That Nasty Samba Vulnerability Is Now Patched in All Supported Ubuntu Releases by https://is.gd/suMzeI

You might have read the news this morning about a wormable code-execution bug discovered in the Samba free software re-implementation of the SMB/CIFS networking protocol, which existed in Samba for more than 7 years.

The Samba team managed to quickly patch the critical vulnerability that was discovered to affect over a hundred thousand Linux and UNIX machines running Samba, which is usually used to provide file and printing sharing services, allowing users to connect to Windows shares on a network.

The Samba 4.6.4, 4.5.10 and 4.4.14 patched versions have been released, and are available for download from the official website or via ours if you want to compile it on your GNU/Linux distribution. Canonical already patched Samba in all supported Ubuntu releases, and other GNU/Linux distributions will soon receive the patch.

OK, first at all, you need to find out what IP’s are used on the routers of that LAN. You could use some tracing tools like the Advanced IP Scanner which you could download free from: http://www.advanced-ip-scanner.com/

You have to key in the IP Range of the LAN system like 192.168.1.1 to 192.168.1.254. This you could find (if you didn’t know already) using in Windows Command Prompt (CMD) or PowerShell the command: ipconfig /all

How to extend your home wi-fi lan using the Airport Extreme when the Netgear router hasn’t a specific option for that

7 Replies

This is the situation: I have a Netgear wi-fi router which has not the option to extend the wi-fi lan and two rooms in my house where it was not possible to use computers or external hard disks due to the weak wi-fi signal in there. The other available stuff I have is an Apple Airport Extreme with the right features to extend the existing wi-fi lan.

After many different configuration tests I was not able to configure correctly the wi-fi lan to improve the signal and cover all my house. Then I decided to buy a couple of used powerline ethernet adapter for about 30.00 USD and I put one of them near the area I wanted to cover with my wi-fi lan.

Then I connected the Airport Extreme to the adapter located near the low signal area and I was able to solve my problem configuring the lan in this way:

1- I reserved a fixed IP on the Netgear router for the Airport Extreme and I added that specific IP in the DMZ list:

2- I put the Airport Extreme in the Bridge mode and chose Ethernet as data connection:

3 – I cloned the configuration of the Netgear wi-fi on the Airport Extreme. In particular I assigned to the new wi-fi lan the same broadcasting name to the main one:

4 – I restarted the Netgear router and I had a strong wi-fi signal into all my house.

I know that the solution I found it is not orthodox but it is cheap especially when you do not want to spend money for a new professional router when the “old” one is still brand new.
