This is a handy tool I wrote back in 2006 as part of my diploma thesis at the University of Potsdam for measuring bandwidths and latencies on various types of networks. It’s intended to be easily extendable with new types.

Currently, following types are supported:

• BMI (network abstraction layer of PVFS)
• NEON (internal project at UP)
• SCTP
• TCP
• TCP, just connecting
• UDP
• malloc() + memcpy() + free()

The name is a backronym for “eins is not sockping” which was the predecessor by Lars Schneidenbach that it is based on.

As of writing this, it has been six years since I did anything with it thus I have no idea if it still works at all. As a true programmer prima donna I don’t dare to look inside since it might hurt my vain feelings. Therefore use it on your own discretion. I’m just putting it on GitHub so it doesn’t get lost, pull requests are welcome though.

For CLI arguments, just run eins without any of them or refer to the man page.
