Determine Computer Name By IP Address Through ARP

We recently had to determine is a particular computer was up on the network. Using the command “arp -a” gaves us all the IPs being used on the network. Next was to ping the ip to resolve the name. We used the following command which didn’t work.

“ping 192.168.0.122 -a”

This pinged the machine and told us it was up; however, we needed the machine name. The next command gave us the computer name.

“ping -a 192.168.0.122”

Safe To Update Adobe Flash Player – Not Really!

Had another employee ask to me upgrade his Flash Player. He got a warning that the Flash Player was out-of-date. I actually have worked in Flash for years and appreciate all that it can do, but from a security stand point it can be too powerful.

When I got to his machine I saw the Adobe Flash Player Update page; however, the URL was not Adobe.com.

The URL was for “http://etaigwebulvar.com/..”. Clearly not Adobe.

Be careful with Flash Player updates.

Protecting From WannaCry Ransomware

We have been diligently verifying our customers computer systems are up-to-date and protected from the lastest round of Ransomware called “WannaCry”.

Not sure exactly what patches needed to be applied I found a good page from SolarWinds the lists the appropriate patches for a given Operating System.

https://support.solarwindsmsp.com/

Microsoft’s Update Catalog allows you to download the the “.MSU” patches. Microsoft recommends using Internet Explorer to download and install the patches. You may need to set downloads to “enable”. In Internet Explorer Tools, under the Security tab, select “Custom Level.”. Scroll down till you see “Download” and click enable.

For antivirus we have been using Vipre. We received a email from Virpe stating the were already protecting customer before the virus was released. That will save us a considerable hassle. Here is the link the sent us.

This list above is good to know the patches.  The next step was to disable “SMB1”. I logged onto the clients server and open Powershell as an administrator, and ran the following commands.

sc.exe config lanmanworkstation depend= bowser/mrxsmb20/nsi
sc.exe config mrxsmb10 start= disabled

All of these updates required a reboot of the server.

Godaddy Hosting – upload_max_filesize – How Do I Increase My Upload Size

My Joomla install told me the upload_max_filesize is 2M. I changed this in my PHP5.ini file on the server, but this had no effect. I learned later that this takes time to become in effect.

A faster way is to “PHP Selector”. You will see “Switch to PHP Options” in the upper-right. Click on this.  Click on the number next to “upload_max_filesize” and change it to what you want. Godaddy said to keep it under a Gig or you will have issues.
