to find the problem i then ran the command : bin/linear.dmlc learn/linear/guide/demo.conf and got the messages below:

Every example get the same error, local environment is centos 7.

i find the problem is that ip address is not correct. I assign the host ip directly by adding hostIP = "127.0.0.1" in tracker.py, submit, 374. and it gets work!
