheers
I am changing host and my new host said:
Meanwhile, in order your newly registered hosting account to function correctly until the transfer is ready, you can change the NS records to the following:
ns1.itahost.com
ns2.itahost.com
What does this mean?
I have multiple PuTTy sessions open to my SunOS 5.10 server, and I am using ksh, and SOMETIMES the command history is shared among the different sessions and SOMETIMES it is not. I cannot figure out what determines whether it is or is not shared. By shared what I mean is that a command run in one session will be seen as previous command run in another session.
I prefer it not to be shared, is there a config setting for that?
Thanks
I am using mobile dial up on ubuntu.
However, SOMETIMES even though I am connected to the ISP, I do not have any entries in /etc/resolv.conf. I often restart network-manager or networking hoping it will change but normally it doesn't do any good. and by connected I mean I can see that the network notification icon has switched to a few bars indicating connectivity).
Anyone know a good solution around this?
Is it possible to set Microsoft Word to display some text left-aligned and other text right-aligned on a single line? Here's an example of what I mean:
| Chickens, turkey and duck 30 |
| Cows 240 |
| Pigs and boar 83 |
| Sheep Not applicable |
where the vertical lines denote the sides of the page.
The full justify option won't work because I don't want anything in the middle of the lines. The table of contents option has the formatting I want, but only supports page numbers, which does me no good.
As I understand it if I run the command gpasswd -A username directoryname I assign administrator privileges to username for the directory directoryname. This means that username is able to add new members to the group for directoryname without root privileges. Does this also mean that username belongs to the group or do I need to add username to the group using the commands usermod, gpasswd -a or gpasswd -M
Recently I encountered a big problem: Blend 4 always crashes immediately after a splash screen ends. No error numbers mentioned, just a crash window saying "Blend has been crashed, debug or close".
Is anybody else familiar with that problem? I tried to get some help from Google but there were no relevant references.
I Clicked "Debug" and JIT Debugger was opened, it threw "FataExecutionEngineError" exception... What does it mean?
Tomcat 6 (as a windows service) seems to have a 'Start Mode' with options of 'java, jvm or exe' which can be set via the Tomcat Monitor (system tray icon).
if I set this to 'java', I can see a forked 'java.exe' process for tomcat, if I chose either of the other two, I dont see a separate process.
Anyway, would like to know if anyone has any information about what these settings mean and which one would be most appropriate in production.
Many phones has the functionality to listen to FM radio without connecting to the internet. Just wondering that how can I do this on a computer? Please give me some advices, thanks a lot.
Sorry guy I understand this question is not programming related. For a computer I mean a notebook which already has the wireless and Bluetooth, and these two combination shall be able for a notebook to perform this functionality.
I'm testing Windows 8 RP. Installed tens of apps from market. What I wanna know is, is there any way to save (or maybe sync with Windows Live account) installed app list, and install these saved applications in future - RTM version of OS?
I mean, somehing like on Apples' devices - icloud features function that I'm talking about. You can install apps on iPhone and sync with iCloud account. Then you can re-install these apps on another device, which signed in with your login into icloud.
Hi All,
Is it possible to hyperlink a url in excel automatically. I mean when the cell starts with something like http or www can I hyperlink that. Currently, I have to hit enter in the cell value in the formula bar to make the link as clickable. Also if I change the value in the cell, the link doesnt get refreshed until I hit enter. Is there a way in excel where it will automatically detect and apply a hyperlink.
I am in charge of production servers serving static content for a website. Those servers are constantly being crawled by bots looking for potential exploits (which isn't that much of a problem security-wise because no application can be reached behind the web server) but
generates thousands of 404 per day, sometimes per hour. I am looking into ways of blocking those requests but it's tricky (you want to make sure you don't block legitimate traffic and these bots are becoming more and more clever at looking like they're legit) and is going to take me a while to find an acceptable solution.
In the meantime I would like to reduce the performance impact of serving those 404 pages. Indeed we're using nginx which by default is configured to serve it's 404 page from the disk (This can be changed using the error_page directive but in the end the 404 will either have to be served from disk or from another external source (e.g. upstream application which would be worst)) which isn't ideal.
