I need to verify the network speed between to servers. I need to verify that the gigabit connection actually is gigabit when the servers are under heavy multiple channel communication. I suspect there are defective networking hardware (cable, switch, firewall) between the two servers and I need to proof that. Connect to the server via RDP. Download iperf utility. Make sure that the source server has opened port 5201 in Windows firewall or temporary disable firewalls on both servers. Put the utility to C: disk on the source server, run Command Prompt with Administrator, go to C: and execute the following: C: iperf.exe -s. You need to have a clear picture of all the networking hardware between the client and the SQL Server, for example: Web Server: Network Card(s)-Local Hub-Cisco Firewall-Network Card(s)-SQL Server. Then we need to capture simultaneous network traces from all intermediate server(s)/hardware(s) along with the client and SQL server.
While fighting working with a sysadmin group to get SFTP working between two servers, I want to be able to check ports and make sure the problem isn't the way I configured the software.
So it seems like there would be some utility I could install on both servers that would scan ports open between the servers and show what's open between the two. Muserver scf season 3 ep 2 full episode.
I've been searching, but everything about finding open ports is about port scanning the current server, not trying to find open ports to another.
