Iptables is not the best tool for packet capturing and I am not sure that capturing packets will answer your (routing) questions. You can use one of many tools, wireshark, snort, or tcpdump (to name a few). Your router may be able to track / log this as well. The details of packets is moderately complex and somewhat lengthy to expalain. Take a look at the ...

He we noticed the same problem: Linux 3.2 kernel on Ubuntu 12.04 worked without any problems, Linux 3.13 on Unbuntu 14.02 had the same problem. I am not sure if this is really a bug in the kernel, to me it looks more like a problem with selective ACKs (SACK). You can workaround the problem by disabling TCP SACK with: sysctl net.ipv4.tcp_sack=0 This worked ...

I suspect that your relatively new device is not covered in the relatively old 12.04 kernel. I suggest you get a temporary internet connection.

I've been using this method for a while to share between 3 android devices (Nexus 7 , Nexus 9 and Desire 816) as well as the odd laptop and it works without a hitch on Ubuntu 14.10 using unity. I think the main difference and the only change you may need to make is changing the connection type to ap as described in the guide i linked.

Unless you can find documentation about the camera indicating that it uses a standard for wireless such as bluetooth or wifi, it probably isn't compatible with anything else.

"Figured out" why the -Of didn't work.

I suggest that you see this answer and review the steps you made to set port forwarding on Linux.

You will have to enable the Port Forwarding in your High Speed Modem or Personal Router (if you have one). Log into the admin portal of your Router/HS Modem by using http://192.168.2.1 (may be 1.1 or something else as per your network range) and look for Internet Option. Setup the rule to forward the port 22 traffic to your local server. This will make ...

I confirm that net.ipv4.ip_forward=1 in /etc/sysctl.conf is correct way to keep forwarding across reboots. I suggest to look into /etc/sysctl.d/* files if there is an override to 0 somewhere.

It could be worth mentioning (even if it's probably not the case here) that if you're suddenly getting this error after renaming a folder or attempting to access a new one, you might have forgotten that you actually have to specify server-side what folders are shared and what aren't in /etc/exports -- this was the issue in my case. After you've modified ...

You should first ensure that the /etc/network/interfaces file contains at least the loopback interface configuration: auto lo iface lo inet loopback Next, if you have any auto stanzas and the interfaces might not be available at boot, you can replace auto with allow-hotplug to prevent upstart from waiting for them to be brought up (i.e. replace auto eth0 ...

I use the US archive mirrors at us.archive.ubuntu.com, the security updates at security.ubuntu.com, and also pull in extras (extras.ubuntu.com) and PPAs (ppa.launchpad.net).

I did a little searching and found some answers, not quite identical but should work, it's supposed to be "easy" using the Ubuntu GUI tools.

You could just test it in a virtual box of Ubuntu. That way you would have full control of network seting and there is also minimal risk of corruption

Instead of using 192.168.171.1, use 192.168.171.2. In VM 10, if you click on Edit, Virtual Network Editor, select VM8, under VMnet Information, select NAT, click on NAT Settings and there you'll find what your GW IP address is set to. When you find it, adjust your "eth0" gateway IP to that IP address.

Please confirm port forwarding which was done is working. If internal machine is working fine then it will refer local ip of the machine directly to access to machine on the port 22 If external ip couldn't ssh to the machine it could be a problem with port forwarding Telnet to the your external ip and check whether it connects to your local ip machine.

Many modern computer components contain thermal sensors, including but not limited to the CPU, hard drive, and even motherboards, although to be fair, motherboards did it first. Display cards may or may not include them but they should as they are usually the first to die from overheating. That said, it has never been my experience that commonplace network ...

Why do you need to check the temperature of your network card? Your network card may not have a temperature sensor, (I know that my somewhat older PCI network adapter doesn't) but if it does, and Hardinfo isn't reading it, you might want to try Psensor. Somewhat off topic, but why are you concerned about your network card's temperature?

Backports installs the networking drivers from a newer kernel, 3.16, for example, into an earlier kernel, in your case 3.13. Since you can select which drivers to install and not install all the wireless drivers that you don't need, 'defconfig ath10k', if you have two devices, you run the risk of installing conflicting cfg80211 and mac80211 pieces, as you ...