I ran a test with ab on my local machine with a basic configuration: in one case I echo a message directly from nginx so the disk isn't touched at all, in the other case I hit a missing page and nginx serves its 404 from disk.
server {
# [...] the default nginx stuff
location / {
}
location /this_page_exists {
echo "this page was found";
}
}
Here are the test results (my laptop has Intel(R) Core(TM) i7-2670QM + SSD in case you're wondering why they are so high):
$ ab -n 500000 -c 1000 http://localhost/this_page_exists
Requests per second: 25609.16 [#/sec] (mean)
$ ab -n 500000 -c 1000 http://localhost/this_page_doesnt_exists
Requests per second: 22905.72 [#/sec] (mean)
As you can see, returning a value with echo is 11% ((25609-22905)÷22905×100) faster than serving the 404 page from disk. Accordingly I would like to echo a simple 404 Page not Found string from nginx.
I tried many things so far but they all failed, essentially the idea was this:
location / {
try_files $uri @not_found;
}
location @not_found {
echo "404 - Page not found";
}
The problem is that as soon as the echo directive is used, the http response code is set to 200. I tried changing that by doing error_page 200 = 400 but that breaks the configuration.
How can I serve a 404 page directly from nginx? (without hacking the source which may be might next step)
I'd like to make a backup/image of my machine, so that I may install it if i ever need to.
What I mean by image is a snapshot of all of my programs, settings,files, everything, i think this is referred to as a ghost image.
I want to be able to restore so I do not have to reinstall everything again.
Does the backup/restore utility in Windows Server 2008 R2 do this?
I use a laptop and I am docking and undocking frequently. Often when I connect to another machine using remote desktop, the screen size gets messed up when I dock again. By "messed up" I mean that it stays the size of my lap top screen (wide screen ratio). Clicking maximize will not get it to go full screen.
Any ideas how I can reset this (other than a reboot).
I have a brother mfc-5440cn and tried to adjust the vertical alignment with the result that the printing quality now is very poor. The printer prints a small schadow next to each letter :-(
I tried to re-adjust the alignment, but for the 600dpi settings, there is no pattern that matches the 0-pattern (you know what I mean when you've once adjsuted a brother printer :-)
Is there a way to make a factory reset?
I've red this article from howtogeek, but it didn't explain this one which is placed in the target portion when you right click on windows explorer and click properties:
%windir%\explorer.exe shell:desktop\Inbox
And why does local disk E: shows up when I have this one:
%windir%\explorer.exe shell:E:\FINAL SAVE DATA
I don't really get the code, especially the part in shell: desktop\Inbox.
What's that supposed to mean. How do I change it so that when I click on the Windows Explorer shortcut, I get to see this location:
E:\FINAL SAVE DATA
We would like to synchronize our users or backup their laptops to the data center – looking for suggestions/alternatives to synch them to the data center where they don’t have to know about it. Blue sky like to haves:
• Don’t want VPN but needs to secure
• Admin can access all files
• Global dedup
• Select file types only – MS Office, PSTs, PDFs
• Incremental change only
• Right now 60 users but needs to scale (all Windows7 64 bit)
• Can allocate budget if have to
Don’t mean to be vague but hoping to get some proven places to start.
I've ran into this cryptic statement for SQL Server: Files Per Database 32,767. What does that mean exactly? Is there a maximum number of tables for a given version of SQL Server. We try to support SQL Server post 2005 32-bit and 64-bit.
So if anyone has a handy dandy table they use to figure out how many tables they can have per DB for Microsoft SQL Servers I'd heartily appreciate seeing it.
I found this site to compare CPU's. http://www.cpubenchmark.net/high_end_cpus.html
What wasn't clear is how the benchmark for multiple core processors is calculated. If one CPU has 4 cores (such as Intel Core i7 which comes in 2, 4, and 6 core versions: http://en.wikipedia.org/wiki/Intel_Core_i7#Core_i7), does that mean that the benchmark should be double that of the version that has 2 cores (assuming the same clock frequency)?
I wonder if there is an utility to read and print a (binary) file, shifted by some amount of bits (i mean, it should accept amounts, which are not divisible by 8).
.. something like dd (and its skip option), but bit-wise, instead of byte-wise.
(If you think that there is no such thing, and are going to implement it here, please use C.. i have my own bit-shifting thing for strings, written in Python, but it is surely relatively slow as hell)
