networking - Why is my connection refused when port-forwarding?

This question is related to this: Application / Device setup for remote network connections


I have a 2wire 3801HGV router and I made some firewall settings to open some ports on one of my connected devices.


So now actually it will say:


Pinholes


external pin-holes (186 available):
pinh[0]: id 5, proto 6, sess tout 86400, pinh tout 0, arg 0 natpt|user
  l: 192.168.1.253:80, n: **.**.***.**:80
pinh[1]: id 6, proto 17, sess tout 600, pinh tout 0, arg 0 natpt|user
  l: 192.168.1.253:80, n: **.**.***.**:80
pinh[2]: id 7, proto 6, sess tout 86400, pinh tout 0, arg 0 natpt|user
  l: 192.168.1.253:9000, n: **.**.***.**:9000
pinh[3]: id 8, proto 6, sess tout 86400, pinh tout 0, arg 0 natpt|user
  l: 192.168.1.253:18004, n: **.**.***.**:18004
pinh[4]: id 9, proto 17, sess tout 600, pinh tout 0, arg 0 natpt|user
  l: 192.168.1.253:9000, n: **.**.***.**:9000
pinh[5]: id 10, proto 17, sess tout 600, pinh tout 0, arg 0 natpt|user
  l: 192.168.1.253:18004, n: **.**.***.**:18004

Of course instead of those * it shows my actual, public IP.


If it says that, then how come when I go to http://www.canyouseeme.org/ and I'm checking ports 80, 9000, and 18004 it says



Error: I could not see your service on **.**.***.** on port (80/9000/18004)


Reason: Connection refused

keyboard - Is there any utility/method to change Windows key bindings to type rare chars to currently empty bindings?

I'm currently typing this post with my windows XP machine and (Spanish) keyboard, and I'd like to add some extra symbols to my text. I could open the "char map" windows utility, look for the desired symbols, and paste them. But I'd like something quickier. For example, when I'm using my OSX Mac at work, I can easily add a ©, ™, ® or similar symbols, just pressing some weird ALT-GR + G / H / J, key combinations. In my (Spanish) keyboard mapping, these combinations are empty, as they don't produce any char at all, which, on the other hand, is perfectly normal and desirable. So, I thought: Why couldn't I add some extra key mappings on top of my currently empty ALT-GR + G/J/H Keys in my Spanish keyboard, and thus, being able to quickly type these special symbols? So that's my question: Is there any utility/method to achieve that effect under windows? (My version is XP). I've even googled this for some time but no luck. I've been a long term Hot...

virtualization - How to select paravirtualization interface in VirtualBox?

Given a windows 8 host system (Intel Core i5) and a Linux Fedora host, I would like to determine the optimal setting for the paravirtual interface. Options are none Default Legacy minimal Hyper-V KVM This page suggest the selection is only based on the guest system: The biggest change in VirtualBox 5.0 is the introduction of paravirtualization support, bringing higher performance and time-keeping accuracy to supported guest operating systems (Hyper-V on Windows and KVM on Linux). Is that correct? Answer The VirtualBox Manual , in the section titled Paravirtualization providers explains very clearly when each should be used (emphasis added): Minimal: Announces the presence of a virtualized environment. Additionally, reports the TSC and APIC frequency to the guest operating system. This provider is mandatory for running any Mac OS X guests. KVM: Presents a Linux KVM hypervisor interface which is recognized by Linux kernels starting with version 2.6.25. VirtualBox's implementati...

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...

security - How is Linux not prone to viruses, malware and those kinds of things?

How is Linux protected against viruses? This question was a Super User Question of the Week . Read the blog entry for more details or contribute to the blog yourself Answer Well, it factually is not... it's just less subject to hackers developing viruses that target Linux systems. Consumer grade computers usually run on Windows and thus, when targeting a wide audience, Windows is the way to go. Don't misunderstand Linux and viruses, there definitely ARE Linux viruses. Some distros have additional protection layers such as SELinux (See here ) in Ubuntu for example. Then there's the default firewall and the fact that alien files don't automatically have permission to be executed. Specific execution permission has to be granted before execution is possible. (See here ) Then there are several other factors that make Linux a hard place to be for viruses usually non-root users on linux systems have no to little executable files at their disposal that would allow for virus...
