Do you need to check the connectivity between your server and your customers? Do you have different customers with different OS? Take a look to iperf.
From https://iperf.fr/:
Iperf features
- TCP
- Measure bandwidth
- Report MSS/MTU size and observed read sizes.
- Support for TCP window size via socket buffers.
- Multi-threaded if pthreads or Win32 threads are available. Client and server can have multiple simultaneous connections.
- UDP
- Client can create UDP streams of specified bandwidth.
- Measure packet loss
- Measure delay jitter
- Multicast capable
- Multi-threaded if pthreads are available. Client and server can have multiple simultaneous connections. (This doesn't work in Windows.)
- Where appropriate, options can be specified with K (kilo-) and M (mega-) suffices. So 128K instead of 131072 bytes.
- Can run for specified time, rather than a set amount of data to transfer.
- Picks the best units for the size of data being reported.
- Server handles multiple connections, rather than quitting after a single test.
- Print periodic, intermediate bandwidth, jitter, and loss reports at specified intervals.
- Run the server as a daemon.
- Run the server as a Windows NT Service
- Use representative streams to test out how link layer compression affects your achievable bandwidth.
There are pre-compiled binaries for a lot of platforms.
Perhaps you want to leave a daemon running in your server. Great!.
RHEL6 Installation:
- EPEL repository installed.
- yum install iperf
- Open a port in your firewall.
- Save this init script in /etc/init.d:
- chmod 755 /etc/init.d/iperfd
- chkconfig add iperfd
- chkconfig --on iperfd
- And you don't forget to change the port variable in the script ;)
Great writeup! A quick update given the changing times:
ReplyDelete* "chkconfig add iperfd" should be "--add"
* "chkconfig --on iperfd" is now obsolete. Using --add is enough.
Replacing "iperf" with "$prog" so one can use iperf3 instead of the older iperf more easily. As-is, the -D flag for daemon mode doesn't seem to log to $logfile. Upgrading to iperf 3.1 will allow starting with "-D --logfile=$logfile" to start in daemon mode and log to the specified logfile without using a ">".

Hey Jason, thanks for writing... I am sure it will be useful to someone in advance. I have added a Update tag in the beginning pointing to your comments. Thx!
