SSHException: not a valid EC private key file

Hi,
I've got an error when trying to attack my target. The error below is showing, but can't find any workaround. Seems that Python SSH module (paramiko) you use don't like my key type. It is an Amazon keypair that I placed in my ~/.ssh directory. I tried to reate a new one but it doesn't change a thing.

bees attack -n 2000 -c 500 --url=<URL> --headers="Accept:*/*;Accept-Encoding:gzip,deflate;Connection:keep-alive;Content-Length:25;Content-Type:application/x-www-form-urlencoded;Host:<host>;Origin:<originurl>;Referer:<Referer>" --post-file=data.json

Each of 4 bees will fire 500 rounds, 125 at a time.
Stinging URL sequentially so it will be cached for the attack.
Organizing the swarm.
Bee 0 is joining the swarm.
Bee 1 is joining the swarm.
Bee 2 is joining the swarm.
Bee 3 is joining the swarm.

SSHException: not a valid EC private key file

Kind of annoying since I can do most of my loadcharge tests with AB Testing, but not all of them.
Free to give more infos about my issue.

Same problem. Any solution so far, @RiceBowlJr ?

Adding -l ubuntu worked for me.

Although it has been three years, paramiko is still strict about the user who is supposed to "own" the private key.

Hi @mkarski
Since my load tests were pretty basic, I switched to an home made solution based on multiple instances and Ansible ad-hoc cURL commands.

Although I will try to reproduce it and find a workaround, but since I changed my comuter I may not be abel to reproduce it.
