ubuntu - Selenium Node Not Connecting to Hub, Not Opening Port -


i'm trying set demo selenium grid. have digital ocean ubuntu 14.02 droplet. (i have 2 , tried set using 2 different machines got nowhere.) i'm trying run hub , node both locally.

here input both hub, node, , nmap results.

https://gist.github.com/mekhami/d5bbecca5ff0de9d2dc9

so, node starting tcp connection reset , port it's supposed operate on closed.

i have had no luck in number of different options , configurations work.

but... of course, worked randomly once. don't know why, don't know did, know 1 brief moment, node connected , saw on grid console. tried run test , went down again , i've never seen come up.

please let me know more information can provide.

update: randomly came online again. don't know happened, might related timeout or time_wait or going on.

this because vm/server not have enough entropy available.

to resolve problem, install haveged (or other similar things).

the instructions of how install haveged on ubuntu , other linux distributions: https://www.digitalocean.com/community/tutorials/how-to-setup-additional-entropy-for-cloud-servers-using-haveged
